bitcoin.org is owned by bitcoin developers.
bitcoin.com is owned by person/people who provide bitcoin services.
But who owns the "Bitcoin" brand?

Bitcoin is not a company,so the name Bitcoin can't be considered a brand.Bitcoin is a currency.Can the other currencies (fiat and crypto) be considered as brands?Nobody is talking about whether or not the US dollar is a brand or who owns the term euro,because it would sound absurd.
The altcoin fork scammers took advantage of this situation and made several "Bitcoin"(BCH,BSV,Bitcoingold,etc..) projects that aren't actually Bitcoin.We can't do anything about that.
I don't think that for protwcting trademark is relwvant that Bitcoin is a currency. Anything could be protected with trademark just needs to be registered as such. Although that depends on legal system of the country where you want to do it.
However, I don't think that Satoshi or someone else has registered and protected Bitcoin trademark.
