Shaughnessy Borowski
& Gagner – (Philip Ganger)
CTI Inc. v. Software Cartesians
Served as an expert witness for
Software Cartesians. The latter consisted of programmers that left CTI to
establish their own company producing a similar application program. The
defense argued: although the programs were similar, no IP of CTI was used in
the development of Software Cartesians application.
The applications were written in C
and C++ and were over 10,000 lines of code.
Judge deemed our technical arguments
more convincing than those of the opposing expert.
Pettit and Martin (extinct law firm)
Hewlett Packard v. GTE government systems
Served as an expert witness for GTE
in a case of a government contract award.
Our analysis of the Army’s RFP
showed a clear ambiguity of a critical requirement. We tested the requirement,
sanitized to hide all details, on a large group of students. The group revealed
two contradictory interpretations. We recommended restatement of the RFP.
Army decided to reconsider (unaware
of our concurrence).
Cohen
and White – (David Cohen)
Sun Microsystems v. Harris
Supported an expert witness for
Harris in a case of evaluation performance of a large system.
Our task was restricted to the
simulation of millions of customers of a network of computers dispersed all
over the world.
Harris lost on judge's decision of
no ground for the claim.
Steptoe and Johnson – (William J. Koegel) 1995
CACI v. Pentagen
Served as an expert witness for
CACI. Pentagen claimed that their process was stolen by CACI. We showed that
Pentagen claim is baseless.
The case involved a rarely used
programming language and the technical foundations were also quite esoteric.
Won in summary judgment.
Piper
and Marbury – (Richard P.
Rector)
Sun Microsystems v. Digital
Served as an expert witness for DEC
(Digital Equipment Corporation) in a case of a government contract award.
Scope of work was limited to
marginal issues of the case. Another expert who also wrote the final report
handled the central issues. We did not concur with the final report.
Lost on judge's decision to support
Sun Microsystems.
Shaughnessy Borowski & Gagner - (Philip Ganger)
Bulk Mailing v. Frederic Mailing
Served as an expert witness for
Frederic Mailing.
Showed that Bulk Mailing had a large
investment in substantial application while Frederic Mailing had a small 3rd Generation application.
Bulk Mailing realized
that there is no ground for the lawsuit.
Sides settled with Bulk Mailing paying full expenses.
Ober Kaler – (John E. Steren) 1998-1999
Litton v. Tiburon
Served as an
expert witness for
Tiburon.
Litton claimed Tiburon's product is
derived from PRC (Litton subsidiary) public safety and justice applications
IP.
Case lasted more than 8 months and involved over four million lines of code in dozens of application all in the public safety and justice application area. Litton employed five software experts while Tiburon has one (us) only. In a complicated report we showed that some of the IP features were already in the public domain before both companies entered that business and the other claims were baseless.
Settled the night before trial with
minor financial damage to Tiburon. Since Litton is an industry giant and
Tiburon a small company, it was a great win for Tiburon and a great win over Howrey Simon Arnold & White (opposing
counsel).
LeBoeuf, Lamb, Greene &
MacRae (A British Law Firm) 1999
A British registering company v.
Pentagen technologies International
Served as an expert witness for the
registering company.
The case was similar to the CACI v.
Pentagen above. Done additional analysis and reporting as follow up to CACI v. Pentagen.
The technology has changed since the 1995 case and the Pentagen had to be
adopted to run and be evaluated.
Judge dismissed case due to British
procedural issues.

Commonwealth of Virginia v. Jon
Honhart
Served as an expert witness for the
defense of Jon Honhart who was indicted for breaking into the network of The Signature Group.
Expert report and testimony claimed
that the security and event logs of the system are invalid and, therefore, the
police has no evidence.
Jon Honhart was acquitted.

Served as an expert witness for Ansaldo.

Falke
& Dunphy (Ohio) (Kenneth Lazarus - Washington, DC) 2002
We performed initial analysis to
assess Americom’s application was part of Dayton Data Processing’s application.
Although this legacy application was
written in an obsolete programming language and the potential defendant’s
application was 10 times larger by this time, our preliminary work showed
strong and convincing evidence of stolen actual code based on the
identification of unique patterns in both applications.
Wiley
Rein & Fielding – (Kevin P. Anderson)
2003
DataDirect technologies v. I-Net
Software GMBH (Germany)
Served as an expert witness for DataDirect technologies.
Initial analysis indicated high likelihood that I-Net software is a copy.
