There is a long-running dispute between Thompson-Reuters and Ross. TR alleges that Ross used the Westlaw headnotes to train a competing AI product. In 2023, Judge Bibas largely ruled against TR. But on the eve of trial, the case was stayed. Today, Judge Bibas issued a revised opinion. In short, he changed his mind.
The opinion begins:
A smart man knows when he is right; a wise man knows when he is wrong. Wisdom does not always find me, so I try to embrace it when it does––even if it comes late, as it did here. I thus revise my 2023 summary judgment opinion and order in this case.
