Appeal No. 2003-0256
Application No. 09/334,375
regarding the rejection of claims 1, 19 and 43, however, the
examiner has not established a prima facie case of obviousness of
using a transponder on an ink cartridge. The examiner,
therefore, has not set forth a prima facie case of obviousness of
using, in addition to Purcell’s transponder and memory on the
media roll holder, a second transponder and memory coupled to a
second consumable used by the printer as required by claims 8
and 26. Consequently, we reverse the rejection of these claims
and dependent claims 9, 10, 13, 16, 27, 28, 31 and 34.
Claims 6 and 50
Claim 6 requires a transponder coupled to a cleaning fluid
consumable, and claim 50 requires a transponder associated with a
container for waste material.
Mochizuki discloses an ink jet printer having a memory
circuit for storing data representing the quantity of waste ink
sucked by a suction pump from a recording head into a waste ink
tank (23) while the recording head is being cleaned by purging it
with ink (abstract; col. 2, lines 28-44).
The examiner argues that it would have been obvious to one
of ordinary skill in the art to use Mochizuki’s waste
ink/cleaning fluid consumable in Purcell’s ink jet printer to
clean the printhead nozzles to maintain print quality (answer,
