Patent cases are becoming more and more complex every day. Biotechnology, nanotechnology and semiconductor manufacturing are just a few of the technical fields that Judges may face when presiding over patent cases. Discovery in patent cases also often involves complex and difficult issues of relevancy and further involves disputes that are time consuming to resolve.
