Somewhere right now, a competitor may be paying Google to show its advertisement whenever customers search your brand name. Whether that stays lawful in India is being decided in a Delhi High Court appeal that Google itself says could change how search advertising works: the Hindware keywords matter, in which the court ruled against the platform and a division bench issued notice on Google's appeal on 10 July 2026. The same week produced a second development every brand owner should know: the 'Ghostbuster' ruling, holding that a mark does not need a formal "well-known" declaration to receive protection across product classes. This guide explains the law of keyword advertising and trademark use in India, what the two July 2026 developments change, how well-known mark protection actually works under Sections 11 and 2(1)(zg) of the Trade Marks Act, and the concrete monitoring-and-enforcement playbook for a brand of any size.
Key takeaway: while the keyword question is on appeal, the winning move for brand owners is evidence and registration, not waiting. Search your own brand in an incognito window this week, screenshot rival ads with dates, and make sure your registrations cover the classes you trade in. Whatever the division bench decides, documented goodwill wins cases; undocumented indignation does not.
How keyword advertising collides with trademark law
Search-engine advertising lets any advertiser bid on any search term, including a rival's registered trademark. The customer types a brand they trust; the results page serves them the competition, marked "Sponsored", above the organic result they were looking for. The trademark questions this raises under Section 29 of the Trade Marks Act, 1999 are three:
- Is bidding on a mark as an invisible keyword "use" of the mark "in the course of trade" and "in advertising" under Sections 29(6) and 29(8)?
- Does it cause the confusion, or take the unfair advantage of repute, that Sections 29(2) and 29(4) prohibit?
- And what is the platform's own responsibility, as the seller of the keyword, when a proprietor complains?
Indian courts have circled these questions for years. The Delhi High Court's DRS Logistics (Agarwal Packers) litigation against Google established that use of registered trademarks as ad keywords can amount to "use" under the Act and that the platform cannot simply disclaim responsibility when infringement is shown; the court required complaints to be investigated rather than deflected. The Hindware matter pushed the line further against the platform, and it is that ruling Google has now appealed, telling the appellate bench the decision could change how search ads work in India. The appeal is pending; no prediction belongs in print. What can be said is that the direction of Indian authority has been steadily more protective of proprietors than the position advertisers assume.
The 'Ghostbuster' ruling: cross-class protection without the formal tag
Trademark registration is organised into 45 classes of goods and services, and protection ordinarily runs class by class: registering a mark for software does not by itself stop a mattress company using the same word. The great exception is the well-known mark. Under Section 2(1)(zg) and Section 11(2), a mark whose reputation is such that use on unrelated goods would suggest a connection gets protection across classes, and Rule 124 of the Trade Marks Rules, 2017 even created a formal procedure to have a mark declared well-known and entered on the registry's list.
The July 2026 'Ghostbuster' decision of the Delhi High Court answered the question that procedure created: is the formal declaration a precondition? No. A court can extend cross-class protection on reputation proved in evidence, without the mark ever having been through the Rule 124 process. Two practical consequences flow in opposite directions:
- For established brands: your protection may already reach further than your registrations. Sales figures, advertising spend, media coverage and consumer recognition, proved properly, can stop a free-rider in a class you never registered in.
- For new brands choosing names: a clearance search limited to your own class is no longer enough. The name you are about to adopt may collide with a reputation registered nowhere near your class, and "their registration is in class 9, we are in class 25" is not the safe harbour founders assume.
Infringement vs passing off: which case are you actually filing?
| Infringement (S.29) | Passing off (common law) | |
|---|---|---|
| Requires registration? | Yes, in the relevant class (or well-known status for cross-class reach) | No; protects goodwill itself |
| What is proved | Use of an identical/deceptively similar mark; confusion or unfair advantage | Goodwill + misrepresentation + damage (the classical trinity) |
| Strength | Statutory presumptions; faster interim relief | Heavier evidentiary lift, but reaches unregistered marks |
| Keyword cases | The "use in advertising" argument under S.29(6)/(8) | Available in parallel where confusion or diversion is shown |
Most serious brand suits plead both. If your mark is unregistered, passing off is your only sword, which is itself the strongest argument for registering now rather than after the fight starts. Our practice-side overview of registration strategy, classes and enforcement sits in the standing guide to trademark infringement in India; this article extends it into the keyword and well-known-mark battlefield of 2026.
