The Patent Trial and Appeal Board's 2020 Apple Inc. v. Fintiv Inc. decision established six factors that guide its discretionary denial of an inter partes review or post-grant review petition in view of a parallel court case.
The Fintiv factors give significant weight to scheduling decisions of the trial court, including the proximity of the court's trial date, or Fintiv factor 2, and whether the court has granted a stay, or Fintiv factor 1. Some courts have shaped their dockets to maximize the chance of the PTAB denying review under Fintiv — e.g., by setting aggressive trial dates and refusing to grant stays pending PTAB proceedings.
Under those circumstances, unless a party files a petition in the PTAB immediately after it is sued in district court, it runs a high risk that its petition will be denied under Fintiv. Since Fintiv's 2020 issuance, the PTAB has incrementally refined its analysis of discretionary denials through precedential and informative decisions.
However, with the analysis comprising six nondispositive factors, there has been substantial uncertainty about how Fintiv would apply in any particular proceeding. Now, in a more sweeping change, U.S. Patent and Trademark Office Director Kathi Vidal recently issued interim procedures emphasizing some Fintiv factors over others.
As detailed below, the guidance gives petitioners — i.e., parties challenging patents — tools to help them overcome discretionary denials.
The guidance addresses:
- The merits of the petition, or Fintiv factor 6;
- Stipulations set out in the PTABs 2021 Sotera Wireless Inc. v. Masimo Corp. decision, or Fintiv factor 4;
- Trial dates, or Fintiv factor 2; and
- Fintiv's inapplicability to parallel proceedings in the U.S. International Trade Commission.
The merits: Compelling evidence of unpatentability is dispositive of the Fintiv analysis.
Under the guidance, the PTAB will not deny institution based on Fintiv if there is "compelling evidence of unpatentability." Where an IPR makes a "compelling, meritorious challenge" it will be allowed to proceed "even where district court litigation is proceeding in parallel."
The notion of a compelling challenge is relevant to Fintiv factor 6 — i.e., other circumstances that affect the board's exercise of discretion, including the merits.
The guidance recognizes that the burden of making a compelling unpatentability challenge is higher than the statutory threshold for institution of an IPR, i.e., a "reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition."[1]
The guidance also recognizes that a compelling unpatentability challenge is a higher burden than the elevated institution threshold for a PGR, i.e., "more likely than not that at least 1 of the claims challenged in the petition is unpatentable."[2]
The guidance states that a suitably compelling challenge is one "in which the evidence, if unrebutted in trial, would plainly lead to a conclusion that one or more claims are unpatentable by a preponderance of the evidence."
The words "plainly lead" suggest a high standard of proof, perhaps akin to the clear and convincing burden that is required to invalidate a patent in district court.
It remains to be seen how the PTAB will determine whether a petition is suitably compelling under the guidance. In the meantime, practitioners may emphasize certain facts in their cases that suggest a strong — or weak — showing.
For patent owners, it may be useful that in addition to the petition, any response affects whether there is a reasonable likelihood that the petitioner will prevail on at least one claim.[3]
So, if a patent owner preliminary response rebuts the substance of the petition, the patent owner might argue that the challenge is not compelling because it does not plainly lead to a conclusion of unpatentability.
Conversely, if the patent owner preliminary response does not rebut the substance of the petition, the petitioner might argue in reply that the evidence plainly leads to a conclusion of unpatentability, specifically because it stands unrebutted in the preinstitution phase.
For example, in the 2020 Facebook Inc. v. Onstream Media Corp. decision, the PTAB emphasized the lack of a substantive response:
Considering the Petition with its supporting evidence and the parties' arguments in deciding the merits of the Petition at this preliminary stage, including the fact that the Preliminary Response only addresses discretionary denial but not the merits, Petitioner presents a strong showing on the merits.[4]
As another example, in the 2020 SMIC Americas v. Innovative Foundry Technologies LLC decision,[5] the PTAB determined that:
[T]he merits of Petitioner's case are particularly strong. ... In particular, at this stage of the proceeding, Patent Owner only contests Petitioner's grounds for combining references, and its arguments are not supported by any testimony rebutting Petitioner's declaration testimony.
Of course, if the patent owner does not file a patent owner preliminary response at all, Fintiv may not be at issue since the board is less likely to sua sponte consider discretionary denial, absent unusual facts of which the board is aware.
