2 CHRISTY, INC. v. UNITED STATES
______________________
Before LOURIE, REYNA, and HUGHES, Circuit Judges.
HUGHES, Circuit Judge.
Christy, Inc. asserts that the United States owes it just
compensation for the Patent Trial and Appeal Board’s can-
cellation of claims 1–18 of Christy’s patent, U.S. Patent
No. 7,082,640, in two inter partes reviews. Because the
cancellation of a patent in an inter partes review does not
grant the patentee any compensable claim against the
United States, we affirm the Court of Federal Claims’s dis-
missal of the case for failure to state a claim.
I
Christy applied for a patent on its “ambient air back-
flushed filter vacuum” invention in 2003. The ’640 patent,
which claims that invention, issued in 2006. As required
by law, Christy paid the $1,000 issuance fee. Over the en-
suing years, Christy paid the necessary $490 3.5-year,
$1,800 7.5-year, and $3,700 11.5-year maintenance fees for
the patent—in October 2009, January 2014, and Janu-
ary 2018, respectively.
In 2014, Christy and its licensee, CDC Larue Indus-
tries, Inc., sued two competitors for patent infringement.
See CDC Larue Indus., Inc v. Black & Decker (U.S.) Inc.,
No. 14-CV-0286-CVE-FHM (N.D. Okla.). One of those
competitors then filed two petitions for inter partes review
of the ’640 patent. The Board’s final written decisions
across those inter partes reviews found claims 1–18 un-
patentable; dependent claims 19–20 were not challenged in
the proceedings and remained valid. See Black & Decker
(U.S.) Inc. v. Christy, Inc., No. IPR2015-00468, 2016 WL
3382465 (P.T.A.B. June 17, 2016); Black & Decker (U.S.)
Inc. v. Christy, Inc., No. IPR2015-00472, 2016 WL 3382466
(P.T.A.B. June 17, 2016). We summarily affirmed the
Board’s invalidity decision in IPR2015-00468 and
Case: 19-1738 Document: 66 Page: 3 Filed: 08/24/2020
CHRISTY, INC. v. UNITED STATES 3
dismissed Christy’s appeal of the Board’s decision in
IPR2015-00472 as moot. See Christy, Inc. v. Black &
Decker (U.S.), Inc., No. 2016-2499, 696 F. App’x 1020 (Fed.
Cir. Sept. 7, 2017) (mem.) (per curiam); Christy, Inc. v.
Black & Decker (U.S.), Inc., No. 2016-2498, 696 F. App’x
1020 (Fed. Cir. Sept. 7, 2017) (mem.) (per curiam).
Aggrieved by the cancellation of its first 18 claims of
the ’640 patent, Christy filed a class-action suit in the
Court of Federal Claims. The suit raised six claims for
compensation from the government: a Fifth Amendment
takings claim, four claims based on contractual theories,
and an illegal exaction claim raised in the alternative to
the takings claim. Christy sought compensation amount-
ing to the ’640 patent’s “issuance and maintenance fees,
[Christy’s] investments made in the patented technologies,
the attorney fees [Christy] spent in defending the [inter
partes review proceedings] that invalidated the claims, and
the value of the patent claims themselves . . . includ[ing]
expected royalties and other payments related to use of the
patents[], in an amount to be determined at trial.” J.A. 72–
73 ¶ 107 (emphasis removed).
The government swiftly moved to dismiss all claims for
both lack of subject matter jurisdiction and failure to state
a claim. The court granted the government’s motion, with
various grounds for dismissing each count. 1 See generally
Christy, Inc. v. United States, 141 Fed. Cl. 641 (2019) (De-
cision). Over the government’s challenge, the court found
that it had jurisdiction to consider the takings claim. De-
cision at 657. Yet the court found that Christy did not state
a claim for relief on the merits. Id. at 660. The court rea-
soned that the cancellation of patent claims in an inter
1 The court found the contract-based claims non-
meritorious; Christy does not argue that the court erred in
that decision, so we address it no further.

4 CHRISTY, INC. v. UNITED STATES
partes review did not amount to a compensable taking of
Christy’s property interest. Id.
In contrast, the court held that it did not have jurisdic-
tion to consider the illegal exaction claim. Decision at 668.
