To improve commercialization efficiency and reduce ownership disputes, this study examines delayed IP planning, insufficient protection scope and weak value assessment from patent search, achievement ledger, ownership confirmation and pre-contract management. It proposes a “one database, two maps, three lists and five nodes” mechanism that embeds R&D screening, achievement identification, ownership division and commercialization agreements into the whole R&D process, thereby improving marketability. IP management should be advanced during project initiation, R&D, pilot testing, filing and commercialization negotiation.
