1. Can a trademark be still used after it has been cancelled? If a trademark is cancelled, it cannot be used. It is unreasonable for a trademark to be canceled and registered by someone else. Article 50 of the "Trademark Law of the People's Republic of China" clearly states that if a registered trademark is revoked, declared invalid, or expires and will not be renewed, within one year from the date of cancellation, declaration of invalidity, or cancellation, The Trademark Office will not approve trademark registration applications that are identical or similar to the trademark. 2. What is the definition of trademark squatting? The meaning of trademark squatting has gone through two stages of development. In the first stage, the objects of trademark squatting are basically limited to unregistered trademarks; at this stage, the connotation of trademark squatting has been further expanded, and other people’s trademarks or well-known trademarks that are already well-known to the public apply for registration on non-similar goods or services. This behavior also belongs to squatting. Furthermore, the act of applying for registration of other people’s innovative designs, design patents, company names and trade names, copyrights and other prior rights as trademarks should also be regarded as trademark squatting. Trademark squatting can be divided into a narrow sense and a broad sense. Trademark squatting in the narrow sense refers to the competitive behavior of registering a trademark before the original trademark owner to obtain economic benefits. 3. Three tips to prevent trademark squatting 1. Before the market moves, trademarks go first. Before newly developed products enter the market, ensure that the rights to the trademarks used have been obtained. 2. Defensive registration: According to the principle of “one application for one trademark for one category of goods”, trademarks with a certain degree of popularity can be defensively registered separately for similar or non-similar product categories to the trademark to protect them from professional trademark speculators. 3. Strengthen trademark monitoring: Enterprises should pay close attention to the "Trademark Announcement" promulgated by the State Administration for Industry and Commerce. If identical or similar trademarks are found, they should promptly raise objections to the State Administration for Industry and Commerce; they should entrust a trademark agency to organize market tracking and monitoring, and provide timely feedback on infringement information. 4. Other matters needing attention in trademark registration There are currently two major trademark authorization principles in the world. One is the first-to-use principle represented by the British and American legal systems; the second is the first-to-application principle represented by the Chinese civil law system. After understanding some basic knowledge of the laws of the country of squatting, we can then analyze the specific issues in detail (taking different countermeasures for different situations). In addition, these companies should submit their own trademark registration applications after successfully preventing the registration of squatting trademarks. Relevant enterprises should collect evidence of the use of their trademarks in the country of registration as early as possible, as well as relevant evidence that their trademarks are well-known, and relevant evidence that can prove the other party's malicious preemptive registration, and prepare for judicial relief. To sum up, if a trademark is canceled, it can no longer be used, and within the one-year protection period after cancellation, others are not allowed to register the canceled trademark. Although it has been canceled procedurally, others are not allowed to register it. If you violate the registration of the trademark, the original trademark owner can still sue others for using the trademark.
