To oppose a trademark application in India, you must file a notice of opposition in Form TM-O within four months of the mark being advertised in the Trade Marks Journal. Under Section 21 of the Trade Marks Act, 1999, any person can oppose a trademark without needing to own a registered mark. The opposition can ask the Registrar to refuse registration on grounds such as similarity to an earlier mark or lack of distinctiveness.
Trademark opposition is a key safeguard that lets third parties challenge a mark before it is registered and gains legal protection. You must file it within four months of advertisement or re-advertisement, and this deadline cannot be extended. So, you should monitor the mark and file on time.
This guide explains how to oppose a trademark application, including who can oppose, the grounds, the process, and the fees.
Key Takeaways
- Any person can oppose a trademark by filing Form TM-O within four months of its publication in the Trade Marks Journal under Section 21 of the Trade Marks Act, 1999.
- You must file the notice within the strict four-month deadline, as the authority rejects even a notice filed one day late as time-barred.
- Any person can oppose a trademark, without needing to own a registered mark or have a commercial interest, giving opposition the widest standing in trademark law.
- A trademark can be opposed under Section 9 (absolute grounds) and Section 11 (relative grounds), including lack of distinctiveness, similarity to another mark, or bad faith.
- The online government fee is ₹2,700 per class. The opposition process includes filing a counter-statement, submitting evidence, and attending a hearing before the Registrar.
- You cannot oppose a trademark after registration. Instead, you must challenge a registered trademark through rectification or cancellation under Sections 47 and 57.
What is Trademark Opposition?
A third party can file a trademark opposition as a formal objection after the Trade Marks Journal publishes the trademark but before the Registrar registers it. This process allows third parties to object to a mark they believe should not receive legal protection. This helps keep conflicting or misleading marks off the register.
An opposition sits at a specific stage in the trademark registration process:
- After advertisement: The Registrar opens a trademark for opposition only after examining, accepting, and advertising it in the Trade Marks Journal.
- Before registration: You must file the opposition before the Registrar registers the trademark, as Section 21 of the Trade Marks Act, 1999 provides opposition as a pre-registration remedy.
- Decided at the Registry: The Registrar or a Hearing Officer at the Trade Marks Registry hears the opposition. They decide the case through a defined procedure instead of a court process.
When a third party files an opposition, the Trade Marks Registry changes the application status to “Opposed.” After that, Trademark Registration depends on the outcome of the proceedings.
Who Can Oppose a Trademark Application?
Anyone can oppose a trademark application in India under Section 21 of the Trade Marks Act, 1999. “Any person” means even someone without a registered mark or direct business interest. This wide right exists to keep misleading or conflicting marks off the register.
Here’s who can file an opposition:
- Trademark owner: A registered proprietor or an earlier applicant who believes the new mark is identical or similar to their own.
- Prior users of a mark: Businesses using an unregistered mark before the application, relying on its common law rights.
- Competitors: A rival in the same trade who considers the mark too close to an existing brand in the market.
- Consumers and the public: Any member of the public who believes the mark is deceptive, offensive, or likely to confuse.
- Companies, firms, and associations: Any legal entity, such as a company, partnership firm, trust, or trade association, acting through an authorized person.
Every opponent must file the opposition within four months of the trademark’s advertisement, as the law does not allow any extension of this deadline.
Grounds for Opposing a Trademark
You can oppose a trademark only on valid legal grounds, not just because you dislike the mark. These grounds fall into two categories under the Trade Marks Act, 1999:
Absolute Grounds (Section 9)
This applies when the mark:
- Cannot distinguish the applicant’s goods or services from those of others.
- The mark merely describes the kind, quality, quantity, purpose, or geographical origin of the goods or services.
- The mark consists of words that are common to the trade or customary in everyday language.
- The mark is likely to deceive the public or cause confusion about the nature or origin of the goods.
- The mark contains scandalous or obscene matter, hurts religious sentiments, or violates the Emblems and Names (Prevention of Improper Use) Act, 1950.
