Canadian data show that the 25 largest Canadian R&D firms performed 33% of all domestic industrial R&D in 2009 (Statistics Canada, 2010). Likewise, in 2008 the top ten patenting firms filed about 8% of international patents (Patent Cooperation Treaty, PCT) and the top 20 filed 12%. Patenting is similarly concentrated in major areas such as the People’s Republic of China, Europe, Japan and the United States (WIPO, 2008).
