Patent Register Transfer
Meaning
Administrative recording entries made on the official patent register by the national intellectual property agency formalize the change of patent ownership between assignors and transferees. Executing a patent register transfer moves legal title, enforcement standing and licensing rights to the new owner under national patent statutes. The transfer scope stops at registered patent rights and does not automatically assign unpatented trade secrets or manufacturing know-how.
Recordation Procedure
Parties submit executed assignment contracts, transfer application forms and corporate qualification documents to administrative reviewers. Foreign cross-border transfers require prior commerce department export approval certificates before registration can occur. Incomplete applications or defective seal authorizations delay official register entries.
Registrations complete upon publication in the official patent gazette.
Legal Effect
Ownership title vests in the transferee strictly on the calendar date of official register publication. The recorded assignee acquires exclusive legal standing to file civil patent infringement lawsuits and collect past damages. Unrecorded transfers remain contractual obligations between parties but convey no statutory property rights against third parties.
Third Defense
Public registration records protect good-faith purchasers from unrecorded prior assignments or undisclosed security interests. Registered assignees hold priority over competing unrecorded claimants in judicial ownership disputes. Invalidation actions against assignments fail when based on unrecorded private side agreements.
