Mr. Valenti practices in the areas of government enforcement (defense, investigations, and compliance) and litigation, focusing on clients involved with financial services, energy, health care, information technology, or media. 

He assists clients in settling or litigating cases involving a government party, focusing particularly on white-collar criminal defense. However, he also has experience with parallel proceedings, standalone civil or administrative enforcement actions, and cases involving civil-rights violations or tortious conduct by federal or state actors. 

Mr. Valenti has counseled clients regarding matters investigated by the DOJ, FBI, SEC, IRS, FEC, FTC, DEA, FDA, HHS, EPA, OSHA, IG offices, and corresponding state agencies. In addition to representing subjects, targets, and defendants, he has represented third-party witnesses and potential investors seeking to evaluate risks related to pending enforcement actions, such as potential forfeitures or clawback lawsuits. 

In both enforcement-related and standalone representations, Mr. Valenti has undertaken significant internal investigations of business activities or individuals associated with his clients. Some of these investigations have addressed workplace fatalities, anonymous threats, complex fraud, foreign corrupt practices, terrorist financing, money laundering, employee theft, and negligent maintenance of industrial facilities. 

He also provides risk mitigation and compliance advice, with a particular emphasis on anti-corruption and regulatory compliance for companies doing business with government entities. 

In his broader commercial litigation practice, Mr. Valenti advises clients on all aspects of copyright, trademark, and free-speech law. He assists clients in advancing and defending claims of copyright infringement, trademark infringement, misappropriation of trade secrets, unfair competition, false advertising, defamation, commercial disparagement (trade libel), and invasion of privacy.
