Stop Unfair Competition: California Non-Compete Litigation
TL;DR: California law broadly voids post-employment non-competes (Bus. & Prof. Code § 16600; Edwards v. Arthur Andersen), with narrow statutory exceptions for sales of business interests (§§ 16601–16602.5). Courts often strike down broad customer and employee non-solicitation clauses, while trade secret laws still protect confidential information (UTSA). Recent statutes prohibit entering into or attempting to enforce void non-competes in California and provide a private right of action and attorney’s fees (§§ 16600.1–16600.5). Choice-of-law and forum clauses can be limited for workers who primarily reside and work in California (Lab. Code § 925).
California’s Strong Public Policy Against Non-Competes
California’s public policy broadly disfavors contractual restraints on lawful work. With limited statutory exceptions, post-employment non-compete provisions are void in California under Bus. & Prof. Code § 16600, a rule reaffirmed by the California Supreme Court in Edwards v. Arthur Andersen LLP.
Narrow exceptions permit reasonable restraints tied to the sale of a business’s goodwill, dissolution of a partnership, or a withdrawing LLC member’s interest. See Bus. & Prof. Code §§ 16601–16602.5. Outside these contexts, courts generally refuse to enforce post-employment non-competes against workers, even if narrowly drafted.
Related Restrictions: Non-Solicitation, No-Hire, and Confidentiality
Restrictions labeled as non-solicitation or no-hire can be unlawful if they operate as restraints on employment or competition. California courts have invalidated broad customer and employee non-solicitation clauses in the employment context. See, e.g., Dowell v. Biosense Webster, Inc.; AMN Healthcare, Inc. v. Aya Healthcare Services, Inc.; and The Retirement Group v. Galante (explaining that trade secret law, not non-solicitation clauses, is the proper tool to prevent unfair misappropriation).
By contrast, confidentiality and invention-assignment provisions can be lawful when they protect legitimate trade secrets or proprietary information without restraining ordinary competition.
Trade Secrets vs. Unfair Competition
Even though non-competes are generally void, California law prohibits misappropriation of trade secrets and unfair business practices. The California Uniform Trade Secrets Act allows courts to enjoin and award damages for theft or misuse of protected information that derives independent economic value from being secret and is subject to reasonable secrecy measures. See Cal. Civ. Code §§ 3426–3426.11. Employees remain free to use their general skills and knowledge, but not to take or exploit trade secrets.
Recent Developments Strengthening Employee Rights
Recent legislation reinforces California’s non-compete ban. It is unlawful to enter into or attempt to enforce a non-compete that is void under California law, and covered workers have a private right of action with potential injunctive relief and attorney’s fees. See Bus. & Prof. Code §§ 16600.1–16600.5 (including notice requirements for certain employers) and Bus. & Prof. Code § 17200 et seq. These protections apply in California regardless of where or when the contract was signed when the law applies to the worker’s California employment.
Multi-State Employers and Choice-of-Law Issues
California’s policy can limit choice-of-law and forum-selection provisions that would otherwise apply another state’s more permissive rules, particularly for employees who primarily reside and work in California. See Lab. Code § 925 and Bus. & Prof. Code § 16600.5. Employers with national forms should avoid non-compete clauses for California workers and tailor onboarding accordingly.
Note: California treats restraints in some business-to-business agreements differently; in that context, courts apply a rule-of-reason analysis rather than a categorical ban. See Ixchel Pharma, LLC v. Biogen, Inc.
Evidence That Matters
- The precise contract language and any carve-outs or exceptions
- The employee’s role, access, and mobility
- Whether the information at issue qualifies as a trade secret
- The employer’s secrecy measures (NDAs, access controls, training)
- Proof of solicitation or use of confidential information
- Any threatened or actual harm
Preserve emails, policies, device records, and onboarding/offboarding documents.
Remedies in Non-Compete and Trade Secret Cases
Courts may enjoin enforcement of unlawful restraints and prevent threatened or actual trade-secret misuse. In trade secret cases, plaintiffs can seek actual loss and unjust-enrichment damages; in actions under California’s Unfair Competition Law, courts can issue injunctions and restitution. Attorney’s fees may be available under specific statutes (for example, Bus. & Prof. Code § 16600.5) or by contract.
Practical Steps for Employers
- Avoid non-compete clauses for California workers except in sale-of-business contexts authorized by statute.
- Use narrowly tailored confidentiality, IP assignment, and conflict-of-interest provisions.
- Implement reasonable secrecy measures: access controls, need-to-know limitations, labeling, training, and exit procedures.
- When hiring, instruct candidates not to bring or use former employers’ confidential materials.
- If you discover misuse, act quickly to investigate, preserve evidence, and seek targeted relief.
Tip: Tighten Onboarding and Offboarding
Provide clear written instructions, collect devices promptly, and document return of information. This reduces litigation risk and strengthens any future trade secret claims.
Practical Steps for Employees and Candidates
- Review any agreement you are asked to sign; flag non-compete or non-solicitation language.
- Do not take or use a prior employer’s confidential or trade secret information.
- Keep copies of your signed agreements and policies; document your role and responsibilities.
- If threatened with enforcement, do not ignore the notice—consult counsel promptly.
Checklist: Litigation Readiness
- Locate all signed agreements (offer letter, handbook acknowledgments, NDAs).
- Identify any clauses referencing non-compete, non-solicit, or no-hire.
- List systems and data accessed in your role; separate general know-how from trade secrets.
- Confirm return/deletion of former employer materials and devices.
- Preserve communications (emails, texts, messages) related to solicitation or competition.
- Note any threats, notices, or cease-and-desist letters with dates.
- For employers: confirm secrecy measures (access controls, labels, training logs).
FAQ
Are non-compete agreements ever enforceable in California?
Generally no, except in narrow sale-of-business contexts tied to goodwill under Bus. & Prof. Code §§ 16601–16602.5.
Can an employer enforce a non-solicitation clause?
Broad customer or employee non-solicitation clauses in employment agreements are often invalid if they restrain lawful competition. Target trade secret misuse instead.
What if my contract says another state’s law applies?
For employees who primarily live and work in California, Lab. Code § 925 can limit out-of-state choice-of-law and forum clauses.
How fast should I act if trade secret misuse is suspected?
Immediately. Preserve evidence, limit further exposure, and consider seeking a targeted injunction.
