Sleep Better: Amendments Proposed during IPR Deemed Proper and Valid

by | Nov 29, 2022 |

The US Court of Appeals for the Federal Circuit affirmed the Patent Trial & Appeal Board’s (Board) finding that proposed amendments made during an inter partes review (IPR) are valid and proper despite the inclusion of changes not related to patentability issues raised in the petition. Nat’l Mfg., Inc. v. Sleep No. Corp., Case No. 21-1321 (Fed. Cir. Nov. 14, 2022) (Stoll, Schall, Cunningham, JJ.)

We’ve likely all seen the commercials promising a proven quality of sleep. Sleep Number is the owner of numerous patents, including several directed to methods for adjusting “the pressure in an air mattress ‘in less time and with greater accuracy’ than previously known.” The patents state this is achieved by taking pressure measurements at the valve enclosure and applying a pressure adjustment factor that is iteratively revised using an “adjustment factor error.” The patent states that this method allows for monitoring the pressure of the air mattress without the need to turn off the pumps.

American National Manufacturing challenged the validity of the patents in an IPR proceeding, claiming that most were rendered obvious by the prior art of Gifft in view of Mittal and Pillsbury and that six of the dependent claims requiring a “multiplicative pressure adjustment factor” would have been obvious in further view of Ebel. Gifft disclosed an air-bed system using valve assembly pressure to approximate the air chamber pressure and Mittal and Pillsbury both disclosed using additive offsets to improve accuracy. Ebel disclosed using both additive and multiplicative components to accurately measure the actual pressure in an inflating or deflating air bag.

The Board agreed with American National that it would have been obvious to combine Gifft, Mittal and Pillsbury and that the resulting combination rendered most of the claims obvious, but it also noted that the combination failed to show that a “skilled artisan would have applied Ebel’s multiplicative factors” to the prior art. However, in each proceeding Sleep Number filed a motion to amend the claims contingent on a finding that the challenged claims were unpatentable. The proposed claims included the “multiplicative pressure adjustment factor” that the Board had determined was not unpatentable along with other non-substantive changes.

American National took issue with these amendments, arguing they were legally inappropriate, non-enabled because of an error in the specification and lacked written description support. The Board disagreed. American National appealed. Sleep Number cross-appealed the Board’s finding of obviousness.

The Federal Circuit found that the proposed amendments were not improper even though some of the changes were non-substantive changes to address consistency issues. The Court pointed out that “once a proposed claim includes amendments to address a prior art ground in the trial, a patent owner also may include additional limitations to address potential § 101 or § 112 issues, if necessary.” The Court rejected American National’s argument that permitting such amendments creates an “asymmetrical” and “unfair” proceeding “by allowing the patent owner and the Board to address concerns that may be proper for [an] examination or reexamination proceeding, but that [...]

Cloudy Skies: PTO Director Finds Abuse and Sanctionable Conduct

by | Oct 13, 2022 |

The US Patent & Trademark Office (PTO) Director issued a precedential opinion finding that filing an inter partes review (IPR) solely to extract payment in a settlement—without the intent to prosecute the IPR to completion—is a sanctionable abuse of process. OpenSky Indus., LLC v. VLSI Tech. LLC, IPR2021-01064 (Oct. 4, 2022) (Vidal, Dir.)

In 2019, VLSI asserted two patents against Intel. In response, Intel filed two IPRs against the allegedly infringed patents, but both IPRs were discretionally denied by the Patent Trial & Appeal Board (Board) based on the advanced stage of the underlying litigation and overlapping issues. The suit proceeded, and a jury awarded VLSI more than $600 million in damages in 2021.

OpenSky Industries was founded two months after the judgment. OpenSky filed a “copycat” IPR petition based on Intel’s previous petitions (including refiling the declarations of Intel’s expert without his knowledge) targeting VLSI’s two allegedly infringed patents. The Board instituted over VLSI’s argument, noting that patentability issues were raised that had not been resolved in the district court case. Initially, OpenSky attempted to settle the IPRs with VLSI, but VLSI refused. OpenSky then reached out to Intel, offering to let Intel collaborate if it agreed to pay a success fee. Intel refused and later filed its own IPR petition and joinder motion. After Intel’s refusal, OpenSky pivoted back to VLSI, offering to “refuse[] to pay [the] expert for time at deposition so [the] expert does not appear at deposition” in return for payment. VLSI reported the scheme to the Board.

