Bangladesh IP Filing Guide

Bangladesh is administered by the Department of Patents, Designs and Trademarks (DPDT). Bangladesh is not a PCT contracting state, so patent protection requires direct national filing only. The trademark system does not permit multi-class filing. Bangladesh joined the Madrid Protocol for international trademark registration.
