Expert Witness Testimony

There is more to being a great expert witness than just being a great engineer.  Of course, to testify successfully at deposition or in front of a judge or jury, an expert must understand the technology at issue.  However, the expert must also be well prepared, have the appropriate credentials and experience, and be able to clearly communicate his knowledge to the judge or jury.  Barr Group's testifying experts have a remarkable ability to clearly and credibly communicate complex technical topics.

The first step in all of this is to review the software source code, electronics, and related documents and/or to perform reverse engineering and testing.  The expert then prepares an expert report, declaration, or witness statement that records the steps performed and learnings as well as each of the expert's opinions.  Our experts have written and submitted many expert reports for all types of technology litigation and are well versed in the formats required in the various venues, such as by Rule 26 of the Federal Rules of Civil Procedure or in an Inter Partes Review (IPR).

When it comes time to be deposed or testify, Barr Group's experienced software expert witnesses work closely with retaining counsel to fully prepare to clearly present the technical information and opinions from their expert report during a direct examination and to defend their opinions as they are challenged in a cross-examination.
