v. Genentech Inc., 927 F.2d 1565, 1576, 18 USPQ2d 1001, 1010
(Fed. Cir. 1991).
The appellants’ claim 33 requires “restricting the flow
of the chemical compound into a portion of the reaction
chamber so that the flow is introduced towards the member”.
Harada discloses a method for removing N F impurity from
2 2
NF gas by heating the gas in a vessel which has a layer of
3
nickel fluoride on its inner wall and may be packed with a
solid fluoride (col. 2, line 49 - col. 3, line 8; col. 5, line
47 - col. 6, line 7). Harada teaches that neither the shape
of the vessel nor the method for heating it is particularly
limited (col. 3, lines 14-33).
The examiner considers Harada’s wall/bed to be the
component which corresponds to the appellants’ member (answer,
page 3). The examiner argues that Harada’s gas feed pipe
restricts the flow because the pipe has a finite diameter, and
further argues that the gas is fed into a portion of the
reaction chamber because the flow does not uniformly flood
