Patent Secrecy Orders and Applicant Rights: National security restrictions and the cost of delayed disclosure
Executive Summary: Patent secrecy orders can restrict disclosure of an invention and delay publication or patent issuance even when the invention was privately developed without government funding. 35 U.S.C. § 181. Their consequences extend beyond patent prosecution to financing, licensing, product development, and international protection. An effective response requires careful review of the operative order and its permits, continued attention to prosecution deadlines, and an inventory of prior disclosures to determine the applicable notification and reporting obligations. Foreign filing and PCT practice require particular care because filing an international application with the USPTO does not itself authorize transmission abroad. Applicants may seek disclosure permits, modification, or rescission, but removal of an order does not independently eliminate classification restrictions. 37 C.F.R. §§ 5.1(e), 5.4–5.5 (2026). Compensation and patent-term adjustment provide potential relief, subject to distinct eligibility requirements, procedures, and limitations; neither should be assumed to restore lost commercial opportunities or compensate automatically for the entire period of secrecy. See 35 U.S.C. §§ 154(b), 183. The article advocates clearer notices, more predictable processing of permit requests, meaningful review of continuing restrictions, and more usable compensation procedures to protect national security while reducing avoidable harm to applicants, particularly independent inventors and smaller businesses.
I When Patent Disclosure Creates a National Security Concern
Consider a small company developing a sensing technology for industrial equipment. The company files a patent application, begins discussions with investors, and plans to seek protection abroad. Its engineers recognize possible military uses, but the business has no defense contract and has received no government funding. A secrecy order then arrives. Counsel must determine what the company may disclose, whether its international filing plans can proceed, and how to preserve an application that may still require active prosecution.
The statutory system permits that situation. Under 35 U.S.C. § 181, the government may restrict disclosure of an invention and withhold application publication or patent issuance when the statutory national-security conditions are met, including for inventions in which the government has no property interest. The consequences can extend beyond the patent file to the communications on which financing, licensing, and product development depend. Understanding the order therefore requires attention to the applicant’s commercial plans as well as its prosecution docket.
The USPTO’s updated invention-secrecy guidance provides a useful entry point. It explains national-security screening and directs applicants to the governing statutes and regulations. Those authorities establish both substantial restrictions and procedures for seeking relief. Effective representation requires using those procedures while continuing to satisfy the obligations that remain in force. See U.S. Patent & Trademark Off., Invention Secrecy—Licensing and Review (Sept. 23, 2026), https://www.uspto.gov/patents/invention-secrecy.
II The Legal Foundation and the Applicants Affected
Section 181 addresses two categories of inventions. When the government has a property interest, the interested agency can notify the Commissioner for Patents that publication or disclosure might harm national security. When the government lacks such an interest, the statute provides for agency inspection and a determination that disclosure would be detrimental to national security. The Commissioner then issues the order and withholds publication or issuance. The agency’s security determination and the USPTO’s administration of the patent application perform distinct functions. 35 U.S.C. § 181; 37 C.F.R. § 5.2(a) (2026).
Private ownership consequently provides no categorical exemption. For the hypothetical sensing company, the absence of a defense contract would not answer whether disclosure creates the relevant security concern. Counsel should explain this possibility without treating every technology with a potential government use as likely to receive an order. Patentability, commercial value, and security sensitivity are separate questions. The USPTO specifically cautions that an order does not establish that the government has adopted the invention or indicate its value. U.S. Patent & Trademark Off., Manual of Patent Examining Procedure § 120(I) (9th ed., rev. 01.2024) [hereinafter MPEP].
A secrecy order also differs from the confidentiality ordinarily afforded an unpublished application. Ordinary application confidentiality governs the USPTO’s release of information; a secrecy order can restrict the applicant’s own disclosures. An applicant’s nonpublication request addresses publication under § 122(b); it neither imposes a secrecy order nor excuses compliance with one. National-security classification presents related but separate handling requirements. These distinctions matter because the appropriate response depends on the legal restriction actually imposed. See 35 U.S.C. §§ 122(a), (b)(2)(B), 181; 37 C.F.R. §§ 5.1(c)–(e), 5.5 (2026).
