What's the difference between trademark objection and invalidity? 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. 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 executed trademark transfer or use license contract. Trademark Objection Trademark objection refers to that the prior obligee or interested party thinks that the trademark preliminarily approved by the Trademark Office to be announced is illegal, and puts forward an opinion not to register to the Trademark Office within 3 months from the date of announcement. Trademark objection defense trademark objection defense refers to the trademark that the trademark applicant enters the trademark announcement period after the trademark application has passed the preliminary examination. According to the provisions of the Trademark Law, other rights holders or natural persons raise objections to the trademark, and in order to ensure the successful application for registration of the trademark, they put forward defense reasons for their objections. After accepting the application for trademark objection, the Trademark Office will send the dissenter's Application for Trademark Objection and a copy of the objection reasons and evidence materials to the dissenter or the dissenter's agency. The Trademark Law stipulates that the respondent must submit the defense materials to the Trademark Office within 30 days from the date of receiving the trademark objection. If the objector fails to give a written reply within a limited time limit, it shall be deemed as giving up the right of reply. Moreover, the Trademark Office will make a ruling according to law regardless of whether the dissenter fails to reply or not within the prescribed time limit. Trademark objection, there may be some problems in the process of trademark registration, which makes the objection exist. As long as the objection is eliminated after the expiration of the announcement, it can be registered according to law. However, if the trademark is invalid, then the registration cannot be completed at all, and the registration is invalid from the beginning.
