polyurethane urea matrix (Abstract). Hammar also teaches that
the disclosed dental articles may be made by liquid injection
molding an abrasive particle-liquid mixture (col. 8, lines 10-
29). The polishing tip [20] shown in Figure 2 does have
portions [22] and [28] which can be reasonably described as
“elongated.” However, we do not find
that the projecting section or portion [28] terminates in an
elongated working face.
Since each and every element of claim 1 is not found in
either Wiand or Hammar (RCA Corp. v. Applied Digital Data
Sys., Inc., supra), the references do not anticipate claim 1.
Therefore, we will not sustain the rejection of claim 1 under
35 U.S.C. § 102 based on Wiand or Hammar. Since claims 2, 8,
20 through 26, 30 and 31 are dependent on and include all
limitations of claim 1, it follows that we will also not
sustain the rejections of claims 2, 8, 20, 21, 26, 30 and 31
under 35 U.S.C. § 102 based on Wiand or the rejection of
claims 2, 20 through 25 and 31 under 35 U.S.C. § 102 based on
Hammar.

Claims 1 through 14, 20, 21 and 26 through 32 stand
