Appeal No. 95-4300
Application No. 08/165,565
BACKGROUND
At pages 1-2 of the specification, applicants describe the invention as relating to a
flame resistant thermoplastic composition comprising a blend of aromatic brominated
polycarbonate, polyester carbonate and silicone polyimide which may optionally comprise
an unsubstituted aromatic polycarbonate. Applicants describe improvements in flame
resistance, drippage and heat release rate obtained by adding a metal salt of a
monomeric or polymeric halogenated aromatic sulfonic acid, a filler or pigment to the
composition.
GROUPING OF THE CLAIMS
At page 3 of the Appeal Brief (Brief), appellants indicate that all claims stand or fall
together. Therefore, we will limit our consideration of the rejections in this appeal as they
apply to claim 1, as representative of claims 2-13 and 16-17. While appellants have not
separately argued claim 15 in either the Brief or the Reply Brief, we note that the claim was
amended June 26, 1995, at the time of filing of the Reply Brief, in response to a new
ground of rejection and other comments made by the examiner in the Examiner's Answer
of April 26, 1995 (Answer). Claim 15, now before us on appeal differs from the claim 15
pending at the time of appellants' statement concerning the grouping of the claims on
appeal. We elect to separately consider claim 15.
