Application No. 10/429,429
Thus, it is our perception that the appellants' claimed
reaction mixture includes any reaction mixture which produces, at
least ultimately, a flexible polyurethane foam. It follows that
the claim feature under consideration includes Eling's reaction
mixture. Moreover, contrary to the appellants' contention in
their Brief and Reply Brief, this claim interpretation is not
inconsistent with the subject specification.
For example, the specification discloses in the last full
sentence on page 7 that "[t]he flexible polyurethane foam
compositions . . . according to the present invention include all
well known, industrial compositions" (emphasis added). Use of
the term "all" supports the proposition that the aforementioned
industrial compositions include the compositions of Eling.
Additionally, in the sentence bridging pages 7 and 8 of the
specification, the appellants disclose that "flexible
polyurethane foam compositions can be made according to the
present invention by reacting an isocyanate with a polyol in
the presence of a foam-forming agent and a blend of tetra-
halophthalate esters and phosphorus-containing flame retardant
additives." Because these enumerated ingredients correspond
fully to those taught by Eling, the claim interpretation