To show compelling evidence, petitioners might emphasize why the merits of a petition plainly lead to a finding of unpatentability.
For example, some panels have considered the merits of a petition to be strong where the invalidity case is straightforward as to all asserted claims. In the December 2021 Micron Technology Inc. v. Godo Kaisha decision,[6] the PTAB found that:
[O]n the preliminary record, the merits of Petitioner's case are straightforward and strong, at least as to the ground involving Kishii and Ryan, and Patent Owner has not yet raised a persuasive defense to those allegations.
In June 2021, the PTAB made a similar finding that the substance of the petitioner's challenge was straightforward in Apple Inc. v. Koss Corp.,[7] although it ultimately did not institute in that case.
Naturally, whether the invalidity case is straightforward depends in part upon the complexity of the claims themselves.
In the PGR context, petitioners might show compelling evidence by emphasizing the strength of a Section 101 challenge, or some other statutory challenge that is more straightforward than a Section 102 or Section 103 analysis.
The PTAB has been willing to declare Section 101 challenges strong based on analogy to the USPTO's examination guidance on subject matter eligibility. In Supercell Oy v. Gree Inc.,[8] the PTAB in 2020 found that:
[a]n initial review of the merits of Petitioner's challenge under § 101 suggests that the merits are strong, which weighs in favor of instituting.
However, it then denied institution based on other factors.
Some PTAB decisions, including recent decisions issued before the guidance, have declined to evaluate the merits of a petition where the other Fintiv factors weigh strongly in favor of discretionary denial. In NXP USA Inc. v. Impinj Inc., the board on May 2 denied institution under Fintiv, noting that:
We need not decide whether the merits of Petitioner's asserted grounds are particularly strong because it would not impact our ultimate determination under §324(a). … Thus, we determine that the sixth Fintiv factor is neutral.[9]
The guidance contradicts decisions like NXP by giving overwhelming weight to the merits, i.e., a strong showing on the merits alone is sufficient to avoid discretionary denial, irrespective of the other factors.
If a party were able to file a timely rehearing petition pointing out conflicts between a panel decision and the guidance, the PTAB could consider reversing, since the guidance "applies to all proceedings pending before the Office."
In view of the limited 30-day window to request rehearing of a decision denying institution, it appears that few cases would be susceptible to rehearing under the guidance.[10]
Nevertheless, if a short extension of time could permit reconsideration under the guidance, parties might consider contacting the panel assigned to their case.
A Sotera stipulation is dispositive of the Fintiv analysis.
Fintiv factor 4 is "overlap between issues raised in the petition and in the parallel proceeding." When a party is sued on a patent in district court and subsequently files a petition for inter partes review of the same patent in the PTAB, there is usually substantial overlap because the petitioner also files a compulsory counterclaim for invalidity in district court.
Petitioners have experimented with various stipulations to diminish the effect of Fintiv factor 4. Sand-style stipulations are narrow, such as "if the IPR is instituted, Petitioner will not pursue the same grounds in the district court litigation," as the PTAB found in the informative 2020 Sand Revolution II LLC v. Continental Intermodal Group Trucking LLC decision.[11]
The PTAB found that a narrow Sand stipulation "weighs marginally in favor of not exercising discretion to deny institution."
Sotera-style stipulations are broad, such as "if IPR is instituted, [the petitioner] will not pursue in the District Court Litigation any ground raised or that could have been reasonably raised in an IPR," as defined in the precedential Sotera Wireless decision.[12]
The PTAB originally found that a broad Sotera stipulation "weighs strongly in favor of not exercising discretion to deny institution."
The guidance goes further than the PTAB's prior decisions and anoints the Sotera stipulation with dispositive weight. Going forward, "the PTAB will not discretionarily deny institution in view of parallel district court litigation" when the petitioner makes a Sotera stipulation.
The stipulation is effective if the IPR or PGR is instituted. A Sotera stipulation is therefore a Get Out of Fintiv Free card for petitioners facing a discretionary denial.
For example, if a petition is filed close to trial — i.e., close to the mean elapsed time for trial in the relevant district, under the guidance for Fintiv factor 2 — then a Sotera stipulation can effectively immunize the petition from discretionary denial.
Even before the guidance, statistically speaking, a Sotera stipulation was already a strong predictor that a petition would not be discretionarily denied. Now, though, petitioners will have certainty that a Sotera stipulation can prevent discretionary denial.
