1412    Content of Claims [R-08.2012]

The content of claims in a reissue application is somewhat limited, as is indicated in MPEP § 1412.01 through MPEP § 1412.03.

1412.01   Reissue Claims Must Be for Same General Invention [R-08.2012]

The reissue claims must be for the same invention as that disclosed as being the invention in the original patent, as required by 35 U.S.C. 251. The entire disclosure, not just the claim(s), is considered in determining what the patentee objectively intended as his or her invention. The proper test as to whether reissue claims are for the same invention as that disclosed as being the invention in the original patent is “an essentially factual inquiry confined to the objective intent manifested by the original patent.” In re Amos, 953 F.2d 613, 618, 21 USPQ2d 1271, 1274 (Fed. Cir. 1991) (quoting In re Rowand, 526 F.2d 558, 560, 187 USPQ 487, 489 (CCPA 1975)) (emphasis added); See also In re Mead, 581 F.2d 257, 198 USPQ 412 (CCPA 1978). The “original patent” requirement of 35 U.S.C. 251 must be understood in light of In re Amos, supra, where the Court of Appeals for the Federal Circuit stated:

We conclude that, under both Mead and Rowand, a claim submitted in reissue may be rejected under the “original patent” clause if the original specification demonstrates, to one skilled in the art, an absence of disclosure sufficient to indicate that a patentee could have claimed the subject matter. Merely finding that the subject matter was “not originally claimed, not an object of the original patent, and not depicted in the drawing,” does not answer the essential inquiry under the “original patent” clause of § 251, which is whether one skilled in the art, reading the specification, would identify the subject matter of the new claims as invented and disclosed by the patentees. In short, the absence of an “intent,” even if objectively evident from the earlier claims, the drawings, or the original objects of the invention is simply not enough to establish that the new claims are not drawn to the invention disclosed in the original patent.

953 F.2d at 618-19, 21 USPQ2d at 1275. Claims presented in a reissue application are considered to satisfy the requirement of 35 U.S.C. 251 that the claims be “for the invention disclosed in the original patent” where:

  • (A) the claims presented in the reissue application are described in the original patent specification and enabled by the original patent specification such that 35 U.S.C. 112, first paragraph is satisfied; and
  • (B) nothing in the original patent specification indicates an intent not to claim the subject matter of the claims presented in the reissue application.

The presence of some disclosure (description and enablement) in the original patent should evidence that applicant intended to claim or that applicant considered the material now claimed to be his or her invention.

The original patent specification would indicate an intent not to claim the subject matter of the claims presented in the reissue application in a situation analogous to the following:

The original patent specification discloses that composition X is not suitable (or not satisfactory) for molding an item because composition X fails to provide quick drying. The patent issues with claims directed only to composition Y. After the patent issues, it is found that composition X would be desirable for the molding in spite of the failure to provide quick drying, because of some other newly recognized benefit from composition X. The addition of a claim to composition X or a method of use thereof would not be permitted in a reissue application, because the original patent specification contained an explicit statement of intent not to claim composition X or a method of use thereof. One should understand, however, that the mere failure to claim a disclosed embodiment in the original patent (absent an explicit statement in the original patent specification of unsuitability of the embodiment) would not be grounds for prohibiting a claim to that embodiment in the reissue.

I.   FAILURE TO TIMELY FILE A DIVISIONAL APPLICATION PRIOR TO ISSUANCE OF ORIGINAL PATENT

Where a restriction (or an election of species) requirement was made in an application and applicant permitted the elected invention to issue as a patent without filing a divisional application on the non-elected invention(s), the non-elected invention(s) cannot be recovered by filing a reissue application. A reissue applicant’s failure to timely file a divisional application covering the non-elected invention(s) in response to a restriction (or an election of species) requirement is not considered to be error causing a patent granted on the elected claims to be partially inoperative by reason of claiming less than the applicant had a right to claim. Accordingly, this is not correctable by reissue of the original patent under 35 U.S.C. 251. In re Watkinson, 900 F.2d 230, 14 USPQ2d 1407 (Fed. Cir. 1990); In re Orita, 550 F.2d 1277, 1280, 193 USPQ 145, 148 (CCPA 1977); See also In re Mead, 581 F.2d 251, 198 USPQ 412 (CCPA 1978). In this situation, the reissue claims should be rejected under 35 U.S.C. 251 for lack of defect in the original patent and lack of error in obtaining the original patent. Compare with In re Doyle, 293 F.3d 1355, 63 USPQ2d 1161 (Fed. Cir. 2002) where the court permitted the patentee to file a reissue application to present a so-called linking claim, a claim broad enough to read on or link the invention elected (and patented) together with the invention not elected. The non-elected invention(s) were inadvertently not filed as a divisional application.

1412.02   Recapture of Canceled Subject Matter [R-11.2013]

A reissue will not be granted to "recapture" claimed subject matter which was surrendered in an application to obtain the original patent. Greenliant Systems, Inc. v. Xicor LLC, 692 F.3d 1261, 103 USPQ2d 1951 (Fed. Cir. 2012); In re Mostafazadeh, 643 F.3d 1353, 98 USPQ2d 1639 (Fed. Cir. 2011); North American Container, Inc. v. Plastipak Packaging, Inc., 415 F.3d 1335, 75 USPQ2d 1545 (Fed. Cir. 2005); Pannu v. Storz Instruments Inc., 258 F.3d 1366, 59 USPQ2d 1597 (Fed. Cir. 2001); Hester Industries, Inc. v. Stein, Inc., 142 F.3d 1472, 46 USPQ2d 1641 (Fed. Cir. 1998); In re Clement, 131 F.3d 1464, 45 USPQ2d 1161 (Fed. Cir. 1997); Ball Corp. v. United States, 729 F.2d 1429, 1436, 221 USPQ 289, 295 (Fed. Cir. 1984); In re Wadlinger, 496 F.2d 1200, 181 USPQ 826 (CCPA 1974); In re Richman, 409 F.2d 269, 276, 161 USPQ 359, 363-364 (CCPA 1969); In re Willingham, 282 F.2d 353, 127 USPQ 211 (CCPA 1960). The question as to whether a reissue patent violates the rule against recapture of subject matter surrendered during original prosecution is a question of law. Mostafazadeh, 643 F.3d at 1358, 98 USPQ2d at 1642.

I.   THREE STEP TEST FOR RECAPTURE:

In Clement, 131 F.3d at 1468-70, 45 USPQ2d at 1164-65, the Court of Appeals for the Federal Circuit set forth a three step test for recapture analysis. In North American Container, 415 F.3d at 1349, 75 USPQ2d at 1556, the court restated this test as follows:

We apply the recapture rule as a three-step process:

  • (1) first, we determine whether, and in what respect, the reissue claims are broader in scope than the original patent claims;
  • (2) next, we determine whether the broader aspects of the reissue claims relate to subject matter surrendered in the original prosecution; and
  • (3) finally, we determine whether the reissue claims were materially narrowed in other respects, so that the claims may not have been enlarged, and hence avoid the recapture rule.

In North American Container, the court cited Pannu, 258 F.3d at 1371, 59 USPQ2d at 1600; Hester, 142 F.3d at 1482-83, 46 USPQ2d at 1649-50; and Clement, 131 F.3d at 1468, 45 USPQ2d at 1164-65 as cases that lead to, and explain the language in, the North American Container recapture test.

