David has a wide range of life experiences he brings to bear in assisting his clients.  Beginning in high school, he spent summers working with a rural mass immunization program in South America, in the process negotiating with national government officials, priests, mayors, superintendents of public schools, airlines, and others.  As a college student, David—an Arizonan—was elected to represent Massachusetts at a Democratic National Convention.  While still in law school, David obtained the first two of several precedential opinions in copyright law, one of which has been cited by the Supreme Court and virtually every circuit court of appeals.  See Quinto v. Legal Times of Washington, Inc., 506 F. Supp. 554 and 511 F. Supp 579 (D.D.C. 1981).

After graduating from Amherst College cum laude, spending a year as a Rotary graduate fellow at the University of Hong Kong Faculty of Law, and earning his J.D. degree from Harvard Law School, David began practicing law with Paul Hastings Janofsky & Walker.  In January 1986, he joined three other lawyers in founding what is now the worldwide litigation powerhouse, Quinn Emanuel Urquhart & Sullivan, LLP.  While a partner there, David performed much of the outside legal work for the Academy of Motion Picture Arts and Sciences for 27 years (and claims as his lifetime dubious achievement having attended 25 ©Oscar® ceremonies), represented the Lockheed Martin Skunkworks® in trade secret cases, and prevailed on behalf of Mattel in an action before then District Judge Sonia Sotomayor.  David then joined a former Quinn Emanuel partner in starting their own firm before being persuaded to go inhouse as the Chief Legal Officer of VidAngel, Inc. in 2016, remaining there for more than three years.  Upon leaving, he became of counsel to One LLP after being socially acquainted with its professionals for years.

In an effort to share what he has learned during his career, David authored an early treatise on Internet tort law, three editions of which were published by Aspen Law & Business entitled Law of Internet Disputes.  After defending his client in a trade secret misappropriation case in which the parties collectively incurred tens of millions in attorneys’ fees before the plaintiff accepted that no misappropriation was ever intended or had occurred, David was inspired to write a national practitioner’s guide to all things trade secret.  Joined by his classmate and former Harvard Law Review president Stuart Singer, David co-authored Trade Secrets: Law and Practice, published initially by Oxford University Press.  Following the publication of the third edition, LexisNexis acquired the rights to their book.  New editions are published annually in hardcover and online.  Joined by Quinn Emanuel partner Anthony Alden, David also co-authored a chapter of Trade Marks at the Limit, published by Edward Elgar Publishing.

David has served as a World Intellectual Property Organization (“WIPO”) Uniform Domain Name Dispute Resolution Panelist (“UDRP”) since 2004, been voted a Southern California Super Lawyer every year the honor has been conferred, been selected as a Hollywood Reporter “Top 100 Power Lawyer,” been named as a Top Rated Lawyer in Intellectual Property by American Lawyer Media and Martindale-Hubbell, and been honored as a member of the “Lawdragon 500 Leading Lawyers in America.”   He is admitted to practice in Arizona and California, the Second, Ninth, and Eleventh Circuit Courts of Appeals, and all district courts in California, Arizona, and Colorado.  David is widely traveled, having visited more than 140 countries, camped within 650 miles of the North Pole, and spent Christmas in Antarctica.  When not on the move or at the desk, David is an avid gardener and beekeeper.
