How to Oppose a Trademark in India: Form TM-O Procedure, Grounds & Timeline (2026)

Last verified: 2026-06-11

A pharmaceutical major once filed a trademark opposition in India with everything going for it: a well-known mark, a genuine likelihood of confusion, and a rival application that looked very much like a free ride on its goodwill. It still lost. Not on the merits, but on a calendar. It filed its supporting evidence affidavit a few days outside the two-month window that Rule 45 allows, and asked the Registrar to overlook the slip. In Sun Pharma Laboratories Ltd. v. Dabur India Ltd., C.A.(COMM.IPD-TM) 146/2022 (Delhi HC, 2024), the Delhi High Court’s Intellectual Property Division gave a blunt answer: the Registrar has no power to extend that window. The deadline was mandatory. The opposition fell.

That ruling captures the one truth most guides bury. In a trademark opposition, the clock, not always the merits, decides who keeps the brand.

Here’s why that matters to anyone watching the Trade Marks Journal. Every stage of an opposition runs on a hard statutory clock. Miss the four-month window after a mark is advertised and you lose the right to oppose at all. Miss the two-month counter-statement deadline as an applicant and your application is deemed abandoned. Miss the Rule 45 evidence date as an opponent and your opposition is deemed abandoned. These aren’t soft targets a friendly officer can push back for you. They’re statutory cut-offs, and the Sun Pharma ruling confirmed it in the harshest possible setting: a strong case lost to a few late days.

Brand owners learn this the expensive way. A startup spots a near-identical mark advertised in the Journal, sits on it for a quarter while it “decides,” and discovers the four months have run. A trademark agent files a textbook opposition, then forgets that the evidence stage has its own non-extendible clock. The pattern repeats across the Registry: marks lost to missed dates far more often than to weak arguments. The practitioners who win oppositions aren’t necessarily the ones with the best grounds. They’re the ones who diary every deadline the day it starts.

So this guide walks through the entire Form TM-O process end to end. You’ll get the grounds you can actually run, every evidence stage with its deadline and its consequence, the real government fees, a consolidated timeline table, the 2024 to 2026 legal changes that competitors haven’t caught up with, and the appeal route now that the IPAB is gone. You’ll also get something no competitor pairs with this depth: an annotated sample notice of opposition you can model your own draft on. Get the procedure right, and a missed deadline stops being the thing that decides your case.

Here’s the short version before the detail.

Trademark opposition in India is the formal challenge to a trademark application once it is advertised in the Trade Marks Journal. Any person may file a notice of opposition on Form TM-O within four months of advertisement, citing grounds under Sections 9, 11, 18 or 21 of the Trade Marks Act, 1999. The government fee is ₹2,700 per class (e-filing).

What follows covers the full procedure, the fees, the stage-by-stage timeline table, the grounds, the landmark rulings, the 2024 to 2026 changes, and a 16-question FAQ. Start with the Table of Contents and jump to whatever you need.

What is trademark opposition in India?

Picture a Bengaluru candle-maker who has built a small but loyal following under a distinctive name. One morning, scrolling the latest Trade Marks Journal, the founder spots a near-identical mark advertised by a rival in the same class. The application hasn’t registered yet. It’s been accepted and advertised, which means it sits in a public window during which anyone who objects can say so. That window is what a trademark opposition in India exists for.

Opposition is the formal challenge to a trademark application after the Registrar has accepted it and advertised it in the Trade Marks Journal but before it proceeds to registration. It is governed by Section 21 of the Trade Marks Act, 1999. The challenger files a notice of opposition on Form TM-O within four months of the advertisement, sets out the grounds, and the Registry then runs an adversarial process: counter-statement, evidence on both sides, and a hearing before the Registrar decides.

Think of it as the public’s checkpoint. Examination is the Registrar’s own filter, where an examiner raises objections before acceptance. Opposition is the third-party filter that comes after, where the people most affected (existing brand owners, prior users, competitors) get to weigh in before a monopoly is granted. The short answer to why it exists? Registration confers exclusive rights, and the law gives the market a chance to object before those rights crystallise.

Trademark objection vs trademark opposition: what’s the difference?

People use these two terms interchangeably, and they shouldn’t. The difference is who raises the challenge and when.

A trademark objection is raised by the Trade Marks examiner during examination, before the mark is advertised. It comes in the examination report and usually cites Section 9 or Section 11 concerns. You respond to it with a reply to the examination report, and if the examiner is satisfied, the mark proceeds to advertisement. A trademark opposition, by contrast, is raised by a third party after advertisement, on Form TM-O. One is internal to the Registry’s own scrutiny; the other is an outsider stepping in. So if you’ve received an “objection,” you’re dealing with the examiner, not an opponent, and the route forward is a reply, not a counter-statement.

Why opposition matters: protecting a brand before registration

What happens if nobody opposes a mark? It sails through. After the four-month window closes with no opposition filed, the Registrar proceeds to register the mark, and the applicant gets exclusive rights across the class. That’s the whole point of advertisement: silence is treated as the market’s consent.

For a brand owner, that’s exactly why vigilance matters. Opposition is far cheaper and faster than the alternative, which is challenging a registered mark later through rectification under Section 57. The practical reality is that a four-month opposition costs a fraction of a post-registration cancellation fight, both in fees and in time. (We’ll break down that comparison in a dedicated section below.) Catch the conflicting mark in the Journal, and you stop the problem before it becomes a registered right you have to dismantle.

Who can file a trademark opposition?

Here’s a question that trips up business owners constantly: do you need your own registered trademark to oppose someone else’s? The instinct is to assume only registered proprietors have standing. The law says otherwise, and that single fact opens opposition to a far wider group than most people expect.

