Bluetooth - Oops, I Just Violated Their Trademark

According to the Bluetooth brand requirements, the term "Bluetooth" must always be used as an adjective. Furthermore, when the term "Bluetooth" is used to denote the corresponding technology, the term "wireless" must be inserted between the Bluetooth and the terminology. Bluetooth is named after the Danish king Harald Blatand (meaning blue tooth). So basically, you cannot even refer to the word "Bluetooth," since doing so violates the spirit of the trademark; by that rule, it cannot even be listed in the dictionary.
