USITC Opens Investigation Into SK hynix Patents
The U.S. International Trade Commission on March 31, 2026 opened an investigation into MonolithIC 3D’s claim that SK hynix and Kioxia infringed eight U.S. patents covering 3D stacked memory architectures, including HBM and 3D NAND. The probe under Section 337 could lead to U.S. import bans or licensing negotiations, with the USITC setting a target completion date within 45 days.
Scoring Rationale
High score because the USITC's official investigation is new, credible, and has industry-wide implications for memory supply and AI infrastructure. Score is boosted by authoritative sources and timeliness, with limited deduction because the news is legal/sectoral rather than a technical breakthrough.
