`harmonically related tones,” in Journal of the Audio
`Engineering Society, vol. 24, no. 7, pp. 568-571
`(Sept. 1976) (“Cabot”), and in further view of PCT

`Obviousness under 35 U.S.C. § 103 over Srinivasan,
`in view of Cabot, and in further view of Kudumakis

`Obviousness under 35 U.S.C. § 103 over
`Kudumakis, in view of John F. Tilki et al.,
`“Encoding a hidden auxiliary channel onto a digital
