Exhibit 23.1
                                                                    ------------


            CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


We have issued our reports  dated January 11, 2007,  accompanying  the financial
statements and schedule,  and  management's  assessment of the  effectiveness of
internal  control  over  financial  reporting  included in the Annual  Report of
CopyTele,  Inc.  on Form 10-K for the year ended  October 31,  2006.  Our report
accompanying  the  financial   statements  and  schedule,   which  expresses  an
unqualified  opinion,  contains an explanatory  paragraph that states  CopyTele,
Inc. incurred a net loss during the year ended October 31, 2006, 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
and schedule do not include any  adjustments  that might result from the outcome
of this uncertainty. We hereby consent to the incorporation by reference of said
reports  in  the  Registration   Statements  of  CopyTele,  Inc.  on  Forms  S-8
(Registration  Nos.  33-72716,  33-62381,   333-16933,   333-53416,   333-69650,
333-99717, 333-105012, 333-120333 and 333-132544).
