Patrick Ryan, Co-Chair of Bartko's Antitrust Group, handles cases throughout the United States involving a cross section of complex commercial litigation, antitrust, intellectual property, trade secrets, class action, false advertising, and constitutional matters. Over the last 20 years, Patrick has successfully litigated, on both the plaintiff and defense side, numerous matters for major corporate clients from a variety of industries, including manufacturing, automotive, software, healthcare, retail, biotech, and real estate. Patrick is a business-centric lawyer who believes that lawyers should share the risk and rewards with the their clients through alternative-fee approaches. Patrick can make the most complex concepts simple to understand for judges and juries, and he regularly solves complex problems for companies—both in and out of court—using creativity and imagination.

Patrick gets to know a client's business and finds a way to substantially mitigate litigation risk while at the same time helping the client improve its bottom line. Patrick is known for being an excellent crisis manager who has led collaborative teams of dozens of lawyers across multiple law firms to achieve success for an industry or a group of clients.

In Global Competition Review (3 July 2013), Paul Ortiz, then a senior in-house attorney at Cisco, said, “I have worked closely with Patrick Ryan on numerous complex litigation matters, including antitrust matters; he is creative, attentive, and brilliant. Patrick knows his clients’ business goals and always finds a way to achieve them whether through settlement or litigation victory.”

Most recently, Patrick obtained an $845 Million judgment for ASML in one of the largest trade secret victories in US history (see attached Daily Journal and The Recorder articles), resulting in the Bartko firm being ranked as Number 3 in the Top 100 Verdicts for 2018 - published by The National Law Journal (June, 2019) - and having the highest ranked intellectual property victory in the United States for 2018. See attached award from the National Law Journal.

Prior to joining the firm, Patrick was a Partner and Chairman of Jeffer, Mangels, Butler & Mitchell, LLP’s Antitrust Group in San Francisco. Before joining JMBM, he was a Partner in the commercial litigation and antitrust practice groups of two global law firms—Winston & Strawn LLP and Morgan, Lewis & Bockius LLP. Patrick led the client team that received the 2011 commercial litigation law firm of the year award from a major electronics manufacturing company. He has led joint-defense teams representing dozens of large manufacturing companies accused of antitrust violations, among other things. In 2013, Patrick joined the firm so that he could take on more affirmative claim work with fewer conflicts and be able to provide more flexible fee structures to clients.
