Plaintiffs entered into arbitration agreements with Pacific as part of their agreements for Pacific’s cryogenic preservation of their sperm or eggs. One of the cryogenic tanks in which the specimens were to be preserved failed. This decision holds that the manufacturer and distributor of the failed tank could not compel arbitration under the plaintiffs’ agreements with Pacific to which the manufacturer and distributor were not parties. The plaintiffs’ products liability and negligence claims against those defendants were not inextricably intertwined with their fraud claims against Pacific even though they arose from the same incident. Nor did those claims arise from plaintiffs’ agreements with Pacific. But for causation–claim would not have arisen but for the contract containing the arbitration clause–is not enough to equitably estop a plaintiff from denying he agreed to arbitrate his claims against the non-signatory.
