The jury delivered its verdict after more than a week of deliberations. It found no infringement of any of the claims in two Java-related patents Oracle had asserted in its lawsuit against Google, show.

The verdict brings to an end a closely watched trial that has captivated Silicon Valley since it began on April 16. The jury had already returned an inconclusive verdict in the copyright phase of the trial, and the finding of no patent infringement meant the jury had no need to calculate damages for Oracle and could be dismissed.

However, the legal battle between the two companies is not over. There may yet be a new trial to hear the part of the copyright verdict on which the jury was undecided and both parties seem sure to appeal any final outcome that goes against them.

But for now, Oracle leaves the courtroom with a tiny fraction of the billions of dollars in damages it was seeking when it originally filed its lawsuit.

Oracle sued Google in August 2010, arguing that its Android OS infringes Java-related patents and copyrights that Oracle acquired when it bought Sun Microsystems two years ago. The trial was to be held in three phases, to address patents, copyrights and damages, and has seen the CEOs of both companies take the witness stand.
