Intervention

Anyone, other than the proprietor, who claims to have an interest in a registered trade mark may apply to become involved (in legal words 'intervene’) in post registration legal actions. These actions could be invalidation, revocation or rectification proceedings.

Who can have an interest in a registered trade mark?

This usually means:

  • a subsidiary or related company of the proprietor or licensee of the proprietor who uses the mark itself; or
  • a new owner of the trade mark who has not yet recorded their ownership in the register.

How do I apply to intervene?

You should consider getting professional advice before you decide anything.

You should send us:

  • a Form TM27 PDF document(33Kb) 'Application to intervene in proceedings’ and
  • a statement of your reasons for making the application

What does it cost?

You do not have to pay any fee for sending us Form TM27.

When can I intervene?

There is no time limit for sending us your application, but ideally, you should do so as soon as you know about the legal proceedings.
