Eight months after a settlement ended years-long litigation against Samsung in the Eastern District of Texas, and three months after suing Apple in that same district, Rembrandt Wireless Technologies, LP (Rembrandt WT) has filed a pair of Central District of California lawsuits, one each against Broadcom (8:19-cv-00708) and Qualcomm (8:19-cv-00705). Both companies are accused of infringing two wireless communications patents through the provision of various semiconductor products that implement Bluetooth—from single-chip Bluetooth products to full systems-on-chip—and that allegedly support various versions of the Bluetooth Enhanced Data Rate (EDR) specification, including “Version 2.0 + EDR, Version 2.1 + EDR, Version 3.0 + HS, Version 4.0 + LE, Version 4.1, Version 4.2, or version 5”. Meanwhile, Rembrandt affiliates and the remaining defendants in a separate campaign have submitted competing approaches in Delaware for dealing with a Federal Circuit remand of a $51M attorney fees award against the NPEs.
