In 2012, the USPTO published 4,098 nanotechnology class 977 applications, which represents a 19.2% increase over last year.
By way of comparison, in 2008, the USPTO published only 827 nanotechnology applications, and in 2009, only 1,499.
Hence, the number has almost tripled in three years.
This patenting trend is consistent, as we have previously commented in our November 25, September 4, and July 8, 2012 posts.
Hopefully, federal policy makers are noticing this important trend and managing well the implications including licensing and litigation. At least 12.4% of the filings report a federal funding statement as required under the Bayh-Dole act.
