One-year rule

Term · Law · MLC-T-LAW-003552

A patent rule under which an inventor keeps the right to a patent only by filing within one year after the invention was first publicly disclosed, sold or offered for sale by the inventor. The one-year period is the grace period in 35 U.S.C. section 102(b)(1) for the inventor's own disclosures. Many other countries apply stricter absolute novelty rules, so an early disclosure can destroy foreign patent rights at once.
