Legal Principles
Threshold test for interim injunctions: 'serious question to be tried' and 'real prospect of success at trial'.
American Cyanamid Co v Ethicon Ltd [1975] AC 396
Summary judgment in patent cases: generally inappropriate due to the need for expert evidence on claim construction and infringement, unless the issues are straightforward.
Nampak Plastics Europe Ltd v Alpla UK Ltd [2014] EWCA Civ 1293; Shenzhen Carku Technology Co, Ltd v The Noco Company [2020] EWHC 2104 (Pat); Virgin Atlantic Airways Ltd v Delta Airways Inc [2011] EWCA Civ 162
Doctrine of equivalents: infringement can be found even if the claims are not literally infringed, if the differences are non-essential.
Actavis UK Limited v Eli Lilly and Company [2017] UKSC 48
Interim injunctions: balance of convenience, irreparable harm, and the ability to compensate.
American Cyanamid Co v Ethicon Ltd [1975] AC 396; National Commercial Bank Jamaica Ltd v Olint Corpn Ltd (Jamaica) [2009] UKPC 16
Outcomes
CCL's application for summary judgment was dismissed.
The court found that the issues of claim construction and potential infringement by equivalence were not suitable for summary determination due to the need for expert evidence and clarification of the parties' cases.
Verifi and GCP's application for an interim injunction was dismissed.
While GCP faced potential irreparable harm from price depression due to CCL's lower-priced system, the court found that the risk of substantial harm was relatively low, particularly considering the short timeframe until trial and the potential for calculating damages. The court considered the greater potential harm to CCL's precarious financial position if an injunction was granted.
