The referenced LED Patent Landscape 26 page report has an interesting Figure 3 ('Technology Evolution Tree of LED Patent Filings') which shows the number of patents filed in each year from 1994 through 2012 by 7 categories (Electronics / Light Management / Heat Management / Light Emissions / Lighting / Displays / Others). 'Light Emissions' is the dominant category while 'Others' is the smallest. Patent filings peaked between 2004 and 2008 and in 2012 were back down to the level of 1994.
