What should I do if I find an agency for invention patents?

You must be an undergraduate. 1. If you feel that your patent is of little practical value and just stick some gold on it, you can apply for a written document at the science and technology department of the school, or you can't write it. The staff of the science and technology department will usually teach you and they will help you with the agency work. The disadvantage of this is that the applicant must be a "school", that is, the patent belongs to the school and you are only the inventor, but the advantage is that you don't have to pay all the fees. If you can get a patent authorization in the future, the school may still have some rewards, but the chance is slim, because an invention patent will take at least two or three years. 2. If you think that your patent has certain practical value and can be effectively put into actual production and bring profits in the future, you can consult your local patent office and ask them for the best local agency. This depends on your personal economic strength, and the agency fee for invention patents is at least four or five thousand, which is not worth it. In addition, patents applied by individuals are generally of little use now. 3, you can try to write it yourself, in fact, it is very simple to write, the key is to write the instructions and claims well. In this case, if you can apply, it will cost several hundred dollars. Finally, I would like to remind you that if you want to search clearly on China Patent-Information Retrieval Online, it depends on whether you have done anything before. If you have it, even if it is similar, your application for a patent for invention will be rejected when it comes to the actual trial. Good luck!