A.   The First Step - Was There Broadening?

In every reissue application, the examiner must first review each claim for the presence of broadening, as compared with the scope of the claims of the patent to be reissued. A reissue claim is broadened where some limitation of the patent claims is no longer required in the reissue claim; see MPEP § 1412.03 for guidance as to the nature of a "broadening claim." If the reissue claim is not broadened in any respect as compared to the patent claims, the analysis ends; there is no recapture.

B.   The Second Step - Does Any Broadening Aspect of the Reissued Claim Relate to Surrendered Subject Matter?

Where a claim in a reissue application is broadened in some respect as compared to the patent claims, the examiner must next determine whether the broadening aspect(s) of that reissue claim relate(s) to subject matter that applicant previously surrendered during the prosecution of the original application (which became the patent to be reissued). The "original application" includes the patent family’s entire prosecution history. MBO Laboratories, Inc. v. Becton, Dickinson & Co., 602 F.3d 1306, 94 USPQ2d 1598 (Fed. Cir. 2010). Each limitation of the patent claims, which is omitted or broadened in the reissue claim, must be reviewed for this determination. This involves two sub-steps:

1.   The Two Sub-Steps:

  • (A) One must first determine whether applicant surrendered any subject matter in the prosecution of the original application that became the patent to be reissued.

    If an original patent claim limitation now being omitted or broadened in the present reissue application was originally relied upon by applicant in the original application to make the claims allowable over the art, the omitted limitation relates to subject matter previously surrendered by applicant. The reliance by applicant to define the original patent claims over the art can be by presentation of new/amended claims to define over the art, or an argument/statement by applicant that a limitation of the claim(s) defines over the art. To determine whether such reliance occurred, the examiner must review the prosecution history of the original application file (of the patent to be reissued) for surrender of claimed subject matter which may result in recapture. The prosecution history includes the rejections and applicant’s arguments made therein.

    With respect to whether applicant surrendered any subject matter, it is to be noted that a patent owner (reissue applicant) is bound by the argument that applicant relied upon to overcome an art rejection in the original application for the patent to be reissued, regardless of whether the Office adopted the argument in allowing the claims. Greenliant Systems, Inc. v. Xicor LLC, 692 F.3d 1261, 1271, 103 USPQ2d 1951, 1958 (Fed. Cir. 2012). As pointed out by the court, “[i]t does not matter whether the examiner or the Board adopted a certain argument for allowance; the sole question is whether the argument was made.” Id.

    If applicant did not surrender any subject matter in the prosecution of the original application, the analysis ends and there is no recapture.

  • (B) If applicant did surrender subject matter in the original application prosecution, the examiner must then determine whether any of the broadening of the reissue claims is in the area of the surrendered subject matter. The examiner must analyze all of the broadening aspects of the reissue claims to determine if any of the omitted/broadened limitation(s) are directed to limitations relied upon by applicant in the original application to make the claims allowable over the art.

With respect to the “second step” in the recapture analysis, it is to be noted that if the reissue claim(s), are broadened with respect to thepreviously surrendered subject matter, then recapture will be present regardless of other unrelated narrowing limitations. In the decision of In re Mostafazadeh, 643 F.3d 1353, 98 USPQ2d 1639 (Fed. Cir. 2011), the Federal Circuit stated:

[T]he recapture rule is violated when a limitation added during prosecution is eliminated entirely, even if other narrowing limitations are added to the claim. If the added limitation is modified but not eliminated, the claims must be materially narrowed relative to the surrendered subject matter such that the surrendered subject matter is not entirely or substantially recaptured. Id. at 1361.

But the focus in the analysis of the second step must be on the subject matter that was surrendered during the original application prosecution in the context of the then-existing claims, not separate inventions/embodiments/species, which do not even trigger a recapture analysis.

In the decision of In re Youman, 679 F.3d 1335, 102 USPQ2d 1862 (Fed. Cir. 2012), the Federal Circuit explained:

Whereas the recapture rule applies when surrendered subject matter is being reclaimed, overlooked aspects by definition were never claimed and thus never surrendered. See Mostafazadeh, 643 F.3d at 1360 [98 USPQ2d at 1644]. Rather, as we explained in Mostafazadeh, "overlooked aspects" is a separate inquiry under reissue that is independent of whether or not the recapture rule applies.

679 F.3d at 1347, 102 USPQ2d at 1870.

Note the following examples illustrating the above:

Assume that, in the original prosecution of the patent, applicant claimed a method of making a glass lens, where the ion implantation step used a molten bath to diffuse ions into the lens, and that step was amended to recite a pressure of 50-60 PSI and temperature between 150-200 degrees C - to define over the art. That pressure and temperature range-set is “frozen” in place for any molten bath ion implantation claim, and it cannot be deleted or broadened by reissue. However, if in the original application, applicant had failed to claim a disclosed embodiment to plasma ion implantation (i.e., using a plasma stream rather than a molten bath to provide the ions), that is a proper 35 U.S.C. 251 error, which can be corrected by reissue. Applicant can, in a reissue application, add a set of claims to plasma ion implantation, without including the “50-60 PSI and temperature between 150-200 degrees C” limitation. The “50-60 PSI - 150-200 degrees C limitation” is totally irrelevant to plasma implantation. Also, if in the original application, applicant failed to claim the method of placing two lenses made by the invention in a specified series to modulate a laser for cutting chocolate, that too is a proper 35 U.S.C. 251 error, which can be corrected by reissue. In this lens placement method, it does not matter how the specific lens having the implanted ion gradient was made, and the “50-60 PSI and temperature between 150-200 degrees C” limitation is again not relevant. Hester Industries, Inc. v. Stein, Inc., supra, addressed this concept of overlooked aspects, stating:

[T]his principle [i.e., avoidance of the recapture rule], in appropriate cases, may operate to overcome the recapture rule when the reissue claims are materially narrower in other overlooked aspects of the invention. The purpose of this exception to the recapture rule is to allow the patentee to obtain through reissue a scope of protection to which he is rightfully entitled for such overlooked aspects.

142 F.3d at 1482-83, 46 USPQ2d at 1649-50. (Emphasis added)

See also B.E. Meyers & Co. v. United States, 47 Fed.Cl. 200, 56 USPQ2d 1110 (Fed. Cl. 2000), where the Court of Federal Claims permitted the complete removal of a limitation that was added to obtain the patent, where the replacement limitation provided a separate invention.

2.   Examples of the Second Step Analysis:

  • (A) Example (1) - Argument without amendment:

In Hester, supra, the Federal Circuit held that the surrender that forms the basis for impermissible recapture "can occur through arguments alone" . 142 F.3d at 1482, 46 USPQ2d at 1649. For example, assume that limitation A of the patent claims is omitted in the reissue claims. This omission provides a broadening aspect in the reissue claims, as compared to the claims of the patent. If the omitted limitation A was argued in the original application to make the application claims allowable over the art in the application, then the omitted limitation relates to subject matter previously surrendered in the original application, and recapture will exist. Accordingly, where claims are broadened in a reissue application, the examiner should review the prosecution history of the original patent file for recapture, even where the claims were never amended during the prosecution of the application which resulted in the patent. Note: The argument that the claim limitation defined over the rejection must have been specific as to the limitation relied upon, rather than a general statement regarding the claims as a whole. A general "boiler plate" sentence in the original application will not, by itself, be sufficient to establish surrender and recapture.

