Section 16600 of California’s Business and Professions Code provides that “Except as provided in this chapter, every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void.” There are statutory exceptions in sections 16601, 16602 and 16602.5 for noncompete provisions relating to sales of businesses, dissolutions of partnerships or dissociations of a partner from a partnership, and a dissolution of a limited liability company or a termination of a member’s interest in a limited liability company, but not for noncompete provisions against former employees.
The appeals court decision is a timely reminder that although reasonably tailored confidentiality provisions that protect an employer’s trade secrets and proprietary information will be enforced, overbroad clauses that have the practical effect of a covenant not to compete will not be enforced.
