Clarification of the Effective Date Provision in the Final Rule for Ex Parte Appeals

On June 10, 2008, the United States Patent and Trademark Office (Office) published the final rule that amends the rules governing practice before the Board of Patent Appeals and Interferences (BPAI) in ex parte patent appeals. The effective date provision in the final rule states that the effective date is December 10, 2008, and the final rule shall apply to all appeals in which an appeal brief is filed on or after the effective date. The final rule requires, in part, appeal briefs in a new format relative to the format required prior to the rule revision. The Office is issuing this notice to clarify that it will not hold an appeal brief as non-compliant solely for following the new format even though it is filed before the effective date.
