No, because doing so is against ICANN rules, so the maximum value of a brand domain is the cost to open an ICANN dispute.

Most likely the registry won’t let you buy trademarked domains if you can’t prove you have the trademark. There is a period set aside for tm holders.

I would stay far away from any brand or tm domains at any time. You will eventually lose the domain through a udrp. And you could likely get sued as well.

Only if both the company and the registry give enough of a shit. For example, microsoft.ba has been sqatted since 2006.

Despite Microsoft having a presence in the country, they still can't get .ba thanks to an incompetent registry in charge of .ba TLDs.
