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.
Rembrandt Wireless Technologies, LP (Rembrandt WT) has filed suit against Apple (2:19-cv-00025), accusing the company of infringing the same two wireless communications patents first asserted against Samsung in 2013. That earlier case ended this past August in a dismissal with prejudice after the parties notified the Eastern District of Texas of their settlement—following a jury verdict in Rembrandt WT’s favor, a Federal Circuit appeal of the resulting judgment, and multiple inter partes reviews (IPRs) of the two patents. As in the Samsung case, Rembrandt WT targets products implementing versions of the Bluetooth protocol that support Enhanced Data Rate (EDR), 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”, this new complaint listing Apple products allegedly offering Bluetooth EDR support, including certain iPhones, iPads, iPod Touches, iPod Nanos, Apple Watches, Apple TVs, Airport Extremes, AirPods, HomePods, and Beats wireless headphones and speakers.
