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 25, 2027The maintenance fee for Radiation detection device with improved illumination range having a photodetector that operates in two detecting modes (US 9,116,040) comes due Feb 25, 2027. Unpaid by Aug 25, 2027, it lapses early.
- 1 fee due Sep 22, 2027The maintenance fee for Detection circuit with anti-blooming circuit (US 9,291,498) comes due Sep 22, 2027. Unpaid by Mar 22, 2028, it lapses early.
