Copyright and trademarks are different things. If they trademarked cyberpunk then it would probably come with a font, colour and style not just the word because the word is too generic. Apple were not allowed to sell music for a long while due to the trademark of apple music who did the beatles. Cadbury's have trademarked purple for chocolate and kit kat tried it on recently with trying to trademark two rows of chocolate bar next to one another. But you can use purple and make twin bar chocolate bars and you can talk about cyperpunk the genre and probably make cyberpunk products so long as the product is not confusing with that done by the trademark registrar.

It used to be the case the microsoft used to spam a lot of ads for "Word", just "Word" not "Word for Windows". Heck, even Windows is a generic term too. All of it has become daft since the age of search engines when you type in "word" into google and expect your product to be the top billing entry. Since there are 40 million cyberpunk entries on google then their product is going to be lost in the haystack.
