Inter Partes Review (IPR)

Ex Parte Reexamination Not Allowed After Failed IPR Challenge

by Paul Devinsky | Oct 14, 2021 | Patents

The US Court of Appeals for the Federal Circuit found that ex parte reexamination was unavailable to a challenger who repeatedly tried and failed to raise the same arguments for the same patent in a prior inter partes review (IPR) proceeding. In re: Vivint, Inc., Case No. 20-1992 (Fed. Cir. Sept. 29, 2021) (Moore, C.J.)

Vivint sued Alarm.com in 2015 for infringement of several patents. In response, Alarm requested that the Patent Trial & Appeal Board (PTAB) institute “a litany of post-issuance review proceedings,” including three separate IPR petitions directed to one of the patents. The PTAB refused to institute two of the petitions because Alarm failed show to a reasonable likelihood that it would prevail on at least one challenged claim and also refused to institute the third petition because it represented an example of “undesirable, incremental petitioning.” According to the PTAB, Alarm had “used prior Board decisions as a roadmap to correct past deficiencies” and allowing such “similar, serial challenges to the same patent” by the same challenger risked, not only harassment of patent owners, but also frustration of congressional intent behind the America Invents Act (AIA).

More than a year later, Alarm filed a request for ex parte reexamination of the patent—a request that used repackaged versions of arguments from its unsuccessful IPR petition. Despite the striking similarity between Alarm’s prior and current arguments, including two out of the four original IPR patentability questions being copied verbatim from the failed petition into the ex parte reexamination request, the PTAB found the petition raised substantial new questions of patentability and ordered reexamination. Vivint responded by seeking dismissal of the ex parte reexamination under 37 C.F.R. § 1.181, arguing that the PTAB has the authority under 35 U.S.C § 325(d) to deny the ex parte reexamination request because that statute applies to ex parte reexaminations and IPRs with “equal force.” The PTAB rejected Vivint’s request, stating that any § 1.181 petition raising a § 325(d) challenge must be filed before reexamination is ordered.

Vivint filed a second § 1.181 petition seeking reconsideration of the § 325(d) issue, arguing that it would have been impossible for Vivint to file the § 1.181 petition before ex parte reexamination was ordered. Vivint also argued that even if the PTAB lacked general authority to terminate the reexamination, it could exercise such authority under the Administrative Procedure Act (APA). Vivint also asserted that the PTAB “acted arbitrarily and capriciously by applying the same law to the same facts and reaching a different conclusion.” The PTAB rejected Vivint’s arguments and denied its second petition, finding that Vivint could have sought a waiver of the rules having to do with the required prior-to-ex parte timing of a § 1.181 petition vis-à-vis institution of ex parte reexamination. The PTAB also noted that ex parte reexamination was not inconsistent with denying the initial IPR. Ultimately, after an examiner issued a final rejection for all claims of the patent, Vivint appealed to the PTAB. The PTAB affirmed and Vivint [...]

Federal Circuit: Contractual Arbitration Agreements Don’t Bind PTAB Institution Decisions

by Paul Devinsky | Sep 16, 2021 | Patents

The US Court of Appeals for the Federal Circuit issued an order declining to intervene in inter partes review (IPR) institution decisions by the Patent Trial & Appeal Board (PTAB) and further denied a writ of mandamus to stay the PTAB’s IPR institution pending contractually required arbitration of the dispute between MaxPower and ROHM Japan. In re: MAXPOWER SEMICONDUCTOR, INC., Case No. 21-146 (Fed. Cir. Sept. 8, 2021) (Reyna, J.) (O’Malley, J., concurring in part and dissenting in part).

MaxPower owned patents directed to silicon transistor technology and licensed the patents to ROHM Japan. The license agreement contained an arbitration clause that applied to any disputes arising from or related to it—including patent validity. A dispute arose between the parties as to whether the patents covered certain silicon carbide transistor ROHM products. After MaxPower notified ROHM that it was initiating arbitration under the terms of their license agreement, ROHM challenged the validity of four MaxPower patents at the PTAB, which granted ROHM’s petitions to institute IPRs for the four challenged patents.

