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

When should you apply for a patent?

In Singapore, the first person to file an application generally has priority over others for the same invention.

Singapore also allows priority claims to be made in a patent application. This means that if you have filed a patent application in a Paris Convention country or a World Trade Organization member country, and wish to subsequently file the same application in Singapore, you may claim foreign application as priority in the Singapore patent application, within 12 months.

Have you decided 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.

Do you have a technical and accurate description of the 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 on requirements for filing patent applications with IPOS.

Are your claims 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.

Have you obtained 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.
