Legal analysis: it works. A patent certificate is a document issued by the patent office to prove the patent right. After the patent application is examined and approved, the Patent Office shall make a decision to grant the patent right and issue a patent certificate. The patent certificate mainly records the name and patent number of the invention-creation, the names of the inventor and designer, the name and title of the patentee, the scope of rights protection and the time when the patent was granted. From the date when the patent recorded in the patent certificate is granted, others may not use the patent without permission. Patent right is the exclusive right of the patentee to use his invention and creation, and patent infringement refers to the illegal act of implementing a valid patent protected by law for the purpose of production and operation without the permission of the patentee. Pass off non-patented products as patented products and pass off non-patented methods as patented methods. According to the provisions of Article 65 of the Patent Law, such acts need to bear general civil tort liability, and the administrative department for patent affairs shall order them to make corrections and punish them fairly.
Legal basis: Article 39 of the Patent Law of People's Republic of China (PRC). If the application for a patent for invention is not found to be rejected after substantive examination, the administrative department for patent in the State Council shall make a decision to grant the patent right for invention, issue a patent certificate for invention, and register and announce it at the same time. The invention patent right shall take effect as of the date of announcement.
