Expertise, Experience, and Ideology on Specialized Courts: The Case of the Court of Appeals for the Federal Circuit

What roles do prior expertise and accumulated experience play in shaping ideologically consistent voting on a specialized court? Using a dataset of obviousness patent cases from the Court of Appeals for the Federal Circuit spanning 1997-2007, we show that prior expertise enhances the influence of ideology on judicial decisionmaking, but that accumulated experience does not. In addition, we build on previous work and show that ideology is a factor in decisionmaking in technical areas of law, contrary to the received wisdom on patent cases.
