Monitor for any settlement announcements or further claim construction rulings ahead of the October 2026 trial. The denial of this prior art reference increases the likelihood of an adverse verdict or a settlement at a premium. A settlement or jury verdict could have material financial implications, though no damages figure is yet available.

Executive Summary
SK hynix's motion to supplement its expert report with a new prior art reference (Micron U48a DRAM) was denied by the Eastern District of Texas for lack of diligence in pursuing third-party discovery. This is a procedural loss that prevents SK hynix from using a potentially key invalidity argument at trial, increasing the risk of an adverse patent infringement verdict on the '557 and '018 Patents. The ruling is a probability shifter, not a final judgment, but it materially weakens SK hynix's defense ahead of the October 2026 trial.
