Commercial Litigation

Osborn Maledon's commercial litigation attorneys are extremely experienced in handling particularly complex litigation on a broad range of matters, including class actions and multi-district litigation, and in cases alleging securities and antitrust violations, misuse of intellectual property, consumer fraud and product liability.  We also work extensively with educational institutions and government entities in litigation and regulatory matters. In addition, our appellate lawyers represent clients before the Arizona Court of Appeals, the Arizona Supreme Court, and the Ninth Circuit Court of Appeals and have been recognized as leaders among the appellate bar. 

For example, we have successfully:

  • Defeated in arbitration a multi-million dollar claim by a supplier against a Fortune 50 manufacturer
  • Represented a pharmaceutical company in a multi-million dollar dispute with a manufacturer of its products
  • Represented a publicly traded bioscience company in a dispute arising under a stock purchase agreement
  • Represented several large real estate developers in disputes relating to contract terms or other contractual interpretation issues
  • Represented numerous large insurance companies in coverage disputes, including bad faith litigation
  • Represented a national sports organization in several complicated endorsement contract disputes and other complex litigation matters
  • Represented a multi-national company in connection with litigation related to the sale of a business
