discloses in the background of the invention that prior art
telephones include only small displays capable of displaying
information such as dialed numbers and that a need for
displaying a large amount of transmitted data at the telephone
has increased. Wells further discusses the problems
associated with incorporating full-size data displays. Wells
solves the prior art problems by providing a miniature virtual
image display which can display a full page of text (see
column 2, lines 42-46).
Wells uses for his display a line of light emitting
diodes (LEDs) and a magnifying optical system which "creates a
magnified virtual image of the LED line" (column 2, lines 47-
51). Wells then converts the virtual line image into a
virtual raster image by an oscillating mirror. Appellants
contend (Reply Brief, page 3) that Wells' vibrating mirror is
not a fixed optical system as is required by each of claims 1,
7, and 20. However, as described in the abstract, "[a]
