Business software giant Oracle claimed Monday that it has new proof that its German rival SAP looted its software libraries for competitive advantage.

Oracle formally amended the civil suit it filed against SAP in the US District Court in San Francisco in March of 2007, enhancing its accusations with information gleaned during the case’s evidentiary phase.

“Oracle has now obtained SAP’s internal records, which confirm that SAP spent years systematically taking unauthorized support materials from Oracle’s systems,” lawyers for the California firm said in the revised complaint.

Oracle says in court documents that SAP used a customized software tool dubbed “Titan” to plunder Oracle’s website of patches, updates, fixes and other programs crafted for Oracle’s paying customers.

Titan and other tools were used to pack SAP data vaults with more than five terabytes of proprietary Oracle software, according to the revised complaint.

Oracle says it found nearly eight million Oracle programs on just one SAP computer. Oracle says it has proof that SAP executives not only knew of the online theft but endorsed the tactic.
