Lessons for Today’s Fields of Intellectual Property and Trade from Epstein’s Insights about Private Law and History

Richard Epstein’s work on private law emphasizes themes that have survived since ancient Roman law.

They also can avoid many arcane doctrines in IP and trade law. Private law’s attention to business norms helped Grokster explore a modern online services’ liability for indirect IP infringement.

Private law also may help address business opportunism around trade in electronic transmissions and set top boxes
