AND INTERFERENCES

Ex parte PETER PFEUFFER
__________
Appeal No. 2001-0344
Application 08/900,254
__________
Before PAK, OWENS and MOORE, Administrative Patent Judges.
MOORE, Administrative Patent Judge.
DECISION ON APPEAL
This appeal was taken from the examiner's decision rejecting claims 1 through 4,
which are all of the claims pending in the application. Claims 5-8 have been canceled.
THE INVENTION
The invention relates to a method of manufacturing a pleated filter material.1 In
short, the claims recite the one-step calendering and bonding of a non-woven material
1 The preamble of claim 1, a method claim, was amended by the Applicants’ representative pursuant to
an Interview initiated by the Examiner on May 3, 2000 to recite “pleated” filter material. We note that there
appears to be an apparent misapprehension of the terms “pleat” and “spacer” as argued in the Reply
brief. If further proceedings are conducted, we would suggest that the Appellant and the Examiner should
revisit this issue and establish more fully on the record the reasons for the amendment.
