§ 133.15 - Term of CBP trade name recordation.
Protection for a recorded trade name shall remain in force as long as the trade name is used. The recordation shall be canceled upon request of the recordant or upon evidence of disuse. From time to time, the IPR & Restricted Merchandise Branch may request the trade name owner to advise whether the name is still in use. The failure of a trade name owner to respond to such a request shall be regarded as evidence of disuse.
