Timing of the Yamaha deal

Based on the Mattis book, the article says the patent was licensed to Yamaha in 1974. A web page at Stanford says Yamaha took the license in 1973 instead: https://ccrma.stanford.edu/people/john-chowning . But the only patent Chowning holds was filed in 1975 as a continuation-in-part of an earlier application filed in March 26, 1974, which was abandoned. https://www.google.com/patents/US4018121

So this raises a couple of questions: when did Yamaha actually make this deal, and did the company actually take the license based solely on a pending patent application? That happens sometimes, but is unusual especially for such ground-breaking ideas.

Maybe someone has better sources of information. 76.22.118.146 (talk) 00:00, 10 March 2017 (UTC)[reply]

Also, various sources say Stanford has earned x amount of money on its 1971 patent FM Sound Synthesis. But the work seems to have been completed around 1973-74. So I wonder what is the title of the actually patent making the money, and who is the assignee - possibly of Stanford and not Chowning? Jonpatterns (talk) 14:44, 15 December 2017 (UTC)[reply]

From the Frequency modulation synthesis article:

The technique of the digital implementation of frequency modulation, which was developed by John Chowning (Chowning 1973, cited in Dodge & Jerse 1997, p. 115) at Stanford University in 1967–68, was patented in 1975. Prior to that, the FM synthesis algorithm was licensed to Japanese company Yamaha in 1973.[1]

The reference is a book, so the answer may be contained within: Chowning, John; Bristow, David (1986). FM Theory & Applications - By Musicians For Musicians. Tokyo: Yamaha. ISBN 4-636-17482-8.
