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.
- 2 fees due Aug 6 to 13, 2027 · next Aug 6
- 1 fee due Sep 19, 2027The maintenance fee for Method, apparatus, terminal and storage medium for quantum topology graph optimization (US 11,934,919) comes due Sep 19, 2027. Unpaid by Mar 20, 2028, it lapses early.
- 1 fee due Oct 23, 2027The maintenance fee for Method and apparatus for constructing quantum circuit corresponding to linear function (US 11,966,815) comes due Oct 23, 2027. Unpaid by Apr 24, 2028, it lapses early.