An example of a general "boiler plate" sentence of argument is:

In closing, it is argued that the limitations of claims 1-7 distinguish the claims from the teachings of the prior art, and claims 1-7 are thus patentable.

An argument that merely states that all the limitations of the claims define over the prior art will also not, by itself, be sufficient to establish surrender and recapture. An example is:

Claims 1-5 set forth a power-train apparatus which comprises the combination of A+B+C+D+E. The prior art of record does not disclose or otherwise teach, providing a material-transfer apparatus as defined by the limitations of claim 1, including an A member and a B member, both connected to a C member, with all three being aligned with the D and E members.

This statement is simply a restatement of the entirety of claim 1 as allowed. No measure of surrender could be gleaned from such a statement of reasons for allowance. See Ex parte Yamaguchi, 61 USPQ2d 1043 (Bd. Pat. App. & Inter. 2001)(reported but unpublished, precedential).

In both of the above examples, the argument does not provide an indication of what specific limitations, e.g., specific element or step of the claims, cooperative effect, or other aspect of the claims, are being relied upon for patentability. Thus, applicant has not surrendered anything.

  • (B) Example (2) - Amendment of the claims without argument:

The limitation omitted in the reissue claim(s) was added in the original application claims for the purpose of making the application claims allowable over a rejection or objection made in the application. Even though applicant made no argument on the record that the limitation was added to obviate the rejection, the nature of the addition to the claim can show that the limitation was added in direct reply to the rejection. This too will establish the omitted limitation as relating to subject matter previously surrendered. To illustrate this, note the following example:

The original application claims recite limitations A+B+C, and the Office action rejection combines two references to show A+B+C. In the amendment replying to the Office action, applicant adds limitation D to A+B+C in the claims, but makes no argument as to that addition. The examiner then allows the claims. Even though there is no argument as to the addition of limitation D, it must be presumed that the D limitation was added to obviate the rejection. The subsequent deletion of (omission of) limitation D in the reissue claims would be presumed to be a broadening in an aspect of the reissue claims related to surrendered subject matter. Accordingly, the reissued claims would be barred by the recapture doctrine. The above result would be the same whether the addition of limitation D in the original application was by way of applicant’s amendment or by way of an examiner’s amendment with authorization by applicant.

  • (C) Example (3) - Who can make the surrendering argument?

Assume that the limitation A omitted in the reissue claims was present in the claims of the original application. The examiner’s reasons for allowance in the original application stated that it was that limitation A which distinguished over a potential combination of references X and Y. Applicant did not present on the record a counter statement or comment as to the examiner’s reasons for allowance, and permitted the claims to issue.

Ex parte Yamaguchi, supra, held that a surrender of claimed subject matter cannot be based solely upon an applicant’s failure to respond to, or failure to challenge, an examiner’s statement made during the prosecution of an application. Applicant is bound only by applicant’s revision of the application claims or a positive argument/statement by applicant. An applicant’s failure to present on the record a counter statement or comment as to an examiner’s reasons for allowance does not give rise to any implication that applicant agreed with or acquiesced in the examiner’s reasoning for allowance. Thus, the failure to present a counter statement or comment as to the examiner’s statement of reasons for allowance does not give rise to any finding of surrender. The examiner’s statement of reasons for allowance in the original application cannot, by itself, provide the basis for establishing surrender and recapture.

It is only in the situation where applicant does file comments on the statement of reasons for allowance, that surrender may have occurred. Note the following two scenarios in which an applicant files comments:

Scenario 1- There is Surrender: The examiner’s statement of reasons for allowance in the original application stated that it was limitation C (of the combination of ABC) which distinguished over a potential combining of references X and Y, in that limitation C provided increased speed to the process. Applicant filed comments on the examiner’s statement of reasons for allowance essentially supporting the examiner’ s reasons. The limitation C is thus established as relating to subject matter previously surrendered.

Scenario 2- There is No Surrender: On the other hand, if applicant’s comments on the examiner’s statement of reasons for allowance contain a counter statement that it is limitation B (of the combination of ABC), rather than C, which distinguishes the claims over the art, then limitation B would constitute surrendered subject matter, and limitation C has not been surrendered.

C.   The Third Step - Were the reissued claims materially narrowed in other respects, and hence avoid the recapture rule?

As pointed out above, the third prong of the recapture determination set forth in North American Container considers the significance of the claim limitations that were added and deleted, during prosecution of the patent (to be reissued) to determine whether the reissue claims should be barred as recapture.

The following discussion addresses analyzing the reissue claims, and which claims are to be compared to the reissue claims in determining the issue of surrender (for reissue recapture).

When analyzing a reissue claim for the possibility of impermissible recapture, there are two different types of analysis that must be performed. If the reissue claim "fails" either analysis, recapture exists.

First, the reissue claim must be compared to any claims canceled or amended during prosecution of the original application. It is impermissible recapture for a reissue claim to be as broad as, or broader in scope than any claim that was canceled or amended in the original prosecution to define over the art. Claim scope that was canceled or amended is deemed surrendered and therefore barred from reissue. Clement, 131 F.3d at 1470, 45 USPQ2d at 1165.

Second, it must be determined whether the reissue claim omits or broadens any limitation that was added or argued during the original prosecution to overcome an art rejection. Such an omission in a reissue claim, even if it is accompanied by other limitations making the reissue claim narrower than the patent claim in other aspects, is impermissible recapture. Pannu, 258 F.3d at 1371-72, 59 USPQ2d at 1600. In any broadening reissue application, the examiner will determine, on a claim-by-claim basis, whether the broadening in the reissue application claim(s) relates to subject matter that was surrendered during the examination of the patent for which reissue is requested) by an amendment narrowing claim scope in order to overcome a rejection and/or argument relying on a claim limitation in order to overcome a rejection.

A) If surrendered subject matter has been entirely eliminated from a claim present in the reissue application, then a recapture rejection under 35 U.S.C. 251 is proper and must be made for that claim. Stated another way, if a claim limitation present in the original patent that was added to overcome a rejection or that was argued by applicant to distinguish over the prior art is entirely eliminated from a claim in the reissue application, then a recapture rejection under 35 U.S.C. 251 is proper and must be made for that claim.

B) If the surrendered subject matter has not been entirely eliminated from a claim in the reissue application (i.e., the amendment narrowing the claim or the argued limitation has not been entirely eliminated from the claim in the reissue application), but rather it has been made less restrictive in the reissue application claim (such that the claim is broadened), the analysis (based on In re Mostafazadeh, 643 F.3d 1353, 98 USPQ2d 1639 (Fed. Cir. 2011) and In re Youman, 679 F.3d 1335, 102 USPQ2d 1862 (Fed. Cir. 2012)) is as follows:

It must be determined what portion of the amendment or argued limitation has been retained, and whether the retained portion materially narrows the original claims to avoid recapture. See Youman, 679 F.3d at 1346 n.4, 102 USPQ2d at 1870 n.4 ("’original claims’ are defined as ’the claims before surrender’"). “[I]f the patentee modifies the added [or argued] limitation such that it is broader than the patented claim yet still materially narrows relative to the original claim, the recapture rule does not bar reissue.” Id. at 1347, 102 USPQ2d at 1870. On the other hand, if the retained portion of the modified limitation is “well known in the prior art,” impermissible recapture has not been avoided. See Mostafazadeh, 643 F.3d at 1361, 98 USPQ2d at 1644. It is to be noted that if the portion of the modified limitation is well known in the prior art, then impermissible recapture exists, even in a case where a further limitation which is not related to the surrendered subject matter (i.e., a limitation that does not materially narrow the claims) has been added to define the claims over the art. Id.

