A good patent application should include in the patent application documents the main technical scheme that can realize the patent technical effect, including two or more forms of a component, as the content of patent protection, so as to prevent others from being inspired by your patent, adopt other possible technical schemes to realize the technical effect of your patent disclosure, and even further apply for a new patent, which will bring you trouble or economic losses. At the same time, it should be noted that in the claims, the characteristics of each technical solution (including various forms of a component) should be expressed. Expand the scope of patent protection as much as possible.
