Represented the Jones Group and Nine West in a case involving three senior executives who joined Kenneth Cole, allegedly in violation of contractual and common-law duties.
Successfully enforced a non-compete against a top executive of a major title insurance company. The Second Circuit’s decision in the case, Ticor Title Ins. v. Cohen, 173 F. 2d 63 (1999), is one of the most cited non-compete cases in New York.

Represented Oracle Corporation in defending a trade secret claim arising from a failed joint venture.
Won an appeal that reversed previous New York law limiting an insurance company’s exposure to the face amount of the policy it breached, even if the damage far exceeded that amount. The case, Sabbeth Industries v. Pennsylvania Lumberman’s, 238 A.D. 2d 767 (3d Dep’t 1997), later played an important role in Proskauer’s representation of Larry Silverstein in litigation arising from the 9/11 terrorist attack on the World Trade Center.
Served as lead counsel for L-3 Communications in a four-week jury trial resulting from the acquisition of a security detection business. A verdict in favor of the plaintiff, OSI Systems, was later reversed by the Second Circuit, which ruled in favor of L-3 on almost precisely the theory Steve had advanced on summary judgment before the trial court.
