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 15, 2027The maintenance fee for Lithium doped silicon oxide-based negative electrode material and method of manufacturing the same (US 11,728,479) comes due Feb 15, 2027. Unpaid by Aug 16, 2027, it lapses early.
- 1 fee due Apr 1, 2027The maintenance fee for Li-containing silicon oxide powder and production method thereof (US 10,427,943) comes due Apr 1, 2027. Unpaid by Oct 1, 2027, it lapses early.
- 1 fee due May 14, 2027The maintenance fee for Method for producing silicon oxide powder and negative electrode material (US 11,817,581) comes due May 14, 2027. Unpaid by Nov 15, 2027, it lapses early.
