An information retrieval expert witness typically has an advanced degree and expertise in electrical engineering, computer science, and/or software engineering – depending on the specific technology and product involved the case. On behalf of the plaintiff or defendant, Cahn Litigation Services is called on by law firm clients to locate expert witnesses that can support matters involving data storage and retrieval technology. Most often the expert witness chosen is member of an industry organization such as the Association for Computing Machinery’s Special Interest Group on Information Retrieval (SIGIR), and/or IEEE. An information retrieval expert witness should have a deep understanding not only of the technology, but also of the data storage and retrieval market and competitive landscape.
An information retrieval expert witness could provide expertise in intellectual property matters, such as a patent litigation in federal court 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. A subject matter expert with specialized knowledge in electronically stored information could also be utilized in a criminal case. In a litigation support scenario, a technical expert can expect courtroom testimony, as well as other expert witness services such as depositions, expert opinion, expert testimony, expert report, forensic analysis, and related consulting activities.
In high profile cases, or litigation involving a significant financial stake, previous expert witness experience is often a requirement by the attorney team. An information retrieval expert witness needs to not only have technical expertise, an expert witness should possess the ability to explain technology and electronic evidence to lay people, including a jury. In addition, clients may seek an industry expert for pre-litigation consulting work.
