Under which condition may a person be denied a patent according to 35 U.S.C. § 102(f)?

The condition under which a person may be denied a patent according to 35 U.S.C. § 102(f) is when the applicant did not himself invent the subject matter sought to be patented. This section of the law establishes that only the true inventor or inventors can file for a patent on an invention. If the applicant claims to be the inventor but is not—perhaps because the invention was made by another individual who did not assign their rights—the patent application will be denied. This principle is crucial in maintaining the integrity of the patent system, as patents are intended to reward and recognize the actual inventors for their contributions to innovation.

Other options, while potentially relevant to patentability, do not directly pertain to the stipulations set forth in 35 U.S.C. § 102(f). For example, lack of novelty and public disclosure are covered under different sections, specifically concerning the criteria for patentability rather than the identity of the inventor. Documentation issues may relate to the requirements for filing a patent application but do not pertain to the inventor's right to apply. Thus, the emphasis on the true inventor is a fundamental aspect of patent law reflected in this section.
