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

by | Jul 29, 2021 |

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 [...]

Arthrex Argument May Be Available in Round Two

by | May 20, 2021 |

The US Court of Appeals for the Federal Circuit found that a party did not waive the Patent Trial & Appeal Board’s (Board) constitutionality argument by raising it for the first time in its opening brief because the Court’s decision in Arthrex, Inc. v. Smith & Nephew, Inc. was issued after the party sought rehearing. New Vision Gaming v. SG Gaming, Inc., Case Nos. 20-1399, -1400 (Fed. Cir. May 13, 2021) (Moore, J.) (Newman, J. concurring in part, dissenting in part)

New Vision appealed two covered-business method (CBM) review final written decisions in which the Board found that all claims of the patents, as well as its proposed substitute claims, were directed to patent ineligible subject matter under 35 U.S.C. § 101. In its opening brief before the Federal Circuit, New Vision requested the Court vacate and remand the Board’s decisions in light of Arthrex. SG Gaming argued New Vision had waived its right to a challenge under Arthrex since it raised it for the first time on an appeal. The Court disagreed, finding that New Vision had not waived its ability to challenge the Board’s decision under Arthrex since Arthrex was issued after the Board’s final written decisions and after New Vision sought Board rehearing. The Court vacated the Board’s final written decisions in the CBMs and remanded for further proceedings consistent with Arthrex without reaching the merits or any other issues.

In her partial dissent, Judge Pauline Newman agreed that Arthrex applied and vacating the Board’s final written decisions was appropriate. She also argued that another threshold issue (venue) should have been resolved, rendering the remand under Arthrex unnecessary and unwarranted. Additionally, Judge Newman agreed with New Vision that since the parties agreed to a different forum for dispute resolution in their license agreement, compliance with the parties’ patent license agreement would be appropriate. Under that agreement, if “any dispute” arose, jurisdiction would be “exclusive” in the appropriate federal or state court in the state of Nevada. New Vision filed suit in the federal district court in Nevada before SG filed CBM petitions before the Board. The Board stated it “[does] not discern, nor has Patent Owner pointed to, any portions of chapter 32 or § 18 of the AIA, or authority otherwise, that explicitly provide for a contractual estoppel defense,” in its decision and proceeded to a final decision despite the forum selection agreement.

Both parties briefed the forum selection question, with New Vision citing the Federal Circuit 2019 decision in Dodocase VR v. MerchSource in which a case was removed from the Board based on an agreed choice of forum. SG countered that the Board’s rejection of choice of forum is an unreviewable “institution” decision under Thryv vs. Click-to-Call. Andrei Iancu, the Director of the US Patent and Trademark Office (USPTO), intervened in the appeal, arguing that the Board’s decision is “final and nonappealable” under 35 U.S.C. § 324(e). As to the Board’s “conduct” in declining to [...]

Prosecution History Prevents Patent Owner from “Intercepting” Win on Appeal

by | May 20, 2021 |

In reviewing whether the Patent Trial & Appeal Board (Board) correctly interpreted the meaning of “intercepting” in the context of Voice over Internet Protocol (VoIP) technology, the US Court of Appeals for the Federal Circuit found that the claim language and prosecution history supported the Board’s decision. The Court thus affirmed the Board’s construction and subsequent finding of obviousness. Uniloc 2017 LLC v. Apple Inc., Case Nos. 20-1403, -1404 (Fed. Cir. May 12, 2021) (Prost, C.J.)

Uniloc owns a patent directed to a system and method for using various VoIP features, such as caller-ID, call waiting, multi-line service, and different levels of service quality known as the “codec specification.” The patent explains that in order to generate revenue for these features, service providers must maintain control over which subscribers have paid for these additional features. To achieve that control, the system employs an enforcement mechanism that sits between the sender of the communication and the intended recipient. The enforcement mechanism ensures that both parties are authorized to use the particular features by intercepting the signaling message, determining whether the client is authorized, and filtering the signaling message based on the authorization. The majority of the claims require authorization related to only one service type. However, one of the claims (claim 18) requires authorization related to at least two service types.