With the Sotera stipulation being dispositive of the Fintiv analysis, will some petitioners fall back to the weaker Sand-style stipulation, i.e., a stipulation not to raise grounds and references actually argued before the board in a parallel proceeding?
The answer may be yes for petitioners hoping to preserve some anticipation and obviousness defenses for trial based on printed publications.
A Sand stipulation has always had some effect in overcoming discretionary denial, even if less so than a Sotera stipulation. In view of the guidance, a Sand stipulation will probably continue to have some impact, but all the other Fintiv factors will still apply, including the time to trial, and whether the petition has compelling merits under the USPTO guidance. Indeed, at least one PTAB decision issued since the guidance found that a Sand stipulation caused Fintiv factor 4 to weigh against discretionary denial.[13]
The district court's scheduled trial date is no longer taken at face value.
Fintiv Factor 2 is the proximity of the district court's trial date to the PTAB's statutory deadline for a final written decision. This factor has been controversial when a district court sets an aggressive trial date falling earlier than the PTAB's deadline.
For example, parties have filed IPR petitions that were discretionarily denied based on the initially scheduled trial date in concurrent district court proceedings.
But in some of those district court cases, the trial date was later postponed due to litigation complexity, court congestion or COVID-19 shutdowns, such that the delayed trial date extended beyond the date an IPR decision would have been due.
This led to complaints from petitioners that the PTAB was giving too much credence to district courts' initial scheduling orders, without considering the delays and scheduling changes that typically occur in litigation.
To address these concerns, the guidance makes two significant changes to how the trial date is weighed under Fintiv: First, the PTAB will consider the court's median time to trial, instead of the scheduled trial date in a specific case.
Second, instead of considering a single judge's median time to trial, the PTAB will consider the districtwide median, which the guidance makes clear by including a link to recent statistics on the U.S. Courts website. These changes will likely diminish the effect of judges with "rocket docket" schedules in district court on the PTAB's Fintiv analysis.
Based on the U.S. Courts website's March 2022 statistics linked in the guidance, the fastest time to trial is in the U.S. District Court for the Eastern District of Virginia, at 18.1 months for the year ending March 31 — in prior years, that district had considerably shorter times to trial, averaging around 12 months for 2017-2020.
Other districts with heavy patent dockets moved more slowly: 24.2 months to trial for the U.S. District Court for the Eastern District of Texas, and 27.2 months for the U.S. District Court for the Western District of Texas.
But in earlier years, both of these districts clocked about 18 months to trial. Patent owners may use these statistics to argue that the most recent time-to-trial statistics skew high because of COVID-19, and that the speedier prepandemic statistics should control the analysis. But that rationale has already been rejected in at least one post-guidance institution decision.
The guidance hints that "the PTAB will also consider additional supporting factors such as the number of cases before the judge in the parallel litigation and the speed and availability of other case dispositions."
The guidance cites to the U.S. Court of Appeals for the Federal Circuit's decisions in In re: Genentech Inc.[14] and In re: Google LLC.[15]
Both of these decisions issued on writs of mandamus from district court orders denying motions to transfer: Google arose from the Western District of Texas, and Genentech arose from the Eastern District of Texas.
The guidance therefore links Fintiv's time-to-trial analysis to existing Federal Circuit doctrine comparing court congestion between two districts in a motion to transfer.
The Federal Circuit's decision in In re: Juniper Networks Inc.[16] labeled the court congestion factor as "the most speculative of the factors bearing of the transfer decision," and held that "it is improper to assess the court congestion factor based on the fact that the Western District of Texas has employed an aggressive scheduling order for setting a trial date."
Even though the PTAB's denial of institution is almost never appealable, the director is analogizing Federal Circuit case law to reduce the PTAB's emphasis on the "trial date" Fintiv factor.
Parallel ITC proceedings are not a basis for discretionary denial under Fintiv.
The guidance clarifies at page 7 that "the PTAB will not discretionarily deny petitions based on applying Fintiv to a parallel ITC proceeding."
It reasons at page 6 that the Fintiv factors seek to avoid duplicative efforts between the PTAB and courts, which does not include investigations at the ITC; the ITC lacks authority to invalidate a patent, and its invalidity rulings are not binding on the USPTO or a district court.
