This suit undеr the Freedom of Information Act (“FOIA”) requires us to determine the proper application of the “trade secret” exemption to FOIA’s general requirement that the federal government release information to the public. We have jurisdiction pursuant to 28 U.S.C. § 1291 and affirm.
I
Greg Herrick, the plaintiff and appellant in this case, sought information from the Federal Aviation Administration (“FAA”) regarding a 1936 antique F-45 aircraft manufactured by Fairchild Engine and Airplane Corporation (“Fairchild”). In November 1997 Herrick sent a FOIA request to the FAA for plаns and specifications submitted by Fairchild in 1935 to the Civil Aeronautics Agency (“CAA”), the predecessor to the FAA. Herrick has stated that he desires this information for the purpose of restoring the F-45 that he owns.
Fairchild had submitted these materials to the CAA in order to receive an “Approved Type Certificate.” Obtaining such a certificate is a requirement for the construction, sale, and use of a new type of aircraft in the United States. After the agency has reviewed the documents related to the aircraft design, conduсted (or required the manufacturer to conduct) tests, and determined that the aircraft is airworthy, the agency grants a type certificate that gives the manufacturer the legal right to produce the new type of aircraft.
See United States v. S.A. Empresa de Viaeao Aerea Rio Grandense,
Herriсk made the November 1997 request in a letter to the FAA, to which the FAA replied in December that it would be unable to release the materials because they were exempt from FOIA as “trade secrets” pursuant to 5 U.S.C. § 552(b)(4). Instead, the FAA instructed Herrick to contact the owner of the materials — listed in its records as Fairchild Industries, Inc., based in Maryland' — to obtain permission for their release. Herrick attempted to contact Fairchild Industries but determined that the company had since been merged and then sold to a new corporation, The Fairchild Corporation.

In January 1998 Herrick appealed the FAA’s adverse determination, statipg that counsel at The Fairchild Corporatidn had told him that all Fairchild aircraft archive memorabilia had been donated to the Smithsonian Institute in Washington, D.C.

In response, the FAA stated in October 1998 that they
Herrick filed suit in district court, argu~ ing that the FAA had improperly applied the "trade secrets" exemption to the materials in question and that the FAA therefore had a legal duty under FOIA to release the materials. Following discovery, the parties filed cross-motions for summary judgment. The district court granted the FAA summary judgment, holding that the "trade secrets" exemption applied to the materials. Herrick appeals.
II
We begin with an overview of FOIA and the relevant principles of statutory interpretation. We then examine whether the documents in question qualify as "trade secrets" under FOIA.
A
FOIA, enacted in 1966, provides the public with a right of access to federal agency records, a right of access that is subject to nine exemptions. See 5 U.S.C. § 552. Agencies are required to make all records accessible to the public upon request. § 552(a)(3). Deadlines are set for the time within which the agency must respond tо record requests, § 552(a)(6), and fees may be charged for reasonable copying and search costs, § 552(a)(4)(A). Federal courts are granted the authority to enjoin the agency from withholding records. § 552(a)(4)(B). However, agencies need not release records that fall within the nine specified exemptions listed in 5 U.S.C. § 552(b); these exemptions include classified documents, personnel records, exemptions under other statutes, trade secrets and other confidential commercial information, and law enforcement records. § 552(b). For the purposes of this case, the only relevant exemption is "Exemption 4," which applies to "trade secrets and commercial or financial information obtained from a person' and p~rivileged or confidential." § 552(b)(4).
FOIA's purpose is "to ensure an informed citizenry, vital to the functioning of a democratic society, needed to check against corruption and to hold the governors accountable to the governed." Anderson v. Dep't of Health & Human Servs.,
In any' FOIA action challenging an agency decision to withhold records, the district court reviews de novo the agency's decision nоt to disclose. Id. (citing DeSalvo v. I.R.S.,
We review the district `court's grant of summary judgment de novo. Simms v. Oklahoma ex rel. Dep't of Mental Health & Substance Abuse Servs.,
"If there is no genuine issue of material fact, we determine whether the district court correctly applied the substantive law." Id. In particular, when a district court has granted summary judgment in favor of a government agency in a FOIA suit, we "must review de novo the district court's legal conclusions that the requested materials are covered by the relevant FOIA exemption." Anderson,

