Steven Kursh was an outstanding technical expert on our ecommerce IP lawsuit. He completed a massive amount of work on extremely complicated material, in a very short period of time. His work product was first rate and I think he would have done a terrific job if the case proceeded to trial. He is very articulate and helped us. I only wish we had gotten him involved sooner in the litigation.”

When we needed an expert in a patent infringement lawsuit, we turned to TASA. We were looking for a witness qualified in two unrelated technical areas, and TASA worked with us to identify and refine our requirements. TASA performed well, promptly providing us with several excellent candidates to consider, one of whom we retained."
