German software giant SAP conceded Thursday that it allowed or even contributed to a subsidiary's effort to pirate software from archrival Oracle, while SAP lawyers renewed their complaint to a judge that Oracle is turning the case into a "sideshow" and "media circus." Redwood City-based Oracle hailed the concession as a significant development, as both sides gear up for a civil trial next week in Oakland federal court. SAP said it was attempting to narrow the focus of the trial, but Oracle attorneys said they will oppose SAP's move to limit testimony about SAP executives' role in the case.
