I want to ask my family, there is an ancestral prescription called plaster, which has many functions of autocracy, trauma and detoxification. How much does it cost to apply for a patent?

Patent protection is not a good choice if you don't have enough funds to develop this drug.

It takes two to three years to apply for such a patent of traditional Chinese medicine, and the corresponding fees have to be paid before and after authorization, ranging from thousands to tens of thousands. And the annual patent maintenance fee needs 900-8000 yuan.

At present, the domestic technology market is not perfect. At the initial stage of your patent application and authorization, it is difficult to transfer it successfully, and it is often deceived by companies or individuals with ulterior motives in the society under the banner of investment, resulting in property losses.

For example, patents are like your own children. It's best to raise it yourself after birth, not for others. If you can't raise it yourself, you'd better not.
