Financial Systems Technology (FST) [NPE] filed suit against CDW and IBM, alleging that the defendants’ relational database technology infringes three patents related to a system that records and extracts data.  FST has filed three prior suits since 2004 against defendants including Oracle and Microsoft.  Its 2008 suit against Oracle was dismissed with prejudice in February 2011 subject to an undisclosed settlement agreement.  Karol Doktor is the named inventor on the patents-in-suit, which were assigned directly to FST in July 2003.  12/8, Northern District of Illinois, 1:2011cv08729.
