Only trademarks approved by Changchun Trademark Office can be called registered trademarks. If people are not careful when using trademarks, their hard registered trademarks will be invalid or rejected without approval. Therefore, enterprises need to know some knowledge to prevent enterprises from being invalidated unconsciously.
The first is the principle of trademark priority. Trademark registration in China has always followed the "prior principle", that is, if someone submits the same or similar trademark one day earlier than you, your trademark will be rejected. Therefore, the applicant must submit the application as soon as possible, so as to get the trademark registration certificate and put it into the market as soon as possible, and avoid using it without a trademark registration certificate.
Suppose you come across a trademark applied for on the same day. In this case, when applying for a trademark, the Trademark Office will send a supplementary notice on the use of evidence to all applicants who apply on the same day. If everyone provides evidence of use, or fails to provide evidence of use, then the applicant can mediate by himself. If the negotiation fails within the specified time, the Trademark Office will draw lots to decide the applicant.
Regarding the naming of trademarks, we must abide by the provisions of the Trademark Law, and we must not contain signs prohibited by the Trademark Law, such as country names, national anthems and national emblems. And the trademark name shall not have a negative impact on society. At the same time, the trademark shall be distinctive and shall not be the same as or similar to others' trademarks. After choosing a good name, you should make a trademark inquiry, and then adjust and optimize it.
If similar trademarks are registered in the same category, you can see whether similar trademarks are used normally. If you don't use it, you can apply to the Trademark Office for cancellation. If the other party cannot provide valid evidence for the use of the trademark, the trademark will be revoked.
The final rejection review is still necessary. When the trademark is rejected, there may be subjective factors of the examiner, so it may be easy to pass the review. Therefore, it is necessary to actively review and win opportunities for trademark registration.