Relative Grounds (Section 11)
Relative grounds focus on conflicts with earlier trademarks and how the new mark may affect existing rights:
- Similarity to an earlier mark: The mark is identical or similar to an earlier registered or pending trademark for similar goods or services.
- Likelihood of confusion: The similarity is likely to confuse the public, including an association with the earlier mark.
- Conflict with a well-known mark: The mark takes unfair advantage of, or harms, the reputation of a well-known mark under Section 11(2) of the Trade Marks Act, 1999, even for different goods.
Other Grounds
Apart from similarity and confusion, an opponent can also oppose certain trademark applications based on dishonest or improper intent:
- Bad faith: The applicant files the application dishonestly, such as by copying or blocking a mark that they know is already in use, which constitutes a ground for opposition under Section 11(10)(ii).
- No genuine proprietorship: The applicant is not the rightful owner of the mark, such as a licensee or agent who files it in their own name.
Documents Required to Oppose a Trademark
Filing a notice of opposition requires a set of documents that establish the opponent’s identity, their grounds, and the basis of their claim. The documents required to oppose a trademark are:
- Details of the opposed mark: Include the application number, class, and the journal number and date on which the Trade Marks Journal advertised the mark.
- Opponent’s details: The name, address, and nature of the opponent, whether an individual, company, partnership firm, or other entity.
- Grounds of opposition: The opponent must clearly state the legal grounds for opposition, cite the relevant sections, and explain why the Registrar should not register the mark.
- Details of the earlier mark: The registration or application number and details of any earlier mark relied upon, where the opposition is based on a prior right.
- Proof of prior use: Evidence such as invoices, advertisements, or dated materials, where the opposition is based on prior use of an unregistered mark.
- Power of Attorney (Form TM-M): The opponent provides an authorization that allows a trademark agent or attorney to file and represent them when they engage an agent.
Note: The opponent must state the grounds and supporting details clearly in the notice of opposition, as the Registrar can easily dismiss a vague or incomplete filing. The opponent submits evidence of prior use in full at the evidence stage, but referencing it in the notice strengthens the opposition from the start.
How to Oppose a Trademark Application?
Opposing a trademark application follows a defined process under Section 21 of the Trade Marks Act, 1999, and the Trade Marks Rules, 2017.
Follow these steps to oppose a trademark application in India:
1. Monitor the Trade Marks Journal
- You must watch the weekly Trade Marks Journal to identify a conflicting mark once the Registrar advertises it.
- Note the application number, class, and the date of advertisement, as the four-month deadline runs from this date.
2. File the Notice of Opposition (Form TM-O)
- File the notice of opposition in Form TM-O within four months of the mark’s advertisement, online through the IP India portal (ipindia.gov.in).
- State the grounds of opposition clearly, citing the relevant sections and any earlier marks relied upon.
- Pay the prescribed fee per class, currently ₹2,700 for online filing, after which the system generates an opposition number.
3. Applicant Files the Counter-Statement
- The Registry serves the notice on the applicant, who must file a counter-statement within two months.
- The counter-statement responds to each ground raised in the opposition.
If the applicant fails to file it within two months, the Registrar treats the application as abandoned.
4. Evidence Stage
- The opponent submits evidence by affidavit under Rule 45 within two months of receiving the counter-statement, or gives up the right in writing.
- The applicant then files evidence in support of the application under Rule 46, within two months of receiving the opponent’s evidence.
- The opponent may file evidence in reply under Rule 47, within one month, limited to rebutting the applicant’s evidence.
Note: You must meet each evidence deadline, as missing it can lead the Registrar to treat the opposition or application as abandoned.
5. Hearing Before the Registrar
- Once the evidence is complete, the Registrar schedules a hearing and notifies both parties.
- Each side presents oral arguments, either in person or through an authorized agent.
- If a party does not appear, the Registrar may decide the matter in favor of the other side.
