IP Activity or Publication Trend
What has been the IP publication trend for Carbon Nanotubes?
The patent publication trend in the form of a bar graph shows activity from as early as the 1960’s and 1970’s, although the number of filings remained relatively low all the way up till the year 2000. From 2001 which saw a jump to over 100 patents published, there were huge leaps in the patents published with every year till 2007 which saw more than 880 patents. There has been a slight dip since then but overall, the patents published around carbon nanotubes in energy storage device has remained high and looks to be going strong.
