HP's Bid to Block Hurd's Oracle Move Is Long Shot, Lawyers Say - Bloomberg
Mark Hurd, former CEO of HP has joined Oracle as co-president. HP is very unhappy about that, trying to get some money back.
At the same time Oracle is suing Google for using Java language, but not Java VM and platform in Android for mobile phones and other devices.
A Brief Introduction to the Java and .NET Patent Issues
There is many former Java people now working in Google, and Java is heavily used in Google, so Oracle has a chance to get some money this way...
Oracle could even get some money from HP for their implementation of Java VM called Chai, that is used in many HP devices...
The flow of money would be : web => Google => Oracle => HP :)
