2135 35 U.S.C. 102(d)
35 U.S.C. 102 Conditions for patentability; novelty and loss of right to patent.
A person shall be entitled to a patent unless -
- (d) the invention was first patented or caused to be patented, or was the subject of an inventor’s certificate, by the applicant or his legal representatives or assigns in a foreign country prior to the date of the application for patent in this country on an application for patent or inventor’s certificate filed more than twelve months before the filing of the application in the United States.
GENERAL REQUIREMENTS OF 35 U.S.C. 102(d)
35 U.S.C. 102(d) establishes four conditions which, if all are present, establish a bar against the granting of a patent in this country:
- (A) The foreign application must be filed more than 12 months before the effective U.S. filing date (See MPEP § 706.02 regarding effective U.S. filing date of an application);
- (B) The foreign application must have been filed by the same applicant as in the United States or by his or her legal representatives or assigns.
- (C) The foreign patent or inventor’s certificate must be actually granted (e.g., by sealing of the papers in Great Britain) before the U.S. filing date. It need not be published.
- (D) The same invention must be involved.
If such a foreign patent or inventor’s certificate is discovered by the examiner, the rejection is made under 35 U.S.C. 102(d) on the ground of statutory bar. See MPEP § 2135.01 for further clarification of each of the four requirements of 35 U.S.C. 102(d).
2135.01 The Four Requirements of 35 U.S.C. 102(d)
I. FOREIGN APPLICATION MUST BE FILED MORE THAN 12 MONTHS BEFORE THE EFFECTIVE U.S. FILING DATE
A. An Anniversary Date Ending on a Weekend or Holiday Results in an Extension to the Next Business Day
The U.S. application is filed in time to prevent a 35 U.S.C. 102(d) bar from arising if it is filed on the 1 year anniversary date of the filing date of the foreign application. If this day is a Saturday, Sunday or Federal holiday, the year would be extended to the following business day. See Ex parte Olah, 131 USPQ 41 (Bd. App. 1960.) Despite changes to 37 CFR 1.6(a)(2) and 1.10, which require the PTO to accord a filing date to an application as of the date of deposit as “Express Mail” with the U.S. Postal Service in accordance with 37 CFR 1.10 (e.g., a Saturday filing date), the rule changes do not affect applicant’s concurrent right to defer the filing of an application until the next business day when the last day for “taking any action” falls on a Saturday, Sunday, or a Federal holiday (e.g., the last day of the 1-year grace period falls on a Saturday).
B. A Continuation-in-Part Breaks the Chain of Priority as to Foreign as Well as U.S. Parents
In the case where applicant files a foreign application, later files a U.S. application claiming priority based on the foreign application, and then files a continuation-in-part (CIP) application whose claims are not entitled to the filing date of the U.S. parent, the effective filing date is the filing date of the CIP and applicant cannot obtain the benefit of either the U.S. parent or foreign application filing dates. In re Van Langenhoven, 458 F.2d 132, 137, 173 USPQ 426, 429 (CCPA 1972). If the foreign application issues into a patent before the filing date of the CIP, it may be used in a 35 U.S.C. 102(d)/103 rejection if the subject matter added to the CIP does not render the claims nonobvious over the foreign patent. Ex parte Appeal No. 242-47, 196 USPQ 828 (Bd. App. 1976) (Foreign patent can be combined with other prior art to bar a U.S. patent in an obviousness rejection based on 35 U.S.C. 102(d)/103).
II. FOREIGN APPLICATION MUST HAVE BEEN FILED BY SAME APPLICANT, HIS OR HER LEGAL REPRESENTATIVE OR ASSIGNS
Note that where the U.S. application was made by two or more inventors, it is permissible for these inventors to claim priority from separate applications, each to one of the inventors or a subcombination of inventors. For instance, a U.S. application naming inventors A and B may be entitled to priority from one application to A and one to B filed in a foreign country.
III. THE FOREIGN PATENT OR INVENTOR’S CERTIFICATE WAS ACTUALLY GRANTED BEFORE THE U.S. FILING DATE
A. To Be “Patented” an Exclusionary Right Must Be Awarded to the Applicant
“Patented” means “a formal bestowal of patent rights from the sovereign to the applicant.” In re Monks, 588 F.2d 308, 310, 200 USPQ 129, 131 (CCPA 1978); American Infra-Red Radiant Co. v. Lambert Indus., 360 F.2d 977, 149 USPQ 722 (8th Cir.), cert. denied, 385 U.S. 920 (1966) (German Gebrauchsmuster petty patent was held to be a patent usable in a 35 U.S.C. 102(d) rejection. Gebrauchmustern are not examined and only grant a 6-year patent term. However, except as to duration, the exclusionary patent right granted is as extensive as in the U.S.).