Apple filed a petition for inter partes review (IPR), alleging that all claims of the patent were invalid as obvious over a prior art patent referred to as Kalmanek. Kalmanek discloses signaling messages that are routed through at least one “gate controller,” which can authenticate the identity of the calling party and authorize the services sought. The services include at least caller-ID and enhanced levels of call quality. Kalmanek’s process is accomplished by sending a SETUP message, which the calling party sends to the gate controllers and then to the intended recipient. After receipt, the called party sends a SETUPACK message along a return path to the gate controllers and then to the caller.

During the IPR, Apple asserted that the term “intercepting” a signaling message associated with the call, as recited in all independent claims, should be interpreted to mean “the signaling [message] is received by a network entity located between the endpoints of the call.” Uniloc disagreed and argued that the term should be interpreted as excluding the receipt of a signaling message by the intended recipient of the message. The Board agreed with Apple’s construction and subsequently found that all terms were invalid as obvious with the exception of claim 18. With respect to claim 18, the Board concluded that Apple failed to meet its burden to show that Kalmanek disclosed authorization related to a codec service. Furthermore, the Board opined that even assuming Apple had properly advanced such an argument, it would have lost on the merits.

On appeal, Uniloc challenged the Board’s construction of the “intercepting” term, and Apple cross-appealed the Board’s finding with respect to the non-obviousness of claim 18. The Federal Circuit affirmed [...]

No Second Bite at the Apple: Injury Must Be Imminent and Non-Speculative to Support Standing

by | Apr 15, 2021 |

The US Court of Appeals for the Federal Circuit ruled that a party did not have Article III appellate standing to obtain review of a final ruling of the Patent Trial & Appeal Board because the underlying district court proceedings had been dismissed with prejudice after a settlement and license agreement were reached. Apple Inc. v. Qualcomm Inc., Case Nos. 20-1561; -1642 (Fed. Cir. Apr. 7, 2021) (Moore, J.)

After Qualcomm sued Apple in district court, Apple filed petitions for inter partes review (IPR) of the asserted patent claims. The Board instituted on both petitions but found that Apple did not prove the challenged claims were obvious. Apple appealed the Board’s final written decisions finding non-obviousness.

While the IPR proceedings were pending, the parties settled their litigation worldwide. The settlement included a license to Apple and payment of royalties to Qualcomm. The parties filed a joint motion to dismiss Qualcomm’s district court action with prejudice, which the district court granted.

At the Federal Circuit, Qualcomm argued that Apple waived any argument to establish its appellate standing by failing to address or submit supporting evidence in its opening brief. However, the Federal Circuit exercised its discretion to reach the issue of standing, explaining that the issue of standing was fully briefed, there was no prejudice to Qualcomm, and the question of standing impacted these and other appeals. Qualcomm sought leave to file a sur-reply addressing Apple’s evidence and arguments on standing, and agreed that if its motions to file a sur-reply were granted, it would not suffer any prejudice, and that evaluating the evidence may resolve standing in other pending cases. The Court granted Qualcomm leave to file a sur-reply.

Apple argued that it had appellate standing based on its ongoing payment obligations that conditioned certain rights in the license agreement, the threat that Apple would be sued for infringing the two patents-at-issue after the expiration of the license agreement, and the estoppel effects of 35 USC § 315 on future challenges to the validity of the asserted patents. The Federal Circuit disagreed.

LICENSE RIGHTS

Distinguishing the 2007 Supreme Court case MedImmune v. Genentech (where standing was found based on license agreement payment obligations after analyzing evidence for injury in fact or redressability), the Federal Circuit explained that Apple did not allege that the validity of the patents-at-issue would affect its contract rights and ongoing royalty obligations. The license agreement between the parties involves tens of thousands of patents. Apple did not argue or present evidence that the validity of any single patent (including the two patents-at-issue) would affect its ongoing payment obligations, or identify any related contractual dispute that could be resolved through determining the patents-at-issue’s validity. Accordingly, the Court concluded that Apple failed to establish Art. III standing under MedImmune.

THREAT OF POST-LICENSE SUITS

Apple’s second argument was based on the possibility that Qualcomm might sue Apple for infringing the patents-at-issue after the license expired. The Federal Circuit found the mere possibility of any such suit [...]

