Exploring the invisible gold rush at the atomic scale where trillions of dollars are at stake in the race to control matter itself.
Imagine a world where the cure for cancer is delivered directly to diseased cells by microscopic particles, where materials repair themselves at the molecular level, and where computers are thousands of times more powerful than today's best machines. This isn't science fiction—it's the promise of nanotechnology, the science of manipulating matter at the atomic and molecular scale. But as researchers push the boundaries of what's possible at the nanoscale, a critical question emerges: who owns the atoms?
In the race to control this microscopic frontier, intellectual property (IP) has become the new battlefield. With the global nanotechnology market projected to reach trillions of dollars, corporations, universities, and governments are scrambling to secure their piece of the nanopie.
This article explores the fascinating, complex world of nanotechnology IP—where the stakes are enormous, the science is revolutionary, and the legal battles are anything but small.
Nanotechnology involves designing, producing, and applying materials and devices at the molecular scale—typically between 1 and 100 nanometers. To appreciate this scale, consider that a single nanometer is about 40,000 times smaller than the width of a human hair, and each nanometer spans only three to five atoms wide .
At this incredibly small scale, the ordinary rules of physics begin to break down, and quantum effects take over. Materials can exhibit surprising new properties—changing color, becoming stronger, conducting electricity better, or reacting chemically in ways impossible at larger scales.

In the high-stakes world of nanotechnology research and development, patent protection has become essential. Unlike trade secrets—which can be difficult to maintain for products that can be reverse-engineered—patents provide 20 years of exclusive rights to make, use, or sell an invention 8 .
This exclusivity is crucial for recouping the substantial investments required for nanotechnology research and development.
The statistics tell the story of a field exploding with activity: nanotechnology patent applications grew more than 50-fold between 1991 and 2008 , with China and the U.S. now dominating global filings.
In 2018 alone, approximately 3.3 million patent applications were filed worldwide, with Asia emerging as the region filing more than half of all applications for the first time 6 .
This rush to patent has been described as an "IP gold rush" 8 , with early movers seeking "blocking patents" on essential technologies that could give them leverage over later developments. Companies that delay seeking protection risk being shut out of markets or having to pay significant licensing fees to those who filed first.
The frenetic pace of nanotechnology patenting has created what experts call a "patent thicket"—a dense web of overlapping intellectual property rights that makes it difficult to commercialize new technologies without infringing on someone else's patents 6 .
This thicket is particularly dense in nanotechnology because:
One surprising challenge in nanotechnology patenting is the lack of a standardized definition of what constitutes "nanoscale." Different patent offices have adopted slightly different definitions, generally restricting nanotechnology inventions to a length scale of less than 100 nanometers .
This inconsistency creates problems:
This problem is compounded by what's known as the "IP divide"—a significant gap between high-income countries that file the majority of nanotechnology patents and middle- and low-income countries that are largely left out of the patent race 6 .
A fundamental principle of patent law is that inventions must be novel and non-obvious 8 . But when it comes to nanotechnology, what counts as truly new? Many nanotechnology inventions involve nanoscale versions of previously known materials or structures.
If a material was known at larger scales, does creating a nanoscale version deserve patent protection?
The key question becomes: would creating the nanoscale version have been obvious to a person skilled in the field?
Nanotechnology is inherently interdisciplinary, spanning physics, chemistry, materials science, biology, and engineering. This creates unique challenges for patent examiners, who typically specialize in specific technical fields.
When a single nanotechnology patent application spans multiple scientific disciplines, it's unlikely any single examiner has all the necessary expertise to properly evaluate it .
This multidisciplinary nature heightens the risk that relevant prior art might be overlooked, potentially resulting in patents being granted that shouldn't be.
Patent offices are addressing this through specialized training and the development of nanotechnology-specific classification systems like the USPTO's "Class 977" .
One landmark case that illustrates the novelty question in nanotechnology patents involved chemical giants BASF and Orica Australia . The dispute centered on polymer nanoparticles and whether Orica's invention was truly novel compared to BASF's earlier patent.
Orica's researchers had developed polymer nanoparticles smaller than 100 nanometers that exhibited remarkably improved technical properties, resulting in a glossier coating compared to the larger particles protected under BASF's prior patent.
The key question before the European Patent Office's Technical Board of Appeals was whether this size difference—and the resulting property improvement—was enough to establish novelty.
The research team approached this challenge through a systematic process:
| Material/Reagent | Function in Experiment | Significance |
|---|---|---|
| Polymer Precursors | Base material for nanoparticle synthesis | Controlled composition allowed consistent reproduction |
| Emulsifiers | Stabilized nanoparticle formation | Prevented aggregation during synthesis |
| Size Characterization Tools | Measured exact nanoparticle dimensions | Provided critical patent evidence |
| Optical Measurement Devices | Quantified gloss and clarity | Demonstrated unexpected advantages |
The European Patent Office's Technical Board of Appeals ruled in Orica's favor, determining that the smaller particles exhibited remarkably improved technical properties that resulted in a practically superior product.
The decision established that:
This case set an important precedent for how size-related property changes can establish patentability in nanotechnology, even when the base material was previously known.
| Particle Size Range (nm) | Surface Gloss | Coating Durability | Production Consistency |
|---|---|---|---|
| >150 nm | Moderate | Good | High |
| 100-150 nm | Good | Good | High |
| <100 nm (Orica) | Excellent | Very Good | Moderate |

The question of "who owns the atoms" lies at the heart of nanotechnology's future. As we've seen, the answer is complex, contested, and constantly evolving. The race to control nanotechnology through intellectual property reflects its enormous potential to transform industries, treat diseases, and address global challenges.
Yet important questions remain about how to balance the legitimate interests of inventors with the need for equitable access to nanotechnology's benefits. How do we prevent the "patent thicket" from stifling the very innovation it's meant to protect? How can we ensure that nanotechnology's benefits reach beyond wealthy nations and corporations to address global needs?
The answers to these questions will shape not just who profits from nanotechnology, but who benefits from its revolutionary potential. In the end, the story of nanotechnology IP is still being written—atom by atom, patent by patent, and innovation by innovation. What remains clear is that in the invisible realm of the nanoscale, the stakes have never been larger.
