A former Proskauer Rose LLP executive was hit with a preliminary injunction on Friday in a lawsuit brought against him over trade secrets he allegedly downloaded from the firm to removable media.
Judge Analisa Torres of the US District Court for the Southern District of New York issued the preliminary injunction, which limits the actions of Jonathan O’Brien, who resigned as Proskauer’s chief operating officer in December.
Earlier in January, O’Brien lost his job at Proskauer rival Paul Hastings in the wake of his former firm’s lawsuit against him.
The preliminary injunction orders O’Brien and anyone working with him to refrain from further acts of misappropriation, and from further disclosing or copying the trade secret information. The order further requires O’Brien to account for any Proskauer property he has, and to avoid working or consulting with anyone to whom has provided any of the old firm’s files.
O’Brien is represented by Yankwitt LLP and Beck Reed Riden LLP. Proskauer is represented by itself and Debevoise & Plimpton LLP.
The case is Proskauer Rose LLP v. O’Brien, S.D.N.Y., No. 1:22-cv-10918, 1/27/23.
