Zhone Patent Asserted in New Campaign against Verizon
- February 5, 2013
Bandwidth Management Innovations (BMI) filed suit against mobile network operator Verizon Wireless alleging that Verizon’s network products, including the 3G network, infringe a patent related to a network congestion control system (6,826,620). This is the first patent infringement suit filed by BMI. The patent-in-suit originated with Paradyne and was later assigned by Zhone Technologies to Patent Business Development in February 2011 then to Clearwater in May 2012, which executed an assignment to Internet Voice Solutions on the same day. In December 2012 Internet Voice Solutions assigned the patent to BMI. RPX reviewed the patent-in-suit as part of an open market opportunity (Zhone-Acq) in August 2009. A prior dispute between Zhone and Paradyne brokers Robert Westerlund and Eric Dowling erupted in May 2010 alleging breach of agreement over payment of a specified percentage of net revenues. A stipulated dismissal was entered on February 14, 2011, the same day Zhone assigned several patents to Patent Business Development. Westerlund is listed as the correspondent for Patent Business Development. 2/4, District of Delaware, 1:2013cv00191.
