During law school, Mr. Glennon won the Berkeley Law Moot Court award for Best Oral Advocate, authored a winning civil rights brief filed in the United States Supreme Court, and successfully prosecuted misdemeanor crimes in federal court on behalf of the United States Attorney’s Office for the Northern District of California.

Mr. Glennon is also active in the firm’s pro bono program, having successfully represented many low-income inner-city tenants in landlord-tenant disputes, multiple transgender and Afghani refugees in asylum proceedings, and families at adoption hearings.

Following law school, Mr. Glennon served as a law clerk to Judge Gary A. Feess, United States District Judge for the Central District of California.

Mr. Glennon is the Chair of Complex Courts Committee, the immediate past chair of the Litigation Section of the Los Angeles County Bar Association, and he is a member of the Federal Bar Association, the Association of Business Trial Lawyers, and the Association of Southern California Defense Counsel.

Mr. Glennon’s achievements include:

  • Secured summary judgment on behalf of Oracle Corporation and its officers in a US$3 billion securities fraud class action arising from a missed earnings forecast. The judgement was later affirmed by the Ninth Circuit in a published, precedential decision.
  • Defended Wal-Mart Stores, Inc., Wal-Mart’s Mexican subsidiary, and its executives in a high-profile securities fraud class action filed in the US District Court for the Southern District of New York. Obtained a complete dismissal with prejudice of all claims against all defendants at the pleadings stage.
  • Defended LogMeIn and its senior executives in a string of high-profile securities class actions filed in federal and state court, as well as a shareholder derivative lawsuit, following LogMeIn’s US$1.8 billion acquisition of Citrix’s “GoTo” business. Obtained complete dismissals with prejudice of all lawsuits at the pleadings stage, earning Mr. Glennon recognition in American Lawyer’s Litigator of the Week publication.
  • Defended Insight Enterprises, Inc. and its officers and directors in a securities fraud class action and multiple derivative cases following Insight’s restatement announcement. Obtained dismissals with prejudice of all lawsuits at the pleadings stage. These dismissals were later affirmed on appeal.
  • Represented Avago in its high-profile US$37 billion acquisition of Broadcom (the largest such acquisition at the time). In the face of Avago's pending motion to dismiss, the shareholder plaintiffs agreed to dismiss all claims against Mr. Glennon's clients in a "disclosure only" settlement, and nominal attorney's fees.
  • Represented Hudson Pacific Properties and its Board in a shareholder lawsuit arising out of a US$3.5 billion acquisition. After defeating plaintiff’s emergency motion to enjoin the shareholder vote (a ruling that was named Verdict of the Year in 2015 by The Daily Journal), the plaintiff voluntarily dismissed the lawsuit against all defendants with prejudice.
  • Successfully represented the founder, former Chairman, and CEO of Banc of California in a securities class action and three shareholder derivative lawsuits arising out of a short-seller report which resulted in a stock drop. At the conclusion of fact discovery, the plaintiff dismissed the client with prejudice (with a full release, but no payment) and agreed to state in the dismissal papers that the key allegations made about the client lacked any proof. The plaintiffs in the three related shareholder derivative cases voluntarily dismissed their cases.
  • Represented a Big Four accounting firm against claims of professional malpractice in two confidential arbitrations in which the claimants alleged well more than US$1 billion in damages. Following a two week evidentiary hearing, but before any award was rendered, the claimant agreed to settle the case and dismiss all claims for a nominal settlement payment.
  • Represented KPMG LLP in a shareholder derivative lawsuit alleging claims of professional malpractice and aiding and abetting breaches of fiduciary duty in connection with its audits of a technology company accused of stock option backdating. Achieved a complete dismissal with prejudice at the pleadings stage.
  • Represented the former CEO of Wilshire State Bank in a securities fraud class action and related derivative cases following the bank’s disclosure of a material adjustment to earnings. Obtained dismissals with prejudice of all lawsuits. The decision was featured by The Daily Journal.
  • Defended the company and individual defendants in a complex commercial litigation jury trial involving alleged damages in excess of US$100 million. Following four weeks of trial, the jury returned a complete defense verdict after deliberating for less than 24 hours.
  • Represented minority shareholders in a shareholder derivative lawsuit which ultimately culminated in a hearing before an en banc panel of the Nevada Supreme Court. Mr. Glennon successfully argued the appeal and obtained a reversal of the lower court's decision in a landmark opinion in which the State of Nevada adopted Delaware’s standards for pleading demand futility.
  • Represented World Oil Corp. and its affiliated companies in shareholder litigation involving derivative claims, individual claims for substantial damages, and dissolution. Prevailed on more than a dozen motions before the shareholder plaintiffs agreed to settle all claims on favorable terms, resolving all claims against the company and the individual defendants.
  • Defended the former CFO of a publicly traded company in a securities fraud class action involving allegations that defendants engaged in an alleged scheme to inflate stock prices through “stock-loan” transactions. Obtained a dismissal with prejudice of all claims at the pleadings stage.
  • Represented Deloitte & Touche in a securities fraud class action stemming from the New York Attorney General’s investigation into alleged “bid-rigging” and “steering” practices in the insurance industry. Obtained a dismissal with prejudice of all claims at the pleadings stage.
