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 Jan 14, 2027The maintenance fee for Vertical insulated-gate turn-off device having a planar gate (US 9,082,648) comes due Jan 14, 2027. Unpaid by Jul 14, 2027, it lapses early.
- 1 fee due Mar 12, 2027The maintenance fee for Anti-parallel diode formed using damaged crystal structure in a vertical power device (US 11,757,017) comes due Mar 12, 2027. Unpaid by Sep 13, 2027, it lapses early.
- 1 fee due May 21, 2027The maintenance fee for Insulated trench gates with dopants implanted through gate oxide (US 11,824,092) comes due May 21, 2027. Unpaid by Nov 22, 2027, it lapses early.
- 1 fee due Aug 27, 2027The maintenance fee for Etch stop layer for injecting carriers into drift layer for a vertical power device (US 11,916,138) comes due Aug 27, 2027. Unpaid by Feb 28, 2028, it lapses early.
- 1 fee due Sep 24, 2027The maintenance fee for Vertical bidirectional insulated gate turn-off device (US 10,600,898) comes due Sep 24, 2027. Unpaid by Mar 24, 2028, it lapses early.
- 1 fee due Oct 5, 2027The maintenance fee for Dual depth trench-gated mos-controlled thyristor with well-defined turn-on characteristics (US 9,306,048) comes due Oct 5, 2027. Unpaid by Apr 5, 2028, it lapses early.
