Recently, a committee of patent practitioners, academics, and judges, formed at the request of Chief Judge Michel of the Federal Circuit, has released a Patent Damages Handbook for federal district court judges to consult in patent cases. As stated on the committee's website:
The goal was to create a handbook drafted by a committee, national in scope, with members from the bench, bar and academia, including in-house counsel from a variety of industries, and patent damages experts. The underlying idea was to benefit from the collective experience of judges, attorneys, academics and economists in how best to achieve the "just, speedy and inexpensive determination" of patent damages. Recognizing that patent damages law is an area that continues to evolve, this handbook is not an attempt to restate substantive damages law or predict its future evolution but is instead focused on procedural practices that may be helpful in the adjudication of patent damages.
This handbook appears to be a good resource for both judges and patent practitioners.
Information about the handbook, as well as the handbook itself, can be found here.
