final decision of the U.S. District Court for the Eastern District of Missouri, which entered summary judgment

that the asserted claims of U.S. Patents 5,926,792 and 7,249,037 (the “’792 patent” and “’037 patent”) are invalid under 35 U.S.C. § 101. See Bancorp Servs., L.L.C. v. Sun Life Assurance Co. , No. 4:00-cv-1073 (E.D. Mo. May 25, 2011) (Final Judgment), ECF No. 411. We affirm

B ACKGROUND

Bancorp owns the ’792 and ’037 patents, both entitled“System for Managing a Stable Value Protected Investment Plan.” The patents share a specification and the priority date of September 1996. The ’792 patent has been the subject of two prior appeals to this court. See Metro. Life Ins. Co. v. Bancorp Servs., L.L.C. , 527 F.3d 1330 (Fed. Cir. 2008) (vacating summary judgment of noninfringement); Bancorp Servs., L.L.C. v. Hartford Life
Ins. Co. , 359 F.3d 1367 (Fed. Cir. 2004) (reversing summary judgment of invalidity for indefiniteness).

As explained in our earlier opinions and in the district court’s opinion now on appeal in this case, the patents’specification discloses systems and methods for administering and tracking the value of life insurance policies in separate accounts. Separate account policies are issued pursuant to Corporate Owned Life Insurance (“COLI”)BANCORP SERVICES v. SUN LIFE 3

and Bank Owned Life Insurance (“BOLI”) plans. Under separate account COLI and BOLI plans the policy owner pays an additional premium beyond that required to fund the death benefit, and specifies the types of assets inwhich the additional value is invested. Banks and corporations use the policies to insure the lives of their employees and as a means of funding their employees’ postretirement benefits on a tax-advantaged basis. See Hartford , 359 F.3d at 1369.

The value of a separate account policy fluctuates with the market value of the underlying investment assets. That poses a problem from an accounting standpoint, as BOLI and COLI plan owners must ordinarily report, on a quarter-to-quarter basis, the value of any policies they

own. Id. The volatility inherent in short-term market

values has made some banks and companies reluctant to purchase these plans. Bancorp Servs., L.L.C. v. Sun Life
Assurance Co. , 771 F. Supp. 2d 1054, 1056 (E.D. Mo. 2011). Stable value protected investments address that problem by providing a mechanism for stabilizing the reported value of the policies, wherein a third-party guarantor (the “stable value protected writer”) guarantees a particular value (the “book value”) of the life insurance policy regardless of its market va lue. To offset the risk to a potential guarantor for providing that service, the guarantor is paid a fee and restrictions are placed on the policyholder’s right to cash in on the policy. Hartford , 359 F.3d at 1369. As we previously explained, the asserted patents “provide[] a computeri zed means for tracking thebook value and market value of the policies and calculating the credits representing the amount the stable value protected writer must guarantee and pay should the policy be paid out prematurely.” Id.

The asserted patents disclose specific formulae for determining the values required to manage a stable valueBANCORP SERVICES v. SUN LIFE 4

protected life insurance policy. For example, the specification discloses creating and initializing a fund by performing particular “calculations and comparisons” to determine an “initial unit value of the policy.” ’037 patent col.12 ll.56–58; see also id. col.11 l.67–col.12 l.57, fig. 11. The specification then discloses “processing [that] is required at regular intervals to track existing funds.” Id. col.12 ll.60–61; see also id. col.12 l.59–col.15 l.10, figs. 12– 16. Such processing includes the calculation of “fees” for the individuals who manage the life insurance policy. Id. col.12 l.65–col.13 l.15. That processing also includes the computation of values used for determining “surrendervalue protection investment credits,” which, as we previously explained, “means the difference between the actual value of a protected investment and the targeted return value of that investment at the time the protected life insurance policy is surrendered.” Hartford , 359 F.3d at1372. Those computations include the concept of a “targeted return,” calculated as follows:

The Stable Value Protected funds provide an initial targeted return for the first period of an investment. Upon completion of the first period, the value of the fund, the “market value,” is compared
with the “calculated” value of the fund which is
the “book value.” The “calculated” value of the fund is calculated by multiplying the initial value of the fund by (1+targeted return), wherein the targeted return for the next period is calculated using the formula:

TR=[(MV/BV) (1/D) ×(1+YTM)]-1,

where [TR] is the targeted return, MV is the market value of a fund, BV is the book value of a fund,
D is the duration of a fund and YTM is the current yield to market. . . .BANCORP SERVICES v. SUN LIFE 5

’037 patent col.3 ll.18–30; see also id. col.13 ll.44–53 (disclosing formulae for calculating a “policy value for the present day” and a “policy unit value for the present day”). Those computations also include the “duration of afund,” which is calculated according to a formula wellknown in the prior art. Id. col.3 l.28–col.4 l.5. As the specification explains, “[u]sing the concepts of durationand targeted return, the actual performance of the underlying securities in the fund is smoothed over time.” Id.
col.4 ll.6–8.

