Last year, the Supreme Court ordered the US Court of Appeals for the Federal Circuit to reconsider the validity of a patent that broadly covers the concept of Internet users watching advertisements in exchange for accessing copyrighted content.
US patent 7,346,545, titled "Method and system for payment of intellectual property royalties by interposed sponsor on behalf of consumer over a telecommunications network," was granted to a company called Ultramercial and used to sue Hulu, YouTube, and a gaming company called WildTangent. Hulu and YouTube were dismissed from the case, while WildTangent had to fight on. WildTangent challenged Ultramercial's "invention" as being too abstract to qualify for patent protection, and the company won a ruling from US District Court in Central California dismissing the patent lawsuit.
The appeals court reversed the district court decision and remanded the case to that court. But the Supreme Court vacated the appeals court ruling, saying the online ad patent should be re-examined in light of a previous Supreme Court decision, which invalidated a patent that broadly covered a method for determining the proper dose of a drug used to treat autoimmune disorders. So the question of whether the patent was valid went to the appeals court again.
In a decision Friday (PDF), the appeals court recognized that the Ultramercial patent doesn't specify a mechanism for implementing the ad system—but still refused to invalidate the patent on the grounds that it is too abstract. "This court understands that the broadly claimed method in the ’545 patent does not specify a particular mechanism for delivering media content to the consumer (i.e., FTP downloads, e-mail, or real-time streaming)," the court wrote. "This breadth and lack of specificity does not render the claimed subject matter impermissibly abstract. Assuming the patent provides sufficient disclosure to enable a person of ordinary skill in the art to practice the invention and to satisfy the written description requirement, the disclosure need not detail the particular instrumentalities for each step in the process."
