Trademark Opposition — Process, Timeline & How to Defend

Opposition is the stage at which your trademark application stops being a conversation with the Registry and becomes a dispute with another business. Once a mark is advertised in the Trade Marks Journal, a statutory window opens during which any person may oppose its registration. Opposition proceedings are quasi-judicial, run on strict timelines, and are lost far more often on procedural default than on the merits.

Who can oppose, and on what grounds

Any person may file an opposition — the opponent does not need to own a registered trademark, and does not need to show that they are personally affected. In practice oppositions come from proprietors of earlier registered marks, prior users of unregistered marks, and occasionally from competitors acting tactically.

The grounds mirror the examination grounds. On relative grounds, the opponent argues that your mark is identical or deceptively similar to their earlier mark for the same or similar goods, creating a likelihood of confusion, or that it takes unfair advantage of a well-known mark. On absolute grounds, the argument is that the mark is descriptive, generic, non-distinctive, deceptive or contrary to law. An opponent may also plead prior use, bad faith adoption, or passing off.

The procedural sequence

Notice of opposition

The opponent files a notice of opposition in the prescribed form within the statutory window from the date of advertisement, setting out the grounds and the marks relied upon. Extensions of the opposition window are not freely available, so the date of advertisement is the one to diarise.

Counter-statement

You must file a counter-statement within the prescribed period from receipt of the notice. This is the most dangerous deadline in the whole process: failure to file the counter-statement in time results in the application being deemed abandoned, with no discretion to revive it in most cases. Do not wait to assess the strength of the opposition before responding — file, then assess.

Evidence in support of opposition

The opponent then files evidence by way of affidavit, supporting the claims in the notice — registration certificates, invoices, advertising, market presence, evidence of reputation. Alternatively the opponent may waive evidence and rely on the notice.

Evidence in support of application

You respond with your own affidavit evidence: your date and extent of use, invoices, promotional material, turnover attributable to the mark, distribution reach, any registrations you hold in other classes or jurisdictions, and material distinguishing your goods and trade channels from the opponent’s.

Evidence in reply

The opponent may file limited evidence strictly in reply to yours. New grounds cannot be introduced at this stage.

Hearing and decision

The Registrar fixes a hearing at which both sides argue. Non-appearance is treated seriously and generally decides the matter against the absent party. The Registrar then issues a reasoned order allowing the opposition, dismissing it, or allowing registration subject to conditions or limitations on the specification of goods.

How to defend an opposition effectively

• Calendar every deadline the day the notice arrives. Most defences fail on the counter-statement date, not on the argument.
• Check the opponent’s mark is alive. Pull the Registry record. A cited registration that has lapsed, or has not been used for a continuous period, is vulnerable — and a rectification or non-use cancellation action against it can change the balance of the dispute entirely.
• Build the evidence file properly. Affidavit evidence with dated, contemporaneous documents beats assertion. Undated screenshots and unsupported turnover claims carry little weight.
• Compare as a whole. Argue visual, phonetic and conceptual differences on the marks taken in their entirety, as an average consumer with imperfect recollection would encounter them.
• Attack the goods overlap. Even within one class, goods can differ in nature, purpose, trade channel and consumer. Narrowing your specification to remove the overlap is often the cleanest route to registration.
• Consider settlement. A coexistence agreement or letter of consent, sometimes with a limitation on goods or territory, resolves a large share of oppositions faster and more cheaply than fighting to a hearing.

If you are the opponent

The same discipline applies in reverse. Watch the Journal — monitoring is the only way to catch a conflicting application inside the opposition window, and once that window closes your remedy becomes a rectification action after registration, which is slower and harder. Plead your grounds specifically rather than reciting every section, and lead with your strongest evidence of prior use and reputation.

Outcome and appeal

Where the opposition succeeds, the application is refused. Where it fails, the mark proceeds to registration. Either party may appeal the Registrar’s order to the appropriate appellate forum within the prescribed period. A registration that survives opposition is materially stronger in later enforcement, because the objection has already been tested.

Opposition is also a reminder that clearance work at the start is the cheapest stage of the process. A thorough search before filing — covering phonetic and visual similarity, not just identical marks — avoids most oppositions entirely.

Frequently asked questions

What happens if I miss the counter-statement deadline?

The application is deemed abandoned. This is the harshest consequence anywhere in trademark practice and is generally not curable. If you have received a notice of opposition, treat the counter-statement date as immovable.

Can I oppose a mark if mine is not registered?

Yes. Any person may oppose, and prior use of an unregistered mark is a recognised ground. You will need to evidence that use with dated invoices, advertising and market presence — the strength of the evidence is what carries the argument.

How long do opposition proceedings take?

Considerably longer than an uncontested application, because each stage carries its own filing period and a hearing must be scheduled. Plan brand launches on the assumption that an opposed application will not resolve quickly, and consider whether a settlement is commercially preferable.

Can the opposition be settled between the parties?

Yes, and it frequently is. A letter of consent or a coexistence agreement — often with an agreed limitation on the goods, services or territory each side will use — can be filed with the Registry to dispose of the opposition. This is usually the fastest and cheapest resolution where both businesses can genuinely coexist. See also our guide on replying to trademark objections, which covers the earlier examination stage.
