Michael focuses on all areas of intellectual property law, harnessing his electrical engineering background to help businesses reap maximum value from their innovations.

As a Partner in the firm's Intellectual Property Practice Group, Michael develops effective offensive and defensive patent strategies for organizations of all sizes. He has negotiated, defended, and asserted IP rights in federal courts, the U. S. Patent and Trademark Office, the International Trade Commission, and private arbitrations and mediations. As an advisor, he has worked with both established companies and startups to obtain, value, license, and develop patent portfolios and trademarks.

Trained in electrical engineering and having a business background as a technology consultant, Michael is known for his ability to quickly learn new technologies and distill complicated topics. He 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.

Michael was listed in the 2017 edition of IAM Strategy 300 – The World's Leading IP Strategists and has regularly been listed in Super Lawyers. Clients describe him as creative, energetic, and easy to work with and seek his insight into the business, technology, and legal facets of their IP issues.

Michael has defended and resolved scores of patent infringement lawsuits, resulting in successful motions to dismiss, summary judgment, and favorable settlements, in all of the key patent infringement venues, including the District of Delaware, the Eastern District of Texas, the Northern District of California, and the Northern District of Illinois. For example, Michael recently

  • Spearheaded key arguments in a patent-defense case for JVC, winning favorable ITC decisions and securing early settlements for numerous defendants.
  • Vindicated Panasonic in a jury verdict that was central to a semiconductor patent war with Samsung.
  • Helped invalidate key patents held by VirnetX, which had previously won verdicts in the hundreds of millions of dollars from industry giants such as Apple.

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.

In 2008– 2009, he was seconded to Panasonic Corporation in Japan. As in-house patent counsel in the company's licensing center, he acted as lead counsel representing the company in litigation, third-party patent assertions, license negotiations, portfolio cross-license agreements, and strategy.

Michael writes and speaks extensively. His articles have appeared in LEXIS, Practical Law Company, IP LAW 360, Bloomberg/BNA, Managing IP Magazine, and elsewhere. Michael is the sole author of Practical Law Company's Practice Note on Patent Law and the Lexis Practice Advisor on Patent Licensing and is a co-author of Practical Law Company's Practice Notes on Global Patent Litigation and Licensing and on 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). He also has assumed leadership positions in the IP bar. He heads the New York Chapter of the International Intellectual Property Commercialization Council (IIPCC), is the Co-chair of the Media Committee for the New York IP Lawyers Bar Association (NYIPLA), and serves as a member of the Legislative Action Committee.

A member of the Firm's Diversity Committee, Michael has been the keynote speaker at conferences addressing topics such as diversity and mentorship. Michael is also an adjunct professor at his alma mater, NYU, as well as at New York Law School. He has guest lectured at the NYU Business and Law Clinic, the NYU School of Medicine, New York Law School, and Seton Hall Law School.

He has appeared 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 publications such as The Huffington Post, Salon, The BBC, The Daily Dot, Money, and Redbook. Recently, he was interviewed on CNBC's public television show Nightly Business Report regarding the Maps features of Snapchat and their privacy implications.

Michael received his J.D. magna cum laude from New York University School of Law. He was a member of the NYU Law Review and the Order of the Coif, 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. After law school, he clerked for the Honorable Judge Roderick R. McKelvie in the U. S. District Court for the District of Delaware. Michael received a B.S.E. in electrical engineering magna cum laude from the University of Pennsylvania. He was a member of Eta Kappa Nu, Tau Beta Pi, and the Penn Parliamentary Debate Team.
