> OpenAI can't register OpenAI because they make ai but it's not open

That's not the reason they can't. They can't register the trademark because it's a descriptive one.

If I try to trademark "hacker forum", an EU trademark officer will reject it not because my website doesn't have hackers on it, but because it's descriptive and prevents others from starting hacker forums.

So

> They could call themselves... ClosedAI

is also incorrect, because it's descriptive as well.

>OpenAI can't register OpenAI because they make ai but it's not open.

Not the issue. Per the ruling even if their AI was open they still couldn't have the trademark.

Open could mean open to integration (API), or opens your mind, or opens possibilities.

No, the opinion doesn't have to do with whether OpenAI is open.
