38 CFR § 1.660
Expeditious handling
November 5, 2020
No patent may be granted where the invention has been in public use or publicly disclosed for more than one year before filing of a patent application. Hence, submissions involving inventions should be made as promptly as possible in order to avoid delay which might jeopardize title to the invention or impair the rights of the inventor or the Government.
