Advanced Memory Technologies, LLC

Advanced Memory Technologies, LLC (AMT) is a Texas-based private company that operates as a non-practicing entity (NPE), also known as a patent assertion entity. A corporate disclosure statement filed in federal court identifies its parent company as AMTL LLC. As an NPE, the company does not manufacture products or provide services; its business is centered on licensing and litigating a patent portfolio. Information regarding its founding date, employee count, and revenue is not publicly available.

AMT's activities involve asserting patents related to semiconductor memory technology. The portfolio includes intellectual property covering technologies such as booster circuits, internal voltage generating circuits, and other designs used in flash memory and DRAM modules. Media reports characterize AMT as a "patent troll," a term often used for entities that generate revenue by litigating patents rather than producing goods or services.

The company's patent-litigation posture is that of a patent enforcer. As indicated by its litigation history showing one case as a plaintiff and none as a defendant, AMT initiates lawsuits against technology companies. Its sole tracked case was filed in the U.S. District Court for the Eastern District of Texas, a venue frequently used for patent litigation.

The company's only tracked lawsuit is Advanced Memory Technologies, LLC v. SK Hynix Inc., filed on December 30, 2024. In the complaint, AMT alleges that the South Korean semiconductor firm infringed four of its patents. The complaint also noted that major technology companies like Dell, Microsoft, and Nvidia incorporate the allegedly infringing memory modules from SK Hynix into their own products. In response to the lawsuit, SK Hynix has filed petitions to challenge the validity of AMT's patents at the U.S. Patent Trial and Appeal Board.
