The Judge is not seeking a technical explanation from MNTA; rather, the Judge is making MNTA do the grunt work of finding legal precedents for MNTA’s interpretation of the patent claims at issue. That’s why the Judge’s Order in #msg-68232191 directs MNTA to produce a memorandum of law.
Along with your info about a Special Master, this also answers the question that Marthambles and I asked regarding a Judge's technical/scientific expertise in this kind of case.
