According to my country's "Patent Law" and implementation rules and other relevant legal provisions, applicants only need to provide paper descriptions of drawings when applying for invention patents, and do not need to provide physical objects. For the situation where you only have ideas, I would like to remind you that you should pay attention to the three requirements for patent applications: According to Article 22 of the Patent Law, inventions and utility models for which patent rights are granted must have novelty, creativity and practicality.
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.
If you want to turn an idea into an achievable product or technology and obtain full protection through patent application, it is a seemingly simple but extremely complicated process, because a good patented technology is the most fully protected. Protection requires writers of patent application documents to have a very high level. If your idea is really good, it is recommended that you carefully choose a senior patent attorney to help you write application documents. It would be a shame to prevent a good technology from being wasted.