Grounding its decision to withhold the records on Exemption 4 of FOIA, the FAA determined that the records in question are "trade secrets" protected by thаt exemption. We have defined a "trade secret" for the purposes of FOIA as "a secret, commercially valuable plan, formula, process, or device that is used for the making, preparing, compounding, or processing of trade commodities and that can be said to be the end product of either innovation or substantial effort." Id. at 944 (quoting Pub. Citizen Health Research Group v. Food & Drag Admin.,
On appeal, Herrick raises three primary arguments. He argues first that the documents here no longer constitute a "trade secret" because to be a trade secret the documents must be owned by someone and the FAA has not shown that The Fairchild Corporation is the "owner" of the documents. Second, he argues that the "secret" status of the documents was lost when Fairchild granted the FAA permission to release the documents to the public in 1955. Finally, in respоnse to the government's argument that the trade secret status of the documents was restored when Fairchild Corporation refused to release the documents to Herrick, Herrick argues that this current refusal did not restore the exempt status of the documents because, again, The Fairchild Corporation is not their owner. 3
C
We first address Herrick's argument that the government must show "ownership" by a party for the trade secret exemption to apply. Herrick asserts that The Fairchild Corporation, the party currently claiming the documents are still subject to trade secret protection as to which it has proprietary rights, is not the owner of the documents. He therefore argues the documents cannot be a "trade secret" because the essence of a trade secret is "ownership" by some party and
We first note that Herrick’s argument that The Fairchild Corporation can only demonstrate ownership of the documents by showing a transfer of the type certificate in conformance with the FAA regulations is misplaced. Ownership of the type certificate, which grants permission to manufacture the aircraft in questiоn, is not the issue. Rather, the issue is ownership of the documents and materials submitted as part of the application for that certificate. Thus, the FAA may show that The Fairchild Corporation owns the documents by showing a corporate “chain-of-ownership” of the documents from Fair-child, the original owner and submitter of the documents.
In the course of the instant case the FAA has provided a substantial amount of evidence as to the corporate succession from Fairchild in the 1950s to The Fairchild Corporation today, including documentation as to mergers, name changes, and reincorporation. The FAA need not show that, in each of these transactions, the ownership of these particular documents was specifically mentioned and transferred; such a requirement would be overly burdensome in these circumstances. Instead, the FAA need" only show that there was a corporate successor that received the assets of the prior corporation, and the FAA has met that burden.
Herrick argues there is evidence that the documents in questiоn might have been transferred to a different corporation in the past. In particular, Herrick cites a district court opinion in which the court made a finding of fact that in the 1980s Fairchild sold off its airplane manufacturing business to another corporation.

See In re Fairchild Indus., Inc.,
The evidence Herrick relies upon is hearsay. It is an out-of-court written statement by a judge now offered to prove the truth of the matter asserted—in this case, that the Fairchild subsidiary held all of Fairchild’s aircraft manufacturing business and was sold to another corporation.
See
Fed.R^Evid. 801(c). It is therefore inadmissible unless it falls within one of • the hearsay exceptions.

Fed.
Rule 803(8) was not intended to allow the admission of findings of fact by courts. Rule 803(8) is limited to investigations: “A judge in a civil trial is not an investigator, rather a judge.”
Nipper v. Snipes,
Finally, policy reasons counsel against the admission of prior judgments or findings of fact under Rule 803(8). Juries are likely to give disproportionate weight to such findings of fact because of the imprimatur that has been stamped upon them by the judicial system.
Nipper,
We thus join the Fourth and Eleventh Circuits in holding that the public records exception of Rule 803(8) does not apply to judicial findings of fact in a prior, unrelated case.
Jones,
Because Herrick’s proffered evidence as to the ownership of the documents is inad

