Senior Counsel

Robert J. Kriss

Professional Liability, Consumer Litigation & Class Actions, Product Liability & Mass Torts


Robert Kriss has extensive experience resolving disputes involving information technology outsourcing, software development, cybersecurity, e-commerce, financial services and real estate. In addition, as a result of his experience litigating a broad range of statutory, contract and tort claims over the years, Bob is often retained to address matters that require an interdisciplinary approach or novel applications of fundamental principles in new contexts.

Bob has been particularly effective in resolving disputes at early stages of proceedings through alternative dispute resolution, motions to dismiss, motions for summary judgment and settlements. When early resolution has not been possible, Bob has successfully tried cases before judges, juries, arbitrators and appellate courts. For example, Bob secured an international arbitration award in a real estate development dispute valued at more than $80 million dollars and won an award on behalf of a customer in an international arbitration involving a failed software product. He also has won arbitration awards in financial disputes and secured favorable judgments after bench and jury trials in commercial, product liability, antitrust and civil rights litigation. Bob has taught trial practice as an adjunct professor at Northwestern Law School.

Bob joined Mayer Brown in 1978. He has been recognized by inclusion in such publications as Leading Lawyers in Illinois, Illinois Super Lawyers, Who's Who in the World, Who's Who in American Law, Who's Who in America and The Best Lawyers in America. He holds Martindale Hubbell's highest A/V rating (AV Preeminent) and has been recognized by the publication as among the "Top Rated Lawyers of Technology Law."
