Today, the USPTO issued interim guidance on patent subject matter eligibility. The guidance calls for a two-part analysis for claims directed to judicial exceptions (laws of nature, natural phenomenon, or abstract idea). For details, see here.
In DDR Holdings, LLC v. Hotels.com, L.P., the Federal Circuit held that the patents directed to systems and methods of generating a composite web page that combines visual elements of a host website with content of a third-party merchant were patent eligible subject matter. The court noted that the patents' asserted claims do not recite a mathematical algorithm, fundamental economic or longstanding commercial practice but rather address a business challenge. According to the majority, the claims do not merely recite a known business practice from the pre-Internet world but a solution to overcome a problem arising in the realm of computer networks.
