Discussion
Claims 15-17, 19, 22-30, 50-52, and 70-83 stand rejected

pp. 6-7, bridging para., repeated verbatim at pp. 7-8,
bridging para., through p. 9, first full para.):
Zaffaroni discloses nonnutritive flavor imparting
compounds of the general formula (F-Z)n-C wherein F is an
active flavor imparting agent, C is a controlling agent
for transporting and essentially restricting absorption
of the compound (F-Z)n-C in a biological environment, Z
is a covalent bond for bonding F to C and n is at least
one. Zaffaroni discloses that the group C include
