SK hynix Patent Fight Adds Legal Overhang to HBM and 3D NAND

SK hynix is facing a broader US patent dispute involving MonolithIC 3D, with a second ITC investigation now covering HBM and 3D NAND products as federal litigation continues in parallel. The compact source does not describe an import ban, customer disruption, or production halt. For RamTrend, the significance is risk rather than confirmed supply impact. HBM is central to AI accelerator supply, while 3D NAND remains important to storage markets. If the dispute were to create licensing costs, sales restrictions, or settlement pressure, it could affect margins or product availability. At this stage, the pricing impact should be treated as uncertain.
