What is a computer expert witness?

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 cases require a computer expert witness?

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.

Computer expert witness case examples

Representative matters have encompassed:

• computer security,
• operating systems,
• Oregon retail store data breach,
• cell phone data recovery,
• automation software licensing,
• multimedia software source code copyright,
• computer forensics expert witness for a software design trade secrets case,
• ecommerce computer systems expert analysis,
• artificial intelligence,
• mobile device software application,
• cybersecurity, and
• information security.

What litigation support work might a computer expert witness be expected to perform?

Litigation support by a computer engineering expert could include forensic analyses, authoring expert reports, depositions, and jury trial testimony. In addition, a law firm may request a computer expert for pre-litigation consulting work.

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.
