2137 35 U.S.C. 102(f) - 2100 Patentability
2137 35 U.S.C. 102(f)
35 U.S.C. 102 Conditions for patentability; novelty and loss of right to patent.
A person shall be entitled to a patent unless -
*****
(f) he did not himself invent the subject matter sought to be patented.
*****
Where it can be shown that an applicant "derived" an invention from another, a rejection under 35 U.S.C. 102(f) is proper. Ex parte Kusko, 215 USPQ 972, 974 (Bd. App. 1981) ("most, if not all, determinations under section 102(f) involve the question of whether one party derived an invention from another").
While derivation will bar the issuance of a patent to the deriver, a disclosure by the deriver, absent a bar under 35 U.S.C. 102(b), will not bar the issuance of a patent to the party from which the subject matter was derived. In re Costello, 717 F.2d 1346, 1349, 219 USPQ 389, 390-91 (Fed. Cir. 1983) ("[a] prior art reference that is not a statutory bar may be overcome by two generally recognized methods": an affidavit under 37 CFR 1.131, or an affidavit under 37 CFR 1.132 "showing that the relevant disclosure is a description of the applicant's own work"); In re Facius, 408 F.2d 1396, 1407, 161 USPQ 294, 302 (CCPA 1969) (subject matter incorporated into a patent that was brought to the attention of the patentee by applicant, and hence derived by the patentee from the applicant, is available for use against applicant unless applicant had actually invented the subject matter placed in the patent).
Where there is a published article identifying the authorship ( MPEP § 715.01(c)) or a patent identifying the inventorship ( MPEP § 715.01(a)) that discloses subject matter being claimed in an application undergoing examination, the designation of authorship or inventorship does not raise a presumption of inventorship with respect to the subject matter disclosed in the article or with respect to the subject matter disclosed but not claimed in the patent so as to justify a rejection under 35 U.S.C. 102(f). However, it is incumbent upon the inventors named in the application, in reply to an inquiry regarding the appropriate inventorship under subsection (f), or to rebut a rejection under 35 U.S.C. 102(a) or (e), to provide a satisfactory showing by way of affidavit under 37 CFR 1.132 that the inventorship of the application is correct in that the reference discloses subject matter invented by the applicant rather than derived from the author or patentee notwithstanding the authorship of the article or the inventorship of the patent. In re Katz, 687 F.2d 450, 455, 215 USPQ 14, 18 (CCPA 1982) (inquiry is appropriate to clarify any ambiguity created by an article regarding inventorship, and it is then incumbent upon the applicant to provide "a satisfactory showing that would lead to a reasonable conclusion that [applicant] is the.inventor" of the subject matter disclosed in the article and claimed in the application).
DERIVATION REQUIRES COMPLETE CONCEPTION BY ANOTHER AND COMMUNICATION TO THE ALLEGED DERIVER
"The mere fact that a claim recites the use of various components, each of which can be argumentatively assumed to be old, does not provide a proper basis for a rejection under 35 U.S.C. 102(f)." Ex parte Billottet, 192 USPQ 413, 415 (Bd. App. 1976). Derivation requires complete conception by another and communication of that conception by any means to the party charged with derivation prior to any date on which it can be shown that the one charged with derivation possessed knowledge of the invention. Kilbey v. Thiele, 199 USPQ 290, 294 (Bd. Pat. Inter. 1978).
See also Price v. Symsek, 988 F.2d 1187, 1190, 26 USPQ2d 1031, 1033 (Fed. Cir. 1993); Hedgewick v. Akers, 497 F.2d 905, 908, 182 USPQ 167, 169 (CCPA 1974). "Communication of a complete conception must be sufficient to enable one of ordinary skill in the art to construct and successfully operate the invention." Hedgewick, 497 F.2d at 908, 182 USPQ at 169. See also Gambro Lundia AB v. Baxter Healthcare Corp., 110 F.3d 1573, 1577, 42 USPQ2d 1378, 1383 (Fed. Cir. 1997) (Issue in proving derivation is "whether the communication enabled one of ordinary skill in the art to make the patented invention.").
PARTY ALLEGING DERIVATION DOES NOT HAVE TO PROVE AN ACTUAL REDUCTION TO PRACTICE, DERIVATION OF PUBLIC KNOWLEDGE, OR DERIVATION IN THIS COUNTRY
The party alleging derivation "need not prove an actual reduction to practice in order to show derivation." Scott v. Brandenburger, 216 USPQ 326, 327 (Bd. App. 1982). Furthermore, the application of subsection (f) is not limited to public knowledge derived from another, and "the site of derivation need not be in this country to bar a deriver from patenting the subject matter." Ex parte Andresen, 212 USPQ 100, 102 (Bd. App. 1981).
DERIVATION DISTINGUISHED FROM PRIORITY OF INVENTION
Although derivation and priority of invention both focus on inventorship, derivation addresses originality (i.e., who invented the subject matter), whereas priority focuses on which party first invented the subject matter. Price v. Symsek, 988 F.2d 1187, 1190, 26 USPQ2d 1031, 1033 (Fed. Cir. 1993).
35 U.S.C. 102(f) MAY APPLY WHERE 35 U.S.C. 102(a) AND 35 U.S.C. 102(e) ARE NOT AVAILABLE STATUTORY GROUNDS FOR REJECTION
35 U.S.C. 102(f) does not require an inquiry into the relative dates of a reference and the application, and therefore may be applicable where subsections (a) and (e) are not available for references having an effective date subsequent to the effective date of the application being examined. However for a reference having a date later than the date of the application some evidence may exist that the subject matter of the reference was derived from the applicant in view of the relative dates. Ex parte Kusko, 215 USPQ 972, 974 (Bd. App. 1981) (The relative dates of the events are important in determining derivation; a publication dated more than a year after applicant's filing date that merely lists as literary coauthors individuals other than applicant is not the strong evidence needed to rebut a declaration by the applicant that he is the sole inventor.).
