The 2012 Fuel Cell Patent Review is the second in Fuel Cell Today's series of reports on fuel cell patent activity. It analyses both granted patents and patent applications published in 2011, by comparison with publications in 2010.
The number of granted fuel cell patents increased by 51% between 2010 and 2011, a significantly higher increase than that for overall granted patents worldwide.
Fuel cell patent applications also continue to grow, with a 58% increase in 2011 versus 2010. This was also considerably more growth than was seen for total worldwide applications
The emergence of Asia as a dominant patenting force has also been identified, with the World Intellectual Property Organization observing double-digit growth in applications from Japan and China. Fuel Cell Today has tracked the emergence of China as a named country in the fuel cell patent literature and this is discussed in the 2012 Review.
