First of all, you already know that the protection of invention patents lasts longer. Secondly, the application process of invention patent is more strict because it has to go through substantive examination, which requires the invention itself to be fully novel, creative and practical. The utility model patent is relatively simple, just a general small invention and small creation, and there is no strict requirement like the invention patent in the application process. Therefore, if there is patent infringement, it is more likely that the utility model patent will be invalidated and declared successful. Invention patents are not easy to be invalidated and declared successful because of substantive examination. For large enterprises, because the patent application has a certain application time, it is better to judge whether this patent can be used as the core patent for the subsequent operation of the enterprise through the invention patent.
Second, it takes a long time to accept the examination and approval of invention patents, and it takes longer to get the license. The utility model patent can get the certificate faster, so you need to apply for the utility model patent at the same time, even if your patented technology content has reached the requirements of the invention patent, if you want to play a protective role in advance, let your product open the market in advance.
Thirdly, in the case of our Shenzhen company, invention patents can get more government project funding, which can also be more helpful for the company to evaluate municipal high-tech enterprises and national high-tech enterprises. Therefore, products that can apply for invention patents should apply for invention patents as much as possible, which is helpful for future enterprise projects.
