David J. Lender

David’s multi-disciplinary practice encompasses matters involving patent, antitrust, consumer fraud, and contract issues, among others, including in the class action context. He has tried more than 30 cases to verdict as a first chair – many of which have resulted in his clients obtaining, or avoiding, hundreds of millions of dollars in damages.

David’s notable recent engagements include:

• Successfully representing ExxonMobil as lead trial counsel in winning a complete defense jury verdict following four days of trial in the Eastern District of New York, in a multi-million dollar breach of contract suit brought by BP seeking attorneys’ fees related to BP’s defense of nearly two dozen environmental contamination lawsuits.
• Successfully representing a major e-commerce company in a contract dispute relating to a multi-year operating agreement with a former business partner. Following a five-day arbitration and post-trial briefing, secured a complete victory and significant damages for the client.
• Successfully representing C&S Wholesale Grocers as lead trial counsel in securing a complete defense jury verdict in Minnesota federal court in an antitrust class action litigation with hundreds of millions of dollars at stake. After two weeks of trial, the jury rejected plaintiffs’ claim that C&S and Supervalu, another leading wholesaler based in the Midwest, entered into a conspiracy to allocate certain geographic markets in violation of the Sherman Act. Along with Weil partner Eric Hochstadt, David was recognized both as The American Lawyer’s “Litigators of the Week,” in which the publication characterized the rare, high-stakes case as “An Antitrust Unicorn – With $800M on the Line,” and as Global Competition Review’s “Litigators of the Week.” The Financial Times also recognized this victory as “Highly Commended” in the Dispute Resolution section of the publication’s 2018 “North American Innovative Lawyers” report. In 2020, following oral argument, the Eighth Circuit affirmed the verdict dismissing all claims.
• Winning the dismissal with prejudice of all claims brought against a leading coffee company in a consumer class action alleging violation of New York General Business Law sections 349 and 350 relating to alleged false representations and false advertising.
• Successfully representing General Electric in a multi-jurisdictional dispute with Japan-based Mitsubishi Heavy Industries Ltd. regarding wind turbine technology, including a $170 million jury verdict against MHI in a patent infringement litigation in Texas federal court – a significant victory that The Wall Street Journal called “closely watched in the estimated $12 billion U.S. market for wind energy equipment.” David was recognized as one of The American Lawyer’s “Litigators of the Week” for his role in obtaining this verdict.
• Serving as lead nationwide counsel for Credit Suisse and its affiliates in a series of multi-jurisdictional, multi-faceted disputes worth billions of dollars relating to syndicated real estate loans made to resort developments across the U.S. David secured a number of significant victories in these cases, including obtaining the summary judgment dismissal of all claims and defeating class certification in a $24 billion RICO class action in Idaho federal court, and sustaining the summary judgment victory in that case before the Ninth Circuit. He also won a separate, $70 million award on summary judgment in a related dispute with a hedge fund that invested in the loans.
• Representing GE’s healthcare division in a patent infringement action brought by a competitor, Hill-Rom, relating to hand-hygiene compliance monitoring systems for use in hospitals and healthcare facilities. Defeated Hill-Rom’s motion for a preliminary injunction, and ultimately secured a favorable global settlement resolving all claims.
• Serving as lead trial counsel for ExxonMobil in a number of disputes in state and federal courts relating to the use of MTBE as an additive in gasoline. The actions have been brought by various states, including Vermont and New Jersey, seeking to recover for alleged groundwater contamination at sites throughout those states.
• Successfully representing Dow Chemical in highly publicized, multi-jurisdictional litigation brought by Greenpeace, including obtaining the dismissal of a RICO case in Washington, DC federal court, and the dismissal, affirmed on appeal, of an invasion of privacy case in DC Superior Court and the DC Court of Appeals. Greenpeace alleged that Dow and other companies engaged in illegal surveillance and stole information about Greenpeace’s investigation of the companies’ conduct and alleged impact on the environment.

David’s other significant trial and litigation achievements include:

• Winning a complete defense jury verdict for ESPN in New York Supreme Court in a $231 million lawsuit brought by Modi Entertainment Network regarding the launch of the ESPN channel in India, a case requiring the application of both New York and Indian law.
• Securing a $417 million jury verdict for Exxon Mobil Corporation against Saudi Basic Industries Corporation, one of the largest petrochemical companies in the world, in Delaware Superior Court, where he asserted claims for breach of contract and usurpation under Saudi Arabian law.
• Serving as co-lead counsel for ESPN in a $1 billion defamation lawsuit brought by boxing promoter Don King, whom he deposed before obtaining summary judgment.
• Representing Sotheby’s in a number of litigations relating to its auctions, including winning a complete defense verdict involving a consignment of 17th-century New Mexican furniture and decorative arts.

David has played an instrumental role in protecting his clients’ valuable technology, much of which gears the ubiquitous products and daily transactions underpinning the economy today. In 2015, following oral argument before the Federal Circuit, David secured for Microsoft the affirmation of a lower court’s decision granting summary judgment of non-infringement and invalidity, a ruling that dismissed a patent infringement action relating to an invention that enables certain capabilities of speech recognition and word processing software. In 2012, David won a major appellate victory for StubHub before the North Carolina Court of Appeals, which, on an issue of first impression, ruled that StubHub was immune from liability under the federal Communications Decency Act for the unlawful price of concert tickets resold by third parties on its website – a decision of critical importance to Internet websites and the growth of e-commerce. In 2013, Financial Times highlighted David’s work on this and other matters in the “Lawyers to the Innovators” section of the publication’s annual “US Innovative Lawyers” report.

David is a recognized expert, author and frequent lecturer on electronic discovery issues. He is the co-author of the leading treatise on the subject, entitled Electronic Discovery: Law and Practice, originally published by Aspen Publishers in 2003, author of Privilege Issues in the Age of Electronic Discovery, originally published by BNA in 2008, and head of the Firm’s E-Discovery Task Force.

He is regularly recognized as a preeminent trial lawyer and litigator by leading industry publications. In 2020, The American Lawyer named David as a winner of its coveted “Litigator of the Year” award. Chambers USA identifies him among the Band 1-ranked commercial litigators in New York, where clients note he is a “phenomenal trial lawyer” and “a very accomplished litigator” with “excellent strategic sense,” “superb trial skills,” and “mastery of the details” and an ability to “think through the evidence and trial strategy with clarity and efficiency.” They also remark that he is a “powerhouse” who “gets the legal issues as well as the business issues,” is “able to synthesize and explain complex issues simply," “has an instinct for going for the jugular,” and “consistently delivers winning results at extremely efficient cost.” David has been recognized in the 2018-2024 editions of Benchmark Litigation as one of the Top 100 Trial Lawyers in America, and for many years by Legal 500, which describes him as a “brilliant litigator” and “outstanding in every way,” as among the top-ranked “Leading Lawyers” for general commercial litigation and trial lawyers nationwide. Since 2022, David also has been named in several Lawdragon 500 publications, including its 2024 and 2025 “Leading Litigators in America” lists, and its 2024 “ Leading Lawyers in America” list. The National Law Journal recognized him in 2018 as one of just 30 Litigation “Trailblazers” nationwide for his trial defense of “corporate defendants in their most significant disputes,” while BTI Consulting named him a Client Service All-Star. In 2012, Law360 recognized him as one of five “Class Action MVPs” nationwide, and in 2024 the same publication named him a “Trials MVP,” as well.
