Tessera Appoints Bernard Cassidy as Senior Vice President and General Counsel

Cassidy succeeds Scot Griffin, who was promoted to executive vice president of Micro-electronics, and is responsible for the company's semiconductor packaging technology businesses. Griffin remains responsible for Tessera's current legal efforts to protect its chip scale packaging (CSP) intellectual property.

"We are delighted Barney has agreed to join the Tessera management team," said Nothhaft. "He brings to Tessera more than 20 years legal experience, including intellectual Property Management, mergers and acquisitions, corporate governance and public company regulatory compliance. His solid legal background makes him an ideal fit for Tessera."

"Tessera has industry-leading expertise in licensing and protecting its valuable intellectual property, and developing and acquiring complementary technologies," said Cassidy. "I look forward to working with the team to help further expand Tessera's innovation worldwide."

Cassidy, 54, joins Tessera from Tumbleweed Communications Corp., an enterprise software company, where he was senior vice president and general counsel until the company was acquired by Axway, Inc. Prior to Tumbleweed, Cassidy practiced law both at Wilson, Sonsini, Goodrich and Rosati in Palo Alto, California, and at Skadden, Arps, Slate, Meagher and Flom in San Francisco, California.

Cassidy holds a J.D. from Harvard Law School, where he was an editor of the Harvard Law Review and a research assistant to Professor Arthur R. Miller. Immediately after law school he served as a law clerk to the Honorable John T. Noonan, Jr. of the U.S. Court of Appeals for the Ninth Circuit in San Francisco, California. He also holds a M.A. in Philosophy from the University of Toronto and a B.A. in Philosophy from Loyola University.
