Know About Patent

Updated: Jun 18


  • What is Patent?

Patent is a form of Intellectual Property that can be obtained for any new invention or technology capable of industrial application. This invention may be a product or a process which is previously not filed for patent protection or used in the country or elsewhere in the world. The person who owns the patent is called the “Patentee”. The major requirements that need to be fulfilled for obtaining patent includes, novelty, utility and non-obviousness (also called the NUNS test). The duration of patent protection is twenty years from the date of application and is territorial in nature. The patent system in India is governed by the Patents Act, 1970 and the Patent Rules, 2003.


  • Who can file a patent application?

The following can make a patent application:

1. Any person who is supposed to be the true and first inventor of the product/process.

2. Any person to whom the true and first inventor has assigned the rights to.

3. In case the inventor is deceased, his legal representative.

However, a joint application with any other person (includes any company or association or body of individuals) is also allowed.
