A few months back we reported that Oracle was hunting for Google’s blood in patent infringement suit based around the latter’s Android mobile software. Well, now it seems that shy and retiring Oracle boss, Larry Ellison and his minions are moving in for the kill.

Larry Ellison and co smell blood

The company has updated its patent infringement suit with the enterprise software corporation directly accusing the search giant of copying its Java code.

The original suit was sort of light on detail, but this time around it includes specific examples of code that Oracle claims Google had half-inched to use in Android, with examples thoughtfully attached. These include class libraries and documentation.

Apparently Oracle charges that “approximately one-third” of the Android API packages are “derivative” of Oracle’s Java APIs. It even claims that “in at least several instances, Android computer program code also was directly copied from copyrighted Oracle America code.”

Google hasn’t said anything on the latest suit. As The Register points out, Oracle lawyers are pretty busy at the moment, what with this case alongside an ongoing spat with SAP, alleging the German firm copied Oracle trade secrets, a case which is due to be heard next week.

As The Register article adds, “The SAP spat has also further inflamed Oracle boss Larry Ellison’s testy relations with HP. Former SAP boss Leo Apotheker replaced Mark Hurd as HP CEO after the latter left in the wake of an expenses brouhaha. Hurd subsequently joined Oracle. Apotheker may, or may not, be called to testify at the court case. In the meantime, HP chairman and ex-Oracle president Ray Lane has defended his CEO, drawing further ire from Ellison.”

The Google case though, is the big one for most people. With Android now wildly popular, if Google has stepped on Oracle’s toes here expect them to pay pretty highly for it.
