Aperçu

Mayer Brown’s Trade Secrets team helps clients identify, protect, manage, and enforce their most valuable proprietary information across jurisdictions and industries. We advise on all aspects of trade secret protection, from developing comprehensive protection programs, conducting trade secret audits, and strengthening information governance practices to safeguarding confidential information in commercial relationships, strategic transactions, and workforce transitions. We help clients not only respond to threats, but also implement practical measures designed to mitigate risk and prevent disputes before they surface.

Trade secrets and confidential business information are often among a company’s most valuable assets. In an increasingly competitive, technology-driven, and mobile business environment, companies face growing risks from employee mobility, business partner disputes, cyber incidents, reverse engineering, and the unauthorized use or disclosure of proprietary information. Protecting these assets requires legal strategies that align with business objectives, support innovation, and safeguard competitive advantage.

When trade secret disputes arise, we move quickly to help clients investigate potential misappropriation; secure and preserve critical evidence; obtain temporary restraining orders (TROs), preliminary injunctions, and other emergency relief; and pursue or defend high-stakes claims in courts and arbitral forums worldwide. Our lawyers regularly handle matters involving employee departures, competitor disputes, business partner conflicts, restrictive covenant enforcement, reverse engineering allegations, and complex digital evidence and e-discovery issues. Clients frequently turn to us at the outset of a dispute, when swift action can be critical to protecting trade secrets and preserving competitive advantage.

Clients rely on Mayer Brown for practical advice, rapid response capabilities, and trial-ready advocacy in matters involving their most important intellectual assets. By combining strategic counseling, investigations, and sophisticated dispute resolution experience, we help organizations protect the information, know-how, and innovation that drive long-term business success.