MaxPower appealed the PTAB’s institution decision to the Federal Circuit and sought a writ of mandamus to stay or terminate the IPR proceedings without prejudice to later institution if an arbitrator decided that IPR proceedings were appropriate.

The Federal Circuit held that the PTAB’s decision to institute IPR is non-appealable under 35 U.S.C. §314(d), which plainly “confirms the unavailability of jurisdiction” for the Court to hear direct appeals. The Court also found that MaxPower failed to meet the criteria necessary to invoke the collateral order doctrine, which allows appeals from interlocutory rulings if they decide an issue “separate from the merits of the case” that would not be reviewable after final judgment. The Court noted that MaxPower could still raise its arbitration-related challenges after the PTAB issued its final written decisions in these cases.

The Federal Circuit also rejected arguments that the appeals were authorized under 9 U.S.C. § 16(a)(1) and that MaxPower failed to show that its mandamus petition was not “merely a ‘means of avoiding the statutory prohibition on appellate review of agency institution decisions,’” citing the Court’s 2018 decision in In re Power Integrations.

Since the PTAB is not bound by private contracts enforcing arbitration agreements between parties, the Federal Circuit ruled that MaxPower had failed to show that the PTAB’s institution decisions in this case “clearly and indisputably exceeded its authority,” also stating that 35 U.S.C. § 294 does not authorize the PTAB to enforce private arbitration agreements.

In a partial dissent, Judge Kathleen O’Malley argued that the majority decision casts “a shadow over all agreements to arbitrate patent validity” and goes against strong federal policy in favor of enforcing arbitration agreements. While concurring with the majority that the PTAB’s IPR institution decisions are not appealable, Judge O’Malley stated that the case “provides exactly the sort of extraordinary circumstances under which mandamus review is appropriate” in what she called an important issue of first impression. The Supreme Court of the United States has held that [...]

The Application of “Authentication by Comparison” at the PTAB

by April E. Weisbruch | Aug 26, 2021 | Patents

Directly addressing the application and operation of the Federal Rules of Evidence in proceedings before the Patent Trial & Appeal Board (Board), the US Court of Appeals for the Federal Circuit affirmed-in-part and reversed-in-part two inter partes review (IPR) decisions, criticizing the Board’s refusal to consider a particular reference relied upon by the patent challenger on the basis of failure to authenticate. Valve Corp. v. Ironburg Inventions Ltd., U.S. Federal Circuit Court of Appeals Nos. 20-1315, -1316, -1379 (Fed. Cir. Aug. 17, 2021) (Dyk, J.)

The Board found that an IPR petitioner, Valve Corporation, failed to show that several challenged patents were unpatentable based on a non-authenticated copy of a critical prior art reference (the Burns article). The Burns article was a printed copy of a 2010 online review of an Xbox 360 controller. Simon Burgess, a co-inventor of the patents at issue, had facilitated the publication of the Burns article by providing a test controller to Dave Burns (who worked for an online gaming magazine) for promotional purposes. Valve appealed the Board’s decision.

Valve argued that the Burns article copy submitted in connection with the IPR (the Exhibit) was merely a printout of the same online article cited and enclosed in the prosecution histories of the challenged patents, as well as another of Ironburg’s patents directed toward similar subject matter. The Board concluded that Valve failed to show that the Exhibit was the same version of the Burns article that appeared in the prosecution history and that it was not obligated to compare the documents in the absence of testimony from Valve that the two were identical. Valve appealed.

In reviewing the Board’s decision, the Federal Circuit first referred to the principles of authentication by comparison under Fed. R. Evid. 901(b)(3), which permits authentication of a document by a comparison with an authenticated specimen “by an expert witness or the trier of fact.” While the Court did note a discrepancy in the dates shown in the Exhibit and in the Burns article in one of the prosecution histories, the Court found that the difference in dates did not bear on the subject matter being disclosed, which was “virtually identical” between the two, as well as identical to the version of the same article in the other two relevant file histories. The Court held that the Board was obligated to perform this comparison and erred by failing to do so.

After determining that the Exhibit was “substantively the same” as the versions of the Burns article from the relevant prosecution file histories, the Court addressed the question of whether the Exhibit was a printed publication under 35 U.S.C. § 102(a)(1). The Board found “overwhelming evidence” that the Burns article was accessible prior to the critical date of the patents at issue, based in significant part on the fact that Mr. Burgess had provided a controller to Mr. Burns with the purpose of a “dialogue with the intended audience,” an indicia of public accessibility. The Board also noted its agreement with [...]

