Meaning
Judicial preservation measures executed by Chinese courts freeze intellectual property assets to secure monetary judgments or prevent unauthorized asset dissipation during litigation. Carried out as a patent seizure, the court issues a formal assistance notice to the national IP authority to restrict the patent owner from transferring, licensing or pledging the patent rights. This judicial enforcement action governs invention patents, utility models and design patents, remaining in effect until court proceedings finalize or alternative financial security is posted.
Judicial Execution
Intermediate people’s courts order property freezes upon application by a claimant who provides matching counter-security. In executing a patent seizure, the court sends an official enforcement order alongside an assistance in execution notice directly to the China National Intellectual Property Administration. The entry of this order in the official patent register instantly blocks all voluntary legal transactions involving the patent.
Administrative Registration
Recordation of the court order in the national patent database establishes public notice against third parties. Unrecorded court orders fail to defeat subsequent good-faith assignments registered with the patent office.
Commercial Limitation
Freezing patent ownership rights restricts title transfers without halting ongoing operational exploitation by existing licensees. A patent seizure prevents the owner from encumbering the patent, assigning ownership to offshore holding entities, or executing exclusive licensing deals to dilute asset value. Existing non-exclusive license agreements executed prior to the seizure remain valid, allowing royalties to be directed into court-monitored escrow accounts.
Should the court rule against the patent owner, frozen patent rights can be valued by accredited appraisal agencies and auctioned through judicial online platforms to satisfy court judgments.
