A transgenic mouse with enhanced Alzheimer’s Disease related amyloid accumulation in its brain produced by: producing an F 1 generation mouse by crossing a first transgenic mouse whose genome comprises at least one transgene comprising a DNA sequence encoding mutant presenilin M146L operably linked to a promoter with a second transgenic mouse whose genome comprises at least one transgene comprising a DNA sequence encoding APP K670N,M671L operably linked to a promoter, wherein the first transgenic

mouse expresses the DNA sequence encoding the mutant presenilin and wherein the second transgenic mouse expresses the DNA sequence encoding the APP; and selecting from the offspring of the cross, those transgenic mice whose genome comprises at least one DNA sequence encoding mutant presenilin M146L operably linked to a promoter and at least one transgene comprising a DNA sequence encoding APP K670N,M671L operably linked to a promoter, and identifying an F 1 mouse which
express both transgenes such that the F 1
mouse develops accelerated deposition of Aβ in its brain as compared to non

- transgenic mice or either parental mouse.

B
T he invention of the ʼ 094 patent involves doubly transgenic mice having a p articular property of developing an identified symptom of Alzheimer’s Disease on an “accelerated” basis. The invention was conceived by Dr s. Duff and Hardy while both were professors employed by USF. J.A. 3762. At USF, Dr s

. Duff and Hardy worked with Dr . David Morgan and Dr. Marcia Gordon , both of whom were also professors at USF . The role of the latter two scientists , as relevant here, was to conduct (with assistance within their laboratory) the tissue analysis needed to determine , for mice resulting from two gene modifications, whe n in their aging process the mice developed the claimed symptom

. The first litter of mice expressing both of the two transgenes at issue

— a mutant Swedish am yloid precursor protein transgene and a mutant presenilin transgene

— was born at USF on August 21, 19 96

. J.A. 631

– 32, 3890

– 91. B ut time was needed to determine if th o se mice would actually develop Alzheimer’s Disease pathology at an accelerated rate

. During that period of mouse aging, Dr. Hardy change d his employer from USF to Mayo
, and Dr. Duff did the same, in December 1996 , shortly after Dr. Hardy

. The doubly transgenic mice remained at USF after Dr s. Duff and Hardy moved to Mayo. While at Mayo, Dr. Duff continued to oversee the doubly transgenic mouse project

. The day

- day work of caring for the mice, how ever, became the responsibility o f Dr. Gordon in Dr. Morgan’s laboratory

. J.A. 529

. Additionally, Dr. Gordon, at her USF lab, performed immunohistochemistry, or tissue

- examinati on, work on the brains of sacrificed doubly transgenic Case: 22-2248 Document: 37 Page: 4 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 5

mice to identify whether and when the mice developed Alzheimer’s Disease pathology. J.A. 152

– 54, 148

– 50

. An actual reduction to practice of the invention claimed the ’094 patent required construction of an embodiment and recognition that the embodiment worked for its intended purpose. See Cooper v. Goldfarb , 154 F.3d 1321, 1327 (Fed. Cir. 1998); Estee Lauder Inc. v. L’Oreal, S.A.
, 129 F.3d 588, 594

. Dr. Duff marked the facsimile “urgent” because “[t]his

wa s the first time we [the researchers] had seen .

. To show the pathology developing, the facsimile included two figures demons trating that the doubly transgenic mice had amyloid plaques, which play a role in Alzheimer’s D isease, at an age lower than the age at which previously identified mice had such plaques. J.A. 1272

development of amyloid plaques was performed within the Morgan

I n September 1995, Dr. Hardy , while still employed by USF, submitted a grant application to the National Institute of Aging, one of the institutes within the National Institutes of Health (NIH)

. The application , titled “The Role of the Presenilins in Alzheimer’s Disease,” proposed “five[] mutually interlinking projects aimed at elucidating the role of the presenilins in Alzheimer ’ s [D] isease.” J.A. 1793

. The scientists’ already

. The findings and record before us make clear that the grant

- covered project include d the specific doubly transgenic mice that were the subject of what became the ’094 patent (for which the provisional patent application was in preparation , J.A. 1162

– 63 )