At issue on appeal from the ’792 patent are asserted claims 9, 17, 18, 28, and 37. The asserted claims include methods and computer-readable media. Claims 9 and 28 are independent method claims. Claims 9 reads:

9. A method for managing a life insurance policyon behalf of a policy holder, the method comprising the steps of:generating a life insurance policy including a stable value protected investment with an initial value based on a value of underlying securities; calculating fee units for members of a management group which manage the life insurance policy;calculating surrender value protected investment credits for the life insurance policy; determining an investment value and a value of the underlying securities for the current day; calculating a policy value and a policy unit value for the current day;storing the policy unit value for the current day; and one of the steps of:BANCORP SERVICES v. SUN LIFE 6

removing the fee units for members of the management group which manage the life insurance policy, and accumulating fee units on behalf of the
management group.

’792 patent col.16 l.55–col.17 l.8. Independent claim 28 claims “A method for managing a life insurance policy” comprising steps that are not materially different from the steps of claim 9. Id. col.19 ll.10–22. Claims 17 and 37 depend from independent claims 9 and 28, respectively, and require that the methods steps “are performed by a computer.” Id. col.17 ll.60–61; id. col.20 ll.32–33. Claim 18, the computer-readable medium claim, reads: “A computer readable medi[um] for controlling a computer to perform the steps” set out in method claim 9. Id. col.17

l.63–col.18 l.15.

Before us on appeal from the ’037 patent are asserted claims 1, 8, 9, 17–21, 27, 28, 37, 42, 49, 52, 60, 63, 66–68, 72–77, 81–83, 87, 88, and 91–95. Independent claims 9, 28, and 52 claim a “method for managing a life insurance policy” that is not materially different from the methods claimed in the ’792 patent. For example, claim 9 reads:

9. A method for managing a life insurance policy comprising:generating a life insurance policy including a stable value protected investment with an initial value based on a value of underlying securities of the stable value protected investment;calculating fees for members of a management group which manage the life insurance policy;BANCORP SERVICES v. SUN LIFE 7

calculating credits for the stable valueprotected investment of the life insurance policy; determining an investment value and a value of the underlying securities of the stable value protected investment for the current day; calculating a policy value and a policy unit value for the current day;storing the policy unit value for the current day; and removing a value of the fees for membersof the management group which manage the life insurance policy.

’037 patent col.16 ll.31–50. Each independent method claim is further limited in a dependent claim requiring that the method be “performed by a computer.” Id. claims 17, 37, 60. Independent claims 18 and 63 are directed to a “computer readable medi[um] for controlling a computer to perform the steps” set out in the method claims. Claim 18, for example, recites the same seven steps set forth in method claim 9, above.

Independent claims 1, 19, and 42 of the ’037 patentare system claims, which track the content of the aforementioned method and medium claims. For example,
claim 1 reads:

1. A life insurance policy management system comprising:a policy generator for generating a life insurance policy including a stable value protected investment with an initial value based on a value of underlying securities of the stable value protected investment;BANCORP SERVICES v. SUN LIFE 8

a fee calculator for calculating fees for members of a management groupwhich manage the life insurance policy; a credit calculator for calculating creditsfor the stable value protected investment of the life insurance policy; an investment calculator for determining
an investment value and a value of the underlying securities of the stable value protected investment for the current day; a policy calculator for calculating a policy value and a policy unit value for the current day; digital storage for storing the policy unit value for the current day; and a debitor for removing a value of the fees for members of the managementgroup which manages the life insurance policy.

Id. col.15 ll.28–48.

In 2000, Bancorp sued Sun Life Assurance Company of Canada (U.S.) (“Sun Life”) for infringement of the ’792 patent. In 2002, in a separate patent infringement suit filed by Bancorp, the district court invalidated all claims of the ’792 patent for indefiniteness. See Bancorp Servs., L.L.C. v. Hartford Life Ins. Co. , No. 4:00-CV-70, 2002 WL 32727071 (E.D. Mo. Feb. 13, 2002). Bancorp and Sun Lifethen jointly stipulated to dismiss their case due to collateral estoppel arising from the district court’s invalidity ruling in Hartford . The parties further agreed that if the
district court’s Hartford ruling was reversed on appeal

then their case would be reinstated. The district court entered a judgment of conditional dismissal.BANCORP SERVICES v. SUN LIFE 9

In 2004, we reversed the district court’s Hartford ruling. Hartford , 359 F.3d 1367. The district court subsequently vacated its judgment of dismissal in the present

case. Bancorp Servs., L.L.C. v. Sun Life Assurance Co.