PTAB Designates Three Opinions as Precedential

by | Dec 17, 2020 | ,

In RPX Corp. v. Applications in Internet Time, LLC, Case Nos. IPR2015-01750, -01751, -01752 (Oct. 2, 2020) (Boalick, CAPJ) (designated precedential on Dec. 4, 2020), the Patent Trial and Appeal Board (Board) terminated institution of RPX’s petitions for inter partes review (IPR) because Salesforce—served with a complaint more than one year before—should have been named as a real party-in-interest (RPI) to the proceedings. As a result, RPX’s petition was time-barred under § 315(b).

The Board’s determination came after remand from the Federal Circuit, which vacated the Board’s prior finding that Salesforce was not an RPI. (IP Update, Vol. 21, No. 8). The Federal Circuit instructed the Board to use the common law understanding of “real party-in-interest” and a “flexible approach that takes into account both equitable and practical considerations, with an eye toward determining whether the non-party is a clear beneficiary that has a pre-existing, established relationship with the petitioner.” On remand, the Board took additional discovery to examine the relationship between RPX and Salesforce, including RPX’s business model, Salesforce’s relationship with RPX, whether RPX represents Salesforce’s interests in invalidating the patents, and the significance of the fact that Salesforce and RPX had overlapping Board members. After considering the relationship, the Board found the evidence pointed clearly toward a common interest—between RPX and its members—in invalidating the patents in IPR proceedings. It found RPX could not avoid the time bar under § 315(b), or estoppel under § 315(e) for its members, by creating the appearance that RPX acts independently of its members’ interests when filing IPR petitions.

In SharkNinja Operating LLC v. iRobot Corp., Case No. IPR2020-00734 (Oct. 6, 2020) (Melvin, APJ) (designated precedential on Dec. 4, 2020), the Board declined to address—for purposes of institution—the patent owner’s claim that the IPR petition failed to name an alleged RPI under § 312(a)(2)’s requirement that a petition “identif[y] all real parties-in-interest.” iRobot alleged that JS Global was an unnamed RPI because it was intertwined with SharkNinja’s business and was in a position to fund and exercise control over the IPR petition. The Board declined to reach a determination on the issue because it would have no impact on the proceeding, absent evidence that (1) JS Global was a time-barred or an otherwise estopped entity whose addition to the petition would result in its dismissal under § 315 or (2) SharkNinja’s omission of JS Global was done in bad faith. Even if SharkNinja was mistaken in its decision not to name JS Global as an RPI, the Board’s precedent would allow SharkNinja to correct the mistake during the proceeding.

In Apple Inc. v. Uniloc 2017 LLC, Case No. IPR2020-00854 (Oct. 28, 2020) (Quinn, APJ) (designated precedential on Dec. 4, 2020), the Board exercised its discretion to deny Apple’s motion for joinder because it would have resulted in a “serial attack” on Uniloc’s patent. Apple had previously filed an IPR petition on the same patent, alleging various grounds of invalidity. The Board denied institution because it failed to show a reasonable likelihood [...]

Wave Goodbye to Lost Arguments: Waiver Versus Forfeiture Law

by | Nov 24, 2020 | ,

The US Court of Appeals for the Federal Circuit concluded that a patent owner forfeited claim construction arguments on appeal by not presenting them first to the Patent Trial and Appeal Board for consideration. In re: Google Tech. Holdings LLC, Case No. 19-1828 (Fed. Cir. Nov. 13, 2020) (Chen, J.)

Google submitted an application to the US Patent and Trademark Office (PTO) seeking patent claims covering certain means and methods for transferring content to video-on-demand systems. During examination, the examiner rejected Google’s proposed claims based on obviousness in light of certain references. After receiving a final rejection, Google appealed to the Board, relying heavily on block quotes from the references and proposed claims to argue that the examiner improperly found obviousness.

The Board affirmed the examiner’s rejection. Applying the broadest reasonable interpretation standard, the Board construed two claim terms: “costs” and “network impact.” In defining those terms, the Board noted that Google had not, in the course of appealing the examiner’s decision, “cited to a definition of ‘costs’ or ‘network impact’ in the [s]pecification that would preclude the [e]xaminer’s broader reading.” Google appealed.

