Invoking Generic Need for Claim Construction Won’t Avoid § 101 Dismissal

The US Court of Appeals for the Federal Circuit affirmed the dismissal of a patent infringement suit on § 101 grounds, rejecting the patentee’s argument that claim construction or discovery was required before assessing patent eligibility. Trinity Info Media, LLC v. Covalent, Inc., Case No. 22-1308 (Fed. Cir. July 14, 2023) (Stoll, Bryson, Cunningham, JJ.)

Trinity Info Media sued Covalent for infringement of patents related to poll-based networking systems that connect users in real time based on answers to polling questions. Covalent moved to dismiss, arguing that the patent claims were invalid under 35 U.S.C. § 101 because they were directed to patent-ineligible subject matter. In resolving the motion, the district court found that the claims were directed to the abstract idea of “matching users who gave corresponding answers to a question” and did not contain an inventive concept. The district court further found that the purported invention did not improve computer functionality but simply used “generic computer components as tools to perform the functions faster than a human would.” Accordingly, it found the asserted claims invalid under § 101 and granted the motion to dismiss. Trinity appealed.

Trinity argued that the district court erred by granting the motion without first allowing fact discovery and conducting claim construction. The Federal Circuit disagreed, finding that in order to overcome a motion to dismiss on § 101 grounds, “the patentee must propose a specific claim construction or identify specific facts that need development and explain why those circumstances must be resolved before the scope of the claims can be understood for § 101 purposes.” Trinity had identified claim terms to the district court, but never proffered any proposed constructions or explained how construction would affect the § 101 analysis. Because Trinity did not identify specific facts to be discovered or propose any particular claim construction that would alter the § 101 analysis, Trinity’s generic arguments were insufficient to avoid the motion to dismiss.

The Federal Circuit went on to analyze whether the asserted claims were invalid under the two-step framework established by Mayo and Alice. Under this framework, Step 1 evaluates whether the asserted claims are directed to a patent-ineligible concept, such as an abstract idea. Step 2 searches for an “inventive concept” by considering the claims to determine whether any elements “transform the nature of the claim” from ineligible subject matter into a patent-eligible application.

At Step 1, the Federal Circuit concluded that the claims were directed to the patent-ineligible abstract idea of “matching based on questioning.” The Court noted that a “telltale sign of abstraction is when the claimed functions are mental processes that can be performed in the human mind or using a pencil and paper” (citing Personal-Web), finding that the “human mind could review people’s answers to questions and identify matches based on those answers.” Further, the trivial variations appearing in some claims (e.g., using a handheld device, reviewing matches by swiping and matching based on gender) did not change the focus of the asserted claims. The Court explained that for software inventions, Step 1 [...]

Reissue Boat Won’t Float: “Original Patent” Rule Sinks New Floating Grill Claims

Addressing the same invention requirement for reissue patents, the US Court of Appeals for the Federal Circuit affirmed a Patent Trial & Appeal Board decision to reject an overly broad reissue application. In re Float‘N’Grill LLC, Case No. 22-1438 (Fed. Cir. July 12, 2023) (Prost, Linn, Cunningham, JJ.)

Float‘N’Grill (FNG) owned a patent directed to a floating device that supports a grill so that users can grill food while in water. The patent’s specification lays out a single embodiment, illustrated in Figure 1 below, which includes a float (20) that has two supports (46, 48), each of which “includes a plurality of magnets” (60) so that the grill can be removably attached to the float:

FNG filed a reissue application that claimed new ways to “more generically” removably attach a grill to the float. In rejecting the reissue claims, the Examiner found that three of the new requested claims required zero magnets, three claims required one magnet, and one claim did not specifically require magnets but referred to a magnet in the preamble. This was in contrast to the issued patent’s only embodiment, which required multiple magnets. The Examiner, therefore, rejected the reissue claims for failure to meet the “original patent” requirement of 35 U.S.C. § 251. The Board affirmed. FNG appealed.

The question on appeal was whether FNG’s newly requested claims complied with § 251. The Federal Circuit explained that the only path to expanding the coverage of an issued patent is through a reissue application, which is subject to § 251’s limitations. Pertinent here, § 251 requires reissue claims to be directed to the same invention disclosed in the original patent. Citing Supreme Court and Federal Circuit decisions, the Court described the “original patent” requirement as a question of whether the issued patent’s disclosed invention “on its face, explicitly and unequivocally describe[s] the invention as recited in the reissue claims.”

