Extreme Networks Limited v Extreme E Limited
[2024] EWCA Civ 1386
Likelihood of confusion assessment considers the average consumer, nature of purchasing act, and complementary relationship between goods/services.
Trade Marks Act 1994, sections 5(2)(a), 5(3)
Similarity assessment considers whether goods/services are complementary (Canon Kabushiki Kaisha v Metro-Goldwyn-Mayer Inc; British Sugar Plc v James Robertson & Sons Ltd; Kurt Hesse v OHIM; Boston Scientific Ltd v OHIM).
Case law cited in the judgment
Unfair advantage under section 5(3) may exist even without subjective intent to exploit reputation (Jack Wills Limited v House of Fraser (Stores) Limited).
Case law cited in the judgment
Section 5(5) prevents registration only where there's explicit consent from the earlier trademark holder; due cause requires a high threshold (Leidseplein Beheer BV v Red Bull; Zino Davidoff v Levi Strauss; Sebago Inc. and Ancienne Maison Dubois et Fils SA v GB-Unic SA).
Case law cited in the judgment
Appeals against UKIPO decisions are reviews, not rehearings; deference is given to the Hearing Officer's expertise (Reef Trade Mark).
Case law cited in the judgment
Appeal dismissed.
The Hearing Officer's decision was not found to be wrong in principle. The court upheld the findings on similarity of services (based on complementarity) and likelihood of confusion, rejecting the Appellant's arguments regarding judicial notice, the application of the correct legal tests, and the interpretation of the co-existence agreement.
