Declaratory Judgment Burdens

Medtronic v. Boston Scientific

• "The substantive burden of proof normally does not shift simply because the party seeking relief is a counterclaiming defendant in a declaratory judgment action."
• "[T]his court holds that in the limited circumstance when an infringement counterclaim by a patentee is foreclosed by the continued existence of a license, a licensee seeking a declaratory judgment of noninfringement and of no consequent liability under the license bears the burden of persuasion."
