Michael is a partner in the firm's Intellectual Property Practice and is a member of the Diversity Committee. He has negotiated, defended and asserted IP rights in the numerous federal courts, the US Patent and Trademark Office, the International Trade Commission and in private arbitrations and mediations. As an advisor, he has worked with both established companies and start-ups to obtain, evaluate value, license and develop patent portfolios and trademarks.

Trained in electrical engineering and with a business background as a technology consultant, Michael works with a broad range of technologies, including consumer electronics, wireless devices, batteries, mechanical devices, medical products and devices, computer architecture, software and networks, including open source software semiconductor chips and Internet and e-commerce platforms.

His clients rely on him to resolve both large and small patent, trademark, and copyright cases efficiently and cost-effectively. For example:

  • In a fast-moving ITC case on behalf of JVC Corporation, he spearheaded the two key claim construction issues for the joint defense group. The Administrative Law Judge took the unusual step of agreeing to stage the claim construction phase on potentially dispositive terms early in the case. The success in getting the Court to agree to an early claim construction phase drove favorable early settlements for numerous defendants.
  • In a competitor semiconductor case brought by Samsung against Panasonic Corporation as part of a global patent war involving the major electronics companies, he was instrumental in the defense of patent infringement claims and helped to obtain a jury verdict of non-infringement for his client.
  • Michael was involved in the successful defense of a series of competitor patent infringement lawsuits brought by Kimberly-Clark against First Quality, asserting infringement of mechanical processes, inspection processes and the materials structure of diaper and training pants products.
  • Michael was involved in leading a series of IPRs that successfully invalidated key patents held by VirnetX, which had previously won verdicts in the hundreds of millions of dollars from industry giants such as Apple and others.
  • He has defended and resolved scores of patent infringement lawsuits, achieving success on motions to dismiss, summary judgment, and in positioning defenses to leverage favorable settlements, in all of the key patent infringement venues, including the District of Delaware, the Eastern District of Texas, the N.D. of California, and the N.D. of Illinois.

Michael also counsels clients on strategic patent prosecution and portfolio development, and provides opinions and analyses on various patent issues, including patent infringement, validity and enforceability.

During 2008-2009, he was seconded to Panasonic Corporation in Japan. As in-house patent counsel in Panasonic's licensing center, he acted as lead counsel representing the company in numerous third-party patent assertions and license negotiations, where he was responsible for developing substantive defensive positions. Michael also provided legal opinions across a broad set of technology areas and in many facets of patent law, and negotiated complex agreements, including portfolio cross-license agreements. In addition, he worked with the company's managers and engineers to identify high value patents and to strengthen their protection and mitigate exposure to infringement claims.

Michael frequently writes and speaks on a range of topics including IP litigation in District Courts and in the ITC, standard essential patents, patent monetization, valuation, and licensing practices, how to address IP issues for start-up and early stage companies, patent eligibility, patent exhaustion, willful infringement, patent misuse, patent valuation and inequitable conduct, data security and privacy. His articles have been published in leading publications, including LEXIS, Practical Law Company, IP LAW 360, Bloomberg/BNA, and Managing IP Magazine. Michael is the sole author of Practical Law Company's Practice Note on Patent Law and the Lexis Practice Advisor on Patent Licensing and a co-author of its Practice Notes on Global Patent Litigation and Licensing and Tracking and Privacy. He is the author of the chapter on Patent Licensing and Monetization of the Oxford Handbook of Intellectual Property Law (Oxford Press, 2017). Michael has also been the keynote speaker at conferences addressing topics such as diversity and mentorship. Michael also teaches as an adjunct professor at his alma mater, NYU, as well as at New York Law School, addressing topics such as IP licensing, global patent litigation, patent exhaustion, and inequitable conduct. He has also guest lectured at the NYU Business and Law Clinic, the NYU School of Medicine, and at New York Law School and Seton Hall Law School. He clerked for the Honorable Judge Roderick R. McKelvie in the United States District Court for the District of Delaware.

Michael received his J.D. magna cum laude, from New York University School of Law. He was a member the NYU Law Review, the Order of The Coif, and was Fish & Neave Fellow for the Engelberg Center on Innovation Law and Policy, and served as President of the Intellectual Property and Entertainment Law Society.

He heads the New York Chapter of the International Intellectual Property Commercialization Council (IIPCC). Michael also is the Co-Chair of the Media Committee for the NYIPLA (NY IP Lawyers Bar Association) and serves as a member of the Legislative Action Committee.

Michael also received a B.S.E. in Electrical Engineering, magna cum laude, from the University of Pennsylvania. He was a member of Eta Kappa Nu and Tau Beta Pi, Engineering Honor Societies, and a member of Penn Parliamentary Debate Team.

Outside of work, Michael serves as the Director of Communications and Development of the non-profit MyChild'sCancer. He also serves on the Board of the SouthNextFestival. He was formerly the Chairman of the Board of the non-profit CityScience, which focuses on improving STEM Education in our cities. He is also a contributor for The Good Men Project. He has spoken on a variety of issues on major media networks, including CNN, CNN Headline News, Al Jazeera America, NPR, CBS News Radio, and CBC Radio, and his writings have appeared in well-known publications such as The Huffington Post, Salon, The BBC, The Daily Dot, Money and Redbook. Recently, he was interviewed on CNBC's public television Nightly Business Report regarding the Maps features of Snapchat and its privacy implications.
