The phrase "fully paid up" for expired licenses makes no sense to me.
I believe that this is a list of the five core patents that lie at the heart of Q's invention of CDMA. The expiration dates are either 17 years from issuance or 20 years from filing....whichever is later.
So, of these five patents, the first expired in '07, but the rest expire in '09 or '10. Nokia's license likely gave them a fully paid up status about 2 1/2 to 3 years early.
Kudos to Carranza back in '01 :-)....
