If you’re planning to file a patent in Singapore, it’s important to understand how the process is administered and what requirements your invention must meet. The Intellectual Property Office of Singapore (IPOS), the national authority responsible for patent registration and administration, evaluates each application to determine whether it qualifies for protection. To secure a patent, applicants must ensure their invention meets the legal standards set by IPOS and submit documentation that clearly supports each requirement.
What is a patent in Singapore?
In Singapore, the Intellectual Property Office of Singapore (IPOS) grants patents only when inventions meet three essential criteria. To secure a patent, you must prove that your invention satisfies each of the following standards:
-
Novelty: Your invention must be new and must not have been disclosed anywhere in the world before filing.
-
Inventive Step: Your invention must represent a genuine improvement and must not be obvious to someone skilled in the field.
-
Industrial Applicability: Your invention must be useful and capable of being manufactured or applied in industry.
Unlike other jurisdictions, Singapore excludes specific subject matter from patent protection. In particular, IPOS does not grant patents for:
-
Methods of medical treatment for humans or animals.
-
Inventions that contradict public order or morality, including those that promote offensive, immoral, or anti-social behavior.
Some of Singapore patent reports:
- Patent applications filed in 2024: 13,421.
- Patents granted: 7,230
- Top three technology areas for granted applications: 1) chemistry & Metallurgy (C): 23.74%; 2) Human Necessities (A): 20.90%; 3)Electricity (H): 18.74%
How to file a patent in Singapore?
In Singapore, patents can be filed either directly with IPOS through the domestic route, or by entering the national phase under the PCT.

- at least one way of carrying out the invention claimed, with a clear and detailed disclosure of the invention.
- technical background.
- drawings, if any (in grayscale)
3. Claims, key consideration:
- should define the invention in terms of its technical features (not commercial or non-technical statements allow).
- at least one claim relating to the invention,
- clear and sufficiently detailed description of the invention.
- the set of claims in a patent application in Singapore can pertain to only a single invention.
4. Abstract of the invention
- A brief summary highlighting the technical disclosure of the invention.
- Helps the public and examiners understand the essence of the invention quickly.
- Should not be used to interpret the scope of protection (which is defined only by the claims)
5. Specification, must be sufficiently detailed to enable a person skilled in the art to reproduce the invention:
- Disclose all technical features necessary to make the invention work, especially new ones.
- For a process or method → all relevant steps must be disclosed.
- For an apparatus or product → details of the structure, how it works, and how to make it.
Language Requirements
All documents must be submitted in English, which is the official language of IP filings in Singapore.
How is the Patent process in Singapore?
Once you file your patent application, the Intellectual Property Office of Singapore (IPOS) starts the granting procedure. You must stay proactive during this process, monitor all notifications, and respond promptly to official actions to avoid delays or rejection. The procedure generally follows these steps:
-
Preliminary Examination – IPOS checks whether the application meets the basic filing requirements.
-
Publication – IPOS publishes the application 18 months after the priority or filing date, unless you request early publication.
-
Substantive Examination – IPOS examines the application to determine if it meets the patentability criteria.
-
Notice of Eligibility for Grant – If you satisfy all requirements, IPOS issues a notice confirming the application’s eligibility for grant.
-
Issuance of Grant – IPOS grants the patent and publishes it in the Patents Journal.
-
Maintenance – You must pay annual renewal fees to keep your patent in force.

Some Extra Facts
Disclosure of Invention Prior to Filing
In Singapore, an invention loses novelty if the inventor discloses it to the public before filing a patent application (for example, through a scientific article, investment pitch, or exhibition). Such disclosure can invalidate the patent or lead to its revocation.
However, Singapore offers a 12-month grace period (for applications filed on or after 30 October 2017) to mitigate this risk. This grace period applies when:
-
The inventor (or someone deriving the invention from them) discloses the invention.
-
An IP office publishes an IP right that includes the invention.
To rely on this exception, applicants must notify IPOS and file a Statutory Declaration, including supporting documents when necessary, asking IPOS to disregard the earlier disclosure.
Patent Term and Maintenance
A patent in Singapore is valid for 20 years from the filing date of the application. Furthermore, if a patent term extension is granted, protection may last beyond this period, up to the end of the extended term. Nevertheless, to maintain the patent in force, applicants must pay annual renewal fees throughout its duration.
Duration of the Registration Procedure
The patent registration process in Singapore typically takes about 24 months from filing to grant. However, this duration depends on the complexity of the invention and the responsiveness of the applicant during examination. In addition, accelerated examination routes are available for applicants who require faster protection.
Representation by a Patent Attorney
While it is not mandatory to appoint a patent agent when filing in Singapore, applicants are strongly encouraged to seek professional assistance. Indeed, preparing a patent application involves complex legal and technical requirements — from drafting claims that define the scope of protection to ensuring that the description is sufficiently detailed and compliant with IPOS standards.
Moreover, applicants who are not based in Singapore must provide a local address for service. Therefore, engaging a registered patent agent ensures compliance with this requirement and facilitates direct communication with the Intellectual Property Office of Singapore (IPOS).
