Whether you're acquiring a patent, restructuring a business, or transferring rights between related entities, the change of ownership needs to be properly documented and recorded with IPOS. Our team at Brealant handles the assignment paperwork and the recordal.
Legal Definition of Patent Assignment
Assignment, under the Patents Act 1994, is the legal transfer of ownership of a patent or patent application from one party to another.
Doesn't Renew the Patent
Assignment and renewal are separate processes — a transferred patent still needs to be renewed on schedule.
Doesn't Change the Claims
You can't use an assignment to alter the granted claims or scope of protection.

Response
You receive confirmation once ownership is updated on the register.
In Singapore, an assignment is only as strong as its documentation and recordal. A signed deed of assignment, followed by a recordal request to IPOS, is the clearest way to make sure the change of ownership is properly reflected and enforceable.
An unrecorded change of ownership can create uncertainty about who can enforce or license the patent, and may weaken the new owner's position in a dispute. Brealant keeps the register accurate and the new owner's rights clearly established.
Recordal is important, but it has limits
Doesn't Validate a Bad Deal
Recordal reflects the transfer; it doesn't cure defects in the underlying commercial agreement.
Doesn't Renew the Patent
Assignment and renewal are separate processes — a transferred patent still needs to be renewed on schedule.
Doesn't Change the Claims
You can't use an assignment to alter the granted claims or scope of protection.
Retrospective Effect Is Limited
Recordal protects the new owner going forward; earlier unrecorded dealings may need separate legal advice.
Doesn't Resolve Disputes
If ownership itself is disputed, recordal won't resolve the underlying dispute.
Brealant flags any of these issues during the assignment process so nothing is missed.
A properly recorded assignment protects
The New Owner's Rights
Clear, documented legal ownership recognised by IPOS.
Enforcement Ability
The new owner's standing to take infringement action based on the patent.
Deal Certainty
The commercial transaction — acquisition, restructure, or licence — that the transfer is based on.
Future Dealings
The ability to further assign, license, or use the patent as security without ownership disputes.
Brealant makes sure every assignment is properly documented so these protections are secured.

Recordal

Assignment costs are modest relative to the transaction they support

IPOS charges a modest official fee per patent to record an assignment.
IPOS charges a modest official fee per patent to record an assignment.
These costs are a small part of protecting the value of the IP asset being transferred.
Once the assignment is recorded, Brealant can take over ongoing renewal tracking, monitoring, and enforcement for the new owner, so the transition is seamless.

It isn't required for the transfer to be valid between the parties, but recording it is important for the new owner to be recognised and to protect their position against third parties.
Yes, both pending applications and granted patents can be assigned.
IPOS requires documentary evidence of the transfer, such as a signed deed of assignment.
Yes, we regularly coordinate Singapore recordals alongside assignments of corresponding patents in other jurisdictions.
Once signed documentation is filed, IPOS typically records the change of ownership within a few weeks.
Yes, a Singapore patent can be jointly owned, and any assignment involving co-owners should clearly document each party's resulting share and rights.
Yes, IPOS charges an official recordal fee, which Brealant confirms and includes in your quote before filing.
Yes, licensing lets the original owner retain the patent while authorising another party to use it, and the licence can also be recorded with IPOS.
An unrecorded assignment can still bind the parties to it, but it may not be enforceable against a third party who later acquires an interest in good faith, and the register will still show the original owner.
Yes, we regularly coordinate assignments across multiple jurisdictions where an applicant holds a family of related patents, including foreign counterparts used for supplementary examination.
