How do courts protect patent rights?

As an intangible property, patent right can be the object of property preservation in people's courts. When the people's court carries out property preservation of the patent right, it shall serve a notice of assistance in execution to China National Intellectual Property Administration, stating the matters needing assistance in execution and the time limit for property preservation of the patent right, and attach the ruling of the people's court. Two, the pledged patent right can also take property preservation measures, but the pledgee has the priority to be compensated. As for the exclusive license contract signed between the patentee and the licensee, it does not affect the patentee's right status, and property preservation can also be adopted.