Herrick points to a 1955 letter from Fairchild that “authorized [the CAA] to loan data from [its] files for use in making repairs or replacement parts for aircraft produced by Fairchild without requiring the individual to obtain specific requests from us.” (1 Appellant’s App. at 58.) According to Herrick, this removes the “secret” nature of the information in question such that the materials are no longеr “trade secrets.”
In response the government argues that only actual public disclosure of the documents would eliminate their “secret” nature. To support this position, the government cites case law for the proposition that “waiver” of FOIA exemptions only occurs when the plaintiff is able to show that specific documents have been released to the public.
See Pub. Citizen v. Dep’t of State,
This response confuses two different issues. “Waiver” doctrine stands for the proposition that “the government cannot rely on an otherwise valid exemption [to FOIA] to justify withholding information that has been ‘officially acknowledged’ or is in the ‘public domain.’ ”
Davis,
The purpose of Exemption 4 is “to protect the confidentiality of information which is obtained by the Government ..., but winch would customarily not be released to the public by the person from whom it was obtained.”
Critical Mass Energy Project v. Nuclear Regulatory Comm’n,
We therefore conclude that where the submitter or owner of documents held by the government grants the government permission to loan or release those documents to the public, those documents are no longer "secret" for purposes of Exemption 4. In such a situation, FOIA creates an obligation for the government to release the documents. 9 When Fairchild granted permission to the CAA to loan the documents to individuals who requested them, for purposes of FOIA the documents ceased to be "secret."
E
In rejecting Herrick's argument that the documents were no longer "trade secrets" because of the 1955 grant of permission, the district court concluded instead that "[t]he authorization of Fairchild to disclose, given in 1955, has since been reversed by the corporation" (2 Appellant's App. at 461), referring to The Fairchild Corporation's refusal to grant the FAA permission to release the materials to Herrick. 10
Ill
We AFFIRM the judgment of the district court.
Notes
. Throughout this opinion, "Fairchild” is used to refer to the corporation (Fairchild Engine and Airplane Corporation) that produced the aircraft in the 1930s, submitted the type certificate, and, as discussed below, granted permission in 1955 for the documents to be loaned to . the public. "The Fairchild Corporation” refers to the currently existing corporation that claims proprietary rights to the trade secret in question.
. Later investigation by the FAA determined that the Smithsonian was not in possession of the relevant type certificate materials.
. Before the district court, Herrick argued that the documents were not commercially valuable. At oral argument, Herrick conceded this point. Herrick makes no argument that any of the other elements of the Anderson definition are not met.
. Herrick’s other evidence—including an affidavit that provides hearsay evidence of a statement by an officer of The Fairchild Corporation in a shareholder meeting—is insufficient to meet his burden of avoiding summary judgment in favor of the government.
. Our only other alternative for admitting this evidence would be for the district court or for us to take judicial notice of the opinion of the district court of the Northern District of Florida. However, one of the requirements for judicial notice is that the evidence in question is "not subject to reasonable dispute.” Fed. R.Evid. 201(b). Certainly the issue of whether the subsidiary was the only part of Fair-child involved in aircraft manufacturing and therefore whether it can be inferred that the subsidiary owned the documents is not one that is “not subject to reasonable dispute.” Bоth parties dispute that question.
. The residual hearsay exception in Federal Rule of Evidence 807 does not apply in this case because there is no evidence that Herrick provided the government with notice of his intent to use the district court opinion "sufficiently in advance of the ... hearing to provide the [government] with a fair opportunity to prepare to meet it,” including providing "prior notice of [his] intention to utilize [the residual] exception” to the prohibition on hearsay.
United States v. Zamora,
. Indeed, Fairchild's 1955 letter indicates that the company would have been equally willing to release the information itself to any member of the public who requested it and that the purpose of the letter was instead to deflect such requеsts to the government. (See 1 Appellant's App. at 58 (instructing the government that it can release the information to the public "without requiring the individual to obtain specific requests from us'').)
. Although Fairchild authorized the government to "loan" the materials to the public-rather than "release" them-this fact does not change the analysis. For example, if Fair-child had directly loaned the materials to members of the public itself, the information would have entered the public domain, notwithstanding the temporary nature of any "loan." During the course of the "loan" the borrower could have copied, disseminated, used, or otherwise appropriated the materials in a manner such that the secret nature of the materials would have been eliminated. In fact, Fairchild's grant of permission was intended to allow third parties to use the materials to make "repairs or replacement parts" (1 Appellant's App. at 58), such that the secret information in the materials was very likely to be either copied for future use or to be used to create replacement parts.
. A contrary conclusion would lead to a curious outcome under FOIA. If a "trade secret" could remain "secret" even when the owner and submitter of the information indicated to the government that it could be released, the government could then continue to refuse to disclose the information under FOIA indefinitely-using Exemption 4 and the fact that the information had never been released to the public as its rationale-even though the submitter of the information no longer wished the information to remain secret.
. We note that the district court's conclusion assumed the answer to two additional legal questions.
First, the district court assumed that-where documents that have lost their status as "trade secrets" under Exemption 4 because the owner of the information has granted permission for the documents to be released to the public-those documents may have their trade secret status restored through revocation of the grant of permission. On appeal Herrick has not challenged the legal conclusion that it might be possible for The Fairchild Corporation to revoke the permission to loan the documents to the public or that such a revocation would restore the secret nature of the documents. We therefore decline to overturn the district court's judgment on a point that the plaintiff has failed to challenge on appeal. See Hernandez v. Starbuck,
Second, the refusal by The Fairchild Corporation to grant permission to release the documents to Herrick only occurred after Herrick had initiated his request for the type certificate materials. If a document's status under FOIA is determined at the time the document is requested, then The Fairchild Corporation could not have restored the status of the docu-