The brand-owner playbook while the appeal is pending
- Audit your brand's search results monthly. Incognito window, your brand name and its misspellings, screenshots with visible dates and URLs. Many owners discover the problem months and lakhs late.
- Register properly: the classes you trade in, the classes you are expanding into, the word mark and the logo separately. Enforcement arguments start from registration certificates.
- Use the platform's own complaint route first. Google maintains a trademark complaint process for ad text; after DRS Logistics, complaints that go uninvestigated build your case against the platform as well as the advertiser.
- Cease-and-desist through counsel to the advertiser, with your evidence annexed. Many keyword campaigns are agency defaults, not strategy; a well-drafted notice ends a surprising number.
- Sue where it matters: where a rival's keyword campaign is diverting a measurable customer flow, an infringement and passing-off suit with an interim injunction application is the real remedy, and the interim stage is usually the whole war.
- Preserve reputation evidence continuously: sales by year, ad spend, press, awards, follower counts. After 'Ghostbuster', this file is what cross-class protection is made of, and it cannot be assembled retrospectively in a hurry.
Common mistake: founders treat the trademark as a one-time registration formality and the brand's Google results as the marketing team's problem. The two files are the same file. In every keyword dispute I have seen, the side with twelve months of dated screenshots and a tidy registration portfolio dictated the settlement; the side with neither paid for its tidiness retrospectively, in court fees.
What this means for advertisers, too
The mirror image deserves a paragraph, because half the businesses reading this also buy ads. Bidding on a competitor's brand name is now contested legal territory in India: the ruling under appeal went against the practice, and even the more permissive line of cases never protected ad text that uses a rival's mark or creates confusion about who you are. If your agency is running competitor-brand campaigns, have them reviewed now: keyword lists, ad copy, and landing pages, against both Section 29 and the pending appeal's likely outcomes. An injunction plus damages plus the diversion of your own management time is a high price for borrowed traffic.
Frequently Asked Questions
Is it illegal in India for a competitor to bid on my brand name in Google Ads?
It is contested territory before the Delhi High Court: the Hindware ruling went against the practice and Google's appeal is pending, with notice issued on 10 July 2026. Earlier authority (DRS Logistics) already treats keyword use of marks as "use" under the Act. Document instances and take advice before acting.
What can I do right now if rivals advertise on my brand searches?
Screenshot the ads with dates, complain through the platform's trademark process, send a cease-and-desist through counsel, and evaluate an infringement/passing-off suit with interim relief if diversion is significant.
What is a well-known trademark?
A mark with such reputation that its use on unrelated goods suggests a connection with the owner, protected across all 45 classes under Sections 2(1)(zg) and 11. Recognition comes either through the Rule 124 declaration process or, after the July 2026 'Ghostbuster' ruling, through reputation proved in court.
Does my mark need to be on the registry's well-known list for cross-class protection?
No. The Delhi High Court held in July 2026 that formal declaration is not a precondition; reputation proved in evidence can support cross-class protection on its own.
Can I sue if my brand is not registered?
Yes, in passing off, by proving goodwill, misrepresentation and damage. It is a heavier evidentiary lift than infringement, which is why registration first is always the cheaper path.
Which classes should I register in?
The classes covering what you sell today and what you will plausibly sell next, word mark and logo separately. Trading into three classes while registered in one is how disputes begin.
Is using a competitor's name in ad text different from bidding on it as a keyword?
Yes, and worse. Even the cases most permissive on invisible keyword bidding draw the line at ad text that uses a rival's mark or confuses consumers about the advertiser's identity.
How long does trademark registration take in India?
Typically 8 to 18 months if unopposed, with protection relating back to the application date. Filing is online through IP India's portal.
