Display Technologies, LLC, one of the many NPEs controlled by inventor Leigh M. Rothschild, has rebooted its sole litigation campaign with four new lawsuits against BLU Products (2:17-cv-00067), HTC (2:17-cv-00070), LG Electronics (2:17-cv-00069), and ZTE (2:17-cv-00068). The companies are accused of infringing a single media transfer patent (9,300,723) related to the one asserted in previous lawsuits (8,671,195), which targeted makers of Wi-Fi-enabled digital cameras and related image transfer apps (C&A IP Holdings, JK Imaging, Ricoh, GoPro) along with providers of software allowing media transfer and streaming (NVIDIA, Sony, Samsung, Valve). At issue in the new complaints are Android-based smartphones offering Android Beam, a file-sharing feature that uses near-field communications (NFC) to initiate Bluetooth file transfers to another device.
