Appeal No. 97-4056 Page 6
Application No. 08/238,926
781, 789 (Fed. Cir. 1983), cert. denied, 465 U.S. 1026 (1984), it
is only necessary for the claims to "'read on' something
disclosed in the reference, i.e., all limitations of the claim
are found in the reference, or 'fully met' by it."
We agree with the examiner that claim 20 "reads on" Parker
and therefore Parker does anticipate claim 20. We read claim 20
on Parker as follows: In a harbor (Parker's bay or harbor 2)
having an entrance (Parker's strait 3) between the harbor and an
open sea area (Parker's sea 4), the entrance being sufficiently
unobstructed to permit free and continuous tidal propagation
therethrough (the appellant admits on page 19, lines 37-39, of
the brief that the tide propagates through Havana Harbor as a
wave), a system for cleansing the harbor (Parker's canal or2
waterway 7 and head-producing mechanism 8) comprising: a conduit
(Parker's canal or waterway 7) having first and second openings;
said first opening placed within said harbor (Parker's canal or
waterway 7 communicates with the upper end 5 of the bay or harbor
2 and thus inherently has an outlet opening at the harbor end of
2Additionally, Parker specifies (page 1, lines 22-26) that
harbors of the class specified have a narrow entrance or strait
into which drives at regular intervals the tide from the sea, of
which a portion with equal regularity recedes.
