(CBS/AP) - Google CEO Larry Page is back on the witness stand in a San Francisco courtroom Wednesday. Oracle Corp. is calling him as a witness in its patent and copyright case against Google.
The dispute in federal court is over whether Google Inc. built its widely used Android software by improperly taking some of the technology from Java, a programming platform that Oracle Corp. now owns.
Page sported a suit and a tie, a departure from his usual casual attire.
Page testified briefly on Tuesday before the court recessed for the day. He's being questioned by David Boies, the lawyer who went after Bill Gates in the federal government's antitrust lawsuit against Microsoft.
Here are key developments in that case:
Jan. 27, 2010: Oracle closes deal to buy Sun Microsystems and gets the Java computer programming language and related technology that is central to the lawsuit.
Aug. 12, 2010: Oracle sues Google in U.S. District Court in San Francisco. Oracle says Google's Android system for mobile phones infringes on its patented Java technology.
Sept. 12, 2011: The CEOs of both companies are ordered to attend a court-supervised attempt to settle a lawsuit. The attend sessions on Sept. 19 and 21 with no settlement reached.
March 27, 2012: In a joint statement, the two companies indicate they are far apart of key matters. Oracle is seeking hundreds of millions in damages, while Google believes it won't have to pay more than a few million dollars.
Monday: Trial begins. In opening statements, Oracle says Google's top executives have long known that they stole a key piece of technology to build Android.
Tuesday: Google's opening statements frame the case as Oracle's response to its own failure to build mobile software. Oracle CEO Larry Ellison admits under questioning by Google that Oracle wanted to compete with Android before deciding instead to sue Google.
The trial is expected to last up to 10 weeks.