. See J.A. 2631

– 36, 2645

– 50 (Stephen Snyder, the relevan t NIH administrator, testifying that the creation and study of the doubly transgenic mice expressing both a mutant Swedish amyloid precursor protein transgene and a mutant presenilin transgene were within the program project grant); see also J.A. 4080. Ju st before the award was made
, the grantee designated in the application was changed from USF to Mayo, to which Dr. Hardy was in process of switching his employment. J.A. 3237; see also J.A. 2089. The grant therefore was made to Mayo, and f unds from the NIH grant

w ere available to Mayo as of October 1, 1996. J.A. 2603

– 04

. Because Mayo was the grantee, but some grant -covered work was to take place at USF, government policies implementing the Bayh

- Dole Act required that Mayo and USF would in due course enter into a subcontract with each other in order for grant money received by Mayo to be paid to USF for the grant -covered work of individuals remaining there, such as Drs. Morgan and Gordon. See J.A. 2607

. In November 1997, more than a year after the NIH grant was awarded, Mayo and USF executed a written subcontract (“ Consortium Agreement ”)
, J.A. 1265

– 70, which states that the agreement was executed to comply with the just cited NIH Guid elines
, J.A. 1265 . The November 1997 agreement states that the start of its “ effective period ”— when its obligat ions took effect

— was September 1, 1997

. And i t expressly provides for treatment of patents and inventions in accordance with the Bayh -Dole Act ( and implementing regulations

- license provision . J.A. 1268.
II
In the present action by USF, the Claims Court granted judgment for the government on the ground that it had a license, under the Bayh

- Dole Act, 35 U.S.C. § 202(c)(4), to have T he Jackson Laborator y practice the patent by creating and using patent

- covered mice (with thetwo transgenes and accelerated plaque development required by the ’094 patent). As relevant here, it is not disputed that The Jackson Laboratory was so practicing the patent and tha t it was doing so for the government and with the government’s authorization and consent. The dispute that is before us is whether the invention was a “subject invention” within § 202(c)(4), which gives the government a license (to practice or have practiced for it) certain federally funded inventions.
A
Before 1980
, federal agencies followed a variety of policies , implemented in provisions of grants or contracts for the furnishing of government funding for research
, to address the disposition of patent rights in inventions resulting from the government

- fund ed research. See
, e.g. , H.R. Rep. No. 96

- 1307, pt. 1, at 3, 5 (1980); S. Rep. No. 96

- 480
, at 2– 3 (1979) ; Technical Development Corp. v. United States
, 597 F.2d 733
, 745

– 46 (C t. Cl . 1979) ; Mine Safety Appliances Co. v. United States
, 364 F.2d 385, 387

– 93 (Ct. Cl. 1966)

. Some of the government patent policies required government- fund recipients to allow the government to own these patent rights. See, e.g
., S. Rep. No. 96

- 480, at 2 (1979). In the Bayh

- Dole Act, with a particular focus on government- funded research by universities and small businesses, Congress sought to reduce the disuniformity of Case: 22-2248 Document: 37 Page: 8 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 9

government policies and also to strengthen the patent rights of government- fund recipients
, under conditions that protected government interests
, in order to incentiv ize commercial develop m ent of patentable inventions into useful products

. The Act itself declares its “policy and objective.” 35 U.S.C. § 200. The Supreme Court noted key purposes: “I n 1980, Congress passed the Bay hD ole Act to ‘promote the utilization of inventions arising from federally supported research,’ ‘promote collabor ation between commercial concerns and nonprofit org anizations,’ and ‘ensure that the G overnment obtains sufficient rights in federal ly supported inventions.’ ” Board of Trustees of the Leland Stanford Junior University v. Roche Molecular Systems, Inc.
, 563 U.S. 776, 782 ( 2011) ( quoting 35 U.S.C. § 200) ( Stanford v. Roche ).“To achieve these aims, the Act allocates rights in federally funded ‘subject invention[s]’ between the Federal Government and federal contractor s.” Id. (alteration by Stanford v. Roche Court ) (quoting § 201(e )). The Act “provides that contractors may ‘elect to retain title to any subject invention.’” Id. (quoting § 202(a) ). A “contractor” is “any person, small business firm, or nonprofit organization that is a party to a funding agree ment.” § 201(c). A “funding agreement ” isany contract, grant, or cooperative agreement entered into between any F ederal agency , other than the Tennessee Valley Authority, and any contractor for the performance of experimental, developmental, or researc h work funded in whole or in part by the F ederal G overnment. Such term includesany assignment, substitution of parties, or subcontract of any type entered into for the performance of experimental, developmental, or research work under a funding agreement as herein defined. Case: 22-2248 Document: 37 Page: 9 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 10

§ 201(b). And a n “invention” includes “any invention ordiscovery which is or may be patentable or otherwise protectable under this title,” and a “subject invention” is “anyinvention of the contractor conceived or first actually reduc ed to practice in the performance of work under a funding agreement.” § 201(d), (e). 1 In light of all of those definitions set out, t he key provision of the Bayh

- Dole Act for this case states : (c) Each funding agreement with a small businessfirm or nonprofit organization shall contain appropriate provisions to effectuate the following : .

