Hewlett-Packard may seek damages of $4 billion to $4.2 billion from Oracle in its lawsuit over support for Itanium server architecture. An economist that HP plans to call in the case made the estimate at an evidentiary hearing on Monday in Santa Clara County Superior Court in San Jose, California. The economist, Jonathan Orszag of the consulting firm Compass Lexecon, estimated the difference between HP's Itanium-related revenue with and without Oracle's March 2011 announcement that it would stop porting software to Itanium.