Section 21(1) of the Trade Marks Act, 1999 uses the words “any person.” Not “any registered proprietor,” not “any prior applicant.” Any person may give notice of opposition. The opponent doesn’t have to show they own a competing registration, that they’ll suffer specific harm, or even that they’re in the same trade. The “any person” standard is deliberately broad because opposition is meant to surface objections in the public interest, not only to protect existing registrants.

That breadth is genuine, but it isn’t a free pass. While anyone can file, the opposition still has to rest on a recognised ground. You can’t oppose a mark simply because you dislike the applicant. You need a Section 9, Section 11, Section 18 or Section 21 basis, and you need to plead it properly. So the gate is wide on standing and narrow on substance.

Can you oppose without owning a registered trademark?

Yes, and this is the part that surprises non-lawyers most. A prior user with no registration at all can oppose. So can a company that operates only abroad but has a reputation in India. So can a consumer-interest objector challenging a deceptive or scandalous mark under Section 9.

In practice, the strongest oppositions still come from parties with something concrete to point to: a prior-used mark, an earlier application, a well-known mark, or demonstrable goodwill. A common question practitioners raise is whether an unregistered prior user really stands a chance against a later applicant. They often do, because the Act protects prior use, and passing-off principles run alongside the registration system. The mistake we see most often is a prior user assuming they have “no rights” because they never registered, then watching a copycat register the mark unopposed.

Can multiple parties oppose together?

They can, and sometimes they should. Where two or more parties share a grievance against the same application (say, a prior user and a licensee, or two members of an industry body), nothing stops them from filing oppositions. Each opposition is processed on its own record, though the Registrar may hear related oppositions together for efficiency.

The practical tip here is about cost and control. Filing separately preserves each party’s independent grounds and evidence, but it multiplies fees and can fragment the argument. Coordinating the pleadings, even when filing separately, usually produces a cleaner, stronger challenge than two disconnected oppositions pulling in different directions.

Grounds for trademark opposition under the Trade Marks Act, 1999

You can have perfect standing and still lose if you plead the wrong ground. This is where most self-filed oppositions go wrong: they assert that the rival mark is “similar” without anchoring that to a statutory basis, and the Registrar has nothing concrete to act on. The grounds for trademark opposition fall into two big families: absolute grounds under Section 9, which look at the mark itself, and relative grounds under Section 11, which look at the mark against earlier rights. Get the family right, and the rest of the argument writes itself.

Why does the distinction matter so much? Because the two families ask completely different questions. Absolute grounds ask: is this mark even capable of being a trademark? Relative grounds ask: does this mark clash with someone else’s earlier mark? A descriptive word like “Sweet” for confectionery fails on absolute grounds no matter who else is in the market. A perfectly distinctive coined word can still fail on relative grounds if it’s confusingly close to an earlier registration. You often plead both, but you plead them as separate, clearly labelled grounds.

Absolute grounds: Section 9 (descriptive, non-distinctive, deceptive marks)

Section 9 of the Trade Marks Act, 1999 sets out the absolute grounds for refusal, and they’re about the mark’s inherent qualities. A mark can be opposed under Section 9 if it’s devoid of distinctive character, if it consists exclusively of marks that describe the kind, quality, quantity or geographical origin of the goods, or if it has become customary in the trade. Section 9 also bars marks that are deceptive, scandalous, or likely to hurt religious sentiments.

Think of it this way. If you’re opposing a mark that’s really just a description dressed up as a brand (“Fresh” for vegetables, “Reliable” for couriers), Section 9 is your ground. The proviso matters too: a descriptive mark can survive if it has acquired distinctiveness through use, so a Section 9 opposition often turns into a factual fight over whether the applicant’s mark has actually built a secondary meaning in the public’s mind.

Relative grounds: Section 11 (likelihood of confusion, similar or identical marks)

Section 11 of the Trade Marks Act, 1999 is the workhorse of opposition practice. It bars registration where, because of identity or similarity with an earlier mark and identity or similarity of the goods or services, there exists a likelihood of confusion on the part of the public. This is the classic “your mark is too close to mine” ground.

The test for deceptive similarity isn’t a casual side-by-side comparison. In Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd., (2001) 5 SCC 73, the Supreme Court laid down a multi-factor approach: the nature of the marks, the degree of resemblance phonetically and visually, the nature of the goods, the class of purchasers, and the mode of purchase all feed into the analysis. For pharmaceutical marks the Court demanded an even stricter standard, because confusion there can be dangerous, not just commercially annoying.

But similarity of marks alone doesn’t decide it. The goods or services matter just as much. In M/s. Nandhini Deluxe v. M/s. Karnataka Co-operative Milk Producers Federation Ltd., (2018) 9 SCC 183, the Supreme Court allowed a later mark to coexist with an earlier one within the same broad class, because the actual goods were different and there was no real likelihood of confusion. The lesson for opponents: don’t assume that sharing a class number wins your case. You have to show overlap in the goods or services the consumer actually encounters.

Section 18 (proprietorship defects) and bad-faith opposition

Section 18 of the Trade Marks Act, 1999 governs who may apply: only a person “claiming to be the proprietor” of the mark. That opens a distinct line of opposition. If the applicant isn’t the true proprietor (say, a distributor trying to register a foreign principal’s mark in their own name, or an applicant filing in bad faith to block a competitor) the opposition can attack the application at its root.

