Is it necessary to apply for an invention patent after the invention comes out?

according to China's patent law, detailed rules for implementation and other relevant laws and regulations, the applicant only needs to provide a paper description of the drawings when applying for an invention patent, and does not need to provide the physical object. In view of the fact that you only have ideas, you should be reminded of the three requirements of patent application: according to Article 22 of the Patent Law, inventions and utility models granted patent rights should be novel, creative and practical.

Novelty means that no identical invention or utility model has been published in domestic and foreign publications, used in China or known to the public in other ways before the filing date, and no identical invention or utility model has been filed with the patent administration department of the State Council by others and recorded in the patent application documents published after the filing date.

creativity means that compared with the existing technology 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.

it is a seemingly simple and extremely complicated process to turn an idea into a realizable product or technology and get full protection through patent application, because a good patent technology needs a fairly high level of patent application document writers to get the most full protection. If your idea is really good, I suggest you carefully choose a senior patent agent to help you write the application documents. It would be a pity to prevent a good technology from being ruined.