Even “[i]f the modified limitation does not materially narrow (or, in other cases, the limitation is eliminated),” it may be that “the reissued claims were materially narrowed in other respects so that the claims have not been enlarged, and hence avoid the recapture rule.” Youman, 679 F.3d at 1347, 102 USPQ2d at 1870. In other words, even if the modified limitation does not materially narrow, the reissue applicant may have added a new limitation that still relates to surrendered subject matter. The material narrowing must relate to what was argued by applicant in the original application, to define the claim over the art. Greenliant Systems, Inc. et al v. Xicor LLC, 692 F.3d 1261, 1271, 103 USPQ2d 1951, 1958 (Fed. Cir. 2012). If the reissue applicant believes that “the reissued claims were materially narrowed in other respects,” the reissue applicant should point out explicitly what limitation has been added to the claims to materially narrow and how it materially narrows the claims.

The following discussion is provided for analyzing the reissue claims.

1.   Comparing Reissue Claims Narrowed/Broadened Vis-à-vis the Canceled Claims

DEFINITIONS:

"Canceled claims," in the context of recapture case law, are claims canceled from the original application to obtain the patent for which reissue is now being sought. The claims

  • (A) can simply be canceled and not replaced by others, or
  • (B) can be canceled and replaced by other claims which are more specific than the canceled claims in at least one aspect (to thereby define over the art of record). The "replacement claims" can be new claims which are narrower than the canceled claims, or can be the same claims amended to be narrower than the canceled version of the claims.

“Surrender-generating limitation” – The “limitation” presented, argued, or stated to make the claims patentable over the art (in the application) “generates” the surrender of claimed subject matter. For the sake of simplification, this limitation will be referred to throughout this section as the surrender-generating limitation.

(a)   Reissue Claims Are Same or Broader in Scope Than Canceled Claims in All Aspects:

The recapture rule bars the patentee from acquiring, through reissue, claims that are in all aspects (A) of the same scope as, or (B) broader in scope than, those claims canceled from the original application to obtain a patent. Ball Corp. v. United States, 729 F.2d at 1436, 221 USPQ at 295.

(b)   Reissue Claims are Narrower in Scope Than Canceled Claims in at Least One Aspect:

If the reissue claims are equal in scope to, or narrower than, the claims of the original patent (as opposed to the claims "canceled from the application" ) in all aspects, then there can never be recapture. The discussion that follows is not directed to that situation. It is rather directed to the situation where the reissue claims are narrower than the claims 'canceled' from the application in some aspect, but are broader than the claims of the original patent in some other aspect.

If the reissue claims are narrower in scope than the claims canceled from the original application by inclusion of the entirety of the limitation addedto define the original application claims over the art, there will be no recapture, even if the reissue claims are broader than the canceled claims in some other aspect (i.e., an aspect not related to the surrender made in the original application).

Assume combination AB was originally presented in the application, and was amended in response to an art rejection to add element C and thus provide ABC (after which the patent issued). The reissue claims are then directed to combination ABbroadenedC. The ABbroadenedC claims are narrower in scope when compared with the canceled claim subject matter AB with respect to the addition of C (which was added in the application to overcome the art), and they retain surrender-generating limitation C; thus, there is no recapture.

As another example, assume combination ABZ was originally presented in the application, and was amended in response to an art rejection to add element C and thus provide ABZC (after which the patent issued). The reissue claims are then directed to combination ABC (i.e., element Z is deleted from the canceled claims, while element C remains present). The ABC claims of the reissue are narrower in scope as compared to the canceled-from-the-original-application claim subject matter ABZ with respect to the addition of C (which was added in the application to overcome the art), and they retain surrender-generating limitation C; thus, there is no recapture.

2.   Comparing Reissue Claims Narrowed/Broadened Vis-à-vis the Patent Claims

The "patent claims," in the context of recapture case law, are claims that issued in the original patent for which reissue is now being sought. As pointed out above, where the reissue claims are narrower than the claims of the original patent in all aspects, then there can never be recapture. If reissue claims are equal in scope to the patent claims, there is no recapture as to those reissue claims. Where, however, reissue claims are both broadened and narrowed as compared with the original patent claims, the nature of the broadening and narrowing must be examined to determine whether the reissue claims are barred as being recapture of surrendered subject matter. If the claims are "broader than they are narrower in a manner directly pertinent to the subject matter... surrendered during prosecution" (Clement, 131 F.3d at 1471, 45 USPQ2d at 1166), then recapture will bar the claims. This narrowing/broadening vis-à-vis the patent is broken down into four possibilities that will now be addressed.

If a claim is presented in a reissue application that omits, in its entirety, the surrender-generating limitation, that claim impermissibly recaptures what was previously surrendered, and that claim is barred under 35 U.S.C. 251. Note, however, subsection V., below, “REBUTTAL BY THE REISSUE APPLICANT,” which points out how the recapture finding of the Office can be rebutted by applicant, in some limited instances, by showing that material narrowing is present in the claims.

(a)   Reissue Claims are Narrower in Scope Than Patent Claims, in Area Not Directed to Amendment/Argument Made to Overcome Art Rejection in Original Prosecution; are Broader in Scope by Omitting Limitation(s) Added/Argued To Overcome Art Rejection in Original Prosecution:

In this case, there is recapture.

This situation is where the patent claims are directed to combination ABC and the reissue claims are directed to ABD. Element C was either a limitation added to AB to obtain allowance of the original patent, or was argued by applicant to define over the art (or both). Thus, addition of C (and/or argument as to C) has resulted in the surrender of any combination of A & B that does not include C; this is the surrendered subject matter. Element D, on the other hand, is not related to the surrendered subject matter. Thus, the reissue claim, which no longer contains C, is broadened in an area related to the surrender, and the narrowing by the addition of D does not save the claim from recapture because D is not related to the surrendered subject matter.

Reissue claims that are broader than the original patent claims by not including the surrender-generating limitation (element C, in the example given) will be barred by the recapture rule even though there is narrowing of the claims not related to the surrender-generating limitation. As stated in the decision of In re Clement, 131 F.3d at 1470, 45 USPQ2d at 1165, if the reissue claim is broader in an aspect germane to a prior art rejection, but narrower in another aspect completely unrelated to the rejection, the recapture rule bars the claim. Pannu, 258 F.3d 1366, 59 USPQ2d 1597, provides a fact situation in which this scenario was held to be recapture.

(b)   Reissue Claims are Narrower or Equal in Scope, in Area Directed to Amendment/Argument Made to Overcome Art Rejection in Original Prosecution; are Broader in Scope in Area Not Directed to Amendment/Argument:

In this case, there is no recapture.

This situation is where the patent claims are directed to combination ABCDE and the reissue claims are directed to ABDE (element C is omitted). Assume that the combination of ABCD was present in the original application as it was filed, and element E was later added to define over that art. No argument was ever presented as to elements A-C defining over the art.

