Engineering expert witness candidates are typically licensed professional engineers with areas of expertise covering mechanical engineeringcivil engineeringmetallurgical engineeringelectrical engineeringstructural engineeringgeotechnical engineeringbiomechanicsautomotive engineering, and/or forensic engineering. An engineering expert could provide expertise in intellectual property matters, including patent infringement or a trade secret dispute. It could be an Inter Partes Review (IPR) in the PTAB (where the only expert testimony is through a deposition), or a patent case or proceeding in the International Trade Commission (ITC). An engineer might provide expert opinion in a matter such as a product liability case, accident investigation, or provide testimony in a personal injury case. Litigation support could include expert witness services such as expert report preparation, failure analysis, design defect analysis, accident reconstruction, forensic engineering, and expert witness testimony in the courtroom. In addition, law firm may request an expert for pre-litigation consulting services.
