Maintenance fees coming due

Monolithic 3D Inc.

67 maintenance fees come due in the 12 months from Nov 14, 2026, the next on Nov 14, 2026. Unpaid by May 14, 2027, that one lapses early.

A maintenance fee does not end a patent on its due date. It falls due at 3.5, 7.5 and 11.5 years from grant, and the patent lapses only if the fee is still unpaid at the end of the six month grace period that follows.
