obviousness decision-Takeda v. Alphapharm

An interesting decision regarding obviousness post KSR.
Alphapharm challenged Takeda's patent pre KSR saying it was obvious, but lost.
They appealed after KSR and still couldn't get a reversal.
It's an interesting read, they talk about both KSR and Pfizer v. Apotex (another case that was recently decided).
EDIT:  Here's the link:

The decision is what I expected after KSR.   They went through Graham and ended trying to find some motivation or suggestion.   They didnt find it because there were "negative effects" associated with compound b, among other things.  
It does illustrate the importance of prosecution history, however, I am not sure why the court did not give deference to the PH verses the Sodha reference.  In one respect, it was written as "especially important" and Sodha, the compound was evidenced as teaching away.
"the court found that any suggestion to select compound b was essentially negated by the disclosure of the Sodha II reference."
they state "given the more exhaustive and reliable scientific analysis presented by Sodha II."
I guess "especially important" really was not qualified and is a generally weak statement, and Sodha II was a scientific publication?
