Appeal No. 2000-0526
Application No. 08/818,958
liquid is ejected out of said container" recited in patent
claim 13 to be a step of injecting the liquid, as required by
claim 3.
Claims 13 and 14 of the Farris I patent differ from the
method recited in claim 3 on appeal, in that (1) the patent
claims are directed to injection of "liquid" rather than
"therapeutic fluid," (2) the patent claims omit a step of
docking the syringe with a device at the fluid exit and (3)
the patent claims do not recite a step of "bending closed a
gas passageway . . . just prior to the injecting step."
Farris II, however, discloses the use of plungerless
syringes as medical devices for the injection of fluids to
patients (column 1, lines 11-14), teaches connecting a needle
34 or cannula 26 to the outlet portion of the syringe in a
manner allowing liquids in the container of the syringe to be
ejected through the needle or cannula (column 5, lines 65-68)
and, as discussed above, teaches compressing (i.e., bending)
the walls of a passage between a gas chamber and the container
of the syringe to form a seal to prevent gas which has passed
into the gas chamber from being injected into the patient.
