Iian Jablon is a litigation partner in the Los Angeles office of Irell & Manella LLP, where his practice focuses on professional liability defense, securities litigation, business litigation, IP litigation, and white collar defense. He is also the firm's Co-General Counsel, a position he has held since 2010.

Mr. Jablon handles a broad range of complex litigation matters in both federal and state courts, and has extensive trial and arbitration experience in high-stakes matters, including first-chairing several trials. 

Representative civil cases:

  • Represented three nationally prominent law firms and several partners at those firms in numerous lawsuits alleging claims for breach of fiduciary duty and legal malpractice.
  • Represented the plaintiffs in a business dispute arising out of the termination and alleged squeeze-out of one of the founding members of a prominent investment management company. The matter settled on confidential terms shortly before trial.
  • Represented a husband and wife in a dispute with their former attorneys over the amount of the contingent fee those attorneys were entitled to for representing the clients in a long-running trust and estate litigation. The matter was tried in federal court in Dallas, and the former attorneys' fee claims were ultimately reduced by more than $25 million.
  • Represented Angelo Mozilo, former CEO of Countrywide Financial Corporation, in a lawsuit filed by the SEC alleging securities fraud and insider trading. A highly publicized settlement was reached with the SEC in the fall of 2010, shortly before the scheduled commencement of trial.
  • Represented Angelo Mozilo in a multi-defendant securities class action filed by several large pension funds. The parties reached a settlement while the defendants’ motions for summary judgment were pending. Mr. Jablon also represented Mr. Mozilo in several other civil matters between 2010 and 2015.
  • Represented the plaintiff, serving as lead trial counsel, in a complex, multi-party arbitration that included claims of alleged misappropriation of trade secrets, corporate espionage and breach of contract. The matter settled after three days of trial.
  • Represented the plaintiffs in an action in New York Supreme Court alleging misappropriation of trade secrets and interference with contract. The parties entered into a confidential settlement prior to trial.
  • Represented the plaintiff in federal court in New York relating to alleged breach of a securities purchase agreement, including an eight-figure damages claim. Mr. Jablon successfully moved to dismiss a cross-action filed by the defendant in Oklahoma, and the parties subsequently settled.
  • After a one-week arbitration, Mr. Jablon won a defense award in favor of his clients on all claims, including claims for fraud and negligent misrepresentation in connection with the sale of a business division. His clients also obtained a seven-figure attorneys’ fees award against the claimant.
  • After a seven-day trial, Mr. Jablon won a defense award in favor of his client on all claims, including claims for breach of fiduciary duty, breach of contract and other alleged misconduct. His client was also awarded attorneys’ fees.
  • Won a summary judgment for his client in this complex, multi-party probate court litigation involving alleged misuse of trust assets.
  • Won summary judgment for his client on claims for tortious interference and unfair competition and then obtained a published affirmance from the Federal Circuit.

Representative criminal cases:

  • Represented a prominent Texas businessman accused of making false statements in connection with a loan application. Mr. Jablon's work on the matter contributed to the criminal charges against the client being dismissed by the trial court.
  • Represented the prominent owner of a large private machine tool company who was accused of a multimillion-dollar tax fraud and conspiracy.
  • Represented a former executive vice president of Homestore Inc. who was accused of securities fraud and insider trading.
  • Represented a former CEO of a publicly traded technology company who was accused of multiple counts of securities fraud, wire fraud and money laundering.
  • After a lengthy trial, Mr. Jablon won an acquittal for his client (a tax attorney) on all five counts of tax evasion and conspiracy to evade taxes.

Mr. Jablon has also represented clients (both plaintiffs and defendants) in cases involving patents, business contracts, valuations, securities, real estate, corporate governance disputes, waste of corporate assets, bankruptcy, employment issues, and numerous other matters. He has also represented clients in connection with several complex class actions.  

Mr. Jablon received his J.D. in 1999 from the University of Southern California Law School, where he graduated first in his class. While at USC, Mr. Jablon served as a notes editor for the Southern California Law Review, was elected to the honor societies of Order of the Coif and Phi Kappa Phi, and received the Law Alumni, Alfred J. Mellenthin, and Gerald G. & Sally D. Kelly awards for academic excellence.
