1. Registration protection: The most effective way to protect a trademark is through registration. According to my country's Trademark Law, only registered trademarks can be protected by the Trademark Law and relevant regulations, while unregistered trademarks cannot be protected by the Trademark Law. Therefore, brand names, especially those that have become famous brands, Converting the name into a legally significant trademark name and logo is undoubtedly a shortcut to effectively protect the brand name. 2. Objection protection: Use trademark opposition, the basic procedure of trademark substantive examination, to protect trademarks with prior rights and interests. This mainly uses programs to achieve the purpose of protection, which is relatively simple. At present, the Trademark Law stipulates that objections to trademarks announced in the preliminary examination can be filed with the Trademark Office. If you are not satisfied with the ruling, you can also file a review with the Review and Adjudication Committee. If you are still dissatisfied, you can continue to file an administrative lawsuit with the People's Court. 3. Review protection: Registered trademarks that pose a threat to previously registered trademarks and are considered controversial or improperly registered, or trademarks that have been registered by improper means, can be revoked by applying to the Trademark Review and Adjudication Board to achieve the purpose of protection. This is a remedy after missing the opportunity to object. According to the procedure, it takes 2 to 4 years or even longer. Moreover, the problem is that before the review makes a decision, the reviewed trademark is still considered to be a valid registered trademark and is protected. 4. Well-known trademark protection: Special all-round cross-class protection can be achieved by identifying well-known trademarks. There are two solutions: active recognition by applying to the National Trademark Office for recognition or passive recognition by requesting judicial recognition through a certain infringement case. As a strict legal concept, well-known trademarks are recognized in individual cases such as objections, reviews, infringements or lawsuits. It refers to a trademark that is widely known to the relevant public in China and has a high reputation. From the current point of view, my country's protection of well-known trademarks has changed from the previous practice of batch recognition and centralized management to the international practice of case-by-case recognition and passive protection. Trademarks must be registered with the Trademark Office, otherwise they will be invalid. If you use a trademark without a registered trademark, you don’t know whether the trademark you are using is one that has been registered by others. If you are using a trademark that has been registered by others, it is very likely to be counterfeited by others. In this way, you can maintain your own trademark publicity and a series of investments. All the expenses were wasted.
