Legal analysis: unregistered trademarks can generally be used. However, registration is required by law. And the general trademark is used in the market without registration, which is not protected by law. According to the relevant laws and regulations, if a unit or individual needs to obtain the exclusive right to use a trademark for its goods or services, it shall apply to the Trademark Office for trademark registration. Goods that are required by law to use registered trademarks must apply for trademark registration, and those that have not been approved for registration may not be sold in the market. Trademark registration needs to follow the principle of combining voluntary registration with compulsory registration. Most trademarks in China adopt the principle of voluntary registration. Business operators of commodities (mainly cigarettes, cigars and packaged cut tobacco) that must use registered trademarks according to the laws and administrative regulations of the state must apply for trademark registration. Without the approval of registration, the commodities shall not be sold in the market. The use of unregistered trademarks is not protected by law, and if others rush to register, it may cause infringement. There are still the following risks in using unregistered trademarks: 1. Trademarks are not protected by law and cannot effectively participate in competition by modern propaganda means. 2. The trademark used by an enterprise is not registered, and the fatal weakness is that the trademark user does not enjoy the exclusive right to use the trademark. 3. Once others register the trademark first, the first user of the trademark can no longer use the trademark. 4. Unregistered trademarks cannot form intellectual property rights protected by law, so the unregistered trademarks are intangible assets. 5. Can't declare famous trademarks or famous brands and other related enterprise honors. 6. The bigger and stronger an unregistered enterprise is, the more vulnerable it is to malicious imitation or cybersquatting by other enterprises, bringing losses to itself. 7. Local industrial and commercial bureaus at all levels supervise the quality of goods and services through the management of trademarks.
