In light of changes to U.S. sanctions and export policy in Cuba, businesses should now consider brand protection in that country.
Being first to file in Cuba will help to deter third parties from infringing your brand. And starting the process now will give you an advantage. The Cuban trademark clearance and application process is slow, and is expected to get even slower as the system is flooded with new applications.
Assuming your trademark is clear in Cuba, the costs to register it are relatively low. The benefits of a protecting your brand with a Cuban trademark registration are large: your company will be positioned to conduct businesses in this new market, and will be able to fend of trademark counterfeiters.
I have an established relationship with local counsel in Cuba, and would be happy to facilitate the clearance and registration of your mark in that country.
