What is the time frame related to a 102(b) rejection regarding public use or sale?

The time frame related to a 102(b) rejection regarding public use or sale is indeed more than one year before the filing date. This is rooted in the provisions of U.S. patent law, specifically 35 U.S.C. § 102(b), which establishes that an inventor may not obtain a patent if the invention was publicly used or on sale more than one year prior to the filing of the patent application.

This one-year grace period serves as a protective measure for inventors, ensuring they have sufficient time to evaluate their invention and its market potential without the risk of losing patent rights prematurely. If an invention is disclosed to the public or placed on sale over a year before the patent application is filed, the invention is considered prior art against the patent application, which can lead to a rejection.

Other time frames mentioned in the options do not align with the legal framework established for 102(b) rejections. Thus, the understanding of this specific time frame is crucial for inventors to navigate patent applications successfully.
