Question

Quizplus · Accepted Answer

A trademark that is not used for an extended period of time can be considered abandoned and lose its protection under federal law. The length of non-use required for abandonment may vary depending on the circumstances, but generally, it must be shown that the owner is no longer using the mark and has no intention of using it again in the future.
