A lawsuit that accuses Google, Apple and other top Silicon Valley companies of driving down wages by agreeing not to hire each other's workers can go to trial, a judge has ruled. The case alleges that executives including former Apple CEO Steve Jobs and former Google CEO Eric Schmidt agreed not to poach the other's workers during a period between 2005 and 2009. The alleged agreements would violate state and federal antitrust laws. Adobe Systems and Intel are also named as defendants.