Bad-faith filings are a real and growing problem, and Section 18 read with Section 11(10) gives opponents a route to challenge them. The expert point worth flagging: proprietorship and bad-faith grounds are evidence-heavy. You’ll need documents showing the prior relationship, the chain of title, or the applicant’s knowledge of your rights. Plead it, but be ready to prove it at the Rule 45 stage.

Section 9 (absolute) vs Section 11 (relative): which ground do you cite?

So which one do you actually run? The honest answer is often both, but for different reasons. If your complaint is about the mark itself (it’s descriptive, generic, or deceptive), that’s Section 9. If your complaint is that it clashes with your earlier mark, that’s Section 11. A prior user almost always leads with Section 11, because their grievance is the conflict with their own rights. A consumer or trade objector challenging, say, a misleading geographical claim leads with Section 9.

In practice, experienced agents plead the strongest ground first and add the others as alternatives, each as its own clearly numbered paragraph in the notice of opposition. What you should never do is throw every section at the wall hoping one sticks. A focused notice that cites the right ground with the right facts is far more persuasive than a scattergun one. The Registrar, and later the High Court on appeal, reward precision.

The trademark opposition timeline in India (stage-by-stage table)

How long does this actually take, and where exactly are the deadlines? This is the question every brand owner asks first and the one most pages answer worst. The trademark opposition timeline isn’t a single duration; it’s a chain of statutory windows, each with its own clock and its own penalty for missing it. Lay them out in one place and the whole process stops feeling like a black box.

[INFOGRAPHIC: infographic-01]

Here is the consolidated end-to-end timeline, stage by stage, with the authority, the deadline, whether it can be extended, and what happens if you miss it.

How long does a trademark opposition take end to end?

Realistically, budget 18 to 36 months from the day you file the notice of opposition to a final decision. The faster end (around a year and a half) happens when both sides hit their deadlines cleanly and the Registry’s hearing calendar is moving. The slower end stretches past three years when evidence stages drag, adjournments pile up, or the relevant Trade Marks Registry is congested.

It helps to see how the opposition clock overlaps with the registration clock. The application’s own journey (filing, examination, advertisement) happens before opposition even becomes possible. Opposition then sits as a parallel track that pauses registration until it’s resolved. The International Trademark Association has noted that the Indian Trade Marks Office is making measurable progress on opposition pendency, so the trend is cautiously toward the faster end of that range.

Why oppositions stretch to two or three years

So why do so many oppositions take the long road? Three reasons recur. First, the evidence stages: each Rule 45/46/47 affidavit round carries its own one-to-two-month window, and parties routinely use the full time. Second, service and notification delays at the Registry, which push back when the next clock even starts. Third, the hearing backlog, where getting a date can take many months on its own.

Here’s the second-order effect most people miss. Because the deadlines themselves are non-extendible but the gaps between stages are unpredictable, the backlog actually raises the premium on procedural discipline. The parties who suffer least from the delay are the ones who file early in each window and keep an immaculate proof-of-service record, so they’re never the cause of the next bottleneck. The slow system punishes the disorganised far more than the organised.

Form TM-O fees and the e-filing process (2026)

Before you file anything, you need to know what it costs, and this is one area where the public guidance is genuinely contradictory. Some sources quote one figure, some another, and almost none state both the e-filing and the physical-filing fee cleanly. So here are the numbers from the Trade Marks Rules, 2017 First Schedule as they stand in 2026.

Is the opposition fee per class or per application?

This catches people out. The Form TM-O fee is charged per class opposed, not once per opposition. The First Schedule to the Trade Marks Rules, 2017 puts it plainly: the fee is “for each class opposed or counterstatement filed.” So if a single advertised application covers three classes and you want to oppose all three, you multiply the per-class fee accordingly: a three-class opposition costs ₹8,100 at the e-filing rate.

The practical implication is straightforward but easy to underestimate. A multi-class opposition isn’t three times more complex, but it is roughly three times more expensive on the government fee alone. Work out the class count before you budget, because the headline “₹2,700” figure is only the per-class base.

Is e-filing with a DSC mandatory in 2026?

For practical purposes, yes. E-filing through the official IP India portal at ipindiaonline.gov.in is the standard channel in 2026, and filing electronically requires a valid Digital Signature Certificate (DSC) for the person signing. The portal walks you through selecting Form TM-O, entering the impugned application number, uploading the grounds, and paying the fee online.

How do you actually file the opposition online? You log in to the portal with your IP India credentials, select the e-filing of Form TM-O against the advertised application, fill in the opponent details and the grounds, attach the notice, sign with the DSC, and pay. You get an electronic acknowledgement with a reference number, which is your proof of filing date. (Fair warning: keep that acknowledgement. The date on it is what fixes whether you filed inside the four-month window.)

Is the opposition fee refundable, and what’s the real end-to-end cost?

The government filing fee for Form TM-O is generally not refundable once the opposition is filed, even if you later withdraw or settle. Treat it as a sunk cost the moment you submit.

Do you need a lawyer or agent to file? Legally, no. An individual can file their own opposition. But the practical reality is that most oppositions are run through a registered trademark agent or IP lawyer, because the drafting (the grounds, the Rule 45 affidavit, the hearing submissions) is where cases are won and lost. So what’s the real end-to-end cost? The government fee is the small part. Professional fees for drafting the notice, the evidence affidavits, and arguing the hearing typically dwarf the official fee, and they scale with how hard the matter is fought. Budget for the professional work, not just the ₹2,700, because that’s where the actual money goes.

Step-by-step trademark opposition procedure (Form TM-O)

This is the spine of the whole process, so let’s make it concrete. The trademark opposition procedure runs as a sequence of discrete steps, each on its own clock. Skip the prose-summary approach you’ll see elsewhere; what you need is each stage as a separate step with its deadline and its consequence, because that’s how practitioners actually docket the matter. Here’s the seven-step sequence at a glance, then each step in detail.