Objective Indicia of Nonobviousness for Design Patents: Same Nexus Requirement as Utility Patents

by Paul Devinsky | Aug 26, 2021 | Patents

The US Court of Appeals for the Federal Circuit reversed two decisions by the Patent Trial & Appeal Board (Board), finding that a soup company and soup dispenser manufacturing company failed to prove the unpatentability of two design patents covering can dispensers. The Court also concluded that the analysis for objective indicia of nonobviousness for utility patents also applies to design patents. Campbell Soup Co. v. Gamon Plus, Inc., Case Nos. 20-2344, 21-1019 (Fed. Cir. Aug. 19, 2021) (Moore, J.)

Gamon Plus owns two design patents directed to “the ornamental design for a gravity feed dispenser display,” or a can dispenser. Gamon’s commercialized embodiment is called the iQ Maximizer gravity feed dispenser. For nearly a decade, Gamon sold tens of millions of dollars’ worth of its iQ Maximizer to Campbell Soup. Campbell attributed increased soup sales in part to the iQ Maximizer in its 10-K Securities and Exchange Commission reports (an industry publication) and in an internal marketing study. Campbell later began purchasing similar gravity feed dispensers from Trinity Manufacturing.

Gamon sued Campbell and Trinity for design patent infringement. Campbell and Trinity then petitioned for inter partes review (IPR) of Gamon’s patents. In its final written decisions, the Board found that Campbell and Trinity failed to prove unpatentability because the prior art was not similar enough to the claimed designs to constitute a proper primary reference. Trinity (Campbell) appealed.

In that appeal, the Federal Circuit disagreed, vacated and remanded. On remand, the Board again held that Campbell and Trinity failed to prove unpatentability, finding that the claimed designs would not have been obvious over the prior art. The Board reasoned that although the prior art alone had the same overall visual appearance as the claimed designs, there existed objective indicia of nonobviousness, including Gamon’s commercial success in selling iQ Maximizers to Campbell, Campbell’s praise of—and commercial success in—using the iQ Maximizer and Trinity’s copying of the iQ Maximizer. The Board presumed a nexus between those objective indicia evidences and the claimed designs because it found the iQ Maximizer to be coextensive with the claims, meaning that the product was essentially the disclosed invention with unclaimed features being insignificant. The Board also found that Gamon established such a nexus regardless of the presumption. Campbell and Trinity again appealed.

Again the Federal Circuit reversed, concluding that the claimed designs would have been obvious over the prior art. In doing so, the Court confirmed the Board’s finding that the prior art and the claimed designs shared the same overall visual appearance (which Gamon did not challenge) but found that the Board’s presumption of nexus and finding of a nexus-in-fact between the claimed designs and the evidence of commercial success and praise were not supported by substantial evidence. As for the presumption, the Court considered whether the iQ Maximizer was coextensive with the claimed invention. Nexus is presumed if the objective indicia evidence is tied to a specific product that is “coextensive” with the claimed invention. The Board recognized that the claimed portions of [...]

When it Comes to Method of Use Claims, Preamble Language Regarding Intended Use is Limiting

by Paul Devinsky | Aug 26, 2021 | Patents

The US Court of Appeals for the Federal Circuit issued three separate but related rulings (two precedential, one non-precedential) affirming decisions by the Patent Trial & Appeal Board (Board) regarding the validity of nine US patents and addressing the limitations of preamble language and motivation to combine. Eli Lilly Co. v. Teva Pharmaceuticals, Case Nos. 20-1876, -1877, -1878 (Fed. Cir. August 16, 2021) (Lourie, J.); Teva Pharmaceuticals v. Eli Lilly Co., Case Nos. 20-1747, -1748, -1750 (Fed. Cir. August 16, 2021) (Lourie, J.); Teva Pharmaceuticals v. Eli Lilly Co., Case Nos. 20-1749, -1751, -1752 (Fed. Cir. August 16, 2021) (Lourie, J.). These decisions come as the latest events in a dispute between Teva and Eli Lilly Company over competing products for the treatment of migraine headaches.

