District Court Litigation

Advanced Memory Technologies, LLC v. SK Hynix Inc.

  • Plaintiff: Advanced Memory Technologies, LLC
  • Defendant: SK Hynix Inc.
  • Jurisdiction: U.S. District Court for the Eastern District of Texas
  • Case Number: 2:24-cv-01078
  • Filing Date: December 30, 2024
  • Status: Active/Pending. In an amended complaint filed on April 2, 2025, Advanced Memory Technologies, LLC added U.S. Patent No. 8,400,835 to the list of patents allegedly infringed by SK Hynix. A trial in this matter is scheduled to begin on October 5, 2026.

There is no publicly available information to indicate that U.S. Patent No. 8,400,835 has been asserted in the separate litigation between Advanced Memory Technologies, LLC v. Micron Technology, Inc. (Case No. 1:25-cv-01036) in the U.S. District Court for the Western District of Texas.

Patent Trial and Appeal Board (PTAB) Proceedings

In connection with the district court case against SK Hynix, a petition for an Inter Partes Review (IPR) was filed with the Patent Trial and Appeal Board, challenging the validity of U.S. Patent No. 8,400,835.

  • Case Number: IPR2025-01453
  • Petitioner: SK Hynix Inc.
  • Patent Owner: Advanced Memory Technologies, LLC
  • Filing Date: August 25, 2025
  • Outcome: Not Instituted - Procedural. The PTAB declined to institute a review of the patent. The "procedural" basis for this decision often relates to factors and policies concerning the Board's discretion, such as the advanced stage of a parallel district court proceeding on the same patent. This avoids duplicative efforts and potentially conflicting outcomes between the PTAB and the district courts.
