Writing patent application documents is for professionals of patent agents. If you have long-term experience in this field, of course you can write it out. You can refer to the patent literature retrieved by China National Intellectual Property Administration in the early stage of writing. Patent application documents include: specification, claims, abstract of specification, drawings of specification (the invention may be based on the situation, but the utility model must have drawings), abstract drawings, etc. There is also a patent application request. The description includes: name, technical field, background technology, invention content, attached drawings and specific implementation methods.
You just joined the work and have no practical experience in this field. It is difficult to write such a document. Maybe your boss doesn't understand this situation. If a patent is not well written, especially the patent claim is not well written, then the patent is completely useless and cannot be protected.
As for how to do it and how to write it, please ask a patent agency to do it, because there are still some other documents to submit a patent application, and you still have to ask an agency to do it.
But you can learn a lot about this by contacting the agency. I think I can write it myself if I do too much in the future.
