Overview of the registration process

This is an illustrated example of the registration process. Your registration process may vary, depending on your application requirements or if there are opposition proceedings.

IPOS offers various acceleration programmes to help applicants speed up the registration process. One of these programmes is the Patent Prosecution Highway (PPH), where applicants can accelerate the examination of their IPOS patent application by relying on the examination results issued by one of our over 30 PPH and Global PPH partners, including the patent offices of China, Japan, Korea, United States, and the European Patent Office.

Step 1: Check registration criteria for a patent

Before applying to register your patent, you should check if your patent fulfils the registration criteria. Here are four quick questions to guide you on determining the registrability of your patent:

a) Is your invention patentable?

For an invention to be patentable, it must, in general, satisfy three key criteria:

New – The invention should not be publicly known in any way, anywhere in the world. Owners of inventions should be careful to keep the invention secret until a patent application has been successfully made. If the idea has already been talked about, commercially exploited, advertised or demonstrated, then the novelty of the invention may be compromised.
Inventive step – The invention must be an improvement over any existing product or process that is already available. The improvement must not be obvious to someone with technical skills or knowledge in the field of the invention.
Industrial application – The invention must be useful and have some form of practical application. It should be capable of being made or used in some form of industry.

A method of treatment of the human or animal body by surgery, therapy or diagnosis practised on the human or animal body is not patentable.

An invention that is generally expected to encourage offensive, immoral or anti-social behaviour will not be published or patentable.

b) Did you disclose your invention to anyone?

Disclosing your invention may compromise the novelty and affect your patent application.

If your invention needs to be disclosed to a third party before a patent application is made, it is a good idea to draw up a non-disclosure agreement (NDA). Disclosure to the invention can be made after a date of filing has been obtained for the application.

c) Did you check whether there are existing inventions similar to yours?

Before you apply for a patent, it is a good idea to run a search on existing patents to see if your invention already exists. You can also avoid scenarios where there might be possible infringement of other patents filed or granted.

You may tap on online databases such as IPOS Digital Hub to search or engage professional services.

d) Are you entitled to register for the patent?

You are entitled to register the patent if you are:

An employer and the invention was made by your employee in his normal course of duties;
A person who has entered into an agreement with the inventor before making the invention, such that you are entitled to the invention; or
The inventor.

Step 2: Apply for a patent

Before you apply to register a patent, learn more about the different options available.

Registering a patent in Singapore

When applying for patent in Singapore, use this pre-filing checklist:

Determine what countries you intend to file for protection – The scope of patent protection, and the cost of protection, varies from country to country. Generally, protection should be sought in the countries which are your key markets.
Prepare a technical and accurate description of your patent – For your invention to be granted a patent protection that is effective, it is important that your patent applications are technically and legally accurate. This will save you time, money and increase your chance for a favourable patent application. You can consider engaging the services of a registered patent agent to assist with the submission of your patent application. Alternatively, you can refer to the information sheet [PDF, 232 KB] on requirements for filing patent applications with IPOS.
Ensure your claims are ready – If your claims are not fully ready, you may apply for a Provisional Application to secure an early filing date for your invention. However, as claims are essential in defining the scope of protection sought, it should be furnished within 12 months* to complete the patent application. Failure to do so would result in the patent application being treated as having been abandoned.
Obtain a written authorisation from IPOS – If you are residing in Singapore and plan to apply for a patent outside of Singapore first, you need to obtain a written authorisation from IPOS for national security clearance before doing so. Failure to do so would result in you being liable to a fine and/or imprisonment.

There are two routes of applying for a patent in Singapore – directly with IPOS via domestic route, or through PCT National Phase Entry route.

Registry of Patents Quality Policy

We strive to work effectively with all interested parties to provide quality products and services to the satisfaction of our customers and meet the applicable requirements. We are committed to improving our systems and processes for greater validity, reliability, and timeliness of our products and services.

Registering a patent outside of Singapore

Patent protection is territorial in nature. This means that if you wish to protect your patent in another country outside of Singapore, you must also file for patent registration in that country.

To obtain patent protection overseas, you can either:

File individual applications in the countries concerned; or
Use the Patent Co-operation Treaty (PCT), which facilitates the filing of International Applications.

IMPORTANT NOTE: If you are a Singapore resident, you are required to obtain written authorisation from IPOS before filing an application for a patent outside of Singapore. This is called a National Security Clearance.

Step 3: Forms and fees for new applications

Please proceed to our e-services portal, IPOS Digital Hub, to file your forms online. The acceptable modes of payment can be found here.

We will only accept FormSG for forms/requests that are not available for e-filing in IPOS Digital Hub. However, in respect of national security clearance, submissions could be made via IPOS Digital Hub.
