You do not say what your doubt is regarding patents so i cannot answer. Also, there is no such thing as an international patent. It is an international patent application that is a gateway to obtaining a patent in any of over 100 countries. You obtain a search and an informational assessment of patentability which you can then use for deciding whether or not you wish to proceed with a patent application in any of the member countries based on the content of the international patent application.
