Chewing the fat over the High Court's judgment on the world's best-selling drug

The English Patents Court has recently refused a declarationof non-infringement in relation to the compound patent coveringAtorvastatin (Lipitor), the world's best-selling drug, but founda patent relating to its hemicalcium salt invalid for lack ofnovelty and obviousness; this decision is seen as a victoryfor Pfizer since the invalidation of the hemicalcium salt patenthas not shortened its period of exclusivity.     

Walking the groundless threats minefield

Legal context. It is one of the peculiarities of UK law thatthreatening litigation of IP rights can, in some circumstances,give rise to an action for "groundless threats". This has thepotential to cause great disruption to the right-holder's case.There is even the potential for professional advisors to endup in the dock where they made the threat on their client'sbehalf, raising the possibility of a conflict of interest preventingthe advisers from continuing to act. Key points. To minimise the risk of these scenarios, intellectualproperty law advisors, be they patent or trade mark attorneysor solicitors, should be aware of the provisions that governgroundless threats actions for the various IP rights, particularlyin light of the recent changes brought in by the Patents Act2004 and the further changes expected to the groundless threatsprovisions relating to designs. These alterations increasinglycomplicate what has always been a nebulous area of the law.In addition, there is considerable tension between the "talkfirst, sue later" philosophy underlying the Civil ProcedureRules and the "sue first, talk later" approach traditionallyused to circumvent threats actions. Reckitt recently confirmedthat the groundless threats provisions, while running counterto the purpose of the CPR, cannot be ignored by the Courts.This article provides an overview of the current state of thegroundless threats provisions that apply to the various IP rights,and considers how IP owners and their advisors can best navigatethe groundless threats minefield. Practical significance. Groundless threats form a complex andchanging area of IP law in the UK, which advisers need to takeinto account in virtually every dispute. Amendments made toSection 70 of the Patents Act 1977 have not provided a threatspanacea to patent holders and it remains to be seen how thesection will be interpreted by the Courts. What is clear isthat the threats provisions contained in the IP legislationwill remain in force in one form or another for the foreseeablefuture and that they remain a trap for the unwary.
