Appeal No. 96-0515
Application 08/169,081
bottom surface of substrate member 102 is bonded to the upper
surface of a nozzle plate 104 by an adhesive 106, which is
advantageously selected to be a polymer material such as one
of the polymer materials sold by E.I. Dupont's under the trade
names RISTON and VACREL (col. 3, lines 47-52). The material
of which substrate member 102 is formed is not disclosed. The
substrate member includes passages 108, 110, and 112 for
allowing ink to pass from ink chambers 88, 90, and 92 in pen
body 10 to the orifices in the nozzle plate (col. 3, lines 52-
58).
In comparing the claims to Baker, the examiner reads the
claimed cartridge on pen body 10, the claimed printhead on
nozzle plate 104, and the claimed "member" having a slot
therethrough on substrate member 102, having passages 108,
110, and 112 (final Office action at 4). The examiner
concedes that Baker's substrate member is not described as
being porous or flexible or as containing a thermal setting
adhesive in its pores (id.). For these teachings, the
examiner turns to Kneezel, which discloses a method of
providing inkjet printheads with ink filters by laminating a
substantially flat wafer-size filter to an ink inlet wafer or
