The following is a representative sample of Mr. Thomasch’s cases.*
Litigation for Big-Four Accounting Firms
- Fraud and Breach of Contract: Mr. Thomasch is lead counsel for PwC and multiple individuals in an action brought in California Superior Court by the City of Los Angeles (“City”) alleging fraudulent inducement and breach of contract in the implementation of a new Customer Information System for the City’s Department of Water and Power (LADWP). During discovery, Mr. Thomasch and his team uncovered evidence that the City’s counsel had perpetrated a massive fraud on the Court in a related case, in order to facilitate the City’s efforts to blame PwC falsely for problems with LADWP’s new billing system. That evidence forced LADWP’s highest ranking employee to resign; that individual then pleaded the Fifth Amendment at his deposition, as did lead counsel for the City and lead counsel for the plaintiff class in the related case. As was widely reported in newspapers and other media, the FBI thereafter raided the offices of LADWP and the City Attorney. In addition to the on-going federal investigation, the trial court appointed a Special Master to investigate the City’s wrongdoing. Faced with an array of adverse rulings by the trial court, the City dismissed with prejudice all claims against PwC and the individual defendants. PwC has informed the Court that it will be filing a motion for sanctions against the City.
- Wage and Hour Class Actions: As lead trial and appellate counsel for PwC in multiple wage-and-hour class actions, Mr. Thomasch argued and won in the Ninth Circuit an appeal of an issue of first impression under the California Labor Code, obtaining reversal of the District Court’s summary adjudication in favor of a class of approximately 2,000 unlicensed accountants.
- ERISA: Mr. Thomasch currently represents PricewaterhouseCoopers LLP (“PwC”) in a high-stakes ERISA class action pending in the Southern District of New York, in which Plaintiffs seek to compel payment of “whipsaw claims” exceeding $1 billion.
- Arbitration of Misrepresentation Claims: As lead counsel for a Big Four accounting firm, Mr. Thomasch successfully moved the New York Supreme Court to compel arbitration of a threshold issue in New York, and to stay a complaint alleging fraudulent misrepresentations and omissions filed against the firm in Superior Court of California, County of Los Angeles. The California plaintiff appealed that ruling, and the appeal is pending before the Appellate Division.
Product Liability and Mass Torts
- Wyeth: Served as national lead trial and appellate counsel in nearly 400 product liability cases involving claims that childhood vaccines containing the preservative thimerosal caused autism in vaccinated children, prevailing in every case. Successfully tried a two-week Frye hearing in which Wyeth attacked all causation theories purporting to link vaccines to autism, resulting in the exclusion of all of plaintiffs’ expert witnesses. Argued the appeal to Maryland’s highest court and obtained a unanimous affirmance, which effectively adopted a new standard for the admissibility of expert testimony in civil cases, Blackwell Wyeth, 408 Md. 575, 971 A.2d 235 (2009). That decision resulted in the dismissal of the claims of all of the approximately 300 plaintiffs in cases then-pending against vaccine manufacturers in Maryland. Devised federal preemption strategy that ultimately resulted in the successful conclusion of the national litigation, and argued preemption motions and appeals in state and federal courts, leading to the Supreme Court’s decision in Bruesewitz v. Wyeth, in which the Court held that all design defect claims involving recommended childhood vaccines are preempted by the National Childhood Vaccine Injury Act of 1986.*

- U.S. Mobile Phone Carrier: Trial and appellate counsel in a patent infringement jury trial in the District of Nebraska. After a multi-week trial, the jury returned a complete defense verdict, finding that all five accused networks to did not infringe any of the six asserted patent claims.

Mr. Thomasch first-chaired and won a bet-the-company jury trial in the District of Delaware in which DAS prevailed against a competitor asserting patent claims that were alleged to cover all transgenic corn products, both commercial and pre-market, in the United States. He won a qui tam suit against DAS in which plaintiff alleged false marking under 35 U.S.C. § 292. Mr. Thomasch also argued appeals before the Federal Circuit in multiple cases involving patents asserted by and against DAS, and DAS prevailed in each such appeal.*
