WASHINGTON: The Supreme Court ruled on Thursday that the First Amendment did not protect a chew toy for dogs resembling a bottle of Jack Daniel’s from a lawsuit claiming trademark infringement.

The toy, the Bad Spaniels Silly Squeaker, has the shape and other distinctive features of a bottle of Jack Daniel’s but with, as an appeals court judge put it, “light-hearted, dog-related alterations.”

The words “Old No. 7 Brand Tennessee Sour Mash Whiskey” on the bottle are replaced on the toy by “the Old No. 2, on your Tennessee carpet.” Where Jack Daniel’s says its product is 40 percent alcohol by volume, Bad Spaniels’ is said to be “43 percent poo.” A tag attached to the toy says it is “not affiliated with Jack Daniel Distillery.”

Justice Elena Kagan, writing for a unanimous court, seemed amused by the dispute. “This case is about dog toys and whiskey,” she wrote, “two items seldom appearing in the same sentence.”

She added that the characteristics of the whiskey bottle were familiar to almost everyone.

“A bottle of Jack Daniel’s — no, Jack Daniel’s Old No. 7 Tennessee Sour Mash Whiskey — boasts a fair number of trademarks,” she wrote. “Recall what the bottle looks like (or better yet, retrieve a bottle from wherever you keep liquor; it’s probably there).”

After reproducing a color photograph of the bottle, she continued: “‘Jack Daniel’s’ is a registered trademark, as is ‘Old No. 7.’ So too the arched Jack Daniel’s logo. And the stylized label with filigree (i.e., twirling white lines). Finally, what might be thought of as the platform for all those marks — the whiskey’s distinctive square bottle — is itself registered.”
