Documents required for filing Patent in India

The origin of the word ‘patent’ can be traced from the Latin word ‘patere’, which means ‘to open'; if a natural person or an artificial entity believes that it has made an invention with novelty and utility. In that case, it may ask the Government by filing an application in the Patent Office to grant a document that states what the invention is and that such person is the owner of the patent. This document issued by the government authority is called a patent or a patent for invention. Patent filing in India is regulated and governed by the Patents Act, 1970.

How to apply for a Patent in India?

Patent filing in India starts by submission of application in Form 1 in the patent office having jurisdiction. Along with the application, a complete/provisional specification has to be filed using Form 2. However, in the case of convention application, the only complete specification can be filed. Then the process moves onto an examination of application then advertisement of acceptance of complete specification. If there is any opposition to the grant of a patent to the applicant, then parties are heard. Finally, if the decision favors the applicant, the patent granted is sealed with the patent office seal.
