What are the necessary conditions for granting the invention patent right in China?

Article 22 of the Patent Law stipulates that inventions and utility models granted patent rights shall be novel, creative and practical. Novelty means that before the filing date, no identical invention or utility model was published in publications at home and abroad, used in China or known to the public in other ways, and no identical invention or utility model was applied to the patent administration department in the State Council by others and recorded in the patent application documents published after the filing date. Creativity means that compared with the prior art before the filing date, the invention has outstanding substantive features and remarkable progress, and the utility model has substantive features and progress. Practicality means that the invention or utility model can be manufactured or used and can produce positive effects. Therefore, novelty, creativity and practicality are the necessary conditions for granting patents for inventions and utility models. At the same time, Article 23 of the Patent Law stipulates that a design granted a patent right shall be different from or similar to a design that has been published in publications at home and abroad or used in China before the date of application, and shall not conflict with the legal rights previously obtained by others. This is a substantial condition for granting the patent right of design.
