Oracle confronts Google's Schmidt about Java

Google's former CEO told jurors that he was confident that the Android smartphone platform was developed legally, and that top executives at Sun Microsystems did not object to the project now at the center of a high-stakes court battle.

Eric Schmidt, now Google's executive chairman, took the stand on Tuesday in the trial of Oracle against Google over smartphone technology.

Oracle , which acquired Sun in 2010, sued Google in August 2010, saying Android infringed on its copyrights and patents for the Java programming language. Google countered that it does not violate Oracle's patents and that Oracle cannot copyright certain parts of Java, an open-source, or publicly available, software language.

In court on Tuesday, Oracle attorney David Boies showed Schmidt a 2005 presentation to Google's top managers that said Google "must" take a license from Sun. Schmidt said he could not recall being told that was the case.