, No. 4:00-CV-1073 (E.D. Mo. July 22, 2004), ECF No. 77. In 2009 Bancorp filed an amended complaint adding a claim for infringement of the ’037 patent. The parties then submitted a joint claim construction and prehearing statement addressing numerous disputed claim terms in the ’792 and ’037 patents. Before the court construed theclaims, Sun Life moved for summary judgment of invalidity under § 101 for failure to claim patent-eligible subjectmatter. The court stayed the briefing on Sun Life’s motion pending the Supreme Court’s decision in Bilski v. Kappos , 130 S. Ct. 3218 (2010). After Bilski was decided,briefing on Sun Life’s summary judgment motion commenced.

In a memorandum and order dated February 14, 2011, the district court granted Sun Life’s motion for summary judgment of invalidity under § 101. Bancorp

, 771 F. Supp. 2d at 1067. The court first noted its decision to determine invalidity under § 101 without addressing the parties’ claim construction dispute. Id. at 1059. Thecourt then concluded that there was no meaningful distinction between the asserted “process,” “system,” and “media” claims, and that each would be analyzed as a process claim. Id. ; see also id. at 1065. Next, after reviewing Bilski and other opinions, the court concluded that
“the machine-or-transformation test remains a useful tool in determining whether a clai m is drawn to an abstract idea and thus unpatentable under § 101.” Id. at 1061.

Applying that test, the court evaluated the particular
limitations of the asserted claims and found them deficient. On the machine prong, the court noted that the specified computer components are no more than objectsBANCORP SERVICES v. SUN LIFE 10

on which the claimed methods operate, and that the central processor is nothing more than a general purpose computer programmed in an unspecified manner. Id. at 1064. Additionally, the court noted that “although itwould be inefficient to do so, the steps for tracking, reconciling and administering a life insurance policy with a stable value component can be completed manually.” Id.at 1065. On the transformation prong, the court determined that the claims do not effect a transformation, as they “do not transform the raw data into anything otherthan more data and are not representations of any physically existing objects.” Id. at 1066. Finally, the court analogized the asserted claims to those that the Supreme Court found unpatentable in Bilski

, Gottschalk v. Benson

, 409 U.S. 63 (1972), and Parker v. Flook , 437 U.S. 584 (1978), and concluded that the claims were invalid under § 101 as directed to patent-ineligible abstract ideas. Bancorp , 771 F. Supp. 2d at 1066–67.

After considering and denying Bancorp’s motion for reconsideration, Bancorp Servs., L.L.C. v. Sun Life Assurance Co. , No. 4:00-CV-1073 (E.D. Mo. Apr. 27, 2011), ECF No. 408, the court entered final judgment in favor of Sun Life. Bancorp timely appealed. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1).

D ISCUSSION

Summary judgment is appropriate where “there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). We review a district court’s grant of summaryjudgment without deference, reapplying the same standard as the district court and drawing all reasonable
inferences in favor of the nonmovant. Tokai Corp. v. Easton Enters., Inc. , 632 F.3d 1358, 1366 (F ed. Cir. 2011). We review questions about patent-eligible subject matterBANCORP SERVICES v. SUN LIFE 11

under 35 U.S.C. § 101 without deference. Research Corp. Techs., Inc. v. Microsoft Corp. , 627 F.3d 859, 867 (Fed. Cir. 2010).

I.

A preliminary question in this appeal involves the matter of claim construction. As noted above, the district court declined to construe numerous disputed terms prior to considering invalidity under § 101. The court stated that “[t]here is no requirement that claims construction be completed before examining patentability.” Bancorp

, 771 F. Supp. 2d at 1059. Afte r the district court’s decision, we decided Ultramercial, LLC v. Hulu, LLC , in which we stated that “[t]his court has never set forth a bright line rule requiring district courts to construe claims before determining subject matter eligibility.” 657 F.3d 1323, 1325 (Fed. Cir. 2011), vacated sub nom. WildTangent, Inc. v. Ultramercial, LLC , No. 11-962, 2012 WL 369157 (U.S. May 21, 2012). For support, we cited Bilski

, noting that the Supreme Court “f[ound] subject matterineligible for patent protection without claim construction.” Id. Although Ultramercial has since been vacated by the Supreme Court, we perceive no flaw in the notion that claim construction is not an inviolable prerequisite to a validity determination under § 101. We note, however, that it will ordinarily be desirable—and often necessary— to resolve claim construction disputes prior to a § 101analysis, for the determination of patent eligibility requires a full understanding of the basic character of the claimed subject matter.

