Patent Law

A patent is a form of intellectual property. The person who has patented his work enjoys the protection of his invention from anyone to make, use, sell such invention for a limited period of time.

With the development of inventions, the inventors want to make their rights on their work to be exclusive. To do such the inventor has to get his work patented.

Patent law sees itself way back in 1911 when it was enacted, known as the Indian Patents & Designs Act, 1911. A new actis is known as the Patents Act, 1970 which was brought into effect by amending the old act. The present article will enlighten on the area of how the patent law works in India in safeguarding inventions of the inventors.


What is a Patent?

The word Patent refers to a monopoly right that an owner gets for an invention that is conducted by him. Not all inventions are patent-able in nature nor it is essential to protect inventions solely through patent.


What is the object of Grant of Patent?

The object of the grant of Patent is to encourage research and development and innovation and to also provide protection to inventions.


What is the Time Period for which Patent is granted?

Initially, the Act provided for a shorter term for the protection of medicine or drug substances. However, after the Amendment Act of 2005 came into effect the uniform period of 20 years was fixed for all the Patents. Thus, once the prescribed period of 20 years is over, then any person can exploit the patented invention i.e. the invention will become public property. The term of a patent begins from the date of application of patent Just like in the case of a patent.


What are the requirements for a Grant of Patent?

  1. The application for grant of Patent shall be filed at the Indian Patent Office.
  2. Any person whether an Indian or a Foreigner, individual or a company, or the Government can file a Patent Application.
  3. The person who is applying for a Patent shall be the true and first inventor of the invention proposed to be patented.
  4. The patent application can also be made jointly.
  5. The patent application shall primarily disclose the best method of performing the invention known to the applicant for which he is entitled to claim protection.
  6. The applicant shall also define the scope of the invention.