In this situation, the ABCDE combination of the patent can be broadened (in the reissue application) to omit element C, and thereby claim the combination of ABDE, where element E (the surrender generating limitation) is not omitted. There would be no recapture in this instance. (If an argument had been presented as to element C defining over the art, in addition to the addition of element E, then the ABCDE combination could not be broadened to omit element C and thereby claim combination of ABDE. This would be recapture; see the above discussion as to surrender and recapture based upon argument.)

Additionally, the reissue claims are certainly permitted to recite combination ABDEspecific (where surrender-generating element E is narrowed). The patent claims have been broadened in an area not directed to the surrender (by omitting element C) and narrowed in the area of surrender (by narrowing element E to Especific). This is clearly permitted.

As another example, assume limitation C was added to application claims AB to obtain the patent to ABC, and now the reissue application presents claims to AC or ABbroadC. Such reissue claims avoid the effect of the recapture rule because they are broader in a way that does not attempt to reclaim what was surrendered earlier. Mentor Corp. v. Coloplast, Inc., 998 F.2d 992, 994, 27 USPQ2d 1521, 1525 (Fed. Cir. 1993). Such claims are considered to be broader in an aspect not "germane to a prior art rejection," and thus are not barred by recapture. Note In re Clement, 131 F.3d at 1470, 45 USPQ2d at 1165.

Reissue claims that are broader than the original patent claims by deletion of a limitation or claim requirement other than the "surrender-generating limitation" will avoid the effect of the recapture rule, regardless of the nature of the narrowing in the claims, and even if the claims are not narrowed at all from the scope of the patent claims.

(c)   Reissue Claims are Narrower in Scope in Area Not Directed to Amendment/Argument Made to Overcome Art Rejection in Original Prosecution; are Broader in Scope in Area Not Directed to the Amendment/Argument:

In this instance, there is clearly no recapture. In the reissue application, there has been no change in the claims related to the matter surrendered in the original application for the patent.

In this instance, element C was added to the AB combination to provide ABC and define over the art, and the patent was issued. The reissue omits element B and adds element Z, to thus claim ACZ. There is no recapture because the surrender generating element C has not been modified in any way. (Note, however, that if, when element C was added to AB, applicant argued that the association of newly added C with B provides a synergistic (unexpected) result to thus define over the art, then neither element B nor element C could be omitted in the reissue application.)

(d)   Reissue Claims Broader in Scope in Area Directed to Amendment/Argument Made to Overcome Art Rejection in Original Prosecution; but Reissue Claims Retain, in Broadened Form, the Limitation(s) Argued/Added to Overcome Art Rejection in Original Prosecution:

In this case, there may be recapture.

Assume the combination AB was originally claimed in the application, and was amended in reply to an art rejection to add element C and thus provide the combination ABC (after which the patent issued). A reissue application is then filed, and the reissue application claims are directed to the combination ABCbroadened. The ABCbroadened claims are narrowed in scope when compared with the canceled claim subject matter AB, because of the addition of Cbroadened. Thus, the claims retain, in broadened form, the limitation argued/added to overcome art rejection in original prosecution. In this instance, a recapture rejection can be made even though ABCbroadened is narrower than canceled claim subject matter AB , but only if Cbroadened was “well known in the prior art”. See In re Mostafazadeh, 643 F.3d 1353, 1361, 98 USPQ2d 1639, 1644 (Fed. Cir. 2011). On the other hand, “if the patentee modifies the added limitation such that it is broader than the patented claim yet still materially narrows relative to the original claim, the recapture rule does not bar reissue.” In re Youman et al, 679 F.3d 1335, 1347, 102 USPQ2d 1862, 1870 (Fed. Cir. 2012). Any recapture of surrendered subject matter that was in prior art of the original prosecution forms the ceiling for determining whether the modified limitation is materially narrowing. Id.

II.   REISSUE TO TAKE ADVANTAGE OF pre-AIA 35 U.S.C. 103(b):

For patents issued on an application subject to the pre-AIA prior art regime (pre-AIA patents), a patentee may file a reissue application to permit consideration of process claims which qualify for pre-AIA 35 U.S.C. 103(b) treatment if a patent is granted on an application entitled to the benefit of pre-AIA 35 U.S.C. 103(b), without an election having been made as a result of  error without deceptive intent. See MPEP § 706.02(n). This is not to be considered a recapture. The addition of process claims, however, will generally be considered to be a broadening of the invention (Ex parte Wikdahl, 10 USPQ2d 1546 (Bd. Pat. App. & Inter. 1989)), and such addition must be applied for within two years of the grant of the original patent, or in an appropriate continuing broadening reissue application claiming the benefit of a prior filed broadening reissue application filed within two years of the grant of the original patent. See also MPEP § 1412.03 as to broadened claims.

III.   REISSUE FOR ARTICLE CLAIMS WHICH ARE FUNCTIONAL DESCRIPTIVE MATERIAL STORED ON A COMPUTER-READABLE MEDIUM:

A patentee may file a reissue application to permit consideration of article of manufacture claims (not presented in the patent to be reissued) which are functional descriptive material stored on a computer-readable medium, where these article claims correspond to the process or machine claims which have been patented. The addition of these “article” claims will generally be considered to be a broadening of the invention (Ex parte Wikdahl, 10 USPQ2d 1546 (Bd. Pat. App. & Inter. 1989)), and such addition must be applied for within two years of the grant of the original patent. See also MPEP § 1412.03 as to broadened claims.

IV.   REJECTION BASED UPON RECAPTURE:

Reissue claims which recapture surrendered subject matter should be rejected using form paragraph 14.17.

¶ 14.17    Rejection, 35 U.S.C. 251, Recapture

Claim[1] rejected under 35 U.S.C. 251 as being an impermissible recapture of broadened claimed subject matter surrendered in the application for the patent upon which the present reissue is based. See Greenliant Systems, Inc. et al v. Xicor LLC, 692 F.3d 1261, 103 USPQ2d 1951 (Fed. Cir. 2012); In re Shahram Mostafazadeh and Joseph O. Smith, 643 F.3d 1353, 98 USPQ2d 1639 (Fed. Cir. 2011); North American Container, Inc. v. Plastipak Packaging, Inc., 415 F.3d 1335, 75 USPQ2d 1545 (Fed. Cir. 2005); Pannu v. Storz Instruments Inc., 258 F.3d 1366, 59 USPQ2d 1597 (Fed. Cir. 2001); Hester Industries, Inc. v. Stein, Inc., 142 F.3d 1472, 46 USPQ2d 1641 (Fed. Cir. 1998); In re Clement, 131 F.3d 1464, 45 USPQ2d 1161 (Fed. Cir. 1997); Ball Corp. v. United States, 729 F.2d 1429, 1436, 221 USPQ 289, 295 (Fed. Cir. 1984). A broadening aspect is present in the reissue which was not present in the application for patent. The record of the application for the patent shows that the broadening aspect (in the reissue) relates to claimed subject matter that applicant previously surrendered during the prosecution of the application. Accordingly, the narrow scope of the claims in the patent was not an error within the meaning of 35 U.S.C. 251, and the broader scope of claim subject matter surrendered in the application for the patent cannot be recaptured by the filing of the present reissue application.

[2]

Examiner Note:

In bracket 2, the examiner should explain the specifics of why recapture exists, including an identification of the omitted/broadened claim limitations in the reissue which provide the “broadening aspect” to the claim(s), and where in the original application the narrowed claim scope was presented/argued to obviate a rejection/objection. See MPEP § 1412.02.