1. Watch the Trade Marks Journal and confirm the advertisement.
2. File the notice of opposition on Form TM-O within four months.
3. Applicant files the counter-statement on Form TM-O within two months.
4. Opponent files evidence in support of opposition (Rule 45) within two months.
5. Applicant files evidence in support of application (Rule 46) within two months.
6. Opponent files evidence in reply (Rule 47) within one month (optional).
7. Hearing, then the Registrar’s decision.

[INFOGRAPHIC: infographic-02]

For readers who want to do this professionally rather than once, it’s worth understanding that each of these steps is a billable, skilled task. That’s part of why the path to becoming a trademark attorney in India is built around procedural fluency, not just substantive law.

Step 1: Watch the Trade Marks Journal and confirm advertisement

You can’t oppose a mark you don’t know about, which makes journal-watching the real first step. The Trade Marks Journal is published weekly on the IP India site, and every accepted application appears there before registration. Section 20 of the Trade Marks Act, 1999 provides for advertisement of an accepted application in the Journal, and the four-month opposition clock then runs from the date of that advertisement. The notice of opposition itself is filed under Section 21(1) read with Rule 42 of the Trade Marks Rules, 2017, which sets the four-month Form TM-O window.

How do you check whether a mark was published? You search the journal and the public trademark search on the IP India portal by mark, by applicant, or by class. Many brand owners set up a standing watch so conflicting marks surface automatically, rather than relying on someone happening to notice. You can also use WIPO tools to monitor your IP across jurisdictions if your brand operates internationally. One pitfall worth flagging: you generally cannot oppose a mark before it’s advertised, because there’s nothing public to oppose yet. The opposition window opens at advertisement, not at filing.

Step 2: File the notice of opposition on Form TM-O (four-month window)

Once a conflicting mark is advertised, the clock starts. Under Section 21(1) of the Trade Marks Act, 1999, you have four months from the date of advertisement to file the notice of opposition on Form TM-O. This window is non-extendible. One day late and the opposition is time-barred, and the mark proceeds toward registration.

The notice itself sets out the grounds (Section 9, Section 11, Section 18, or others), identifies the opposed application, and states the opponent’s interest. Precision here pays off later, because the grounds you plead frame the entire dispute. So how do you avoid the most common failure? Diary the four-month date the moment you spot the advertisement, and file with a week or two to spare. Filing on the last afternoon is how good cases die to portal glitches.

Step 3: Counter-statement on Form TM-O (Rule 44, two months)

The Registry serves the notice of opposition on the applicant. Now the burden shifts. Under Rule 44 of the Trade Marks Rules, 2017, read with Section 21(2), the applicant must file a counter-statement on Form TM-O within two months of receiving the notice. The counter-statement answers the grounds and sets out the applicant’s defence.

This deadline is non-extendible, and the consequence is severe: if the applicant doesn’t file the counter-statement in time, the application is deemed abandoned. Note that both the notice of opposition and the counter-statement use the same Form TM-O; they’re different filings on the same form, which is exactly why people confuse them. A common question is whether the counter-statement deadline can be pushed. It can’t, and we’ll return to why in the deemed-abandonment section.

Step 4: Evidence in support of opposition (Rule 45 affidavit, two months)

Once the counter-statement is served on the opponent, the evidence stages begin. Under Rule 45 of the Trade Marks Rules, 2017, the opponent has two months from service of the counter-statement to file evidence in support of the opposition, by way of affidavit. This is where the opponent proves the facts behind the grounds: prior use, reputation, the chain of title, the likelihood of confusion.

This is the stage that sank the case in the Sun Pharma ruling. The opponent filed its Rule 45 evidence a few days late and asked the Registrar to extend the window. The Delhi High Court held the Registrar has no power to do so: the two-month period is mandatory. Miss it, and the opposition is deemed abandoned. So the rule for opponents is simple and unforgiving: the Rule 45 affidavit is as time-critical as the opposition itself.

Step 5: Evidence in support of application (Rule 46 affidavit, two months)

Now it’s the applicant’s turn to prove its side. Under Rule 46 of the Trade Marks Rules, 2017, the applicant has two months from receiving the opponent’s Rule 45 evidence to file its own evidence in support of the application, again by affidavit. This is where the applicant builds its defence: its own use, its distinctiveness, the absence of confusion.

Rule 46 carries a useful option. The applicant may, instead of filing fresh evidence, give written intimation that it will rely on the facts already stated in the counter-statement. That waiver has to be intimated within the same window, in writing. But if the applicant neither files evidence nor gives that intimation in time, the application can be treated as abandoned. The waiver is a legitimate tactical choice; silence is not.

Step 6: Evidence in reply (Rule 47 affidavit, one month, optional)

The opponent gets the last word on evidence. Under Rule 47 of the Trade Marks Rules, 2017, the opponent may file evidence in reply within one month of receiving the applicant’s Rule 46 evidence. This stage is optional and confined to rebutting what the applicant raised; it isn’t a chance to open new grounds.

Because it’s optional, many opponents skip it where the applicant’s evidence didn’t introduce anything that needs answering. But where the applicant’s affidavit makes a factual claim that the opponent can decisively rebut (a forged date, a misstated chain of use) the Rule 47 reply is worth filing. Use it surgically, within the one month, or not at all.

Step 7: Can you waive or reserve evidence?

