Representative Experience:

  • Defended dental-implant manufacturer in complaint alleging class claims for declaratory relief, implied indemnity, breach of express and warranty, and a violation of California Unfair Competition Law, California Business and Professions Code §§ 17200, et seq. Drafted opposition to class counsel’s motion for attorney’s fees and then successfully appealed district court’s order awarding attorney’s fees. Drafted the appellate argument that was adopted in a precedential opinion by the Ninth Circuit that the district court's use over the defendants' objection of ex parte, in camera submissions to support its attorneys' fee order violated the defendants' due process rights because an opposing party was entitled to see what attorneys' fees were charged and why, and judicial efficiency could not eclipse the defendants' fundamental right to inspect and challenge these documents. Yamada v. Nobel Biocare Holding AG, 825 F.3d 536 (9th Cir. 2016).
  • Court granted motion for summary judgment of class action complaint alleging numerous warranty claims, products liability, and consumer fraud claims. Elsayed v. Maserati N. Am., Inc., No. SACV1600918CJCDFMX, --- F.Supp.3d ----, 2016 U.S. Dist. LEXIS 144238, 2016 WL 6091109 (C.D. Cal. Oct. 18, 2016). Case involved a remote keyless entry system in certain vehicles that plaintiffs alleged has dangerous defect that can lead to children being locked inside. “The 10 causes of action allege that the [passive entry system’s] failure to unlock the car in these circumstances breaches express warranties, constitutes negligent design and failure to warn, violates implied warranties and violates the California’s Consumers Legal Remedies Act and Unfair Competition law,“ the judge said. “None of these causes of action survive summary judgment,” the court found because the vehicle performed as the automaker said it would in its owner’s manual and other written materials.
  • Court granted Federal Rule of Civil Procedure 12(b)(1) motion to dismiss that made a factual challenge to plaintiff’s standing to sue under Article III of the U.S. Constitution in a data breach class action alleging claims for negligence and violations of California’s Unfair Competition Law, Cal. Bus. & Prof. Code § 17200; Consumers Legal Remedies Act, Cal. Civ. Code § 1750; and Customer Records Act, Cal. Civ. Code § 1798.80. Demonstrated that the claimed stolen credit card information from a data breach was never collected and that plaintiff’s personal information was never stored on the breached internal-computer system. The court ruled plaintiffs’ allegation that cybercriminals obtained plaintiffs’ personal information through the breach was “factually impossible” and dismissed with prejudice. Foster v. Essex Property Inc., No. 5:14-cv-05531-EJD, 2017 U.S. Dist. LEXIS 8373, 2017 WL 264390 (N.D. Cal. Jan. 20, 2017).
  • Secured dismissal of a rabbinical council that certifies foods as glatt kosher from a consumer-protection class action based on a demurrer raising novel First Amendment issues.
  • Defended a major American footwear company in connection with claims by approximately 740 consumers who claim to have been injured as a result of what they allege are design defects in the footwear, and settled claims on a favorable basis. Won motions for summary adjudication dismissing consumer claims on collateral estoppel grounds against bellwether plaintiffs.
  • Defended numerous putative class actions against automobile manufacturers such as BMW, Hyundai, Honda, and Maserati. Secured dismissal with prejudice at the pleading stage of an automobile manufacturer by making a novel argument that the case is prudentially moot based on a national recall. Cheng v. BMW of N. Am., LLC, 2013 U.S. Dist. LEXIS 107580, 2013 WL 3940815 (C.D. Cal. July 26, 2013).
  • Secured dismissal with prejudice of a government contractor that delivers the personal vehicles of United States military personnel to and from various domestic and international locations with a motion to dismiss raising a standing challenge.
  • Drafted numerous petitions to compel arbitration that were granted and that have been affirmed on appeal.
