There are international systems for basically everything already in place now – just no overarching framework

The Hague System, also administered by WIPO, is an international registration system that allows design owners to seek protection for their designs in multiple nations through a single international application filed with WIPO. It simplifies the process of obtaining and maintaining industrial design protection internationally by enabling applicants to secure protection in any of the Hague System’s contracting parties through a single application, in one language, and with one set of fees. The Hague System has been operational since 1925 and currently has 77 contracting parties, although the United States only implemented the system in 2015.
