The latest instance of Apple suing a publication over rumors is the case of ThinkSecret, an Apple rumor site run by a Harvard student. Apple sued the site and its owner on January 4 over info the site published about Apple's recent (then upcoming) product announcements. Now, ThinkSecret has retained the services of Terry Gross, the lawyer who served as the first counsel to the EFF.
This challenge to Apple's legal threats is important because it will tackle Apple's claims on two fronts. The first is the obvious First Amendment argument, but the second may be even more important: the question of the protection of trade secrets under California law. Apple has been using the trade secrets issue as part of its legal threats for some time now. If the trade secrets issue doesn't work, or if First Amendment concerns override it, Apple may have to curb its litigious ways.
