UK Trademark Opposition: Challenging or Defending a Mark Before the UKIPO
When a UK trademark application is published in the Trade Marks Journal, any person can oppose its registration within a 2-month opposition period. Whether you're challenging a conflicting mark or defending your application against opposition, understanding the UKIPO opposition process is essential.
This guide covers the complete UK trademark opposition procedure — from filing to resolution.

The Opposition Period
After the UKIPO examiner approves a trademark application (clearing absolute grounds), the mark is published in the UK Trade Marks Journal.
- Opposition period: 2 months from publication date
- Extension: The period can be extended by 1 month if the potential opponent files a Form TM7A (Notice of Threatened Opposition)
- Total maximum period: 3 months from publication
The TM7A extension is commonly used — it gives the potential opponent time to assess the conflict and attempt to resolve it before initiating formal proceedings.
Grounds for Opposition
Oppositions can be based on relative grounds (Section 5 TMA 1994) and/or absolute grounds (Section 3 TMA 1994).
Relative Grounds (Section 5)
- Section 5(1) — The mark is identical to an earlier mark for identical goods/services
- Section 5(2) — The mark is similar to an earlier mark for identical/similar goods/services, and there is a likelihood of confusion
- Section 5(3) — The mark is identical/similar to an earlier mark with a reputation, and use would take unfair advantage or be detrimental to the earlier mark
- Section 5(4) — The mark conflicts with an earlier right (e.g., passing off, copyright, design right)
Absolute Grounds (Section 3)
Third parties can also oppose on absolute grounds that the examiner may have missed:
- Lack of distinctiveness
- Descriptiveness
- Bad faith filing
- Deceptive marks
The Opposition Process: Step by Step
Step 1: Filing the Opposition (Form TM7)
The opponent files Form TM7 with the UKIPO, setting out:
- The earlier mark(s) relied upon
- The grounds of opposition
- The goods/services opposed
- A statement of the case
Filing fee: From 1 April 2026, GBP 125 if the opposition relies only on Section 5(1)/(2) (likelihood of confusion), or GBP 250 if it includes any other ground (e.g., Section 5(3) reputation, Section 5(4) passing off, or Section 3 absolute grounds such as bad faith). There is no separate per-mark fee for additional earlier marks relied upon.
Step 2: Notification and Cooling-Off Period
The UKIPO notifies the applicant and sets a cooling-off period (typically 9 months, extendable). During this time:
- Both parties are encouraged to negotiate
- The applicant can voluntarily withdraw or narrow the application
- The opponent can withdraw the opposition
- Many oppositions settle during this period
The GTC advantage: Our trademark opposition service includes expert negotiation during the cooling-off period, often resolving disputes without the cost of full proceedings.
Step 3: Evidence Rounds
If no settlement is reached, the case proceeds to evidence:
- Evidence in support — the opponent files evidence supporting their case (typically 3 months)
- Evidence in defence — the applicant files evidence in response (typically 3 months)
- Evidence in reply — the opponent can file further evidence in reply (typically 3 months)
Step 4: Decision
The Hearing Officer reviews the evidence and written submissions. Options include:
- Written decision based on papers only
- Oral hearing if requested by either party
Step 5: Costs
The UKIPO typically awards costs to the successful party on a standard scale (not actual costs). Typical awards:
- Simple case: GBP 1,000–2,000
- Complex case: GBP 2,000–3,000
- Maximum typical award: ~GBP 3,500
Proof of Use Defence
If the opponent's earlier mark has been registered for 5 years or more, the applicant can request proof of genuine use under Section 6A TMA 1994.
The opponent must then demonstrate that the earlier mark has been genuinely used in the UK for the goods/services relied upon within the 5-year period preceding the application date (or publication date).
If the opponent cannot prove use, the opposition fails (or is limited to the goods/services for which use is proven).
Defending Against Opposition
Strategy 1: Challenge the Grounds
Analyse whether the opposition is well-founded:
- Is the earlier mark genuinely similar?
- Do the goods/services actually overlap?
- Does the opponent's mark have a genuine reputation (for Section 5(3) claims)?
Strategy 2: Negotiate a Coexistence Agreement
Many oppositions resolve through coexistence agreements where both parties agree to use their marks with limitations:
- Different goods/services
- Different geographic areas
- Different trade channels
Strategy 3: Narrow Your Application
If the conflict is limited to specific goods/services, consider narrowing your specification to remove the overlap.
Strategy 4: Request Proof of Use
If the opponent's mark has been registered for 5+ years, requiring them to prove genuine use can significantly weaken their case.
Strategy 5: Cross-File Cancellation
If you believe the opponent's mark is vulnerable (non-use, generic, bad faith), you can file a cancellation action against their mark.
