                  PHONE.COM FILES LAWSUIT AGAINST GEOWORKS

   Lawsuit Asserts Phone.com Products Do Not Infringe on Geoworks Patent
                  and Patent is Invalid and Unenforceable

   Redwood  city,  Calif.  (April  25, 2000)  Phone.com, Inc., a leading
   provider  of software enabling delivery of Internet-based applications
   and services to wireless telephones, announced today that it has filed
   a  lawsuit  in  the  United  States District Court in San Jose against
   Geoworks  Corporation.  The  lawsuit  alleges, and seeks a court order
   declaring,  that U.S. Patent No. 5,327,529 (the '529 patent), assigned
   to  Geoworks is not infringed by Phone.com and that the '529 patent is
   also  invalid  and unenforceable. As a leader in the wireless Internet
   industry,   Phone.com  took  this  action  in  response  to  Geoworks'
   aggressive attempt to require industry participants to obtain licenses
   under  the  Geoworks  patent. In its complaint, Phone.com asserts that
   Phone.com's technology does not infringe the Geoworks '529 patent, and
   that the patent is also invalid and unenforceable.

   Alan  Black,  Chief  Financial Officer and Vice President of Phone.com
   said,  "We  believe  that  this  lawsuit  will  produce an unequivocal
   declaration  that  Geoworks'  patent  has  no  relation to, and is not
   infringed  by,  Phone.com's  technology,  and  that,  in addition, the
   patent is invalid and unenforceable."
