StoneTurn Group is pleased to announce that three of our partners have been recognized among the top patent damages experts in the U.S.

Over a period of five months, Intellectual Asset Management (IAM) interviewed hundreds of attorneys, patent attorneys and in-house counsel across the country to compile the 2014 IAM Patent 1000 — The World’s Leading Patent Practitioners. Each of the experts listed received sufficient positive feedback from peers and clients with knowledge of their practice and the market in which they operate to qualify for the recognition.

CHRISTOPHER MARTINEZ, ALAN RATLIFF and AMBREEN SALTERS, who regularly serve as experts in patent infringement litigations, appear on the short list of the top 43 U.S. patent infringement damages experts.

According to IAM Patent 1000:

StoneTurn Group co-founder Christopher Martinez has broad IP expertise and is called upon to advise on the valuation, licensing and management of patent and other IP assets. “Putting aside his intelligence and appropriate demeanor, he is a former in-house licensing executive with a deep insight; judges are increasingly looking for people with relevant experience over and above an economics background, and Martinez is really coming into his own now — a top choice.”

A forensic accounting, economics and valuation expert with StoneTurn Group, Alan Ratliff “prepares five-star expert reports and, moreover, is phenomenally good in court. He lays out his logic early and is very confident, meaning he holds up superbly under tough cross-examination.”

Houston-based StoneTurn partner Ambreen Salters “possesses the combination of skills and personality that you just have to have; she has the right background and is likeable, articulate and able to present a complex damages case in a straightforward way.” She provides a wide range of economic analyses in patent disputes and has experience in an array of different industry sectors.

“I am extremely pleased that Chris, Alan and Ambreen have been named among the top patent damages experts by IAM,” said Simon Platt, Managing Partner of StoneTurn Group. “Inclusion on this list is a very well-deserved recognition of our partners’ expertise, their client service focus and the strength of the teams supporting them.”

StoneTurn’s INTELLECTUAL PROPERTY experts provide a range of litigation support and transactional services to clients ranging from Fortune 500 multinational corporations to start-up organizations. Drawing upon experience in licensing, economics, law, finance and accounting, we are able to advise clients on patent infringement, copyright infringement, trademark infringement and Lanham Act actions, trade secret misappropriation and licensing disputes.
