What is defense tech patents?
Defense tech patents follow the same core patentability requirements as any other patent, novelty, non-obviousness and usefulness, with regulatory overlays layered on top. Export control regimes like ITAR and the EU Dual-Use Regulation can restrict who accesses technical details, and government funding under the Bayh-Dole Act or UK MOD DEFCONs typically grants the government certain use rights.
Same patentability standard, extra regulatory layer
A defense tech patent isn't examined against a different bar than any other patent: it still needs to be novel, non-obvious and useful. What changes is everything around the application, not the application itself. Export control regimes can restrict who's even allowed to see the technical details before filing. Government funding can attach use rights the inventor doesn't otherwise have to negotiate. And in some cases, the government can block publication entirely. None of this is optional or something counsel can advise around after the fact, it needs to be assessed before drafting begins, since it shapes who can work on the application and where it can be filed.
Secrecy orders and foreign filing restrictions
If a US patent office reviewer judges an invention's publication would be detrimental to national security, the USPTO can issue a secrecy order under 35 U.S.C. § 181, withholding the application from publication and blocking the patent from granting for as long as the national interest requires, renewed annually. This isn't a rare, exotic outcome confined to defense contractors: 6,543 orders were active at the end of FY2025 alone, and the USPTO's screening occasionally catches applications from inventors with no government contract at all. Separately, every US inventor, regardless of secrecy order status, faces a 6-month bar on foreign filing under 35 U.S.C. § 184 unless a foreign filing licence is obtained first, a routine approval for most applications but a real deadline to plan around for anything defense-adjacent.
Export controls: ITAR, EAR and dual-use classification
ITAR restricts disclosure of defense-related technical data to foreign persons, which affects not just where an invention can be filed internationally but who's legally allowed to draft or discuss it, including foreign co-inventors or contractors. The EAR covers a broader set of dual-use items with both civilian and military applications. Both are legally separate from a secrecy order: an invention can clear USPTO's national-security screening and still be export-controlled, or vice versa, and each requires its own compliance check. Determining an invention's export control status early shapes both filing strategy and who can legally be in the room while it's drafted.
Government funding and Bayh-Dole rights
Federal funding doesn't cost a contractor patent ownership under the Bayh-Dole Act, but it does attach government use rights, typically a non-exclusive licence, and in limited circumstances, march-in rights allowing the government to require licensing to others if the invention isn't being adequately developed. NIST's December 2023 draft guidance was the first real clarification in years of when march-in rights actually get exercised. SBIR-funded startups face the same underlying framework, and UK and EU equivalents (MOD DEFCONs, Horizon Europe grant conditions) reach similar outcomes through contract terms rather than a single statute, so the specific funding agreement matters more than the general rule.
What most people get wrong
The most common mistake is treating export control and secrecy-order risk as something to check after drafting rather than before disclosure begins: by the time a provisional application is drafted, technical details may already have been shared with foreign co-inventors, contractors, or even the drafting attorney in ways ITAR would have restricted, and that's not something a later filing decision can undo. A second mistake is assuming government funding means losing the patent; it doesn't, but it does mean the funding agreement's specific terms need reviewing before filing, not after a march-in dispute arises.
How Lightbringer handles this
Lightbringer's attorneys factor export control status and government funding terms into filing strategy during the disclosure review, before drafting starts, rather than treating defense tech as a standard filing with extra paperwork bolted on afterward. This includes flagging when ITAR, secrecy order risk, or Bayh-Dole use rights should shape who can be involved in the application before that becomes a problem rather than after.

Frequently asked questions
Defense tech patents protect inventions developed for military, national security or defense-adjacent applications, and they follow the same core patentability requirements as any other patent, novelty, non-obviousness and usefulness, with additional regulatory considerations layered on top. Export control and government funding rules often shape filing strategy more than the underlying patent law does.
Defense technology IP involves the same patent fundamentals as any other field, but adds regulatory overlays like export controls and government funding disclosure requirements that don't apply to purely commercial inventions. Companies working in this space typically need patent counsel familiar with both IP law and defense regulatory compliance.
Military technology patents cover inventions used in defense applications, from hardware and materials to software and autonomous systems, and are examined under the same standards as any other patent. Most jurisdictions can restrict publication of sensitive applications: the USPTO through secrecy orders, the UK under sections 22-23 of the Patents Act (which also require UK residents to get clearance before filing certain inventions abroad first), and Germany through equivalent secrecy provisions in the Patent Act.
