Trademark Registration in Bangladesh: Complete DPDT Filing & Protection Guide

Registering a trademark with the Department of Patents, Designs and Trademarks (DPDT) under the Trademarks Act 2009 grants the brand owner exclusive legal rights to use, license, and protect their brand name, logo, or slogan against commercial counterfeiting and trademark infringement.

Validity: Once registered, a trademark certificate is valid for 7 years from the application filing date and is renewable perpetually in 10-year increments.

Step 1: Pre-Filing Trademark Search

Before submitting an application, conduct a comprehensive trademark search across the relevant Nice Classification classes (Classes 1–45) to ensure no conflicting or identical marks are already registered or pending examination.

Step 2: Filing Application (Form TM-1)

• Submit Form TM-1 along with clear representations of the mark, applicant particulars, and specification of goods/services.

• Receive an official application number establishing your priority filing date.

Step 3: Examination and Journal Publication

• The DPDT examiner reviews the application for distinctiveness and absence of conflict with existing marks.

• Upon acceptance, the trademark is published in the official Trade Marks Journal.

• A statutory 120-day opposition window allows third parties to contest the registration.

Step 4: Registration Certificate Issuance

If no opposition is filed (or if opposition proceedings conclude in the applicant's favor), the Registrar issues the official Certificate of Registration (Form TM-11).
