2011

On March 18, 2011, Imperium (IP) Holdings filed a lawsuit in the Eastern District of Texas accusing seven companies of infringing five of its patents. Imperium claims that LG, Kyocera, Nokia, Motorola Mobility, Apple, Sony and RIM have all committed infringement by manufacturing, selling or importing cell phones. The asserted patents all relate to image sensors and, in particular, photodiodes. Each of the five patents came to ESS Technology, Inc. as part of its 2003 acquisition of Pictos Technologies, Inc. from Conexant Systems, Inc.

On February 25, 2011, Motorola Mobility and its subsidiary General Instrument filed a patent infringement lawsuit against TiVo Inc. Motorola is alleging TiVo’s digital video recorders (DVRs) infringe three of its patents. The asserted patents were originally assigned to Imedia Corporation, whose assets were acquired by General Instrument, which was later acquired by Motorola.

On January 24, 2011, Sharp filed two complaints claiming infringement of seven of its LCD-related patents. A lawsuit was filed in Delaware against AU Optronics Corp. and a complaint was filed with the ITC naming AU Optronics, BenQ Corp., Haier Group, LG Electronics, SANYO Electric Co., TCL Corp. and VIZIO, Inc. Sharp has previously tested the litigation waters with one of these seven properties: U.S. Pat. No. 7,057,689 (hereafter ‘689). In August 2007, Sharp filed an infringement claim in the Eastern District of Texas against Samsung.

In June of 2010, a company going by the name of Gooseberry Natural Resources LLC initiated patent infringement lawsuits against several small online press release services, claiming that they infringed on their patented method of generating a press release online. The independent defendants attempted to fight back, pointing out a number of prior art examples on the web from before the patent was ever filed.
