Bandspeed has moved upstream, targeting semiconductor vendors Broadcom, Marvell, MediaTek, Qualcomm, STMicroelectronics, and Texas Instruments in six new filings. (Last spring, plaintiff Bandspeed, at one time a developer of radio frequency communication products, issued a press release announcing a commercial partnership with defendant Broadcom, its only such announcement since 2011.) Defendants' integrated circuit products that use adaptive frequency hopping for Bluetooth are accused of infringing five patents  (7,027,418, 7,477,624, 7,570,614, 7,903,608, 8,542,643). In two earlier cases filed in 2009 and 2010, Bandspeed sued 20 makers of downstream consumer electronics products with Bluetooth functionality (including Apple, Belkin, Blackberry, Casio, Dell, Garmin, HTC, Kyocera, LG, Motorola, Nintendo, Pantech, Plantronics, Samsung, Sony, TomTom and Toshiba). Accused products included mobile handsets, personal computers, gaming and navigation devices, and headsets. LG, the last remaining defendant in the 2009-2010 filings, was dismissed with prejudice on May 1, 2014. 5/9, Western District of Texas, 1:14-cv-00433, 1:14-cv-00434, 1:14-cv-00435, 1:14-cv-00436, 1:14-cv-00437, 1:14-cv-00438.