Turning to FNG’s reissue claims, the Federal Circuit agreed with the Board, finding that the new claims were not directed to the same invention as the original patent and thus failed to satisfy § 251. The Court explained that the specification of FNG’s issued patent had just one embodiment, which featured “a plurality of magnets” to removably attach a grill to the floating device. The reissue claims, however, contemplated more general attachments without magnets.

FNG argued that its claims were acceptable under § 251 because the magnets were a “non-essential embodiment” of the invention. The Federal Circuit disagreed for four reasons:

  1. An element of a patent may be deemed essential even if the patent does not explicitly state as much. Thus, the magnets were essential to FNG’s original patent, even if not labeled so.
  2. It is irrelevant that a person of skill in the art may know to replace an original patent element with “some other undisclosed mechanism” to reach the same result. Here, a new way to attach a grill to the [...]

Hit a Nerve? Obviousness Inquiry Must Address Claims at Issue

The US Court of Appeals for the Federal Circuit vacated and remanded a Patent Trial & Appeal Board non-obviousness decision, finding that the context of the proposed combination of prior art in the Board’s obviousness inquiry was not directed toward the context of the claim at issue. Axonics, Inc. v. Medtronic, Inc., Case No. 21-1451 (Fed Cir. July 10, 2023) (Lourie, Dyk, Taranto, JJ.)

Axonics filed petitions for inter partes review (IPR) challenging the validity of two patents owned by Medtronic as obvious. During the IPRs, the Board analyzed two prior art references, an article titled, “Electrical Stimulation of the Trigeminal Nerve Root for the Treatment of Chronic Facial Pain” by Ronald Young and a patent assigned to Gerber. The Medtronic patents described percutaneously positioning a lead to stimulate the sacral nerve. By contrast, Gerber described positioning an electrode in the sacral nerve region in a non-percutaneous way, and Young described positioning an electrode percutaneously to stimulate the trigeminal sensory root. The Board found that Medtronic’s patents were not obvious over Young in view of Gerber because of lack of motivation to combine the two prior art references. The Board also noted “that the proposed combination ‘would not be feasible in the trigeminal nerve region.’” Axonics appealed.

The Federal Circuit found that the Board erred in conducting the obviousness analysis. The Board’s proposed analysis centered on Young’s trigeminal sensory root context, not the Medtronic patents’ sacral nerve context. First, the Board questioned whether motivation to use the resulting combination of Young and Gerber existed in the trigeminal nerve context, but not in Medtronic patents’ sacral nerve context. Second, the Board found “that the relevant art [of the Medtronic patents] is medical leads specifically for sacral neuromodulation.”

Addressing the first error, the Federal Circuit explained that the prior art combination must be directed toward meeting the requirement of the claimed patent, not the requirement of the first prior art. The Court found that the Board did not conduct this analysis. Addressing the second error, the Court noted that “the relevant art” of the Medtronic patents was not “limited to medical leads for sacral-nerve stimulation.” The Court examined the specification of the patent as well as its claim and ruled that the scope of the Medtronic patents was broader than what the Board concluded.

The Court found that the Board’s errors were not harmless since the Board relied on these errors in rejecting Axonics’s obviousness arguments and provided no other reason for concluding Medtronic’s claims were not obvious. Therefore, the Court vacated the Board’s decision and remanded for further consideration.

Practice Note: In considering obviousness arguments under 35 U.S.C. § 103, keep in mind the difference between the claim at issue and the considered combination of prior art. The scope of the claim also needs to be considered based on the entirety of the patent.

Woohyeong Cho, a summer associate in the Washington, DC, office, also contributed to this case note.

Speculative Injury from Rulemaking Petition Denial Doesn’t Confer Standing

The US District Court for the District of Columbia affirmed the dismissal of a case alleging that the US Patent & Trademark Office (PTO) violated the Administrative Procedure Act (APA) by denying the plaintiffs’ rulemaking petition. The district court found that the plaintiffs’ alleged injury was too speculative to confer Article III standing. US Inventor, Inc. v. US Patent and Trademark Office, Case No. 22-2218 (D.D.C. July 12, 2023) (Bates, J.)

