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 23, 2027
The maintenance fee for Modular stretchable and flexible capacitance sensors for use with electrical capacitance volume tomography and capacitance sensing applications (US 10,359,386) comes due Jan 23, 2027. Unpaid by Jul 23, 2027, it lapses early.
1 fee due Feb 18, 2027
