Federal Appeals Court Tosses Spam Patent

Zordak writes: Dennis Crouch's Patently-O is running a news item about U.S. patent 6,631,400, which has claims drawn to a method of making sure enough people get your spam. A federal district court had overturned the patent as anticipated, obvious, and not drawn to patentable subject matter. The Federal Circuit, the appeals court which hears patent matters, upheld the finding of obviousness, thus invalidating the patent.
