Close but no cigar
They are speaking to the wrong guys. R&D would rather take his life than betray Samsung or his management, the other stooges are STA, which had nothing to do with the decision to copy Apple. STA are just marketing.
They should start with the senior Product Management team in Korea, who made the call (yes, they did) with JK. But again, these guys would rather be shot than betray their companies/management/families/country, even for a US court, so this, sadly, won't go anywhere.