It held that a statute granting authority to the U.S. Patent
and Trademark Office to refund mistakenly excessive pa-
tent-related fees displaced Tucker Act jurisdiction over
those fees. Id. at 667–68; see 35 U.S.C. § 42(d). The court
addressed the merits of the illegal exaction claim in the al-
ternative, however, finding that Christy’s issuance and
maintenance fees paid for the ’640 patent “were owed at
the time they were paid, and as such, were not fees paid by
mistake.” Decision at 668 (quoting In re Patent
No. 7,061,177, 2006 WL 4559506, at *1 (Comm’r Pat.
Oct. 17, 2006)). Because “the government did not require
Christy to pay” any of the other alleged damages “to a third
party on the government’s behalf, or even to be paid at all,”
the court found Christy’s theory that these damages were
illegally exacted “devoid of merit.” Decision at 669.
Christy timely appealed; we have jurisdiction under
28 U.S.C. §1295(a)(3).
We review whether Tucker Act jurisdiction exists
“without deference to the decision of the trial court.” In re
United States, 463 F.3d 1328, 1334 (Fed. Cir. 2006). We
similarly review de novo the trial court’s dismissal of tak-
ings claims and illegal exaction claims for failure to state a
claim. See, e.g., Piszel v. United States, 833 F.3d 1366, 1373
(Fed. Cir. 2016).
II
Christy argues that the Court of Federal Claims erred
in three ways: by (1) finding that Christy failed to state a
compensable takings claim based on the cancellation of
claims 1–18 of the ’640 patent; (2) finding that the court
lacked subject matter jurisdiction over Christy’s illegal ex-
action claim; and (3) finding that Christy failed to state a
Case: 19-1738 Document: 66 Page: 5 Filed: 08/24/2020
CHRISTY, INC. v. UNITED STATES 5
plausible illegal exaction claim. The government concedes
that the Court of Federal Claims erred in finding that it
lacked subject matter jurisdiction over Christy’s illegal ex-
action claim but argues for the first time on appeal that the
court lacked jurisdiction over Christy’s takings claim.
Shortly after this case’s oral argument, we issued
Golden v. United States, 955 F.3d 981 (Fed. Cir. 2020),
which straightforwardly resolves two of the three issues
raised here.
First, Golden disposes of the government’s argument
that the Court of Federal Claims lacked jurisdiction over
Christy’s takings claim. Golden rejected the government’s
indistinguishable argument that the Court of Federal
Claims lacks jurisdiction over a takings claim arising from
the cancellation of patent claims in an inter partes review.
See 955 F.3d at 989 (“[W]e reject the government’s argu-
ment that the [America Invents Act, which enacted the in-
ter partes review process] displaced Tucker Act jurisdiction
over Golden’s IPR-based takings claims.”). As the govern-
ment concedes in its Fed. R. App. P. 28(j) letter discussing
Golden, that decision forecloses the government’s jurisdic-
tional argument here. Appellee’s Citation of Suppl. Auth.,
Christy, Inc. v. United States, No. 2019-1738 (Fed. Cir.
Apr. 17, 2020), ECF No. 62. As a result, the Court of Fed-
eral Claims correctly held that it had subject matter juris-
diction over Christy’s takings claim.
Second, Golden also confirms that Christy failed to
state a plausible claim for a taking based on the cancella-
tion of the ’640 patent. Golden held that “cancellation of
patent claims in [an] inter partes review cannot be a taking
under the Fifth Amendment.” Golden, 955 F.3d at 989 n.7.