Bancorp argues that we must either (1) vacate and remand the district court’s judgment with instructions to construe the claims in the first instance; or (2) adopt Bancorp’s proposed constructions of the disputed claim terms, because, as the nonmovant on summary judgment,BANCORP SERVICES v. SUN LIFE 12

it is entitled to all reasonable inferences in its favor. Bancorp argues that under its construction each claimed “system” requires “one or more computers,” and thus those claims cannot constitute abstract ideas. Bancorp,while acknowledging that the specific hardware components recited in the system claims are not present in the method claims, asserts that a computer is necessary as a practical matter to perform the claimed processes onaccount of the “complex and dynamic nature of the invention,” and that the computer amounts to more than insignificant extra-solution activity. Bancorp Br. 52.

Sun Life responds by arguing that even if we adopt Bancorp’s proposed constructions, the claims are not patent eligible. Sun Life Br. 38 (“Bancorp argues that theCourt should apply its constructions. That is fine.” (citation omitted)). According to Sun Life, assuming the claims require a computer, that limitation merely amounts to insignificant post-solution activity incapable of rendering the claimed subject matter patent eligible. Sun Life thus contends that the district court correctlydetermined that the asserted claims relate to patentineligible abstract ideas.

Numerous claim terms were disputed by the parties at the district court. For purposes of the § 101 issue on appeal, however, the parties’ disagreement boils down to whether the claimed systems and methods require acomputer. Although the district court declined to construe the claims, that does not preclude us from making that legal determination on appeal. See Cybor Corp. v. FAS Techs., Inc. , 138 F.3d 1448, 1455 (Fed. Cir. 1998) (en banc) (concluding that claim construction is a pure issue of law). Just as a district court may construe the claims in a way that neither party advocates, Exxon Chemical Patents, Inc. v. Lubrizol Corp. , 64 F.3d 1553, 1555 (Fed. Cir. 1995) (“[T]he trial judge has an independent obliga-BANCORP SERVICES v. SUN LIFE 13

tion to determine the meaning of the claims, notwithstanding the views asserted by the adversary parties.”), we may depart from the district court and adopt a new construction on appeal, Praxair, Inc. v. ATMI, Inc. , 543 F.3d 1306, 1323–24 (Fed. Cir. 2008) (adopting “a new claim construction on appeal,” and noting that “the court has an independent obligation to construe the terms of a patent [and] need not accept the constructions proposed by either party”).

Before proceeding to our § 101 analysis, we construe
the claims as follows. We conclude that the assertedsystem claims require “one or more computers,” as Bancorp asserts and as Sun Life appears to concede. The plain language of the system claims requires particular computing devices, such as a “generator,” a “calculator,” and “digital storage.” The specification supports our construction, explaining that Figure 1, which shows “an embodiment of the system of the present invention,” depicts a “computer” and “a central processing unit for a memory subsystem.” ’037 pa tent col.6 ll.44–47.

Regarding the computer-readable medium claims, the specification explains that that term refers generally to a “high density removable storage means,” id. col.7 ll.66–67, such as a “compact disc,” id. col.6 ll.50–51, col.7 l.62. Neither party appears to argue that “computer readable media” should not carry this plain and ordinary meaning.

As for the method claims, the parties dispute whetherthe steps require a computer to be performed. In resolving that issue, we must distinguish between the independent and dependent claims. The plain language of the independent method claims does not require a computer. As noted above, however, each asserted independent method claim is further followed by a dependent claim requiring that the method be “performed by a computer.”BANCORP SERVICES v. SUN LIFE 14

The doctrine of claim differentiation, while not a hard and fast rule of construction, creates a presumption that the independent method claims do not contain this limitation,for “the presence of a dependent claim that adds a particular limitation raises a presumption that the limitation in question is not found in the independent claim.” Liebel-Flarsheim Co. v. Medrad, Inc. , 358 F.3d 898, 910 (Fed. Cir. 2004) (“[W]here the limitation that is sought to be ‘read into’ an independent claim already appears in a dependent claim, the doctrine of claim differentiation is at its strongest.”).

