Chemocentryx, Inc.

50 maintenance fees come due in the 12 months from Nov 15, 2026, the next on Dec 25, 2026. Unpaid by Jun 25, 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.
