I suggest you take a look at the Patent Law, which has clear provisions on this aspect.
Novelty means that before the filing date, the same invention or utility model has not been published in domestic or foreign publications, publicly used in the country, or otherwise known to the public, nor has the same invention or utility model been published in domestic or foreign publications before the filing date. The invention or utility model has been applied for by others to the patent administration department of the State Council and is recorded in the patent application documents published after the application date.
Creativity means that compared with the existing technology before the filing date, the invention has outstanding substantive features and significant 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.
