How to apply for a patent for an individual invention (postdoctoral fellow in Tsinghua)? What kind of services can the patent office provide? Can I write my own application documents? please

The landlord's question is really professional. As far as I know, Venice promulgated the first patent law in the world in 1474, so Venice was the first country to implement the "patent system". At that time, the patent application documents were written by the inventor himself, and the patent examination right was held by the court judge, without a special patent agent. However, with the continuous development of patent systems in various countries in the world, the classification of patent applications is becoming more and more detailed, and the strictness of examination terms is also increasing. It is difficult to successfully pass the examination of the state official institutions only by relying on the inventor's own patent application documents. Therefore, some inventors, judges, lawyers and other related people specialize in the process and exercise skills of patent application. Imagine that the patent system has been in existence for 537 years. As an inventor, it is difficult for an individual to master the writing rules and precautions of patent application documents in a short time. So my personal suggestion is to find an intellectual property agency and subcontract the patent application to the agent, so that you will save a lot of precious time to continue research and development and invention. At present, there are about 793 intellectual property law firms in China, and some law firms can also provide the service of writing patent application documents. You can choose one to help you apply for a patent. Good luck!