Here’s a part most guides omit entirely. At the Rule 45 and Rule 46 stages, a party that doesn’t wish to file fresh evidence can instead give written intimation that it will rely on the facts already stated in its notice of opposition or counter-statement. This is the “reserve” or waiver option, and it has to be exercised inside the same prescribed window.

Why would you reserve evidence? Sometimes the notice or counter-statement already contains everything you need, and a fresh affidavit adds nothing. Reserving it saves time and cost while keeping you compliant. The expert caution: reserving evidence is a deliberate written act, not a default. If you simply do nothing because you “had no more evidence,” you risk the deemed-abandonment consequence. The written intimation is what protects you. After the evidence stages close (whether through affidavits or reservation), the matter proceeds to a hearing.

Deemed abandonment: the deadline traps that decide oppositions

If there’s one concept that separates practitioners who win oppositions from those who lose them, it’s “deemed abandonment.” It’s the mechanism by which a missed deadline doesn’t just delay your case; it ends it, automatically, without a hearing on the merits. Understanding exactly when it bites is the difference between a live opposition and a dead one.

Deemed-abandonment callout. Two traps decide a large share of oppositions. First: if the applicant misses the two-month counter-statement deadline (Rule 44, read with Section 21(2)), the application is deemed abandoned. Second: if the opponent fails to act within the Rule 45 evidence window, the opposition is deemed abandoned. Both deadlines are non-extendible. There is no discretionary save.

What does “deemed abandoned” mean for the application?

When the law says an application is “deemed abandoned,” it means the application is treated as given up by operation of law, not because the applicant chose to abandon it. The applicant misses the counter-statement deadline, and the application falls away as if it had been withdrawn. There’s no separate order finding fault; the abandonment is automatic.

The practical sting is that the applicant often doesn’t realise it has happened until much later. A mark that was on its way to registration simply stops, because a two-month window passed unobserved. So the pitfall, for applicants, is treating the notice of opposition as something to “get around to.” It isn’t. The clock starts the moment the notice is served, and the penalty for inattention is the loss of the application itself.

Can the counter-statement or Rule 45 deadline be extended?

This is the question everyone asks once they realise the stakes, and the answer is the hard part. No. The counter-statement deadline under Rule 44 and the evidence deadline under Rule 45 are non-extendible.

The authority on the evidence side is the Sun Pharma ruling, where the Delhi High Court held squarely that the Registrar has no power to extend the Rule 45 evidence-filing period. A strong opponent lost because it filed a few days late and there was no statutory discretion to rescue it. So can a documented illness, a portal outage, or a genuine oversight reopen the window? On the deadline itself, no. The discipline the law demands is to never need the extension, because the extension doesn’t exist.

The notice or counter-statement was never served: what now?

There’s one narrow but important escape, and it’s where the 2025 case law matters. What happens if the counter-statement or the notice was never actually served on you because of a technical glitch, and the Registry then treats the matter as abandoned? That’s not a missed deadline on your part; it’s a failure of service.

The Delhi High Court has held, in the service-glitch line of cases including Jyothy Labs Ltd. v. Registrar of Trade Marks (Delhi HC, 2025), that an opposition cannot be deemed abandoned where the counter-statement was never genuinely served on the opponent due to a technical failure. Substantive justice prevails over a technical lapse that wasn’t the party’s fault. The second-order lesson is sharp: because the deadlines themselves are unforgiving, proof-of-service discipline has become a core competency. You preserve the record (portal timestamps, served-copy acknowledgements, email trails) so that if a glitch ever costs you a stage, you can show the document never reached you. The non-extendible deadlines and the heightened IPD scrutiny together raise the premium on procedural drafting and proof-of-service hygiene more than any substantive skill.

Hearing and the three outcomes of an opposition

Once the evidence stages close, the opposition moves to its decisive phase: the hearing. This is where both sides argue the matter before the Registrar, and where the case is finally won, lost, or split. After two years of filings, the hearing is often short, but it’s the stage that produces the order.

How the hearing is fixed and held

The Registrar fixes the hearing and notifies both parties. Under Rule 50 of the Trade Marks Rules, 2017, the parties are entitled to at least one month’s notice of the hearing date, and a party cannot seek more than two adjournments, each for no more than thirty days. Hearings are increasingly conducted through the Registry’s video-hearing facility, with parties or their agents appearing remotely.

Where is the hearing held, and how is it scheduled? It’s listed before the relevant Trade Marks Registry that handles the application, on a date the Registrar fixes after evidence closes. So the practical point for agents is to keep the adjournment requests minimal and well-reasoned, because the Registrar’s patience (and the rules) won’t tolerate a party stringing out the hearing indefinitely.

The three outcomes, and the cost of non-appearance

After hearing both sides, the Registrar can do one of three things. The opposition can be dismissed and the mark registered; the opposition can be allowed and the mark refused; or the mark can be allowed in part (for some goods or classes but not others), a partial outcome that’s more common than people expect where the goods overlap unevenly.

What happens if you don’t show up at the hearing? It’s a real risk, not a technicality. Non-appearance can be treated as abandonment of your opposition (if you’re the opponent) or can lead to the matter being decided ex parte against you. So after carrying a case through four months of opposition and two years of evidence, skipping the hearing can hand the other side the win by default. Mark the hearing date with the same seriousness as the filing deadlines, and arrange representation well in advance.

What changed in trademark opposition law: 2024 to 2026

If your reference point for opposition practice is a guide written before 2024, parts of it are now wrong. The last two years reshaped both the rules of the game and where you go when you lose. Here’s what changed, and why it matters for any opposition filed in 2026.