Intel was joined as a party to the OpenSky IPR proceeding in June 2022 based on its later-filed petition. Once Intel joined, OpenSky threatened to forego both deposing VLSI’s expert and filing its reply brief unless Intel paid it for its “prior work in the IPR” plus “additional remuneration.” Intel refused. While OpenSky did notice VLSI’s expert, it declined to file a Petitioner Reply brief, forcing Intel to draft the reply. Later, at VLSI’s request (OpenSky missed the request date), oral argument in the proceeding took place before the Board. OpenSky did not meaningfully participate.

While all this was unfolding, the Director sua sponte initiated an investigation to determine “[w]hat actions the Director . . . should take when faced with evidence of an abuse of process or conduct that otherwise thwarts . . . the goals of the Office and/or the AIA.” To begin the investigation, the Director sent discovery requests to each of the three parties. VLSI and Intel complied. OpenSky, by comparison, either incompletely complied with or directly refused each request. Based on those evasions, the Director sanctioned OpenSky for discovery misconduct, applying adverse inferences against OpenSky on each request.

Discovery sanctions in place, the Director moved to the central question: Did OpenSky abuse the IPR process? The Director answered yes.

First, the Director found that OpenSky’s conduct violated its duty of candor and good faith to the Board. In its negotiations with VLSI, OpenSky offered to deliberately sabotage its own petition to hinder Intel. In its negotiations with Intel, OpenSky did [...]

The Board Is Back in Town: Arthrex Can’t Save Untimely Motions to Terminate

by | Sep 29, 2022 |

The US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board (Board) unpatentability finding and denial of a motion to terminate, finding that the Board had already issued final written decisions that were not vacated at the time the Board denied the parties’ motion to terminate. Polaris Innovations Ltd. v. Derrick Brent, Deputy Under Secretary of Commerce for Intellectual Property and Deputy Director of The United States Patent and Trademark Office, Case No. 19-1483 (Fed. Cir. Sept. 15, 2022) (Prost, Chen, Stoll, JJ.)

Polaris owns two unrelated patents directed to computer memory. The first patent relates to improved control component configuration, and the second patent relates to a shared-resource system in which logical controls are used to manage resource requests. In 2016, Polaris filed a complaint accusing NVIDIA of infringing both patents. NVIDIA responded by filing petitions for inter partes review (IPR) against each patent. In 2017, the Board issued its final written decisions, finding the challenged claims of both patents unpatentable. Polaris appealed.

The Federal Circuit vacated the Board’s decision in view of Arthrex, Inc. v. Smith & Nephew, Inc. (Arthrex I). On remand, the Board administratively suspended the IPR proceedings pending potential Supreme Court review of Arthrex I. During the administrative suspension, Polaris and NVIDIA filed a joint motion to terminate the proceedings. While those motions were pending, the Supreme Court vacated Arthrex I, substituting an alternative remedy for violation of the Appointments Clause in United States v. Arthrex, Inc. (Arthrex II). In view of Arthrex II, the Supreme Court vacated the Federal Circuit’s vacatur of the Board’s final written decision, thus reinstating those decisions.

On remand to the Board, Polaris argued that the Board should grant Polaris’s then-pending motion to terminate. The Chief Administrative Law Judge responded that termination was not appropriate because the Supreme Court’s decision meant that the “final written decision in each of these cases is not vacated, and it is not necessary for the Board to issue a new final written decision in either of these cases.” Polaris filed a request for Director rehearing. The Director denied rehearing. Polaris appealed.