III Screening and Referral for Agency Review
The USPTO screens applications for sensitive subject matter, including provisional applications and PCT applications filed with the Office. Screening is therefore relevant at the beginning of a filing program, even when substantive examination lies far in the future. The MPEP also directs examiners to flag sensitive information encountered later, including information introduced by amendment. An initial clearance should not be treated as unlimited approval for materially different technical disclosures. MPEP § 115; see also 37 C.F.R. § 5.15 (2026).
According to the USPTO’s current guidance, approximately 98 percent of applications clear review within one to three weeks. Defense-agency referrals can take months. The page describes those reviews as usually taking three to five months, while its table gives five months or more for third-level review. These are approximate descriptions of processing time, not enforceable deadlines or assurances for a particular application. U.S. Patent & Trademark Off., Invention Secrecy—Licensing and Review, supra.
The Patent Center status “Waiting for LR clearance” indicates referral and pending agency responses; it does not itself establish that an order has issued. The USPTO states that it will not transmit the application abroad while awaiting the required responses. It also invites contact with Licensing and Review when a foreign filing deadline approaches or review has exceeded five months. Counsel should identify the actual deadline and requested action when seeking assistance. A general status inquiry may be less useful than explaining that a particular international filing depends on clearance. Id.
IV Reading the Order and Determining Its Reach
The MPEP describes three forms of secrecy order. Type I addresses critical technology with military or space applications and includes permission for foreign filing in specified countries. Type II concerns classified or classifiable information where the application owner has the relevant Department of Defense security agreement. Type III is a general order used where the other types do not apply and may include a permit relaxing specified restrictions. The operative order and its permits must be read together. A reference to its type alone does not establish that a proposed disclosure is authorized. MPEP § 120(I).
The restriction follows the protected subject matter. An application containing a significant part of the subject matter of an application under order also falls within its scope. Pending related applications must promptly be brought to Licensing and Review’s attention unless already under an order, and subsequently filed applications containing that material require the prescribed delivery arrangements. 37 C.F.R. § 5.2(c) (2026). A family review should therefore consider overlapping disclosures, rather than relying exclusively on formal priority relationships. Two applications may describe the same sensitive implementation even when their claims address different aspects of the product.
The same attention is necessary outside the patent portfolio. An investor presentation, engineering drawing, or proposed license agreement may disclose information covered by the order. The company should identify what each recipient needs to receive and compare that proposed communication with the order’s permissions. An NDA can impose contractual confidentiality, but it does not supply government authorization that an order requires. Where permission is needed, the regulations provide a process for seeking a disclosure permit or modification. 37 C.F.R. § 5.5(a)–(b) (2026).
For the sensing company, this analysis could produce different answers for different meetings. A discussion limited to nonsensitive business information may present a different issue from delivery of a detailed technical package. Counsel should define those differences precisely and seek clarification when necessary. A blanket assumption that every activity must cease can unnecessarily damage the business, while an assumption that confidentiality agreements permit technical disclosure can expose it to violations. The governing question remains what the particular order authorizes.
V Continuing Prosecution While Issuance Is Withheld
Unless otherwise ordered, prosecution generally continues. Applications under secrecy order are examined by appropriately cleared examiners under Licensing and Review. The Office converts affected files to paper handling, and counsel must follow the applicable secure correspondence procedures. Ordinary electronic filing and circulation practices should not simply be carried over to the restricted matter. MPEP §§ 115, 121, 130. These handling requirements make it useful to designate responsibility within the prosecution team for receiving correspondence and ensuring timely responses.
A final rejection still requires an appropriate response or appeal to avoid abandonment. An applicant must complete the required appeal steps, although the appeal ordinarily will not be set for hearing until the order is removed. When the application is otherwise in condition for allowance, the Office provides a special notification and suspends the application. That notification is not the conventional notice of allowance under 37 C.F.R. § 1.311. After removal of the order, the Office may issue a notice of allowance or take other warranted action. 37 C.F.R. § 5.3(a), (c) (2026); MPEP § 130.
The practical distinction is consequential: issuance may be blocked while the applicant’s deadlines remain active. Counsel should preserve a functioning docket and avoid assuming that a restriction on disclosure suspends all obligations. Section 181 also permits the Office, on the prescribed agency showing, to maintain an application in a sealed condition when examination itself might jeopardize the national interest. That exceptional procedure reinforces the need to read the actual instructions instead of inferring the application’s procedural status from the existence of an order. 35 U.S.C. § 181.
