Appeal No. 1998-0863
Application 08/502,831
Patton WH-80, under 35 U.S.C. § 103.
(2) Claims 16 to 20, unpatentable over Krichton in view of
Kuwabara, either of Chaney or Schindler, and further in view
of Patton WH-80, under 35 U.S.C. § 103.
Rejection (1)
Claim 11 reads:
11. In an upright radiant electric heating appliance
comprising a reflector assembly having rear surfaces, a
radiant heating element assembly extending vertically adjacent
to said reflector assembly, a housing extending around the
rear surfaces of said reflector assembly, and a top cap
mounted on the upper end of said housing above said reflector
assembly, the improvement wherein said top cap is formed from
a molded thermoplastic material.
Krichton discloses an electric heater having a reflector
assembly 174, a vertically extending radiant heating assembly
186 adjacent to the reflector assembly, a housing 22 extending
around the rear surfaces of the reflector assembly, and a top
cap 26. The housing is disclosed as being made of sheet metal
(col. 2, line 14), and as appellants state at page 21 of the
brief, “the invention of claim 11 differs from [Krichton] only
in the use of molded thermoplastic material to form the top
cap.”
