Appeal No. 1999-0997
Application No. 08/397,141
The examiner relies on the following reference:
Guillon et al. (Guillon) 4,492,686 Jan. 08, 1985
Claims 14-27 stand rejected under 35 U.S.C. § 102(b) as anticipated by
Guillon.
Claims 14-27 also stand rejected for obviousness-type double patenting
over claims 1 -7 of Guillon.
We reverse both rejections.
Background
Various cosmetic compositions are formulated as a dispersion of solid
pigment particles in a fatty binder. Specification, page 1, lines 7-13. The
preparation and use of such compositions , however, poses several problems,
including “the difficulty of obtaining stable dispersions, so as to apply, for
example to the skin, a regular make-up whose application is uniform and which
retains a good homogeneity.” Page 1, lines 36-39.
Appellants’ specification discloses that the properties of such
compositions are improved when the surfaces of the solid organic pigment
particles are coated with a cationic polymer before the particles are introduced
into the composition. Page 3, lines 1-7. Specifically, such compositions “hav[e]
good properties of stability and adhesion to the skin” and nails. Id.
The specification discloses that the particles can be coated with polymer
using any of several known methods. Pages 29-30. Whatever method is used,
