‘410 or Tachikawa II for reasons which follow.
OPINION
A. The Rejection over Tachikawa I
The process of appealed claim 1 requires reacting the
three components (a), (b) and (c) of the Ziegler-Natta
catalyst system “wherein, after the reaction, the reaction
mixture is deactivated by reaction with carbon dioxide.” In
proceedings before the PTO, claims in an application are to be
given their broadest reason-able interpretation consistent
