plate 350 (specification, p. 7, ll. 31-34 and p. 8, ll. 10-12).
In each case, at the inlet, fluid flows from a passageway outside
of the plate to a passageway within the plate and at the outlet,
fluid flows from a passageway within the plate to passageway
outside the plate.
Chen does not describe a plurality of inlets, inner
passageways, and outlets in a lower plate of a shower head as
claimed. In the shower head of Chen, as explained by Appellants,
the passageway 56 of Chen is a single inner passage connecting
one inlet hole 66 and one outlet hole 68. Passageway 56 does
not, at multiple locations extend outside the plate, it is at all
times conveying fluid within the plate. Openings 58 and 62 shown
in Figure 6 are not inlets and outlets within the meaning of
Appellants’ claims because these “openings” are closed off by
ring 64 that is inserted into groove 60. This ring is in place
in the shower head structure of Chen. Once the ring 64 is
inserted, there is one continuous serpentine passage 56 formed in
the plate (electrode 12). Fluid neither enters nor exits the
plate through the closed off openings 58 and 62, the fluid
remains within the plate.
