Maintenance fees coming due

Switchback Systems, Inc.

1 maintenance fee comes due on Sep 24, 2027, in the 12 months from Nov 14, 2026. Unpaid by Mar 24, 2028, 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.
