When you claim prior use of a trademark in India, the law asks for an affidavit and supporting evidence — but it never says exactly what evidence is enough. That gap is where applications are won or lost.
The rule, and the gap
Where an applicant claims use of a mark, the Trade Marks Rules, 2017 require an affidavit testifying to that use, together with supporting documents. What the Rules do not do is set a standard of proof — there is no prescribed list of documents that guarantees acceptance.
In practice, many hearing officers have come to expect sales invoices specifically, even though neither the Act nor the Rules single out invoices as mandatory. For an established manufacturer that is manageable. For a digital-first business — one whose “use” lives on an app, a marketplace listing or social channels — insisting on traditional invoices can be unreasonable and out of step with how brands are actually used today.
What to put in front of the hearing officer
Because India is a common-law jurisdiction where use creates rights, the strength of your evidence often decides both registration and later enforcement. Build the fullest possible record:
- All available sales invoices — the document officers most often expect. Include them where they exist.
- Dated materials prominently showing the mark — packaging, labels, catalogues, advertisements, each with a clear date.
- Government documents or media coverage referencing the mark, which carry independent weight.
- Licensing or distribution agreements showing commercial use of the mark.
- A clear record of any change in the mark’s ownership or title, set out in the affidavit so the chain of use is unbroken.
- Digital-era evidence — social media presence, e-commerce listings, app-store pages, website archives and brochures — to establish use where a business operates primarily online.
How to present it
- Tie every document to a date and, where possible, to India.
- Lead with the strongest independent evidence (media, government records) rather than relying on invoices alone.
- Make the affidavit narrate the story — first use, continuity of use, and any change of ownership — with the documents cross-referenced as exhibits.
Frequently asked questions
Is a sales invoice mandatory to prove use? No. Neither the Act nor the Rules require invoices specifically, though many hearing officers expect them. Other dated, mark-bearing evidence can carry the claim.
How can an online-only business prove use? Through e-commerce listings, app-store pages, dated social media activity, website archives and advertising — all showing the mark in use over time.
Is there a fixed standard of proof of use? No. The Rules require an affidavit and supporting documents but set no prescribed standard, so the quality and breadth of evidence matters.
Why does proof of use matter so much in India? Because rights flow from use in a common-law system — good evidence supports registration and is decisive in opposition and enforcement.
