HP was furious when Oracle snapped up Mark Hurd, the wining and dining ex-CEO, meanwhile Oracle claims to be just as furious claiming in a filing today that HP's hiding its plans for Apotheker was "deliberate and active concealment" of material facts. Or so says the Wall Street Journal.
The whole thing has been going on for months now, with a lot of legal footwork and name-calling on both sides. Oracle has been publicly publishing statements accusing HP of slowing down Itanium's death, following on from when Oracle ditched it earlier this year. HP was angry at that and sued. Since, it's been tit for tat."
