The campaign went live on a Friday. ₹30 lakh in influencer spend, a hashtag on every post, and by Sunday the tag was trending. By Wednesday, three competitors were running paid ads against the same hashtag.
The brand's lawyers asked one question: is the hashtag registered? It was not. The campaign had built an audience — and the audience belonged to everyone.
Hashtags can be trademarks in India, but only when they work as brands rather than conversation labels. Here is where that line sits, what survives examination, and what you can actually enforce when someone hijacks your tag.
The law has no hashtag section. It doesn't need one.
The Trade Marks Act, 1999 says nothing about hashtags, and that is the point. The test is the same one every mark faces under Section 2(1)(zb): can it be represented graphically, and can it distinguish your goods or services from everyone else's? A hashtag is simply a word or phrase with a # in front.
So #YourBrand is registrable exactly to the extent "YourBrand" is. The # symbol itself adds nothing — examiners treat it the way they treat "www." or ".com", as furniture that cannot make a weak word strong.
That cuts both ways. If your brand name is distinctive, the hashtag version rides on its strength. If the phrase after the # is generic or descriptive, no symbol rescues it.
The # is decoration. The word inside it is the trademark — or isn't.
Source identifier or conversation label? The only test that matters
A trademark identifies commercial source. A hashtag organises conversation. The same string of characters can do either job, and registrability follows the job it actually does.
A tag used for one festive campaign and retired is decoration — consumers read it as a topic, not a seller. A tag that appears on packaging, in the Instagram bio, on the storefront and across campaigns for years starts to function as a brand.
- Continuity. The tag runs across campaigns and seasons, not one burst of media spend.
- Placement. It appears on product, packaging and invoices — not only in captions.
- Exclusivity. Consumers associate it with you alone, not with a community or a topic.
- Recall. People search the tag to find your products, not to browse a genre.
If you can honestly tick three of those four, you have a mark wearing a hashtag. Register the mark.
The Section 9 filter kills descriptive hashtags
Section 9(1) refuses marks that lack distinctive character or that merely describe the goods. The examiner reads your hashtag with the # stripped off. #PureHoney for honey fails. #FreshFarmEggs for eggs fails. #BestPriceMobiles for a phone store fails twice.
What survives is what always survives: coined words, arbitrary combinations, and suggestive phrases that hint without describing. A made-up word with a # in front examines exactly like a made-up word.
Community tags are the other dead end. #OOTD, #Foodie, #WeddingSeason are customary in current usage — the whole market speaks them, so no trader can own them. Filing them buys you an objection, not an asset.
If the whole industry could caption with it, you cannot own it.
Tagline or hashtag? Register the words.
Most branded hashtags start life as campaign taglines. The efficient move is to register the tagline as a wordmark, without the #. Infringement under Section 29 covers identical and deceptively similar signs used in trade — and a registered tagline is infringed whether the copyist writes it plain, in title case, or behind a hash symbol.
Filing both the plain and hashtag versions is rarely necessary. File the words; keep dated screenshots of the hashtag in use as evidence of reputation.
One class-selection trap: founders reflexively file hashtags in Class 35 because it "covers advertising". Class 35 covers advertising services provided to others — an agency's business, not yours. Your branded hashtag belongs in the class of the goods or services it sells: Class 25 for the apparel brand, Class 30 for the coffee, Class 41 for the course.
Hashtag hijacking: what you can and cannot stop
Hijacking arrives in three shapes: competitors running paid ads on your branded tag, counterfeiters tagging fakes so your customers find them, and ex-partners or resellers trading on the tag after the relationship ends.
With a registration, you have real leverage. Competitor use of your mark in the course of trade, in a way that confuses buyers, is infringement under Section 29 — hashtag or not. Counterfeit listings fall to marketplace and platform IP complaints, and Meta, X and Amazon brand programmes all move faster when a registration certificate number is attached. Without a registration you are left with passing off — winnable with strong goodwill evidence, but slower and costlier, usually through IP litigation.
What you cannot stop: genuine users tagging honest conversation, reviews or criticism. The Act protects honest descriptive use, and courts will not let a trademark silence customers. Enforcement targets trade use, not talk.
You cannot own the conversation. You can own your name inside it.

Vet my hashtag before launch →The hashtag playbook, from search to enforcement
- Search before you seed. Check the registry for the phrase with and without the #, plus phonetic variants, and scan the platforms for prior users. A trademark search and watch service covers both in one pass.
- File the wordmark on TM-A. The plain-word version, in the class of your actual goods or services — ₹4,500 per class for startups and MSMEs. The full process is mapped in our guide to trademark registration in India.
- Use it like a brand. Bio, packaging, repeated campaigns. Archive dated screenshots quarterly — they become your evidence of distinctiveness.
- Watch the journal. If someone files a lookalike, you have 4 months from publication to oppose the application.
- Enforce in tiers. Platform complaint first, legal notice second, suit last. Most hijackers fold at tier one when a certificate is attached.
- Protect the campaign creative separately. The film, artwork and copy behind the hashtag are protectable through copyright registration — a different right that covers what the trademark cannot.
A trending hashtag is rented attention. A registered one is owned ground.
Hashtags die in a season; brands compound for decades. Decide which one you are building before the media budget clears, and file the words while they still cost ₹4,500 a class.
Your brand is only yours when you file it.
