PTAB Upholds Validity of Claim over Prior Art Despite A District Court Finding the Claim Invalid as Indefinite

Apr 14, 2016

Reading Time : 1 min

In reaching its final decision on validity, the PTAB first reconsidered two of its previous claim constructions. The PTAB had initially determined, pre-Williamson v. Citrix Online, LLC, 792 F.3d 1339 (Fed. Cir. 2015), that the claim limitations “proficiency sensing module” and “mode control module” were not means-plus-function limitations because of the strong presumption that claim limitations that do not use the phrase “means for” are not subject to 35 U.S.C § 112 ¶ 6. The Williamson decision, however, abrogated this presumption and, instead, directed courts to determine “whether the words of the claim are understood by persons of ordinary skill in the art to have sufficiently definite meaning as the name for structure.” If the words of the claim do not connote structure, then 35 U.S.C § 112 ¶ 6 applies. Following the Williamson decision and additional briefing from the parties, the PTAB found that neither of the disputed limitations, or the remainder of the claim, connoted structure for the modules to a person or ordinary skill, despite the claim reciting inputs and outputs to each module at a “very high level.” Thus, the PTAB reversed its previous decision, ruling that the limitations were means-plus-function limitations subject to 35 U.S.C § 112 ¶ 6.

The PTAB then found that the prior art did not anticipate the challenged claim, because petitioner had not identified any structure in the specification of the patent that corresponded to the two module limitations and, “as a result,” could not identify similar anticipatory structure in the asserted prior art references. The PTAB reached this finding despite knowing that a district court had found the claim indefinite, because the specification failed to disclose sufficient structural support for one of the module limitations, which suggests that petitioner had not pointed to any corresponding structure in the specification because such structure did not exist.

This case highlights the restrictions on the scope of inter partes review, which does not allow petitioners to argue for, or the PTAB to consider, invalidity based on indefiniteness.

The Federal Circuit vacated a district court’s fee award because the district court considered certain information that was not relevant to the question of whether plaintiff’s case was exceptional. Specifically, the Federal Circuit held that only those “red flags” that related to the successful Section 101 defense, which served as the basis for the district court’s grant of summary judgment, could be used to show the case was fatally flawed.

The Federal Circuit’s decision in Kyocera Senco Industrial Tools Inc. v. International Trade Commission articulated a bright-line test for patent expert admissibility: to testify from the perspective of a “person of ordinary skill in the art” (POSITA), the expert must at least meet the definition of a POSITA for the patents-in-suit. Absent that level of skill, Kyocera holds that the witness’s testimony is not sufficiently reliable or relevant enough to be relied on by a fact-finder.

The PTAB denied a petitioner’s motion to compel routine discovery that sought information from a parallel ITC investigation for alleged inconsistent positions taken by patent owner in the IPR. The board found that patent owner had not taken inconsistent positions but warned patent owner that it had an ongoing duty to produce any information inconsistent with arguments made during the present IPR, even if that information related to arguments patent owner had dropped at the ITC.

In Kyocera Senco Industrial Tools Inc. v. International Trade Commission, the Federal Circuit held that an expert must meet the definition of a “person of ordinary skill in the art” of the asserted patents in order to opine on infringement, among other issues. This new bright-line test and the underlying rationale, however, raised several new questions regarding expert admissibility. SeeFederal Circuit: Narrow Definition of Skill in the Art Dooms Expert’s Testimony” and “Grappling With A Bright-Line Patent Expert Admissibility Test.” The Federal Circuit recently addressed one of those questions, namely whether an expert must have acquired the requisite level of skill as of the time of the invention or whether it is sufficient for an expert to acquire that knowledge at a later date.

The Director of the USPTO initiated sua sponte review of a PTAB panel’s decision to impose sanctions based on patentee’s conduct during IPR proceedings. The PTAB cancelled all of patentee’s claims, including those not unpatentable on the merits, after finding that patentee deliberately withheld data relevant to the patentability of the claims at issue. In her review, the Director addressed which regulations are implicated upon a party’s misconduct during AIA proceedings and addressed whether entry of judgment in the trial was an appropriate sanction.
