Trade Secrets & Employee Mobility


Based in the San Francisco office of Wilson Sonsini Goodrich & Rosati, Charles Tait Graves practices intellectual property litigation and counseling. Tait is well known for his focus on trade secret law. Over the past 15 years, he has handled countless trade secret matters in Silicon Valley and around the country, and frequently writes and lectures in the field. Few globally have similar depth, experience, and insight regarding trade secret-related matters.

Tait is a member of the firm's Nominating and Hiring Committees.

Litigation: Trade secret cases have increased in recent years. From inception through trial and appeal, Tait handles trade secret, nondisclosure agreement, invention assignment, Computer Fraud and Abuse Act, idea submission, work for hire, and similar matters. Through his litigation wins and frequently cited publications, he has helped shape California's trade secret laws by advancing creative theories on issues such as claim identification, statutory preemption of alternative causes of action, the meaning of the statutory phrase "threatened misappropriation," expert damages opinions, choice of law, bad-faith claims, and the application of Business & Professions Code Section 16600 in various contexts. Tait has participated in dozens of trade secret and related cases around the country.

Tait also has litigated a broad range of disputes involving technology companies, including licensing, Lanham Act, copyright, TCPA, and other commercial cases.

Counseling: Many potential problems never result in litigation because clients receive precise and careful counseling. Tait has counseled a vast number of companies—from start-ups to public company enterprises—as well as individuals and investors. This includes pre-dispute counseling, internal investigations, workforce training, clean room development, advising new start-ups and company founders, hiring and mobility, international questions, restrictive covenants, pre-acquisition diligence, and due diligence for venture capital firms. He has assisted clients in fields such as clean technology, solar energy, social networking, medical devices, and a host of other software, Internet, and hardware-based applications. His counseling efforts regularly address cutting-edge questions and unusual contentions.