. . (4) With respect to any invention in which the contractor elects rights, the F ederal agency shall have a nonexclusive, nontransferrable, irrevocable, paid

- up license to practice or have practiced for oron behalf of the United States any subject invention throughout the world [.] § 202(c)( 4).
B In this case, on the § 202(c)(4) issue in dispute before
us, the Claims Court, before trial, denied USF’s motio n for summary judgment that § 202(c)(4) was inapplicable. University of South Florida, Board of Trustees v. United States
, 146 Fed. Cl. 274, 285

– 89 ( 2019) ( Summary Judgment Ruling ) . The Claims Court subsequently denied USF’s motion in limine to exclude t estimony of Drs. Gordon and Morgan on that issue

. University of South Florida, Board of Trustees v. United States , 154 Fed. Cl. 145, 147

– 48 (2021). The Claims Court then held a trial
, which addressed several

. That language is not applicable here. Case: 22-2248 Document: 37 Page: 10 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 11

issues, including the license issue. After trial, the Claims Court determined that § 202(c)(4) applied , giving the government a license
, and on that basis the court entered judgment for the government

. Claims Court Decision , 1 62 Fed. Cl. at 60

. The Claim s Court made finding s of fact confirming the events and actions described supra

. S ee id. at 60 –63 . The Claims Court also described certain documents indicating that USF set up internal accounts associated with the NIH grant project and expected money from that grant partially to fund at least Dr. Gordon’s salary

. I d. at 62

– 63 ; see , e.g. , J.A. 2050– 58 , 2086, 3860 . Relatedly, the Claims Court recited testimony from Dr. Morgan and Dr. Gordon about when USF actually receiv ed grant money, w hich included testimony about the difficulty of recalling precisely whatoccurred two decades earlier and testimony about the system of USF “ ‘underwriting’” salary and other expenses and getting reimbursed for the “‘advance’” once grant money covering the earlier work eventually arrived. Claims Court Decision , 162 Fed. Cl. at 62

– 63 ; see , e.g. , J.A. 521 –26
, 54 5– 54 , 56 5– 69, 59 2–98 (Dr. Morgan) ; J.A. 623

– 29 (Dr. Gordon)

. With respect to USF’s receipt of grant money from Mayo, t he Claims Court clearly found that Mayo “paid for the work done by Dr. Gordon at USF with the NIH grant funds ,” including (what is crucial here) the April 1997 work

. Claims Court Decision , 162 Fed. Cl. at 65. USF nowhere disputes that finding on appeal to the extent it

means that grant funds eventually went from Mayo to USF to pay for the April 1997 work
, though not necessarily at the time of the work or, indeed, before Mayo and USF entered into the formal contract later that year

. G iven the evidence recited thereafter in sup port, the Claims Court’s findin g may mean no more than that. Id. The Claims Court went on to say that “[t]he greater weight of the trial testimony also established that [USF] was using N IH funds by December 1996 to pay for costs associated with Case: 22-2248 Document: 37 Page: 11 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 12

conductin g the immunohistochemistry work that was a ke y part of the research that led to the ’094 patent.” Id. (emphasis added). That statement suggests a finding that USF received money from Mayo by December 1996, but the correctness of that interpretation of the statement is less than clear , at least because of the two citations immediately following it

— which suggest the scenario in which USF was “using NIH funds” in an accounting sense , i.e.
, itself pay ing for the work in the expectation of being reimburse d eventually by NIH money from Mayo
, which in fact occurred. Id. Timing of funds transfer aside, the Claims Court’s key finding was that “beginning in October 1996, [USF] operated [in the relevant work on the invention] pursuant to an implied contract with the Mayo Clinic for grant funds under the ” NIH grant. Id. The Claims Court found that the evidence established an implied

