Patent Troll Tracker: This blog rocks! Troll Tracker is an anonymous blogger, probably a patent lawyer, that reports over abusive patent claims and litigation. The posts are well cited with links to court docs. There is a current bounty out on the Tracker's identity. A powerfully patent attorney , and alleged Troll, Ray Niro is offering $5k to anyone who unearths his identity. I strongly recommend this blog,
Wa Patents: This is a local Seattle blog run by Mark Walters a patent attorney at Darby & Darby. The content is interesting, recent and especially relevant to patent geeks in Washington. I respect the authors knowledge and depth of treatment on local and nation patent issues even though I do not agree with his economic and political arguments. I recommend this blog especially to people with an interest in local patent issues.
Copyfight: This is a team blog with some impressive names in copyright law including Donna Wentworth of the Berkman Center and Wendy Seltzer of of Northeastern University School of Law. The articles are a bit on the academic side, but very well researched and cited. The only downside is that the authors seem to post in cycles and I can not tell which authors are still active or have gone elsewhere to blog.
