Meanwhile, "cyberpunk" has been successfully trademarked in the US, even though it describes a literary genre. That's like someone trademarking "space opera", "romantasy", "film noir" etc.
Choose Your Own Adventure is also trademarked, though that trademark (initially held by Bantam books, lapsed, and re-registered by another company) did originate the name of the genre
Whatever else is real or myth with regard to these trolly pranking trademark spats, I think it's pretty reasonable to say that the term "cyberspace" emerged amidst - or at least adjacent to - a lot of LSD and Grateful Dead tapes.
