The Patent Rules 2003 contain procedural provisions for patent registration. 

The basic steps for filing a patent application in India are as follows: 

  • Search for prior art: A search for prior art is conducted to ensure that the invention is new and has not been anticipated by any earlier publication
  • Prepare the application: The application must contain a description of the invention, one or more claims, and an abstract
  • File the application: The application is filed with the Patents Office along with the prescribed fees
  • Examinations: Once the application is filed, it is examined to ensure that it complies with all formal requirements and that it describes a new invention, novel, and non-obvious
  • Publication: After examination, if the invention is found to be patentable, it is published in the Patents Office Journal
  • Grant of patent: Once the application is published, any interested party may oppose the grant of a patent within six months from publication. A patent will be granted if no oppositions are filed or if any oppositions are unsuccessful.