Teva owns nine patents directed to humanized antagonist antibodies that target calcitonin gene-related peptide. In 2018, the Food and Drug Administration (FDA) first approved Teva’s version of the biologic fremanezumab (Ajovy®) and then approved Lilly’s biologics license application for galcanezumab (Emgality®) eight days later. Both drugs are part of a new class of migraine therapeutic agents called calcitonin gene-related peptide antagonists.

Lilly challenged the validity of Teva’s nine patents covering Ajovy® in a series of inter partes review (IPR) petitions, arguing that the claims were obvious. The Board instituted IPR for all nine Teva patents. The similarity of subject matter and arguments led to three separate written opinions, each addressing three of the patents. In these decisions, the Board upheld the validity of three of the patents at issue (which covered methods of treating migraines with the antibodies) but found the claims of the six other patents directed to the antibodies themselves invalid.

Lilly appealed the first Board ruling covering methods of treating migraines to the Court. Lilly argued that the Board erred by (1) “reading a result into the constructions of the preambles and the term ‘effective amount,’” which led the Board to erroneously require Lilly to prove that a skilled artisan would have had “a reasonable expectation of achieving a result that was not claimed,” and (2) applying a too-high standard when weighing evidence to determine whether a skilled artisan would have a reasonable expectation of success. Lilly contended that a claim preamble containing only a statement of purpose cannot be a claim limitation and that no weight should have been given to the preambles. Teva argued that Lilly was basing its analysis on a false dichotomy between “limiting preambles” and preambles that are mere statements of purpose.

The Federal Circuit found the claim preambles to be limiting, reasoning that claims directed to methods of using compositions “are not directed to what the method ‘is’” but rather to “what the method ‘does,’” which usually is recited in the preamble. The preambles provided the only metric by which one practicing the claim could determine whether the amount administered is an “effective amount” and provided the antecedent basis for at least one later claim term in the independent claims.

After finding the preambles to [...]

As Due Process Recognizes, it’s Hard to Shoot at a Moving Claim Construction Target

by McDermott Will & Emery | Aug 5, 2021 | Patents

The US Court of Appeals for the Federal Circuit vacated several Patent Trial & Appeal Board (PTAB) decisions as violating due process and the Administrative Procedure Act (APA), referencing the parties’ inability to respond to the PTAB’s sua sponte construction of a term on which the parties had previously agreed. Qualcomm Inc. v. Intel Corp., Case Nos. 20-1589; -1594 (Fed. Cir. July 27, 2021) (Moore, C.J.)

After Qualcomm sued Intel over a patent directed to techniques for generating a power tracking supply voltage for a circuit that processes multiple radio frequency signals simultaneously, Intel filed six inter partes review (IPR) petitions challenging the validity of Qualcomm’s patents. In each petition, Intel proposed that the claim term “a plurality of carrier aggregated transmit signals” meant “signals for transmission on multiple carriers at the same time to increase the bandwidth for a user.” Qualcomm proposed a different construction: “signals from a single terminal utilizing multiple component carriers which provide extended transmission bandwidth for a user transmission from the single terminal.” Neither party disputed that the signals were required to increase user bandwidth, either at the PTAB or in a parallel proceeding before the US International Trade Commission (USITC) where the USITC adopted a construction—including the increased bandwidth requirement.

However, during the oral hearing, one of the administrative patent judges (APJs) asked Intel counsel about the inclusion of the bandwidth limitation in the claim construction. No other APJ raised, or asked Qualcomm, any questions about the increased bandwidth requirement in the claim construction. The day after the hearing, the PTAB sua sponte ordered additional briefing on the meaning of other claim terms that had been extensively discussed at the hearing.

The PTAB ultimately issued six final written decisions concluding that all challenged claims were unpatentable. In doing so, the PTAB omitted any requirement that the signals increase or extend bandwidth in construing the term “a plurality of carrier aggregated transmit signals” to mean “signals for transmission on multiple carriers.” The PTAB also held that “means for determining a single power tracking signal” (power tracker limitation) was a means-plus-function limitation and that an integrated circuit (IC) board, the “power tracker 582,” was the corresponding structure.

