"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." Did the application of that rule change? At one time the "whichever is later" rule only applied for application/issue dates during a transition period, 1995 to 1998, as I recall. Older patents expired 17 years after the issue date ... period. Newer patents expired 20 years after the application date ... period. If it didn't change, the last expiration date for those five foundational patents is Apr 28, 2009.
