Appeal 2006-3208
Application 10/097,232
4. Commercial lubricants in the form of powders were also available
at the time the invention was made (Spec. 9-10 (“Preferred commercially
available lubricants include . . . the EVERGLIDE™ and ULTRAGLIDE™
series of micronized wax powders . . . available from Shamrock
Technologies Inc; and the . . . series of micronized waxes” and “micronized
fluorocarbon available from Micro Powders Inc.”)).
5. Li’s “lubricant compositions preferably have a coefficient of
friction (COF) that is less than about 0.14, more preferably less than about
0.1” (col. 4, ll. 40-44).
6. Li’s “lubricant composition can . . . be applied to a wide variety of
containers including beverage containers,” and the containers “can be made
of a wide variety of materials including . . . PET” (polyethylene
terephthalate) (col. 4, ll. 52-59).
7. Surfactants “often are employed in conveyor lubricants” (Li, col. 4,
ll. 15-18); and antimicrobials may be added to the lubricants (Li, col. 4, ll.
24-32).
8. In fact, Li discloses and claims compositions containing
surfactants, such as sorbitan esters (col. 3, ll. 10-13; col. 10, ll. 45-47).
9. Li is using a “phase-separating mixture of a hydrophilic lubricating
material and an oleophilic lubricating material,” the reference discourages
the use of certain surfactants to help avoid “[f]ormation of an unstable
mixture and promotion of early phase separation” (claim 6; col. 4, ll. 15-18);
however, such a teaching would not discourage the skilled artisan from
using surfactants generally, particularly in other conveyor lubricants (FFs 5,
6).
