Yes, a patent can be reinstated after expiration due to non-payment of maintenance fees under certain conditions. The MPEP 2590 outlines the process for patent reinstatement:

“The patent may be reinstated if the delay in payment of the maintenance fee was unintentional.”

Key points about patent reinstatement:

  • A petition for reinstatement must be filed within 24 months from the expiration date.
  • The petition must include a statement that the delay was unintentional.
  • All required maintenance fees and any applicable surcharges must be paid.
  • The Director of the USPTO must determine that the delay was indeed unintentional.

It’s important to note that the reinstatement process is not automatic and requires a formal petition and fee payment.
