If you are resident in India, you cannot file a patent application abroad first without either filing in India first or obtaining permission.
Section 39 of the Patents Act, 1970 gives you two routes:
- File in India first, then wait six weeks for any secrecy direction from the Indian Patent Office before filing abroad; or
- Obtain a Foreign Filing Licence (FFL) from the Controller before filing the first application abroad.
One or the other. There is no third option.
Why this exists
The purpose is to ensure inventions originating in India, particularly those with potential defence or security applications, are reviewed domestically before being disclosed internationally.
Several countries have equivalent provisions. India’s is broader than most, as explained below.
It turns on residence, not citizenship
This is the point that causes the most confusion.
The requirement applies to any person resident in India. The Patents Act does not define “resident”, and the term is typically interpreted in line with the Income Tax Act, under which a person is resident where physically present in India for more than 182 days in a financial year.
The practical consequences:
- An Indian citizen living and working abroad is generally not resident in India and does not need an FFL, unless they maintain Indian tax residency.
- A foreign national resident in India does need one. Citizenship is irrelevant.
- Indian citizens residing in India must obtain an FFL before any foreign first filing.
Where an invention has multiple inventors and some are resident in India, the requirement is engaged for those inventors.
It applies to all inventions
Section 39 is not limited to security-sensitive subject matter. It applies broadly to all inventions, regardless of field.
A separate provision, Section 35, empowers the Controller to issue secrecy directions where an invention is relevant for defence purposes. That is a different mechanism. Section 39 catches everything.
Software, consumer products, agricultural methods: the FFL requirement applies the same way it does to anything else.
The six-week route versus the licence
Filing in India first and waiting six weeks is often the simpler path where you intend to file in India anyway. The six weeks runs from the Indian filing date, and you can proceed abroad afterwards provided no secrecy direction has been issued.
The FFL route is what you need where you do not want to file in India first, or where the foreign deadline does not allow six weeks. The application is made to the Controller, and turnaround is usually a matter of weeks rather than days, so it needs planning rather than being left to the eve of a foreign deadline.
What happens if you skip it
The consequences are serious and are frequently underestimated:
- The Indian patent can be revoked or the application deemed abandoned.
- Criminal liability is provided for under the Act.
This is not a formality with a fee attached. It is a prohibition with penalties.
Where this goes wrong in practice
The common scenario is an Indian inventor or start-up working with foreign counsel, typically US or European, who file a provisional in their home jurisdiction as a matter of routine. Nobody asks about Indian residence, the US provisional goes in first, and the FFL requirement has already been breached before anyone thinks about India.
If you are an Indian-resident inventor working with foreign counsel, raise this before anything is filed anywhere. It is straightforward to comply with in advance and difficult to fix afterwards.
The same applies to Indian subsidiaries of foreign companies where the inventors are based in India, and to Indian employees inventing for a foreign parent.
Frequently asked questions
Do I need an FFL if I file in India first? No, provided you wait six weeks from the Indian filing date and no secrecy direction has been issued.
I am an Indian citizen living in the US. Do I need one? Generally no, because the test is residence rather than citizenship. If you maintain Indian tax residency, the position changes.
Does the FFL requirement apply to software inventions? Yes. Section 39 applies to all inventions regardless of subject matter.
How long does it take to get an FFL? Typically weeks rather than days. Plan for it rather than requesting it against a foreign deadline.
What if some inventors are in India and some are not? The requirement is engaged for the India-resident inventors, so it needs addressing before any foreign filing.
What happens if I already filed abroad without one? Take advice quickly. The exposure includes revocation of the Indian patent and criminal liability, and the options narrow the longer it goes unaddressed.
