Technical solutions that are only recorded in the patent description and drawings but not reflected in the patent claims cannot be included in the scope of patent protection. That is to say, the scope of protection of patent rights cannot be determined based on the description and drawings. If a technical solution is fully disclosed in the patent specification and has specific descriptions and embodiments, but is not recorded in its claims, it should be deemed that the technical solution is not within the scope of patent protection, and no interpretation of the patent is allowed. When filing a claim, it shall be included in the scope of patent protection. If the technical content recorded in the patent claim is different from the description or embodiment in the patent specification, the description in the patent claim shall take precedence, and the content recorded in the specification and drawings cannot be used to "correct" the content recorded in the patent claim. content. If the scope of the technical content disclosed in the patent description and drawings is wide, but the scope of protection requested in the patent claims is narrow, in principle, the scope of protection of the patent right can only be determined based on the technical content in the claims.
