The Patent 1000 focuses exclusively on patent practice and has firmly established itself as the definitive 'go-to' resource for those seeking world-class legal patent expertise.

Recommended - Economic experts

“Berkeley Research Group is a go-to for all aspects of patent valuation, from licensing and acquisition strategy to damages theories and economic assessments. It has ample bench strength, and the quality of its patent damages team is outstanding; they have shown noted strength in crafting economically rigorous theories that have fared well in Daubert proceedings and in jury trials. The team are responsive, professional and provide overall great support.” Adept at analysing highly complex matters, co-founder and leader of the firm David Teece is a distinguished and prominent academic. Leader of the group’s IP practice, Jeffery Stec brings wisdom distilled from two decades in the game to deliver a high-quality service as a consulting expert and expert witness. Stec also has experience in the context of Section 337, as does Joshua Lathrop. Lathrop brings sophisticated expertise carefully refined from his preparation of expert analyses in more than 90 litigation and arbitration matters; he has recently linked up with the eminent Catharine Lawton on a case relating to MoCA functionality used in cable set-top boxes. Clients are especially effusive in their praise of Lawton: “Catharine is the most impressive expert witness out there. She is proactive, exceedingly thorough and detail oriented. Her reports are comprehensive and her demeanour as a witness is professional and unflappable. She has an amazing memory for detail, an exceedingly high work ethic, and the ability to take all the information that she has researched and present it in a well-conceived, logical opinion.” David Kennedy and Rebbecca Reed-Arthurs make their IAM Patent 1000 debuts this year. Kennedy can be found masterminding IP-related transactions and patent portfolio valuations. Reed-Arthurs earns glowing praise from one source: “Rebbecca excels in mastering voluminous data and understanding the complicated environments present in patent litigation. She is a credible testifier who brings both gravity and dynamism to the courtroom, with a special touch to hold the interest of the jury. Because Rebbecca has such a strong command of her reports and underlying documents, cross-examinations of her come off as non-events. She is also a delight to work with and is always timely with deadlines and meeting expectations.” Recently joining the team from Ankura Consulting, Walter Vandaele is a big-picture thinker with sharp analytical skills.
