This paper aims to design the optimal structure of an innovation intermediary organization and its open innovation platform to facilitate the process of commercialization of inventions as well as establish efective communications between industrialists and researchers and inventors. Even though the issue of creating an open innovation platform and its design was raised in other research, the optimal structure that was extracted from the experience of working in the feld of commercialization of inventions in a long-term period has not been done. Using the case study research methodology for seven years (from 2012 to 2018) in seven phases, we studied the obstacles in the way of, and strategies for, the development of the innovation intermediary organization in Iran, and proposed a model for the open innovation platform belonging to this innovation intermediary organization at the end of the 7th phase. The tool for gathering information is the review of open innovation organization documents and semi-structured interviews with 15 experts and managers of this open innovation organization. By categorizing the obtained codes, the intended themes were extracted. Then, Cohen's Kappa coefcient was used to measure the reliability of the obtained codes, the value of which was equal to 0.85, indicating the high reliability of this research. Also, to strengthen the credibility of this qualitative research, environmental observations and analyzed data were used to provide respondents with their opinions. The obtained fndings indicate an appropriate structure for the innovation intermediary organization and its open innovation platform to accelerate the identifcation of the needs of industries, creating solutions for these needs, as well as supporting patents and entrepreneurial plans. In this structure, various components of the innovation ecosystem interact with each other, including universities, research centers, experts, start-ups, investors, entrepreneurs, science and technology parks, and accelerators. The results of the study show that by collaborating with this platform, universities can provide job opportunities for students in various felds. By joining this platform, industries will be able to meet some of their technological needs. Furthermore, entrepreneurs can use this platform to fnance their entrepreneurial projects using investors and acquire their required experts.
