The affirmance removes a significant patent litigation overhang for Micron. Traders should watch for potential final resolution or settlement of the underlying district court cases between Netlist and Micron as the IPR validity rulings are now binding. Monitor for any en banc or certiorari petitions from Netlist, though the nonprecedential nature and unanimous three-judge panel make reversal unlikely.
Price Chart
Executive Summary
The Federal Circuit issued three nonprecedential decisions on September 2, 2026, affirming the Patent Trial and Appeal Board's final written decisions that all challenged claims across six patents owned by Netlist are unpatentable as obvious. The rulings cover memory module technology in IPR proceedings where Micron was the real party in interest after Samsung settled. The affirmance eliminates the patent infringement risk to Micron's products, removing a key overhang from the company's litigation exposure with Netlist.