We conclude that the asserted independent method claims do not require implementation on a computer. Theplain language of those claims does not require a computer, and the doctrine of claim differentiation creates a presumption that the independent claims, unlike thedependent claims, do not require a computer to be implemented. Bancorp fails to rebut that presumption with its unpersuasive assertion that a computer is “inherent” in the independent method claims. Bancorp Br. 52. As the district court observed, “although it would be inefficient todo so, the steps for tracking, reconciling and administering a life insurance policy with a stable value component can be completed manually.” Bancorp , 771 F. Supp. 2d at 1065. Unlike the independent claims, however, the dependent method claims are plainly limited to being “performed by a computer.”

II.

We turn now to the issue of patent eligibility. Section 101 of the Patent Act defines patentable subject matter, stating that “[w]hoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefore, subject to the conditions andBANCORP SERVICES v. SUN LIFE 15

requirements of this title.” 35 U.S.C. § 101; see also 35 U.S.C. § 100(b) (“The term ‘p rocess’ means process, art or method, and includes a new use of a known process, machine, manufacture, composi tion of matter, or material.”). From those broad categories, the Supreme Courthas carved out three exceptions of subject matter ineligible for patent protection: “laws of nature, physical phenomena, and abstract ideas.” Diamond v. Chakrabarty

, 447 U.S. 303, 309 (1980); see also Mayo Collaborative Servs. v. Prometheus Labs., Inc. , 132 S. Ct. 1289, 1293 (2012). As the Court has explained, “[p]henomena of nature, though just discovered, mental processes, and abstract intellectual concepts are not patentable, as they
are the basic tools of scientif ic and technological work.”

Benson , 409 U.S. at 67. “[A] process is not unpatentablesimply because it contains a law of nature or a mathematical algorithm,” and “an application of a law of nature
or mathematical formula to a known structure or process may well be deserving of patent protection.” Diamond v.
Diehr , 450 U.S. 175, 187 (1981) (internal quotation marks omitted). However, “limiting an abstract idea to one field of use or adding token postsolution components d[oes] not make the concept patentable.” Bilski , 130 S. Ct. at 3231. In other words, a recitation of ineligible subject matter does not become patent-eligible merely by adding the words “apply it.” See Mayo , 132 S. Ct. at 1294.

Bancorp argues that its system and medium claims cover tangible machines and manufactures and therefore cannot be considered patent-ineligible abstract ideas under § 101. According to Bancorp, the district court ignored the computer and hardware limitations in those claims when performing it s § 101 analysis. Bancorp further contends that its “method” claims are patent eligible under our opinions in Research Corp. and Ultramercial (the latter of which the Supreme Court vacatedBANCORP SERVICES v. SUN LIFE 16

after Bancorp filed its briefs). Bancorp contends that itsprocess claims have specific applications to the marketplace and require complex computer programming. Bancorp also contends that the district court placed improper weight on the machine-or-transformation test, which, according to Bancorp, its process claims nonetheless satisfy.

Sun Life, in response, argues that Bancorp’s asserted process claims are unpatentable under Bilski and the Supreme Court’s other § 101 opinions. Sun Life assertsthat the process claims fail the machine-ortransformation test because the claim steps do not requirea computer to be performed. Even if those claims required a computer, Sun Life contends, the claims are unpatentable, because the routine use of a computer to perform calculations cannot turn an otherwise ineligible mathematical formula or law of nature into patentable subject matter. Finally, Sun Life argues that the system and medium claims merely paraphrase the unpatentable method claims, and as a result they are not patent eligible
for the same reasons as the method claims.

A.

We first address Bancorp’s assertion that the district court legally erred by extending the Supreme Court’s prohibition against patenting abstract ideas to Bancorp’s system and medium claims. In its § 101 analysis, the district court perceived no difference between the claimed methods, on the one hand, and the claimed systems and media, on the other. Rather, the court noted that the “specified machines appear to be no more than ‘object[s] on which the method operates.’” Bancorp , 771 F. Supp. 2d at 1064 (alteration in original) (quoting Graff/Ross Holdings LLP v. Fed. Home Loan Mortg. Corp. , No. 07-796, 2010 WL 6274263, at *5 (D.D.C. Aug. 27, 2010)). Previ-BANCORP SERVICES v. SUN LIFE 17

ously sitting en banc , we declined in In re Alappat todecide whether a claimed apparatus could be unpatentably abstract under § 101. Referring to the abstract-idea exception as the “mathematical” exception, we stated:

