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 Mar 22, 2027
The maintenance fee for High power ultraviolet light emitting diode with superlattice (US 9,142,714) comes due Mar 22, 2027. Unpaid by Sep 22, 2027, it lapses early.
