There are no current estimates of the average number of transactions per patent. Some patents, such as those participating in some patent pools, may be licensed several thousand times. However, exclusive licenses are still very common and patent sales typically do not occur annually. A range of say 1 to 5 transactions per patent is a reasonable guess.
Likewise, with so much rough estimation of other necessary numbers, no reasonable estimates of the magnitudes of spillovers is available. Innovation has strong positive externalities so the spillover factor should therefore be greater than 1. Moreover, innovation is an input into many different types of economic activity, including more innovation. This would suggest that, at least for the purposes of GDP accounting, the multiplier should be more than 2: The seller would experience the revenue from the license and the buyer would experience new revenue from the sale of a product or new innovation for which the input was necessary.

'''Griliches Excerpt:'''
"Among the patents reported to be in current use and with relevant numerical responses and a positive gain (accounting for about 20 percent of all the relevant responses), the mean value was $577,000 per patent, but the median value was only about $25,000 (implying, under the assumption of log normality, 2.5 as the coefficient of variation and a standard deviation of about $1.5 million). If one includes all the no gain, loss, and not yet used patents, the mean gain falls to about $11 2,000, and the median is close to zero or below (computed from the tables in Sanders, Rossman, and Hams 1958, pp. 355 and 357). Even this lower mean number is quite impressive, roughly equivalent to $473,000 per average patent in 1988 prices (using the GNP deflator to convert it from 1957 prices), but so also is the associated dispersion."
