Actavis UK Ltd & Ors v Eli Lilly & Company [2015] EWCA Civ 555 (25 June 2015)

Actavis UK Ltd & Ors v Eli Lilly & Company [2015] EWCA Civ 555 (25 June 2015)

The claims of the 508 patent are limited to 'pemetrexed disodium' and do not extend to other salts or forms such as pemetrexed diacid, dipotassium, or ditromethamine. The skilled team includes both an oncologist and a chemist, and the chemist could not predict without testing that the variants would have no material effect on the way the invention works. Therefore, Actavis' proposed products do not infringe the 508 patent under English law or the corresponding foreign laws. The prosecution history does not justify a broader construction. English law applies to the procedural conditions for declaratory relief under Rome II, and Actavis satisfied those conditions.

Ratio Decidendi

The claims of the 508 patent are limited to 'pemetrexed disodium' and do not extend to other salts or forms such as pemetrexed diacid, dipotassium, or ditromethamine. The skilled team includes both an oncologist and a chemist, and the chemist could not predict without testing that the variants would have no material effect on the way the invention works. Therefore, Actavis' proposed products do not infringe the 508 patent under English law or the corresponding foreign laws. The prosecution history does not justify a broader construction. English law applies to the procedural conditions for declaratory relief under Rome II, and Actavis satisfied those conditions.

Court Disposition

Appeal dismissed; declarations of non-infringement upheld.
