Oracle is in the same boat with Javascript. Technically they own the trademark. But world+dog has been using that trademark freely without them doing anything about it. So, their claims to the trademark are weak at this point.

And, yet, it seems to still be difficult to do anything about it, with Deno now raising $200k to fight it. Ultimately, someone still needs deep enough pockets to push the point even if the legal point seems straightforward.
