While cases like the scan-to-email trolls make the news, it&#x27;s precisely because they are relatively rare. Tech media likes to hype these up and make it seem like there&#x27;s a rash of these cases, studies by the GAO and a couple of scholars indicate that there is actually no patent troll crisis. While it&#x27;s true that we have insufficient insight into the numbers for demand letters, there are very few other <i>reported</i> entities actually doing this. That said, I&#x27;d still like to see lot accountability and tracking of demand letters.