What changed, 2024 to 2026. Four developments stand out. The Delhi High Court in the Sun Pharma ruling (2024) confirmed that the Rule 45 evidence window is non-extendible. The 2025 service-glitch jurisprudence, including the Jyothy Labs ruling, protected oppositions from technical-abandonment where documents were never genuinely served. The Delhi High Court has stayed mass and automatic abandonment of applications on purely technical grounds. And, on the access side, the IPAB is gone: appeals now go to the High Court Intellectual Property Divisions, with mandatory e-filing and DSC the standard channel.

From the IPAB to the High Court IPD: how the appeal route changed

For years, appeals from the Registrar’s opposition decisions went to the Intellectual Property Appellate Board (IPAB), originally constituted under Section 83 of the Trade Marks Act, 1999. That’s no longer the route, and the change has real consequences for where and how you appeal.

The shift was years in the making. The Trade Marks Rules, 2017 consolidated multiple legacy opposition forms into the single Form TM-O and tightened the evidence timelines. In 2018, the Supreme Court decided Nandhini Deluxe, refining the goods-overlap analysis. In 2021, the IPAB was abolished. In 2022, the Delhi High Court notified its dedicated IP Division rules, operationalising specialised IP benches. Each step moved opposition practice toward faster, more specialised adjudication, and away from the older tribunal model.

Where do you appeal an adverse opposition decision now?

So if the Registrar decides against you, where do you go? To the High Court, through its Intellectual Property Division. The IPAB was abolished by the Tribunals Reforms Act, 2021 (effective August 2021), and its appellate jurisdiction over trademark matters passed to the High Courts. The Delhi High Court’s IPD operates under the Delhi High Court Intellectual Property Division Rules, 2022, and other High Courts (Madras and Calcutta among them) have followed with their own IP benches.

What does opposing before the Registrar versus litigating in the High Court actually look like as a path? The opposition itself stays before the Registrar; the High Court IPD is the appellate forum once the Registrar has decided. So you don’t choose between them at the start. You run the opposition before the Registry, and the IPD is where you go if the outcome is wrong and worth challenging. For brands also pursuing international filings under the Madrid Protocol, the domestic opposition outcome can shape the cross-border strategy too.

Future outlook: where opposition practice is heading

What should practitioners expect over the next two to five years? Early signals suggest continued consolidation of the High Court IPD model across more states, which is likely to make opposition appeals more predictable and faster than the old IPAB backlog ever was. As the specialised benches bed in, the variance in how appeals are handled should narrow.

On timelines, the trend is cautiously positive. With the Registry making progress on opposition pendency and the IPD reducing appellate delay, practitioners expect end-to-end durations to drift toward the lower (roughly 18-month) end of the current range rather than the three-year tail. And on the front end, AI-assisted journal monitoring is likely to push oppositions earlier and make them more professional, because conflicting marks get flagged the week they’re advertised rather than months later. The net effect: more, better-prepared oppositions, decided faster.

Opposition vs rectification: the four-month timing trap

Here’s the trap that costs brand owners the most money, and it’s purely about timing. Opposition is a pre-registration remedy with a four-month window. Miss that window, and the mark registers, and your only route left is rectification under Section 57, which is slower and costlier. The choice between opposition and rectification often isn’t a choice at all; it’s decided by which side of the four-month line you’re on.

So what’s the difference, factor by factor? Opposition happens before registration, on Form TM-O, before the Registry, within four months of advertisement, and it’s the cheaper, faster route. Rectification or cancellation under Section 57 of the Trade Marks Act, 1999 happens after registration, can be filed at any time, and is generally costlier and slower because you’re now dismantling a granted right rather than blocking a pending one.

Opposition vs rectification: which applies and when?

The decision tree is short. If the conflicting mark is still an application (advertised but not yet registered) and you’re inside four months of advertisement, oppose. If it has already registered, or the four months have run, your route is rectification or cancellation under Section 57.

What if you missed the four-month window? You’re not entirely without remedy, but your options narrowed sharply. Once the mark registers, you file for rectification under Section 57, which is a separate, more involved proceeding. How does Section 57 cancellation differ from opposition in substance? Opposition stops a right from being granted; cancellation under Section 57 takes away a right already granted, which is a higher bar and a heavier process. The practical message: the four-month opposition window is the cheap door. Once it closes, every remaining route costs more.

Can a registered trademark still be challenged after registration?

Yes. Registration isn’t the end of the story. A registered mark can be challenged through rectification or cancellation under Section 57 on grounds such as the mark being wrongly registered, registered without sufficient cause, or remaining wrongly on the register. There’s also the renewal dimension: a mark that isn’t renewed under Section 25 of the Trade Marks Act, 1999 can lapse, which is a different way a registration ends.

If the dispute has already moved past the register and into actual market use, the remedy can shift again, to court. Where a registered mark is being infringed, the owner can escalate to a trademark infringement suit rather than stay within the Registry’s rectification process. So the lifecycle is layered: oppose before registration, rectify after registration, and litigate infringement where the conflict is playing out in the marketplace.

Settlement, coexistence and withdrawal of an opposition

Not every opposition has to be fought to a decision, and the smart ones often aren’t. A large share of oppositions settle, because both sides eventually do the maths: years of evidence and a hearing, possibly followed by a High Court appeal, against a negotiated arrangement that lets both businesses get on with trading. Knowing the settlement routes is as much a part of opposition strategy as knowing the grounds.

Can parties settle an opposition midway?

They can, at almost any stage. If the opponent and applicant reach terms (a limitation on goods, a change to the mark, a coexistence arrangement) they can give effect to it through the Registry. The IP India portal provides an Opposition Settlement Request route, through which parties record a settlement and have the opposition disposed of accordingly. The opposition can also simply be withdrawn by the opponent.

