Computer expert witness candidates typically have extensive experience in software development, information technology, computer engineering, and/or as a computer forensics expert. A computer expert witness needs to not only have substantive expertise, but must also possess the ability to explain electronic evidence and technology to a judge and jury. In a high-profile case, or litigation involving a significant financial stake, the legal team may request a specialist with prior expert witness testimony experience.

What types of legal cases call for a computer expert?

Court cases requiring computer expert witness services can involve intellectual property litigation, such as software copyright, patent infringement, or trade secret disputes. Law enforcement often use digital forensics experts for criminal investigations involving fraud or electronic discovery. Litigation support by a computer engineering expert could include forensic analysis, expert report preparation, depositions, and jury trial testimony. In addition, a law firm may request a computer expert for pre-litigation consulting work. Cahn Litigation Services is frequently called upon to locate experts that can support criminal or civil litigation requiring computer experts. Representative matters have encompassed:

The firm has the experience required to turn a search around quickly and provide qualified candidates that mirror the specifications set by the law firm. Sourcing technology experts for computer patent litigation is a particular area of expertise at Cahn Litigation Services.
