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.
While copyrights grow old, die and fall into the public domain, trademark rights can continue indefinitely if there is continuous use, and the mark (shorthand for trademark) is not permitted to lose its trademark significant by becoming a generic term. Even the tests for copyright and trademark infringement differ.
