Public Citizen is one of several consumer, arts, and public interest groups that have sent a letter to the Senate Judiciary Committee, condemning recent changes in trademark protection that make it a lot easier for people to get sued for what was previously "fair-use".
The specific issue is referred to as "trademark dilution"; as written, the new law could've let (for example) Chevrolet sue Don McLean for singing "drove my Chevy to the levee", or Dave Thomas sue Walter Mondale for using Wendy's phrase "Where's the beef?" Ludicrous. As Atrios points out, trademark law was originally intended to protect people from being confused and ripped off by shoddy imitators with similar brand names and logos, not to protect the sanctity of a brand.
