Grace period

PubliƩ le 26 August 2025

The grace period in intellectual property law refers to a period during which the holder of a right (e.g., a trademark or patent) can still regularise a legal situation after the expiration of a legal deadline without losing their rights. This concept is particularly useful in several situations, including trademark renewal and patent maintenance.

Key aspects of the grace period:

  • Trademark renewal: In the case of trademarks, the grace period allows the owner to renew the registration of their trademark after the initial protection period, generally 10 years, has expired without losing their rights. The grace period is often 6 months from the expiration date and involves a surcharge.
  • Payment of patent annuities: For patents, the grace period may apply to annual maintenance fees. If these fees are not paid on time, the patentee has an additional period, generally six months, to pay them, usually with a surcharge.
  • Effects of the grace period: During this period, IP rights remain in force. However, if the holder does not act before the expiry of this grace period, they risk losing their rights permanently.
  • Purpose: The grace period is intended to provide legal certainty to the holder, preventing a simple oversight or administrative delay from leading to the irreversible loss of rights.

In summary, the grace period in intellectual property law is an additional period allowing the holder to maintain or renew their rights despite exceeding the initial official deadline, by regularising the situation before the final expiry of this period.
