Summary of Allegations and Outcome:
Palisade Technologies, LLP alleged that Micron's DRAM, NAND Flash, NOR Flash memory products, and solid-state storage devices infringed on five of their patents, including the '838 patent. The complaint was filed on October 16, 2024.
Micron responded to the lawsuit, and in July 2025, the court recommended granting in part and denying in part a motion to dismiss from Micron. The court found that Palisade's allegation of pre-suit knowledge based on the '838 patent being cited by a USPTO examiner during the prosecution of an unrelated Micron patent was not sufficient to support a claim of pre-suit willful infringement.
The parties reached an agreement to end the dispute, and a joint motion to stay the case for 45 days to finalize their agreement was filed. Subsequently, on January 26, 2026, the court ordered the dismissal of all of Palisade's infringement claims with prejudice, permanently barring them from refiling the same claims. Micron's counterclaims and defenses were dismissed without prejudice.
In a related action, Micron Technology Inc. filed for an Inter Partes Review (IPR) against Palisade Technologies, LLP at the Patent Trial and Appeal Board (PTAB) for U.S. Patent No. 8,327,051 B2 and U.S. Patent No. 9,281,314 B1, which were also part of the district court litigation.