VI International Protection and Export Authorization
Foreign filing licenses and secrecy orders operate within the same statutory framework but answer different questions. For an invention made in the United States, foreign filing generally requires a license if no corresponding U.S. application has been filed or if fewer than six months have elapsed since the U.S. filing. Filing in the USPTO includes an implicit license request, but counsel must verify that a license was granted and its effective date. There is no mandatory six-month wait when the necessary license has already issued. 35 U.S.C. § 184(a); 37 C.F.R. §§ 5.11(a), 5.12(a) (2026).
The six-month alternative does not override a secrecy order. An application subject to an order cannot be exported or filed abroad except as authorized under the applicable modification or permit procedures. The rules also permit revocation of a foreign filing license and recognize that a secrecy order can displace authorization otherwise arising from the passage of six months. A license covering earlier material should therefore not be treated as permanent approval for every later filing or added disclosure. 37 C.F.R. §§ 5.11(d)–(f), 5.15 (2026).
PCT practice requires distinguishing filing in the United States Receiving Office (RO/US) from transmission abroad. A foreign filing license is not required merely to file a PCT application with the USPTO as receiving office, although authorization may be required before the applicant or the Office forwards the application to the International Bureau or another foreign authority. Applicable handling restrictions remain relevant, and preparation through ePCT may involve an earlier export of technical information. MPEP § 1832; 37 C.F.R. § 5.1(b)(2), (c) (2026).
An international application under secrecy order will not be transmitted to the international authorities. Failure of the record copy to reach the International Bureau in time can result in withdrawal of the international application. Rule 22.3 sets the Article 12(3) period at three months from the date of the International Bureau’s notification to the applicant under Rule 22.1(c) or (g); that trigger is distinct from the ordinary record-copy transmission timetable in Rule 22.1. Regulations Under the Patent Cooperation Treaty rr. 22.1, 22.3. The MPEP identifies a possible means of preserving the U.S. filing date by satisfying 35 U.S.C. § 371(c) before withdrawal when the United States has been designated. Counsel must assess that option in time; it should not be confused with preservation of the entire international filing program. 37 C.F.R. § 5.3(d) (2026); MPEP §§ 120(IV), 1832.
Electronic preparation can raise a separate export issue before filing. The rules extend the scope of a foreign filing license to specified uses of WIPO’s online service for preparing an international application for RO/US. Without that license, users must separately comply with the relevant export regulations before exporting technical data into ePCT. Selecting RO/US as the receiving office does not itself authorize the preceding transfer. 37 C.F.R. § 5.11(b)–(c) (2026); MPEP § 1832.
A USPTO license also does not generally authorize sending invention materials overseas to prepare an application for first filing in the United States. The USPTO has expressly distinguished that activity from the preparation and prosecution of a foreign application. The proper conclusion is that the transfer requires a separate export-control analysis, not that all overseas drafting is categorically prohibited. Nor should patent-related authorization be assumed to cover unrelated research collaboration or commercial technology transfers. Scope of Foreign Filing Licenses, 73 Fed. Reg. 42,781, 42,781 (July 23, 2008); MPEP § 140.
VII Duration and Procedures for Obtaining Relief
An order’s initial duration does not establish when the applicant can expect unrestricted disclosure. Section 181 provides an ordinary one-year period and additional one-year renewals upon an affirmative agency determination of continuing national need. It also contains special duration rules for wartime and presidentially declared national emergencies. An applicant should therefore verify the governing order and subsequent notices rather than assume that a calendar anniversary ends the restriction. The statute authorizes rescission upon the prescribed agency notification that disclosure is no longer detrimental to national security. 35 U.S.C. § 181.
The requested relief should match the applicant’s immediate need. A company seeking to disclose a particular technical feature to a particular recipient may pursue a permit or modification under 37 C.F.R. § 5.5. The petition must explain the purpose of disclosure; foreign-filing requests must identify the countries and intended recipients of the material. For the sensing company, a carefully defined request supporting a specific financing or licensing discussion may be useful even if complete rescission is not presently justified. The request should identify the necessary disclosure and the safeguards the applicant proposes, rather than merely state that the order is inconvenient. 37 C.F.R. § 5.5(b)–(c) (2026).
A petition for rescission under § 5.4 requires facts supporting removal. If existing publications or patents are said to render the order ineffectual, the petition must identify them completely and should include copies. The petition also must address applicable government contracts or state that none exists. An appeal to the Secretary of Commerce follows denial of a rescission petition and must be taken within sixty days of that denial. These procedures provide a route to relief; filing a request does not itself grant the requested permission. 37 C.F.R. §§ 5.4(a)–(d), 5.5(a) (2026).
