SK Hynix faces US patent fight over HBM, 3D NAND

SK Hynix is facing a cascading legal challenge in the U.S. over HBM and 3D NAND patents, with a second investigation by the U.S. International Trade Commission and concurrent federal litigation. This threatens its market positioning in North America, forcing potential shifts in R&D strategies toward alternative architectures and IP licensing models. Compliance risks are escalating, particularly in supply chain resilience and technical standard alignment, prompting global semiconductor firms to reassess ties with U.S. partners. Competitors such as Micron and Samsung may leverage this moment to expand their patent portfolios and capture market gaps. In the short term, the industry is likely to see fragmentation in technology roadmaps, while long-term trends point toward a decoupled global storage chip ecosystem. Key players in Taiwan and Hong Kong, China, may emerge as pivotal nodes in this evolving landscape.
