The application process is to submit your application protection scheme in the form of documents, without any physical objects.
The documents to be prepared at the application stage are: the request for a patent for utility model; Description summary; Abstract painting; Claim; Description; Attached drawings of instructions;
Where it is necessary to apply for fee waiver, relevant certificates issued by the patent administration department of the local people's government at or above the municipal level are also required.
If you have confidence in your patent and can make a profit in the future, I suggest you contact the local patent agency to help you apply. They are professionals and have a good grasp of the writing of patent application documents, so there will be no problem. The agency fee for a slightly cheaper utility model patent is 2500 yuan/piece, and a slightly more expensive one may be 5000 yuan/piece.
If you apply for the purpose of application, you can learn the relevant laws, regulations and procedures of patent application, write your own application documents, and then apply for it yourself, which can save a patent agency fee.
