I think the evidence clearly suggests that posters on this board identified the statistical problem which was the impetus for the paper. The statisticians did the heavy lifting and it appears Bhatt's name was added to give credibility and greater attention.
It's important to remember the original paper was an old paper and the original authors, peer reviewers and years of readers failed to find the error. To presume the Amarin lawyers would have foreseen it or even that that issues would be key in the decision is silly.
JT's error was not pursuing the Rule 60 expeditiously.
I see others have answered so I won't repeat - don't know how you pin all the blame on JT though - I blame Covington. And I still say Mori was a sideshow, Kura was the most important as far as patents go, and Du screwed that up bad - Covington couldn't respond, never knew about it until Du had issued her decision and the cropped table showed up.
