Q: After I buy the trademark, can the owner still authorize the trademark to be used by others? Answer: Trademark transfer is an act by which the trademark registrant transfers the exclusive right to use the trademark to another party in accordance with legal procedures during the validity period of the registered trademark. Trademark transfer generally takes the following forms: contractual transfer, inheritance transfer, and transfer due to administrative orders. Once a trademark is transferred, the original owner loses ownership and therefore has no right to authorize others to use it.
