Patent Law and Patent Registration in Bangladesh

Bangladesh's patent system has transitioned from the historic Patents and Designs Act, 1911 to the Bangladesh Patents Act, 2023. The 2023 Act became effective in February 2025. Therefore, current patent applications and legal advice should be considered under the applicable provisions of the 2023 law and the relevant rules and procedures administered by the Department of Patents, Designs and Trademarks (DPDT).

The current framework provides procedures for filing patent applications, submitting specifications, examination, publication, opposition and grant of patents. Applicants should ensure that the application and supporting documents comply with the applicable statutory and procedural requirements.

Who Can Apply for a Patent in Bangladesh?

A person claiming to be the inventor, or a person legally entitled to apply for the invention, may seek patent protection subject to the requirements of the applicable Bangladesh patent legislation. Applications may involve an individual applicant, joint applicants or an applicant claiming rights through the inventor.

Where a patent application is filed through an authorized representative, appropriate authorization and supporting documents may also be required.

Patent Specification in Bangladesh

The specification is one of the most important components of a patent application. A complete specification should clearly explain the invention and provide sufficient technical information to understand and implement it.

Depending on the invention, drawings, diagrams, claims, abstract and other technical information may be necessary. Careful drafting is essential because the scope of protection is closely connected with the claims and disclosure contained in the application.

Provisional and Complete Patent Specification

Under the current Bangladesh patent framework, an applicant may file a patent application with a provisional specification or a complete specification, subject to the statutory requirements.

Where a provisional specification is filed, the complete specification must be submitted within the applicable statutory period. The Bangladesh Patents Act, 2023 provides a 12-month period for filing the complete specification after filing the provisional specification.

A complete specification should contain a clear description of the invention, relevant technical details, claims defining the invention, an abstract and drawings where appropriate.

Patent Registration Process in Bangladesh

A patent application requires careful preparation and procedural follow-up. The general process may include the following stages, subject to the applicable law and DPDT procedures.

1

Invention Assessment

We review the invention and discuss the technical, commercial and intellectual property aspects relevant to patent protection.

2

Patent Search & Analysis

Where appropriate, a patentability or prior-art search can help identify existing disclosures and assess potential patent risks before filing.

3

Preparation of Patent Documents

We assist with the preparation of the application, specification, claims, abstract, drawings and other supporting documents as required.

4

Patent Application Filing

The patent application is prepared and filed with the relevant authority in accordance with applicable Bangladesh patent procedures.

5

Examination & Prosecution

We monitor the application and assist with examination reports, office actions, amendments, responses and other prosecution matters.

6

Publication, Opposition & Grant

Depending on the application and applicable procedure, publication and third-party opposition processes may arise before the patent is granted.

7

Patent Maintenance

After grant, applicable renewal or maintenance fees and other post-grant requirements should be monitored to preserve the patent rights.