Defense startups should understand that government-funded research often comes with government use rights attached to resulting patents, under the Bayh-Dole Act in the US or ministry contract conditions like the UK MOD's DEFCONs, and that export control regimes, ITAR and EAR in the US, the UK Export Control Order, and the EU Dual-Use Regulation, can restrict who can access technical details of certain inventions. Filing strategy should account for these constraints early, ideally with counsel experienced in both patent law and defense contracting.
Dual-use technology has both civilian and military applications, and patenting it follows standard patent law, though export control classification can affect how technical details are shared internationally or with foreign co-inventors. Companies building dual-use technology often need to assess export control status alongside standard patentability.
Dual-use IP strategy involves protecting an invention with both commercial and defense applications in a way that doesn't compromise either market, often meaning careful attention to how technical disclosures interact with export control rules. This is a specialised area where general patent strategy and regulatory compliance intersect.
ITAR (International Traffic in Arms Regulations) is the US regime restricting disclosure of certain defense-related technical data to foreign persons, which affects how and where a covered invention can be patented internationally and who can be involved in drafting or filing it. The UK Export Control Order and the EU Dual-Use Regulation impose analogous restrictions on European companies, and several countries additionally require a foreign filing licence or clearance before sensitive inventions are first filed abroad. Determining an invention's export control status should happen early, since it shapes both the filing strategy and who can legally work on the application.
When an invention is developed with government funding, the government typically retains certain rights, such as a non-exclusive licence to use the invention, even though the inventor or their employer usually still owns the patent: in the US under the Bayh-Dole Act, and in the UK and EU through funding contract terms such as MOD DEFCONs or Horizon Europe grant conditions. These rights need to be understood and disclosed properly when filing.
US Department of Defense intellectual property policy governs how patent rights are handled for inventions developed under DoD contracts and funding, generally following the Bayh-Dole framework that lets contractors retain ownership while the government keeps certain use rights. Other countries take a similar approach through contract terms, such as the UK MOD's standard DEFCON conditions. Specific terms can vary, so reviewing the actual funding agreement is essential.
Yes, drone technology is patented like any other invention, provided it meets novelty, non-obviousness and usefulness requirements, covering everything from flight control systems to specific hardware designs. Drone patents span both commercial and defense applications, and dual-use considerations may apply depending on the specific technology.
Yes, autonomous vehicle technology built for defense use is patentable under standard criteria, though government funding and export control considerations may apply depending on how the technology was developed and its intended use. Specific navigation, sensing or decision-making innovations are the most common patentable elements in this space.
Yes, specific technical methods for detecting, preventing or responding to cyber threats can be patented, provided they go beyond an abstract security concept to a concrete technical implementation. Cybersecurity patents face the same eligibility scrutiny as other software patents, under Section 101 in the US and the technical-character requirement in Europe, so claims need to be anchored to a specific technical mechanism.
Under the US Small Business Innovation Research (SBIR) programme, small businesses generally retain ownership of patents resulting from the funded research, subject to certain government use rights under the Bayh-Dole Act. Similar schemes elsewhere, such as the UK's Defence and Security Accelerator (DASA) or the European Defence Fund, attach their own IP conditions, so understanding the specific grant terms matters for startups relying on this funding.
In the US, under the Bayh-Dole Act, contractors and small businesses can typically retain ownership of inventions developed with federal funding, while the government retains a non-exclusive licence to use the invention and, in limited circumstances, march-in rights. UK and EU funding bodies reach similar outcomes through grant and contract conditions rather than a single statute. The specific terms depend on the funding agreement and should be reviewed carefully before filing.
Yes, but look specifically for firms experienced with the Bayh-Dole Act, which governs patents on inventions made with federal funding. Bayh-Dole lets federal labs, universities and small businesses retain ownership of inventions developed under federal grants or contracts, including SBIR/STTR awards. rather than assigning them to the government, in exchange for compliance obligations like iEdison invention reporting and the government's retained "march-in" rights, which in more than 40 years have never actually been exercised.
A firm that regularly handles SBIR/STTR-funded clients will know the reporting deadlines and the government-use-rights language that needs to appear in the specification. Gaps here don't usually block a grant, but they can create compliance problems later if the invention gets commercialized.
