Abstract:

The act of indirect/contributory infringement of patent is relative to the act of direct infringement of patent. The conception of indirect/contributory infringement of patent is, to a large extent, to meet the practical need for the protection of the patent right. In practice, to avoid liability for patent infringement, one sometimes does not exploit all, but only some, technical features defined in a claim of a patent, or several people jointly exploit all the technical features of the claim. According to the All Elements Rule in determination of patent infringement, if an accused article does not cover all the technical features or equivalent features of a patent claim, say with one of the essential technical features or an equivalent feature missing.[第一段]
