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.

Mr. Weiss also 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.

Eric Huang is a partner in Quinn Emanuel's New York office.  He represents both plaintiffs and defendants in intellectual property matters.  He specializes in building patent infringement cases on either side of the “v” in highly technical subject matter.  He has extensive experience litigating patent cases involving a wide range of technologies – smartphones, user interface software, touchscreen technology, circuits, semiconductor processing, spreading and modulation techniques used in wireless communication, various aspects of 3G and 4G cellular communications, error control coding including turbocodes and low density parity check codes, digital video compression, audio compression, pharmaceutical formulations, fiber optics, liquid crystal displays, mechanical measurement devices, electronic engine control, e-commerce, and computer systems. 

His practice encompasses all aspects of case preparation, pre-trial discovery, expert preparation, trial preparation and trial in U.S. federal district courts and before the U.S. International Trade Commission.  He served as a trial counsel for respondent Samsung in ITC investigation 337-TA-796 initiated by Apple against Samsung's smartphones, tablets and media players.  The firm successfully defended against efforts to stop the importation of Samsung devices; to date, no Samsung device was excluded or seized as a result of any order from this investigation.  Eric recently helped secure a very favorable jury verdict for Marvell Semiconductor in a case brought by France Telecom in San Francisco federal district court alleging infringement by Marvell’s 3G baseband chips.  In addition to a favorable damages verdict of a fraction of the damages sought by plaintiff, the firm recently secured judgment for Marvell Semiconductor on post-trial motions in that case.  Eric also has experience prosecuting patents and is admitted to the U.S. Patent & Trademark Office.
