Sanofi-Aventis Deutschland GMBH v. Glenmark Pharm. Inc., USA, 748 F.3d 1354 (Fed. Cir. 2014)

Key Insight: Concluding that trial court did not err in giving permissive adverse inference instruction where defendant failed to suspend its email retention policy (whereby all emails and related electronic documents were retained for only one month) at the point when patent infringement litigation became reasonably foreseeable, i.e., the earliest date asserted by defendant for work product protection in its privilege log, appellate court commented: “The destruction of documents in the course of preparation for litigation has no entitlement to judicial protection, and need not be concealed from the jury.”
