Whether to steal patents

You don't have to be high-tech to apply for a patent. As long as your technical scheme meets the three characteristics of patent (novelty, creativity and practicality), you can get a patent. But applying for a patent is to disclose your technical scheme, and then the state will give it some time to protect and monopolize the market. During the validity of the patent, it is an infringement for others to implement and imitate your technology. You can take up legal weapons to protect your rights and interests. As for others applying for patents after improvement, that is a technical problem of applying for patents. First, whether the patent technical scheme and claims you applied for are not considered comprehensively enough, and whether the scope of protection of the claims can be written wider so that others can't bypass your patent. Second, whether other people's improvements are also innovative, whether his technical scheme meets the three characteristics of patents (novelty, creativity and practicality), and if it is innovative and also meets the three characteristics of patents, then other people's achievements can also apply for patents. As for the relationship between your patent and his patent, it depends on the specific situation.
