            CONSENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


We have issued our report dated January 4, 2005,  except for Note 10 as to which
the date is January 12, 2005, accompanying the financial statements and schedule
included in the Annual Report of CopyTele,  Inc. on Form 10-K for the year ended
October 31, 2004. 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,  2004,  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 hereby
consent to the  incorporation  by reference  of said report in the  Registration
