Practice Highlights
Fifteen years of antitrust experience
Yoni has represented clients as an antitrust litigator for over fifteen years, seeking to enforce or defend claims under federal and state antitrust law. He has litigated claims for price fixing, supply restriction, exclusive dealing, predatory pricing, patent traps, and other claims. His practice extends to counseling corporate clients on antitrust compliance and ethics programs, as well.
Entertainment litigation
In the hard-fought world of entertainment and sports litigation, Yoni has achieved measurable success for clients in distribution matters, copyright disputes, employee mobility, and other entertainment matters.
Emphasis on technology
Technology often outstrips the state of the law, and that presents a challenge to companies on the leading edge. Much of Yoni's experience relates to emerging or complex technologies that require a simple explanation to a judge, arbitrator, or a jury. Yoni has worked on significant cases in the arenas of computer technology, smartphones, cellular communication, medical devices, SaaS (software as a service), and aviation technology. For any dispute where the technology presents a learning curve, Yoni can efficiently and effectively understand it and apply existing law to benefit the client's goals.
