Appeals court affirms Dow's victory in PE patent case

摘要

Dow Chemical Co. has won an appeals court ruling upholding a 2010 verdict totaling $76 million against Nova Chemicals Corp. in a patent conflict over enhanced polyethylene resins. Athree-judge panel in the U.S. Court of Appeals in Washington awarded Midland, Michigan based Dow $61.7 million in damages plus additional interest for the $76 million total. Dow had argued that Nova's Surpass-brand enhanced PE violated patents for Dow's Elite-brand enhanced PE.
