My own invention patent was rejected. I want to ask an agent to help me write a review. How much will it cost?

First, look for freshness. If the same patent and similar technical content are not disclosed in advance, you can consider applying. 2. Write the application documents, including the specification, the claims, the abstract of the specification, the appended drawings of the specification and the appended drawings of the abstract. Third, the application can be submitted by registered mail to the State Patent Office in Beijing, or in person to the State Patent Office or the agency of the State Patent Office. Fourth, pay the application fee. If it is an invention patent, you need to pay the substantive examination fee. Step 5, review the procedure and reply to the notice of review opinions. Step 6, authorize or refuse. 2. How much is the application (the whole process): If you apply by yourself, the application fee for invention patent is 950 yuan, the examination fee is 2,500 yuan, the certificate fee after authorization is 255 yuan, and the annual fee is 900-8,000 yuan/year. After the utility model or authorization, the certificate fee is 225 yuan and the annual fee is 600-2000 yuan/year. The application fee and examination fee can be reduced, and the minimum invention can be reduced to 560 yuan (application+examination), and the minimum utility model or design can be reduced to 75 yuan. If you entrust an agent, you have to pay a patent agency fee, ranging from several hundred to tens of thousands. 3. How long does it take: from application to authorization, if an agency is entrusted, the invention needs about 3 years of authorization. The authorization period of utility model or design is about 65,438+0 years. If you don't entrust an agency, the authorization time of invention patents will often exceed 3 years, but there are also less than 3 years. Depending on the specific situation, it is for reference only.
