Supreme Court weighs in on Jack Daniel's dog toy trademark dispute.

The Supreme Court heard arguments on Wednesday in a case involving Jack Daniel's and the makers of a dog toy that mimics the whiskey's signature bottle. The question for the court is whether the toy's maker infringed on Jack Daniel's trademarks. The justices were largely on their best behavior, not picking up on the toy's poop humor and puns. At the heart of the case is the Lanham Act, the country's major trademark law. Jack Daniel's says the dog toy misleads customers and profits "from Jack Daniel's hard-earned goodwill" and associates its "whiskey with excrement."
