c|net - A corporate shoving match has begun between Hewlett-Packard and Dell following new allegations that HP robbed Dell of trade secrets. Fortune magazine reported this week that it unearthed information that appears to support claims made by Karl Kamb Jr., a former HP vice president. Kamb said in legal documents filed in January that in 2002 HP paid a former Dell executive to snatch trade secrets about Dell's printer business. After the story, a Dell spokesman said HP had yet to respond to requests that the company investigate Kamb's accusations. HP is suing Kamb for allegedly stealing some of its technology.
