United States: Expert witnesses

Economic analysis often plays a crucial role in IP litigation, whether relating to the question of reasonable efforts in licensing disputes, commercial success in disagreements over patentability or most importantly, the quantum of damages to be paid for lost profits and as a reasonable royalty in infringement suits. Given the importance of patents as business assets and the significant sums at stake in compensation battles, choosing the right expert witness is imperative. The IAM Patent 1000 presents a list of the leading professionals in this field arranged alphabetically by firm.
