                                                                    ------------
                                  CERTIFICATION
                                  -------------
I, John B. Nano, Chairman, President, Chief Executive Officer and Interim Chief
Financial Officer certify that:

1.     I have reviewed this Annual Report on Form 10-K of Competitive
Technologies, Inc. (the "Company");

2.     Based on my knowledge, this report does not contain any untrue statement
of a material fact or omit to state a material fact necessary to make the
statements made, in light of the circumstances under which such statements were
made, not misleading with respect to the period covered by this report;

3.     Based on my knowledge, the financial statements, and other financial
information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the Company as of,
and for, the periods presented in this report;

4.     I am responsible for establishing and maintaining disclosure controls and
procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
Company and we have:

     (a)  designed  such  disclosure  controls  and  procedures,  or caused such
          disclosure  controls  and  procedures  to  be  designed  under  our
          supervision,  to  ensure  that  material  information  relating to the
          Company,  including its consolidated subsidiaries, is made known to us
          by  others  within  those  entities, particularly during the period in
          which  this  report  is  being  prepared;

     (b)  evaluated  the  effectiveness  of  the  Company's  disclosure controls
          and  procedures and presented in this report our conclusions about the
          effectiveness of the disclosure controls and procedures, as of the end
          of  the  period  covered  by this report based on such evaluation; and

     (c)  disclosed  in  this  report  any  change  in  the  Company's  internal
          control  over  financial  reporting that occurred during the Company's
          most recent fiscal quarter (the Company's fourth fiscal quarter in the
          case  of  an  annual  report)  that  has  materially  affected,  or is
          reasonably likely to materially affect, the Company's internal control
          over  financial  reporting.

5.     I have disclosed, based on my most recent evaluation of internal control
over financial reporting, to the Company's auditors and the audit committee of
the Company's Board of Directors (or persons performing the equivalent
functions):

     (a)  all significant  deficiencies  and  material  weaknesses  in  the
          design or operation of internal control over financial reporting which
          are  reasonably  likely  to  adversely affect the Company's ability to
          record,  process,  summarize  and  report  financial  information; and

     (b)  any fraud,  whether  or  not  material,  that  involves  management or
          other  employees who have a significant role in the Company's internal
          control  over  financial  reporting.