The practical reality is that settlement gets more attractive the longer a matter runs, because the cost and uncertainty climb with every stage. An opposition settled before the evidence rounds saves both sides the most. One caution: the government filing fee already paid generally isn’t refunded on settlement, so the saving is in the avoided future cost, not in recovering what’s been spent.

Coexistence agreement vs fighting it out: which is cheaper?

A coexistence agreement is a contract in which both parties agree to use their respective marks under defined conditions (different goods, different territories, different presentation) so they don’t conflict. Compared with fighting an opposition to a decision and possibly appealing to the High Court IPD, a coexistence agreement is almost always cheaper and faster.

So when does it make sense? When both marks can genuinely coexist without confusing consumers, and when the cost of winning outright (years of proceedings plus a possible appeal) exceeds the commercial value of excluding the other party entirely. The mistake we see is treating coexistence as “giving up.” Often it’s the rational outcome: you secure your space, the other side secures theirs, and neither burns a small fortune proving a point. The earlier you reach it, the more you save.

Landmark trademark opposition cases every practitioner should know

Opposition practice is shaped as much by case law as by the rules, and four rulings in particular tell you how the system actually behaves. They cover the two things that decide oppositions: the substantive test for confusion, and the procedural discipline that the deadlines demand. Know these, and you understand both why oppositions are won and how they’re lost.

Sun Pharma Laboratories Ltd. v. Dabur India Ltd. (Delhi HC, 2024)

The most consequential recent ruling on opposition procedure is Sun Pharma Laboratories Ltd. v. Dabur India Ltd., C.A.(COMM.IPD-TM) 146/2022 (Delhi HC, 2024). The Delhi High Court’s IP Division held that the Registrar has no power to extend the Rule 45 evidence-filing period. The two-month window is mandatory and non-extendible, full stop. A late evidence affidavit, however strong the underlying case, means the opposition is deemed abandoned. This is the case that turned “diary your deadlines” from good advice into hard law.

Nandhini Deluxe v. KMPF (SC, 2018)

On the substantive side, Nandhini Deluxe v. Karnataka Co-operative Milk Producers Federation Ltd., (2018) 9 SCC 183 is essential. The Supreme Court held that similar or even deceptively similar marks can coexist where the actual goods are different, refusing to let one proprietor monopolise an entire class heading. The takeaway for opponents is that sharing a class number isn’t enough; you have to show real overlap in the goods or services consumers encounter. Otherwise, coexistence is exactly what the law contemplates.

Cadila Healthcare Ltd. v. Cadila Pharmaceuticals Ltd. (SC, 2001)

The foundational test for deceptive similarity comes from Cadila Health Care Ltd. v. Cadila Pharmaceuticals Ltd., (2001) 5 SCC 73. The Supreme Court laid out the multi-factor approach (the nature and resemblance of the marks, the nature of the goods, the class of purchasers, the mode of purchase) and applied heightened scrutiny to pharmaceutical marks, where confusion can be dangerous. Almost every Section 11 opposition argument traces back to the Cadila factors, which makes it the case opponents and applicants both build on.

Jyothy Labs / the 2025 service-glitch line (Delhi HC)

The newest strand is the 2025 service-glitch jurisprudence, anchored by Jyothy Labs Ltd. v. Registrar of Trade Marks (Delhi HC, 2025). The Delhi High Court held that an opposition can’t be deemed abandoned where the counter-statement was never actually served because of a technical glitch. Substantive justice prevails over a technical lapse that wasn’t the party’s fault. Read alongside Sun Pharma, it draws the line cleanly: deadlines are strict, but you can’t be penalised for a failure that was the system’s, not yours, provided you can prove it.

Sample Form TM-O notice of opposition (annotated draft)

Most guides describe the notice of opposition. Almost none show you one. Here’s an annotated skeleton you can model your own draft on, using generic placeholders and a clearly fictional brand so nothing here is a real party. Treat the bracketed parts as fields to fill in, and the notes as the reasoning behind each block.

IN THE OFFICE OF THE REGISTRAR OF TRADE MARKS, [Registry location]

NOTICE OF OPPOSITION (FORM TM-O) under Section 21 of the Trade Marks Act, 1999 read with Rule 42 (filing of the notice) and Rule 43 (particulars of the notice) of the Trade Marks Rules, 2017

In the matter of Application No. [application number] for the mark “[opposed mark, e.g. GLOWHAVEN]” in Class [class number], advertised in Trade Marks Journal No. [journal number] dated [date].

Opponent: [Opponent name / “the prior user”], proprietor of the mark “[earlier mark, e.g. GLOWHAVEN]”, [address].

Applicant: [Applicant name], [address].

The Opponent gives notice of opposition to the registration of the above application on the following grounds:

1. (Relative grounds, Section 11): The opposed mark is identical with / deceptively similar to the Opponent’s earlier mark “[earlier mark]”, used since [year] in respect of [goods/services], such that there exists a likelihood of confusion among the public.

2. (Absolute grounds, Section 9): The opposed mark is devoid of distinctive character / is descriptive of [characteristic] and is therefore not registrable.

3. (Proprietorship, Section 18): The Applicant is not the true proprietor of the mark within the meaning of Section 18, [state basis].

4. (Prior use / passing off): The Opponent is the prior adopter and user of the mark and registration of the opposed mark would amount to passing off.

The Opponent prays that the application be refused with costs.

