Fee deadlines
Maintenance fees fall due 3.5, 7.5 and 11.5 years after grant. A missed fee ends a patent at the end of the six month grace period that follows, not on the due date.
- 1 fee due Dec 18, 2026The maintenance fee for Power network reduction and simulation in time and frequency domains to calculate voltage drop (US 10,325,047) comes due Dec 18, 2026. Unpaid by Jun 21, 2027, it lapses early.
- 1 fee due Mar 15, 2027The maintenance fee for Verification-based access to features in a business context-based social network (US 9,135,601) comes due Mar 15, 2027. Unpaid by Sep 15, 2027, it lapses early.