Polaris argued that the Board erred by failing to grant the joint motions to terminate filed in both proceedings before the Board on remand. Relying on 35 U.S.C. § 317, the Federal Circuit explained that motions to terminate should be granted “unless the Office has decided the merits of the proceeding before the request for termination is filed.” The Court found that the Board had already decided the merits of the cases in final written decisions that were not vacated at the time the Board made its decision denying Polaris’s motions to terminate. The Court therefore affirmed the Board’s decision that termination was inappropriate.

Polaris also raised two claim construction arguments. Polaris argued that the Board misconstrued the term “memory chip” in the IPR involving one of the challenged patents and misconstrued the term “resource tag buffer” in the IPR involving the [...]

It Can Take Three Appeals to Make a Claim Construction Go “Right”—or Three Bites by Apple

by | Sep 22, 2022 |

In a nonprecedential opinion on remand from the US Court of Appeals for the Federal Circuit and a US Patent & Trademark Office (PTO) Director-granted request for review, the Patent Trial & Appeal Board (Board) reconstrued claim terms it had previously construed in consideration of the patent specification, prosecution history and Federal Circuit construction of similar terms in a related case. Apple Inc. v. Personalized Media Communications, LLC, IPR2016-00754, IPR2016-01520 (P.T.A.B. Sept. 8, 2022) (Turner, APJ.)

In March 2016, Apple filed a petition to institute an inter partes review (IPR) against a patent (’635 patent) owned by Personalized Media Communications, LLC (PMC). After PMC filed its Patent Owner Preliminary Response (POPR), the Board instituted the IPR on some, but not all, of Apple’s requested grounds. Per Board procedure, PMC filed its Patent Owner Response (POR) and a contingent motion to amend its patent’s claims. In response, Apple filed a reply and an opposition to the contingent motion, and PMC filed a reply to Apple’s opposition. After oral argument the Board issued a Final Written Decision (754-FWD) finding all challenged claims unpatentable and denying the contingent motion to amend. PMC first sought rehearing of the Board’s decision and, after rehearing was denied, appealed the Board’s decision to the Federal Circuit.

Similarly, in July 2016, Apple filed another petition against the same PMC patent. After considering PMC’s POPR, the Board instituted an IPR on some of Apple’s requested grounds. PMC again filed a POR and a contingent motion to amend, to which Apple filed a reply and opposition (to which PMC filed its reply and Apple a sur-reply). Again, the Board held an oral hearing and issued a Final Written Decision (FWD) finding all challenged claims unpatentable and denying the contingent motion to amend. PMC again sought rehearing of the Board’s decision and, after rehearing was denied, appealed the Board’s decision to the Federal Circuit.

On appeal of each proceeding, PMC moved, and the Federal Circuit granted remand in light of and consistent with the 2021 Supreme Court decision in U.S. v. Arthrex, Inc., where a five-justice majority found that the appointment of Board administrative patent judges was unconstitutional and a seven-justice majority concluded that the remedy was to vest the PTO Director with authority to overrule Board decisions.

On remand to the PTO, PMC filed a request for director review, which the Commissioner for Patents (performing the functions and duties of the PTO Director) granted. The Commissioner’s Granting Order agreed with PMC’s argument that the Board, in these two cases, had construed the claim terms “encrypted” and “decrypted” in a manner that could include “scrambling and descrambling operations on digital information, but could also include … on analog information” and was inconsistent with the Federal Circuit’s partial reversal of the Board’s construction in yet another IPR proceeding (755-IPR regarding another related PMC patent) between Apple and PMC. As to the related patent IPR, the Federal Circuit ultimately construed “encrypted digital information transmission including encrypted information” as “… limited [...]

PTO Director Lays Out Limits on “Roadmapping” as Factor for Discretionary IPR Denials

by | Sep 15, 2022 |

Exercising its discretion under 35 U.S.C. § 314(a), the Patent Trial & Appeal Board (Board) denied institution of two inter partes reviews (IPRs) based on its understanding of its own precedential 2017 decision in Gen. Plastic Indus. Co. v. Canon Kabushiki Kaisha. US Patent & Trademark Office Director Kathi Vidal subsequently reversed the Board’s ruling in a precedential sua sponte decision clarifying how to apply the seven factors set forth in General Plastic. Code200, UAB v. Bright Data, Ltd., IPR2022-00861; -00862, Paper 18 (PTAB Aug. 23, 2022) (Vidal, Dir. of PTO).

