    Patents are rich sources of technical and commercial information. Bibliometric analysis of patents provides information on the nature and growth of the inventive activity; its international comparison; the active players from industry, academia and government; co-inventorship; linkages with science; and technological trends. The present paper highlights the results of such a study in the area of carbon nanotubes. The analysis indicates that first patents were filed immediately after the discovery of the carbon nanotubes. The researchers at Nippon Electric Company (NEC) have been most active in the field. There is considerable thrust on patenting in the area of synthesis or processes for production of the carbon nanotubes. The technological trends indicate the possibilities of applications in the areas of nano test tubes, nanoelectronics, and polymer and composite materials.