Google argued that the Board erred in its constructions. The Federal Circuit never reached the merits, however, instead concluding that Google had not properly presented its arguments first to the PTO. The Court described the oft-forgotten difference between waiver (the voluntary and knowing relinquishment of a right) and forfeiture (the failure to make a timely assertion of a particular right). This case, the Court reasoned, was an example of forfeiture, because Google had failed to urge the claim constructions to the PTO in the first instance.

Google contended that the Federal Circuit should nonetheless review the Board’s determination, because the Board actually ruled on the claim constructions and those issues were ripe for decision before the Court. The Court rejected these arguments, largely because Google identified no excuse for failing to raise the issue earlier, and because the Board’s final decision was not unexpected in the course of the proceedings.

Practice Note: Ultimately, the Court’s opinion presents one approach (perhaps not one consistently followed) regarding what an appellant must do in order to maintain its right to review. Appellees seeking to foreclose appellate review should consider whether, regardless of the Board’s ultimate decision, the appellant appropriately pressed the arguments on the error for which it later seeks appellate review.

Federal Circuit Will Not Second-Guess IPR Institution Denials

by | Nov 11, 2020 | ,

In a series of non-precedential orders, the US Court of Appeals for the Federal Circuit reiterated that it lacks jurisdiction to hear appeals on whether the Patent Trial and Appeal Board properly decided to deny inter partes review (IPR) petitions based on parallel district court litigation. Cisco Systems Inc. v. Ramot at Tel Aviv University, Case Nos. 20-2047, -2049 (Fed. Cir. Oct. 30, 2020); Google LLC v. Uniloc 2017 LLC, Case No. 20-2040 (Oct. 30, 2020); In re: Cisco Systems Inc., Case No. 2020-148 (Fed. Cir. Oct. 30, 2020); Apple Inc. v. Maxell, Ltd., Case No. 20-2132, -2211, -2212, -2213, 21-1033 (Fed. Cir. Oct. 30, 2020).

The 2011 Leahy-Smith America Invents Act (AIA) created various mechanisms for challenging the validity of issued patents in post-grant proceedings before the US Patent and Trademark Office PTO) by adding transitional covered business method and post-grant review proceedings to existing ex parte re-examination, and expanding and renaming inter partes re-examination to inter partes review (IPR).

Under 35 USC §§ 311, 312, a petition for IPR must identify all real parties in interest, identify and support the prior art grounds for challenges to the claims, and provide “such other information as the Director may require by regulation.” Under 35 USC § 314 and 37 CFR 42.4(a), the Board institutes a trial on behalf of the PTO Director, and a “determination by the Director whether to institute an inter partes review under this section shall be final and nonappealable.” In deciding whether to institute the trial, the Board considers, at a minimum, whether a petitioner has satisfied the relevant statutory institution standard. Even when a petitioner has satisfied the institution standard, the Director has statutory discretion under 35 USC 314(a) and 324(a) to deny a petition.

In 2016, the Supreme Court of the United States held in Cuozzo Speed Techs. v. Lee that “the agency’s decision to deny a petition is a matter committed to the Patent Office’s discretion,” and that there is “no mandate to institute review.” The Supreme Court also found that the Director is given broad discretion under 35 USC 315(d) and 325(d) to determine the manner in which “multiple proceedings” before the PTO involving the same patent may proceed, “including providing for stay, transfer, consolidation, or termination of any such matter or proceeding.” Subsequent PTO policies and precedential Board decisions set forth factors affecting the case-specific analysis of whether to institute an AIA proceeding, and particularly a follow-on or serial petition, or discretionary denial due to the timing of parallel district court proceedings.

In Cisco v. Ramot, the Board denied Cisco’s petitions to institute IPRs against two patents that Ramot had asserted against it in a district court case. The decisions denying Cisco’s petitions cited the Board’s discretion under 35 USC § 314(a) not to institute review and relied on the factors determining whether efficiency, fairness and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding. Specifically, the Board [...]

