The reason for that is due to WWE failing to comply with a documentation request.
Fast forward to March 12th, the USPTO denied WWE’s request due to them needing written consent from Lesnar and there were issues with some of the verbiage in the filing.
WWE was later given six months to get written consent from Lesnar and that was not provided. As a result, on September 15th, the filing was abandoned and confirmed via correspondence to the company on October 10th.
Lesnar is no longer under contract with WWE and he’s a free agent. His last contract ended at WrestleMania 36, which is when he was last seen in action as he dropped the Universal Title to Drew McIntyre. His merchandise contract expired in August.
