Patent litigation is closely related to the operation of patent pool. The operation of patent pool is based on the realization of commercial value, paying more attention to the control of the market, hoping to realize the monopoly of technology through favorable solidification. Its operation mode includes patent licensing, patent transfer, patent cross-licensing, patent strategic alliance, patent litigation, patent pledge loan, patent securitization, patent incubation, enterprise merger and acquisition, etc. Among them, patent litigation is one of the ways to solve the problems in patent operation. Patent portfolio, patent pool or patent leasing enterprises can safeguard their own interests and realize patent value when they reasonably claim patent rights by suing infringers.
