Appeal 2006-3208
Application 10/097,232
10. Li discloses a solid conveyor lubricant composition deposited on
a bottle in Fig. 1 (identical to Appellants’ Fig. 1) (Li, col. 2, ll. 15-19; col. 2,
ll. 55-58).
11. Li teaches the “lubricant coating should be sufficiently thick to
provide the desired degree of lubrication, and sufficiently thin to permit
economical operation and to discourage drip formation” (col. 5, ll. 45-48).
12. Li further teaches: “The lubricant coating thickness preferably is
maintained at at least about 0.0001 mm, more preferably about 0.001 to
about 2 mm, and most preferably about 0.005 to about 0.5 mm” (col. 5, ll.
48-51); these ranges are identical to those sought by Appellants (Spec. 11-
12).
Findings of Fact: Singlet Oxygen-Generating Agents
13. Goodrich discloses the value of photosensitizers “for inactivation
of microorganisms in fluids or on surfaces,” including “food preparation
surfaces” (Abstract).
14. Goodrich recognizes that some photosensitizers use “singlet
oxygen-dependent mechanisms” (col. 5, ll. 46-47).
15. Goodrich’s photosensitizers include many of those disclosed and
claimed by Appellants, for example, “methylene blue, acridine, toluidines
[and] coumarins” (col. 5, ll. 36-40).
16. Alder discloses additional dyes which are “[s]uitable sensitizers
for producing singlet oxygen,” including xanthene dyes, thiazines
(methylene blue), porphyrins (tetraphenylporphyrin), eosine and
benzophenones (col. 5, ll. 44-54).