Under the America Invents Act (AIA), the Patent Trial & Appeal Board may hear challenges to the validity of patents through inter partes review (IPR) and post-grant review (PGR). The decision to initiate a review is made at the discretion of the PTO on a case-by-case basis. US Inventor, Inc., and National Small Business United (collectively, NSBU) filed a rulemaking petition with the PTO, arguing that the PTO unlawfully designated cases as precedential or informative without putting those considerations through notice-and-comment rulemaking, as required by the APA. NSBU expressed the same position in a previous lawsuit filed in the Eastern District of Texas that was dismissed for lack of standing—a decision upheld by the US Court of Appeals for the Fifth Circuit. NSBU subsequently filed a lawsuit in the District of Columbia. The PTO filed a motion to dismiss for lack of standing.

In a motion to dismiss, a court will accept facts alleged in the complaint as true but will not assume the truth of legal conclusions. The District of Columbia noted that not every denial of a rulemaking petition confers standing on the petitioner. Standing is established by claiming an injury in fact that can be traced to the defendant’s actions and is likely to be redressed by the court. Therefore, a plaintiff must show that the denial of the petition caused a concrete injury in fact. Injury in fact must be concrete, particularized and not conjectural or hypothetical. Standing can be established via associational standing or organizational standing. Here, the court found that NSBU could establish neither.

In finding no associational standing, the District of Columbia agreed with the PTO that NSBU’s theory of injury was too speculative and not concrete. NSBU proposed an “uncertain series of events” that could lead to an alleged injury, but the court rejected the claim as attenuated conjecture based on the actions of independent third parties (similar to the fact pattern in the Supreme Court’s 2013 decision in Clapper v. Amnesty Int’l USA.)

The District of Columbia heavily criticized the first step of NSBU’s proposed series of events, which was that a valid IPR or PGR would have to be filed on behalf of a patent held by a member of NSBU’s organizations. The court found that identifying potential members that might face IPR or PGR proceedings if a third party decided to bring a claim against them was too hypothetical and relied entirely on the actions of a third party.

The District of Columbia also disagreed with NSBU’s reliance on statistics. NSBU argued that patent cancellation is more likely [...]

Federal Circuit to Revisit Whether KSR Extends to Design Patents

Granting a petition for rehearing en banc, the US Court of Appeals for the Federal Circuit decided to revisit the effect of the Supreme Court’s 2007 decision in KSR International v. Teleflex on design patents. LKQ Corporation v. GM Global Technology Operations, Case No. 21-2348 (Fed. Cir. June 30, 2023) (per curiam). The Federal Circuit withdrew its earlier panel decision addressing KSR’s application to design patents.

This case arose from an inter partes review (IPR) filed by LKQ against GM alleging that GM’s design patent for a vehicle fender was obvious and/or anticipated. In its original opinion, the Federal Circuit applied its predecessor court’s design patent test for obviousness in In re Rosen (CCPA 1982), as well as its decision in Durling v. Spectrum Furniture (Fed. Cir. 1996), ultimately finding that GM’s design patent was not obvious or anticipated and affirming the Patent Trial & Appeal Board’s decision. The Federal Circuit determined that it was unclear whether the Supreme Court had overruled Durling and Rosen with KSR, so it did not apply KSR. Judge Lourie provided an additional opinion that KSR did not overrule Rosen. Judge Stark concurred in the judgment but found that LKQ had forfeited its argument that KSR overruled Rosen.

In its order for en banc review, the Federal Circuit asked the parties to address whether KSR abrogates Rosen and Durling and whether KSR applies to design patents regardless of whether it overrules or abrogates Rosen and Durling. Specifically, the Court inquired whether KSR’s “expansive and flexible approach” means that Durling’s two requirements should be modified or eliminated. Durling’s first requirement is that “[b]efore one can begin to combine prior art designs . . . one must find a single reference, ‘a something in existence, the design characteristics of which are basically the same as the claimed design.’” Its second requirement is that secondary references “may only be used to modify the primary reference if they are ‘so related to the primary reference that the appearance of certain ornamental features in one would suggest the application of those features to the other.’”

The Federal Circuit also asked the parties to address the appropriate test for evaluating the obviousness of design patents in the event the Rosen-Durling test was to be eliminated or modified.

The Federal Circuit further requested that the parties address whether eliminating the Rosen-Durling test would cause uncertainty in a settled area of law. Finally, the Court asked whether any differences between design patents and utility patents are relevant to the design patent obviousness inquiry.

The Federal Circuit indicated that the issues of anticipation and forfeiture from the initial appeal were preserved, but that additional briefing on those issues was not required. The Court invited the United States to participate as amicus curiae.

