What kind of inventions can be patented and patented?

Generally speaking, new products that can be mass-produced, as well as their manufacturing methods and usage methods, can be patented, but in order to obtain a patent, three substantive conditions must be met: novelty, creativity and practicality. Inventions and utility models granted patent rights should be novel, creative and practical. Novelty refers to the fact that the same invention or utility model has not been published in domestic and foreign publications before the filing date, has been publicly used in China or is known to the public in other ways, and has not been applied to the Patent Office by others and recorded in the application documents published after the filing date. However, under any of the following three circumstances, there may be a grace period of six months: (1) it will be exhibited for the first time at an international exhibition sponsored or recognized by the China Municipal Government; (2) It was first published at an academic conference or technical conference convened by the relevant competent department of the State Council or a national academic group; (three) without the consent of the applicant, others disclose its contents. If an application for a patent is filed within six months from the date of occurrence of these three situations, novelty will not be lost. 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. The design that has been granted a patent right shall be different from or not similar to the design that has been published in domestic and foreign publications or used publicly in China before the date of application. In short, it should be novel and original.
