Appeal No. 1997-1063
Application No. 08/414,702
those included in the claimed formula and a partially
fluorinated polyolefin having a number average molecular
weight of 30,000 to 1,000,000 selected from a list of the
specifically claimed partially fluorinated polyolefins. The
types and amounts of the block copolymer carbonates and
partially fluorinated polyolefins employed are such that the
claimed thermoplastic molding composition must have a flame
retardant rating of V-0 in accordance with UL-94 @ 1/8",
without the addition of any additional flame retarding agents
and other agents which may have an impact on the flame
retardant property. Thus, the claimed thermoplastic molding
composition is limited to only those which exhibit an
unexpected flame retardant property as shown in the example at
page 7 of the specification.
As evidence of obviousness of the claimed subject matter
under 35 U.S.C. § 103, the examiner relies on the combined
disclosures of Mark and Paul. However, we find that neither
of these references recognizes the importance of using
specific combinations of specific block copolycarbonates and
specific partially fluorinated polyolefins to obtain a
thermoplastic molding composition having an unexpected flame
