Google says Oracle sued after own market failure

(AP) -- A Google lawyer is seeking to convince a jury that Oracle sued the search company for copyright infringement only after Oracle failed in its own attempts to build mobile software.

The depiction emerged Tuesday as Google lawyer Robert Van Nest framed the company's defense against Oracle Corp.'s allegations that Google Inc. stole some of the technology used in its Android software for smartphones and tablet computers. It marked the second day of a trial expected to last up to 10 weeks in a federal court in San Francisco.

After Google's opening arguments, Oracle called CEO Larry Ellison to the stand.

The showdown revolves around Oracle's allegations that Android infringes on the patents and copyrights of Java. That's a programming technology that Oracle acquired in 2010 when it bought Sun Microsystems.
