2575 Notices
MPEP SECTION SUMMARY
The Office has no duty to notify patentees when their maintenance fees are due. However, they try to send out a reminder notice during the grace period. Notices provided by the Office should merely be thought of as a courteous reminder attempt, the Office is not required to send anything at all.
It is always the patentee’s responsibility to pay the maintenance fee on time, the failure to receive the reminder notice will never shift the burden to the Office. A notice will appear in the Official Gazette indicating which patents are up for maintenance fees.
