carranza, All applications filed prior to June 1995 are 17 years from date of patent. All application filed after June 1995 are 20 years from date of filing. therefore, a portion of Qualcomm's patent portfolio will start to expire from 2007 to 2009. There are many, many other patents which build on the basic ones, but I don't have the technical background to say without qualification that they are unassailable or otherwise impossible to avoid. Commentary from those in the know on this point is welcome. Absolutely. Qualcomm was extremely intelligent to file for patents based upon their initial research and, in addition to receiving patents, those patents were both "broad" and "valid". At times, for many patent holders, the words "broad" and "valid" are mutually exclusive.
