    • Sanofi-Aventis U.S. LLC et al. v. Merck Sharp & Dohme Corp. (D. Del.). Represented Merck as trial counsel responsible for establishing Merck’s non-infringement arguments concerning its insulin glargine 505(b)(2) product.

The case settled prior to receiving the District Court’s decision. 
    • Amgen Inc. et al. v. Hospira, Inc. (D. Del.). Represented Amgen against Hospira who sought to launch a generic of Amgen’s Epogen® product. Dr. Antons deposed key witnesses and secured important admissions related to whether 14 batches of drug substance for Hospira’s EPO biosimilar product were prepared under a Safe Harbor Provision. These 14 batches were found to not be subject to the Safe Harbor Provision, and the jury ultimately awarded a US$70 million verdict for Amgen. In a noteworthy opinion, the Federal Circuit affirmed that award.
