Mr. Liversidge’s representative matters include:

• Representation of Hewlett-Packard Company in Hewlett-Packard Co. v. Oracle Corporation (Santa Clara Superior Court, California), where HP brought suit against Oracle for breach of contract and unfair competition following Oracle’s decision in March 2011 to cease offering new versions of its software products to customers running HP’s mission-critical Itanium servers. Following a five-week jury trial in 2016, the jury found in favor of HP on all claims tried and awarded HP over $3 billion in damages, the largest jury verdict reported in 2016.
• Representation of Merck & Co., Inc. in In re Zetia (Ezetimibe) Antitrust Litigation (E.D. Va.), where plaintiffs allege an unlawful agreement and conspiracy to delay generic competition (ongoing).
• Representation of Chevron U.S.A. in antitrust class actions filed in the Southern District of California alleging a conspiracy to reduce supply and inflate gasoline prices (ongoing).
• Representation of Intel Corporation in a monopolization suit filed by Advanced Micro Devices (“AMD”) in the U.S. District Court in Delaware. AMD alleged that Intel monopolized a worldwide market for microprocessors through purportedly unfair discounting and rebating practices. Characterized as one of the largest, if not the largest, Sherman Act Section 2 cases ever filed, the parties reached a global settlement in November 2009 to end all outstanding litigation, including AMD’s antitrust suit, two claims pending in Japan, and cross-license disputes.
• Representation of Aetna in Bay Area Surgical Management et al. v. Aetna Life Insurance Company et al. (Norther District of California), where plaintiffs brought antitrust claims alleging an unlawful conspiracy to retrain trade in the healthcare market. The case was successfully settled following the court’s grant of defendants’ motion to dismiss.
• Representation of Dole Food Co. in In re: Fresh and Process Potatoes Antitrust Litigation (District of Idaho), where several class action complaints were filed on behalf of direct and indirect purchasers against Dole and 19 other defendants alleging a conspiracy to restrict the supply and raise the price of fresh and process potatoes, in violation of Section 1 of the Sherman Act and various state laws. On December 2, 2011, the U.S. District Court for the District of Idaho granted Dole’s motion to dismiss in full and with prejudice, dismissing Dole from the case.
• Representation of Hewlett-Packard Company in Wilson v. Hewlett-Packard Co. (Northern District of California), where plaintiffs asserted a nationwide class action under California’s Unfair Competition Law (17200) and Consumers Legal Remedies Act arising out of HP’s alleged failure to disclose a defective connection between the power jack and motherboard in over 12 million notebook computers, which allegedly caused a safety risk. A complete dismissal of the case was achieved at the pleading stage. In a published decision issued on February 16, 2012, a unanimous panel of the Ninth Circuit affirmed the dismissal. The Ninth Circuit held that plaintiffs’ allegations regarding the safety concerns and HP’s knowledge were not sufficient to plausibly demonstrate that HP intentionally concealed an unreasonable product hazard.
• Representation of VFM Leonardo, Inc. in Pro Search Plus v. VFM Leonardo (Central District of California), where plaintiff has asserted that VFM Leonardo violated Sections 1 and 2 of the Sherman Act by entering into a series of allegedly “exclusive” contracts with hotels, online travel sites and other intermediaries, and by allegedly threatening potential and actual customers.   The matter was successfully settled.
• Representation of Hewlett-Packard Company in Zwart v. Hewlett-Packard Co. (Northern District of California), where plaintiffs asserted a nationwide consumer class action under California’s Consumers Legal Remedies Act and Unfair Competition Law based on HP’s alleged fraud and deception in connection with the sale of its notebook computers. The lawsuit, filed by two individuals who had purchased HP computers at retail, alleged that the Hewlett-Packard’s website contained false representations about the capabilities of wireless cards installed in HP laptops. The plaintiffs also alleged that HP breached a warranty by description created by the website statements the plaintiffs identified.   On August 23, 2011, the district court granted HP’s motion to dismiss the case in full and with prejudice.   The court held that the plaintiffs lacked standing to bring the asserted claims and were unable to establish either reliance or the existence of a warranty by description.
• Representation of Hewlett-Packard Company in Kowalsky v. Hewlett-Packard Co. (Northern District of California), where plaintiffs brought a nationwide consumer class action asserting violations of California’s Consumers Legal Remedies Act, Unfair Competition Law, and False Advertising Law based on HP’s alleged false and deceptive statements in connection with the sale of its 8500 series inkjet printers. On March 15, 2012, following extensive briefing, the district court denied plaintiffs’ motion for certification of a nationwide class of consumers, and the case subsequently settled.
• Representation of Hewlett-Packard Company in Baba v. Hewlett-Packard Co. (Northern District of California), where plaintiffs have asserted a nationwide consumer class action under California’s Unfair Competition Law, Consumers Legal Remedies Act, and various state warranty laws, arising out of HP’s alleged failure to disclose a defect in certain tablet notebooks.
