Dr. Daniel Kazhdan's practice focuses on pharmaceutical litigation in federal district courts and on IP appeals. He has substantial experience working on all phases of pharmaceutical litigations, from leading pre-suit investigations and discovery all the way through drafting numerous Federal Circuit appeals.

Daniel's practice combines his deep understanding of chemistry that he developed through his doctoral work at Berkeley along with his familiarity of patent law and the federal court system that was sharpened by his clerkship at the Federal Circuit.
