How Trademark Opposition Works in the UK

What is trademark opposition?

Trademark opposition is a formal procedure that allows any person to challenge a trademark application before it is registered. In the UK, once the IPO examiner accepts an application, it is published in the Trade Marks Journal. From the date of publication, there is a 2-month window during which anyone can file a notice of opposition.

Opposition is not a court action. It is an administrative proceeding heard by a hearing officer at the UK IPO. The process is paper-based (or, more accurately, conducted through the IPO's online tribunal system) and is significantly cheaper and faster than High Court litigation, though it can still be substantial in cost and duration.

In 2024, the UK IPO received 6,695 oppositions. That figure has been climbing steadily; it reflects the growing volume of trademark applications and the increased awareness among brand owners of the need to police their marks actively.

Who can oppose a trademark?

Under the Trade Marks Act 1994, any person may file a notice of opposition. You do not need to be a trademark owner. You could be:

• The owner of an earlier registered trademark that conflicts with the application
• A business with unregistered rights (e.g. goodwill in a trading name acquired through use)
• A competitor who believes the mark is descriptive or generic and should not be registered
• Any member of the public with a legitimate concern (for instance, that a mark is deceptive or contrary to public policy)

That said, the overwhelming majority of oppositions are filed by owners of earlier trademarks who believe the new application is too similar to their existing mark.

Grounds for opposition

Opposition grounds fall into two broad categories under the Trade Marks Act 1994.

Absolute grounds (section 3)

These relate to the inherent registrability of the mark itself. A mark may be opposed on the basis that it:

• Is devoid of distinctive character (s.3(1)(b)) – for example, a single common word that describes the goods
• Consists exclusively of signs that describe the goods or services (s.3(1)(c))
• Has become customary in the relevant trade (s.3(1)(d))
• Is contrary to public policy or morality (s.3(3))
• Is deceptive as to the nature, quality, or geographical origin of the goods/services (s.3(3)(b))
• Is a specially protected emblem (s.3(5))
• Was filed in bad faith (s.3(6))

Relative grounds (section 5)

These relate to conflicts with earlier rights. A mark may be opposed because:

• It is identical to an earlier mark and the goods/services are identical (s.5(1))
• It is identical or similar to an earlier mark and the goods/services are identical or similar, creating a likelihood of confusion (s.5(2))
• It is identical or similar to an earlier mark with a reputation in the UK, and use without due cause would take unfair advantage of, or be detrimental to, the earlier mark's distinctive character or repute (s.5(3))
• Its use would be prevented by the law of passing off or copyright (s.5(4))

The opposition process: step by step

1. Publication in the Trade Marks Journal

Once the IPO examiner is satisfied that an application meets the requirements, it is published in the Trade Marks Journal. This starts the clock on the 2-month opposition period.

2. Filing a notice of threatened opposition (Form TM7a)

If you need more time to decide whether to oppose, you can file a Form TM7a before the 2-month deadline expires. This extends the opposition period by one month and signals to the applicant that opposition is being considered. There is no fee for filing TM7a.

3. Filing a notice of opposition (Form TM7)

To formally oppose, you file Form TM7 with the UK IPO within the opposition period (2 months, or 3 months if TM7a was filed). The form must set out the grounds of opposition and the facts relied upon. There is no official fee for filing TM7.

4. Counterstatement from the applicant (Form TM8)

The applicant has 2 months to file a counterstatement on Form TM8. If they fail to respond, the application is deemed withdrawn. The counterstatement sets out which grounds are denied and why.

5. Cooling-off period

Either party can request a cooling-off period of up to 9 months (extendable to 18 months by agreement). This is specifically designed to allow negotiations. Many oppositions settle during cooling off, through withdrawal of the application, amendment of the specification, or a coexistence agreement.

6. Evidence rounds

If the dispute does not settle, the case moves to evidence rounds:

1. Evidence in chief (opponent): the opponent files evidence supporting their grounds. This typically includes evidence of use and reputation of the earlier mark, examples of the marks side by side, and evidence of the relevant market.
2. Evidence in answer (applicant): the applicant files evidence in response.
3. Evidence in reply (opponent): the opponent may file strictly reply evidence addressing new points raised by the applicant.

Each evidence round has a standard deadline of 2 months, though extensions are routinely granted.

7. Decision

After evidence is complete, the case is decided. This can happen on the papers (without a hearing) or at an oral hearing before a hearing officer. Most cases are decided on the papers. The hearing officer issues a written decision, usually within 2–3 months after the final evidence deadline.

Costs

There is no IPO fee for filing an opposition. However, the real costs come from preparation and legal representation:

• Simple opposition (settles in cooling off): £1,000–£3,000 in attorney fees
• Contested opposition (evidence and decision): £5,000–£15,000+
• Oral hearing: adds £2,000–£5,000

The IPO can award costs to the successful party, but these are based on a published scale and are typically modest: around £1,000–£3,000, rarely covering the full expense of the proceedings.

Success rates and practical advice

Exact success rates vary year to year, but broadly, around 40–50% of oppositions result in the application being refused or withdrawn, while the remainder succeed (the application proceeds). A significant proportion settle before a decision is reached.

Key practical points:

• Search early. The best time to discover a conflicting application is during the publication period, not after registration. Use a trademark monitoring service to watch for new filings.
• Gather evidence early. If you think you may need to oppose, start collecting evidence of your use of the mark, your sales figures, marketing materials, and any instances of actual confusion.
• Consider the specification. Sometimes the real issue is not the mark itself but the breadth of the goods/services specification. A narrowing of the specification through negotiation can resolve the conflict without full opposition.
• Use the cooling-off period. This exists specifically for negotiation. Engage with the other party constructively. A coexistence agreement is often a better outcome for both sides.

When to oppose vs when to negotiate

Not every conflicting application warrants a formal opposition. Consider the following before filing TM7:

A good starting point is to file a Form TM7a (notice of threatened opposition) to extend the deadline, then write to the applicant directly. Many applicants are willing to amend their specification or agree to coexistence terms without the expense of formal proceedings.

Defending against an opposition

If your own trademark application is opposed, do not panic. Many oppositions are speculative or based on weak grounds. Key steps:

1. Read the notice of opposition carefully and identify the specific grounds relied upon.
2. File your counterstatement (Form TM8) within the 2-month deadline. Failure to respond means your application is deemed abandoned.
3. Consider whether a cooling-off period would allow productive negotiation.
4. If the opponent relies on an earlier mark, check whether that mark has been used in the last 5 years. Under section 6A of the Act, you can require proof of use if the earlier mark has been registered for 5 years or more. This is a powerful defence; many earlier marks on the register are not being actively used.

Before filing a trademark application, always run a comprehensive trademark search to identify potential conflicts. Understanding the UK registration process from start to finish will also help you anticipate and prepare for the possibility of opposition.
