The UK space sector has been experiencing robust growth, averaging a 3.3% annual increase in real terms since 2009/10, according to the UK Space Agency's Size and Health of the UK Space Industry 2024 report. This expansion is fueled by both private companies and scientific endeavors, highlighting the urgent need for a legal framework that can adequately protect intellectual property rights (IPRs) in outer space.
Despite the increasing use of patented inventions, trademarks, and copyrightable works in space, there are currently no international laws, treaties, or conventions that explicitly address the protection and enforcement of these rights in the extraterrestrial context. The absence of such rules leaves significant gaps for companies and innovators seeking to safeguard their intellectual assets as commercial activity in space accelerates.
Patents, which protect new inventions, are inherently territorial and must be registered in specific jurisdictions. They grant the owner the right to prevent others from making, using, or selling the invention within the registered territory for a limited period, in exchange for public disclosure of the invention. Patented products and processes are already being used in outer space, and the potential for new inventions originating in this environment is expected to grow.
Trademarks, which serve as badges of origin, are also territorial rights. They can take many forms, including words, slogans, logos, shapes, colors, and sounds, and are used to distinguish the goods or services of one entity from another. In the context of space tourism, major commercial players such as SpaceX, Blue Origin, and Virgin Galactic are expected to utilize trademarks to protect their branding both on Earth and in space, potentially extending to branded experiences aboard spacecraft and space stations.
Copyright protects original works of certain types, including literary, dramatic, musical, and artistic works (LDMA Works). Copyright arises automatically upon creation and provides the owner with exclusive rights to reproduce and publish the work. While copyright is territorial, international agreements often extend protection to works created in one country across multiple jurisdictions. Copyrightable works are already being created and used in outer space, including photographs, drawings, films, broadcasts, music, scientific records, and databases. With high-profile figures such as popstar Katy Perry participating in space missions, the prospect of new creative works originating from space is becoming a reality.
The territorial nature of IPRs raises critical questions about their applicability in outer space. Key issues include whether Earth-based IPRs extend to acts committed in space, how infringement is determined, and which countries have jurisdiction to adjudicate such claims. For example, it is unclear whether the use of a trademark in outer space counts toward genuine use of the corresponding Earth registration, or whether acts committed in space can constitute infringement of an Earth IPR.
Another area of uncertainty is the protection of IPRs created in outer space. It remains to be seen whether such rights are automatically protected on Earth and whether any special rules or conditions apply to their registration or enforcement.
Given the territorial basis of most IPRs, it is important to distinguish between activities conducted in outer space and those related to space but occurring on Earth, as the legal treatment of these activities depends on whether they fall within the jurisdiction of a particular country or are considered to have taken place in the international domain of outer space.
A fundamental question in this context is the definition of outer space itself. Scientifically, there is no precise boundary marking the end of Earth's atmosphere and the beginning of outer space, as the atmosphere gradually thins with altitude. The Kármán line, set at 100 kilometers (about 62 miles) above sea level, is often cited as the threshold, but this is not universally accepted. The absence of a clear legal definition complicates the determination of jurisdiction and the application of terrestrial laws to space activities.
Despite these challenges, some existing legal instruments provide a starting point for addressing IP issues in space. The Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (the Outer Space Treaty), establishes that outer space is not subject to national appropriation. However, Article 8 of the Treaty grants the state of registration of a space object jurisdiction and control over that object and its personnel, suggesting a possible mechanism for extending IPR protection to space-based activities.
As commercial and scientific use of outer space continues to expand, the development of a comprehensive international legal framework for intellectual property rights in this new frontier remains an urgent priority.
