Appeal No. 1999-1903
Application No. 08/781,055
Furthermore, the examiner has failed to explain why one of ordinary skill in the art
would have been motivated to use Young’s PSA beads, as such, as polymer binder
particles in the composite structure taught by Braun, considering that the Young disclosure
only contemplates ultimate use of the PSA beads, as PSA materials are conventionally
used, in the form of a continuous extruded film or dissolved in a solvent system. In this
regard, we refer to Young at col. 8, ll. 40-59. Nowhere does Young suggest that a PSA
material be applied in microparticulate form to produce a composite article in which the
PSA material essentially retains its particulate character.
For the foregoing reasons, the decision of the examiner is reversed.
