Recent Accolades and Media
“David served as an expert witness in a complex copyright matter involving ownership, validity and infringement issues. He was not only excellent in explaining the technical issues in his report and in his trial testimony, but he also took the time to really understand the legal context of where his opinions fit into the rest of the case. His visual depictions of the products at issue were clear and understandable for the jury and the judge. Although his thorough preparation limited the areas of surprise, David handled any unexpected issues on cross examination easily by being forthright and honest, and that was clearly appreciated by both the jury and the judge. He was also very flexible when some difficult scheduling issues arose in the case.”
