Innovation with and without patents
share
A long-standing discussion is to what extent patents can be used to monitor trends in innovation activity. This study quantifies the amount and quality of information about actual innovation contained in the patent system, based on 4,460 Swedish innovations (1970-2015) that have been matched to international patents. The results show that most innovations were not patented and that among those that were, 43.9 identified with patent quality data. The best-performing models identify 17 all information about innovations, equivalent to an information loss of at least 83 responding to strengthened patent laws during the period were on average 8 percent. The overlap between the patent and innovation systems is hence more modest than often assumed. This accentuates the need to, alongside patents, develop versatile approaches in order to induce and monitor various aspects of innovation.
