Sterling A. Brennan Attorney at Lawsbrennan@mabr.com949.202.1900


Sterling Brennan focuses on business and intellectual property litigation. He handles a broad range of litigation matters involving patents, trademarks, copyrights, trade secrets, securities, antitrust, unfair business practices, contracts, mergers and acquisitions, insurance coverage, and environmental claims. He has represented some of the country’s largest companies involved in the software and computer components, financial products and services, biotechnology, health services, energy, real estate, and petroleum industries.

Sterling’s representation extends to trials, arbitrations, and mediations. He has tried cases and handled appeals in federal and state courts, and is admitted to practice in all state and federal courts in California and Utah, as well as before the Ninth, Tenth, and Federal Circuit Courts of Appeal and the United States Supreme Court.

Sterling is the former chairman of the Business Litigation Section of the Orange County Bar Association and is the past chair of the Orange County J. Reuben Clark Law Society. In 2012, he was recognized by California Lawyer as one of the intellectual property lawyers of the year for his successful trial work on behalf of Novell in defending its copyright ownership of the Unix operating system.

Following graduation from law school, Sterling was a law clerk to a federal district judge in Los Angeles, and then joined the international law firm of Morrison & Foerster, where he was a litigation partner until 2003, when he joined Workman Nydegger (a Utah-based intellectual property firm). In 2013, Sterling joined with others in forming Maschoff Brennan, where he continues his litigation practice.
