The monthly numbers of Patent Trial and Appeal Board (PTAB) petitions filed for the past four months have been within a 14-petition range, after displaying volatility at the start of the year.
In October, 155 total PTAB petitions were filed. This compares with 154 in September, 143 in August and 157 in July. Two other months this year fell within that range. June was the high for the year, with 176. January was the low, with 99.
Inter partes review (IPR) petition filing was steady in October. The 149 petitions was barely up from 148 in September. (You can read our analysis of third-quarter PTAB filing here.)
The five covered business method petitions in October was the most since June. Only one post-grant review petition (PGR) was filed.


According to data pulled from the Docket Navigator database, Apple was the biggest filer in October, with 15 petitions. All but one of them challenged patents owned by Papst Licensing, which was the most targeted patent owner in October.
Samsung was next in the petitioner rankings, with 13. Social media company Facebook was the third-busiest filer, with 12 petitions, eight of which involved its Instagram subsidiary.
Facebook has filed 39 PTAB petitions since July 2013, 24 of which have come this year. Its October filing consisted of four CBMs and eight IPRs. Eight of the petitions challenged seven patents owned by Skky for media delivery platforms. Four challenged one patent owned by Bruce Zak related to a system and method for managing content on a network interface. Skky sued Facebook for patent infringement in the District of Minnesota in January this year. Zak sued Facebook for patent infringement in the Eastern District of Michigan in September last year.

Another CAFC unreviewability ruling
The most important Federal Circuit action on a PTAB appeal in October was the rehearing in Medtronic v Robert Bosch. The original decision was reconsidered because of the Supreme Court’s Cuozzo decision. The Federal Circuit panel reaffirmed its order that a determination by the PTAB to discontinue IPR proceedings was not reviewable on appeal. The Board had terminated the IPR because it said Medtronic failed to identify all real parties in interest.
“The Board’s vacatur of its institution decisions and termination of the proceedings constitute decisions whether to institute inter partes review and are therefore ‘final and nonappealable’ under § 314(d). Nothing in Cuozzo is to the contrary,” said the Federal Circuit.
It added: “We conclude that under Cuozzo a decision whether to institute inter partes review proceedings pursuant to § 314(a) (the issue in Cuozzo) and a reconsideration of that decision (the situation here) are both barred from review by § 314(d).”
Knobbe Martens provided a summary of Federal Circuit cases that have ruled on reviewability of IPR institution. The appeals court has found nearly all decisions related to the institution of IPR proceedings to be unreviewable.

Lawyers at Knobbe Marten commented: “Medtronic provides yet another example that statutory requirements such as a real party in interest are considered to be ‘closely related’ to the decision to institute IPR proceeding and are therefore not reviewable on appeal. While the door to requesting judicial review of an IPR institution decision appears to be closed in most cases, the two-part test provided in Husky suggests that it may not be completely closed.”
Jones Day commented: “It is clear that the Supreme Court and the Federal Circuit believe Congress ceded institution decisions and many related procedural issues to the realm of unreviewable decisions. It will be interesting to observe what other issues the Federal Circuit will find to be ‘closely related’ to the PTAB’s decision to institute IPRs.” The law firm said one example is that it is unclear whether an appeal can be maintained from a petition that is denied institution under § 315(e)(1) due to estoppel from a prior final written decision.
Another Federal Circuit ruling of interest was a Rule 36 decision affirming the invalidation of the CBM patents that were specifically cited during the debate in Congress about the America Invents Act, in DataTreasury v Fidelity (you can read an analysis of that decision here).
PTAB decisions of interest
The first final written decisions on Coalition for Affordable Drugs petitions have come out in the past month. So far, seven IPRs have made it to final written decision. Six of these have resulted in invalidated claims of a total three patents, with two of those patents having all challenged claims invalidated. You can read a full analysis here.
In Duodecad IT Services Luxembourg v WAG Acquisition, the PTAB in a final written decision determined that a patent’s file history qualifies as a “printed publication” under 35 USC 102(b). Jones Day noted: “For petitioners this decision counsels towards examining a prior art patent’s file history to determine if it contains additional information that is not present in the patent itself, as the combination of the patent and its file history contents could serve as a persuasive ground of unpatentability.”
In GoPro v Contour IP Holding, the PTAB found that a catalogue that was distributed at a trade show attended by thousands was not a printed publication. The Board reasoned that there was no evidence that persons of ordinary skill in the art were at the show because the audience was dealers and vendors members and not the general public.
One interesting case to keep an eye on involves sovereign immunity of state universities. The PTAB will rule on whether state sovereign immunity prevents an IPR challenge from being maintained against a University of Florida patent.
As Foley & Lardner’s Steve Maebius noted on the PTAB Trial Insights blog: “State university patent owners who have availed themselves of the remedies offered by infringement litigation in federal courts, have still been able to use the sovereign immunity shield of the 11th Amendment to prevent other suits against them challenging validity of their patents … While the use of state sovereign immunity as a shield in patent litigation is not new, this appears to be the first instance of it being asserted as a defence in an IPR or AIA proceeding.”
USPTO proposes fee increases and privilege change
At the end of September the USPTO released proposed patent fee adjustments. These included PTAB trial fee increases “aimed at better aligning these fees with the USPTO’s costs and aiding the PTAB to continue to meet required AIA deadlines”. PTAB fee increases of between 18% and 56% have been proposed.
These include: IPR request fee for up to 20 claims increasing to $14,000 from $9,000; IPR post-institution fee for up to 15 claims increasing to $16,500 from $14,000; PGR or CBM review request fee for up to 20 claims increasing to $16,000 from $12,000; and PGR or CBM review post-institution fee for up to 15 claims increasing to $22,000 from $18,000.

The USPTO is holding a comment period on the fee increases that closes on December 2.
Marshall Gerstein’s PTABWatch blog explained: “The Patent Office now has three years of data and, therefore, an insight into the costs of administering AIA trials and estimating the demand for these proceedings. And the notice explains that the fee adjustments the Patent Office proposes are meant to align more appropriately with this insight and estimate.”
In October, the USPTO proposed new rulemaking that would recognise patent agent privilege in PTAB proceedings. This would expand privilege to cover communications with foreign agents, which is not addressed under the rules now. It would apply for IPR, PGR, CBM and derivation proceedings.
The Office is proposing to amend the PTAB rules to “recognise that, in connection with discovery conducted in certain proceedings at the [USPTO], communications between US patent agents or foreign patent practitioners and their clients are privileged to the same extent as communications between clients and US attorneys.” A comment period on the proposal closes on December 19.
Scott McKeown on the Patents Post-Grant blog commented: “The rule is designed to ensure consistency in such determinations before the agency as the common law on privilege for domestic and foreign patent practitioners varies across jurisdictions. Different approaches are taken, and results sometimes conflict. This may lead to administrative inefficiencies and inconsistencies in outcomes, as PTAB must select which set of common law rules to follow.”
Supreme Court denials
The Supreme Court denied cert in six PTAB cases in October.
According to the PTAB Bar Association, the Court denied petitions challenging IPRs’ constitutionality (MCM Portfolio, Cooper v Lee), statutory interpretation of AIA provisions (Trading Technologies, GEA Process), other AIA issues (Merck & Cie, MacDermid) and reexaminations (Pactiv and MacDermid).
