History of Patenting in Bangladesh

The Patents, Designs, and Trademarks Act of 1883 were the first piece of legislation to be discovered in Bangladesh to protect IP. The Trademarks Act of 1940 and the new Patents and Designs Act of 1911, respectively, were passed after it was repealed. Then, in 2003, all of these Acts were revised, and the Departments of Patents, Designs, and Trademarks (DPDT) were established by joining the Patent Office and the Trademark Registry Office, two independently operating departments. After the Trademarks Ordinance was published in 2008, the Trademarks Act 2009 was passed. The British Copyright System and the Copyright Ordinance, which was enacted in 1962 after several Copyright Laws were combined, are the sources of the copyright system in Bangladesh. Following the implementation of this Ordinance till 1999, the Copyright Act was enacted in 2000 and amended in 2005.
