The Jurisdictional Fiction: Extending Territoriality Beyond the Kármán Line
Intellectual property law is fundamentally territorial. Patents are granted, enforced, and limited by national borders. Space activity, however, takes place in a domain where territorial sovereignty is expressly prohibited. This tension has produced what practitioners often describe as a “jurisdictional fiction,” under which space objects are treated as extensions of national legal systems for limited purposes, including IP enforcement.
As commercial activity expands in Low Earth Orbit (LEO), geostationary orbit, and cislunar space, SpaceTech companies must navigate a legal environment where jurisdiction is decoupled from geography and instead anchored to registration, control, and nationality.
Article VIII of the Outer Space Treaty (OST) and the Registry State Principle
The cornerstone of jurisdiction in outer space is Article VIII of the Outer Space Treaty, 1967. It provides that a State Party on whose registry a space object is carried retains jurisdiction and control over that object and over personnel aboard it.
This principle is operationalized through the Registration Convention, 1975, which requires every space object to be registered by a launching state and notified to the United Nations. In practice, registration establishes the legal nexus through which national laws, including patent law, attach to activities in orbit.
From an IP perspective, this produces a default rule. In the absence of a dedicated international IP treaty for space, the law of the registry state governs acts occurring on board that space object. If a satellite is registered in India, the Indian Patents Act, 1970 is the primary statute for assessing infringement, subject to conflicts rules and contractual allocations.
Quasi-Territoriality: How 35 U.S.C. § 105 Defines “United States” in Orbit
The United States is the only major jurisdiction that has codified this jurisdictional fiction expressly in its patent statute. Under 35 U.S.C. § 105, any invention made, used, or sold on a space object under the jurisdiction or control of the United States is deemed to have occurred within the United States for patent purposes.
This provision has two critical implications. First, it eliminates uncertainty for US-registered spacecraft by statutorily extending US patent law into orbit. Second, it introduces strategic registry considerations. The statute does not apply where the space object is carried on the registry of a foreign state.
As a result, the choice of registry is not merely a regulatory decision. It directly affects patent enforceability. For SpaceTech founders and in-house counsel, registry selection must be evaluated alongside filing strategy, enforcement risk, and licensing leverage.
The Indian Space Policy 2023: Emerging Frameworks for NGEs and IP Ownership
India’s Space Policy 2023 marks a structural shift from a state-dominated model to one that actively enables Non-Governmental Entities (NGEs). It recognizes private ownership and operation of space objects and establishes IN-SPACe as the authorizing and supervisory body for private space activity.
While India does not yet have a space-specific IP statute, the policy clarifies that NGEs may own and exploit IP generated through self-funded missions, subject to national security, export control, and international treaty obligations. Earlier drafts of the Space Activities Bill contemplated broader state ownership for government-funded missions. Based on publicly available guidance and current 2026 practice, IN-SPACe generally permits private IP ownership where public funding or strategic assets are not involved.
For SpaceTech companies, this creates a workable but incomplete framework. Patent strategy must anticipate future statutory developments while operating within existing patent, security, and authorization regimes.
Patent Prosecution for Extra-Terrestrial Inventions
Patent prosecution for space-related inventions raises challenges that are uncommon in terrestrial technologies. These challenges arise from enablement requirements, proof of inventive step, and the physical impossibility of inspection or replication on Earth.
Disclosure Requirements for In-Space Manufacturing and Microgravity R&D
Microgravity-enabled inventions, including advanced materials, pharmaceuticals, and biological structures, often exhibit properties that cannot be reproduced under terrestrial conditions. Patent law nevertheless requires full and sufficient disclosure.
To satisfy enablement and sufficiency requirements, specifications should describe the orbital conditions under which the invention operates. This may include altitude ranges, microgravity thresholds, radiation exposure, thermal cycling, and mission duration.
Where possible, comparative data demonstrating technical effects unique to space conditions strengthens inventive step arguments. Examiners are more likely to accept claims where the advantage is framed as a technical improvement rather than an abstract benefit of being in orbit.
Strategic Claim Drafting: Capturing “Earth-Side” Infringement for Orbital Assets
Direct enforcement against acts occurring in orbit is procedurally complex and evidentially burdensome. A more reliable strategy is to draft claims that capture infringement at terrestrial control points.
Effective approaches include claiming systems configured for orbital deployment, ground control segments, communication architectures, and pre-launch integration steps. By anchoring infringement to Earth-based activities, patentees can enforce rights in domestic courts without proving physical acts in space.
Distributed system claims are particularly valuable. Where command, control, and data processing occur on Earth, infringement can often be established even if the payload operates in orbit.
Checklist: Drafting to Avoid the “Flag of Convenience” Loophole
The “flag of convenience” risk arises when competitors attempt to avoid patent exposure by manufacturing in non-protective jurisdictions and registering space objects in states with weaker enforcement.
To mitigate this risk:
· Draft system claims that include terrestrial components.
· Include product-by-process claims where space-manufactured products return to Earth.
· Capture ground station operations and pre-launch configuration steps.
· Avoid claims limited solely to in-orbit performance.
Enforcement and Liability in a Sovereignless Domain
Outer space is not subject to sovereignty, but it is not lawless. Enforcement relies on a combination of national law, contractual governance, and international responsibility principles.
The Doctrine of Temporary Presence (Section 49 and 35 U.S.C. § 272)
Both Indian and US patent law recognize a doctrine of temporary presence, which exempts foreign vessels from infringement when their presence is incidental or transitory.
In India, this is codified in Section 49 of the Patents Act, 1970. In the United States, a parallel exemption exists under 35 U.S.C. § 272.
In the context of space launch, this doctrine typically protects launch vehicles passing through airspace. However, it is less likely to shield payloads intended for long-term operation that provide commercial services connected to the territory.
Proving Infringement on Non-National Space Objects: Evidentiary Hurdles
Physical inspection of satellites is impractical. Infringement must therefore be inferred through indirect evidence such as telemetry, signal analysis, orbital behavior, and public regulatory filings.
In response, SpaceTech licensing and collaboration agreements increasingly include audit rights, software escrow mechanisms, and telemetry access clauses. These contractual tools often provide more practical enforcement leverage than litigation alone.
Collaborative Projects: IP Governance in the ISS IGA and Future Moon-to-Mars Frameworks
The ISS Intergovernmental Agreement provides a model for IP governance in multinational missions. Under Article 21, inventions are deemed made in the territory of the partner state that provided the module where the invention occurred.
Future frameworks under the Artemis Accords and planned lunar gateways are moving toward mission-specific IP allocation. Jurisdiction, ownership, and licensing are increasingly addressed ex ante rather than litigated ex post.
SpaceTech IP Valuation and Strategic Filing
SpaceTech IP portfolios are capital intensive and strategically sensitive. Their valuation depends not only on technical merit but on jurisdictional positioning and enforceability.
The PCT Route for Orbital Assets: Timing the Entry into Space-Faring Jurisdictions
The Patent Cooperation Treaty is the preferred route for SpaceTech filings due to long development cycles and high costs. National phase entry should be prioritized in launching states, manufacturing hubs, and control jurisdictions.
Patents granted in jurisdictions with high launch frequency or regulatory choke points carry disproportionate strategic value.
Impact of National Security Reviews on Global SpaceTech Filing Strategies
Space technologies are often dual-use. Foreign filing licenses are mandatory in many jurisdictions, including India and the United States, before filing abroad.
Failure to obtain clearance can invalidate patents and expose applicants to penalties. Filing strategies must therefore integrate export control and security review timelines from the outset.