V.   REBUTTAL BY THE REISSUE APPLICANT

The reissue applicant may rebut a recapture rejection by demonstrating that a claim rejected for recapture includes one or more claim limitations that “materially narrow” the reissue claims in a way that relates to the subject matter surrendered during original prosecution.

Examples of reissue application claims that are to be rejected for recapture under 35 U.S.C. 251 include:

Assume that the original application claim ABCD was amended during prosecution and results in a patent claim ABCDE.

1. ABCD → Eliminates E, the surrender generating limitation (SGL).

2. ABCDF → Eliminates E, the SGL; adds narrowing limitation F.

3. ABCDEBROADER → Broadens E, the SGL; EBROADER is well known in the art.

4. ABCDEBROADERF → Broadens E; EBROADER is well known in the art; adds narrowing limitation F.

In these four examples, a recapture rejection would be made. For examples 2 and 4, applicant may try to rebut the recapture rejections by showing that limitation F “materially narrows” the reissue claims in a way that relates to the subject matter surrendered during original prosecution. If such is the case, the reissue applicant should point out explicitly what limitation has been added to the claims (in this case, limitation F) and how it materially narrows the claims.

1412.03   Broadening Reissue Claims [R-11.2013]

35 U.S.C. 251  Reissue of defective patents

  • (d) REISSUE PATENT ENLARGING SCOPE OF CLAIMS.—No reissued patent shall be granted enlarging the scope of the claims of the original patent unless applied for within two years from the grant of the original patent.

*****

35 U.S.C. 251(d) and the corresponding final paragraph of pre-AIA 35 U.S.C. 251 prescribe a 2-year limit for filing applications for broadening reissues.

I.   MEANING OF “BROADENED REISSUE CLAIM”

A broadened reissue claim is a claim which enlarges the scope of the claims of the patent, i.e., a claim which is greater in scope than each and every claim of the original patent. If a disclaimer is filed in the patent prior to the filing of a reissue application, the disclaimed claims are not part of the “original patent” under 35 U.S.C. 251. The Court in Vectra Fitness Inc. v. TNWK Corp., 162 F.3d 1379, 1383, 49 USPQ2d 1144, 1147 (Fed. Cir. 1998) held that a reissue application violated the statutory prohibition under 35 U.S.C. 251 against broadening the scope of the patent more than 2 years after its grant because the reissue claims are broader than the claims that remain after the disclaimer, even though the reissue claims are narrower than the claims that were disclaimed by the patentee before reissue. The reissue application was bounded by the claims remaining in the patent after a disclaimer is filed. A claim of a reissue application enlarges the scope of the claims of the patent if it is broader in at least one respect, even though it may be narrower in other respects. See, e.g., 37 CFR 1.175(b). A claim in the reissue application which includes subject matter not covered by the patent claims enlarges the scope of the patent claims. For example, if any amended or newly added claim in the reissue contains within its scope any conceivable product or process which would not have infringed the patent, then that reissue claim would be broader than the patent claims. Tillotson, Ltd. v. Walbro Corp., 831 F.2d 1033, 1037 n.2, 4 USPQ2d 1450, 1453 n.2 (Fed. Cir. 1987); In re Ruth, 278 F.2d 729, 730, 126 USPQ 155, 156 (CCPA 1960); In re Rogoff, 261 F.2d 601, 603, 120 USPQ 185, 186 (CCPA 1958). A claim which covers something that the original claims do not is a broadened claim. A claim would be considered a broadening claim if the patent owner would be able to sue any party for infringement who previously could not have been sued for infringement. Thus, where the original patent claims only the process, and the reissue application newly adds product claims, the scope of the claims has been broadened because a party could not necessarily be sued for infringement of the product based on the claims of the original patent (if it were made by a different process).

The addition of combination claims in a reissue application where only subcombination claims were present in the original patent could be a broadening of the invention. The question which must be resolved in this case is whether the combination claims added in the reissue would be for “the invention as claimed” in the original patent. See Ex parte Wikdahl, 10 USPQ2d at 1549. The newly added combination claims should be analyzed to determine whether they contain every limitation of the subcombination of any claim of the original patent. If the combination claims (added in the reissue) contain every limitation of the subcombination (which was claimed in the original application), then infringement of the combination must also result in infringement of the subcombination. Accordingly, the patent owner could not, if a reissue patent issues with the combination claims, sue any new party for infringement who could not have been sued for infringement of the original patent. Therefore, broadening does not exist, in spite of the addition of the combination. However, filing a reissue application to merely add combination claim(s) that require all the limitations of a subcombination claim, which subcombination claim was present in the original patent, would not provide an error that is correctable by reissue as defined by 35 U.S.C. 251; see the discussion in MPEP § 1402.

II.   SCOPE OF DEPENDENT CLAIM ENLARGED - NOT BROADENING

As pointed out above, a claim will be considered a broadened reissue claim when it is greater in scope than each and every claim of the patent to be reissued. A corollary of this is that a claim which has been broadened in a reissue as compared to its scope in the patent is not a broadened reissue claim if it is narrower than, or equal in scope to, any other claim which appears in the patent. A common example of this is where dependent claim 2 is broadened via the reissue (other than the addition of a process step to convert an intermediate to a final product), but independent claim 1 on which it is based is not broadened. Because a dependent claim is construed to contain all the limitations of the claim upon which it depends, claim 2 must be at least as narrow as claim 1 and is thus not a broadened reissue claim.

III.   NEW CATEGORY OF INVENTION ADDED IN REISSUE - GENERALLY IS BROADENING

The addition of process claims as a new category of invention to be claimed in the patent (i.e., where there were no method claims present in the original patent) is generally considered as being a broadening of the invention. See Ex parte Wikdahl, 10 USPQ2d 1546 1549 (Bd. Pat. App. & Inter. 1989). A situation may arise, however, where the reissue application adds a limitation (or limitations) to process A of making the product A claimed in the original patent claims. For example:

  • (1) a process of using the product A (made by the process of the original patent) to make a product B, disclosed but not claimed in the original patent; or
  • (2) a process of using the product A to carry out a process B disclosed but not claimed in the original patent.

Although this amendment of the claims adds a method of making product B or adds a method of using product A, this is not broadening (i.e., this is not an enlargement of the scope of the original patent) because the "newly claimed invention" contains all the limitations of the original patent claim(s).

IV.   WHEN A BROADENED CLAIM CAN BE PRESENTED

A broadened claim can be presented within two years from the grant of the original patent in a reissue application. In addition, a broadened claim can be presented after two years from the grant of the original patent in a broadening reissue application which was filed within two years from the grant. Where any intent to broaden is unequivocally indicated in the reissue application within the two years from the patent grant, a broadened claim can subsequently be presented in the reissue after the two year period. (Note: A statement that “the patent is wholly or partly inoperative by reason of claiming more or less than applicant had a right to claim” is NOT an unequivocal statement of an intent to broaden.) Thus, a broadened claim may be presented in a reissue application after the two years, even though the broadened claim presented after the two years is different than the broadened claim presented within the two years. Finally, if intent to broaden is indicated in a parent reissue application within the two years, a broadened claim can be presented in a continuing (continuation or divisional) reissue application after the two year period. See In re Staats, 671 F.3d 1350, 101 USPQ2d 1930 (Fed. Cir. 2012) which dealt with a continuation of a first reissue application in which the first reissue application was filed within two years of the patent grant. The broadened claims in the continuation reissue application were to an embodiment “alternative” to, and “unrelated” to, the broadened claims of the first reissue application that were filed within the 2-year limit. Notice of broadening was found to be sufficient in this instance, with the court holding that there is no basis for requiring the later broadened claims in the continuation reissue application to be related to, or directed to the same embodiment as in the first reissue application.Id. at 1355, 101 USPQ2d at 1934. “[A]fter a broadening reissue application has been filed within the two year statutory period, an applicant is ‘not barred from making further broadening changes’ after the two year period” regardless of whether the further broadening changes are unrelated to the prior broadening reissue application. Id. A reissue application filed on the 2-year anniversary date from the patent grant is considered to be filed within 2 years of the patent grant. See Switzer v. Sockman, 333 F.2d 935, 142 USPQ 226 (CCPA 1964) for a similar rule in interferences.

