Computer programming expert witness candidates typically have extensive experience in computer science, software engineering, and/or computer forensics. The chosen expert may be a member of an industry organization such as the Association of Software Professionals (ASP), the Developers Alliance, or the IEEE Computer Society Technical Council on Software Engineering (TCSE). In a high-profile case, or litigation involving a significant financial stake, a law firm may request a computer engineer or computer programmer with prior expert witness experience. A computer programming expert witness needs to not only have substantive expertise, but must also possess the ability to explain computer technology and electronic evidence to a judge and jury.
Often, matters requiring computer programming expert witness services involve intellectual property, such as patent infringement litigation, software copyright or trade secret disputes. A software forensic expert can analyze software code to determine if there is evidence to reveal intellectual property infringement or theft. A computer programming expert could also be called in to consult on technical issues or implementation issues, which could require digital forensics work. Litigation support by a computer programming expert witness could include computer software analysis, an expert report, expert opinion, and expert testimony in the courtroom. In addition, clients may seek a computer expert for pre-litigation consulting work.
