Appeal 20072907
Application 10644791
The Fujii publication
Fujii discloses a fire-retardant sealing agent.30 While epoxy resins
work well, they are insufficiently fire-retardant. Bromine and antimony are
commonly used fire-retardant additives, but they present safety concerns,
and phosphorous-based alternatives are unsatisfactory.31 Fujii's solution is a
fire-retardant epoxy resin that is free of bromine and antimony.32 Metal
oxides and hydrates could be used instead although they adversely affect the
material properties of the epoxy and the oxides might not be sufficiently fire
retardant. Fujii specifically names molybdenum trioxide (MoO3) as one
such metal oxide.33 Fujii uses a blend including magnesium hydroxide and
specific metal oxides.34 The specific metal oxides include oxides of zinc,
tin, molybdenum, and tungsten.35
DIFFERENCES BETWEEN THE PRIOR ART AND CLAIM 1
The Gallo patent does not teach or suggest the use of melamine
cyanurate.
Saito would anticipate the subject matter of claim 1 if Saito's
melamine/isocyanuric acid compound were melamine cyanurate as seems
likely in view of Yamaguchi's disclosure; otherwise, Saito lacks a teaching
of the use of melamine cyanurate.
Yamaguchi does not teach the use of a chromium-family metal oxide.
Fujii does not teach the use of melamine cyanurate.
