Under pre-AIA 35 U.S.C. 102(c), abandonment of the “invention” (as distinguished from abandonment of an application) results in loss of right to a patent.

“Actual abandonment under pre-AIA 35 U.S.C. 102(c) requires that the inventor intend to abandon the invention, and intent can be implied from the inventor’s conduct with respect to the invention. In re Gibbs, 437 F.2d 486, 168 USPQ 578 (CCPA 1971). Such intent to abandon the invention will not be imputed, and every reasonable doubt should be resolved in favor of the inventor.” Ex parte Dunne, 20 USPQ2d 1479 (Bd. Pat. App. & Inter. 1991).

Abandonment under pre-AIA 35 U.S.C. 102(c) requires a deliberate, though not necessarily express, surrender of any rights to a patent. To abandon the invention the inventor must intend a dedication to the public. Such dedication may be either express or implied, by actions or inactions of the inventor. U.S. Rifle & Cartridge Co. v. Whitney Arms Co., 118 U.S. 22, 25 (1886); Consolidated Fruit–Jar Co. v. Wright, 94 U.S. 92, 96 (1876). Delay alone is not sufficient to infer the requisite intent to abandon. Lovell v. Peer, 148 F.2d 212, 214, 65 USPQ 127, 129 (CCPA 1945). See also Moore v. United States, 194 USPQ 423, 428 (Ct. Cl. 1977) (The drafting and retention in his own files of two patent applications by inventor indicates an intent to retain his invention; delay in filing the applications was not sufficient to establish abandonment); but see Davis Harvester Co., Inc. v. Long Mfg. Co., 252 F. Supp. 989, 1009-10, 149 USPQ 420, 435-436 (E.D. N.C. 1966) (Where the inventor does nothing over a period of time to develop or patent his invention, ridicules the attempts of another to develop that invention and begins to show active interest in promoting and developing his invention only after successful marketing by another of a device embodying that invention, the inventor has abandoned his invention under pre-AIA 35 U.S.C. 102(c).).

Where there is no evidence of expressed intent or conduct by inventor to abandon the invention, delay in reapplying for patent after abandonment of a previous application does not constitute abandonment under pre-AIA 35 U.S.C. 102(c). Petersen v. Fee Int’l, Ltd., 381 F. Supp. 1071, 182 USPQ 264 (W.D. Okla. 1974).

Any inference of abandonment (i.e., intent to dedicate to the public) of subject matter disclosed but not claimed in a previously issued patent is rebuttable by an application filed at any time before a statutory bar arises. Accordingly, a rejection of a claim of a patent application under pre-AIA 35 U.S.C. 102(c) predicated solely on the issuance of a patent which discloses the subject matter of the claim in the application without claiming it would be improper, regardless of whether there is copendency between the application at issue and the application which issued as the patent. In re Gibbs, 437 F.2d 486, 168 USPQ 578 (CCPA 1971).

The mere lapse of time will not bar a patent. The only exception is when there is a priority contest under pre-AIA 35 U.S.C. 102(g) and applicant abandons, suppresses or conceals the invention. Panduit Corp. v. Dennison Mfg. Co., 774 F.2d 1082, 1101, 227 USPQ 337, 350 (Fed. Cir. 1985). Abandonment, suppression and concealment are treated by the courts under pre-AIA 35 U.S.C. 102(g).
