- Patent Application Filing and Registration in Bangladesh
Patents in Bangladesh are essential for inventors, entrepreneurs, and businesses to secure their intellectual property. Governed by the Bangladesh Patent and Design Act, the system ensures legal protection for inventions, utility models, and designs. Filing a patent application in Bangladesh gives innovators exclusive rights to use, manufacture, or sell their creations in the country.
Bangladesh, as an emerging technology and industrial hub in South Asia, has been strengthening its intellectual property regime to encourage innovation, protect inventors, and attract foreign investment. Understanding the patent system is crucial for local and international businesses looking to operate or expand in Bangladesh.
The Bangladesh patent system works on a first-to-file principle, meaning the first person to submit a valid patent application in Bangladesh is granted rights, regardless of who created the invention first.