In General Plastic, the Board addressed the practice of filing seriatim petitions attacking the same patent, where each petition raises a new ground for invalidity. The Board considers the General Plastic factors when determining whether to deny IPR institution to ensure efficient post-grant review procedures and prevent inequity. The seven factors are as follows:

  1. Whether the same petitioner previously filed a petition directed to the same claims of the same patent
  2. Whether at the time of filing of the first petition the petitioner knew of the prior art asserted in the second petition or should have known of it
  3. Whether at the time of filing of the second petition the petitioner had already received the patent owner’s preliminary response to the first petition or had received the Board’s decision on whether to institute review in the first petition
  4. The length of time that elapsed between the time the petitioner learned of the prior art asserted in the second petition and the filing of the second petition
  5. Whether the petitioner provided adequate explanation for the time elapsed between the filings of multiple petitions directed to the same claims of the same patent
  6. The finite resources of the Board
  7. The requirement under 35 U.S.C. § 316(a)(11) to issue a final determination no later than one year after the date on which the PTO Director notices institution of review.

In denying institution in this case, the Board explained that the petitioner’s failure to stipulate that it would not pursue the same grounds in district court “weigh[ed] strongly in favor of exercising discretion to deny institution and outweigh[ed] the fact that the Board did not substantively address the merits of the prior petition.” Director Vidal disagreed, reasoning that when a first petition is not decided on its merits, a follow-on petition affords a petitioner the opportunity to receive substantive consideration. Director Vidal further explained that factor 1 “must be read in conjunction with factors 2 and 3.” Application of factor 1 in a vacuum strips context from a petitioner’s challenges and creates an inappropriate bright-line rule for denying institution.

Proper application of the General Plastic factors requires consideration of the potential for abuse by a petitioner. Director Vidal noted the problem of “roadmapping” raised in General Plastic (i.e., using one or more Board decisions to create a roadmap for follow-on filings until the petitioner finds a ground that results in institution). A denial decision based solely on the [...]

Check Your Expert Skills and Standing

by | Sep 8, 2022 |

The US Court of Appeals for the Federal Circuit dismissed a portion of an appeal from the Patent Trial & Appeal Board (Board) regarding obviousness because the patentee did not have standing to challenge the decision regarding one of the claims. The Court also affirmed-in-part because the definition of person of ordinary skill in the art applied by the Board was not unreasonable or unsupported by the evidence. Best Medical International, Inc. v. Elekta Inc., Case Nos. 21-2099; -2100 (Fed. Cir. Aug. 29, 2022) (Hughes, Linn, Stoll, JJ.)

Best Medical International (BMI) owns a patent directed to a method and apparatus for conformal radiation therapy of tumors using a pre-determined radiation dose. The Board instituted two inter partes review (IPR) petitions filed by Varian Medical Systems and Elekta. During the pendency of the IPR proceeding, a parallel ex parte re-examination was ongoing. After institution of the IPRs, the examiner in the re-examination rejected claim 1, which BMI subsequently cancelled “without prejudice or disclaimer.” After BMI cancelled claim 1, the Board issued its final written decision in the IPR proceedings. The Board noted that BMI had cancelled claim 1 during re-examination, but concluded that claim 1 had “not yet been canceled by a final action” because BMI had “not filed a statutory disclaimer of claim 1.” The Board therefore considered the merits of Elekta’s patentability challenge and determined that claim 1 was unpatentable as obvious. The Board issued a split decision as to the other claims, finding one claim patentable and the others unpatentable. BMI appealed.

