A trademark lawyer's most useful work is often before you file: checking whether your name is clear to use. Registration is with the US Patent and Trademark Office and isn't quick, so plan ahead of a launch. Be cautious of official-looking letters asking you to pay renewal fees, since scam notices are common.

Often many months or more, depending on the USPTO's backlog and whether it raises objections. Check the agency's current processing times, and don't count on a registration by a fixed launch date.
You can get some rights from using a mark in commerce, but federal registration adds important advantages, including nationwide priority and a stronger position in disputes.
Don't ignore it, and don't respond right away without advice. A lawyer can assess whether the claim has merit and whether a rebrand, coexistence agreement or response makes sense.