6. Decision and Appeal
- The Registrar issues a reasoned order, either allowing the mark to proceed to registration or refusing it.
- Either party may appeal to the High Court within three months of the order under Section 91 of the Trade Marks Act, 1999. The Court may allow a late appeal if it finds sufficient cause for the delay.
Note: Earlier, parties filed appeals before the Intellectual Property Appellate Board (IPAB), but the government abolished the IPAB in 2021 and transferred its functions to the High Courts. An appeal against the Registrar’s order now goes to the High Court.
Trademark opposition proceedings usually take around 1.5 to 3 years, and they can extend to 5 years or more when parties contest the evidence stages and hearings.
How Much Does It Cost to Oppose a Trademark?
Filing a notice of opposition costs a government fee of ₹2,700 per class for online filing or ₹3,000 per class for physical filing. Here’s how the opposition fees compare:
| Action | Fee (Online, per class) | Physical Filing |
| Notice of opposition (Form TM-O) | ₹2,700 | ₹3,000 |
| Counter-statement (Form TM-O) | ₹2,700 | ₹3,000 |
| Adjournment request (Form TM-M) | ₹900 | ₹1,000 |
Note: The Trade Marks Rules, 2017 prescribe all opposition fees per class and make them non-refundable under the First Schedule. If an opponent files a notice against a multiclass application, they must pay the fee for each class they oppose, so they should calculate the total cost based on the number of classes before filing.
Can You Oppose a Trademark After the Registrar Registers it?
You cannot oppose a trademark after the Registrar registers it. Section 21 of the Trade Marks Act, 1999 allows opposition only against a pending application that the Registrar has advertised but not yet registered. Once the mark is on the register, the four-month opposition window has closed, and a different remedy applies.
An aggrieved person can challenge an already registered mark by filing a rectification or cancellation application. Here’s how the two remedies differ:
- Opposition (before registration): Filed under Section 21 within four months of advertisement by any person to stop a pending mark from being registered.
- Rectification or cancellation (after registration): A person who is affected can file Form TM-O under Sections 47 or 57, before the Registrar or the High Court, to remove or correct a registered trademark.
The main grounds for rectification after trademark registration include:
- Non-use: The mark has not been used for a continuous period of five years and three months from the date of registration, under Section 47.
- Wrongful registration: The mark was registered despite falling foul of the absolute or relative grounds in Sections 9 or 11.
- Fraud or misrepresentation: The registration was obtained through a false declaration or by concealing material facts, under Section 57, for which there is no limitation period.
Note: Opposition and rectification happen at different stages. You must file an opposition within four months when you use rectification to challenge a registered trademark. You can raise non-use claims after five years and three months of continuous non-use, but you can challenge fraud at any time.
Common Mistakes to Avoid When Opposing a Trademark
A few common mistakes can weaken your case or cause your opposition to fail. Avoid these to keep your opposition on track:
- Missing the four-month deadline: The window to file closes four months after the mark’s advertisement and cannot be extended. A notice filed even one day late is rejected as time-barred, so monitor the journal and file early.
- Filing vague grounds: A notice that does not clearly state the grounds or identify the earlier marks relied upon is easily dismissed. Cite the specific sections and set out the facts supporting each ground.
- Missing the evidence deadlines: Each evidence stage under Rules 45 to 47 has a fixed time limit, and missing one can lead to the opposition being treated as abandoned. Track every stage and file within the prescribed time.
- Confusing opposition with rectification: Opposition applies only before registration. Trying to oppose a mark that is already registered fails, as a registered mark must be challenged through rectification instead.
- Assuming appeals go to the IPAB: The Intellectual Property Appellate Board was abolished in 2021, so an appeal against the Registrar’s order now goes to the High Court within three months of the order.
- Not monitoring the journal: Missing the advertisement of a conflicting mark means missing the window entirely. Use a trademark watch to catch conflicting marks in time to oppose them.
