Google CEO Larry Page returned to the witness stand Wednesday in Oracle's patent and copyright case against the Internet search leader over its popular Android operating system for phones and tablet computers.

Page sported a suit and a tie, a departure from his usual casual attire. The Oracle lawyer questioning him was David Boies, who had gone after Bill Gates in the federal government's antitrust lawsuit against Microsoft Corp.

Page testified briefly on Tuesday as Oracle's witness before the court recessed for the day.

The dispute in U.S. District Court in San Francisco 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.

On Tuesday, Oracle CEO Larry Ellison acknowledged he wanted to compete against Android in the smartphone market before deciding instead to sue his potential rival for copyright and patent infringement.

Google sought in opening statements to frame the case as Oracle's response to its own failure to build mobile software.

Android now powers more than 300 million smartphones and tablet computers.

The trial began Monday and was expected to last up to 10 weeks.
