1. Registered trademarks are protected by law. Article 3 of the Trademark Law stipulates that a trademark approved and registered by the Trademark Office is a registered trademark, and the trademark registrant enjoys the exclusive right to use the trademark and is protected by law. 2. The Trademark Law’s protection of unregistered trademarks embodies two characteristics: 1) There are two types of unregistered trademarks protected by the Trademark Law, including unregistered well-known trademarks and unregistered trademarks with certain influence. . 2) The rights content of the two unregistered trademarks are different. Unregistered well-known trademarks are granted the exclusive right to use, while unregistered trademarks that have a certain impact are only given priority registration rights. Article 13, Paragraph 1 of the Trademark Law stipulates: “If a trademark applied for registration for identical and similar goods is a copy, imitation or translation of a well-known trademark that has not been registered in China, and is likely to cause confusion, it shall not be registered and its use shall be prohibited.” “Trademarks” Article 31 of the Law stipulates: "Application for trademark registration shall not damage the existing prior rights of others, nor shall it be used to preemptively register a trademark that has been used by others and has certain influence by unfair means." Paragraph 2 of Article 41 It stipulates: “If a registered trademark violates the provisions of Articles 13 and 31 of this Law, within five years from the date of trademark registration, the trademark owner or interested party may request the Trademark Review and Adjudication Board to rule on canceling the registered trademark. For those who register in bad faith, the owner of a well-known trademark is not subject to the five-year time limit. "3. Ordinary unregistered trademarks are not protected by the Trademark Law. The Trademark Law does not clearly provide for the protection of ordinary unregistered trademarks. It is always in a state of no rights protection and may be prohibited from use at any time due to the approved registration of the same or similar trademark by others. Therefore, if you want to use a common trademark with security, it is best to register it. The owner of a registered trademark enjoys the exclusive right to use the trademark. When the registered trademark is counterfeited and used by others, it constitutes trademark infringement. The trademark owner can request the illegal user to bear legal responsibility. The use of an unregistered trademark by a user of an unregistered trademark is a fact, not a right.