- in

- fact contract ( a meeting of the minds inferred from the surrounding circumstances )
, stating: “R egardless of whether [USF] underwrote those funds for a time before money flowed from the Mayo Clinic,it is clear in the record that [USF] had a ‘tacit understanding’ with Mayo that the funds would ev entually arrive .” Id. at 66 (quoting Atlas Corp. v. Un ited States
, 895 F.2d 745, 754 (Fed. Cir. 1990))

. Although the government argued in the alternative that there was an implied

- in

- law contract between Mayo and USF

- Trial Br. at 10

– 11, Claims Court Decision (March 31, 2022)
, ECF No. 279 , the Claims Court had no need to address, and did not address, that argument (which the government has not renewed on appeal). Based on its findings, t he Claims Court determined that USF was a “contractor ” having a n implied

- in

- fact subcontract that was a “funding agreement ”; the invention was an “invention of the contractor , ” given the assignment to USF; and the invention was a “subject invention ” in tha t it was “ first actual ly reduc ed to practice ” in April 1997 “ in Case: 22-2248 Document: 37 Page: 12 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 13

the performance of” t he funding agreement. Claims Court Decision , 162 Fed. Cl. at 66

– 67. The government therefore had a license under § 202(c)(4) to practice the ’094 patent, or have the pat ent practiced for or on behalf of it by The Jackson Laboratory , as asserted by USF

. Id. at 67. That conclusion required judgment for the government against the claim under 28 U.S.C. § 1498(a)

. III
We decide legal issues presented by the Claims Court decision de novo, and we review its factual findings for clear error. Gaylord v. United States , 777 F.3d 1363, 1367 (Fed. Cir. 2015). “ A finding is ‘ clearly erroneous ’ when although there is evidence to support it, the reviewing court on the entire evidence is left with the definite and firm conviction that a mistake has been committed.” United States v. United States Gypsum Co. , 333 U.S. 364, 395 (1948); see Anderson v. City of Bessemer City , 470 U.S. 564, 573

– 74 (19 85); Bitma nagement Software GmBH v. United States
, 989 F.3d 938, 94 8 (Fed. Cir. 2021); Oliveira v. United States
, 827 F.2d 735, 742 (Fed. Cir. 1987)

. A We proceed on the basis of t he following facts
, reflected in findings of fact by the Claims Court that are not clearly erroneous based on the record

. The April 1997 work that first actual ly reduc ed the ’094 patent invention to practice

was covered by the NIH grant. Mayo and USF entered into an express subcontract in November 1997 whereby Mayo would pay USF money received from NIH under the grant for work covered by the grant. USF in fact accepted payment from Mayo, using funds from the NIH grant, for the April 1997 work at issue

. See
, e.g., Claims Court Decision
, 162 Fed. Cl . at 64. On appeal, USF presents no substantial challenge to any of those findings of fact. USF does present a factual challenge regarding when Mayo paid NIH money to USF for the April 1997 work

. Case: 22-2248 Document: 37 Page: 13 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 14

USF argues that the record makes it clear that USF did not receive such money from Mayo at the time of the April 1997 work, or at any time before Mayo and USF entered into the express subcontract in November 1997

. The governmentinsists that the Claims Court found otherwise and had adequate evidentiar y support to do so.
We do not resolve this dispute. Specifically, w e do not decide whether the Claims Court even made such a finding

— or whether, instead , it is best understood as having found only ( what is not disputed on appeal ) that the April 1997 wor k was paid for by Mayo with NIH funds at some time
, e.g. , after Mayo and USF signed the November 1997 subcontract . Nor do we decide whether any such finding would be sustainable under the clear

- error standard of revie w applied to the record as a whole

— or whether, instead, the record must be read as showing simply that USF advanced the funding at issue ( e.g. , for salaries) and only laterreceived what amounted to reimbursement for those advances when it received NIH money from Mayo upon the signing of the November 1997 express subcontract.
Besides accepting the above

- identified facts clearly established in the trial court, w e proceed by accepting, for purposes of this appeal, USF’s position on the timing -ofpayment issue. That is, we accept that USF receive d NIH money from Mayo

— including money for the April 1997 work

— when the November 1997 express subcontract was in place and not earlier

. B
The question to be decided , on that basis, is whetherthe April 1997 work (the first actual reduction to practi ce)

— for which USF in fact received government funds supplied, through Mayo, by the NIH grant

— was “in the performance of work under a funding agreement .” 35 U.S.C. § 201(e). If so, the government had the license, under § 202(c)(4), that defeats USF’s infr ingement claim here. Case: 22-2248 Document: 37 Page: 14 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 15

