Maintenance fees coming due

Step Pharma S.A.S.

1 maintenance fee comes due on Nov 23, 2026, in the 12 months from Nov 15, 2026. Unpaid by May 24, 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.
