1403    Diligence in Filing [R-11.2013]

When a reissue application is filed within 2 years from the date of the original patent, a rejection on the grounds of lack of diligence or delay in filing the reissue should not normally be made. Ex parte Lafferty, 190 USPQ 202 (Bd. App. 1975); but see Rohm & Haas Co. v.Roberts Chemical Inc., 142 F. Supp. 499, 110 USPQ 93 (S.W. Va. 1956), rev’d on other grounds, 245 F.2d 693, 113 USPQ 423 (4th Cir. 1957).

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) corresponds to the provisions of pre-AIA 35 U.S.C. 251, fourth paragraph

Where any broadening reissue application is filed within two years from the date of the original patent, 35 U.S.C. 251 presumes diligence, and the examiner should not inquire why applicant failed to file the reissue application earlier within the two year period.

See MPEP § 1412.03 for broadening reissue practice. See also In re Graff, 111 F.3rd 874, 42 USPQ2d 1471 (Fed. Cir. 1997); In re Bennett, 766 F.2d 524, 528, 226 USPQ 413, 416 (Fed. Cir. 1985); In re Fotland, 779 F.2d 31, 228 USPQ 193 (Fed. Cir. 1985).

A reissue application that is filed on the 2-year anniversary date of the patent grant is considered as being filed within 2 years. See Switzer v. Sockman, 333 F.2d 935, 142 USPQ 226 (CCPA 1964) (a similar rule in interferences).

A reissue application can be granted a filing date without an oath or declaration, or without the basic filing fee, search fee, or examination fee being present. See 37 CFR 1.53(f). Applicant will be given a period of time to provide the missing parts and to pay the surcharge under 37 CFR 1.16(f). See MPEP § 1410.01.
