It you think that YouTube is no longer brought in the spotlights for copyright infringement, you're wrong because, at least once a week, the online video sharing service is sent to the judge. This week, Google's YouTube was sued by Cal IV Entertainment, a company that owns approximately 60 music hits hosted on the online video sharing service. The Tennessee-based firm accused Google of copyright infringement, sustaining that its clips are published on the page without their approval. Because YouTube is protected by the DMCA rule that sustains the service cannot be accused of infringement since the users are the ones who upload the clips, Cal IV sustained that YouTube didn't do anything to block the copyright infringement cases.

"YouTube has failed to adopt and reasonably implement a policy that provides for the termination of repeat-infringing YouTube subscribers and account holders. YouTube also fails to monitor works it previously been notified are being infringed," it is mentioned in the complaint according to Google Watch.

As you probably know, this is not the first time when the online video sharing service is sent to the judge as YouTube is probably the most popular product among the US judges. Although the product was acquired in October 2006 for $1.65 billion, the parent company Google didn't make impressive efforts to stop the copyright infringement complaints and improve the product with other functions.

Recently, YouTube recorded the most popular lawsuits after Viacom, the owner of MTV and Comedy Central accused Google for publishing videos without authorization. The case was quite interesting because Viacom demanded YouTube to remove approximately 100.000 clips from the page and, after the removal was started, it sued the service. Viacom demanded $1 billion in damages, saying that Google uploaded the clips without approval. YouTube is always sustaining that it cannot be accused because it is protected by the DMCA act.
