Marc S. Williams

Marc is an accomplished civil litigator who is entrusted by clients of every size—from startups to the Fortune 500—to handle bet-the-company cases. He routinely obtains outstanding results at all stages of litigation. His experience in the complex litigation arena includes business litigation, partnership disputes, fiduciary duties, contractual disputes, fraud, securities litigation, unfair competition, business torts, legal malpractice, trade secrets, copyright, trademark, idea submission, rights of publicity, defamation, entertainment, real estate, and healthcare. 

Described by one client as "absolutely terrific at trial," Marc has earned a reputation in the courtroom for his impressive results. Over a recent span of nine months, he tried three jury trials to verdict, all of which resulted in resounding victories for his clients. His success rests largely on his strategic focus and analytical prowess. Whether writing a brief, cross-examining a witness, or presenting to the court, Marc homes in on the key levers of a case and uses them to drive his argument forward. In particular, he excels at translating intricate legal theories into clear, convincing narratives that win jurors' support. 

Marc's clients also value his business-like perspective on litigation. While he develops every case with a view toward trial, he ultimately seeks to support his clients' objectives through cost-efficient, creative solutions. With their bottom line as his guiding principle, he considers all available tools and avenues to determine which will deliver the greatest reward with the least risk and cost. His pre-trial strategizing often results in successful dispositive motions and settlements, leaving clients free to resume business as usual.

Known as pragmatic and forthright, Marc builds trust through genuine collaboration. He maintains open lines of communication to guide clients through the benefits and drawbacks to every decision. When difficult judgment calls must be made, he relies on his decades of experience to suggest—and pursue—the most advantageous path to resolution. 

Before co-founding Cohen Williams in 2014, Marc was a partner at One LLP, an entertainment and intellectual property boutique litigation firm. Previously, he spent ten years as a litigator at O’Melveny & Myers LLP’s Los Angeles and Century City offices.
