There are several systems attached to domain names and trademarks. If the company name is registered, even without a trademark, your national domain registrars will usually award the domain to you. This is somewhat more complex in the USA, where each State runs its own registry of company names. Trademarking helps there, as that is a national assertion of the right to use a name.
If your business is trademarked, then you should be able to claim the .com, .net. etc forms from the domain registrar. It sometimes takes a while. Part of the process is to contact the previous/current owner and ask them why the domain shouldn't be released to the trademark owner.
When you have the trademark for the business, Google will generally allow the assertion of the right to use the trademark in advertising. They'll even help with reasonable variations, especially if you are a large business. So if "Windows" is trademarked, then Google might allow protecting "VVindovvs" or even "Wimdows".
However, Google *doesn't* trademark protect the Display URL. They have another policy for that. The final site reached using the Destination URL must match the Display URL. That is, if you advertise the Display URL of XYZ.com, then the Destination URL can start by taking you to "redirection.com", but that site must *immediately* redirect you (301 or 302) to another site, for example, another-redirect.com, which must similarly immediately redirect (301 or 302), and so on - until you end up at a site where the highest part matches. So you could take people to "sales.XYZ.com" or "www.XYZ.com" or "store.XYZ.com".
Don't pay for an expensive TM lawyer if you already have the TM. The Google TM protection process is free, but grinds fairly slowly. Months rather than days, to get the protection. Once granted, protection is swift. hours rather than months.
