Trademark search and registration are necessary tasks before product development and launch. However, many Internet companies, especially some start-up companies, are blank in this aspect. Your situation is not an isolated case. A suggestion to your boss: Find a reliable intellectual property agency. Before product development, technology, marketing, planning and agency companies must hold meetings to determine the technical protection plan and brand protection plan while avoiding possible infringement risks. China Unicom registered the "Chaoxin" trademark as early as 2006. As long as you have consulted about trademark matters, it will not be like this. Recently, I have handled several cases involving APP names, and I have a deep understanding of this. If you like the name, you should register a trademark as soon as possible. Someone else has already registered? Then you should change your name as soon as possible, which is the lowest cost. If you really like it, you should buy the trademark. Of course, if it is China Unicom, it will basically not sell it, because they are not short of money. Next, if China Unicom does not complain, you can continue to use it. If you file a complaint, I'm afraid you will have to change your name. The only gap is the prior use defense in trademark law. Therefore, conducting trademark searches as early as possible can help reduce, avoid and recover losses in discovering trademark squatting. If you find out through inquiry that the preemptively registered trademark is still in the application stage and has not yet been registered, you can promptly file an objection during the opposition announcement period. Method one is to revoke China Unicom's "Chaoxin" trademark. This method is theoretically feasible but has very little operability; Method two is to buy China Unicom's "Chaoxin" trademark because it is willing to sell it and you can afford the price, but it has very little operability; Method 3: Change the name. If the two characters are basically saturated, change the name, or consider adding a word, such as "Chaoxin Ruida"; PS: If you don't change the name, you may earn much less now than you may receive in infringement compensation in the future. Copyright and The content of trademark protection is different.
