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 negotiates and drafts 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 associate adjunct professor at Brooklyn Law School, where he designed and teaches a course on food and drug law.

Mr. Weiss has been recommended in Intellectual Asset Management (IAM) Patent 1000 since 2011. In 2015, it wrote: "Holland & Knight's Charles Weiss retains his silver-tier litigation ranking this year and also moves up the highly recommended level for patent transactions. 'Across all areas, he stands out consistently for his business-savvy approach, his ability to act as a part of your in-house team  and his tenacity and credibility. His technical knowledge is amazing, too – he frequently impresses scientists with a grasp of what they consider to be esoteric or little-known concepts and he          never seems to forget anything once he’s learned it. He has a very wide and deep pool of litigation experience that he brings to bear in recognizing pitfalls and providing thoughtful, battle- tested solutions.'"
