Validity of utility models

The registration of a utility model is valid for four years from the filing date of the application. At the end of this period, you must renew the registration by paying a renewal fee.

Renew your utility model registration

You can renew the registration twice: first, for four years and after that for another two years. This means the maximum term of protection is 10 years from the filing date of the application.

Invalidate a utility model

Anyone can try to invalidate a utility model by lodging an invalidity claim against it. If we accept the invalidity claim, we will remove the utility model from the register. Read more about invalidation.
