Dragon Ball was using capsules to store things long before Pokemon did. And Dragon Ball Z, which ended in Japan in '96 had already done storing 'creatures in capsules. Saibamen for one. And after the Saiyan saga Bulma puts her dead friends in coffin capsules.
Nintendo is making a case that the use of capsules to capture and carry creatures is their IP.
