Court of Appeal upholds the High Court's decision that the patent for a widely-used anti-coagulant medicine is invalid, thus invalidating the associated Supplementary Protection Certificate; but the court grants an injunction restraining a generic pharmaceutical company from launching a competing product until the appeal is determined, recognising the potential for irreparable harm to the patent holder's market position and exclusivity rights.
