HP won a German patent-infringement judgment against Ninestar, now Pantum, over G&G parallel imports of unauthorized remanufactured HP 963XL cartridges.
The court found the products infringed HP’s EP3530470 patent, ordering sales to stop, accounts to be rendered, damages paid, legal fees covered.
Ninestar and three subsidiaries appealed; the ruling held Pantum liable despite not directly selling the products in Germany.
In fiscal 2026, HP also secured two Unified Patent Court preliminary injunctions against resellers involving 924 and 937 cartridges.
HP reported removing more than 1,700 infringing Amazon listings in Q1 2026 tied to HP 210, 218, 219, 220 cartridge models.