The Federal Circuit began by analyzing whether BMI had standing to challenge the Board’s invalidation of the now cancelled claim 1. BMI attempted to invoke Munsingwear vacatur, which allows courts to vacate underlying decisions on issues that have become moot during their pendency. As an initial matter, the Court found that the Board had the authority to invalidate the claim because it was not finally cancelled at the time the Board issued its final written decision. Regarding BMI’s vacatur argument, Elekta argued that BMI lacked standing to challenge the decision related to the cancelled claim. BMI countered that it had suffered an injury sufficient to create Article III standing because it believed that collateral estoppel might be applied by the examiner regarding other claims in another patent subject to re-examination. The Court was unpersuaded by this argument, in part because BMI could not cite any case law where collateral estoppel was applied in that fashion. The Court found that Munsingwear vacatur was inappropriate because the mooting event did not happen during the pendency of the appeal—it happened before the appeal was filed. The Court therefore concluded that BMI lacked standing to challenge the Board’s decision regarding the now cancelled claim.

Turning to the other claims the Board found unpatentable, BMI challenged the Board’s finding that a person of ordinary skill in the art must have formal computer programming experience. The Federal Circuit recited the non-exhaustive list of factors used to determine the requisite level of [...]

Not “Use It or Lose It”: Even if Unexercised, Director’s Authority over Institution Decisions Remains

by | Aug 25, 2022 |

The US Court of Appeals for the Federal Circuit denied mandamus relief, finding that a party is not entitled to petition the director for review of a Patent Trial & Appeal Board (Board) decision denying institution of an inter partes review (IPR) or post-grant review (PGR) proceeding. This ruling reflects the Court’s ongoing consideration of the Supreme Court’s decision in United States v. Arthrex, Inc., which held that Board judges cannot constitutionally render final decisions in IPRs without US Patent & Trademark Office (PTO) Director oversight. Click here for our discussion of the case on remand, for which the Federal Circuit just denied en banc rehearing. In re Palo Alto Networks, Inc., Case No. 22-145 (Fed. Cir. Aug. 16, 2022) (Dyk, Chen, JJ.) (Reyna, J., concurring).

After being sued by Centripetal Systems for patent infringement, Palo Alto Networks filed petitions for IPR and PGR of some of the asserted patents. The Board denied institution, and Palo Alto Networks filed requests for Director rehearing. Although the PTO acknowledged receipt of the request, it informed Palo Alto Networks that the Director was not considering requests for rehearing of institution decisions “at this time.” Thereafter, Palo Alto Networks sought a writ of mandamus from the Federal Circuit. Between the request for mandamus and the Court’s decision, the PTO issued guidance explaining that although the PTO was not considering requests for rehearing, “the Director has always retained and continues to retain the authority to review such decisions sua sponte after issuance (at the Director’s discretion),” and indeed, exercised its authority to initiate sua sponte review since.

The Federal Circuit rejected Palo Alto Networks’ claim that the Director’s refusal to consider petitions for rehearing of institution decisions amounted to an abdication of authority prohibited by the Appointments Clause. Even assuming that institution decisions were “final decisions on how to exercise executive power” implicating the Appointments Clause, the Court found that the Director maintains statutory and regulatory authority to review institution decisions (unlike in Arthrex), and that the Board renders such decisions only based on the Director’s delegation of authority (also unlike Arthrex). Accordingly, the structural authority maintained by the Director is sufficient, even if such authority goes unexercised, according to the Court.

Writing separately, Judge Reyna agreed that no Appointments Clause violation had occurred but on different grounds. Although Judge Reyna noted that a categorical rejection of requests for rehearing by the Director might raise constitutional concerns, he concluded that mandamus was inappropriate for several reasons. First, the Director’s caveat that she refused to accept requests “at this time” did not constitute a categorical refusal but rather an exercise of discretion. Second, the Director’s invocation of her sua sponte authority to review belied a lack of exercise of discretion. The Director did in fact exercise sua sponte authority to consider Palo Alto Networks’ request, even though briefing in the Federal Circuit was pending, and thus a writ of mandamus was inappropriate.

