Ron Coleman is a Member of the Firm’s Intellectual Property and Commercial and Corporate Litigation Practice Groups. He is a commercial litigator focusing on torts of competition who has shaped the law relating to the use and abuse of intellectual property as a tool of competition and free speech in the last two decades. An experienced first-chair litigator and appellate advocate, he has also been recognized for his pioneering use of social media in his legal role.

His blog about copyright, trademark and free speech, LIKELIHOOD OF CONFUSION®, has since its inception in 2005 become one of the most influential publications in IP law.


Ron has tried innumerable cases to verdicts in jury and bench trials in the U.S. District of New Jersey, the Southern and Eastern Districts of New York, the District of Arizona and the Superior Court of New Jersey and has successfully resolved cases on dispositive motions in federal district courts in California, Nevada, Utah, Pennsylvania, Florida, Maryland and in the state courts in New York and New Jersey. He has also argued appeals before the U.S. circuit courts in the Second, Third, Ninth and Federal Circuits, Trademark Trial and Appeals Board of the Patent and Trademark Office and the appellate divisions in both New York and New Jersey. 

Ron was co-author of the chapter on “Responses to Complaints” in Business and Commercial Litigation in the Federal Courts (ABA / West Group 1998) and wrote the first article on Internet law in the ABA Journal (1995). He was also principal co-author of a New York City Bar Association report, “Online Auction Sites and Trademark Infringement Liability,” that has been cited extensively in academic treatments of the issue of online trademark infringement liability. Ron has presented on copyright and trademark law at virtually every major intellectual property organization and at the invitation of bar associations and IP groups across the U.S. His 2016 article on the use of social media evidence in proving trademark rights in the The Trademark Reporter, the peer-reviewed journal of the International Trademark Association, was cited approvingly in a judicial opinion within a year of its publication.

A graduate of Princeton University and Northwestern University School of Law, Ron was named a leader in the field of intellectual property law and profiled in the World Intellectual Property Review’s (WIPR) 2017 Leaders Directory and a World Trademark Review “WTR 1000 Top Practitioner” for trademark litigation in New York City the last two years, and has been listed in the “Super Lawyer” directory for intellectual property litigation in New York City since 2012. In 2017 he was named a “Distinguished Leader” by the New Jersey Law Journal in recognition of his accomplishments and demonstrated leadership skills within the legal industry and business community.

His recent representations include:

  • Leading the effort – from Patent and Trademark Office proceedings through oral argument before the U.S Court of Appeals for the Federal Circuit and, ultimately, appearing before the U.S. Supreme Court – to overturn the PTO’s refusal to register the trademark THE SLANTS to Asian American band leader Simon Tam. In June 2017 the Supreme Court unanimously ruled in Mr. Tam’s favor, finding viewpoint-based restrictions on trademark registration unconstitutional under the First Amendment.
  • Preparing and arguing the successful opposition to a motion brought by one of the world’s largest pharmaceutical companies to dismiss a competitor’s counterclaims for trademark infringement, Sherman Act monopolization and other torts of competition in the Eastern District of Virginia
  • Leading the litigation team, as first chair in injunction and dispositive motion proceedings in federal courts throughout the country that vindicated the rights of review websites threatened with IP infringement claims meant to intimidate them into removing legally protected information or commentary.  Ron’s aggressive defense against these claims helped set the standards nationwide for protection of such activities under both trademark law and the Section 230 of the Communications Decency Act
