Patent – Swiss form claim. The claimant company, W-L, owned the patent for a drug. The patent protection for the drug had lapsed, although W-L still had a medical use patent for one of the three areas in which the drug was used. The defendant company, Actavis, sought to market a generic drug for similar complaints, but there was concern that it might be prescribed by mistake to patients using W-L's protected use. W-L brought proceedings seeking interim relief pending proceedings for infringement of patent. The Patents Court held that the claim did not raise a serious issue to be tried.
