Appeal No. 95-1641
Application No. 07/825,927
consistent with appellants’ acknowledgment at page 9 of the
Brief that it is known to be more desirable to produce larger
crystals as shown, e.g., by the Forsberg reference. With
respect to appellants' reliance on Ferguson’s statistical
analysis it is not relevant to the present situation inasmuch
as it does not take into consideration the effect of
controlling evaporation speed and/or using large seed
crystals. Note also that appellants improperly assume a
different mean crystal size than that claimed (0.53 mm rather
than 0.35 mm).
Appellants argue that the Yamauchi reference does not
teach a large scale process. See Brief, page 13. To
determine the meaning of “large scale”, we have consulted the
specification. Nowhere does the specification, however, define
the meaning of “large scale”. Accordingly, we have given it
the broadest reasonable meaning based on its ordinary usage.
See In re Paulsen, 30 F.3d 1475, 1479,31 USPQ2d 1671, 1674
(Fed. Cir. 1994); In re Zletz, 893 F.2d 319, 321, 13 USPQ2d
1320, 1321-22 (Fed. Cir. 1989). Having given the broadest
reasonable meaning to the phrase “large scale”, we agree with
