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.

Riddle me this, was Stargate SG-1 and family a space opera.

I inclined to believe so. I miss shows like that, we need more space operas

This makes me wonder if omegaverse (if you don’t know, don’t know) is trademarked given its litigious history.

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

I wonder if the trademark could actually be enforced.

The colour purple is trademarked, for chocolate. That just means you can't use Cadbury purple as the color for your chocolate wrappers. You can still use it for anything else. You can't make a game called Cyberpunk but you can use it for anything else.

Who owns the trademark on that?
