Actavis UK Ltd and others v Eli Lilly & Co

Patent – Infringement. The Patents Court made rulings in proceedings concerning a patent owned by the defendant company, Eli Lilly, for a product used to treat lung cancer. It held that declarations of non-infringement would be granted in respect of each of the four designations of the patent in issue. Both parties would have permission to apply to the court in the event of a material change of circumstances. Further, declarations were made that two letters sent by Eli Lilly in the course of proceedings did not constitute legally binding undertakings.
