If you needed a crown or root canal lately, your dentist may have used a fancy wand to scan and send a picture of your mouth to the dental lab. Chances are that the scanner was the Itero Element scanner, a computer scanning system that is manufactured by Align Technologies. The Itero scanner requires a disposable sleeve for the wand. One of Align’s competitors, Strauss Diamond Technologies, began selling a competing sleeve, called “MagicSleeve”. In its advertisements, Strauss used Align’s trademarks in hashtags, product descriptions and product images.

Using someone’s trademarks when criticizing their products or services can be tricky. But if you do it the right way, it could be considered nominative fair use.

A press release doesn’t always amount to trademark use. %CUT% In the 1980s, Toni Basil had a one hit wonder “Mickey” that included the lyrics, “You’re so fine you blow my mind, Hey Mickey”. She sold the copyright to the recording of the song. When Disney Co., Kohl’s and Forever 21 started using the song in their advertising, they issued press releases and mentioned Toni’s name in connection with the song. Toni sued for various types of Intellectual Property infringement including trademark infringement based on the press releases. Toni argued that the use of her name violated trademark law based on false designation of origin. The judge disagreed and dismissed the trademark claim holding that the use of her name in the press releases as nominative fair use.
