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, 2027The maintenance fee for Articulating wave energy conversion system using a compound lever-arm barge (US 10,359,023) comes due Jan 23, 2027. Unpaid by Jul 23, 2027, it lapses early.
- 1 fee due Jun 17, 2027The maintenance fee for Hinge system for an articulated wave energy conversion system (US 10,508,640) comes due Jun 17, 2027. Unpaid by Dec 17, 2027, it lapses early.
- 1 fee due Nov 10, 2027The maintenance fee for Remotely reconfigurable high pressure fluid passive control system for controlling bi-directional piston pumps as active sources of high pressure fluid, as inactive rigid structural members or as isolated free motion devices (US 9,334,860) comes due Nov 10, 2027. Unpaid by May 10, 2028, it lapses early.
