Appeal 2007-1666
Application 10/132,904
1. Yin discloses four embodiments of a guard structure 4, and each has a
composite material component associated with it as identified in
Figs. 2, 3, 4, and 5 as elements 24, 36, 46, and 52, respectively. We read the
composite material component 24, 36, 46, and 52 in the guard structure 4 of
Yin as the guard. The guard composite material in each of the four
embodiments of Yin is disclosed as comprised of a matrix of a water-
insoluble polymer and, dispersed within the matrix, a skin lubricating water-
soluble polymer, thereby making it a substantially uniform mixture and
integrally formed via the polymer matrix (Yin, col. 4, ll. 14-20).
2. The guards 24 and 36 in Yin, as illustrated in two embodiments, are attached
to the frame by adhesive (Yin, col. 3, ll. 18, 29; Figs. 2 and 3).
3. Yin discloses a frame or housing 10 to which one or more blades 2, 3 are
attached (Yin, col. 2, ll. 55-60).
4. We find that the cartridge 10 in Yin is capable of functioning as claimed
because a user can tilt the cartridge so that the integrally formed and
substantially uniform mixture, and not the flexible fins 26, 38, 48, 58,
engage the user’s skin first.
5. Yin discloses that the “flexible fins 26, 38, 48, 58 engage the user’s skin
first” (Yin, col. 5, ll. 8-9).
6. Yin discloses that the fins function only to: 1. stretch the skin to “pull on the
shaving stubble” (Yin, col. 5, ll., 9, 10), 2. act as a squeegee (Yin. col. 5, l.
13), and 3. provide a pleasant tactile sensation (Yin col. 5, ll. 14, 15).
