Orange County

In November 2014, Haynes and Boone’s Orange County office relocated to Plaza Tower in Costa Mesa, demonstrating our dedication to the continued growth in California and around the world. Catering to the needs of California’s premier technology industries and taking advantage of the West Coast’s global access, Haynes and Boone’s Orange County office has a strong focus on intellectual property, technology transactions, corporate law, commercial litigation, labor and employment and real estate law.

Orange County is first and foremost a center of industry. The thriving economic community is home to a wide array of businesses, ranging from Fortune 500 companies to emerging technology ventures. Our presence here heightens Haynes and Boone’s coast-to-coast capabilities while offering clients, particularly those doing business in California and Asia, the benefits of our expanded geographic base. Most of our California-based lawyers have earned engineering or technical degrees in addition to law degrees, enhancing their understanding of the intricacies of intellectual property.

With full-time IP lawyers nationwide, Haynes and Boone’s California offices are backed by the full resources of the firm. Multidisciplinary teams are available to address the opportunities California offers for many of our clients in intellectual property as well as areas including in-bound Asian work, venture-funded corporate matters, and big-ticket litigation such as patent, securities, insurance coverage, and class action labor and employment matters.
