second, what are the similarities between defensive trade mark and the joint trademark? defensive trade mark and the joint trademark have the same purpose of registration: to protect well-known trademarks from infringement and prevent others from innuendo. 1, the emergence of joint trademarks, because the similarity of trademarks or goods is often not clear, there is no strict judgment criteria, and it changes with the time and place, so it is difficult to prevent others from registering or using similar trademarks on similar goods, and once this happens, it is often difficult to cancel the registration of others or prohibit the use of others. Therefore, people register joint trademarks to prevent this from happening, which plays a preventive role. Some also forced manufacturers to register joint trademarks because of the infringement of similar trademarks. 2. The purpose of registering a joint trademark is also to meet the needs of enterprise development and new product development. For powerful enterprises, there are many kinds of products, new products are constantly emerging, and old products are constantly updated. Therefore, in business dealings, it is necessary to use a trademark similar to the original registered trademark on new products similar to Hu's goods, which can not only promote sales with old brands, but also show the elegance of new products, which can be described as killing two birds with one stone. The joint trademark can just meet this need. China's trademark law does not stipulate the contents of joint trademarks, but many manufacturers have actually applied the joint strategy to give full play to the role of joint trademarks.
third, the role of joint trademarks. Q&A: What role can joint trademarks play? What is the specific role? The lawyer replied: The joint trademark has the following functions: 1. The subject of the joint trademark is also the owner of original trademark, and the two should be consistent. The goods approved for use by the joint trademark are the same as or similar to those approved for use by original trademark. Moreover, the joint trademark should be similar to original trademark in sound, form and meaning. 2, joint trademark registration is not for use, but to form a protective fence of the main trademark. 3. Joint trademarks can be registered separately, but each trademark can not be transferred separately, but the whole joint trademark must be transferred together, as well as the joint trademark license. 4. Each trademark in the joint trademark is relatively independent, and the revocation or termination of one trademark does not affect the effectiveness of other trademarks. The above is the relevant legal knowledge about the difference between defensive trade mark and joint trademarks. To sum up, we can learn that joint trademarks are suitable for enterprises that only operate one kind of products, while defensive trade mark is suitable for enterprises that operate multiple kinds of products. Joint trademarks are similar product trademarks registered in the same kind of trademarks to ensure the exclusivity of your products in such trademarks.
