Quick answer

Under Section 39 of the Patents Act, a resident of India must not file a patent application for an invention outside India unless it was filed in India at least six weeks earlier with no secrecy direction, or the Indian Patent Office has given written permission on Form 25. The Controller ordinarily decides a Form 25 request within 21 days. CorpBridge's professional fee is ₹4,999 plus GST and the official fee.

What is Foreign Filing Permission?

Indian residents, including Indian companies whose inventors are abroad, need clearance before filing a patent application outside India. There are two ways: file in India first and wait six weeks, or apply for written permission on Form 25 if you need to file abroad sooner or without an Indian filing.

Skipping this step is serious. Under Section 40, an Indian application can be treated as abandoned and a granted patent can be revoked, and Section 118 provides for imprisonment of up to two years, a fine, or both. We prepare the request with a clear description of the invention so that permission is not delayed.

Frequently asked questions about Foreign Filing Permission

Who needs foreign filing permission in India?

Any person resident in India who wants to file a patent application for an invention outside India without first filing in India and waiting six weeks. Residence, not nationality, is the test, and Indian companies count as residents.

Do I need permission if I filed in India first?

Not if at least six weeks have passed since the Indian filing and no secrecy direction has been issued. Before that, you need Form 25 permission.

What happens if I file abroad without permission?

Your Indian application can be treated as abandoned, a granted patent can be revoked, and Section 118 provides for imprisonment of up to two years, a fine, or both.

The Controller ordinarily decides within 21 days. Inventions relating to defence or atomic energy need Central Government consent and can take longer.