Prior Art Citation to Inventors’ Report Not “By Another” for § 102(e)

by | Aug 25, 2022 | ,

The US Court of Appeals for the Federal Circuit found that a prior art patent’s summarization of a report authored by the inventors of a patent challenged under inter partes review (IPR) did not constitute a disclosure “by another” under pre-America Invents Act § 102(e). LSI Corp. v. Regents of Univ. of Minnesota, Case No. 21-2057 (Fed. Cir. Aug. 11, 2022) (Dyk, Reyna, Hughes, JJ.)

The Regents of the University of Minnesota (UMN) sued LSI Corporation and Avago Technologies (collectively, LSI) for infringement of a patent related to methods for reducing errors in binary data sequences. LSI petitioned for IPR, challenging several claims of the asserted patent and arguing that they were anticipated by two prior art references, Okada and Tsang. Tsang made reference to a “Seagate Annual Report” that was published by the inventors of the asserted patent, and which was later embodied in the patent’s application.

The Patent Trial & Appeal Board (Board) found that one of the challenged claims was anticipated by Okada. The Board also found that LSI had not shown that the other challenged claims were rendered unpatentable by either Okada or Tsang and further rejected an invalidity (anticipation) theory first raised by LSI during oral arguments as untimely (while noting that the argument failed even if timely raised). The Board determined that the Tsang reference was not “by another” under § 102(e) because LSI’s petition relied solely on material that was originally disclosed in the inventor’s Seagate Annual Report. LSI appealed the Board’s determinations relating to invalidity based on Okada or Tsang.

The Federal Circuit noted that LSI did not challenge the Board’s untimeliness determination and rejected LSI’s argument that it did not need to because the Board nevertheless reached a merits decision on the argument. The Court cited to its 2016 decision in Intelligent Bio-Systems v. Illumina Cambridge, which held that “the Board’s rejection of arguments on the ground that they were newly raised in a reply brief was not an abuse of discretion even though the Board went on to address the merits.”

Turning to the § 102(e) issue, the Federal Circuit first explained that an invention is anticipated under § 102(e) if the invention is described in a patent application filed “by another,” but a patent owner may overcome such anticipation by establishing that the relevant prior art disclosure describes the owner’s invention. Describing the history of the Tsang reference and the patent under review, the Court explained that the inventors originally submitted a Seagate Annual Report to Seagate, a UMN collaborator. Tsang, a Seagate employee, received the report and quickly filed a patent application for an improvement on the methods described in the report. This application listed only Tsang as inventor and made direct reference to the Seagate Annual Report.

The Federal Circuit then addressed whether LSI’s IPR petition relied on Tsang’s improvement to the inventors’ report or simply on Tsang’s summary of the inventors’ report. The Court explained that while LSI’s petition relied on both Tsang’s summary of the [...]

Argument Forfeit in Remand Notwithstanding Modified Claim Construction

by | Aug 4, 2022 |

In the second appeal arising from an inter partes review (IPR), the US Court of Appeals for the Federal Circuit found that its revised claim construction from the first appeal did not permit the patent challenger to raise a new argument in a remand proceeding at the Patent Trial & Appeal Board (Board) since the patent owner’s response in the original proceeding had sufficiently put the challenger on notice of the claim construction that was adopted in the first appeal. Wireless Protocol Innovations, Inc. v. TCT Mobile, Inc., Case No. 21-2112 (Fed. Cir. July 19, 2022) (Prost, Taranto, Chen, JJ.)

Wireless Protocol Innovations (WPI) owns a patent related to controlling data flow in a point-to-multipoint communications system. WPI filed a district court complaint in 2015 asserting the patent against TCT. In response, TCT filed IPR petitions challenging certain claims of the patent. The petition presented three grounds of unpatentability, one of which relied on a reference by Sen. TCT’s petition did not propose constructions for any claim terms and argued that Sen taught the “grant pending absent state” limitation of the challenged patent. WPI argued that Sen failed to disclose “transitioning” between the “grant pending absent” and “grant pending” states after a “subsequent bandwidth grant,” as required by the claims. In its reply, TCT maintained that Sen taught the limitation but never argued that Sen could be readily modified to include a “grant pending absent state.” The Board found all of the challenged claims to be unpatentable on two grounds, one of which relied on Sen. WPI appealed.

