RIGHT IN TRADEMARK ONCE RELINQUISHED CANNOT BE CLAIMED UNLESS TERMS OF RELINQUISHMENT REVOKED: DELHI HIGH COURT The Delhi High Court in the case of Ampa Cycles Private Limited vs. Jagmohan Ratra has held that once a person expressly relinquishes the rights to a trademark, the same cannot be claimed again, unless the terms of the dissolution deed are novated or revoked. Additionally, if the rights to a trademark have been relinquished to a third party, the relinquisher cannot restrain the assignee from exercising their rights over that trademark.