See also the following cases which pertain to broadened reissues:

In re Graff, 111 F.3d 874, 877, 42 USPQ2d 1471, 1473-74 (Fed. Cir. 1997) (Broadened claims in a continuing reissue application were properly rejected under 35 U.S.C. 251 because the proposal for broadened claims was not made (in the parent reissue application) within two years from the grant of the original patent and the public was not notified that broadened claims were being sought until after the two-year period elapsed.);

In re Fotland, 779 F.2d 31, 228 USPQ 193 (Fed. Cir. 1985), cert. denied, 476 U.S. 1183 (1986) (The failure by an applicant to include an oath or declaration indicating a desire to seek broadened claims within two years of the patent grant will bar a subsequent attempt to broaden the claims after the two year limit.

In re Bennett, 766 F.2d 524, 528, 226 USPQ 413, 416 (Fed. Cir. 1985) (en banc) (A reissue application with broadened claims was filed within two years of the patent grant; however, the declaration was executed by the assignee rather than the inventor. The Federal Circuit permitted correction of the improperly executed declaration to be made more than two years after the patent grant.);

In re Doll, 419 F.2d 925, 928, 164 USPQ 218, 220 (CCPA 1970) (If the reissue application is timely filed within two years of the original patent grant and the applicant indicates in the oath or declaration that the claims will be broadened, then applicant may subsequently broaden the claims in the pending reissue prosecution even if the additional broadening occurs beyond the two year limit.).

Form paragraphs 14.12 and 14.13 may be used in rejections based on improper broadened reissue claims.

¶ 14.12    Rejection, 35 U.S.C. 251, Broadened Claims After Two Years

Claim [1] rejected under 35 U.S.C. 251 as being broadened in a reissue application filed outside the two year statutory period. [2] A claim is broader in scope than the original claims if it contains within its scope any conceivable product or process which would not have infringed the original patent. A claim is broadened if it is broader in any one respect even though it may be narrower in other respects.

Examiner Note:

The claim limitations that broaden the scope should be identified and explained in bracket 2. See MPEP §§ 706.03(x) and 1412.03.

¶ 14.13    Rejection, 35 U.S.C. 251, Broadened Claims Filed by Assignee

Claim [1] rejected under 35 U.S.C. 251 as being improperly broadened in a reissue application made and sworn to by the assignee. The application for reissue may be made and sworn to by the assignee of the entire interest only if the application does not seek to enlarge the scope of the claims of the original patent or, for reissue applications filed on or after September 16, 2012, the application for the original patent was filed by the assignee of the entire interest under 37 CFR 1.46.

[2] A claim is broader in scope than the original claims if it contains within its scope any conceivable product or process which would not have infringed the original patent. A claim is broadened if it is broader in any one respect even though it may be narrower in other respects.

Examiner Note:

The claim limitations that broaden the scope should be identified and explained in bracket 2. See MPEP §§ 706.03(x) and 1412.03.

V.   BROADENING REISSUE - OATH/DECLARATION REQUIREMENTS

A.   Reissue Application Filed On or After September 16, 2012

A broadening reissue application filed on or after September 16, 2012 must be applied for by all of the inventors (patentees), that is, the original reissue oath or declaration must be signed by all of the inventors, unless the application for the patent (for which reissue is requested) was filed under 37 CFR 1.46 by the assignee of the entire interest (see 37 CFR 1.175(c)(2)). See also MPEP § 1414. A supplemental oath or declaration to account for errors corrected subsequent to the original oath or declaration is not needed for the application; however, a replacement oath or declaration would still be required where there is a failure to identify any error, or a failure to identify at least one error of the type that would support a reissue. Such a replacement oath or declaration must be signed by all of the inventors, unless the application for the patent (for which reissue is requested) was filed under 37 CFR 1.46 by the assignee of the entire interest.

For any reissue application filed on or after September 16, 2012, the inventor’s oath or declaration must identify a specific claim that the application seeks to broaden. See 37 CFR 1.175(b). A general statement, e.g., that all claims are broadened, is not sufficient to satisfy this requirement.

B.   Reissue Application Filed Before September 16, 2012

A broadening reissue application filed before September 16, 2012 must be applied for by all of the inventors (patentees), that is, the original reissue oath or declaration must be signed by all of the inventors. See also MPEP § 1414. The error in not presenting broader claims must have been made without deceptive intent. If a supplemental oath or declaration in a broadening reissue application is needed in the application in order to fulfill the requirements of 37 CFR 1.175, the supplemental reissue oath or declaration must be signed by all of the inventors. See In re Hayes, 53 USPQ2d 1222 (Comm’r Pat. 1999) and MPEP § 1414.03.

1412.04   Correction of Inventorship By Reissue [R-11.2013]

The correction of misjoinder of inventors has been held to be a ground for reissue. See Ex parte Scudder, 169 USPQ 814, 815 (Bd. App. 1971) wherein the Board held that 35 U.S.C. 251 authorizes reissue applications to correct misjoinder of inventors where 35 U.S.C. 256 is inadequate. See also A.F. Stoddard & Co. v. Dann, 564 F.2d 556, 567 n.16, 195 USPQ 97, 106 n.16 (D.C. Cir. 1977) wherein correction of inventorship from sole inventor A to sole inventor B was permitted in a reissue application. The court noted that reissue by itself is a vehicle for correcting inventorship in a patent.

See MPEP §§ 602.01(c) et seq. for correction of inventorship in an application other than a reissue application.

I.   CERTIFICATE OF CORRECTION AS A VEHICLE FOR CORRECTING INVENTORSHIP

While reissue is a vehicle for correcting inventorship in a patent, correction of inventorship should be effected under the provisions of 35 U.S.C. 256 and 37 CFR 1.324 by filing a request for a Certificate of Correction if:

  • (A) the only change being made in the patent is to correct the inventorship; and
  • (B) all parties are in agreement and the inventorship issue is not contested.

See MPEP § 1481.02 for the procedure to be followed to obtain a Certificate of Correction for correction of inventorship.

II.   REISSUE AS A VEHICLE FOR CORRECTING INVENTORSHIP

Where the provisions of 35 U.S.C. 256 and 37 CFR 1.324 do not apply, a reissue application is the appropriate vehicle to correct inventorship. The failure to name the correct inventive entity is an error in the patent which is correctable under 35 U.S.C. 251. The reissue oath or declaration pursuant to 37 CFR 1.175 must state that the applicant believes the original patent to be wholly or partly inoperative or invalid through error of a person being incorrectly named in an issued patent as the inventor, or through error of an inventor incorrectly not named in an issued patent, and, for applications filed before September 16, 2012, must also state that such error arose without any deceptive intention on the part of the applicant. The reissue oath or declaration must, as stated in 37 CFR 1.175, also comply with one of 37 CFR 1.63, 1.64, or 1.67 if the reissue application is filed on or after September 16, 2012, or comply with pre-AIA 37 CFR 1.63 if filed before September 16, 2012.

