Understanding Public-Use Proceeding in Patent Law

Definition & Meaning

A public-use proceeding is a legal process in patent law that investigates whether a patent application should be denied because the invention was publicly used or sold more than one year before the application was submitted. This process is initiated by a petition from an individual or entity challenging the patent application. If the petition provides sufficient evidence, a hearing is conducted by a patent examiner, who will then issue a final decision that cannot be appealed.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A company publicly demonstrates a new technology at a trade show in January 2022 and files a patent application in March 2023. A competitor files a petition claiming the technology was publicly used, initiating a public-use proceeding.

Example 2: An inventor sells a prototype of their invention in December 2021 and later applies for a patent in February 2023. A third party challenges the patent application based on the prior sale, prompting a public-use proceeding. (hypothetical example)
