What is the difference between indirect patent infringement and joint patent infringement?

Indirect infringement means that the behavior of the actor does not constitute direct infringement of others' patents, but abets, helps and induces others to implement patents, resulting in direct infringement. Subjectively, the actor intentionally induced or instigated others to infringe the patent right, which objectively provided the necessary conditions for the occurrence of direct infringement.

* * * Tort refers to an act in which two or more actors have the same intention or negligence, or their torts are directly combined to produce the same damage consequences, resulting in personal or property damage to others. * * * The same injury constitutes the same tort. Article 130 of the General Principles of Civil Law stipulates that if two or more people infringe upon and cause damage to others, they shall be jointly and severally liable.