“ Even if the mathematical subject matter exception to § 101 does apply to true appa ratus claims, the claimed subject matter in this case d oes not fall within that exception.” 33 F.3d 1526, 1542 (Fed. Cir. 1994) (en banc) (emphasis added). Subsequent ly, however, we explained

in CyberSource Corp. v. Retail Decisions, Inc. that we look not just to the type of claim but also “to the underlying invention for patent-eligibility purposes.” 654 F.3d 1366,1374 (Fed. Cir. 2011). We applied that principle in concluding that a claim directed to a “computer readablemedium,” despite its format, should be treated no differently from the comparable process claims held to be patent ineligible under § 101. Id. at 1375. Most recently,

in CLS Bank International v. Alice Corp. , we held that the format of the various method, system, and media claimsasserted in that case “d[id] not change the patent eligibility analysis under § 101. ” No. 2011-1301, 2012 WL 2708400, at *10 (Fed. Cir. July 9, 2012).

Thus, under Cybersource and CLS , a machine, system, medium, or the like may in some cases be equivalent to an abstract mental process for purposes of patent ineligibility. As the Supreme Court has explained, theform of the claims should not trump basic issues of patentability. See Flook , 437 U.S. at 593 (advising against a rigid reading of § 101 that “would make the determination of patentable subject matter depend simply on the draftsman’s art”); see also Mayo , 132 S. Ct. at 1294.

On the facts of this case, we hold that the district court correctly treated the asserted system and medium
claims as no different from the asserted method claims for patent eligibility purposes. For example, in the ’037BANCORP SERVICES v. SUN LIFE 18

patent, method claim 9 recites a “method for managing a life insurance policy comprising” seven steps, whereas medium claim 18 recites “a computer readable media [sic] for controlling a computer to perform” the same seven steps of method claim 9, repeated word for word. Compare ’037 patent col.16 ll.31–48, with id. col.17 ll.33–50.There is no material difference between these two categories of claims in the asserted patents.

The equivalence of the asserted method and system claims is also readily appare nt. By way of example, we compare method claim 9 and system claim 1 of the ’037
patent. Id. col.15 ll.28–48, col.16 ll.31–48. Claim 9 claims a “method for managing a life insurance policy,” whereas claim 1 of that patent claims “a life insurance policymanagement system.” Claim 9 includes the step of “generating a life insurance policy,” whereas claim 1 includes “a policy generator for generating a life insurance policy.” Claim 9 includes the step of “calculating fees,” while claim 1 including “a fee calculator for calculating fees.” Claim 9 recites “calculating credits,” wh ile claim 1 recites “a credit calculator for calculating credits.” Claim 9 includes “storing the policy unit value,” whereas claim 1 includes “digital storage for storing the policy unit value.” And so on. The only difference between the claims is the form in which they were drafted. The district court correctly treated the system and method claims at issue in this case as equivalent for purposes of patent eligibility under § 101.

B.

Turning now to the district court’s ruling on the invalidity of the asserted claims under § 101, we conclude that

the claims cover no more than abstract ideas and therefore do not recite patent-eligible subject matter. Bancorp’s primary argument boils down to the contention thatBANCORP SERVICES v. SUN LIFE 19

because its claims are limited to being performed on a computer, they cannot claim on ly an abstract idea. Even aside from the fact, explained above, that Bancorp’s independent method claims do not require a computer, Bancorp’s position is untenable.

Modern computer technology offers immense capabilities and a broad range of utilities, much of which embodies significant advances that reside firmly in the categoryof patent-eligible subject matter. At its most basic, however, a “computer” is “an automatic electronic device for performing mathematical or logical operations.” 3 Oxford English Dictionary 640 (2d ed. 1989). As the Supreme Court has explained, “[a] digital computer . . . operates on data expressed in digits, solving a problem by doing arithmetic as a person would do it by head and hand.”

Benson , 409 U.S. at 65. Indeed, prior to the information age, a “computer” was not a machine at all; rather, it was a job title: “a person employed to make calculations.” Oxford English Dictionary, supra . Those meanings conveniently illustrate the interchangeability of certain mental processes and basic digital computation, and helpexplain why the use of a computer in an otherwise patentineligible process for no more than its most basic function—making calculations or computations—fails to circumvent the prohibition against patenting abstract ideas and mental processes. As we have explained, “[s]imply adding a ‘computer aided’ limitation to a claim covering an abstract concept, without more, is insufficient to render the claim patent eligible.” Dealertrack, Inc. v.
Huber , 674 F.3d 1315, 1333 (Fed. Cir. 2012).

