Joel G. MacMull is a Partner and Co-Chair of the Firm’s Intellectual Property & Brand Management and Commercial and Corporate Litigation Practice Groups. Joel’s practice focuses on high-stakes complex commercial litigation and intellectual property disputes, including copyright and trademark infringement, trade secret misappropriation, false advertising, “cybersquatting,” rights of publicity, as well as general contract and business tort disputes. Joel has tried and argued cases in state and federal courts, as well as before the Trademark Trial and Appeal Board.

Joel also has significant appellate experience. He was intimately involved in the U.S. Supreme Court’s recent landmark decision in Matal v. Tam (formerly Lee v. Tam), in which the Supreme Court by a unanimous vote of 8-to-0 (Justice Neil Gorsuch did not participate in the consideration or decision of the case) affirmed the Court of Appeals for the Federal Circuit ruling in late 2015. The High Court held that § 2(a) of the federal trademark statute violates the free speech clause of the First Amendment because the government discriminates based on viewpoint and targets offensive expression with an intent to discourage its use.

Joel has also briefed and argued multiple cases before the Second Circuit, and the New York Appellate Division.

  • Roca Labs, Inc. v. Consumer Opinion Corp. et al., (United States District Court for the Middle District of Florida). Represented interactive computer service provider against nutraceutical weight loss manufacturer’s claims of, among other things, tortuous interference because defendants knowingly maintained negative posts on their website in violation of a “gag clause” appearing in plaintiff’s sales contracts with its customers. In response, the Court recently issued a resounding dismissal of each of plaintiff’s twelve claims, finding that all of them were barred under section 230 of the Communications Decency Act of 1996, 47 U.S.C. § 230.
  • Whitestone Construction Corp. v. Nova Casualty Co., et al., (Supreme Court of the State of New York, Appellate Division). Represented general contractor in connection with a breach of contract claim against a sub-contractor and its various alter egos.