The MPEP also recognizes possible rescission through expunging sensitive material when that material is unnecessary to an enabling disclosure. This requires coordination with the sponsoring agency. Unilateral deletion of a passage does not establish that the order has ended or that related disclosures are unrestricted. Counsel must evaluate whether the remaining specification adequately supports the intended claims and whether the proposed change actually addresses the agency’s concern. MPEP § 120(V); 35 U.S.C. § 112(a).
Rescission or expiration of a secrecy order does not itself declassify the subject matter or eliminate independently applicable security obligations. Counsel should separately confirm the status of any classification restrictions. A national-security-classified application cannot be published or allowed until it has been declassified and any secrecy order has been rescinded. 37 C.F.R. § 5.1(e) (2026); MPEP § 120(VII).
VIII Compensation and Patent Term Adjustment
Section 183 provides two routes to compensation for damage caused by an order and for qualifying government use resulting from the disclosure. The administrative route requires that the patent be withheld because of the order and that the applicant have been notified that the application is otherwise in condition for allowance. The period for applying to the agency begins with that notification and ends six years after patent issuance. The claim goes to the department or agency that caused the order, rather than the USPTO. If full settlement cannot be reached, the agency may award up to 75 percent of the amount it considers just compensation. The statute permits suit in the Court of Federal Claims or the federal district court where the claimant resides for an amount that, together with any award, constitutes just compensation. 35 U.S.C. § 183; 37 C.F.R. § 5.2(b) (2026).
The direct-action route becomes available after issuance to an owner whose patent application was subject to a secrecy order and who did not apply for administrative compensation under the first route. That action belongs in the Court of Federal Claims. The six-year period described above governs the administrative application; judicial jurisdiction, accrual, and limitations require separate analysis. 35 U.S.C. § 183.
The distinction between the routes was central to Constant v. United States. The Court of Claims declined to import the administrative route’s withholding requirement into the direct-action route and permitted a post-issuance claim even though the order had not delayed issuance. The alleged harm concerned interference with financing and marketing. The court nevertheless emphasized the need for concrete proof rather than speculative damages; its decision allowing the case to proceed was not an award of compensation. 617 F.2d 239, 241–44 (Ct. Cl. 1980).
The later merits outcome illustrates the importance of that qualification. As recounted in Weiss v. United States, Constant ultimately failed to prove actual damages attributable to the order. The record lacked evidence of customers prepared to accept his services or a causal connection to lost business opportunities. 146 F. Supp. 2d 113, 124–25 (D. Mass. 2001) (discussing Constant v. United States, 1 Cl. Ct. 600 (1982)).
That distinction should influence recordkeeping from the outset. A company should preserve evidence explaining why a prospective investor withdrew, what information a potential licensee required, and whether a disclosure restriction prevented a proposed transaction from progressing. A forecast prepared after the fact may be less persuasive than contemporaneous correspondence identifying the specific obstacle. Counsel should also distinguish losses attributable to secrecy from problems involving technical feasibility, market demand, or financing conditions. The strength of the claim will depend on the connection between the restriction and the asserted injury.
Government use presents a separate boundary. In Hornback v. United States, the Federal Circuit held that § 183 does not provide compensation for government use after patent issuance; that use is addressed under 28 U.S.C. § 1498. The court expressly left unresolved whether § 183 reaches use occurring after rescission but before issuance because that interval was not properly before it. The decision should therefore be read according to its holding, without converting it into a categorical rule that compensable use necessarily ends when the order is lifted. 601 F.3d 1382, 1385–87 (Fed. Cir. 2010).
Patent-term adjustment provides a different form of relief for qualifying patents. Section 154(b)(1)(C)(ii) addresses issuance delay attributable to a secrecy order. The implementing rule identifies specific periods, including time in a sealed condition and certain periods associated with a blocked appeal or a determination that the application is otherwise allowable. Calculation also requires attention to overlapping delay, applicant delay, and any terminal disclaimer. Counsel should calculate the adjustment under those provisions rather than assume that every day an order existed will automatically be added to the patent term. 35 U.S.C. § 154(b)(1)(C)(ii), (b)(2); 37 C.F.R. §§ 1.703(d), (f)–(g), 1.704 (2026).
