            CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

     We have issued our report dated December 13, 2003, accompanying the
financial statements and schedule included in the Annual Report on Form 10-K of
CopyTele, Inc. for the year ended October 31, 2003 which is incorporated by
reference in this Registration Statement. Our report, which expresses an
unqualified opinion, contains an explanatory paragraph that states CopyTele,
Inc. incurred a net loss during the year ended October 31, 2003, and, as of that
date, has an accumulated deficit, and among other factors raise substantial
doubt about its ability to continue as a going concern. The financial statements
do not include any adjustments that might result from the outcome of this
uncertainty. We consent to the incorporation by reference in the Registration
Statement of the aforementioned report and to the use of our name as it appears
under the caption "Experts."
