Google and Oracle will soon face off in court after a pretrial conference failed to reach a settlement.

The disagreement focuses on the Android operating system and Oracle's Java technology. The origins of the case stem from August 2010 when Oracle filed a lawsuit against Google, claiming Android mobile technology infringes on Oracle's Java patents, according to news reports.

Oracle acquired the Java programming language when it purchased Sun Microsystems, reports added.

The Wall Street Journal reported a recent attempt was made to iron out the dispute between Google and Oracle.

"Despite their diligent efforts and those of their able counsel, the parties have reached an irreconcilable impasse in their settlement discussions," U.S. Magistrate Judge Paul Grewal told WSJ. "No further conferences shall be convened. The parties should instead direct their attention to the preparation of their trial presentations. Good luck," Grewal said.

One rejected settlement proposal would have had Google giving Oracle a percentage of future revenues related to Oracle patents, the source said.

The trial is expected to begin later this month. Both companies are expected to appear April 16 before the U.S. District Court in San Francisco.

ZDNet reports the trial was expected to have started in October 2011 and then in March 2012 – but was delayed both times.

Oracle seeks hundreds of millions of dollars in damages, according to TechZone360. Oracle said it had about $1.16 billion worth of damages from Google’s alleged infringement of Java technology found in the Android OS, TechZone360 reported last September.