PTO Seeks Comments on Proposed Rulemaking for Denying Patent Reviews

by | Oct 29, 2020 | ,

The US Patent and Trademark Office (PTO) requested public comments on considerations for instituting trials under the Leahy-Smith America Invents Act (AIA). Comments are due by November 19, 2020.

Patent practitioners have grown accustomed to reviewing the PTO Patent Trial and Appeal Board (Board) administrative guide, precedential or informative opinions, and other published filings and decisions to discern best practices for filing petitions for and defending against inter partes review, post-grant review, covered business method and derivation proceedings before the Board. For example, the latest Board Consolidated Trial Practice Guide (Nov. 2019) (CTPG) is available here. The PTO is considering codifying or modifying its current policies and practices through formal rulemaking and wishes to gather public comments on its current approach and other approaches suggested by stakeholders.

PTO policies and Board decisions such as General Plastic, Valve Corp. I, Valve Corp. II, NHK Spring and Fintiv set forth factors for analyzing whether to institute an AIA proceeding (and particularly a follow-on or serial petition) or issue a discretionary denial due to the timeline for parallel district court proceedings. Many of these policies and cases are also discussed in the CTPG. The PTO already has received input from stakeholders on these policies that expand on the PTO director’s discretionary authority to institute an AIA trial. Most stakeholder comments suggested that the case-specific analysis outlined in precedential opinions and the CTPG achieves the appropriate balance and reduces gamesmanship—for example, by ensuring that AIA proceedings do not create excessive costs and uncertainty for the patent owner or the system, while allowing meritorious challenges to patents to be heard. However, some stakeholders have proposed that the PTO adopt brightline rules, regardless of the case-specific circumstances, to:

  • Use its discretion to preclude claims from being subject to more than one AIA proceeding
  • Permit more than one AIA proceeding only if the follow-on petitioner is unrelated to the prior petitioner
  • Place no limits on the number of petitions that can be filed or the number of AIA trials that can be instituted against the claims of a patent, so long as the petition complies with statutory timing requirements and the institution threshold of showing that at least one claim of the patent is unpatentable
  • Preclude institution of an AIA trial against challenged claims if the patent owner opposes institution and a related district court or US International Trade Commission (ITC) action (in which any of the challenged claims are or have been asserted against the petitioner, the petitioner’s real-party-in-interest or a privy of the petitioner) is unlikely to be stayed
  • Eliminate any consideration of the status of any district court or ITC actions involving the challenged patent, so long as the petition complies with statutory timing requirements and the institution threshold.

These contrasting views prompted the PTO to issue a request for comments on the factors that should be considered as part of a balanced assessment of the relevant circumstances when exercising its discretion to institute an AIA trial. The PTO [...]

No Due Process Violation When New Panel Hears Substantive Arguments

by | Oct 8, 2020 | ,

Affirming a Patent Trial and Appeal Board (Board) non-obviousness determination, the US Court of Appeals for the Federal Circuit found that the Board did not abuse its discretion in sanctioning a patent owner who engaged in ex parte communications by having a new panel hear the merits of the petition. Apple Inc. v. Voip-Pal.com Inc., Case Nos. 18-1456, -1457 (Fed. Cir. Sept. 25, 2020) (Reyna, J.).

Voip-Pal sued Apple for allegedly infringing two of its patents directed to routing communications between two different types of networks: public and private. Apple then petitioned for inter partes review (IPR) of several claims from both patents, arguing they were invalid as obvious. The Board ultimately found the claims were not invalid because Apple did not provide evidentiary support as to the motivation to combine multiple references.

During the IPR proceedings, Voip-Pal’s former CEO sent six letters to various parties, copying members of Congress, the President, federal judges and administrative patent judges at the Board criticizing the IPR system, complaining about the cancellation rate and requesting judgment in favor of Voip-Pal. The letters did not discuss the underlying merits of Apple’s petitions. In view of Voip-Pal’s conduct, Apple requested that the Board sanction Voip-Pal by entering adverse judgment against Voip-Pal or by vacating the final written decisions and assigning a new panel to preside over “constitutionally correct” new proceedings going forward.

