Typed of Patent Applications in Bangladesh

What are the different types of applications in Bangladesh and how to file Patent applications in Bangladesh?

Patent applications can be filed in Bangladesh as:

a) Ordinary Application

An ordinary patent application is the application, which is filed with the Bangladesh Patent Office without claiming priority from any other application under process with any other Patent Office.

b) Provisional and Complete Application

A provisional specification is often the first application to be filed in respect of an invention. It usually contains only a brief description of the invention and need not contain claims. 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.

c) Convention Application

The 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.

d) Patent of addition

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 patent of addition is not granted a patent 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. However, if the main patent is revoked, then the patent of addition may be converted into an independent patent on request of the applicant(s). Under such circumstances, same renewal fee must be paid as if the patent has been originally granted as an independent patent.
