California Employment Contract Review
Reviewing a job offer or employment agreement in California? The clauses that matter most, the non-compete, invention assignment, and arbitration, are governed by California law, and the same clause can be enforceable in one state and void in the next. Here is how California treats each, and what ClauseAudit checks before you sign.
Non-compete in California
Generally void, good news for employees
Are non-competes enforceable in California?
Employee non-competes are void and unenforceable under Business & Professions Code §16600. Employers can even face penalties for requiring them.
Governing law: California Business & Professions Code §16600.
Whatever the label in your contract, California courts look at whether the restriction is reasonable in duration, geography, and scope. A nationwide, multi-year, whole-industry ban is far more likely to be narrowed or struck down than a narrow one.
Who owns what you invent in California?
California has a statute protecting inventions you create on your own time, with your own resources, unrelated to your employer's business, similar to California Labor Code §2870. A blanket assignment of "all inventions" that ignores this carve-out may be unenforceable as to your personal projects. Look for the statutory exclusion in your agreement.
Arbitration and class-action waivers in California
California is among the states that have acted to limit forced arbitration of certain employment claims, though many clauses remain enforceable under federal law. Check whether the arbitration clause is mutual and whether it waives your right to join a class action.

What if I work in California but my employer is in another state?
It matters, because California's neighbours do not all treat non-competes the same way: Arizona (generally enforceable), Nevada (generally enforceable), Oregon (limited). Which state's law applies turns on the governing-law and venue clauses in your contract and on where the work is actually performed, so those two clauses are worth reading closely before you sign.
What else should I check in a California employment contract?
Beyond the non-compete: how invention assignment is worded and whether it reaches work done on your own time; whether disputes go to arbitration and whether class actions are waived; whether notice periods are symmetrical between you and the employer; and how any equity vests, including what happens if you leave before a cliff.
