Information Systems Expert Witnesses
What is an information systems expert witness?
Information systems expert witness candidates typically have extensive experience in computer science, information technology, software design, telecommunications, and/or software engineering. An expert witness chosen may be a member of an industry organization such as the IEEE, the Association for Information Systems (AIS), or the Information Systems Security Association (ISSA).
What types of cases require an information systems expert witness?
An information technology expert witness could provide expertise in intellectual property matters such as a patent litigation or a trade secret dispute. It could be a patent infringement case in the District Court, an Inter Partes Review (IPR) in the PTAB, or a patent case or proceeding in the International Trade Commission (ITC). A digital forensics expert can determine if there is evidence to reveal intellectual property infringement or theft.
