Patent activity (1983 to 2008)

Research related to the development and fabrication of inorganic nano structural composites has been in progress since 1983. However, patent activity in this area increased after 2002 and as of today, a large number of patent and non-patent publications are available.Application areas for inorganic nanostructural composites include washing machines, optics, magnetic recording medium, oxygen reduction electrode, Carbon nanotubes, quantum dots, biolabelling etc. In this patent tracker, SciTech brings out an overview of patents published on inorganic nano structural composites. Our patent search, based on class codes pertaining to inorganic nanostructures including fullerene-type cage structures and metalloids has identified top patent filers,universities,independent inventors as well as possible research collaborations in this area. The period of study is 1983 to 2008.
