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 Feb 11, 2027The maintenance fee for Spread-spectrum phase locked loop circuit and method (US 9,106,236) comes due Feb 11, 2027. Unpaid by Aug 11, 2027, it lapses early.
- 1 fee due Apr 27, 2027The maintenance fee for Crystal oscillator circuit having low power consumption, low jitter and wide operating range (US 9,172,327) comes due Apr 27, 2027. Unpaid by Oct 27, 2027, it lapses early.
- 2 fees due Sep 3 to 15, 2027 · next Sep 3
