Josh has litigated in a variety of complex matters on behalf of clients throughout the United States and in Europe. He has advised clients in the finance, art, entertainment and media, start-up and emerging technology, online retail, biopharmaceutical, real estate, construction, chemicals, and automotive industries. In 2012, Josh successfully argued the landmark case Cariou v. Prince in the U.S. Court of Appeals for the Second Circuit on behalf of the appropriation artist Richard Prince. The Second Circuit ruled that 25 of the 30 Prince works at issue were protected as fair use and remanded the remaining five works to the District Court for further determination. The U.S. Supreme Court declined to review the Second Circuit ruling.