Practice Note: With the Federal Circuit granting rehearing en banc, there is a possibility that the Court may extend the obviousness analysis of KSR to design patents.

Coons and Tillis Introduce Two Bills Intended to Change Patent Landscape

In late June 2023, Senators Chris Coons (D-DE) and Thom Tillis (R-NC) introduced two bills in Congress that, if enacted, would change the patent adjudication landscape:

The PREVAIL Act is essentially a reintroduction of the previously unsuccessful STRONGER Patents Act of 2019 bill and would change fundamental aspects of how the Board operates. Under current practice, the Board judges who rules on institution and also decides the outcome of an instituted proceeding. Under the PREVAIL Act, institution decisions would be made by a separate set of judges from those that render a decision on a petition’s merits. Through proposed changes to the initiation and estoppel provisions, a patent challenger could bring its attack on patent validity in either the district court or the Board, but not both. And as part of the harmonization of district court and Board proceedings, the PREVAIL Act would adopt the “clear and convincing” standard for Board review and codify existing Board practice of applying the same claim construction standard as district courts apply.

The PREVAIL Act would also change who can bring issues to the Board by imposing standing and revised real-party-in-interest requirements. An IPR petitioner would have to establish standing equivalent to that required for a district court declaratory judgment action. Moreover, anyone who financially contributes to an IPR would be deemed a real party in interest to avoid multiple petitions backed by the same entity. To reduce the multiplicity of proceedings, the PREVAIL Act would establish a presumption against a joinder for time-barred petitions. The PREVAIL Act also includes several provisions directed to the independence and transparency of the Board’s decision-making, including establishing a code of conduct and requiring recordation of the Director’s actions that affect Board proceedings.

Turning to subject matter eligibility, the Patent Eligibility Restoration Act would overrule Supreme Court decisions importing a judicial exception to Section 101 and would codify many of the existing categories of ineligible subject matter, including mathematical formulae; substantially economic, financial, social, cultural and artistic practices (in other words, fundamental human activity); natural processes and products made independent of human activity; and mental processes. The Patent Eligibility Restoration Act specifically would authorize early resolution and limited discovery on Section 101 ineligibility.

Practice Note: Although both acts have been introduced before without much success, Congress’s present focus on technology (such as artificial intelligence) may serve to propel one or both bills forward. Of course, it remains to be seen whether Congress has an appetite for modifying patent law, particularly in the lead-up to an election year.

Amending a Range? Better Enable It

In a post-grant review appeal, the US Court of Appeals for the Federal Circuit explained that patent claims reciting a range must enable the full scope of that range and, under the Administrative Procedure Act (APA), the Patent Trial & Appeal Board is not bound to decisions rendered in a Preliminary Guidance. Medytox, Inc. v. Galderma S.A., Case No. 22-1165 (Fed. Cir. June 27, 2023) (Dyk, Reyna, Stark, JJ.)

Medytox owns a patent directed to the use of animal-protein-free botulinum toxins with long-lasting effects. Galderma challenged the validity of Medytox’s patent in a post-grant review. In response to the challenge, Medytox filed a motion to amend the patent under the Board’s Pilot Program, which allows a petitioner to amend the patent claims and receive a preliminary decision as to whether the amendment would preserve the patent’s validity (Preliminary Guidance). Medytox proposed modifying the claims so that they only encompassed treatment methods that possessed a patient response rate of “50% or greater.” Galderma opposed the motion, arguing that claiming a 50% to 100% response rate constituted new matter, meaning the claim language improperly claimed an invention that was not described in the patent application as filed.

The Board issued a Preliminary Guidance construing the new claim language and explaining that it did not believe that Medytox’s amended claims represented new matter. According to the Board, the new limitation did not “necessarily” claim a range of 50% to 100% and instead could just be claiming 50% or greater. The Board explained that since the patent contained the concept of a greater than 50% response rate, claiming that rate was not new matter. As a consequence of the Board’s positive reception, Medytox amended all the claims to include the new language. Galderma once again opposed the motion and further argued that the amended claims were not enabled. The Board held an oral hearing and questioned the parties on the proper construction of the “50% or greater” claim language.

In its final written decision, the Board decided that the limitation was a range of 50% to 100%, contrary to its statement in the Preliminary Guidance. Because the claimed limitation was a range, the Board—citing the Supreme Court’s 2023 decision in Amgen v. Sanofi and the Federal Circuit’s 2012 decision in Magsil v. Hitachi Global Storage—explained that the entire range must be enabled. The patent, however, only described a response rate of up to 62%, so the Board found that the claimed range was not enabled. Medytox appealed.

