1. Utility model patents cannot protect methods. In the existing technology, salt is not added to cooking. If you add salt to cooking, this method cannot apply for a utility model patent. You can apply for an invention patent;
2. Others don’t add salt in cooking, but yours adds salt. It is novel and tastes good, which can be understood as good effect. But to what extent the effect is good, the requirement for creativity in an invention patent is “outstanding substantive features and significant In terms of "progress", "outstanding substantive features" refers to whether it is obvious and easy to think of using salt to solve the bad taste problem for those skilled in the art, and "significant progress" refers to Whether it has produced beneficial effects, that is, how good your taste is; among the three properties of the patent, novelty, creativity and practicality, the creativity is relatively difficult to pass, and it is also subject to the subjective influence of the examiner;
3. If the patent for adding salt to cooking is authorized, it is an infringement for others to add salt to cooking;
4. Judging from your addition, "If there is such a thing as salt, someone will let it go." But basically no one eats it" seems to mean "Someone has already added salt to the cooking." In this way, the patent application you apply for will not be authorized because it has no novelty. Of course, it is possible to file a patent application (as long as it meets the acceptance conditions, it will be accepted) ), but cannot be authorized.
