Viacom's $1 billion copyright lawsuit case against YouTube is reportedly heading towards a ruling.

According to All Things Digital, three years after the case started both parties have requested a meeting with the federal court judge to discuss their individual motions for summary judgement. If the summary judgement goes ahead, the judge rules without sending the case to trial.

Viacom accuses YouTube of encouraging copyright infringement, stating it is profiting when users upload unauthorized TV and movie clips.

According to All Things Digital, each company claims in their letter that the evidence proves their cases.

Viacom identified 63,000 unauthorised clips from films and TV shows on YouTube. Google claimed it is protected by the Digital Millennium Copyright Act (DMCA), which it says prevents it from being held responsible for copyright violations committed by users.
