Shuaimei Suit Factory can apply to the Trademark Review and Adjudication Board of the State Trademark Office to revoke Tengda Company’s registered trademark. The reasons are as follows: the two trademarks differ only by one word, and have similar character combinations and pronunciations. They constitute similar trademarks and use the same type of goods. In order to fully protect the interests of enterprises and consumers, in accordance with the Trademark Law 》Article 27, Shuamei Suit Factory can, within one year from the date of approval and registration of Tengda Company’s trademark, lodge an objection with the National Trademark Office Review and Adjudication Committee and request the cancellation of Tengda Company’s trademark on the grounds that it is a similar trademark. Before the cancellation, because both trademarks were registered trademarks, Shuamei Suit Factory could not require Tenda Company to bear legal liability for trademark infringement. However, if the Trademark Review and Adjudication Board makes a final decision to cancel Tenda Company’s registered trademark, When Tenda Company continues to use the trademark, Shuamei Suit Factory can request handling from the industrial and commercial administration department at or above the county level, or directly file a lawsuit with the People's Court to hold Tenda Company legally responsible for trademark infringement.
