Google Inc. is facing a copyright infringement lawsuit relating to a documentary video that appeared on Google Video, reports Reuters.

The recent lawsuit is a potential harbinger for more legal actions against the portal since it purchased popular video-sharing site YouTube last month for $1.65 billion.

"This is a small lawsuit over a single video that appeared briefly," Google spokesman Ricardo Reyes said in a statement. "We have procedures in place that allow copyright owners to tell us if their content is placed on Google Video without authorization. When we receive appropriate notice, we quickly remove the content from Google Video."

Industry analysts predict that YouTube will be faced with more lawsuits now that its pockets are a part of Google's bank account.

Recently, YouTube made several content deals with major media companies such as Viacom and NBC, but it is still facing some copyright issues.
