@epimer my stepdad has thought of an amazing name for a common device. Can he register this in some way in order to extract money from the manufacturer in order to use this name?
He could apply for a trade mark and try to sell/license them that, but unless he’s selling the item himself they’ll probably tell him to fuck off.
Consult a trade mark attorney for more info. You can find one on the CITMA website.
Paypal is fine.
From what I understand of trademark law. All you need to do is add tm to the end of the name.
