Rulings on PIs enter into force immediately. Court action A patent holder may file a claim demanding the termination of intellectual property rights infringement, withdraw from the turnover objects infringing intellectual property rights, recover damages/lost profits, etc. Jurisdiction of the dispute depends on the par- ties: if individuals are involved as parties to the dispute, the civil courts shall consider the case; and if only legal entities are involved, the com- mercial courts will be appropriate.
