Rakitno: Apparently, it was confusing language to several.
Clarification from IDC:
As part of the agreements, which include the JV, Sony is licensing FROM InterDigital its patent portfolio covering 3G and 4G. InterDigital is not licensing anything from Sony.
Patrick Van de Wille apologized for the 'tough grammar' as to how it was worded.
Tried to get more info (Terms, fixed or variable, and length of license) but he didn't respond to those parts of my email.
Oh well, they still are tight-lipped at this time about their licenses.
