Oracle Corp. filed a wide-ranging lawsuit against SAP AG, alleging spying and "corporate theft on a grand scale."

Oracle claims that SAP employees used login information for Oracle customers to illegally access confidential material on Oracle's customer support Web site.

Oracle and SAP are in a long running rivalry. This lawsuit marks a new high point.

Oracle just posted great numbers for the 3rd Quarter. The profit rose 35%, due to a surge in business-software applications sales. I guess Larry Ellison decided he can afford now to sue SAP.

More details can be found on the Oracle site, where the company posted the full complaint. See also the WSJ (Subscription).
