Abandonment of a trademark occurs when the owner of the
trademark deliberately ceases to use the trademark for three or
more years, with no intention of using the trademark again in
the future. When a trademark is abandoned, the trademark owner
may no longer claim rights to the trademark. In effect, this
frees the trademark so that anyone else can use it without
recourse from the original trademark owner. Definition from
Nolo’s Plain-English Law Dictionary A situation in which
trademark rights are lost because the owner: does not use the
mark for an extended period of time with the intent not to
resume use; lets others use the mark without adequate
supervision; or allows the mark to become a generic term. (See
