However, patents do not provide a perpetual monopoly within the prevailing open innovation paradigm, which means that firms should keep up with innovation input and patent applications to preserve their market dominance. Fostering technological breakthroughs in the patent network thus becomes a critical issue. Anchored in the theoretical views of open innovation, this study conducts an empirical analysis of patent data to examine how patent network structural features influence the technologies\u2019 breakthrough tendency in the field of autonomous driving (AD). The findings indicate that centrality metrics such as degree centrality, harmonic centrality, and betweenness centrality within AD patent networks exert significant influence on technological breakthrough tendency, and the patent family size plays a moderating role in these relationships. Moreover, this research advances theoretical insights for patent strategy formulation in emerging firms of AD, with broader implications for other technology-intensive sectors.<\/jats:p>","DOI":"10.3390\/systems14060682","type":"journal-article","created":{"date-parts":[[2026,6,16]],"date-time":"2026-06-16T09:06:52Z","timestamp":1781600812000},"page":"682","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Technological Breakthrough Tendency in Patent Networks Under Open Innovation: Evidence from Autonomous Driving Patents"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8710-662X","authenticated-orcid":false,"given":"Ben","family":"Zhang","sequence":"first","affiliation":[{"name":"Law School, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0781-2955","authenticated-orcid":false,"given":"Runzhe","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Management, Huazhong University of Science and Technology, Wuhan 430074, China"},{"name":"Sino-European Institute for Intellectual Property, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"320","DOI":"10.1108\/EJIM-02-2021-0114","article-title":"Value capture in open innovation markets: The role of patent rights for innovation appropriation","volume":"25","author":"Holgersson","year":"2021","journal-title":"Eur.
