Appeal No. 2004-1333
Application 09/969,190
As noted on page 1 of the specification, appellants’
invention lies in the field of vacuum-insulated walls and, more
particularly, thermally insulating walls, e.g., for refrigeration
appliances, with an evacuated inner space that is filled with
thermally insulating material that can be evacuated and that is
at least as far as possible surrounded, in a vacuum-tight manner,
by gas and water vapor impermeable inner and outer claddings
formed of thermoplastic material. Independent claims 1, 20 and 21
are representative of the subject matter on appeal and a copy of
those claims can be found in the Appendix to appellants’ brief.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Luetkens, Jr. et al. (Luetkens) 5,128,196 Jul. 7, 1992
Buckley 5,722,482 Mar. 3, 1998
Wynne WO 98/29309 Jul. 9, 1998
Claims 1, 11, 12, 20 and 21 stand rejected under 35 U.S.C.
§ 102(b) as being anticipated by Wynne.
