Greg, I made my first QCOM purchases in 1992. You are right that QCOM did not invent CDMA. Most of the work on CDMA was done by its predecessor company, Linkabit, headed by Jacobs and Viterbi, to whom most of the early key CDMA patents were assigned. Linkabit was sold to Interdigital Communications, whereupon Jacobs and Viterbi and their colleagues organized QUALCOMM as a private company, taking it public in 1991. Jacobs literally wrote the book on CDMA, and in fact, his 1964 textbook which deals in part with CDMA remains the standard in the field. While Jacobs and Viterbi are focused on a very specific sector of telecommunications, in contrast to Edison, whose focus ranged from electrical power generation to acoustic reproduction, the potential benefits stemming from Jacobs and Viterbi are so great that ranking them with Edison is a credit to all three.
