Firm History

Frommer Lawrence & Haug LLP was formed in 1997 in New York City by seven partners that had been practicing together for many years at a 75-year old IP firm. Beginning with 17 lawyers, FLH quickly grew its ranks and clientele and now has about 70 lawyers with diverse technical backgrounds that can handle matters in the electronic, pharmaceutical, life sciences, and other technical fields. FLH has expanded beyond New York City with the opening of its Washington D.C. office in 2006.  From the outset, FLH has delivered value to its domestic and international clientele handling complex patent litigations throughout the United States and large international patent prosecution dockets. FLH maintains a core IP practice in the traditional areas of patents, trademarks, copyrights, and unfair competition. The firm’s FDA, antitrust and licensing practices complement FLH’s well-recognized patent litigation practice, especially in the pharmaceutical industry, where the firm has successfully handled hundreds of patent cases.

Pro Bono

FLH has an outstanding track record of providing pro bono representation for individuals in need. Through a dedicated program encouraging 100% attorney participation, FLH logs thousands of hours every year in pro bono service. Cases handled by FLH attorneys on a pro bono basis include veterans’ appeals before the Court of Appeals for the Federal Circuit and the representation of pro se litigants at all levels in the federal court system. In this capacity, FLH has helped numerous veterans pursue benefits from the U.S. Government for unpaid medical bills and unpaid disability benefits. FLH has also represented federal prisoners who allege human rights violations in connection with their incarceration. In a case that went all the way to the U.S. Supreme Court, FLH represented a farmer pro bono who was sued by Monsanto for patent infringement when the farmer planted seed he purchased on the open market from a local grain elevator. In addition to litigation, FLH attorneys also provide pro bono assistance in patent and trademark prosecution matters for financially under-resourced businesses, nonprofit organizations, and independent inventors.
