What is patent registration?

If a person invents a product or device or anything and he doesn’t want anyone to make, use or sell his invention then he needs to do patent registration for his invention as per the patents and designs Act 1911.

 

Why patent registration is necessary?

By doing patent registration, an inventor will get the sole right to exclude others from making, using, or selling his invention.

How many types of patent registration are there?

 

There are two types of applications for patent registration.

  1. One is an Ordinary application. This application was filed in Bangladesh Patent Office and it did not claim any priorities.
  1. Another one is the Convention application which claims single or multiple priorities from an application made in a convention country but it has to be made within 12 months of the application that was made in the convention country.

What are the basic requirements of patent registration?

 

  1. The application must contain an invention.
  2. The applicant must be in possession of that invention.
  3. The applicant must be the first inventor or the legal representative or assigned of the such inventor.
  4. Where the true and first inventor is not the applicant, the application must contain a statement of his name, and such particulars for his identification and the applicant must show that the applicant is the legal representative or assign of the such inventor.
