Chares 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.