The Claims Court answered the question in the affirmative. USF’s argument for reversal of the Claims Court’s judgment has two necessary premises

. The first is that any “funding agreement” adequate to trigger § 20 2(c)(4) must be in place at the time of the relevant work (here, a first actual reduction to practice in April 1997 ) , so that the November 1997 subcontract (whose execution and effective date were later than April 1997 ) does not suffice to trigger § 202( c)(4) . The second is that there was no legally adequate implied agreement at the time of the April 1997 work(indeed, at all), and the Claims Court’s contrary determination must be reversed

. We conclude that USF’s first premise is legally incorrect in the circumstances presented here , so the November 1997 subcontract is adequate to give the government a § 202(c)(4) license. Although the Claims Court decided the case on the implied

- contract ground, and the parties have accordingly focused their arguments on that ground, the underlying premise of a requirement of a contract in effect at the time of the relevant work is logically necessary to the bottom- line result of no license that USF urges . The validity of this premise presents a legal issue requiring determination of no facts in this case other than the ones identified above that are beyond reasonable dispute here. In these circumstances, we may address this legal premise
, the rejection of which is a ground for affirmance, with out further examining the extent to which the government has briefed the issue

. On the factual premises stated above, USF accepted (received) NIH funds from Mayo, pursuant to the November 1997 subcontract to the NIH grant, to pay for the April 1997 work, as well as ongoing work. We conclude that t he April 1997 work
, i.e.
, the first actual reduction to practice
,was “in the performance of work under a funding agreement,” § 20 1(e)— a subcontract between Mayo and USF to the NIH grant (the lat ter a funding agreement of NIH with Mayo ). The statutory terms are broad enough to cover the facts on which we decide this appeal.
The November 1997 agreement between Mayo and USF was a “ funding agreement ,” § 201(b)

. The original NIH grant awarded to Mayo was itself a funding agreement because it was a grant entered into between NIH and Mayo for the performance of experimental, developmental, or research work funded in whole or in part by the f ederal government , id. T he November 1997 a greement , then, was a funding agreement because it was a n express “ subcontract ” entered into for the performance of experimental, developmental, or research work under the 1996 NIH grant
, id.
The work of tissue analysis (constituting th e first actual reduction to practice in April 1997) was covered by the 1996 NIH grant. The November 1997 a greement signed by USF and Mayo did not limit the scope of the NIH grant. See J.A. 1265

– 70

. The April 1997 work was in “ the performance of work under [ those ] funding agreement [s]” pursuant to a recognized meaning of “under” applicable to the statutory phrase , § 20 1 (e) : I t was substantively covered by both, and (on the facts we accept) both provided money to
pay for it. See Random House Webster’s Unabridged Dictionary 2059 (2d ed. 2001) (defining “under” as “14. in accordance with”); Bryan A. Garner
, Garner’s Dictionary of Legal Usage 910, 737

– 38 (3d ed. 2011) (stating that “under Case: 22-2248 Document: 37 Page: 16 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 17

is preferable to *pursuant to when the noun that follows refers to a .

. . contract ual provision,” and defining “pursuant to” as “ (1) in accordance with; (2) under; (3) as authorized by; or (4) in carrying out” ).
USF opposes this conclusion on the basis of a time

based limitation it urges is present in the Bayh

- Dole Act provisions

. USF argues that the November 1997 agreement is legally insufficient , even if it provided funds to pay for the pre -agreement , April 1997 work
, because it was entered into in November 1997 and had an effective date in September 1997
, after the April 1997 work. We reject this suggested temporal limitation on the scope of the relevant Bayh -Dole Act language.
The Act says that “funding agreement” includes “any

. . . subcontract of any type ” for the performance of work under a funding agreement. § 201(b) . That breadth

- indicating language supports inclusion within the provision of a subcontract that provides for , among other things, payment for work already performed before the subcontract is executed or its “effective” date (when its obligations take effect
, see Date
, Black ’s Law Dictionary (11th ed. 2019) (defining “effective date” )). A contract may provide for payment for work previously done at least where, as here, the contract also pays for work yet to be done . Restatement (Second) of Contracts § 80 ( American Law Institute 1981) (“(1) There is consideration for a set of promises if what is bargained for and given in exchange would have been consideration for each promise in the set if exchanged for that promise alone. (2) The fact that part of what is bargained for would not have been consideration if that part alone had been bargained for does not prevent the whole from being consideration .”); 17 C.J.S. Contracts § 174 (2023) (“ A promise founded on consideration which is partly past and partly present or executory is enforceable, although in a sense no resort to the past consideration need be had as the new or executory consideration is con ceptually adequate to support enforceability of the contract. ”); 17A Am. Jur. 2d Case: 22-2248 Document: 37 Page: 17 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 18

