Monitoring competitor patents for lapses is a core competitive intelligence activity. When a rival's patent lapses, you gain freedom to operate in that technology space — but only if you know about it quickly enough to act.
Identify the patents most relevant to your technology space. Search USPTO Patent Center by assignee name, technology class (CPC/IPC), or keyword. Focus on patents that currently block your product roadmap or that cover core competitor technology.
US utility patents have fee windows at 3.5, 7.5, and 11.5 years from grant. A patent that misses a window is at immediate risk of lapse. Manually tracking dozens of patents across three fee windows is error-prone — tools like PatentLapse automate this.
You want to know the moment a patent enters a fee window (increased lapse risk) and the moment it actually lapses. PatentLapse monitors USPTO bulk fee event data and sends email alerts within 24 hours of a status change on any watched patent.
When a competitor patent lapses: confirm the lapse via USPTO Patent Center, check for pending reinstatement petitions, assess freedom to operate with your patent counsel, then move on product or licensing strategy.
