The Patent licensing in Bangladesh is governed by The Patents and Designs Act enacted in 1911 during the British colonial age, mainly based on the principles laid down in the British Statute of Monopolies, Patents, Design, and Trade Marks Act, 1883 and the Patents and Designs Act, 1907. The laws regulating the patents and designs are, therefore, consolidated in a single enactment, namely, the Patents and Designs Act, 1911. The statute consists of three parts: Part I relates to Patent laws; Part II relates to Design laws, and Part II includes general provisions.
The Department of Patents, Designs, and Trademark (DPT) protect the rights of patent holders for 16 years on payment of a prescribed sum of money.

However, a complete specification must be filed within 9 months from the date of filing of the provisional specification. The complete specification must particularly describe and ascertain the nature of the invention and the manner in which the same is to be performed.
A convention application is an application that is made in Bangladesh within twelve months after the date of an application made in a convention country, whether claiming single or multiple priorities from such application.
In accordance with Section 15A of the Patents & design Act 1911, a patent of addition is a mere improvement or modification of an already filed invention. An application of a patent of addition is not granted before the main invention. No renewal fee is required to be paid for the patent of addition and it expires along with the main invention/patent.