Contracts § 147 (2023) (“ Where the consideration is partly past and partly future, a single promise as to both will be sustained.”); see also Hackin v. Pioneer Plumbing Supply Co. , 457 P.2d 312, 318 (Ariz. Ct. App. 1969); Jim Murphy & Assoc iates , Inc. v. LeBleu , 511 So. 2d 886, 891 (Miss. 1987); Johnson v. Hazaleus , 338 P.2d 345, 347 ( Okla. 1959); Kahn v. Lischner , 275 P.2d 539, 543 ( Cal. Dist. Ct. App. 1954); W. T. Rawleigh Co . v. Miller , 73 P.2d 552, 554 (Mont. 1937).
USF’s own position that Mayo paid for the April 1997 work with the relevant NIH grant funds after the November 1997 contract was executed or took effect confirms th at such backward

- reaching payment is a recognized contract practice. And it confirms that the November 1997 contract included Mayo’s promise to pay for the April 1997 work with the NIH funds

. USF nowhere suggests that Mayo did

or properly could pay for t hat work with the NIH grant fun ds outside a subcontract, as Mayo was obligated to enter into subcontracts for funded work with its consortium partners. This understanding of the November 1997 agreement
, and of its meaning for the Bayh

- Dole Act, is consis tent with the agreement’s provision stating that the “effective period of this Agreement shall be from September 1
, 1997
, through August 31, 1998, unless otherwise provided for by modification in this Agreement.” J.A. 1266. The “effective period” merely identifies when the obligations (specified elsewhere in the contract) are binding

. See
, e.g. , 17A Am. Jur. 2d Contracts § 323 (2023) ( equating “effective date” with the date on which “a written contract becomes binding”); 1 Albert H. Kritzer et al., Inter national Contract Manual § 19:23 (2023) (“[T] he effective date of the contractwill ordinarily be the date on which the contract first creates a legal obligation on both parties .”) ; cf. Hamilton v. Lanning , 560 U.S. 505, 518 (2010) (explaining that “effect ive date” of plan of reorganization is when plan is adopted “and becomes binding”). W hen one party’s work performed Case: 22-2248 Document: 37 Page: 18 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 19

before the contract took effect is included in what the other party agrees to pay for ( along with yet- to

- be

- performed work from the first party)
, that recognized type of contract does not turn already

- completed pre

- effective

- date work into work the first party was obligated to perform , when th ere had been no obligation to perform it when it was perform ed— as USF insists is the case for the April 1997 work. Of course, such a contract does create an obligation re lating to that work

— at least the second party’s voluntarily undertaken obligation to pay for that work (or do other things because of th at work )—b ut the already

- completed performance of the first party’s work remains not obligatory. Thus, t he start of the “effective period” on September 1, 1997

— for a one

- year period to align with NIH’s designation of the second year of the NIH grant —does not exclude the April 1997 work from being under the formal agreement , in that it was part of what Mayo undertook to pay for and did pa y for with the NIH grant funds through the formal contract.
U nderstanding the Bayh

- Dole Act la nguage to embrace such past

- work funding fits the statutory context. To begin with, consistent with the Act, our understanding respects, rather than overrides, the patent owner’s choice whether to enter into a subcontract and on what terms, including what work will be paid for under it. Here, on the facts that are the basis for our decision, and against the well

- known background of the Bayh -Dole Act regime, USF entered into the November 1997 agreement ( which expressly provides for application of the Act ) and accepted the NIH funding from Mayo for the April 1997 work under th at agreement

. The statutory interpretation we adopt fits the statutory context more generally. It reflects the stated statutory policy to “ensure that the G overnment obtains suf ficient rights in federal ly supported inventions
, ” § 200, where the patent owner accept s federal funds under an agreement that invokes the Act

