The team excel at complex medical technology and high-technology patent trials, maintaining relationships with notable clients, including Comcast Cable Communications, Google, and T-Mobile. Leading the practice are four specialists. Amy Wigmore, based in Washington DC, and Emily Whelan, based in Boston, both specialize in high-stakes litigation within the pharmaceutical and biotechnology industries. They are joined by Mark Selwyn, a leading attorney for both high-profile and emerging technology companies and Joseph Haag, both of whom are based out of Palo Alto. The team is further bolstered by William Lee, from Boston, renowned for his seasoned experience as lead counsel in high-stakes technology disputes. Elsewhere, Brittany Amadi, from Washington DC, and Joseph Mueller, based in Boston, stand out for their leading work on patent litigation matters at the trial and appellate stages. First-chair trial attorney Sonal Mehta is another key practitioner from Palo Alto representing notable technology companies on high-stakes disputes. Additionally, Boston’s Omar Khan extends the team’s offering with his expertise in life sciences cases.
