On the ???s of patentabilities Targeting was obvious IMHO. Anexin V does that, but wasn't that only to see the PS for Apoptosis reasons...just measuring PS exposure. Targeting to effect PS signaling pathways is the new and important part. I HOPE! ALSO, the ~30 hour duration of the binding affinity is new. Correct? Is this a viable angle for patentability in your professional opinion? wook
