ITEM 8.01 OTHER EVENTS

     As previously reported in a Form 8-K filed by SPSS Inc. (the "Company") on
December 31, 2007, Norman H. Nie, a former director of the Company, has recently
informed the Company that, in his view, the Company's use of the SPSS trademark
is subject to a License Agreement (the "Agreement") dated September 30, 1976
between a predecessor of the Company, as licensee, and Norman H. Nie and C.
Hadlai Hull, as licensors.

     On January 3, 2008, the Company filed a complaint for declaratory judgment
in the U.S. District Court for the Northern District of Illinois against Dr. Nie
and Mr. Hull. The complaint seeks a declaratory judgment that Dr. Nie and Mr.
Hull are estopped from enforcing any rights under the Agreement and that the
Company shall be deemed to have an irrevocable, assignable and exclusive license
to use the SPSS trademark.

     Regardless of the outcome of this action, the Company believes it is in
full compliance with any obligations it may have under the Agreement and expects
to continue to have the right to use the SPSS trademark consistent with its past
practices. A copy of the complaint is attached to this report as Exhibit 99.1.
