Legal basis: Article 57 of the Patent Law of People's Republic of China (PRC), where a patent is exploited without the permission of the patentee, that is, the patent right is infringed and a dispute arises, the parties concerned shall settle it through consultation. Unwilling to negotiate or failing to do so, the patentee or interested party may bring a suit in a people's court or request the administrative department for patent affairs to handle it.
