Neutral citation: [2017] EWHC 1695 (IPEC)
Overall AI summary confidence: high
Short overview
This short overview is intended to summarise the case, issues and outcome so far as they are supported by the judgment.
AI confidence in this short overview: high
This case concerned Coreix Ltd's claims that defendants' use and registration of CORETX infringed its earlier COREIX mark and amounted to passing off. The court found infringement under s.10(2) (likelihood of confusion) and s.10(3) (reputation, link and detriment), and upheld passing off; it also declared D3's CORETX registration invalid and found the defendants' domain-name use infringed and passed off. Defences of estoppel/acquiescence failed and no finding of infringement/passing off was made against D5 for the short period it used a Coretx-derived name.
Ratio decidendi
This summary is intended to identify the ratio decidendi, meaning the legal reasons for deciding and the binding part of the decision.
AI confidence in this ratio decidendi summary: high
The judgment applies that close visual, aural and conceptual similarity combined with identity of services, supported by evidence of actual confusion, establishes a likelihood of confusion under s.10(2). For s.10(3), an earlier mark’s UK reputation plus a link in the mind of the average consumer can found liability where detriment to distinctive character is shown by change in economic behaviour (or a real risk thereof). Estoppel/acquiescence cannot defeat a national trade mark infringement claim and, as equitable defences to passing off, require clear encouragement/representation and proven reliance.
Obiter dicta
This summary is intended to identify obiter dicta, meaning observations made by the way that were not necessary to deciding the case and are not binding.
AI confidence in this obiter dicta summary: medium
The court noted (obiter) that limited side-by-side use can still produce confusion where real opportunities for mistake exist (e.g. shared data-centre contexts), and that small documentary incidents can corroborate confusion evidence. It also observed that non-attendance of a key witness may justify scrutiny of evidence but adverse inferences should not be drawn without proper pleading and fairness.
