Federal Circuit Court Addresses Key Damages Issues in Vacation $386 Million Patent Verdict
Time 1 Minute Read

This week, the US Court of Appeals for the Federal Circuit issued a precedential decision addressing two important patent damages issues: the entire market value rule and the proper application of the Nash Bargaining Solution in VirnetX, Inc. v. Cisco Systems, Inc., No. 13-1489 (Fed. Cir. Sept. 16, 2014). In vacating a $386 million damages award against defendant Apple Inc., the Federal Circuit first resolved conflicting treatment of the application of the entire market value rule (EMV) by the district courts in cases where the smallest saleable unit is the entire accused device. Holding that the district court’s jury instruction was improper, the Federal Circuit clarified that, unless the EMV rule is satisfied, damages must always be apportioned between patented and unpatented features—even in cases where the smallest salable unit is the accused device itself. Second, the Federal Circuit held that the patentee’s damages expert had improperly relied on the Nash Bargaining Solution because he failed to sufficiently tie the controversial theory (positing a 50 percent/50 percent profit split between the patentee and accused infringer) to the specific facts of the case.

A recent federal court decision determined that documents created by a criminal defendant using AI and subsequently shared with legal counsel were not shielded by attorney-client privilege or the work product doctrine. In USA v. Heppner, Judge Jed S. Rakoff of the U.S. District Court for the Southern District of New York compelled the disclosure of 31 documents created with Anthropic’s Claude. This order was issued despite the defendant including information from counsel in the AI tool’s input and later providing the resulting outputs to his attorneys. The ruling offers early judicial perspective on privilege concerns involving AI-generated materials, an area where case law remains sparse.
