However, applying for a patent does not mean that you can sell drugs. As long as there is no drug approval, it is illegal for you to sell drugs.
So I suggest that you entrust a regular patent agent to apply for a patent first, and then take the information of applying for a patent to find a pharmaceutical company to cooperate and apply for a drug approval. Pay attention to the order. Do not cooperate before applying, apply before cooperating. Otherwise, under the current national conditions in China, if you tell others before applying for a patent, I'm afraid it won't be yours.
It should be noted that you must entrust a suitable patent agent to write the patent application documents, otherwise the documents will be written as garbage, for fear that no one will buy the Olympic Games.
