Appeal 2007-0666
Application 09/738,992
A. INVENTION
The invention at issue on appeal "provides a collaborative annotation
technique in which users can make handwritten annotations to original paper
documents." (Specification 2.) According to the technique, each user
employs a device to capture a digital image of a paper document including
any handwritten annotations thereon. The image is processed to extract
images corresponding to the annotations, and the extracted images are
distributed to the other users for display. Each user may, therefore, view a
combined image of the document on which the individual annotations are
overlaid. Because users prefer to handle, and to make annotations on, a
paper document rather than on an electronic representation thereof, assert the
Appellants, theirs is "the most convenient technique for a user." (Id.)
B. CLAIM
