Dear Mr. Kronforst:

We have received your letter dated February 20, 2008, and provide the following
response thereto:

Form 10-K for Fiscal Year Ended October 31, 2007

Item 8. Financial Statements and Supplementary Data

Note 4. Investment in and Related Party Transactions with Digital Info Security
Co., Inc., page F-15

Comment:  We note your disclosure that your investment in DISC is recorded at
          cost.  Please tell us how you considered paragraph 3(a) of SFAS 115
          with respect to this investment.

Response: Digital Info Security Co. Inc. ("DISC-CO") was incorporated in
          Colorado in October 2004 and commenced operations in April 2005. In
          2006, CopyTele acquired an aggregate of 12,200,000 shares of DISC-CO's
          common stock in private transactions. DISC-CO's common stock was not
          registered under the Securities Exchange Act of 1934 ("Exchange Act").
          In March 2007, DISC-CO merged with an inactive Delaware company
          formerly known as Teardrop Golf Company ("DISC-DE"). CopyTele's
          understanding is that DISC-DE survived the merger. Teardrop Golf
          Company's common stock was quoted on the Pink Sheets, but it had
          filed a Form 15 in January 2007 to terminate the registration of its
          securities under the Exchange Act. After the merger, DISC-DE stock has
          continued to be traded on the Pink Sheets. According to DISC-DE's most
          recent public financial report, as of September 30, 2007 we held
          approximately 12% of the outstanding common stock of DISC-DE.


          The DISC-DE stock held by CopyTele is restricted stock and
          cannot be sold or otherwise disposed of in the absence of
          either a registration statement under the Securities Act of
          1933 ("Securities Act") or an exemption from the registration
          provisions of the Securities Act. Because CopyTele acquired its
          shares of DISC-DE stock in the merger between DISC-CO and
          DISC-DE, Rule 144 is not available for the sale of CopyTele's
          DISC-DE stock until the one-year anniversary of the merger, on
          March 28, 2008. Because CopyTele may be an affiliate of
          DISC-DE due to its ownership of approximately 12% of the
          outstanding common stock of DISC-DE, in order for CopyTele to
          sell or dispose of the DISC-DE stock under Rule 144 on or
          after the one-year anniversary of the merger, all of the
          requirements of Rule 144 must be satisfied, including the
          current public information requirements set forth in Rule
          144(c). DISC-DE is not currently subject to the reporting
          requirements of the Exchange Act, and, accordingly, it must
          satisfy the current public information requirements set forth
          in Rule 144(c)(2), which states that the issuer must make the
          information required by Rule 15c2-11 under the Exchange Act
          publicly available. Currently, certain of the information set
          forth in Rule 15c2-11 does not appear to be publicly
          available, such as the nature and extent of its facilities,
          the names of the members of its board of directors, and
          information about whether any broker-dealers are affiliates of
          it. CopyTele is unable to predict whether DISC-DE will be in
          compliance with the public information requirements of Rule
          144(c)(2) in the future.

          SFAS 115 states that restricted stock does not meet the
          definition of paragraph 3(a), except that any portion of a
          security that "can be reasonably expected to qualify for sale
          within one year, such as may be the case under Rule 144 or
          similar rules of the SEC, is not considered restricted."
          Because we do not believe that the restricted DISC-DE common
          stock held by CopyTele can be reasonably expected to qualify
          for sale within one year for the reasons stated above, we do
          not believe that the fair value of the investment in DISC-DE
          is readily determinable.

CopyTele acknowledges that:

     o    CopyTele is responsible for the adequacy and accuracy of the
          disclosure in its filings;

     o    Staff comments or changes to disclosure in response to staff comments
          do not foreclose the Commission from taking any action with respect to
          the filing; and

     o    CopyTele may not assert staff comments as a defense in any proceeding
          initiated by the Commission or any person under the federal securities
          laws of the United States.


Thank you very much for your comment. If you have any further questions or
comments, please feel free to contact me at (631) 549-5900.

Very truly yours,
COPYTELE, INC.
