“…Consequently, we restrict our attention to those papers that analyze firms' decisions in the presence of an SSO: these papers focus on the firms' intellectual property holding (Layne‐Farrar et al, 2014), their pool of patents (Layne‐Farrar & Lerner, 2011), their timing of entry in an SSO (Kauffman, unpublished), firms' choosing which SSO to join (Chiao et al, 2007; Lerner & Tirole, 2006), firm switching costs (Chen & Forman, 2006), firm efficiency differences and externality effects with R&D intensity (Gupta et al, 2008), and so forth. Despite drawing attention to the aforementioned body of the literature, there are also distantly related yet notable strands of the literature, for instance, Llanes and Poblete (2020), where the efficiency of SSOs when competition between groups of technology sponsors (firms) affect the standard‐setting process; also of note is Fiedler et al (2018), who analyze (i) standard‐essential patents' pricing alongside industry profits, and welfare and the incentives for innovators with heterogeneous R&D profiles to participate in the formation of SSOs and (ii) the incentives to lobby and to become active in the SSO's committees. In briefly addressing the empirical literature, we find that there is research that also analyses the firms' decision to join SSOs: Blind (2010), Blind (2016), Rysman and Simcoe (2008), and Simcoe et al (2007).…”
