Can American patents be converted into international patents?

If there is no corresponding patent protection in other countries, it does not constitute infringement. According to your account, it has been registered for many years. Has it been authorized for many years? It should have exceeded the priority period, so we can't apply for patents in other countries on this basis. That is to say, if this technology is currently patented only in the United States, it is basically impossible to obtain patents in other countries. As far as I know, there is no such regulation that can be "converted" into valid patents in other regions, and there is no so-called international patent (there are regional patents in Europe, but they should also take effect in various countries). Only international patent applications, patent protection in the patent laws of various countries is independent and not unified.
