Farhad Manjoo gives us some good news in the wars against patent trolls:

When companies are sued for patent infringement, or when they’re proactively protecting themselves from an infringement claim, they often hire a prior art search firm to look for related inventions. But such searches tend to be expensive—you usually need to hire researchers in many different countries—and not all that effective, because even professional searchers tend to miss a lot of stuff. More than a decade ago, a young patent attorney named Cheryl Milone had a flash of insight for solving this problem: “I wondered, instead of looking for a needle in a haystack, what if you could ask each piece of hay if it’s a needle?” That might sound like some kind of riddle, but Milone’s insight has transformed patent litigation. In 2008, she founded Article One Partners, a firm that invites amateurs to look for prior art and rewards successful researchers with cash.

From Threat Level, we learn about a big business called Righthaven picking on little people and non-profit organizations who run blogs. If you are running a blog, there are two options. A) Register as a DMCA takedown agent with the U.S. Copyright Office (which I am now in the process of doing) or B) Prepare to travel to Las Vegas federal court to defend yourself against this copyright troll, based (usually) on a commenter's use of copyright material. Here's an excerpt from the Threat Level article:

Founded in March, the Las Vegas-based Righthaven has begun buying out the copyrights to newspaper content of the Las Vegas Review-Journal for the sole purpose of suing blogs and websites that re-post, or even excerpt, those articles without permission. The company has settled about 60 of 160 cases for a few thousand dollars each, and plans to expand its operations to other newspapers across the country. Many of its lawsuits arise, not from articles posted by a website’s proprietors, but from comments and forum posts by the site’s readers.
