Trade Secret Litigation

We have extensive experience litigating trade secret claims as part of civil lawsuits, criminal prosecutions, and internal investigations. These matters arise with increasing frequency in the context of commercial business separations, including partnership breakups, canceled acquisitions, and the departures of executives – battlefields on which we have secured numerous victories.

The firm has represented clients in disputes over a diverse array of proprietary information, from algorithms and software packages to consumer electronics technologies, business models, and customer lists. We draw on a wealth of experience working with experts in niche industries, as well as specialists in the hard sciences, to secure positive outcomes in even the most complex technical matters.
