forming each individual pixel by activating said
switchable elements such that each individual pixel is formed
by a plurality of said switchable elements and the intensity
of each said pixel is controlled by the amount of time said
switchable elements are in an ON state.
No references were relied on by the examiner.
Claims 15 and 17 stand rejected under the first paragraph
of 35 U.S.C. § 112 for lack of written description. According
to the examiner (Answer, pages 3 and 4):
Claims 15 and 17 claim that each pixel is formed
[by] a plurality of individual elements. This claim
is not supported by the specification because at
page 20 last paragraph a pixel is described as being
represented by a 4 by 4 matrix of individual
elements which are driven at the same time depending
upon the result of the interpolation processing,
however, this portion of the specification does not
describe controlling the number of "ON" elements in
the 4 by 4 matrix where the number is based upon a
desired gray scale level for that particular pixel.
The specification describing figures 5a to 5c (pages
23-25) describe gray scale control of pixels, but,
this description is silent as to controlling
individual elements of a pixel to control the gray
scale of that pixel. Various other embodiments are
present in this applicantion [sic, application],
but, none of them support claims 15 and 17.
Appellants argue (Brief, pages 3 and 4) that:
As claimed in claims 15 and 17, the method and
apparatus merely combine using more than one element
of the array per pixel and control the amount of
time each element in the pixel is ON to achieve gray
scale for that pixel. The method of pulse width
modulation on page 23 is clearly stated as being