For the sanctions proceeding, a new panel replaced the initial panel and determined that Voip-Pal had engaged in sanctionable conduct, and further determined that it  would preside over Apple’s petition for rehearing. The new panel found that Apple failed to show the initial panel had misapprehended or overlooked any matter, and even if the final panel were to accept Apple’s view of the prior art, it would not reach a different conclusion. Apple appealed.

On appeal, the Federal Circuit first addressed whether the appeal was moot. Before oral argument, the Court found in separate proceedings that some, but not all, of the claims at issue were invalid. Apple argued that this case mooted the entire appeal, even though the claims did not entirely overlap. Starting with the overlapping claims, the Court found that the appeal was moot in regards to these claims because Apple no longer had the potential for injury. However, the Court rejected Apple’s argument that the appeal was moot under a theory of claim preclusion in regards to the non-overlapping claims. The Court explained that any preclusive effect from the other appeal must be decided by a future court in any subsequent action brought by Voip-Pal. Thus, any discussion regarding claim preclusion would be advisory in nature and outside the scope of the Court’s Article III jurisdiction.

Turning to the merits, the Federal Circuit affirmed the Board did not violate the Administrative Procedure Act (APA) or Apple’s due process rights. The Board’s rules provide that “[t]he Board may impose a sanction” and explains that “[s]anctions include entry of one or more” of eight defined actions. Although the Board’s sanctions imposed [...]

No Refunds: Cancellation of Patent Claims in IPR Isn’t a Taking

by | Sep 3, 2020 |

The US Court of Appeals for the Federal Circuit found that cancellation of a patent in an inter partes review (IPR) proceeding is not a taking and does not grant the patentee any compensable claim against the United States. Christy, Inc. v. United States, Case No. 19-1738 (Fed. Cir. Aug. 24, 2020) (Hughes, J.).

After Christy sued two competitors for infringement of a patent directed to a vacuum, one of the competitors filed petitions for IPR. The Patent Trial and Appeal Board (PTAB) instituted the IPRs and ultimately found a majority of the patent claims unpatentable. Christy appealed to the Federal Circuit, which affirmed the PTAB’s invalidity decision.

Christy then filed a class action suit in the US Court of Federal Claims to recover from the government the issuance and maintenance fees Christy had paid for the patent, investments Christy had made in the patented technologies, attorneys’ fees from defending the IPR proceedings, the value of the patent claims, royalties and other payments for use of the patents. The government moved to dismiss all six claims for lack of subject matter jurisdiction and failure to state a claim. The court partially granted the motion to dismiss, but found that it had jurisdiction to consider Christy’s Fifth Amendment takings claim. The court found that Christy did not state a claim for relief on the merits, and reasoned that the cancellation of claims in an IPR did not amount to a compensable taking of Christy’s property interest. The court held that it did not have jurisdiction to consider Christy’s alternative illegal exaction claim, since a statute granting authority to the US Patent and Trademark Office (PTO) to refund mistakenly excessive patent-related fees displaced the court’s Tucker Act jurisdiction. In any case, the court found that on the merits, Christy’s issuance and maintenance fees were properly owed at the time they were paid, and were not paid by mistake. The government did not require Christy to pay any alleged damages on the government’s behalf, or at all, and so Christy’s theory that damages were illegally exacted was found “devoid of merit.” Christy appealed.

On appeal, Christy argued that the claims court erred in finding 1) that Christy failed to state a compensable taking claim based on the cancellation of patent claims, 2) that the claims court lacked subject matter jurisdiction over the illegal exaction claim, and 3) that Christy failed to state a plausible illegal exaction claim. The Federal Circuit disagreed, affirming the claims court and reiterating its finding in Golden v. United States that the AIA did not displace Tucker Act jurisdiction over IPR-based takings claims, and that cancellation of patent claims in an IPR cannot be a taking under the Fifth Amendment. Thus, the Court found that the claims court correctly found that it had jurisdiction over Christy’s takings claim, but that such cancellation was not a taking.

The Federal Circuit next considered Christy’s illegal exaction claim. Illegal exaction occurs when money is “improperly paid, exacted, or taken from the claimant [...]
