Charles R. Macedo, a physicist by training, litigates in all areas of intellectual property law, including patent, trademark and copyright law, with a special emphasis in complex litigation and appellate work. Companies and individuals from a wide range of industries turn to him to develop offensive and defensive strategies for the development and enforcement of their patent and trademark portfolios.

Fluent in technical jargon spoken by inventors and clients, patentese spoken at the PTO, legalese spoken by courts and attorneys, business jargon spoken by management, and plain English, he seeks to translate complex subject matter into terms all can understand.

The author of The Corporate Insider's Guide to U.S. Patent Practice, Mr. Macedo has been cited as an authority on intellectual property issues by the Wall Street Journal, Dow Jones, BNA, Bloomberg, Inside Counsel, Managing Intellectual Property, Technology Transfer Tactics, IP Law 360, JIPLP and other media.

His patent experience encompasses a broad range of industries and products including Internet, e-commerce and computer-enabled inventions; financial services, transaction processing, electronic wallets and virtual or synthetic currency, including Bitcoins; Software-As-A-Service; social media; semiconductor and photomasks; green energy and power; construction materials and structures; life sciences; and apparel, to name a few. Mr. Macedo also has enforced and defended against trademark assertions for financial service providers, non-profit organizations, celebrities; cosmetic companies, luxury retailers of designer handbags and retail chains. He also advises clients on IP contracts, licensing and confidentiality agreements.

By identifying vulnerabilities and considering variations on design concepts, Mr. Macedo helps clients develop strategies to maximize protection and prevent infringement challenges. He frequently serves as special counsel to companies seeking an IP strategy, not just a patent; to IP holders in anticipation of litigation and as coordinating counsel for multiple law firms.

He is consistently at the forefront of complex and emerging patent issues in the financial services and transaction processing industries. Clients ranging from international banks, broker dealers and new business ventures call on Mr. Macedo to develop patent strategies, prepare patents, assert rights and defend against infringement claims. His work includes developing and implementing patent strategies associated with such cutting edge financial innovations like bitcoins and other synthetic currency or math-based assets. His experience includes successfully defending the Discover Card division of Morgan Stanley from one of the earliest business method patent assertions, and leading the team to implement and enforce the deposit sweep patent portfolio for Island Intellectual Property LLC. He has also helped clients implementing insurance related products seek patent and other intellectual property protection.

Mr. Macedo writes prolifically and lectures regularly as he tracks and analyzes in real time the most important developments affecting IP strategy and litigation. As Co-Chair of the Amicus Committee of the New York Intellectual Property Law Association, Mr. Macedo has been principal counsel or additional counsel on amicus briefs in some of the leading patent cases of recent years, including Mayo v. Prometheus (at the Supreme Court), Association of Molecular Pathology v. Myriad Genetics Inc. (at the Supreme Court and the Federal Circuit), CLS Bank Int’l v. Alice (at the Federal Circuit en banc and at the Supreme Court in the petition and merits brief stage).  His appellate experience also includes petitions for mandamus, for rehearing before the U.S. Court of Appeals for the Second Circuit and for certiorari to the U.S. Supreme Court on behalf of various clients.

He holds bachelors and masters degrees in physics from The Catholic University of America and a law degree from Columbia Law School, all with honors. He was the sole law clerk to Hon. Daniel M. Friedman of the U.S. Court of Appeals for the Federal Circuit, 1989–1990. The recipient of the prestigious AIPLA Robert C. Watson Award, Mr. Macedo is included in SuperLawyers, IP Stars and Million Dollar Verdict.
