it depends on the patent laws of various countries. Take the United States as an example. Anyone can file a patent application with the US Patent and Trademark Office and get a patent right. Of course, you can apply for a US patent and sell it. However, the regulations in China are different. Foreigners applying for patents in China must entrust a patent agency in China.

1, it depends on your purpose. If you just want a certificate, some agents can help you with 23, RMB. If the technology is advanced and you want to use it to protect the market and gain income, find an agency well, this money cannot be saved;

2. When applying for a patent, there will be a publishing process. After the publication, it can be consulted on the official website, so the chances of being seen by other companies are very high. As for fancy, it depends on your technology;

3. It is not necessary to apply for a domestic application now, but it is necessary to submit a confidentiality review. I suggest you apply for a domestic one, several thousand dollars, but there are many advantages. Generally speaking, there is no restriction for foreign enterprises to purchase foreign patents. If it is a domestic patent, it needs the consent of the state, but it is not troublesome;

4. If you don't find an agent, your foreign friends can help you accept the official documents when you apply for a patent. When foreign enterprises want to cooperate, you can ask your friends to help you make a field trip. There are many swindlers these days. If you are asked to pay the money first, you must be cautious and cautious again!
