IQVIA Inc. v. Superior Court of California, Alameda County

Issue: Whether, in a preemptive action brought by a former employee subject to a noncompete agreement who joins a competitor seeking a declaration that the agreement is unenforceable, the due process clause of the 14th amendment, as construed in Walden v. Fiore, permits a state court to exercise specific personal jurisdiction over an out-of-state defendant when the plaintiff does not reside in the forum state, the noncompete agreement was formed in another state, and the employment relationship was based in another state, on the ground that enforcement of the agreement would prohibit the plaintiff from working for an employer headquartered in the forum state.
