Knowledge Production in Technological Innovation System: A Comprehensive Evaluation using a Multi-criteria Framework based on Patent Data - A Case Study on Hydrogen Storage

Abstract

Knowledge production activity is central within a technological innovation system. The number of patent ap plications is commonly used to evaluate this activity. However, it is subject to bias and inaccurate evaluations can occur. This article proposes a multi-criteria framework based on seven complementary patent indicators, taking into account the persistence, commitment, and coherence of knowledge production activities for a more comprehensive evaluation. We demonstrate the value of our proposal through a case study on hydrogen storage, comparing patent data since 2000 about three technological solutions: physical, chemical and adsorption technologies. Our framework clearly shows that physical hydrogen storage is the most advanced in terms of knowledge production, despite not having the highest number of patent applications.
