Patent Hawk is owned and operated by the sharp-minded (and sharper tongued) Gary Odom. The Hawk is a full-service IP consultancy, with a particular expertise in invalidity search on behalf of defendants in infringement cases. Gary's blog, the Patent Prospector, is hilarious, insightful, and informative. He focuses on patent litigation, with the occasional smattering of news and views on the USPTO or developments in patent policy. Every single post he writes is interesting -- there is nothing dry. If you like the Patent Prospector, you should also take a look at Infringement Updates and Docket Report.
