Application No. 10/392,140
Wenning from being offset welded, and we decline to read
limitations into the claim that are not found therein.
Appellants may be correct that in Wenning, the welding of the
outer housing could conceivably harm the insulation. However, we
have relied upon the inner housing of Wennings to meet the
limitations of claim 10, and have alternatively relied upon the
outer housing. In any event, appellants do not argue the
teachings of Just. From the disclosure of Just of using a butt
weld to secure the facing edges of a sink that is fabricated out
of metal using seamless weld (col. 1, lines 7 and 8 and 36 and
37), we agree with the examiner that an artisan would have been
motivated to weld facing elements in the structure of Wennings.
From all of the above, we find that the teachings of the
prior art would have suggested the limitations of claim 12. The
rejection of claim 12 under 35 U.S.C. § 103(a) is sustained.
