Section 39 of the Indian Patents Act, 1970, serves as a critical checkpoint for Indian residents looking to protect their inventions globally. Often misunderstood as a mere administrative formality, compliance with Foreign Filing License (FFL) requirements is a substantive legal mandate that directly impacts the validity of an entire patent portfolio. For global R&D teams and Indian startups, navigating the interplay between residency, inventiveness, and secrecy directions is a prerequisite for a sound international filing strategy.
The Statutory Mandate: Section 39 and the Residency Trigger
The obligation to seek a Foreign Filing License is triggered by the residential status of the inventors or the applicant, irrespective of their citizenship or the location where the R&D was conducted.
Defining "Resident in India" for Patent Purposes
The Patents Act does not explicitly define "resident." In practice, the Indian Patent Office (IPO) and the judiciary refer to the definition under the Income Tax Act, 1961. Generally, a person is considered a resident if they have stayed in India for 182 days or more in a financial year.
· Key Strategy: Multinational corporations (MNCs) must track the residency of every joint inventor. If even one inventor is an Indian resident at the time of filing, Section 39 compliance is mandatory.
The Six-Week Deemed Approval Rule
Under Section 39(1)(a), an FFL is not required if the applicant first files in India and waits for six weeks. This period allows the Controller to scrutinize the invention for sensitive subject matter. If no secrecy directions are issued under Section 35 within these six weeks, the applicant is free to file abroad.
Procedural Mechanics of Form 25 and Rule 71
When a "US First" or "PCT First" strategy is preferred for commercial reasons, the applicant must proactively apply for a written permit via Form 25.
Documentation and Disclosure Requirements
A request for an FFL must include a disclosure of the invention that is sufficiently detailed for the Controller to assess whether it pertains to defense or atomic energy.
· Form 25: Includes the title of the invention, name/address of inventors, and a list of target countries.
· Accompanying Disclosure: A brief description of the invention (abstract and claims) is typically sufficient.
· Power of Attorney: Required if the application is filed through a registered patent agent.
Current IPO Timelines (2025–2026)
According to Rule 71, the Controller is mandated to dispose of an FFL application within 21 days. In practice, most routine FFLs are granted within 10 to 15 days. However, inventions that appear to fall within "sensitive" categories are referred to the Ministry of Defence or the Department of Atomic Energy, which can extend the timeline significantly.
Judicial Clarity: The Selfdot Technologies Precedent
The Madras High Court’s decision in Selfdot Technologies (OPC) Pvt. Ltd. v. Controller General of Patents (2023) has provided much-needed clarity on the scope of "any application" under Section 39.
The Patent of Addition vs. Divisional Application Distinction
The core issue in Selfdot was whether a separate FFL is required for a Patent of Addition (or a US Continuation-in-Part) when the parent application already had clearance.
· Divisional Applications: The court noted that because a divisional application must not contain matter beyond the parent disclosure, a separate FFL is generally not required if the parent was cleared.
· Patents of Addition: Because these involve an "improvement or modification" containing new technical matter not disclosed in the parent, the court held that a separate FFL is mandatory for the additional subject matter.
Substantive Infractions vs. Technical Irregularities
The court distinguished between a "substantive" breach (filing a new invention abroad without any Indian clearance) and a "technical" breach (failing to get a separate FFL for an improvement on a cleared invention). While the Selfdot ruling was empathetic to bona fide mistakes in the context of Patents of Addition, it reaffirmed that Section 39 is a mandatory, not directory, provision.
Deemed Abandonment: The Severity of Section 40
Section 40 acts as the "nuclear option" for non-compliance with Section 39. It provides that if a person contravenes Section 39, the Indian patent application for that invention shall be deemed to have been abandoned, and any granted patent shall be liable for revocation.
Irreversibility of Abandonment
Unlike other procedural lapses in the Indian Patents Act, there is currently no provision for retrospective FFL or for condoning a Section 39 violation. Once a foreign filing is made without a license or the six-week wait, the Indian rights are effectively forfeited.
· Business Risk: Investors conducting Due Diligence often flag Section 39 violations as a "fatal flaw" that wipes out the asset value in the Indian market.
Criminal Liability under Section 118
Beyond civil consequences, Section 118 stipulates criminal penalties for the person who "makes or causes to be made" a foreign application in contravention of Section 39.
· Penalties: Imprisonment for a term that may extend to two years, or a fine, or both.
· Enforcement Reality: While criminal prosecution for Section 39 is rare, the mere existence of the provision provides a powerful ground for competitors to challenge the integrity of a patentee’s management.
Cross-Border Strategy: US Provisional and PCT Traps
The "US Provisional" Pitfall
Many startups believe that a US Provisional filing is "private" and therefore exempt. This is legally incorrect. Section 39 applies to "any application outside India." Filing a US Provisional before obtaining an FFL or waiting six weeks after an Indian filing is a direct contravention.
The PCT RO/IB vs. RO/IN Choice
Indian residents filing a PCT application:
· RO/IN (Indian Patent Office): Acting as a receiving office, the IPO performs the Section 39 screening automatically.
· RO/IB (WIPO International Bureau): If filing directly with the IB, the resident must have a pre-existing FFL or have waited the six-week period from a prior Indian filing.

Checklist: Pre-Filing Compliance
· Identify residency of all inventors (182-day rule).
· Verify if the invention involves defense, nuclear, or biological sensitive areas.
· If filing abroad first, file Form 25 and wait for the written permit.
· If filing in India first, track the 42-day (6-week) "no-go" period before foreign dispatch.
· For improvements/modifications, assess if new matter requires a fresh FFL (as per Selfdot).
Frequently asked questions (FAQs)
1. Does a non-Indian citizen living in Bengaluru need an FFL?
Yes. Section 39 is based on residency, not nationality. If you reside in India, you are bound by the provision.
2. Can I apply for an FFL after I have already filed in the US?
No. There is no provision for a retroactive FFL in India. A violation is considered complete the moment the foreign application is "caused to be made."
3. Does the FFL requirement apply to design patents?
No. Section 39 is located within the Patents Act. The Designs Act, 2000, does not have an equivalent mandatory foreign filing license provision.
4. What if the applicant is a US company but the inventor is in India?
The Indian resident inventor is "causing the application to be made" abroad. Therefore, an FFL must be obtained by the Indian inventor or on their behalf by the applicant.
5. How much is the official fee for Form 25?
As of 2025-2026, the fee is approximately ₹1,600 for individuals/startups and ₹8,000 for large entities.
6. If I file a PCT application at the Indian Patent Office, do I still need a separate FFL?
No. Filing a PCT at the IPO (as Receiving Office) satisfies the requirement, as the Controller will screen it before transmitting it to the International Bureau.
7. Does the Selfdot case apply to PCT National Phase entries?
No. National Phase entry is generally considered a continuation of the original PCT filing. However, if you are adding new matter during the National Phase (which is rare and limited), you must be cautious.
8. Can a Section 39 violation be cured during the opposition stage?
No. Section 40 clearly states that the application "shall be deemed to have been abandoned." It is a statutory bar that cannot be waived by the Controller or cured by the applicant.
9. Is an FFL required for a "continuation" application in the US?
If the continuation contains the exact same disclosure as the parent (which was already cleared), a new FFL is typically not required. If it is a "Continuation-in-Part" (CIP) with new matter, an FFL is mandatory for that new matter.
10. What is the "Secrecy Direction" mentioned in Section 35?
It is an order from the Controller prohibiting the publication or communication of an invention that is relevant for defense purposes. An FFL is the mechanism to ensure such directions are not bypassed.
