Legal analysis: If it is declared invalid by the Trademark Office, the trademark owner shall file an application for reexamination of trademark invalidation with the Trademark Review and Adjudication Board within 15 days after receiving the notice, and the Trademark Review and Adjudication Board will make a fair judgment. If the trademark is still declared invalid, it will make a decision. The last chance is to bring a lawsuit to the people's court within 30 days from the date of receiving the notice. If the trademark was originally declared invalid by the Trademark Review and Adjudication Board, then after receiving the Notice of Defense within the time limit of the Trademark Review and Adjudication Board, collect data and evidence to prove that the trademark was declared invalid within the specified time.

Legal basis: Amendment to the Criminal Law of People's Republic of China (PRC) (XVII). Article 213 of the Criminal Law is amended as: "Whoever uses the same trademark as its registered trademark on the same kind of goods or services without the permission of the registered trademark owner, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years and shall also or only be fined; If the circumstances are particularly serious, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years and fined.
