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 Apr 30, 2027The maintenance fee for Coupling alignment device and method for laser chip and silicon-based optoelectronic chip (US 11,803,019) comes due Apr 30, 2027. Unpaid by Nov 1, 2027, it lapses early.
- 1 fee due Jun 5, 2027The maintenance fee for Wafer-level manufacturing process of a flexible integrated array sensor (US 11,839,160) comes due Jun 5, 2027. Unpaid by Dec 6, 2027, it lapses early.
