What is an acceptable source for case law citations in an Appeal Brief at the USPTO?

The correct response highlights the importance of referring to authoritative sources for case law citations in an Appeal Brief submitted to the USPTO. The United States Reports, which contain opinions from the U.S. Supreme Court, and the West Reporter system, which aggregates federal and state court decisions, are recognized and widely accepted sources of case law. Citing from these official reporters ensures that the legal arguments presented in the Appeal Brief are supported by established jurisprudence that is well-respected and authoritative in the legal community.

Utilizing these sources also reflects the adherence to standard legal practices, as both the United States Reports and the West Reporter system provide precedential and well-researched cases that support the positions taken in an appeal. In contrast, other options such as citing from only state court reporters or relying on unpublished case law may not hold the same weight or relevance at the federal level, which may lead to challenges in the credibility of the arguments presented.