Qualcomm timely appealed, arguing that 1) it was not afforded notice of, or an adequate opportunity to respond to, the PTAB’s construction of “a plurality of carrier aggregated transmit signals” and 2) that the PTAB’s construction of the power tracker limitation was erroneous for failing to include an algorithm in the corresponding structure.

NOTICE AND OPPORTUNITY TO RESPOND TO THE PTAB’S CONSTRUCTION

The Federal Circuit has discussed the administrative and notice requirements provided by the APA and due process in IPR proceedings: “[a] patent owner in [an IPR] is undoubtedly entitled to notice of and a fair opportunity to meet the grounds of rejection” (Belden v. Berk-Tek). The Court observed that for IPRs, the PTAB must “timely inform” the patent owner of “the matters of fact and law asserted” and, in terms of notice, “must provide ‘all interested [...]

Even Judges Have a Boss: PTAB Must Sufficiently Articulate its Obviousness Reasoning

by Paul Devinsky | Jul 29, 2021 | Patents

Addressing the sufficiency of the Patent Trial & Appeal Board’s (PTAB) justification of its inter partes review (IPR) determination, the US Court of Appeals for the Federal Circuit reversed the PTAB’s obviousness determinations, concluding that the PTAB’s findings regarding motivation to combine were not supported by substantial evidence. Chemours Company FC, LLC v. Daikin Industries, Ltd., Daikin America, Inc., Case No. 20-1289, -1290 (Fed. Cir., July 21, 2021) (Reyna, J.) (Dyk, J., concurring in part and dissenting in part).

Chemours, owner of the challenged patents, appealed the PTAB’s final written decisions in two IPRs initiated by Daikin. The challenged claims relate to a unique polymer for insulating communication cables formed by pulling wires through melted polymer to coat and insulate the wires, a process known as “extrusion.” The challenged claims of the patents recite that the polymer has a specific melt flow range of about 30+/- g/10 mins. The polymer’s melt flow range correlates with how fast the melted polymer can flow under pressure during extrusion. A higher melt flow rate means a faster coating of the polymer onto a wire. During the IPRs, the PTAB found all challenged claims unpatentable as obvious.

The Federal Circuit reviews the PTAB’s legal determinations de novo and its factual findings for substantial evidence, which “requires more than a ‘mere scintilla’ and must be enough such that a reasonable mind could accept the evidence as adequate to support the conclusion.” Obviousness is a question of law necessarily made on underlying findings of fact, and in making factual findings, the PTAB “must have both an adequate evidentiary basis for its findings and articulate a satisfactory explanation for those findings.”

In this instance, the Federal Circuit found that the PTAB’s obviousness findings were not supported by substantial evidence. According to the Court, while the PTAB may rely on prior art other than the references being applied or combined to inform itself of the state of the art at the time of the invention, the scope of the relevant prior art encompasses only that which is “’reasonably pertinent to the particular problem with which the inventor was involved.”’ Here, the Court explained that the only prior art reference relied on was not appropriate because it expressly taught away from the claimed invention and relied on teachings from other references that were not concerned with the particular problems the prior art sought to solve. As the Court noted, the PTAB “did not adequately grapple with why a skilled artisan would find it obvious to increase [the reference’s] melt flow rate to [the] claimed range while retaining its critical ‘very narrow molecular-weight distribution.’” To support its obviousness conclusion, the PTAB needed “competent proof showing a skilled artisan would have been motivated to, and reasonably expected to be able to, increase the melt flow rate of [the reference’s] polymer to the claimed range when all known methods for doing so would go against [the reference’s] invention by broadening molecular weight distribution.” By failing to provide its reasoning, the PTAB relied [...]

Emmy Award to the Rescue – Secondary Considerations Overcome Prior Art

by McDermott Will & Emery | Apr 30, 2020 | America Invents Act

The Patent Trial and Appeal Board (Board), in a decision designated as precedential, found that a Patent Owner’s substitute claims were patentable in view of evidence of secondary considerations even though the prior art weighed in favor of obviousness. Lectronics, Inc. v. Zaxcom, Inc., Case No. IPR2018-01129 (PTAB Jan. 24, 2020) (Deshpande, APJ.) (designated precedential on Apr. 14, 2020).