. Even b efore enactment of the Bayh

Dole Act, this court’s predecessor had given a “liberal Case: 22-2248 Document: 37 Page: 19 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 20

construction” to “ the general phrase ‘in the performance of’ ” used in some government funding contract s , explaining that the con struction ensure s that, in such circumstances, the public, having paid for an invention, would “‘not again be taxed for its use, nor excluded from its use [,] nor permitted to use it upon restrictive conditions advantageous to no one but the patent owner.’” Technical Development , 597 F.2d at 745 ( quoting Mine Safety Appliances
, 364 F.2d at 392). This policy applies even when the agreement provi des for payment of government funds for pre -agreement work having the defined relationship to the invention ( here, that the government

- funded work i ncludes the first actual reduction to practice of the invention ).
This conclusion is strongly bolstered by t he record in this case, which suggests that what occurred here is not an

un common fact pattern in government funding of research conducted in part by non

- grantee members of a consorti um called for in a government grant . Specifically, the record makes clear that subcontracts are commonly not executed until some time after the grant is awarded, yet the grant

covered work proceeds without waiting for the inking of a subcontract. The commonplace nature of this scenario suggests that, i f USF’s time

- re strictive view of the Act were adopted, one or more policies of the Act might be impaired

— e.g. , by the government insisting, in order to protect its rights, that research by a consortium member be postponed until a subcontract was executed

. Our understand ing of the statute avoids such impairment by focusing on the facts of agreement, coverage, and actual funding, whether forward

- looking or backward -looking.
S everal witnesses testified , without contradiction, t hat it was common for there to be a delay in su bcontracting after award of a government grant . J.A. 136 (Dr. Duff, stating that subcontracts are “very often delayed ”); J.A. 523 (Dr. Morgan, stating that subcontracting “usually does not occur immediately upon the award of the grant itself ”) ; see also J.A. 624

– 25 (Dr. Gordon stating “[u]niversity Case: 22-2248 Document: 37 Page: 20 Filed: 02/09/2024UNIVERSITY OF SOUTH FLORIDA BOARD OF TRUSTEES v. US 21

bureaucracy” slowed down the agreement between USF and Mayo) ; J.A. 260 7–11 ( Mr. Snyder discussing post

award subcontract ing); NIH Grant Policies
, supra (contemplating the same ). Other aspects of the r ecord

— e.g. , the absence in the record of any written subcontract for more than a year after the NIH grant award, Dr . Morgan’s own uncertainty about when money actually flowed from Mayo to USF
, the evident expectation by USF that it would receive grant fund s— tend to confirm that, in practice, grantees and their consortium institutions often do not place high priority on speedily getting a formal sub contract executed after a grant is awarded. At the same time, it is of great significance for the advancement of useful knowledge ( here
, in medic ine ) and for many particular grant projects that research continue without interruption
, suggesting that all persons concerned, including the government, would expect the gr ant

covered work to proceed immediately upon award of the grant , without awaiting a formal subcontract. Notably, the record in this case indicates that it was clear from the outset of the NIH grant project that the USF work that was part of it would have to proceed without delay

. T he first litter of the doubly transgenic mice was born in August 1996, just before the late

- September NIH award . T he responsibility for the colony remained at USF, even after Dr. Duff moved to Mayo in December. J.A. 529

. Dr. Gordon and her USF colleagues c ould not have wait ed to complete the work of caring for the mice

. Dr. Gordon was also responsible for the immunohistochemistry work on the brain s of sacrificed mice in the colony to identify the develop ment of Alzheimer’s Disease pathology. J.A. 152

– 54, 148

– 50. This work was highly time sensitive : A core objective was to determine the timing of such development , and the immunohistochemistry test ing therefore had to be gin, and it did begin, no more than a few months after the birth of the mice. See Nature Medicine Article at 97

– 98; J. A

. 3231

- old doubly transgenic mice) . S uch immediate performance of the work, beyond being necessary as a scientific matter, was also important for grant administration, as NIH had to decide each year whether to renew the funding of the grant, requiring an evaluation of progress in the project

. See J.A. 2 616

. For all of the foregoing reasons, we reject USF’s reliance on the November 1997 agreement’s effective date and execution date as a basis for not recognizing it as a funding agreement sufficient to give rise to the licens e rights of the government under § 202(c)(4). The Claims Court’s judgment of non

- infr ingement is correct on this ground. Given this conclusion, it is not necessary that we address whether the Claims Court’s finding of an implied

- in

- fact contract was correct.
IV The judgment of no liability for infringement by reason of a license is affi rmed

. The parties shall bear their own costs.