Additional patent term may have substantial value, but it does not recreate a lost market opportunity. If an industrial customer selects a competing platform while the company cannot provide necessary technical details, a later expiration date may not restore the relationship. Compensation and term adjustment address different injuries, and neither should be assumed to substitute fully for timely permission to conduct a commercially necessary activity. For that reason, pursuing a disclosure permit or appropriate modification can be as important as preserving a later monetary claim.
IX Responding to an Order and Preserving Rights
The first response should translate the order into concrete responsibilities. Counsel should identify the sponsoring agency, review all accompanying permissions, establish the authorized handling process, and determine which pending business activities require attention. A portfolio review should identify overlapping disclosures and imminent publications, followed by appropriate contact with Licensing and Review. The company should know who is responsible for prosecution deadlines and who will evaluate proposed external disclosures. These tasks can proceed together; there is no reason to let the patent docket lapse while considering a request for relief. See 37 C.F.R. §§ 5.2(c), 5.3, 5.5 (2026); MPEP § 121.
Counsel should also inventory significant technical disclosures made before the order, including the investor discussions in the opening hypothetical. MPEP § 120(VI) directs prompt notice of the order and improper-disclosure penalties to U.S. citizens in the United States who received significant subject matter or material information relevant to the application. For recipients abroad or foreign nationals in the United States, the principals must not notify those recipients of the order and must instead promptly report the disclosures to Licensing and Review. The report must provide the disclosure date, recipient’s name and address, subject matter, and any U.S. government export authorization, to the extent not already furnished, and identify any relevant foreign application or patent. These directions also cover disclosures made after the order issues. Counsel should determine the applicable response for each disclosure before contacting prior recipients about the order. MPEP § 120(VI).
The consequences of noncompliance arise under distinct provisions. Section 182 permits a holding of abandonment for specified unauthorized disclosures or foreign filings in violation of an order, with forfeiture of claims against the United States based on the invention. Section 185 addresses denial of a U.S. patent and invalidity consequences for foreign filing without the required license. Its invalidity provision includes an exception where the failure to obtain the license occurred through error and the patent does not disclose subject matter within § 181’s scope. Section 186 criminalizes specified willful conduct, including unauthorized disclosure with knowledge of an order, and provides for imprisonment of up to two years. The criminal provision should not be described as imposing strict liability for every administrative mistake. 35 U.S.C. §§ 182, 185–186.
A retroactive foreign filing license is a limited corrective procedure. The applicant must establish the required facts concerning an erroneous unlicensed filing and diligently seek relief after discovery. The required verified statement must also establish that the subject matter was not under a secrecy order when filed abroad and is not currently under one. It does not provide general retroactive permission to disregard an existing order. 37 C.F.R. § 5.25(a)(3), (b) (2026). The practical lesson is to identify precisely what occurred before selecting a remedy. An omitted license, a disclosure beyond a permit’s scope, and a missed prosecution deadline present different legal problems even when they arise in the same matter.
X Improving Administration While Preserving National Security
The secrecy-order framework serves a legitimate security objective, but its administration should account for the decisions applicants must make while an order remains in effect. An applicant may need to know whether it can retain a particular consultant, demonstrate a limited feature, or seek financing without disclosing protected information. Clearer notices identifying the relevant restrictions, the responsible point of contact, and the procedure for requesting permission would make compliance more practical without requiring disclosure of sensitive agency reasoning.
More predictable processing of narrowly defined permit requests would also help. Agencies could establish response targets, identify missing information promptly, and explain whether a proposed disclosure can be narrowed to address the security concern. Review of continuing restrictions should consider changed circumstances and appropriate modifications as well as complete rescission. Where annual renewal requirements apply, the required affirmative determination should provide an occasion to examine continued need. These proposals concern the quality of administration; they do not assume that every delay or renewed order is unjustified.
Compensation procedures deserve similar attention. Congress has recognized that secrecy can impose losses on applicants, yet a right to seek relief after specified milestones may provide limited assistance to a company that needs financing immediately. Greater clarity about the evidence required for a claim and the handling of confidential supporting materials would make the statutory remedy more usable. Policymakers should evaluate how the timing and cost of obtaining relief affect independent inventors and smaller businesses, rather than assume that eventual issuance or additional patent term resolves every injury.