The Federal Circuit reversed the Board’s decision with respect to the first ground, vacated the Board’s decision relying on Sen because the Board applied a flawed claim construction of “grant pending absent state,” and remanded the IPR for the Board to reconsider in view of the Court’s new claim construction. The Court also specifically declined to “prejudge what arguments TCT has properly preserved or should now be permitted to advance or what determinations as to Sen, Rydnell, and admitted prior art are supported by the evidence.”

On remand, the Board allowed the parties to submit additional briefing and expert testimony limited to the issue of whether Sen described operating a consumer premises equipment (CPE) in a “grant pending absent state” as interpreted by the Federal Circuit. TCT maintained its argument that Sen disclosed a grant pending absent state and argued for the first time that, in the alternative, it would have been obvious to a person skilled in the art to modify Sen to meet the limitation. The Board issued a remand decision finding the challenged claims unpatentable. Again, WPI appealed.

The Federal Circuit found that TCT had failed to preserve its new claim construction and obviousness argument and that “failure to timely assert a right or raise an argument constitutes forfeiture.” The Court explained that TCT acknowledged that it understood, prior to its reply, that WPI sought to distinguish the claimed “grant pending absent state” from Sen because Sen involved some [...]

Clarification or Raising the Bar? PTO Director Issues New Guidance for Discretionary PTAB Denials

by | Jun 30, 2022 | ,

On June 21, 2022, US Patent & Trademark Office (PTO) Director Katherine K. Vidal issued a memorandum addressing interim procedures for discretionary denials in America Invents Act (AIA)-post grant proceedings at the Patent Trial & Appeal Board (Board). In 2020, in order to minimize the potential conflict between the Board and parallel district court proceedings, the PTO designated the Board’s opinion in Apple v. Fintiv as precedential. Since Fintiv, the Board has issued several discretionary denials of institution based on parallel proceedings in district (and in some cases other administrative) courts. Director Vidal’s memo seeks to provide additional guidance on the PTO’s interpretation of Fintiv and its progeny and addresses multiple factors that were previously left to individual administrative law judge (ALJ) interpretation.

The memo includes rendering an initial evaluation of the merits of the petition. In particular, the Board will not deny institution of an inter partes review (IPR) or post-grant review (PGR) under Fintiv when a petition presents compelling evidence of unpatentability. This standard is higher than the institution standard, which requires only that “there is a reasonable likelihood that petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” While the memo does not elaborate on the evidence required to meet this compelling standard, numerous decisions were cited as illustrative. (See: e.g., Illumina Inc. v. Trs. of Columbia Univ., IPR2020-00988, Paper 20 (PTAB Dec. 8, 2020); Synthego Corp. v. Agilent Techs., Inc., IPR2022-00402, Paper 11 (May 31, 2022); Samsung Elecs. Co. v. Scramoge Tech., Ltd., IPR2022-00241, Paper 10 (June 13, 2022).)

Additionally, Director Vidal confirmed that Fintiv does not apply to parallel proceedings before the International Trade Commission nor where there has been a stipulation not to pursue the same grounds in a district court proceeding. The stipulation applies to grounds that are actually raised in the petition and any grounds that could have reasonably been raised in the petition, suggesting that there may be some dispute later in the district court proceeding about what grounds “could have reasonably been raised in the petition.”

Finally, the memo clarified the second factor of the Fintiv analysis: the speed with which the district court case may go to trial and be resolved. The Board will consider not only the scheduled trial date, but also the median time-to-trial for the particular district court, number of cases before the specific district court judge and the speed and availability of other dispositions.

Practice Note: While the standard for institution has not changed, the new compelling standard effectively ups the bar for any IPR, PGR or covered business method (CBM) proceedings where there is a parallel district court case. Prior to filing a new petition, patent challengers should objectively weigh the merits of their challenge or consider stipulating not to pursue the same invalidity grounds in the parallel district court proceeding.
