Appeal No. 97-1609
Application 08/425,310
Upon consideration of applicant's BRIEF ON APPEAL
(Paper 18), the EXAMINER'S ANSWER (Paper 19) and the entire
record, it is
FOUND, on this record, that a person having ordinary
skill in the art would have believed that determination would
have been unpredictable as to which inorganic phosphorus
reagent might be suitable for use in the Jaquiss polyester-
polycarbonate composition for the purpose of neutralizing
residual catalyst remaining after the polyester and/or
polycarbonate is made (see Jaquiss, col. 3, Table 1) and it is
FURTHER FOUND, on this record, that as recently as
1990 the prior art reveals that "[a]n extensive search
[would have been necessary to find] *** a material useful for
stabilizing *** [residual] catalyst" remaining in polysiloxane
polymers (Beck, col. 3, line 60 to col. 4, line 1), and it is
STILL FURTHER FOUND, on this record, that the prior
art, as a whole, does not provide a sufficient teaching,
suggestion, reason or motivation to use any silylphosphate or
mixture of silylphosphates described by Beck and/or Petersen
for the purpose of neutralizing residual catalyst which may be
present in a polyester-polycarbonate compositions,
