Trademark Co-Existence Agreement Template
An agreement between two parties agreeing that they will allow each other’s trademarks to co-exist, both within the USPTO trademark registration database, and in the real world. Similar to a Trademark Consent Letter, but more two-sided, and with a much broader scope.
If your trademark application is refused by the USPTO because of a likelihood of confusion with an existing trademark registration, you can try to get the owner of that existing trademark registration to agree to sign this, along with you. You can then submit it to the USPTO when you respond to your office action, and the USPTO will weigh it heavily when re-evaluating your trademark application, greatly increasing your chances of reaching registration.
