Medical doctor William Noonan heads an exciting life sciences practice and undertakes high-profile work supporting the National Institutes of Health and the Food and Drug Administration, among many others. Meanwhile, anchoring a potent litigation unit that performs exquisitely on the national stage are John Vandenberg, Scott Davis and Jeffrey Love. “John and Scott demonstrate in-depth knowledge, amazing strategic aptitude and a calm and rational approach to difficult challenges. Their handling of a case is second to none.” The recipient of special praise during the IAM Patent 1000 research cycle, Vandenberg is a “truly exceptional lawyer. He is incredibly efficient and gets excellent results at low cost. He thinks carefully about each case to determine how business objectives are best achieved – nothing is done by rote – and he comes up with novel ideas that win. More than any other lawyer, he puts himself in his client’s shoes, which drives his creativity and results in first-rate substantive work”. He and Love secured a wonderful result for Mentor Graphics against Synopsys, invalidating the claims of three of the latter’s patents under Section 101.
