                                                                    ------------
                                 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.
