Is He Zhiyang's patent true?

No. The abbreviation of patent right refers to the patent right enjoyed by the patentee for his invention and creation, that is, the state grants the inventor or his successor the exclusive right to use his invention and creation within a certain period of time according to law. He Zhiyang didn't find it from open channels, so it's not true. A patent certificate issued by the Patent Office confirming the applicant's patent right for his invention or creation or a patent document recording the contents of his invention and creation refers to a specific material document.
