Features of Sustainability-Oriented Innovations: A Content Analysis of Patent Abstracts

Abstract

This article aims to identify the features of sustainability-oriented innovation starting from the content analysis of patent abstracts. An automatic tool was developed capable of finding the keywords, or groups of keywords, related to the 169 targets of sustainable development goals (SDGs). Once the patents deemed useful for pursuing SDGs were selected through the tool, they were analyzed to obtain information on their features in terms of breadth, scope, novelty, openness, prior art and scientific base. Among the most significant results, it is found that a larger number of applicants, suggesting the adoption of “open innovation” strategies, contributes to sustainability orientation. Moreover, patent originality contributes to the probability of pursuing sustainable objectives, especially related to environmental issues. On the contrary, claims are inversely correlated with the attitude to pursue SDGs, i.e., the larger number of areas in which a patent claims to intervene, the lower the probability that such innovation is sustainable. The results obtained by adopting a quantitative approach are in line with suggestions proposed by the literature and, so far, only supported by logical arguments or case studies. The potential of the tool developed, applied to the field of innovation and sustainability, is demonstrated as significant.
