The thing with trademarks is that someone generally has to own the trademark. Since no individual or company owns Bitcoin, there's no one to legally enforce a trademark. It's unlikely the community would ever accept or generally be comfortable with any single person having that much power or influence over Bitcoin's name. Bitcoin's code is released as open source and free for anyone to modify as they see fit. There's nothing in the licensing that specifically states users can't use the name "Bitcoin" in their forks.

Here's the full wording:

Code:

The key words being "without restriction" and "without limitation", providing they include the copyright notices. BCH devs have included those in Bitcoin ABC, albeit from earlier dates. So yeah, the usual 'I-am-not-a-lawyer' disclaimer applies, but I can't see they have anything to worry about in terms of infringement.

I hear you and understand what you're saying. That said, I have some stipulations to make here without getting into too much legality.

First of all, I'm talking about trademark law, not copyright. The second half of what you said is all related to copyrights. In general, copyrights are meant to protect the original product or work and all forms of distribution/re-distribution of it. Trademarks are meant to protect consumers from the source of the good, product, or service.

Second, regarding the registration - there is still common law trademark law, at least in the United States. By virtue of having a product or service that is well-known, you have legally protected rights to that trademark.

And yes, of course the same legal disclaimer exists from my side as well. Thanks for the response!
