What Is Nanotechnology?

Modern nanotechnology is applied from either a top-down or bottom up approach. The former involves making structures smaller and smaller, and the latter involves assembling matter or building a mechanism from scratch on the nanoscale.

Though this technology is new, its applications are wide reaching. Nanoscience and nanotechnology have applications across all scientific fields and is currently impacting the following industries:

  • Health care: Nanoscale diagnostic tools can be used to treat patients at the cellular level. Moreover, nanomedicine is at the forefront of advances in the detection and treatment of cancer and heart disease.
  • Electronics: Microscopic electronic components allow for the development of more powerful and more compact hardware.
  • Aerospace: Nano materials can be used to create lighter, stronger, thinner materials for use in aircraft and spacecraft.
  • Conservation: Nanotechnology may advance the production and efficiency of solar energy panels and other alternative energies. Researchers are also experimenting with metal nanoparticles to make water potable in rural and underdeveloped parts of the world. Nanoparticles are also being used to convert the nitrogen oxide in concrete, making this material less harmful.

Emerging Trends in Nanotechnology Development

Nanotechnology is advancing rapidly, transforming industries beyond electronics and healthcare. Researchers are now focusing on sustainable applications, including nanomaterials for environmental remediation, energy-efficient systems, and enhanced agricultural productivity​. With growing concerns about sustainability and climate change, nano-enabled green technologies are gaining significant attention.

In medicine, the trend toward "smart" nanomedicine is noteworthy, with targeted drug delivery systems and nanosensors capable of detecting diseases at earlier stages. Meanwhile, in computing, nanotechnology is propelling quantum computing and ultra-efficient microprocessors, opening new horizons for artificial intelligence and big data​.

Patents in the Nanotechnology Industry

Filing patents related to nanotechnology isn't as straightforward as filing patents for other types of inventions. A few issues related to filing patents for nanotechnology are listed below.

  • Nanotechnology is an emerging field, and patents for broad processes or products would limit the advancement of innovation. Since this technology is still young, patents for similar general ideas can easily flood the marketplace.
  • Simply reproducing a product or process at the nanoscale will not distinguish the invention as “new," and therefore, will not be patentable.
  • If nanotechnology is applied just to make a product or process function at the nanoscale, the patent holder of the original invention may be entitled to royalties.

According to StatNano, about 50 percent of the patents filed are from U.S. companies. The other half mostly come from South Korea, Japan, and Taiwan. As of 2016, the U.S. Patent and Trademarks office has published approximately 20,000 nanotechnology patents and the European Patent Office has published roughly 4,000.

Though filing a nanotechnology patent presents unique challenges and consideration, they do exist for inventions across dozens of industries. Nanotechnology inventors are racing to discover new products and processes and file patents for inventions in aerospace, medicine, energy, automotive, and virtually all other fields.

However, most patents filed are related to computers and electronics. Companies like IBM, Samsung, and Xerox have filed multiple patents for nanotechnology, as have educational institutions such as University of California and MIT. Companies in fields such as chemistry and biological sciences are also eager to bring nanotechnology products to market. Such inventions could revolutionize medicine and agriculture, promising huge financial rewards for these trailblazing researchers.

A study from the McDermott Will & Emery Nanotechnology Affinity Group has reported a few trends regarding nanotechnology patents:

  • The number of published nanotechnology patents worldwide has more than tripled since 2003.
  • The number of published nanotechnology patents in the U.S. exceeded 6,000 in 2013.
  • Nanotechnology innovation is surging; there was a 17 percent increase in the number of nanotechnology patents published in 2013 compared to the year before.

McDermott Will & Emery Nanotechnology Affinity Group also reported major growth in the following sectors since the early 2000s: computers and electronics, chemistry, biological sciences, materials, metrology and instrumentation, and energy.

These results reveal that nanotechnology innovation is a priority for many companies and that there is a serious commercial interest in improving virtually all processes and products that we use today. This study and other materials from the McDermott Will & Emery Nanotechnology Affinity Group are excellent resources for nanotechnology research and better understanding the legal matters related to this science.

Global Growth and Leading Players in Nanotechnology IP

The global landscape of nanotechnology IP is highly dynamic:

  • Leading Nations: The United States, South Korea, Japan, and China are at the forefront of nanotechnology patent filings​.
  • Top Corporations: Multinational companies like IBM, Samsung, Intel, and BASF dominate nanotech patent portfolios, focusing heavily on semiconductors, biotechnology, and new materials.
  • Academic Contributions: Universities such as MIT, Stanford, and the University of California have significantly boosted innovation through patented research initiatives​.

Patent filings in the sector have increased steadily over the past decade, reflecting intensified competition and commercial interest across multiple industries​.

Key Legal Challenges in Nanotechnology Patents

Despite the surge in innovation, nanotechnology patents face distinct legal hurdles:

  • Defining Inventions at the Nanoscale: Since size alone doesn't guarantee patentability, inventions must exhibit new functions or improved properties due to nanoscale manipulation​.
  • Overlapping Claims: The broad and interdisciplinary nature of nanotechnology often leads to overlapping patent claims, complicating patent clearance and increasing litigation risks.
  • Territoriality Issues: Patents are jurisdiction-specific, but nanotech innovations frequently have global implications. Filing across multiple regions is expensive and complex​.
  • Meeting Non-Obviousness Standards: Many nanoscale inventions are refinements of existing technologies, raising challenges in meeting the non-obviousness requirement under IP law.

Addressing these challenges often requires robust patent drafting strategies, cross-disciplinary expertise, and careful navigation of existing patents in adjacent fields​​.

Patent Offices Around the World

USPTO and EPO are two primary offices that process patents for nanotechnology inventions worldwide.

International Initiatives for Nanotechnology IP Harmonization

Recognizing the challenges unique to nanotechnology IP, international bodies like the World Intellectual Property Organization (WIPO) are exploring ways to standardize patent criteria​. The European Patent Office (EPO) and the U.S. Patent and Trademark Office (USPTO) have also published specific guidelines on how nanotechnology patents are assessed for novelty, inventive step, and industrial applicability.

Key initiatives include:

  • Developing standardized definitions for nanotechnology across jurisdictions.
  • Encouraging clearer disclosures in patent applications to avoid ambiguity.
  • Promoting cross-border cooperation to manage overlapping patent rights​.

These measures aim to foster innovation while balancing the rights of inventors and the broader public interest.
