SONA DE is an experienced trial lawyer who has led numerous victories in both bench and jury trials and on appeal before the Federal Circuit. Her cases span a wide range of technology sectors, with a focus on biologics, pharma/Hatch-Waxman litigation, medical devices/med-tech, crop science, and chemicals. Her work across these sectors is well recognized.
In biologics, Sona represented Bayer HealthCare in its jury trial win against Baxalta’s flagship hemophilia product. She delivered a closing argument that defeated Baxalta’s defenses for a complete victory across every liability issue, leading to the largest damages verdict from a Delaware jury for a biologic. The case won LMG Life Sciences’ 2019 “Patent Impact Case of the Year,” was selected as a “Legal Lion” by Law360 for continued success in post-trial motions, and was widely reported in the press.
Sona also represented Amgen/Immunex in its trial win against Sandoz’s biosimilar of Enbrel®, the first time a biologics maker has fully succeeded in blocking a biosimilar under the Biologics Act through the courts. Following a stipulation on infringement and a nearly month-long trial on numerous validity challenges, the district court found in Amgen’s favor across the board. The Federal Circuit affirmed. The case won LMG Life Sciences’ 2020 “Impact Case of the Year.”
In the medical device/med-tech space, Sona was featured as The American Lawyer’s “Litigator of the Week” and received the Financial Times’ highest ranking for her innovative strategies and success in the landmark Therasense case involving glucose metering technology that created a new legal standard for the inequitable conduct doctrine. Therasense has been named as one of the top 10 patent decisions of this decade by Law360.
In Hatch-Waxman litigation, she was profiled by InsideCounsel for her role in Bayer HealthCare’s trial win on a formulation patent based on the doctrine of equivalents. Her work for Purdue in serial trials against multiple generics on three different patent families also won LMG Life Sciences’ 2013 “Hatch-Waxman Impact Case of the Year.”
Sona has also argued before the Federal Circuit Court of Appeals and the Multidistrict Litigation Panel, represented clients in arbitration, and defended witnesses overseas under the Hague Convention. She has been recommended in Healthcare: Life Sciences in The Legal 500 US; is recognized for her patent litigation work by the IAM Patent 1000 (2017-2018, 2020); is recognized among “The Top Women Attorneys in the New York Metro Area”; was shortlisted for LMG Life Sciences’ 2017 “General Patent Litigator of the Year” in New York and named in the 2019-2020 LMG Life Sciences guides for intellectual property; and has received In Motion’s “Commitment to Justice Award.” Her prior work experience in the pharmaceutical industry enables Sona to represent clients on various patent issues with an understanding of how companies operate with an eye towards their business needs.
