Patent System & Process

Patent System in Bangladesh

Bangladeshi invention patents are administered by DPDT under the Patents and Designs Act, using a first-to-file system. Bangladesh joined the PCT in 1985, with national phase entry typically at 31 months from the priority date. **Important: Bangladesh is currently NOT a Madrid Protocol member. Trademark protection in Bangladesh requires a direct national application.** As a Least Developed Country (LDC), Bangladesh benefits from certain TRIPS flexibilities.

No Madrid Protocol — Direct Trademark Filing Required ▾

Bangladesh has not yet acceded to the Madrid Protocol (as of 2026), so it cannot be designated in WIPO Madrid international trademark applications. Trademark protection in Bangladesh requires a direct national application with DPDT. Monitor developments on Bangladesh's potential accession to the Madrid System.

LDC TRIPS Flexibilities ▾
