The 2004 OSRM Study
In 2004, Open Source Risk Management commissioned a patent study, carried out by Dan Ravicher. For this study, Ravicher performed patent searches to estimate the patent-risk of the Linux kernel:

Famous quotes containing the word study:
“Surely the one thing needful for a Christian and an Englishman to study is Christian and moral and political philosophy, and then we should see our way a little more clearly without falling into Judaism, or Toryism, or Jacobinism, or any other ism whatever.”
—Thomas Arnold (1795–1842)
