To clarify, use of the original "right tilted", "orange" #Bitcoin #BTC logo continues unhindered 'as-is' in the public domain."
I don't get it. If the logo is in the public domain, then how can its use be restricted?
I maintain Threshold of Originality over the current Bitcoin BTC logo / design concept, as a proven originator of the logo design.
I can therefore apply (and legally enforce) Trademarks in jurisdictions.
I am not sure that is correct. My understanding is that a trademark holder can take action to prevent someone from confusing potential customers into thinking a product is similar to the trademark holder's brand.
So if Dell were to sell a Dell computer named "Mac", then Apple could sue Dell for trademark infringement because Dell is confusing potential customers as to the brand of computers being sold. There may be the potential to extend that concept to a logo. However the entity bringing the action needs to be the trademark holder, not the creator of the name or the logo.
