Appeal No. 2006-1411
Application No. 10/013,875
The examiner relies upon the following references as
evidence of obviousness:
Hansen et al. (Hansen) 3,855,046 Dec. 17, 1974
Cumbers 4,035,219 July 12, 1977
Sawyer et al. (Sawyer) 5,672,415 Sep. 30, 1997
Shultz et al. (Shultz) 6,103,647 Aug. 15, 2000
Appellant's claimed invention is directed to a method of
making a non-woven fabric. The method entails passing a fiber
web of polyethylene through a pair of rollers which thermally
bond the fabric. At least about 24 percent of the fabric area
is bonded by an engraved pattern on one of the rolls. The
engraved pattern on the roll has a plurality of bond points
having a bond point angle higher than 20°.
Appealed claims 1, 7-16, 18, 50, and 52-56 stand rejected
under 35 U.S.C. § 103(a) as being unpatentable over Hansen in
view of Cumbers, or Cumbers in view of Hansen. Claims 20-22
stand rejected under 35 U.S.C. § 103(a) as being unpatentable
over the stated combination of references further in view of
either Sawyer or Schultz.
Appellant submits at page 4 of the principal brief that
"[f]or purpose of this appeal only, the Appellant does not
assert that any claim in the group under the four grounds for
rejection should stand or fall separately" (last paragraph).