To salvage an otherwise patent-ineligible process, a computer must be integral to the claimed invention, facilitating the process in a way that a person making calculations or computations could not. See SiRF Tech.,
Inc. v. Int’l Trade Comm’n , 601 F.3d 1319, 1333 (Fed. Cir.BANCORP SERVICES v. SUN LIFE 20

2010) (“In order for the addition of a machine to impose a meaningful limit on the scope of a claim, it must play a significant part in permitting the claimed method to be performed, rather than function solely as an obvious mechanism for permitting a solution to be achieved more quickly, i.e., through the utilization of a computer for performing calculations.”). Thus, as we held in Fort Properties, Inc. v. American Master Lease LLC , the limitation “using a computer” in an otherwise abstract concept did not “‘play a significant part in permitting the claimed method to be performed,’” 671 F.3d 1317, 1323 (Fed. Cir. 2012) (quoting Dealertrack , 674 F.3d at 1333), and thus did not “impose meaningful limits on the claim’s scope,”

id. (quoting CyberSource , 654 F.3d at 1375). The computer required by some of Bancorp’s claims is employedonly for its most basic function, the performance of repetitive calculations, and as such does not impose meaningful limits on the scope of those claims. See Benson , 409 U.S. at 67 (invalidating as patent-ineligible claimed processes that “can be carried out in existing computers long in use, no new machinery being necessary,” and “can also be performed without a computer”).

We agree with the district court that for purposes of § 101 there is no material difference between the claims

invalidated in Bilski and those at issue here. Bancorp

, 771 F. Supp. 2d at 1066. In Bilski , the patent applicant “attempt[ed] to patent the use of the abstract idea of hedging risk in the energy market and then instruct[ed]
the use of well-known random an alysis techniques to help establish some of the inputs into the equation.” 130 S. Ct. at 3231. Here, Bancorp’s pate nts “attempt to patent the use of the abstract idea of [managing a stable value protected life insurance policy] and then instruct the use of well-known [calculations] to help establish some of the inputs into the equation.” Id. As in Bilski , the claims doBANCORP SERVICES v. SUN LIFE 21

not effect a transformation, an d the fact that the required calculations could be performed more efficiently via a computer does not materially alter the patent eligibility of the claimed subject matter. We discern no fault in the conclusion of the district court, Bancorp , 771 F. Supp. 2d at 1066, that the asserted claims do not meet either prong of the machine-or-transformation test—which, while “notthe sole test for deciding whether an invention is a patent-eligible ‘process,’” remains “a useful and important clue, an investigative tool, for determining whether some claimed inventions are processes under § 101,” Bilski , 130
S. Ct. at 3227.

The principal precedent relied on by Bancorp in arguing for patent eligibility is Research Corp. In that case, the asserted patents claimed processes for enabling a computer to render a halftone image of a digital image bycomparing, pixel by pixel, the digital image against a twodimensional array called a “mask.” 627 F.3d at 863. We reversed the district court’s grant of summary judgmentthat the asserted claims were invalid under § 101, concluding that the processes were not “so manifestly” abstract as to override the statutory language of § 101. Id. at 868. In so holding, we observed that the claimed “invention presents functional and palpable applications in the field of computer technology.” Id. We also notedthat “inventions with specific applications or improvements to technologies in the marketplace are not likely to be so abstract” as to be ineligible for patent protection.

Id. at 869.

Research Corp. is different from the present case in two critical respects. First, the claimed processes in Research Corp. plainly represented improvements to computer technologies in the marketplace. For example,as compared to the prior art, the “inventive mask produce[d] higher quality halftone images while using lessBANCORP SERVICES v. SUN LIFE 22

processor power and memory space.” Id. at 865. No such technological advance is evident in the present invention. Rather, the claims merely employ computers to track, reconcile, and administer a life insurance policy with a stable value component— i.e. , the computer simply performs more efficiently what could otherwise be accomplished manually. Bancorp , 771 F. Supp. 2d at 1065.

Second, the method in Research Corp. , which required the manipulation of computer da ta structures (the pixels of a digital image and the mask) and the output of a modified computer data structure (the halftoned image), was dependent upon the computer components required to perform it. See CyberSource , 654 F.3d at 1376 (“[T]he method [in Research Corp. ] could not, as a practical matter, be performed entirely in a human’s mind.”). Here, in contrast, the computer merely permits one to manage a stable value protected life insurance policymore efficiently than one could mentally. Using a computer to accelerate an ineligible mental process does not make that process patent-eligible.

