International Patent Law and Jurisdiction in Outer Space

Syllabus: International institutions, agreements and conventions

Context and Emerging Challenge

  • Sustained human presence in space demands continuous technological innovation for survival systems and infrastructure.
  • Multinational crews collaborate across shared habitats, platforms, and digital systems in extraterrestrial environments.
  • Innovation increasingly occurs beyond Earth’s sovereign boundaries, raising unresolved questions of legal ownership.

Territorial Basis of Patent Law

  • Patent systems operate on territoriality, granting exclusive rights within defined national jurisdictions.
  • Authorities determine infringement by locating where making, using, or selling occurred.
  • This logic functions on Earth due to clear geographic boundaries and singular legal authority.

Outer Space Legal Framework

  • International law prohibits national sovereignty over celestial bodies, including the Moon and Mars.
  • Article VIII of the Outer Space Treaty links jurisdiction to the state of registry of space objects.
  • The Registration Convention reinforces legal control by registry, not by physical location.

Jurisdiction-by-Registration Model

  • Innovations aboard registered space objects are treated as occurring within the registering state’s territory.
  • This model extends domestic patent laws into space through administrative registration choices.
  • The approach functions in static, segmented environments, such as the International Space Station.

International Space Station Example

  • ISS modules are allocated jurisdiction partner state by partner state under Article 21.
  • Each module is treated as national legal territory for intellectual property purposes.
  • This system relies on stable structures and clearly identifiable national zones.

Limits in Permanent Space Settlements

  • Lunar and planetary bases involve shared infrastructure, remote software updates, and multinational operations.
  • Innovations emerge through incremental, collaborative refinements rather than isolated acts.
  • Determining where invention legally occurs becomes unclear and contested.

Non-Appropriation and Exclusivity Tension

  • Article I of the Outer Space Treaty frames space as benefiting all humankind.
  • Article II prohibits national appropriation of celestial bodies.
  • Patents may create de facto exclusion over survival-critical technologies, challenging this principle.

Temporary Presence and Enforcement Gaps

  • Article 5 of the Paris Convention limits patent enforcement for transiting patented articles.
  • Its applicability to space platforms, docking stations, or registered objects remains undefined.
  • Legal uncertainty enables regulatory arbitrage through selective registration strategies.

Global Governance and Institutional Response

  • Over 110 states are treaty members, but few shape practical jurisdictional interpretations.
  • Artemis Accords provide coordination mechanisms, not binding legal authority on ownership.
  • Calls for specialised space intellectual property frameworks are growing but remain fragmented.