Medytox alleged three errors. First, Medytox argued that the Board’s new construction was wrong. Second, Medytox argued that the claims were enabled. Finally, Medytox argued that the Board violated the APA by capriciously departing from its Preliminary Guidance. The Federal Circuit rejected Medytox’s arguments and affirmed the Board’s decision.

First, the Federal Circuit determined that there was no meaningful difference between the two possible constructions—claiming a response rate greater than 50% was essentially the same as claiming a response rate of [...]

Not on the Merits: Claim Preclusion Doesn’t Bar Inducement Claims After Direct Infringement Case

Applying Seventh Circuit law to determine whether the dismissal of patent infringement claims should be upheld on the basis of claim preclusion, the US Court of Appeals for the Federal Circuit reversed a district court ruling that the claims were precluded by res judicata. Inguran, LLC v. ABS Global, Inc., Case No. 22-1385 (Fed. Cir. July 5, 2023) (Lourie, Bryson, Reyna, JJ.)

At the district court, ABS argued that a previous infringement suit brought by Inguran precluded it from bringing the instant suit. At issue was whether the previous suit asserting direct infringement of Inguran’s “GSS technology” used to create “single-sexed semen straws” barred the current suit, which alleged that ABS induced third parties to infringe upon the same technology by entering into licensing agreements with these third parties. The district court agreed with ABS. Inguran appealed.

To successfully assert claim preclusion under Seventh Circuit law, a party must meet the following three-factor test:

  1. An identity of the parties or their privies in the first and second lawsuits
  2. An identity of the cause of action
  3. A final judgment on the merits in the first suit.

The Federal Circuit’s analysis focused on the second requirement. In determining whether there was an identity of the cause of action, the Court examined whether the second claim was based on the same set of transactional facts as the earlier litigation between the parties. In patent infringement cases, the general rule is that res judicata does not bar the assertion of new rights acquired during the previous action, which could have been litigated but were not (i.e., claims that arose while the litigation was ongoing but after the original complaint was filed).

The Federal Circuit determined that the transactional facts between the present case and the previous litigation were different because the cases respectively centered around theories of induced infringement by third parties and direct infringement. As the Court noted, “The evidence needed to support these two claims (induced infringement vs direct infringement) is different.” To allege and prove induced infringement, Inguran needed to establish additional facts beyond what it asserted in the previous case to show direct infringement. As the Court noted, an “induced infringement claim rests on evidence and elements beyond those required by direct infringement.” Although minimal evidence regarding the activities of the third parties was part of the record in the previous litigation, the parties ultimately stipulated that direct infringement occurred. The issue of induced infringement, however, was never presented to the jury.

The Federal Circuit held that although both cases implicated similar facts, including extensive discussions of the “GSS technology,” the direct infringement allegations could not reasonably serve to bar later allegations regarding the actions of third-party licensees. The Court accepted Inguran’s argument that any induced patent infringement claim it might have brought at the time of the earlier case would have been based on speculation: “[w]e agree with ST that it could not have asserted an inducement claim during ABS I.” The Court therefore rejected the district [...]

CEO Punches Ticket and Avoids Sanctions Based on Receiving Confidential Documents

Addressing protective order violations, the US Court of Appeals for the Fifth Circuit largely vacated a district court’s sanctions order. The Court explained that sanctions must comply with due process, barring parties from future litigation should be treated as a “death-penalty” sanction and damages calculations require specific factfinding. CEATS, Inc. v. TicketNetwork, Inc., Case No. 21-40705 (5th Cir. June 19, 2023) (Elrod, Haynes, Willett, JJ.)

To settle a long-running dispute, TicketNetwork licensed several patents from CEATS, a non-practicing patent assertion entity. Several years into the license, all of the licensed patents were invalidated in an unrelated litigation. TicketNetwork promptly stopped paying royalties and filed suit seeking a declaration that the license agreement was unenforceable. CEATS counterclaimed for breach of contract.

During discovery, CEATS requested TicketNetwork’s list of affiliates, which TicketNetwork refused to produce, citing its highly confidential nature. After two discovery hearings, the district court ordered TicketNetwork to produce the affiliate list but specifically prohibited CEATS from using the list for any purpose other than use in the present litigation.

