Appeal No. 2002-0552
Application No. 09/117,603
appellant's invention is directed to the use of a specific
sealant material, i.e., tar, which appellant has found to be
simpler and more reliable than prior art sealants and which does
not impair the suitability of the electrical leads for soldering.
In the paragraph bridging pages 3-4 of the specification,
appellant notes that the tar used can be "roofing tar" and that
such tar is fluid at normal ambient temperatures, spreads out
easily and forms a circular ring which seals the terminals (4)
and lead (3) completely against the wall of the housing,
penetrates by capillary action into any small voids between the
conductors and the feedthrough openings of the housing and into
crevices and cracks, and when dry, forms a solid sealed
connection between the terminal/conductor and the wall of the
housing, without impairing the suitability of the electrical
leads for soldering. A copy of claim 3 can be found in the
Appendix to appellant's brief.
The prior art references of record relied upon by the
examiner in rejecting claim 3 are:
Suzuki et al. (Suzuki) 5,637,007 Jun. 10, 1997
Arnett et al. (Arnett) 5,942,333 Aug. 24, 1999
Claim 3 stands rejected under 35 U.S.C. § 103(a) as being
unpatentable over Suzuki in view of Arnett.
