NEW YORK — April 14, 2005 – LAWFUEL – The international law firm of Chadbourne & Parke LLP today announced that Joseph A. Calvaruso, Walter G. Hanchuk and Kenneth S. Weitzman have joined the Firm as partners in the intellectual property practice, effective April 13. They are resident in the Firm’s New York office. Prior to joining Chadbourne, all were partners in the New York office of Morgan & Finnegan, an intellectual property firm.

“One of the Firm’s major objectives is to continue to grow a world class, full service intellectual property practice,” said Charles K. O’Neill, Chadbourne’s managing partner. “This premier group will play a vital part in that strategic growth and in our continued commitment to build the IP practice as we move forward. We are tremendously pleased to have these outstanding partners join the Firm.”

Mr. Calvaruso is an internationally well known IP litigator and is featured in Best Lawyers in America. Mr. Calvaruso has over 25 years of experience in virtually all aspects of intellectual property. His litigation experience, in both federal courts throughout the United States and before the International Trade Commission, covers a wide spectrum including patents, trade secrets, trademarks, trade dress, antitrust, false advertising and unfair competition. Mr. Calvaruso’s patent experience has covered diverse fields, such as medical devices, consumer products, automotive parts, electronics, telecommunications, semiconductor devices and fabrications, and computer technology and software. In addition to litigation, Mr. Calvaruso has done extensive work in IP due diligence and licensing. He also advises clients as to patent infringement and validity issues and handles prosecution.

Mr. Calvaruso received a B.S. degree in electrical engineering from Manhattan College, and his J.D. from Fordham University School of Law.

Mr. Hanchuk has over 15 years of experience in all aspects of intellectual property law. He has been actively involved in all phases of patent litigation in federal courts. He also has extensive licensing and transactional experience. Early in his career, he served as a U.S. Patent Examiner at the U.S. Patent & Trademark Office. In recent years, he has been particularly successful in obtaining, licensing and enforcing worldwide intellectual property rights in the information technology and financial service sectors. Having been actively involved in various ‘pioneering’ business process and computer software patents, he continues to publish and speak widely on the topic.

He received his B.E. in mechanical engineering from The Cooper Union, and J.D., cum laude, from George Washington University Law School.

Mr. Weitzman has over 13 years experience representing clients in nearly all aspects of intellectual property law. He specializes in patent infringement litigation in federal courts across the country, both at the trial level and on appeal. He also has extensive experience counseling clients on issues of infringement and validity of U.S. patents, procurement of patents before the U.S. Patent & Trademark Office, trademarks and other intellectual property matters. Mr. Weitzman has litigated, prosecuted and rendered opinions in patent matters, involving a wide array of technologies, including medical devices, automotive products, computer software, e-commerce and financial services, consumer products, semiconductors and telecommunications systems.

Mr. Weitzman received his B.S. in mechanical engineering from the University of Massachusetts, and his J.D., cum laude, from Seton Hall University School of Law.

“These lawyers are extremely knowledgeable in intellectual property matters and have experienced first-hand the business and IP challenges that U.S. and international clients face every day,” Mr. O’Neill noted. “Their representation of major high-technology companies and financial institutions will complement our established patent litigation practice.”
