Legal Question in Business Law in Washington

Yes, technically you can register in another state a company with the same name as a corporation owns in one state.

Yes, you'll have to worry, possibly big-time, about losing actions in trademark infringement (under state and federal laws), unfair trade practices (state law), unfair competition (state law) and bad faith dealings (state law). There may be further actions filed for misappropriation (state and federal laws). You'll also have to worry about the original corporation expanding into your state.

You need to speak (not this freebie forum; actually go to an attorney and pay for the time) with an attorney in your state who handles formation and trademark issues in your state if you really want to go this route.
