Abstract
The Supreme Court’s 2015 decision in Teva Pharmaceuticals v. Sandoz brings the standard of review of patent construction rulings into line with foundational juridical principles of appellate review, resolving one of the most divisive issues in patent litigation over the past two decades. This article shows that the decision's efficacy depends critically upon how district courts adapt their case management. District judges will need to implement effective procedures for ferreting out subsidiary factual disputes bearing on claim construction, scour the intrinsic evidence for contraindications, develop a sufficient evidentiary record for resolving the dispute, and explain their analysis. The article also explores the interplay of claim construction and claim indefiniteness.
