2- According to Article 7 of the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Laws in the Trial of Patent Infringement Disputes, the people's court shall examine all the technical features recorded in the claims when judging whether the alleged infringing technical scheme belongs to the scope of patent protection. Where the technical scheme accused of infringement protects the same or equivalent technical features as all the technical features recorded in the claim, the people's court shall determine that it belongs to the protection scope of the patent right; If the technical features of the technical scheme accused of infringement lack more than one technical feature recorded in the claim compared with all the technical features recorded in the claim, or multiple technical features are not the same or equivalent, the people's court shall determine that it does not belong to the protection scope of the patent right.
