Yes, it is possible to file an international patent application. The World Intellectual Property Organization (WIPO) administers the Patent Cooperation Treaty (PCT), which allows for the filing of a single international patent application that covers multiple territories. The PCT membership currently includes 157 states. A PCT application, in itself, does not legally qualify as a patent, but rather maintains the priority date of the first filing. For obtaining a patent, national, territory-specific patent applications need to be filed within 30 months of the priority date of the PCT application, extendible to 31 months in many territories.
