Last year Sears asked Rockhard to stop using Diehard with the DieHard spray, and Rockhard agreed and abandoned its pending federal trademark application. However, it continued to distribute and sell the product.
Sears is claiming trademark infringement under likelihood of confusion and dilution theories. Hopefully, the judge won’t die laughing. One comment about the case already online said “assault on battery.” The jokes will no doubt continue.
My take is that Sears may have a credible dilution claim in the form of tarnishment. What do you think?
