Seasoned Patent Attorney Guy Chambers Joins Sideman & Bancroft

June 2014

Sideman & Bancroft LLP announced today that patent attorney Guy W. Chambers has joined the firm’s Intellectual Property and Litigation Groups as Partner. Mr. Chambers comes to Sideman from Duane Morris LLP, where he was a Partner in the firm’s San Francisco office.

Mr. Chambers focuses his practice on patent litigation, patent prosecution, patent licensing, contested Patent Office proceedings, and other intellectual property disputes. He has served as lead counsel in more than 40 intellectual property lawsuits and Patent Office interferences, and has successfully prepared and prosecuted patents in the fields of medical devices, mechanical devices, telecommunications, electronics and biotechnology. Representing clients in actions in U.S. District Courts, the U.S. International Trade Commission, the U.S. Patent and Trademark Office and the U.S. Court of Appeals for the Federal Circuit, Mr. Chambers has obtained successful outcomes in eight of the nine cases that went to trial and nearly all of the Patent Office interferences he has handled.

“Guy has an incredible track record of successfully advocating for his clients in complicated patent cases,” said Intellectual Property Partner Kelly McCarthy. “His years of experience and expertise in the area of patent law will be invaluable as we continue to build out our offerings in the IP space. We’re glad to have him on board.”

Before joining Duane Morris, Mr. Chambers was a Partner at Townsend and Townsend and Crew LLP (now Kilpatrick Townsend & Stockton LLP), during which time he served as the project manager on a patent services contract with the National Institutes of Health. Prior to that role, he was a Trial Attorney in the Honors Program at the United States Department of Justice.

“I am excited to add my diverse patent skills to Sideman’s growing intellectual property group, which has already developed a strong reputation for its trademark and anti-counterfeiting work,” said Guy Chambers.

Mr. Chambers has authored several articles on patent litigation and licensing in publications such as The Recorder and Daily Journal and frequently speaks at industry events. From 2001 to 2010, he was a Faculty Lecturer at Practising Law Institute’s Advanced Patent Licensing seminar. In 2009, he co-chaired Law Seminars International’s workshop on “Patent Claim Construction” and also served as a Faculty Lecturer at Santa Clara Computer & High Technology Law Journal’s “Shifting Strategies in Patent Law” symposium.

In 2012 and 2013, Mr. Chambers was selected for inclusion in Northern California Super Lawyers in the field of Intellectual Property Litigation. He has also appeared in The Legal 500, Marquis’ Who’s Who in American Law, and Bay Area Lawyer Magazine’s “Best Lawyers in the Bay Area” for his litigation practice.

Mr. Chambers earned his J.D. in 1981 from Columbia University School of Law and a B.S. in Chemical Engineering from University of California, Santa Barbara in 1978, with highest honors.
