Your rights in a trademark continue as long as you use the mark. Federal registrations are valid for ten years, but they may be renewed over and over, so long as you are still using the mark in interstate commerce. The oldest continuously registered mark dates back to the 1870's.
If confidentiality can be maintained, the idea is likely a valid trade secret. Advantage #2: Trade secret protection can last indefinitely. While patents generally last up to 20 years, and copyrights generally last up to 100 years, a trade secret can potentially last forever. As long as the trade secret remains secret, the protection will not expire.
