DSS Technology Management, a subsidiary of DocumentSecuritySystems, named Apple as the defendant in the entity’s first lawsuit (5,699,357; 6,128,290). The case asserts two patents that have not been previously seen in litigation. Both patents relate to a network system for coordinating a plurality of electronic devices on a single system. In the complaint, Apple’s computers are accused of infringing the patent for providing wireless Bluetooth connectivity to a multiple peripheral devices, such as a mouse and keyboard. The patents-in-suit originated with BBN Corporation and were eventually assigned to Stragent in 2008. RPX reviewed the asserted patents as part of an open market opportunity offered by Stragent in February 2013. They were then transferred to Lexington Technology Group in July of this year and a month later, assigned to DSS Technology Management. The entity publicized this acquisition in late November. At the time, it also mentioned acquisition of a second portfolio related to semiconductor manufacture. Those patents have not yet been seen in litigation. Document Security Systems has a number of subsidiaries but DSS Tech is only the second to file patent assertion litigation. The other is Bascom Research, an entity that filed a number of suits in late 2012, most of which have since ended. 11/26, Eastern District of Texas, 6:13cv00919
