A discussion of the Ultramercial, LLC v. Wildtangent, Inc. litigation, where Ultramercial, LLC sued Wildtangent, Inc., Hulu, LLC and YouTube, LLC for infringing its patent covering a method for distributing content over the internet by allowing an internet user to view copyrighted material after viewing an advertisement rather than paying to view it. The main issue is whether the claimed invention is a practical application of an abstract idea, which is patent-eligible subject matter under Section 101 of the Patent Act, or is merely a patent-ineligible abstract idea.
