Software Expert Witnesses

What is a software expert witness?

Software expert witness candidates typically have extensive experience in computer science, software development, computer forensics, electrical engineering, telecommunications, and/or information technology. A software engineer has expertise in programming languages, software development, and computer operating systems, and applies engineering principles to create software systems. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a testifying expert with prior experience. In addition to technical expertise, a software expert witness must possess the ability to explain complex software issues to a judge and jury.

What types of cases require a software expert witness?

Often, matters requiring software expert witness services involve intellectual property, such as patent infringement litigation, software copyright, or trade secret disputes. A software forensic expert can analyze complex software source code to determine if there is evidence to reveal intellectual property infringement or theft. A software expert could also be called in on breach of contract disputes or to consult on software product technical issues.

Software expert witness case examples

Representative matters where Cahn Litigation Services has searched for experts include:

• a consumer electronics class action involving firmware updates,
• copyright infringement suit filed in Maryland,
• cybersecurity cases,
• Los Angeles e-commerce dispute,
• software patent IPRs, and
• a technology expert to investigate select Android devices.

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

Litigation support by a software expert witness could include computer software analyses, research and authoring expert reports, providing expert opinions, and expert witness testimony at deposition and in the courtroom. In addition, law firm clients may seek a computer scientist or software industry expert for pre-litigation consulting work.

Cahn Litigation Services has the experience required to turn a search for a software expert witness around quickly, providing the right balance of expertise and testimony experience.
