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 22, 2027The maintenance fee for Polymer solid electrolytes, methods of making, and electrochemical cells comprising the same (US 11,735,770) comes due Feb 22, 2027. Unpaid by Aug 23, 2027, it lapses early.
- 1 fee due Apr 30, 2027The maintenance fee for Electrodes for lithium-ion batteries and other (US 11,804,603) comes due Apr 30, 2027. Unpaid by Nov 1, 2027, it lapses early.
- 1 fee due Oct 23, 2027The maintenance fee for Electrolytes for high-voltage cathode materials and other applications (US 11,967,675) comes due Oct 23, 2027. Unpaid by Apr 24, 2028, it lapses early.
