Do patents expire if not used?
Asked by: Miss Skyla Beer | Last update: February 19, 2026Score: 4.2/5 (49 votes)
Yes, patents expire, but primarily due to reaching their time limit (typically 20 years for utility patents from filing date) or by the owner failing to pay required maintenance fees, not simply because they aren't used, though inactivity can lead to abandonment if other conditions aren't met. While a patent grants exclusive rights, it's the payment of fees that keeps it active for its full term; missing these fees causes it to lapse, making the invention public domain sooner.
