I think the CF Litigation could well be TPL's attempt to support that the CF portfolio is worth more than PTSC has argued in their court filings, thus reducing TPL's exposure in the event there are settlements in the future where TPL has to reimburse PTSC for comingled discounted MMP licenses that have been signed in the past.

See l2007s post regarding the Apple license for example. If TPL assigned 5% to MMP and 50% to CF, then getting a settlement with an infringer on CF that is more in line with what they charged Apple would help TPL argue that the percentage values applied were accurate.
