<Does anyone have any insight into which, if any, of the ITC companies no longer infringe?>
That would resolve the USITC complaint, but if they choose to circumvent 336 usage, their products will be at a significant performance disadvantage compared to those of MMP licensees. And in all likelihood they would still need to pay royalties for past infringement as part of any NDOC settlement or judgement.
=======================================
Exactly my point. The past transgressions would still be subject to litigation and potential license revenue but ITC can't embargo a non-infringing variant.