At trial, a jury found that TicketNetwork breached the license, and the district court awarded attorneys’ fees and costs to CEATS. After the jury verdict, CEATS CEO Milford Skane asked his litigation consultants for a “non-confidential” list of TicketNetwork’s affiliates. The consultants gave Skane the confidential list, which was promptly used in settlement negotiations with TicketNetwork. TicketNetwork filed for sanctions, requesting damages from CEATS and an injunction preventing CEATS from suing or seeking licenses from the listed affiliates.

The district court ordered an investigation and, after two years of inquiry and an all-day evidentiary hearing, found that Skane, the consultants and CEATS all violated the protective order and were jointly and severally liable to TicketNetwork. As sanctions, the district court awarded $500,000 in attorneys’ fees (using a billing rate nearly double the one it used when calculating CEATS’s fees) and barred Skane, the consultants and CEATS from suing or seeking licenses from any of TicketNetwork’s affiliates.

The sanctioned parties appealed and argued:

  • The district court violated due process by finding Skane and the consultants personally liable without giving them notice or opportunity to respond.
  • The district court erred by barring the parties without a finding of bad faith.
  • The district court’s damages calculation was unsupported.

The Fifth Circuit began by addressing the sanctions against Skane and the litigation consultants. The Court explained that sanctions require due process, which includes both fair notice and the opportunity to defend against the claim. The Court observed that the first time Skane and the consultants were made aware that they could be sanctioned was in the sanctions order itself—and their only opportunity to defend themselves took place after that order. Given the lack of any advance notice, the Fifth Circuit concluded that due process had not been satisfied and vacated the monetary sanctions against Skane and the consultants.

The Fifth Circuit also vacated the bar preventing Skane, the consultants and CEATS from suing or seeking licenses from any of the affiliates. Core [...]

First Rule of the PTAB? Play by the Rules

The US Court of Appeals for the Federal Circuit affirmed two Patent Trial & Appeal Board decisions holding the challenged claims unpatentable as obvious, even though the Board declined to consider evidence of antedating and found that the claims lacked written description support. Parus Holdings, Inc. v. Google LLC, Case Nos. 22-1269; -1270 (Fed. Cir. June 12, 2023) (Lourie, Bryson, Reyna, JJ.)

Parus Holdings owns two patents related to an interactive voice system to request information from a voice web browser. Google (among others) petitioned for inter partes review (IPR) of the patents.

During the IPR proceedings, the Board found that a publication (Kovatch) was prior art to the challenged patents. In reaching that decision, the Board declined to consider Parus’s arguments and evidence of an earlier conception and reduction to practice because they were only presented via incorporation by reference in violation of 37 C.F.R. § 42.6(a)(3). The Board ruled that Parus failed to meet its burden of production on antedating.

The Board also found that the publication of the application to which Parus’s challenged patents claimed priority (Kurganov-262) was prior art because the common specification failed to provide written description support for the challenged claims. Parus appealed the Board’s decision, raising two main arguments.

First, Parus contended that the Board erred when it declined to consider Parus’s arguments and evidence on antedating. Parus argued that § 42.6(a)(3)’s prohibition on incorporation by reference did not warrant the Board’s decision because Parus, as patent owner, need not have submitted a response at all. Parus also argued that the Federal Circuit’s 2017 decision in Aqua Products mandates that the Board consider all record evidence, regardless of the manner of presentation. The Federal Circuit rejected Parus’s arguments in turn.

Regarding Parus’s violation of the incorporation by reference rule, the Federal Circuit explained that Parus had assumed an affirmative burden of production when it chose to submit a response to antedate Kovatch. Along with that burden came other responsibilities, such as complying with the US Patent & Trademark Office’s (PTO) rules and regulations, including § 42.6(a)(3). The Court further explained that this burden of production could not be met without some combination of citing evidence with specificity and explaining the significance of the cited material. Parus did neither.

The Federal Circuit also rejected Parus’s argument that the Board is required by law to review all evidence in the record. The Court clarified that, while its Aqua Products holding requires the Board to decide all issues properly before it, nothing in Aqua Products requires the Board to review evidence or issues not introduced or introduced in violation of the Board’s rules. As the Court noted, “[t]he burden of production cannot be met simply by throwing mountains of evidence at the Board without explanation or identification of the relevant portions of that evidence. One cannot reasonably expect the Board to sift through hundreds of documents, thousands of pages, to find the relevant facts.”

Parus also argued that the Board exceeded its statutory authority under 35 U.S.C. [...]
