Google is confident that they are protected by the law in the Google vs. Viacom lawsuit. Google says that they are protected by copyright law because they have done everything that was required of them. From the article:
Viacom said that by the time it filed the lawsuit, it had identified over 150,000 clips on YouTube that infringed its copyright and asked for them to be taken down. Viacom also argued that YouTube's reliance on rights-holders to notify it of cases of infringement places an unfair burden on them.Wait! It's unfair to Viacom that they have to notify YouTube? It's unfair that YouTube is 100% responsible for monitoring the thousands of videos uploaded every day. It's not as if Google is a pain to work with; they remove all the clips that they are sent notices for. What are they complaining about?
