Digital Signal Innovations Sues SecuriMobile

December 14, 2012

Digital Signal Innovations (DSI) filed suit against SecuriMobile alleging that SecuriMobile’s mobile security products and services, as well as their consulting services infringe a patent related to modem security.  According to the complaint, DSI sent letters providing notice of infringement to the defendant on December 3, 2012.  DSI has filed more than 10 suits since November 2012. The patents-in-suit are part of a portfolio of patents originating from AT&T/Lucent spin out, Paradyne. In September 2004, Paradyne retained brokers Robert Westerlund and Eric Dowling to represent Paradyne in the sale or licensing of their patents. The agreement specified that each would be paid 7.5% of up to ten million in net revenues. A year later, Paradyne was acquired by Zhone Technologies. In May 2010, Westerlund and Dowling sued Zhone for $750,000 in damages from alleged breach of the agreement between Westerlund and Dowling and Paradyne. A stipulation of dismissal in the case was entered on February 14, 2011, the same day Zhone assigned 58 patents to Patent Business Development. Westerlund is the correspondent for Patent Business Development on the assignments. Since October 2012, patents assigned to Patent Business Development in February 2011 have been asserted in suits filed by related entities Digital Signal InnovationsDriden Communications, Innovative Communications, and Telecomm Innovations. (Other patents originating from Paradyne/Zhone and formerly controlled by Rembrandt IP have been asserted in the unrelated Brandywine Communications campaign.) 12/12, District of Delaware, 1:2012cv01705.
