Umberg/Zipser LLP is a premier business litigation and intellectual property boutique law firm. Drawing on decades of experience in some of the nation’s largest and most prestigious law firms, as well as national and state government service, our lawyers are recognized for providing exceptional legal work product and service. We have the ability to meet our clients’ unique needs by offering a range of flexible billing arrangements that promote efficiency and predictability.

We bring our ingenuity and creativity to every engagement, and work with the utmost integrity. If trial is necessary, we have the skills to put our clients in the best possible position to win, and the track record to prove it. We also employ effective pretrial strategies, successful motion practice, and alternative dispute resolution to achieve superb results without a trial, or even without the need to file a lawsuit. Our intellectual property team has the expertise and experience to develop, and protect, our clients’ valuable patent, trademark, and other IP rights.    

Umberg/Zipser has repeatedly been recognized for its outstanding service and quality. We are proud to have been named one of the Daily Journal’s Top Litigation Boutique Firms, and our lawyers are consistently recognized as among the very best in their fields, including by Best Lawyers in America® and Super Lawyers®. One of our founding partners was named “Lawyer of the Year” by Best Lawyers in America® for Bet-The-Company Litigation and Intellectual Property Litigation in Orange County.    

In addition to our focus on superior service and work quality, one of our core values is giving back. Umberg/Zipser has an unmatched commitment to the Orange County community, and to our profession. We regularly handle pro bono matters for people who cannot afford an attorney, and our attorneys devote countless hours to professional, community, and charitable service. Our team includes current and former presidents of organizations such as the Orange County Bar Association, the Federal Bar Association of Orange County, the Association of Business Trial Lawyers (Orange County), and the Constitutional Rights Foundation of Orange County. One of our founding partners currently is serving as a California State Senator and previously served in the California State Assembly, as well as key positions in the federal government. 

We also proudly celebrate the diversity in our professionals and staff. We hail from many countries, and speak several languages, including Mandarin, Cantonese, Spanish, German, Hindi, and Farsi. We believe our diversity adds to our strength.
