Selected Prior Experience

Biosimilar Competition

Dr. Saha provided expert testimony in a dispute involving biosimilar competition for a blockbuster biologic pharmaceutical drug, Remicade. Dr. Saha’s testimony was supported by analysis of sales and pricing data on biologic and biosimilar sales in various countries. This analysis provided understanding of the implications of the biosimilar launch in the US. The team supporting Dr. Saha worked closely with attorneys from Kirkland & Ellis and Winston & Strawn.


Mr. Rinaudo provided testimony to oppose sentencing on behalf of Michael Coscia, the first trader convicted of spoofing. Mr. Rinaudo led a team that analyzed over 1 billion market records across 14 commodities markets to present the court with a context in which to frame the defendant’s trading behavior. Working closely with lawyers from Dentons and Kobre Kim, Mr. Rinaudo was part of the team that helped to get Mr. Coscia’s sentence reduced from the 80 months requested by the government to 30 months.

Independent Investigation

Dr. Saha and Mr. Rinaudo were selected by New York State and major tobacco manufacturers to undertake the periodic estimation of Native American brand cigarettes sold on Reservations in New York State. DSP worked closely with the independent investigator, Nardello & Co. to evaluate submissions by the parties, evaluate available data, develop protocols to gather additional data through surveillance and ultimately develop a range of estimates based upon different data sources.
