The case of In re Oguie is significant in patent disclaimer cases, particularly those involving failure to present claims for interference. According to MPEP 2304.04(c) , both Form Paragraphs 7.48.aia and 7.48.fti cite this case: “This amounts to a concession that, as a matter of law, the patentee is the first inventor in this country. See In re Oguie, 517 F.2d 1382, 186 USPQ 227 (CCPA 1975).” The In re Oguie case established the legal principle that failure to engage in interference proceedings when notified amounts to a disclaimer of the subject matter. This case is used as a legal basis for rejecting claims when an applicant fails to present claims or take necessary steps for interference after being notified of potentially interfering subject matter.