Bancorp additionally relies on SiRF , 601 F.3d 1319,

but that case also does not control the outcome here. In
SiRF , we evaluated the patent eligibility of a “method for calculating an absolute position of a GPS receiver and an absolute time of reception of satellite signals.” Id. at 1331. The GPS receiver, we no ted, was “integral to each
of the claims at issue.” Id. at 1332. Observing that we were “not dealing with a situation in which there [wa]s a method that [could] be performed without a machine,”
and that there was “no evidence . . . that the calculations [could] be performed entirely in the human mind,” we concluded that the claims were eligible for patenting under § 101. Id. at 1333. Bancorp seeks to analogize its

case to SiRF, contending that a computer “plays a significant part” in its claims because they require “precise andBANCORP SERVICES v. SUN LIFE 23

repetitive calculation.” Banc orp Br. 52. That misses the point. It is the management of the life insurance policy that is “integral to each of [Bancorp’s] claims at issue,”not the computer machinery that may be used to accomplish it. See SiRF , 601 F.3d at 1332.

When the insignificant computer-based limitations
are set aside from those claims that contain such limitations, the question under § 101 reduces to an analysis of
what additional features remain in the claims. See Mayo

, 132 S. Ct. at 1297 (questioning, after setting aside the claimed law of nature, “[w]hat else is there in the claims before us?”). The asserted claims require determining values—for example, “an initial value based on a value of underlying securities,” “fee units,” “surrender value protected investment credits,” “an investment value and a value of the underlying securities for the current day,” and “a policy value and a policy unit value for the currentday”—and then “storing,” “removing,” and/or “accumulating” some of those values. ’792 patent col.16 l.55–col.17
l.8. As the formulae in th e specification indicate, the determination of those values, and their subsequentmanipulation, is a matter of mere mathematical computation.

The district court correctly held that without the computer limitations nothing remains in the claims but the abstract idea of managing a stable value protected lifeinsurance policy by performing calculations and manipulating the results. Bancorp , 771 F. Supp. 2d at 1066.Bancorp’s claimed abstract idea impermissibly “preempt[s]” the mathematical concept of managing a stable value protected life insurance policy. Benson , 409 U.S. at 72 (rejecting claims that “would wholly pre-empt the mathematical formula and in practical effect would be a patent on the algorithm itself”); Flook , 437 U.S. at 594 (“[The claimed] process is unpatentable under § 101, notBANCORP SERVICES v. SUN LIFE 24

because it contains a mathematical algorithm as one component, but because once that algorithm is assumed to be within the prior art, the application, considered as a whole, contains no patentable invention.”).

Bancorp asserts that its claims are not abstract because they are limited to use in the life insurance market.

In Bilski the Supreme Court discredited a similar argument, explaining that although some of those claims limited the hedging process to use in commodities and energy markets, “ Flook established that limiting anabstract idea to one field of use or adding token postsolution components did not make the concept patentable.” 130 S. Ct. at 3231. Bancorp further contends that its claims cannot be preemptive because Sun Life alleged that its stable value protected products do not infringe Bancorp’s claims. That argument, while creative, is unpersuasive. The Federal Rules permit a party to plead

in the alternative. See Fed. R. Civ. P. 8(d)(3) (“A party may state as many separate claims or defenses as it has,regardless of consistency.”). Sun Life’s alternative assertion of noninfringement does not detract from its affirmative defense of invalidity under § 101.

Finally, our conclusion is not inconsistent with CLS

, which we decided after hearing oral arguments in this appeal. In CLS , we reversed the district court and held that method, system, and medium claims directed to a specific application of exchanging obligations between parties using a computer were patent eligible under § 101. No. 2011-1301, 2012 WL 2708400, at *10–11. In faulting the district court for “ignoring claim limitations in order to abstract a process down to a fundamental truth,” id. at *11, we explained that the asserted claims in CLS were patent eligible because “it [wa] s difficult to conclude that the computer limitations . . . d[id] not play a significant

part in the performance of the invention or that theBANCORP SERVICES v. SUN LIFE 25

claims [we]re not limited to a very specific application of the [inventive] concept,” id. at *12 (emphasis added).Here, in contrast, the district court evaluated the limitations of the claims as a whole before concluding that they were invalid under § 101. Bancorp , 771 F. Supp. 2d at 1056–57, 1064–66. As we explained above, the computerlimitations do not play a “significant part” in the performance of the claimed invention. And unlike in CLS , theclaims here are not directed to a “very specific application” of the inventive concept; as noted, Bancorp seeks tobroadly claim the unpatentable abstract concept of managing a stable value protected life insurance policy. See

id. at 1066.

Because Bancorp’s asserted claims are directed to no more than a patent-ineligible abstract idea, we affirm the district court’s holding of invalidity under § 101.

C ONCLUSION

We have considered Bancorp’s remaining arguments and find them unpersuasive. We therefore affirm the district court’s judgment that the asserted claims are

invalid.
