What materials should be prepared for the process and steps of patent application?

First, prepare the patent documents, including: 1. To request, press 2. Claim, 3. Description summary, 4. Summary chart, 5. Description (including drawings). Then send the documents to the patent office by registered mail (not express or ordinary mail). If you haven't applied for a patent, you'd better ask for help from a patent agency or someone who has applied for a patent. All documents have a certain format, and punctuation is not enough. The success rate of self-management is very low, and it will get out of hand. At that time, it was useless to find anyone. The patent office only wants documents, not objects or photos. You will receive a letter from the Patent Office about half a month after the document is sent. If the patent is accepted, you should send the application fee to the patent office. We'll wait later. The utility model patent takes eight to nine months, and the invention patent takes about two and a half years. The patent office authorizes the notice to remit money to the patent office as required, and the patent office will issue you a certificate. After paying the annual fee every year, there is nothing else. In the meantime, if the patent office doesn't write it, it is best that the patent can be authorized. If the patent office writes it, it will generally be over, and the application will be rejected, with a sieve. It's hard to get recognition. A patent must have three characteristics: novelty, practicality and creativity before it can be approved.
