Patents are divided into inventions, utility models and designs. Prescription is suitable for applying for invention patent, because utility model protects tangible objects such as equipment and products, and design protects the appearance of products. Neither is suitable, and only the invention patent can protect the technology of the formula.
At present, the agency fees of domestic patent agencies for inventions range from 3000 to 8000. Although all provinces and cities in the country can entrust, the quality of agents in most provinces and cities is not necessarily reliable. Because how the application documents are written directly determines the prospect of authorization and the strength of technical protection. And people who don't know much about patents generally can't see how the application documents are written, so it is basically determined by the professional level and attitude of the agent. The agency fees in Beijing, Shanghai and Guangzhou are relatively high, mainly because the agency services in these places are relatively high and the attitude of agents is relatively correct (of course, it is not denied that there are agents with high level and good attitude in other places).
