Sheppard Mullin’s Trade Secrets team assists clients to protect and maximize the value of their trade secrets and related assets that can drive their success. Trade secret protection is more important than ever given increased workforce mobility and industrial espionage, as well as the advent of technology that makes misappropriation easier than it used to be. The loss of a trade secret can undermine a business’ competitive advantage. We advise clients on “best practices” to avoid misappropriation and on how to mobilize to enforce their rights in the face of threatened misappropriation.

We also defend clients against claims of misappropriation, unfair competition and related claims that have the potential to shut down their business. We understand that successfully defeating such claims as quickly as possible can be critical to the client’s business. We advise our clients how to reduce the risk of such claims and to resolve them efficiently when they are asserted.
