Eight Khz LLC is a non-practicing entity (NPE) involved in patent assertion. The company's patent portfolio focuses on technologies related to binaural sound and wearable electronic devices, specifically methods of delivering binaural sound through electronic earphones.
The company's patent litigation posture is that of an NPE asserting its acquired portfolio. Eight Khz LLC has been involved in three tracked cases: one as a plaintiff and two as a defendant. The plaintiff case was filed in the Western District of Texas, a venue known for patent litigation.
A notable case involves Eight Khz LLC as the plaintiff against Meta Platforms, Inc. in the Texas Western District Court, alleging patent infringement related to binaural sound technology. Meta Platforms, Inc. subsequently challenged the validity of Eight Khz's patents at the Patent Trial and Appeal Board (PTAB). In December 2024, the PTAB ruled that Meta successfully demonstrated that all claims in two of Eight Khz's patents (U.S. Patent Nos. 10,448,184 and 10,368,179), relating to methods of delivering binaural sound through electronic earphones, were invalid as obvious. Despite the PTAB's decision, the federal court lawsuit in Texas is scheduled for trial in October 2025.
