For example:
Our company has a patent in China.
The patent of the same product has been noticed by other foreign companies (such as the United States).
Can I still sell things to America?
If I sell it to America, will he charge me?
He sold it to China. Do you want to give me money?
A: If the foreign patent right doesn't belong to you, then selling the same kind of goods to that country is infringement. As the patent law is regional, your patent right can only be exercised in China. If the other party comes to China to sell similar products, it is also infringement in theory, unless they can find enough evidence to declare your rights invalid. Therefore, at present, he or you need to pay patent fees to the other country to sell products.
