US patent office supports Tzero, rejects Pulse~LINK patent

While it was Pulse~LINK winning the last (but obviously not final) round of this multi-year tiff, the tables have turned once more. Tzero Technologies has just announced that the US Patent Office "issued an office action rejecting all claims of US patent number 6,970,448 asserted in a lawsuit brought by Pulse~LINK against Tzero in June 2007." This decision, coupled with a stay issued by the district court, will evidently bring the lawsuit to a close "for the foreseeable future." We're told that the legal struggles between the two are now officially over, but we're admittedly hesitant to believe it.
