Which of India's four filing offices should I file my patent application with?

India's four filing offices are in Kolkata, New Delhi, Mumbai and Chennai. Each has a separate territorial jurisdiction. Where you file your application depends on

  • where you live
  • where your business is located, and
  • where the invention actually originated.

For foreign applicants without a place of business or address in India, the territorial jurisdiction is defined by the address or place of business of their patent agent.

To find out more about the territorial jurisdiction of the four offices in India, see the Jurisdiction of patent offices section on the Indian Patent Office's (IP India) website.
