to activate any and all computer functions that might be
incorporated in a pen-based computer system" (Br13). It is
argued that Sklarew discloses softkeys which can be used to
enter computer commands with a non-gesture action and,
"[t]hus, the mere existence of references showing pen-based
computers which can recognize gestures, does not automatically
suggest to one of skill in the art that implementing a text
domain conversion on such computers would necessarily involve
a pen-based gesture" (Br13). There are a limited number of
ways for a user to enter data and commands in a pen-based
system, e.g., a keyboard, softkeys, or gestures. One of
ordinary skill in the art of designing interfaces for pen-
based computers would have considered any of these known
methods, e.g., a gesture, to have been obvious. The existence
of a limited choice of options does not make the selection of
a particular option nonobvious.
Appellant argues that "Sklarew's handwriting recognition
process involves text from only a single text domain" (Br15)
and that "handwritten text and computer text from the same
character set do not constitute separate source and
destination text domains within the meaning of the claimed
