He has experience across a wide range of industries and subject matters, including financial markets, antitrust, intellectual property, technology, life sciences, health care, and labor and employment.

Matt has led teams in courts around the country, including in California, New York, and the Ninth and Federal Circuits.

Representative engagements include: obtaining dismissal of a California False Claims Act complaint against several financial institutions serving as remarketing agents of variable-rate municipal bonds; securing the dismissal of a series of market manipulation and consumer fraud lawsuits filed against a cryptocurrency derivatives trading platform in California state and federal courts; obtaining and successfully defending on appeal a summary judgment of noninfringement for a semiconductor component manufacturer; securing and enforcing an arbitration award forcing a union to withdraw a statewide ballot initiative limiting hospital executive compensation; and representing several hospitals in challenges to union-backed local initiatives seeking to cap the compensation that health care providers may receive from insurers.
