Appeal No. 1999-2114
Application 08/821,711
193 USPQ 332, 335 (CCPA 1977). See also In re Chitayat, 408
F.2d
475, 478, 161 USPQ 224, 226 (CCPA 1969) (the court held that
arguments based on mere measurements in drawings are of little
value without the relative dimensions set forth in the
specification) and In re Wilson, 312 F.2d 449, 454, 136 USPQ
188, 192 (CCPA 1963) (the court held that patent drawings are
not working drawings). Moreover, page 2, lines 11-17, of BPS
‘215 indicate that “[a]fter final compression, the cover plate
7 and the upper plunger 4 are moved to positions which permit
the finish-pressed blank 1 to be ejected from the mould 2 by
further upward movement of the lower plunger 3 . . . ."
(emphasis added). There is no indication in BPS ‘215 that the
cover plate is moved during completion of final compression or
while the full force necessary for compression is maintained
against the particulate material. Like appellant, we consider
the examiner’s position that BPS ‘215 shows a clear teaching,
as evidenced by Figures 1 and 2, of sliding movement of gate 7
while the force is exerted by lower plunger 3 against the
8
