Appeal No. 2001-1773
Application No. 08/732,864 Page 2
BACKGROUND
Appellants' invention relates to a method and apparatus for
drop weight encoding. An understanding of the invention can be
derived from a reading of exemplary claim 1, which is reproduced
as follows:
1. An inkjet print cartridge for use in an inkjet printing
apparatus for forming images on print media, the inkjet print
cartridge comprising:
a pen body;
an inkjet printhead mounted to the pen body for ejecting ink
drops onto print media, the inkjet printhead having a
manufacturing tolerance associated therewith and producing a
corresponding actual drop weight for said printhead which is
dependent on the manufacturing tolerance in a range of drop
weights; and
an information storage device supported by the pen body and
associated with the inkjet printhead for storing information for
identifying said corresponding actual drop weight for said
printhead, said information readable by the inkjet printing
apparatus.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Watrobski et al. 5,504,507 Apr. 2, 1996
(Watrobski) (effectively filed Oct. 8, 1992)
Bullock et al. 5,699,091 Dec. 16, 1997
(Bullock) (filed Jan. 8, 1996)
Claims 1-11 stand rejected under 35 U.S.C. § 103 as being
unpatentable over Bullock in view of Watrobski.
