A granted Singapore patent requires ongoing renewal fees to stay in force for its full 20-year term. Our team at Brealant tracks your renewal dates and manages payment so your rights never lapse.
Legal Definition of Patent Renewal
Renewal fees are annual payments due to IPOS under the Patents Act 1994, generally starting from around the fourth anniversary of the filing date.
Grace Period Only
The grace period is the outer limit — after that, restoration options are very limited.
Doesn't Extend the Term
Renewal maintains the patent within its existing 20-year term; it doesn't extend that term.

In Singapore, renewal fees generally fall due annually from around the 4th anniversary of the filing date through to the 20th year of the patent's term. IPOS allows renewal ahead of each due date, with a grace period after, subject to a late fee.
Missing a renewal fee, including the grace period, causes the patent to lapse, often with very limited restoration options. Brealant's centralised tracking removes this risk, especially for businesses managing multiple patents or jurisdictions.
Renewal keeps a patent in force, but it has boundaries
No Substantive Changes
Renewal cannot be used to change the claims or scope of the granted patent.
Grace Period Only
The grace period is the outer limit — after that, restoration options are very limited.
Doesn't Extend the Term
Renewal maintains the patent within its existing 20-year term; it doesn't extend that term.
Doesn't Prevent Challenge
A renewed patent can still be challenged for validity through revocation proceedings.
Ownership Must Be Current
Renewal doesn't update ownership records — an assignment must be separately recorded if the owner has changed.
Brealant reviews your patent's status as part of every renewal to flag any of these issues early.
Renewal keeps the full benefit of your grant in place, including
Exclusive Rights
Your continued exclusive right to make, use, and sell the invention across Singapore.
Licensing Revenue
The ongoing basis for any existing or future licensing arrangements.
Enforcement Standing
Your ability to take infringement action based on a patent that remains in force.
Commercial Value
The market value of your patent as a business and investment asset.
Renewal is a simple, recurring step that preserves everything your grant achieved.

Yes, IPOS allows a 6-month grace period to pay a late renewal fee, though a surcharge applies and the patent lapses if the deadline is missed entirely.
Yes, in certain circumstances an application for restoration can be made to IPOS, but it requires showing the failure to renew was unintentional and must be filed within the prescribed period.
No, renewal fees are based on the patent's age, not on whether it was granted via supplementary or full examination.
Yes, once granted in Singapore under the supplementary examination route, the patent is renewed the same way as any other Singapore patent.
IPOS does not guarantee a reminder, so Brealant recommends we track your renewal calendar directly to avoid an inadvertent lapse.
