Using regexp's To Search IDS Data -- Patented

Posted by timothy on from the oh-sure dept.

MiniGhost writes "Well... the USPTO is at it again! A recent search of their online patent database reveals a new patent issued on Nov 26, 2002. Apparently cisco has been issued patent #6,487,666, titled 'Intrusion detection signature analysis using regular expressions and logical operators.' So now they are claiming patent rights on the use of regular expressions and logical operators for IDS usage. It's only a matter of time before some corporation patents the stick man now!!"

    I'm glad there are still people out there who evaluate the merits of patents based on reading them, rather than based merely on the titles. Bravo.

    You, sir, just made my friends list.
