This seminar explores the use of scientific evidence in cases where the science is complicated but not itself in dispute. The major emphasis is on patent infringement litigation. The parties' experts have two different tasks: the obvious one is to explain the science to the judge and jury, the less obvious one is to help the litigators determine which legal issues to argue at all. Thus, both the lawyer and the scientist must educate the other about their specialties. Eight law students and eight science or engineering graduate students work in four teams of four: an expert and a litigator for plaintiff, an expert and a litigator for defendant. The teams prepare simulations involving expert testimony, both direct and rebuttal, and related documents.
