Hardback
This thoroughly updated Fourth Edition includes all significant legislative and judicial developments up to January 2012, including the America Invents Act. In addition, existing materials have been streamlined and restructured, allowing more recent topics and developments to be covered in some depth without significantly lengthening the book. This edition has both depth and breadth of coverage of central issues, with optional extensions into additional topics, thus giving professors tremendous flexibility in choosing the areas they wish to emphasize.
