Bluetooth legalities

Update: I contacted the Bluetooth Alliance, took some time but got my answer: You must be a legal entity to register, for example an LLC, registered partnership, or a Corp. You MUST register if you want to use the word Bluetooth in commerce, or use the Bluetooth trademark (symbol). If you use a Bluetooth module, even if it’s already registered with them, such as all the Microchip modules, and you use it in your product you must pay a Declaration fee. First two are $2500 each. After that the price goes up to $4000. If the module uses GATT it’s another $100 on top. Just thought y’all would like to know!!
