“…The level of uncertainty is very high and codification is low, as partners work on concepts that are still to be defined in detail and that can be significantly changed along the process. As a consequence, legal mechanisms, especially patents, can seldom be used (Hussinger, 2006;Bader, 2008;de Faria and Sofka, 2010;Bogers, 2011), or can be used but at low quality level, as the fuzzy nature of innovation prevents companies from having well-written and wellgrounded patents that are able to avoid 'invent arounds' (Teece and Pisano, 2007;Somaya et al, 2011). Furthermore, several different types of partners are involved in these phases, as idea generation may strongly benefit from high partner variety (Lazzarotti and Manzini, 2009); but different types of partners have different attitudes and requirements concerning IP (Hertzfeld et al, 2006;Slowinsky et al, 2009;Mehlman et al, 2010).…”
