McAfee Granted Far-Reaching Spam-Control Patent

Titusdot Groan writes "Infoworld is reporting that Network Associates, makers of McAfee, have been granted a broad anti-spam patent. The patent covers "compound filters, paragraph hashing, and Bayes rules" and was filed in December of 2002. The patent appears to affect Spam Assassin, Spam Bayes and many other anti-spam products and services. As an aside Paul Graham's "A Plan for Spam" was published August 2002."
