Trademark objection and trademark invalidation application are different in time and unit, but they are all a means to protect trademarks provided by the Trademark Office to the majority of trademark owners. However, in practical cases, many enterprises take trademark objection and trademark invalidation as weapons to actively achieve their brand strategic goals. 1. Trademark objection is aimed at "trademarks that have been preliminarily approved and announced", that is, only trademarks are still in the stage of "preliminary approval and announcement". According to the provisions of the Trademark Law, only the trademark that has no objection after the expiration of the announcement will be approved for registration and issued with a trademark registration certificate, that is to say, the trademark at this time has not been approved for registration and is not a real trademark. 2. A registered trademark that is declared invalid shall be announced by the Trademark Office, and the exclusive right to use a registered trademark shall be regarded as the beginning. The decision or ruling declaring a registered trademark invalid has no retrospective effect on the judgment or ruling of trademark infringement cases made and executed by the people's court before the invalidation, the conciliation statement, the decision on handling trademark infringement cases made and executed by the administrative department for industry and commerce, and the trademark transfer or use license contract that has been performed.
