The Citizen Media Law Project has launched what looks like it could be a fantastic new resource: the Legal Threats Database. They plan to chronicle “lawsuits, cease & desist letters, subpoenas, and other legal threats directed at those who engage in online speech” and allow users to “view, search, and comment on entries in the database.” This initiative should build nicely on the work done by the Chilling Effects project (which, like CMLP, was incubated at the Berkman Center). And they have a blog to go with it too! My research on fair use in trademark law indicates that cases resolved by a judge or jury are a very tiny and very unrepresentative sliver of overall disputes about expressive uses of trademarks. The data collected here helps to document the many less visible disputes that end much earlier, with either settlements or surrenders.
