The world’s most innovative companies seek Dave’s advice not only because of his strong command of the law and strategic vision, but also because of his unsurpassed technical expertise. He is a former National Science Foundation Graduate Fellow with an undergraduate degree in physics from Yale University and graduate work in string theory at the world-renowned physics department at Princeton University. He understands most complex technologies with ease and translates them to trial themes that win. He has represented companies in a variety of technologies including cloud computing, natural language processing, machine learning, wearable tech, medical devices, cryptography, telecommunications, database management and business intelligence, e-commerce, and software and hardware design.
“Fenwick sets a gold standard for patent litigation. They understand technology and patent law as well as, or better than, anyone in the industry. They can position a case for trial appropriately, win it at trial for you, defend that win on appeal for you, and maybe get your fees to boot.”
