Whether secret formulas/recipes, algorithms, manufacturing techniques, or valuable business information (e.g., customer lists), Calfee’s Trade Secret practice is adept at recognizing and documenting trade secrets, which can be critical for establishing prior user rights and seeking relief for misappropriation.

Calfee’s trade secret attorneys have experience representing both plaintiffs and defendants in trade secret matters across diverse industries, involving both state and federal law. We also have experience coordinating with law enforcement officials during trade secret theft investigations.

Calfee’s attorneys have worked closely with clients to establish workplace cultures (e.g., standards and controls) that foster the safekeeping of trade secrets. We partner with clients to perform periodic audits to ensure that trade secret portfolios evolve as a company’s proprietary technology evolves.

Our trade secret lawyers frequently assist clients with trade secret-related issues, such as drafting and reviewing agreements with third parties involving the sharing of trade secrets, as well as providing guidance on leveraging proprietary technology to strengthen a company’s brand and, thus, its valuation.