The reissue application with its reissue oath or declaration under 37 CFR 1.175 provides a complete mechanism to correct inventorship. See A.F. Stoddard & Co. v. Dann, 564 F.2d at 567, 195 USPQ at 106. A request under 37 CFR 1.48 or a petition under 37 CFR 1.324 cannot be used to correct the inventorship of a reissue application. If a request under 37 CFR 1.48 or a petition under 37 CFR 1.324 is filed in a reissue application, the request or petition should be dismissed and the processing or petition fee refunded. The material submitted with the request or petition should then be considered to determine if it complies with 37 CFR 1.175. If the material submitted with the request or petition does comply with the requirements of 37 CFR 1.175 (and the reissue application is otherwise in order), the correction of inventorship will be permitted as a correction of an error in the patent under 35 U.S.C. 251.

The correction of inventorship does not enlarge the scope of the patent claims. Where a reissue application does not seek to enlarge the scope of the claims of the original patent, the reissue oath may be made and sworn to, or the declaration made, by the assignee of the entire interest under 37 CFR 1.172. An assignee of part interest may not file a reissue application to correct inventorship where the other co-owner did not join in the reissue application and has not consented to the reissue proceeding. See Baker Hughes Inc. v. Kirk, 921 F.Supp. 801, 809, 38 USPQ2d 1885, 1892 (D.D.C. 1995). See 35 U.S.C. 251. On the other hand, an assignee of the entire interest can consent to and sign the reissue oath/declarationthat adds or deletes the name of an inventor by reissue (e.g., correct inventorship from inventor A to inventors A and B) without the original inventor’s consent. Thus, the assignee of the entire interest can file a reissue to change the inventorship to one which the assignee believes to be correct, even though an inventor might disagree. The protection of the assignee’s property rights in the application and patent are statutorily based in 35 U.S.C. 118. For additional information pertaining to the right of an assignee to take action, see MPEP § 324 (for applications filed before September 16, 2012) and § 325 (for applications filed on or after September 16, 2012). Where the name of an inventor X is to be deleted in a reissue application to correct inventorship in a patent, and inventor X has not assigned his/her rights to the patent, inventor X has an ownership interest in the patent. Inventor X must consent to the reissue (37 CFR 1.172(a)), even though inventor X’s name is being deleted as an inventor. If X’s name is being deleted as an inventor, X consents to the reissue application, and the remaining inventors sign the reissue oath or declaration, X need not sign. If, however, an assignee signs the reissue oath or declaration, inventor X’s signature must also be included in the reissue oath or declaration as an assignee.

1412.05   Correction of Inventorship in a Broadening Reissue Application [R-11.2013]

I.   Reissue Application Filed On or After September 16, 2012

[Editor Note: See subsection II., below, for reissue applications filed before September 16, 2012.]

Where a reissue application to correct inventorship is filed on or after September 16, 2012, and the application for the original patent was filed under 37 CFR 1.46 by the assignee of the entire interest, the assignee may sign the inventor’s oath or declaration even where the application also seeks to enlarge the scope of the claims of the original patent. If the application for the original patent was not filed under 37 CFR 1.46 by the assignee of the entire interest, then the signature of all of the inventors is needed on the oath or declaration except as provided for in 37 CFR 1.64. Note that under 37 CFR 1.64, the assignee of the entire interest may sign a substitute statement where the inventor is deceased, legally incapacitated, refuses to execute the reissue oath or declaration, or cannot be found or reached after diligent effort. See MPEP § 604.

In situations where a reissue application seeks to correct inventorship in the patent and the inventors sign the reissue oath or declaration for a broadening reissue application, the correct inventive entity must sign the reissue oath or declaration. . If an inventor is being deleted in a reissue application to correct inventorship in a patent and the inventors are required to sign the oath or declaration, the inventor being deleted need not sign the reissue oath or declaration. For example, a reissue application is filed to correct inventorship from inventors A, B, and C (listed as inventors on the patent) to inventors A and B. Inventor C is being deleted as a named inventor. In such a case, A and B are the correct inventors, and accordingly, (in situations where the assignee is not permitted to sign) inventors A and B must sign the reissue oath or declaration but inventor C need not sign the reissue oath or declaration.

If an inventor is being deleted in a reissue application to correct inventorship in a patent and the inventors are required to sign the oath or declaration, the inventor being deleted need not sign the reissue oath or declaration. For example, a reissue application is filed to correct inventorship from inventors A, B, and C (listed as inventors on the patent) to inventors A and B. Inventor C is being deleted as a named inventor. In such a case, A and B are the correct inventors, and accordingly, (in situations where the assignee is not permitted to sign) inventors A and B must sign the reissue oath or declaration but inventor C need not sign the reissue oath or declaration.

If an inventor is being added in a reissue application to correct inventorship in a patent, the inventor being added must sign the reissue oath or declaration together with the inventors previously designated on the patent. For example, a reissue application is filed to correct the inventorship from inventors A and B (listed as inventors on the patent) to inventors A, B, and C. Inventor C is the inventor being added. In such a case, A, B, and C are the correct inventors, and accordingly, each of A, B, and C must sign the reissue oath or declaration. If inventor C refuses to sign, the assignee of the entire interest may sign a substitute statement under 37 CFR 1.64. Thus, even where an application changes the claims to enlarge the scope of the patent claims in addition to the inventorship change, and the application for the original patent was not filed under 37 CFR 1.46 by the assignee of the entire interest, the assignee can add an inventor who refuses to sign by making use of 37 CFR 1.64.

II.   Reissue Application Filed Before September 16, 2012

[Editor Note: See subsection I., above, for reissue applications filed on or after September 16, 2012.]

Where a reissue application to correct inventorship is filed before September 16, 2012, and that application also changes the claims to enlarge the scope of the patent claims, the signature of all the inventors is needed. However, if an inventor refuses to sign the reissue oath or declaration because he or she believes the change in inventorship (to be effected) is not correct, the reissue application can still be filed with a petition under pre-AIA 37 CFR 1.47 without that inventor’s signature, provided the written consent of all owners/assignees as required by pre-AIA 37 CFR 1.172(a) is also submitted. Compare, however, the situation where a patent to inventors X and Y has no assignee, a reissue application is filed by inventor Y to delete the name of inventor X as an inventor and to broaden the patent. Inventor X refuses to sign the reissue oath or declaration and refuses to provide the consent as required by pre-AIA 37 CFR 1.172(a). In this instance, a pre-AIA 37 CFR 1.47 petition would not be appropriate to permit the filing of the reissue application because the consent requirement of pre-AIA 37 CFR 1.172(a) for each owner/assignee is not met. Resort to the courts would be required to delete the name of inventor X as an inventor where X will not consent to the filing of a reissue application. As stated in the second paragraph of pre-AIA 35 U.S.C. 256, “[t]he court before which such matter is called in question may order correction of the patent on notice and hearing of all parties concerned and the Director shall issue a certificate accordingly.”
