As another commenter hinted at, "Thinkpad" used to mean IBM laptop; Lenovo bought the name (and PC division of IBM) for that reason, and they don't mind if people think they're still IBM, because OG Thinkpads were the bomb. This is what I was getting at.
It's bananas that the IBM association is just gone now, because the name was huge in the 90s. Sometimes a fella can really feel old.