B. A Published Application Is Not a “Patent”
An application must issue into a patent before it can be applied in a 35 U.S.C. 102(d) rejection. Ex parte Fujishiro, 199 USPQ 36 (Bd. App. 1977) (“Patenting,” within the meaning of 35 U.S.C. 102(d), does not occur upon laying open of a Japanese utility model application (kokai or kohyo)); Ex parte Links, 184 USPQ 429 (Bd. App. 1974) (German applications, which have not yet been published for opposition, are published in the form of printed documents called Offenlegungsschriften 18 months after filing. These applications are unexamined or in the process of being examined at the time of publication. The Board held that an Offenlegungsschrift is not a patent under 35 U.S.C. 102(d) even though some provisional rights are granted. The Board explained that the provisional rights are minimal and do not come into force if the application is withdrawn or refused.).
C. An Allowed Application Can Be a “Patent” for Purposes of 35 U.S.C. 102(d) as of the Date Published for Opposition Even Though It Has Not Yet Been Granted as a Patent
An examined application which has been allowed by the examiner and published to allow the public to oppose the grant of a patent has been held to be a “patent” for purposes of rejection under 35 U.S.C. 102(d) as of the date of publication for opposition if substantial provisional enforcement rights arise. Ex parte Beik, 161 USPQ 795 (Bd. App. 1968) (This case dealt with examined German applications. After a determination that an application is allowable, the application is published in the form of a printed document called an Auslegeschrift. The publication begins a period of opposition were the public can present evidence showing unpatentability. Provisional patent rights are granted which are substantially the same as those available once the opposition period is over and the patent is granted. The Board found that an Auslegeschrift provides the legal effect of a patent for purposes of rejection under 35 U.S.C. 102(d).).
D. Grant Occurs When Patent Becomes Enforceable
The critical date of a foreign patent as a reference under 35 U.S.C. 102(d) is the date the patent becomes enforceable (issued, sealed or granted). In re Monks, 588 F.2d 308, 310, 200 USPQ 129, 131 (CCPA 1978) (British reference became available as prior art on date the patent was “sealed” because as of this date applicant had the right to exclude others from making, using or selling the claimed invention.).
E. 35 U.S.C. 102(d) Applies as of Grant Date Even If There Is a Period of Secrecy After Patent Grant
A period of secrecy after granting the patent, as in Belgium and Spain, has been held to have no effect in connection with 35 U.S.C. 102(d). These patents are usable in rejections under 35 U.S.C. 102(d) as of the date patent rights are granted. In re Kathawala, 9 F.3d 942, 28 USPQ2d 1789 (Fed. Cir. 1993) (An invention is “patented” for purposes of 35 U.S.C. 102(d) when the patentee’s rights under the patent become fixed. The fact that applicant’s Spanish application was not published until after the U.S. filing date is immaterial since the Spanish patent was granted before U.S. filing.); Gramme Elec. Co. v. Arnoux and Hochhausen Elec. Co., 17 F. 838, 1883 C.D. 418 (S.D.N.Y. 1883) (Rejection made under a predecessor of 35 U.S.C. 102(d) based on an Austrian patent granted an exclusionary right for 1 year but was kept secret, at the option of the patentee, for that period. The court held that the Austrian patent grant date was the relevant date under the statute for purposes of 35 U.S.C. 102(d) but that the patent could not have been used to in a rejection under 35 U.S.C. 102(a) or (b).); In re Talbott, 443 F.2d 1397, 170 USPQ 281 (CCPA 1971) (Applicant cannot avoid a 35 U.S.C. 102(d) rejection by exercising an option to keep the subject matter of a German Gebrauchsmuster (petty patent) in secrecy until time of U.S. filing.).
IV. THE SAME INVENTION MUST BE INVOLVED
“Same Invention” Means That the Application Claims Could Have Been Presented in the Foreign Patent
Under 35 U.S.C. 102(d), the “invention... patented” in the foreign country must be the same as the invention sought to be patented in the U.S. When the foreign patent contains the same claims as the U.S. application, there is no question that “the invention was first patented... in a foreign country.” In re Kathawala, 9 F.3d 942, 945, 28 USPQ2d 1785, 1787 (Fed. Cir. 1993). However, the claims need not be identical or even within the same statutory class. If applicant is granted a foreign patent which fully discloses the invention and which gives applicant a number of different claiming options in the U.S., the reference in 35 U.S.C. 102(d) to “‘invention... patented’ necessarily includes all the disclosed aspects of the invention. Thus, the section 102(d) bar applies regardless whether the foreign patent contains claims to less than all aspects of the invention.” 9 F.3d at 946, 28 USPQ2d at 1788. In essence, a 35 U.S.C. 102(d) rejection applies if applicant’s foreign application supports the subject matter of the U.S. claims. In re Kathawala, 9 F.3d 942, 28 USPQ2d 1785 (Fed. Cir. 1993) (Applicant was granted a Spanish patent claiming a method of making a composition. The patent disclosed compounds, methods of use and processes of making the compounds. After the Spanish patent was granted, the applicant filed a U.S. application with claims directed to the compound but not the process of making it. The Federal Circuit held that it did not matter that the claims in the U.S. application were directed to the composition instead of the process because the foreign specification would have supported claims to the composition. It was immaterial that the formulations were unpatentable pharmaceutical compositions in Spain.).
