Revision of Patent Term Adjustment Provisions Relating to Appellate Review

The United States Patent and Trademark Office (Office) is proposing to revise the patent term adjustment provisions of the rules of practice in patent cases. The patent term adjustment provisions of the American Inventors Protection Act of 1999 (AIPA) provide for patent term adjustment if, inter alia, the issuance of the patent was delayed due to appellate review by the Board of Patent Appeals and Interferences (BPAI) or by a Federal court and the patent was issued under a decision in the review reversing an adverse determination of patentability. The Office is proposing to change the rules of practice to indicate that the period of appellate review under the patent term adjustment provisions of the AIPA begins when jurisdiction over the application passes to the BPAI rather than the date on which a notice of appeal to the BPAI is filed. The Office recently published the final rule (eff. date Jan 23, 2012) concerning practice before the BPAI in ex parte appeals and defined that jurisdiction of the appeal passes to the BPAI at the earlier of the filing of the reply brief or upon the expiration of the time in which to file a reply brief. See Rules Of Practice Before the Board of Patent Appeals and Interferences in Ex Parte Appeals 76 FR 72270, 72273 (November 22, 2011). Accordingly, for purposes of calculating patent term adjustment based upon appellate review, the impact of the rule change would be to reduce the amount of patent term adjustment awarded for successful appeal under 35 USC 154(b)(1)(C)(iii). However, the impact may be offset by potentially increasing the amount of patent term adjustment awarded for failing to issue the patent within three years of the actual filing date in the United States under 35 USC 154(b)(1)(B). The patent term adjustment award for the three year provision may increase when the examiner reopens prosecution after a notice of appeal is filed (e.g., following a pre-appeal conference or an appeal conference) and the patent issues thereafter, because the period of time between the filing of the notice of appeal and the examiner's reopening of prosecution would no longer be deducted under 35 USC 154(b)(1)(B)(ii).