A few annotations on what follows the notice. After the counter-statement, the Rule 45 affidavit is where the opponent proves paragraph by paragraph what the notice asserts: an affidavit of use exhibiting dated invoices, advertisements, and sales figures to establish prior use and reputation. The Rule 46 affidavit is the applicant’s equivalent. Keep each factual claim in the notice tied to a document you can later exhibit, because the hearing turns on proof, not assertion. The cleaner the notice, the cleaner the evidence stage that has to back it up.

Frequently asked questions

1. What is the time limit for filing a trademark opposition in India? You have four months from the date the mark is advertised in the Trade Marks Journal to file a notice of opposition on Form TM-O. This window is set by Section 21(1) of the Trade Marks Act, 1999 and is non-extendible. Miss it by even a day and the opposition is time-barred, leaving only the costlier rectification route after registration.

2. What is the government fee for Form TM-O in 2026? The government fee for filing Form TM-O is ₹2,700 per class for e-filing through the IP India portal, and ₹3,000 per class for physical filing. These figures come from the Trade Marks Rules, 2017 First Schedule, which charges the fee “for each class opposed.” Multi-class oppositions therefore cost proportionally more (a three-class e-filing is ₹8,100).

3. Is the opposition fee per class or per application? It’s charged per class opposed, not once per opposition. The First Schedule to the Trade Marks Rules, 2017 states the fee is “for each class opposed.” If an application covers three classes and you oppose all three, you pay the per-class fee three times over (₹8,100 at the e-filing rate). The headline ₹2,700 figure is the single-class base, so calculate your class count before budgeting.

4. Who can file a trademark opposition in India? Any person may file. Section 21(1) uses the words “any person,” not “any registered proprietor,” so you don’t need to own a registered mark or even be in the same trade. The breadth is deliberate, because opposition surfaces objections in the public interest. The opposition must still rest on a recognised statutory ground.

5. Can you oppose a trademark without owning a registered trademark? Yes. A prior user with no registration, a foreign business with a reputation in India, or a consumer-interest objector can all oppose. The “any person” standard makes registration unnecessary for standing. That said, the strongest oppositions come from parties with concrete rights to point to, such as prior use, an earlier application, or demonstrable goodwill.

6. How long do you get to file the counter-statement? The applicant has two months from receiving the notice of opposition to file a counter-statement on Form TM-O, under Rule 44 read with Section 21(2). This deadline is non-extendible. If the applicant misses it, the application is deemed abandoned, which means the mark falls away automatically without any decision on the merits.

7. How long does a trademark opposition take to resolve in India? Budget roughly 18 to 36 months, or one to three years, from filing the notice to a final decision. The faster end happens when both sides meet their deadlines and the Registry’s hearing calendar is moving. Evidence delays, adjournments, and Registry backlog push matters toward the slower end.

8. Where do you appeal an adverse opposition decision now (post-IPAB)? To the High Court, through its Intellectual Property Division. The IPAB was abolished by the Tribunals Reforms Act, 2021, and its trademark jurisdiction passed to the High Courts. The Delhi High Court IPD operates under the IP Division Rules, 2022, with Madras and Calcutta among the courts that have followed.

9. What happens if the applicant does not file a counter-statement in time? The application is deemed abandoned under Section 21(2). The two-month counter-statement window is non-extendible, so a missed deadline ends the application automatically. There’s no separate finding of fault; the abandonment happens by operation of law, and applicants often don’t notice until much later.

10. Can the Rule 45 evidence-filing deadline be extended by the Registrar? No. In Sun Pharma Laboratories Ltd. v. Dabur India Ltd. (2024), the Delhi High Court held that the Registrar has no power to extend the two-month Rule 45 evidence window. A late affidavit means the opposition is deemed abandoned, regardless of the strength of the underlying case. The discipline is to never need an extension.

11. I missed the four-month opposition window. What are my options? Once the four months pass, you can no longer oppose, and if the mark registers, your route is rectification or cancellation under Section 57. That’s a separate, slower, costlier proceeding because you’re dismantling a granted right rather than blocking a pending one. Where infringement is occurring, a court suit may also be available.

12. How much does an opposition really cost end-to-end (govt + attorney)? The government fee (₹2,700 e-filing or ₹3,000 physical, per class opposed) is the small part. The bulk of the cost is professional fees for drafting the notice, the evidence affidavits, and arguing the hearing, which scale with how hard the matter is fought. Budget for the professional work, because that’s where most of the spend goes.

13. Can parties settle an opposition matter midway? Yes, at almost any stage. The parties can record a settlement (a coexistence arrangement, a limitation of goods, a withdrawal) through the IP India portal’s Opposition Settlement Request route. Settlement gets more attractive the longer a matter runs, because the cost and uncertainty climb with each stage. The filing fee already paid generally isn’t refunded.

14. Trademark objection vs trademark opposition: what is the difference? An objection is raised by the Trade Marks examiner during examination, before the mark is advertised, and you answer it with a reply to the examination report. An opposition is raised by a third party after advertisement, on Form TM-O. One is the Registry’s internal scrutiny; the other is an outsider’s challenge.

15. Opposition vs rectification: which applies and when? Opposition applies before registration, within four months of advertisement, on Form TM-O. Rectification or cancellation under Section 57 applies after the mark has registered and can be filed at any time. Opposition is the cheaper, faster door; once the four-month window closes, rectification is the slower, costlier route that remains.

16. E-filing vs physical filing of Form TM-O: fee and practicality? E-filing through ipindiaonline.gov.in costs ₹2,700 per class and requires a valid Digital Signature Certificate; physical filing costs ₹3,000 per class. E-filing is the standard channel in 2026, generates an instant dated acknowledgement (your proof of the filing date), and is both cheaper and more practical than physical filing.