The Court of Federal Claims therefore correctly held that
Case: 19-1738 Document: 66 Page: 6 Filed: 08/24/2020
6 CHRISTY, INC. v. UNITED STATES
the cancellation of Christy’s patent claims in an inter
partes review was not a Fifth Amendment taking. 2
Since the government has conceded that the Court of
Federal Claims properly exercised jurisdiction over
Christy’s illegal exaction claim, we last address whether
the court erred in finding that Christy failed to state a
plausible claim of an illegal exaction. An illegal exaction
occurs when money is “improperly paid, exacted, or taken
from the claimant in contravention of the Constitution, a
statute, or a regulation.” Norman v. United States,
429 F.3d 1081, 1095 (Fed. Cir. 2005) (quoting Eastport S.S.
Corp. v. United States, 372 F.2d 1002, 1007 (Ct. Cl. 1967)
(en banc)). Given that the Board did not violate Christy’s
Fifth Amendment rights by canceling its patent claims,
Christy asserts no constitutional provision, statute, or reg-
ulation that the PTO violated by failing to refund Christy’s
issuance and maintenance fee payments for the ’640 pa-
tent. Instead, Christy is left to contend that the PTO’s re-
quiring Christy to pay issuance and maintenance fees for
the ’640 patent was in error, and therefore the fees should
be refunded. See Appellant’s Reply Br. 12–15. According
2 Because Golden indisputably and indistinguisha-
bly binds our conclusion that the cancellation of patent
claims in an inter partes review does not engender a tak-
ing, we need not address Christy’s argument that Celgene
Corp. v. Peter, 931 F.3d 1342 (Fed. Cir. 2019), cert. denied,
No. 19-1074, 2020 WL 3405867 (U.S. June 22, 2020), does
not control this case. Christy perplexingly relies on Golden
to suggest that Celgene does not bind our decision “because
the [t]akings issue was not properly before the Celgene
Court in the first place.” Appellant’s Resp. to Appellee’s
Citation of Suppl. Auth. at 1, Christy, Inc. v. United States,
No. 2019-1738 (Fed. Cir. Apr. 21, 2020), ECF No. 63. But
Golden itself held that Celgene controlled its outcome.
Golden, 955 F.3d at 989.

CHRISTY, INC. v. UNITED STATES 7
to Christy, the cancellation of patent claims in an inter
partes review amounts to an admission that the PTO erred
in allowing the issuance of the claims. See id. at 13–14 (cit-
ing Celgene, 931 F.3d at 1361). Christy maintains that this
supposed error was the “the sole and direct cause of Christy
paying [these] fees,” id. at 14, and that allowing the gov-
ernment to “charge fees for . . . making errors” is “unjust.”
Id. at 15.
Christy’s argument fails because the law requires pay-
ment of these issuance and maintenance fees without re-
gard to any later result of post-issuance proceedings, see,
e.g., 35 U.S.C. §§ 41, 151. Christy identifies no statute, reg-
ulation, or constitutional provision compelling the fees’ re-
fund if claims are later canceled in post-issuance
proceedings. Without showing how the PTO’s actions “con-
travene[ed] . . . the Constitution, a statute, or a regula-
tion,” Christy cannot state a claim for an illegal exaction.
Norman, 429 F.3d at 1095. That Christy finds the legal
scheme dictating patent issuance and maintenance fees
“unjust” raises a policy question properly addressed to Con-
gress or the PTO, for Congress has the authority to set the
terms of the patent right, see U.S. Const. art. I, § 8, cl. 8, 3
and to delegate that authority to the PTO in appropriate
circumstances, see, e.g., Aqua Prods., Inc. v. Matal,
872 F.3d 1290, 1330 (Fed. Cir. 2017) (en banc) (“There are
dozens of very specific grants of rulemaking authority by
3 See Oil States Energy Servs., LLC v. Greene’s En-
ergy Grp., LLC, 138 S. Ct. 1365, 1375 (2018) (citing
Wheaton v. Peters, 33 U.S. 591, 663–64 (1834), which holds
that “[n]o one can deny that when the legislature are about
to vest an exclusive right in an author or an inventor, they
have the power to prescribe the conditions on which such
right shall be enjoyed; and that no one can avail himself of
such right who does not substantially comply with the req-
uisitions of the law”).

Congress to the [PTO].”). Christy’s payment of standard
issuance and maintenance fees—and the PTO’s refusal to
refund the fees after 18 of Christy’s 20 claims in the
’640 patent were canceled—did not stem from any mistake
or impropriety by the PTO, but followed the requirements
of the law. The PTO did not collect fees in excess of its
statutory authority, and therefore did not illegally exact
those fees. We affirm the Court of Federal Claims’s dismis-
sal of Christy’s illegal exaction claim.
III
We have considered the parties’ remaining arguments
and find them unpersuasive. Because Christy did not state
a plausible claim that the cancellation of its patent claims
caused a taking or an illegal exaction, we affirm the judg-
ment of the Court of Federal Claims dismissing its case.
AFFIRMED
