Open Innovation (OI) is an innovation paradigm first theorized in 2003 by American economist and author Henry Chesbrough.
It is a strategic and cultural model of decentralized and distributed innovation. According to this approach, for a company to enhance and advance multidisciplinary expertise, stay competitive, or improve its market position in the medium to long term, it cannot rely solely on internal know-how and in-house research and development (R&D). Instead, it must open up to the market of knowledge and technology, integrating new ideas and turnkey solutions from external sources—while also strategically externalizing its own innovations.
This can be achieved through collaboration agreements, industrial partnerships (e.g., joint ventures), patent acquisitions or sales, licensing agreements, mergers and acquisitions (M&A), or the creation of spin-offs, spin-outs, and new companies (newcos). By doing so, companies stimulate not only organic growth but also inorganic expansion through external avenues, fostering cross-pollination, mutual enrichment, and strategic alliances.
