If there is novelty, the novelty of the invention patent shall be enjoyed within 12 months from the date of first publication. Article 22 of my country’s Patent Law stipulates: “Inventions and utility models for which patent rights are granted shall possess novelty, creativity and practicality. Novelty means that no identical invention or utility model has been published at home or abroad before the filing date. The same invention or utility model has been published publicly, used publicly in China, or otherwise known to the public, and no other person has applied for the same invention or utility model to the Patent Administration Department of the State Council and recorded it in the patent application documents published after the application date. ."
