First of all, you need to sort out all the ingredients, preparation methods and clinical effects of the drug. Then find a reliable agency, sign a confidentiality agreement, and then hand over the materials compiled by yourself to the agency for retrieval, and preliminarily evaluate whether you can apply (because it is likely that other documents have published this formula, in this case, it is not recommended to apply again, which will be rejected because it is not novel, and you will not get the patent right and waste the application fee).
After the preliminary evaluation determines that the application can be made, the subject needs to sign an agency contract with the agency for payment, and then the agency adjusts the scope of patent protection according to the search results and writes the application documents. During this period, it needs to communicate with the main body many times and give feedback to the manuscript. After the final application documents are finalized, the agency will submit the documents to the State Patent Office for review. Writing application documents is the foundation, which is very important, because there is nothing new to add after the patent documents are submitted, so it is necessary to consider a comprehensive and reasonable layout when writing.
The Patent Office conducts a preliminary formal examination of the application documents and a second substantive examination of the technical content. Under normal circumstances, it is no problem to entrust an agency to conduct a preliminary examination of patent applications. If an individual applies by himself, the patent may be rejected because he is not familiar with the patent law and related regulations, or the applicant may be regarded as withdrawn because he does not know how to reply, resulting in the failure of the patent application.
Substantive examination is the focus of invention patent application, and the most common problem in substantive examination is that the patent is not creative.
At this stage, the examiner will search the contents of the patented technology in the global literature (Chinese and foreign languages) to see if there is the same or similar technology as the patent. If similarities are found, a notice of review opinions will be issued, pointing out which contents have been made public and which contents are not novel or creative and cannot be authorized. At this time, the level of the agent will be tested (the inventor has no experience in patent application and can't cope with it at all). The agent will analyze whether what the examiner said is reasonable, how to reply if it is reasonable, how to reply if it is unreasonable, whether to modify the application documents, how to modify it before authorization, and strive for the maximum protection scope.
