Digital Stream IP, LLC, a Texas-based NPE controlled by Monument Patent Holdings, LLC, has started a new litigation campaign asserting three patents related to digital audio receivers (6,757,913; 7,962,090; 8,265,545). In two filings on March 11, the entity sued Best Buy (2:16-cv-00203) and General Motors (2:16-cv-00204) in the Eastern District of Texas, alleging infringement through the sale of automotive satellite radio units. These are the NPE’s only lawsuits to date.
