In I/P Engine v. AOL, 35 U.S.C. 101 was not addressed by the majority but a concurring opinion would have held the claims non-statutory in view of 35 U.S.C. 101. The claims were held invalid as obvious.
I/P Engine, Inc. brought an action against AOL Inc., Google Inc., IAC Search & Media, Inc., Gannett Company, Inc., and Target Corporation alleging infringement of U.S. Patent Nos. 6,314,420 and 6,775,664. A jury returned a verdict finding that all asserted claims were infringed and not anticipated.
The ’420 and ’664 patents both claim priority to the same parent patent, U.S. Patent No. 5,867,799. They relate to a method for filtering Internet search results that utilizes both content-based and collaborative filtering. Content-based filtering is a technique for determining relevance by extracting features such as text from an information item. By contrast, collaborative filtering assesses relevance based on feedback from other users—it looks to what items “other users with similar interests or needs found to be relevant.”
Apparatus claim 10 of the ’420 patent recites:
A search engine system comprising: a system for scanning a network to make a demand search for informons relevant to a query from an individual user; a content-based filter system for receiving the informons from the scanning system and for filtering the informons on the basis of applicable content profile data for relevance to the query; and a feedback system for receiving collaborative feedback data from system users relative to informons considered by such users; the filter system combining pertaining feedback data from the feedback system with the content profile data in filtering each informon for relevance to the query.
Apparatus claim 1 of the ’664 patent provides:
A search system comprising: a scanning system for searching for information relevant to a query associated with a first user in a plurality of users; a feedback system for receiving information found to be relevant to the query by other users; and a content-based filter system for combining the information from the feedback system with the information from the scanning system and for filtering the combined information for relevance to at least one of the query and the first user.
Claim 26 of the ’664 patent is similar to claim 1, but cast as a method claim:
A method for obtaining information relevant to a first user comprising: searching for information relevant to a query associated with a first user in a plurality of users; receiving information found to be relevant to the query by other users; combining the information found to be relevant to the query by other users with the searched information; and content-based filtering the combined information for relevance to at least one of the query and the first user.
The Google Defendants argued that I/P Engine’s claimed invention is obvious as a matter of law because it simply combines content-based and collaborative filtering, two information filtering methods that were well-known in the art. The Federal Circuit agreed and stated that no reasonable jury could conclude otherwise.
Just Mayer concurred, stating because the claims asserted by I/P Engine disclose no new technology, but instead simply recite the use of a generic computer to implement a well-known and widely-practiced technique for organizing information, they fall outside the ambit of 35 U.S.C. § 101. And if this determination had been made in the first instance as directed by the Supreme Court, litigation, and nearly two weeks of trial and imposition on citizen jurors, could have been avoided.
