You may want to register your design outside of Belize, to obtain protection in other countries. The Hague System for the International Registration of Industrial Designs provides a centralized registration system where you can e-file up to 100 designs and target over 92 territories in one single application that you could use to claim priority on in further filings.
Any individual or business in Belize can file an international application under the Hague System. For more information on filing an international application, geographical coverage and fees, and to get started, please go to www.wipo.int/hague/en.
