Gregory P. Stone, a partner in the Los Angeles office of Munger, Tolles & Olson, is widely recognized for his trial skills, particularly in patent, antitrust and unfair competition cases. He also specializes in defending, and trying, class actions, including product liability, toxic tort and antitrust class actions.

Mr. Stone is fellow of the American College of Trial Lawyers. He is consistently ranked by Chambers USA as a leading lawyer and was named by the Daily Journal as one of the Top 100 lawyers in California. He has also been repeatedly recognized by the Daily Journal as one of the Top Intellectual Property Lawyers in California. The Daily Journal reported that he obtained the largest plaintiffs’ verdict in California in 2006 and one of the top 10 defense verdicts in California in 2008. Mr. Stone was also recognized as an Attorney of the Year by The Recorder in 2010.

Mr. Stone has represented companies whose business interests span a wide spectrum, from technology companies like Microsoft, Cisco, HP, Genentech, Rambus, and Tessera, to manufacturing and consumer product companies like Philip Morris USA, Verizon Wireless, and Safeway Stores. He also has represented a number of smaller companies in various areas of emerging technology, including companies developing new software products, new designs of solar panels, and new RFID devices.

His expertise in intellectual property and antitrust law has led him to handle many matters that lie at the intersection of those two fields of law. For instance, he was lead trial counsel for Rambus in a three-month long trial brought by the FTC charging Rambus with antitrust violations as the result of its efforts to obtain and later assert patents covering fundamental technologies and designs that are used in the memory chips found in nearly every computing device sold today, including computers, cell phones and HDTVs to name just a few.

After successfully defending Rambus at the trial and surviving several rounds of appeals, Mr. Stone succeeded in having all of the FTC’s claims dismissed. He also has developed significant expertise in California’s Unfair Competition Law, particularly in the context of class actions, and served as lead counsel in In re Tobacco Cases II, one of the most significant UCL cases of the past few decades.
