Fed. Circ. Upholds BeSang Patent, Keeps Micron Ruling Intact - Law360

The Fed. Cir. decision is a structural inflection point, not a procedural footnote. BeSang's patent surviving appellate scrutiny locks in enforceable IP over core memory architecture, and the compounding effect on Micron's R&D pipeline dwarfs any single-quarter P&L hit. Every DDR5, HBM3E, or 3D NAND iteration now carries a design-around or licensing cost that wasn't priced into 2024 capex models. The strategic ripple extends well beyond Micron. Samsung and SK Hynix operate at overlapping process nodes and face the same binary: accelerate cross-licensing negotiations or fund parallel invalidity challenges. In the AI-driven HBM supercycle, memory has become the most IP-contested segment in semiconductors. BeSang's validated claim sets a precedent that smaller holders can extract meaningful tolls from the big three, fundamentally reshaping the DRAM/NAND cost structure. Twelve to twenty-four months out, three trajectories are probable: Micron either settles at a premium or escalates to SCOTUS; a wave of design-around patent filings hits Q1 2026; and mid-tier memory players accelerate exits to shed patent exposure. The era of shared process IP as a de facto industry commons is closing.
