Which scenario falls under 102(b) for prior art considerations?

The scenario that aligns with Section 102(b) of the Patent Act involves public use in the U.S. more than one year before the filing date. Under 102(b), an invention is considered prior art if it was publicly used or known in the United States at least one year before the effective filing date of the patent application. This one-year grace period is a significant aspect of U.S. patent law, where an inventor has time to assess the invention's market viability before applying for a patent.

In this instance, the public use occurring in the U.S. more than a year prior to filing directly renders the invention unpatentable due to the public's access to the information. The one year is critical, as it marks the cutoff for any prior public use or knowledge of the invention.

The other scenarios do not meet the specific criteria outlined in 102(b). For example, a publication anywhere in the world before filing does not apply because 102(b) specifically addresses activities that occur within the U.S. The notion of public knowledge at the time of filing does not fit as it focuses on knowledge existing at the time of patent filing rather than its status before the one-year bar. Additionally, foreign filings within one year of U
