https://www.law.cornell.edu/wex/abandonment_(of_trademark)> 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.
