Charles A. Weiss is a partner in Holland & Knight's New York office and head of the New York Intellectual Property Group. He concentrates his practice on technology-driven litigation, counseling and transactions, primarily in the pharmaceutical, chemical and biotechnology areas. He also counsels clients on questions of patent validity and infringement, and provides a litigator's perspective on prosecution matters.

Mr. Weiss litigates patent, trade secret, license and false advertising cases in diverse technical areas. He has handled cases over the years involving expression of recombinant proteins and antibodies, controlled release pharmaceuticals, medical diagnostic agents, endocrine and hormone products, nutritional supplements, industrial control systems, food chemistry, nucleic acid diagnostic assays and commercial detergents. He also has extensive experience in the investigation of product counterfeiting and pursuit of those responsible.

In addition, Mr. Weiss has a diverse non-litigation practice, focused on supporting transactions in which a substantial value is attributed to a party's patent position, such as its ability to exclude competitors or to bring its product to market free of meritorious infringement claims by others. He has negotiated and drafted licenses and other agreements, including commercial collaboration, joint research and product acquisition agreements, and regularly advises financial professionals on the strength or vulnerability of a target company's patent positions.

Mr. Weiss also has experience in commercial matters, including corporate and securities transactions, contract litigation, insurance and banking disputes, construction litigation, accounting and attorney malpractice, and investigations of employee malfeasance and fraud. Mr. Weiss is an adjunct professor at New York Law School, where he designed a course on patent litigation and analysis, and is also an associate adjunct professor at Brooklyn Law School, where he designed and teaches a course on food and drug law.
