A patent is a form of intellectual property that, upon payment of the required fees, grants its owner or inventor the legal right to prevent third parties from creating, using, or commercializing the invention for 16 years. This period of protection may be extended.

Any citizen of Bangladesh or foreign national may apply for a patent individually or jointly under Section 3 of the Patent & Design Act, 1911. The application must be submitted to the Department of Patents, Designs, and Trademarks (DPDT) using the forms provided. The inventor’s application must include a statement attesting to the applicant’s ownership of the patent. In a joint application, the full specification must be annexed by one of the applicants—claiming to be the legitimate and first inventor—or by that applicant’s legal representative or assign.

A provisional (Form-3) or complete (Form-3A) specification must be submitted with a patent application (Form-1). Within nine months of the date that Forms 1 and 3 were submitted, a complete specification must be submitted if any applicant submitted a patent application with a provisional specification. If Form-3A is not submitted, the primary patent application will be deemed to have expired. A comprehensive specification must contain the inventor’s name, address, invention title, abstract, synopsis, description, drawing outlining the nature and method of the invention’s execution, and claims outlining the invention’s scope for which the inventor seeks protection.

Following submission, the aforementioned applications are forwarded to an examiner who has been recommended for review by the patent registrar. The application is then published in the Gazette if the examiner has no objections. The Registrar is required to issue patent letters if no opposition is received. Additionally, in compliance with the patent regulations, the patentee must file Form 8 along with the required fee if they wish to have their patent sealed.
