Currently there is a house bill that would revise the Lanham Act's Trademark Dilution provisions. Historically, trademark infringement actions could only be brought when marks were confusingly similar to one another. In 1977 the federal trademark laws were amended to allow a cause of action for diluting a famous mark even when there was no likelihood of confusion. That means, if a mark is similar, even if the products are completely different, a junior mark that "whittles away" the distinctiveness of the senior mark is now infringing. This amendment was a huge expansion of trademark rights, and there was much concern of its chilling effects on free speech.
Well, now Congress is considering expanding the dilution statute even more. With its proposed revision, the senior mark holder doesn't even have to show damages in order to prove dilution. The proposed amendment is drafted in such a way that words, images, or even colors that look vaguely like a famous brand would be considered dilution. There is no doubt this chills free speech. As such the EFF is launching a campaign to prevent Congress from passing this bill.
