Caleb Williams' 'Iceman' trademark denied due to boot liner

Chicago Bears quarterback Caleb Williams' attempt to trademark "Iceman" has been refused by the USPTO. The refusal cited a "likelihood of confusion" with an existing 1988 trademark held by LaCrosse Footwear for insulated boots and boot liners, noting the marks are identical in appearance, sound, and meaning. Williams had sought the trademark across various categories, including clothing, athletic bags, and entertainment services.
