Spangenberg lawyers want to dig into Google’s patent reform efforts

5 12 2008

Polaris IP, aka Bright Response, is an arm of Erich Spangenberg‘s patent-holding empire. In one of its lawsuits, filed August 2007, it targeted Google, Yahoo, AOL, and IAC/InterActiveCorp, accusing them of infringing U.S. Patent No. 6,411,947. This patent, which is on natural language processing, became somewhat infamous after it was targeted by EFF’s Patent Busting Project. EFF has the prosecution history of the patent on its web site. Spangenberg companies now own the entire interest in this patent.
