Legal analysis: 1. If the contractor of a contract infringes the patent rights of others because he accepts the entrustment of the client, and the contractor knows or should know that the client does not have a corresponding patent license, The infringement should be stopped and the infringement should be jointly and severally liable with the ordering party. 2. Because the actual manufacturer is a participant in product manufacturing, he should also bear tort liability according to law. 3. Be cautious about whether the client and processor of "processing with supplied materials" bear joint and several liability in patent infringement.
