Hello, I seem to have encountered your problem before. Here are my original ideas and methods to solve it. I hope I can help you. If there are any mistakes, I hope you will forgive me! First of all, app belongs to a software program, and should apply for registration in the commodity item of "Computer Software (Recorded)" in Category 9, Group 1 of the Similar Goods and Services Classification Table. Although this product item is called "Computer Software (Recorded)", it doesn't completely correspond to "Mobile Phone Software", because the Table of Similar Goods and Services doesn't keep up with the development of science and technology. I think the product item of "Mobile Phone Software" will appear in the first group of Category 9 of the Table of Similar Goods and Services in the next revision. Does the mobile app need to apply for software copyright and trademark? 1. Copyright comes into being when the work is completed. If there is a clear evidence preservation system and it is necessary to apply for any project subsidy or enter some markets for external reasons, the significance of applying for copyright registration is actually not too great. Of course, after applying for software copyright registration, the advantage is that it is easy to confirm the copyright of your work. When there is external demand, such as applying for subsidies, you don't have to cram temporarily. At present, Guangzhou and other cities subsidize software copyright, and the cost is not high. It is suggested that if someone has it, they should apply for registration in case of a city from time to time. 2. Trademark is a sign that consumers distinguish the source of goods or services. The difficulty of applying for a trademark by app lies in the lack of a clear definition of goods in the application process. At present, our suggestions are all relatively extensive protection. The resulting investment will also increase. For this reason, trademark protection is necessary if you are worried that your app name or other distinctive signs will be fraudulently used by others and your popularity will be used to seek illegitimate interests. The advantages of applying for software copyright and trademark in mobile app 1. It is easy to confirm the copyright of the work; 2. Get convenience when applying for subsidies; 3. At present, the price of applying for subsidies for software copyright is relatively cost-effective, so apply for registration in case of emergency; 4. Trademark is an important symbol for consumers to distinguish the source of goods or services; 5. The difficulty of software trademark application is the lack of a clear definition of goods in the application process, which will increase the investment. Based on these factors, trademark protection is necessary if you are worried that your software name or other distinctive signs will be used by others and your popularity will be used to seek illegitimate interests. To sum up, the advantage of applying for a trademark is that once someone infringes on rights and interests, we can directly produce strong evidence to make the infringer bear legal responsibility. Moreover, having your own trademark and copyright will also have a certain influence in brand building. Thank you very much for your patience.
