Legal analysis: patent infringement mainly has the following manifestations: 1) The technical characteristics involved by the actor are all the same as those of the patent, which constitutes infringement; 2) The actor involves more technical features than patents, which also constitutes infringement; 3) The technical features involved by the actor are the same as the patent, but different technical features are equivalent to the patent, which still constitutes infringement; Otherwise, it does not constitute infringement.
Legal basis: Article 60 of the Patent Law of People's Republic of China (PRC), if a patent is exploited without the permission of the patentee, that is, the patent right is infringed and a dispute arises, it shall be settled by the parties 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.
