these teachings, one of ordinary skill in the art would have
found it obvious to provide the modified apparatus of the

wall of the chamber for independently controlling the position
of the shutters from outside of the chamber. Suggestion for
such is found in the self-evident advantages of providing this
type of control, such as being able to change the positions of
the shutters without the necessity to stop the process and
gain access to the interior of the chamber, which would have
been known to one of ordinary skill in the art, skill being
presumed on the part of the artisan, rather than the lack
thereof. See In re Sovish, 769 F.2d 738, 743, 226 USPQ 771,
774 (Fed. Cir. 1985).
