Term and renewal
The term of a patent is 20 years from the Date of Filing of the patent application, subject to the payment of annual renewal fees.
To maintain your patent, you will need to pay an annual renewal fee, starting from the end of the 4th year from the Date of Filing, and every year thereafter, until the patent expires.
In the event that grant was issued after 45 months from date of filing, all renewals due will only be payable within 3 months after the date of grant.
You can renew your patent by submitting Patents Form 15 together with renewal fees. If you have made an entry in the register for Licence of Right, you can renew your patent at half price, using Patents Form 53.
Licence of Rights
Applying for a License of Right
If you are interested in licensing your patent to a third party, you may wish to endorse your patent with a Licence of Right (LOR) after the patent is granted. This can be done by applying for an LOR entry to be made in the Patents Register. An LOR may help you attract licensees, and your patent renewal fees that are payable after the LOR entry is made would also be halved. However, this means that you cannot refuse to license the invention. The terms of the LOR are to be negotiated between you and the licensee. If both parties are not able to reach an agreement on the terms of the LOR, either party may request the Registrar to settle the terms of the LOR.
To apply for an LOR entry to be made in the Patents Register, you will need to complete and submit Patents Form 28 (S$70). If the Registrar is satisfied that you are not precluded by contract from granting licences under the patent, he shall make the LOR entry.
Cancelling a License of Right
If you wish to cancel an LOR entry in the Patents Register, you will need to complete and submit Patents Form 30 (S$70). If the Registrar is satisfied that there is no existing licence under the patent or that all licensees under the patent consent to the application, and the balance of all renewal fees which would have been payable if the entry had not been made have been paid, the Registrar may cancel the entry.

Obtaining a license to a patent
If you are interested in obtaining a licence to someone's patent but do not know where to start, you may start by looking at our Patents Register for patents that are endorsed with a licence of right entry. To facilitate the search process, IPOS has consolidated a list of Singapore patents with such endorsements. The LOR list contains details of all live granted patents with a LOR status extracted from the Patents Register. However as the LOR status of a patent can change (e.g. if a LOR endorsement is cancelled), you should check the Patents Register before relying on the information in this list.
