For the past several years, the McDermott Will & Emery Nanotechnology Group has investigated trends in nanotechnology patent literature as a means of identifying research trends, pinpointing industry leaders, and clarifying the importance of the United States in this technology revolution. We offer this 2014 Special Report as a continuing study of trends observed in our 2013 and 2012 reports, and also present a renewed focus on trends in the energy sector.
Carbon takes these nanoparticle forms.
In 2013, the trends observed for nanotechnology patent literature included the following highlights:
The total volume of published nanotechnology patent literature increased 5% in 2013 and has more than tripled since 2003.
The number of U.S. patents issued in nanotechnology was more than 6,000 in 2013, a 17% increase over 2012.
About 54% of the nanotechnology patent literature published in 2013 was assigned to U.S.-based entities, followed by South Korea at 8.3%, Japan at 8.0% and Germany at 5.8%.
The top-three assignees of the nanotechnology patent literature published in 2013 are primarily in the Computers and Electronics sector. The other two assignees rounding out the top five are universities in China and the United States.
The nanotechnology patent literature in the Energy sector increased 8% in 2013.
The McDermott team also performed a more detailed analysis of the innovation trends in graphitic carbon-based nanotechnology innovations. Graphitic carbon-based nanoparticles (fullerenes, carbon nanotubes and graphene) have unique structures that give rise to interesting electrical, spectral, thermal and mechanical properties that can be exploited in applications across many technology sectors. While some of the same trends were seen when comparing graphitic carbon-based nanotechnology innovation to nanotechnology innovation in general, some surprising observations were made with respect to graphitic carbon-based nanotechnology innovation including the following:
While 50% of the graphitic carbon-based nanotechnology patent literature published in 2013 was assigned to U.S.-based entities, Eastern Asia’s market share is about 37%, which is 9% more than for nanotechnology patent literature in general.
While the United States has at least one of the top three assignees in each of the six technology sectors analyzed, Eastern Asia-based companies are more prevalent players in graphitic carbon-based nanoparticles as compared to nanotechnology innovation in general.
The Energy sector is also the fastest-growing sector for graphitic carbon-based nanotechnology innovation, with an 18% increase in 2013.
