Federal Circuit Reluctantly Applies Mayo and Denies Petition for Rehearing en banc in Medical Diagnostic Case

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.

The Central District of California ruled that the heightened pleading standard of Federal Rule of Civil Procedure 9(b) applies to all three prongs of a false patent marking claim, including the third prong, competitive injury. In doing so, took a clear stand on an issue with a nationwide split among district courts.

In a patent case containing a variety of federal and state law claims, the District of Massachusetts retained supplemental jurisdiction over the state law claims even after all the federal law claims were dismissed.

The Federal Circuit recently upheld the USPTO’s authority under the estoppel provision 37 C.F.R. § 42.73(d)(3)(i) to prohibit a patent owner from obtaining patent claims that are not patentably distinct from claims previously declared unpatentable in inter partes review (IPR) proceedings. However, the court clarified that the regulation applies only to new claims or amended claims, not previously issued claims.

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. See “Federal 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.
