First, there is no so-called international patent. Patents are all regional and can only be protected in the country/region where patents are obtained. We often say that the PCT international application is only an application to the International Bureau in anticipation of the PCT treaty, that is, the patent cooperation treaty, which can simplify some application procedures. If you really want to get a patent right, you have to let your application enter the patent offices of various countries for separate examination.
Secondly, if your business can enter other countries, then you can apply in these countries. If not, I don't think it is necessary to waste money.
