Excellent overview. This was my impression too after reading the patent documents on PAIR. Basically, the PTO was fully aware of Mori but granted the LDL-C point based on unmet need. PTO basically decided prima facie obviousness was sort of a rabbit hole for the LDL-C issue, and used long felt unmet need as the decisive test. The justification for reversing this weighing seems purely based on a whim, and without any new prior art/facts, is definitely out of line with presumption of validity for the PTO.
The Apo-B point ,too, is well qualified by the PTO. I believe the examiner stated prior art "is either silent" or does not teach of statistically sig reduction, which is a tacit reference to Kurabayashi. On this point, our smoking gun is of course Judge Du's by now infamous "statistically significant differential effects".
I honestly don't think this appeal needs to be any more complicated than this. But I suppose throwing in the procedural error couldn't hurt. I hope the Federal Circuit sees that the intense battleground for LDL-C prima facie obviousness is just affirmation of the examiner's view of that it's a pointless direction.
