In transactions involving IP rights, intellectual property can be a value driver or a hidden risk. Because these rights are intangible, legal and practical issues around ownership, scope, formalities, and recordal may only come into focus when a transfer is being documented or reviewed. This Practice Note, 'Assigning Intellectual Property Rights', discusses the statutory provisions governing the assignment of IP rights in Hong Kong and provides expert insight on the formalities for the legal assignment of patents, trade marks, copyright, and designs, including partial assignment and future IP rights. It also sets out practical tips for assignors and assignees and includes a mini checklist of key points to consider when assigning IP rights.
Key issues highlighted
Formalities for assigning patents, trade marks, copyright and registered designs
The Practice Note explains that the formalities for assigning IP rights are governed by statute. While the position is broadly aligned across the core rights, there are important differences in how each right may be assigned and whether partial assignment is available.
Key points include:
- Trade marks: the assignment of a registered trade mark or an application for a registered trade mark is not effective unless it is in writing and signed by or on behalf of the assignor. The assignment can be full or partial.
- Registered designs: an assignment of a registered design or an application for a registered design must be in writing and signed by or on behalf of the assignor. The Registered Designs Ordinance does not provide for partial assignment.
- Patents: an assignment of a patent or patent application must be in writing and signed by or on behalf of the assignor. The Patents Ordinance does not provide for partial assignment of a patent.
- Copyright: an assignment of copyright must be in writing signed by or on behalf of the assignor, and it may be partial, whether by reference to some but not all exclusive rights, or part of the copyright period.
The Practice Note also highlights a drafting point that can have practical consequences. Wording such as 'shall assign' or 'agrees to assign', as opposed to 'hereby assigns', will not amount to a legal assignment and may operate only as an equitable assignment.
Future IP rights, due diligence, and recordal
The Practice Note also addresses future IP rights. It notes that, to be effective, the provision must operate as a current assignment of future rights, and then sets out the position for future copyright, future trade marks, future patents, and future database right.
Before acquiring an IP right or an application for one, due diligence enquiries are advised. For registered rights, a search at the Hong Kong Intellectual Property Department can help confirm ownership, status and any registered licences. For unregistered rights, parties should clarify which rights are being assigned, who owns them, their scope, and whether any licences or third-party claims exist.
Once an assignment is in place, it is advisable to register or record it against the relevant rights at the IPD. Recordal is not compulsory, but it can affect priority against third parties. It may also affect financial relief in relation to registered trade marks and patents, and for registered designs it may affect reliance on the assignment in court as evidence of title. The Practice Note also notes practical points such as listing the assigned rights in a schedule and, where confidentiality is a concern, filing a simple assignment separately at the IPD.
