How long does a trademark last?

Senior Trademark Attorney

A trademark can last indefinitely, provided it is renewed every 10 years and remains in genuine commercial use.

Failure to renew within the grace period (typically six months after expiry) causes the trademark to lapse. Failure to use the mark for a continuous period of five years can give third parties grounds to apply for cancellation. In the US, an additional Declaration of Use must be filed between the 5th and 6th year after registration.
