Best Law FirmBest Law Firm 2016

BraunHagey & Borden LLP is a boutique firm that protects businesses, investors and entrepreneurs in high-stakes legal disputes in California, New York and around the country. We regularly defend clients in complex class actions, trade secrets, antitrust, intellectual property, unfair competition, employment, M&A, founders’ disputes, investment litigation and contested bankruptcy matters. 

Since our founding in 2009, we have secured ground-breaking judgments and settlements exceeding several billion dollars, including a highly publicized Top-100 national trial judgment. Our cases and results are regularly featured in industry press. We are one of the only litigation firms to have successfully dismissed and resolved over 40 class actions without a single class ever certified against a firm client. 

Our attorneys are seasoned litigators based in California and New York who graduated from top law schools and clerked for respected federal and state judges. Approximately one third of our active cases are venued in New York or Delaware. We relish litigating difficult, hard-to-win cases and have secured numerous victories against many of the so-called AmLaw "Top 25" law firms.

As part of our mission, we actively pursue pro bono and impact litigation where we can make a significant positive difference in the world. We have represented leading environmental and civil rights organizations across a wide array of issues. Our class-wide injunction on behalf of abused nursing home residents was featured in a TV news documentary that won an Emmy Award in 2015.


We are experienced commercial trial lawyers who have litigated the full range of disputes for businesses domestically and internationally. Our clients include publicly traded companies, tech startups, private equity funds, hedge funds, small businesses, entrepreneurs, executives and non-profits. Major cases we have resolved include disputes involving:
