Masur & Ouellette's Patent Law: Cases, Problems, and Materials is a patent law casebook offered for free download and at-cost (royalty-free) printing under the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International license. So far it has been adopted at over 60 law schools.

The casebook is focused on bringing conceptual clarity to the details of modern patent practice, while also placing patent law in its social context. Many practice problems throughout the casebook allow students to apply patent doctrines to fact patterns from real cases and to hypotheticals constructed to isolate and explain difficult concepts.

Faculty who adopt this textbook for their patent law courses may access accompanying resources, including a Teacher's Manual and PowerPoint slide deck, by emailing the authors at and
