The document discusses improvements made to the Lisbon System for the international registration of appellations of origin through revisions in the Geneva Act of 2015. Key changes included expanding the scope to also cover geographical indications, introducing more flexible options for protection, adding safeguards for prior trademark rights and other rights, streamlining application and fee procedures, and notifying grants of protection to make the system more attractive for new members. The revisions were aimed at rendering the Lisbon System more useful to states and users while preserving its objectives through the new Geneva Act adopted in 2015.
