Do patents of academic funded researchers enjoy a longer life? A study of patent renewal decisions

This paper assesses the extent to which patent renewal data is associated with government funding in a university context by focusing on the relationship between the funded patentees and renewal decisions of their patents. The aim of this paper is to show whether receiving funding from government contributes to high-value patents as measured by the patent renewal decisions made by their owners. Our observations of academic nanotechnology patents in Canada discovered a positive relationship between funded researchers and the rate of patent renewal after 4 years. Further analysis is also undertaken into the relative impact on patent renewal after 8 years and 12 years. Our results suggest that the length of patent renewal in numbers of years can be related to levels of government funding received by their inventors.
