In a decision today from the Federal Circuit, in Dell Inc. v. Acceleron, LLC, 2015-1513, -1514 (March 15, 2016), involving US Patent No. 6,948,021, the PTAB was reversed because its Final Written Decision relied upon a new argument that was first raised by Petitioner in oral argument.
In the underlying IPR, the PTAB determined that claims 14-17 and 34-36 of the ‘021 patent had not been shown to be unpatentable, but determined that claims 3 and 20 were unpatentable. In today’s Federal Circuit decision, the Court affirmed the Board’s determination that claims 14-17 and 34-36 were not shown to be unpatentable, but reversed and remanded relative to the unpatentability determinations of claims 3 and 20.
With regard to claim 20, the Court took the Board to task for failing to give meaning to all of a claim’s terms. The claim term at issue requires a microcontroller with a connection to remotely poll a CPU module. Decision at 11. The Board’s construction, in effect, ignored the “remotely poll” limitation from the claim, meaning that the Board’s claim construction was unreasonable. Id. at 13.
The more groundbreaking aspect of the Court’s decision, however, relates to the Court’s remand of claim 3. The Court held that, because the argument upon which the Board relied was first identified by Petitioner in the oral argument, Patent Owner was denied a fair opportunity to respond to the basis of cancellation. Id. at 13. As such, the Board’s decision was vacated and remanded. This holding is interesting because previous PTAB Final Written Decisions relied upon new evidence and argument advanced for the first time in reply or on appeal, but the Court did not take issue with those PTAB decisions.
More specifically, Patent Owner argued in its Patent Owner response that the “caddies” required by claim 3 were not shown by the “articulating door” from the prior art, that was identified in the Petition. In its reply brief, Petitioner presented the new argument that the caddies were also shown in the prior art’s power-supply mounting mechanisms. At the oral hearing, Petitioner expanded on this argument, arguing that unlabeled “slides” from the prior art mounting mechanisms constituted the claimed caddies. In the Final Written Decision, the Board relied upon this new argument from the oral argument, determining that claim 3 was unpatentable based on the disclosure from the prior art of the slides.
The Court noted the statutory and regulatory bases for the requirement that the Board put a Patent Owner on notice of the bases upon which it determines a claim to be unpatentable. Id. at 13-14. In view of those requirements, “the Board denied [Patent Owner] its procedural rights by relying in its decision on a factual assertion introduced into the proceeding only at oral argument, after [Patent Owner] could meaningfully respond.” Id. at 14.
Because the oral argument does not provide Patent Owner with any opportunity to supply evidence, Patent Owner had no opportunity to comprehensively address this contention. In its Final Written Decision, the Board had dismissed Patent Owner’s argument that this “slide” argument was new, by concluding that Petitioner pointed to the “slides” in its reply. The Federal Circuit disagreed, finding that the key factual assertion was only specifically made at the oral hearing. Thus, in its holding, the Court pointed to the fact that Petitioner has not shown “that there can be no genuine factual dispute” on the issue of anticipation and, as such, vacated the Board’s cancellation of claim 3 remanded the case for further proceedings. Id.
The Federal Circuit’s decision is a glimmer of hope for Patent Owners. The relatively unfettered discretion the Court has otherwise been affording the Board has (at least temporarily) been limited.
