Appeal No. 1999-2765 Page 10
Application No. 08/752,396
After the scope and content of the prior art are
determined, the differences between the prior art and the
claims at issue are to be ascertained. Graham v. John Deere
Co., 383 U.S. 1, 17-18, 148 USPQ 459, 467 (1966).
Based on our analysis and review of Hunts and claim 1, it
is our opinion that the only differences are as follows: (1) a
plurality of fittings, and (2) the complementary coupling
means for mounting of the fittings on the at least one wall
element.
With regard to these differences, it is our opinion that
it would have been obvious at the time the invention was made
to a person having ordinary skill in the art to provide the
construction system of Hunts with perforations in the floor
and wall panels to mount furnishings, transverse beams or the
like as suggested and taught by Heilig for the self-evident
advantages thereof (e.g., securing the furnishings and
transverse beams in position in a doll house).
