THE TESTIMONY: Oracle CEO Larry Ellison says the company wanted to compete against Google's Android software before deciding instead to sue his potential rival for copyright and patent infringement.

WHAT HAPPENED: Ellison says the company explored it and "decided it was a bad idea."

ABOUT THE CASE: It's the second day of a trial pitting two high-tech bellwethers. The dispute is over whether Google built its widely used Android software by improperly taking some of the technology from Java, now owned by Oracle.
