Protecting Your Trademark Rights
You are responsible for enforcing your rights if you receive a registration, because the USPTO does not “police” the use of marks. While the USPTO attempts to ensure that no other party receives a federal registration for an identical or similar mark for or as applied to related goods/services, the owner of a registration is responsible for bringing any legal action to stop a party from using an infringing mark. If a right holder suspects that a registered mark is being infringed upon or may be subject to future infringement, the registered mark can be recorded with U.S. Customs and Border Protection through its e-Recordation application.
