Bears' Caleb Williams' 'Iceman' Trademark Application Initially Refused by USPTO

Chicago Bears quarterback Caleb Williams' attempt to trademark his "Iceman" nickname has hit a snag.

Per ESPN's Michael Rothstein, the United States Patent and Trademark Office has initially refused Williams' application for "Iceman."

However, the USPTO made its decision due to the similarity and a "likelihood of confusion" in a trademark filed in 1988 by LaCrosse Footwear for insulated boots, not because of an application for the nickname by NBA Hall of Famer George Gervin or a trademark possessed by UFC Hall of Famer Chuck Liddell.

"These marks are identical in appearance, sound and meaning," the USPTO wrote in its refusal letter. "…Additionally, because they are identical, these marks are likely to engender the same connotation and overall commercial impression when considered in connection with applicant's and registrant's respective goods and/or services."

In addition to clothing, Williams applied for trademarks for athletic bags, water bottles, sporting goods, a website and entertainment services. His trademark application of an Iceman logo, separate from the word, remains under initial review with the USPTO. He can appeal the initial ruling.

Gervin, who also shared the nickname, is attempting to trademark "Iceman" and "Iceman 44." His applications are still under review with the USPTO, but he could face the same roadblock as Williams.
