Matthew F. Prewitt is a trial lawyer with a national practice advocating for Schiff Hardin’s clients in disputes arising from the theft and misuse of confidential and private information, breaches of restrictive covenants in commercial and employment relationships, and related breaches of trust and loyalty. Matt also frequently advises clients on protection of sensitive competitive and personal information, information governance, and the intersection of the law of trade secrets, privacy, and data security.

Clients turn to Matt for swift, decisive courtroom victories when time is of the essence. As lead trial counsel, Matt has won emergency injunctive relief in expedited proceedings in more than a dozen states. Matt has extensive experience investigating and trying complex claims for theft and destruction of electronic data and has won case-terminating sanctions for destruction of computer data in multiple suits. Matt also has unusually deep experience in enforcement proceedings to compel compliance with injunctions and to win remedies for violations of court orders. Matt has won case terminating or dispositive sanction awards for litigation misconduct and violation of injunctions in numerous suits, often prevailing under a heightened burden of proof to win punitive sanctions.

Matt provides strategic advice and counseling for clients seeking growth through lateral competitive hiring, guiding the client through the recruitment, hiring, and onboarding process to mitigate litigation risk when hiring employees subject to restrictive covenants and nondisclosure obligations.

As a trial lawyer who regularly leads the prosecution and defense of complex, fast track injunction proceedings, Matt has learned how to triage the potential factual and legal issues to develop a focused, winning strategy that achieves the client’s business objectives. Matt knows how to litigate as a plaintiff, by seizing the initiative and framing the issues for trial.

Matt applies these skills in “rescue” engagements where he is called upon to augment or replace prior trial counsel at an advanced stage of the case. These engagements have provided Matt substantive experience in a broad range of business, environmental, and mass tort disputes in both the trial courts and in bankruptcy proceedings.

Matt is a Certified Information Privacy Professional (CIPP-US). He is also an adjunct professor of law at Chicago-Kent College of Law where he has taught courses on complex pretrial litigation and the law of data privacy. Matt is an active participant in The Sedona Conference Working Group 1 (Electronic Document Production and Retention) and Working Group 11 (Data Security and Privacy Liability) as well as the newly formed Working Group 12 (Trade Secrets). He is a member of the International Association of Privacy Professionals.

  • Experience

    • Portola Packaging v. Logoplaste USA, et al. (Cook Cty. Ill.) Lead trial counsel for defendants in complex trade secrets dispute between competing manufacturers of plastic packaging, involving extensive cross-border discovery. Defendants won summary judgment on all claims, and the court awarded defendants recovery of their attorney fees as a sanction against plaintiff for commencing the suit in bad faith after Matt obtained evidence that the plaintiff’s general counsel had submitted materially false affidavits to the court. The victory was profiled in a "How They Won It" feature in Law360 and reported widely in the legal press as the first time an Illinois court had awarded a trade secrets defendant its entire fees for a complex, multi-year litigation.
    • Bunnett & Company, Inc. v. Natural Soda, LLC (Travis Cty. Tex.)  Lead trial counsel in a suit arising from the resignation of our client’s former general manager and the manager’s attempt to form a competing business with other key employees and a long-term exclusive supplier.  Matt won a TRO and a criminal contempt finding against the supplier, which was sustained on expedited appeal to the Texas Supreme Court on the eve of a jury trial.  Before the jury, Matt won a substantial verdict of both actual and punitive damages.  The contempt proceedings and subsequent jury verdict were widely reported in the legal press.
    • Energy Feeds Int’l v Dores (W.D. Tex. and E.D Cal. Bankr.) After we won a TRO against our client’s departing manager, the defendant sought bankruptcy protection to invoke the automatic stay against further proceedings.  After extensive discovery and two bench trials, Matt won dismissal of the bankruptcy case on grounds of fraud and won a finding of contempt against the defendant and others for engaging in an elaborate scheme to hide the former manager’s continuing competitive business activities and receipt of compensation in under the table payments from a competitor, despite his claims before both courts that he was psychologically disabled and unemployed.
    • Confidential Matter in Delaware Chancery and Federal District Court.  Matt represented a private equity investor in a suit against a selling shareholder, founder, and former senior executive of an acquired business, who attempted secretly to form a competing business with other former employees in breach of restrictive covenants in the stock purchase agreement. Matt commenced separate proceedings against both the employees and the former executive and, after obtaining the employees’ videotaped testimony identifying the shareholder as the instigator of the strategy, won a favorable settlement under which all defendants exited the industry entirely for an extended term, and the former shareholder disgorged a substantial part of the consideration for his shares.
    • JLG Industries v. Baxter (Kane Cty. Ill.) Lead trial counsel for a manufacturer against the departing director of strategic planning, who attempted to resign and join a competitor immediately after completing our client’s secret plan for redesign of its product fleet.  In expedited proceedings, Matt won a TRO and then a case-dispositive order of contempt against the departing director.  In a multi-day bench trial, Matt and the Schiff Hardin team presented extensive and complex computer forensics evidence to prove that the director had copied and retained competitive information in violation of the TRO.
    • Brighton Associates v. Toper (Cook Cty, Ill.)* As lead trial counsel for a consulting firm, Matt won a TRO on New Year's Eve, enjoining three of plaintiff's former executives from continuing to operate a competing business they had secretly organized while still employed with the plaintiff. Following entry of the TRO, the parties reached a confidential settlement.
    • Krumwiede v. Brighton Associates (N.D. Ill.)* Lead trial counsel in successful litigation on behalf of consulting firm against a departing vice president.  Matt won a TRO requiring return of the company’s confidential information and in subsequent contempt proceedings presented complex computer forensics evidence to win case-dispositive sanctions against the former vice-president.  The decision is still widely cited as the first case in which a federal court awarded dispositive sanctions for alteration of file metadata.
    • Confidential Clients. Matt is national counsel for talent recruitment and retention for multiple clients, providing regular advice on compliance, training, and litigation preparedness and avoidance as well as representing clients in litigation matters across the United States.

    *Handled prior to joining Schiff Hardin.
