Collaborative Filtering

I/P engine sued Google, Target, and Gannett (a media conglomerate) over 6,314,420 & continuation 6,775,664. Judge and jury at district court found the patents infringed, and neither anticipated nor obvious. As these were major U.S. corporations, there was no way that those decisions would be upheld on appeal. Sure enough. The CAFC panel majority agreed with Google that "as a matter of law [the claimed invention] simply combines content-based and collaborative filtering, two information filtering methods that were well-known in the art." To rub it in the noses of unreasonable citizens who waste their time on jury duty: "no reasonable jury could conclude otherwise." In concurrence, Judge Mayer thought the claims "fall outside the ambit of 35 U.S.C. ยง 101."
