I find that the distribution of the value of patent rights is highly skewed, that patent protection is a significant but not the major source of private returns to R & D, and that these characteristics vary across technology fields. I compute the R & D cash subsidy that is equivalent to the value of patent rights, measure the variations in value of time, technology fields, and nationalities, and show that these differences are correlated with patent grant rates.
