What is IP2SG?
IP2SG is your one-stop portal that facilitates online Singapore patents-related
transactions and searches.
Basic Requirements for using IP2SG eServices
Changes to the Account and Password Reset
- Is it mandatory to register for an IP2SG eServices account ("Account")?
No. The electronic filing system has been revamped. There are two online portals
- the public portal and the customer portal. The public portal can be accessed without
having to register or log in. The customer portal requires users to register first
and after that, to log in so as to access the portal.
- What are the benefits of registering for an Account?
Registering for an Account gives access to the customer portal, which has more functions
than the public portal. For example, in the customer portal, a user will be able
to track filing and payment details, and be able to send and receive correspondence
via the Correspondence Module (eCommunications).
- Who is eligible to register for an Account?
Anyone or any company can register for an Account. A Singapore address for service
and a valid SingPass is needed to register for and to use an Account. There needs
to be at least 1 user designated as an Administrator, duly authorised to manage
and transact under the Account. Others, designated as Users, can be authorised to
transact under the Account
- Is there an Account registration fee?
No. Registration is free.
- How do I register for an Account?
Registration can be done online here or
manually. To register for an Account online, the business or body corporate
must also have a valid Unique Entity Number ("UEN"). For the registration of individuals,
and registration of businesses or bodies corporate without a valid UEN, please manually
submit the registration form, which is available
here to IPOS. IPOS will issue an entity code for Account registration.
- When will my Account be activated?
For self-service online registration, your Account will be immediately activated
on successful registration. For manual registration, 3 to 5 working days are required
for an Account to be activated.
- Is a Netrust Certificate required for Account registration?
Hardware/ Software Requirements
- How do I terminate a user or an Account?
An Administrator can delete Users or other Administrators via the online administration
function. To terminate the Account itself, a written notice needs to be sent to
- What is the procedure for updating Account, Administrator or User information?
Please refer to our user manual for details
- I have forgotten my SingPass password. What should I do?
Please refer to the SingPass website for details
Online Filing/ Submissions
- What are the recommended hardware / software requirements for the use of IP2SG
To achieve a reasonable level of performance, please ensure you have the required
hardware and software as set out on the IP2SG website
- What if I do not have the required hardware or software?
IPOS has the appropriate computers available at its customer service area for public
use. Please approach the service counter at our office should you need to make use
of these computers.
Preparation of Documents for Electronic Submission
- What type of Patents Forms can be filed on IP2SG?
Details on the Patents Forms available at IP2SG may be found on the IP2SG
- Should I make a paper copy submission after filing it electronically with IP2SG?
No. Duplicate submissions on paper are not necessary. Doing so may cause confusion
and delay the processing of your matter.
- What if the file size of my submission (e.g. of the patent specifications) exceeds
the 100-megabyte (100MB) limit?
In the event that the 100MB file size limit is exceeded:
- For Patents Forms 1, 12, 13, 14, 17, 37, 56 and Form CM4, the applicant can proceed
to submit the electronic form online and follow up by submitting the document attachments
via portable media.
For other forms, the applicant can request the Registrar in writing to allow the
hardcopy form and documents to be submitted with the assistance of the service bureau
with a waiver of the service bureau fees.
- When can I file my patent application online?
IPOS will accept online filings 24 hours a day, 7 days a week, subject to availability
of the server, which will be under maintenance from time to time.
- Do I need to file a cover letter with my electronic submission?
A cover letter is not mandatory for electronic submissions. However, should you
wish to provide us with additional information, a cover letter can be optionally
attached to electronic submissions.
- How will I know that IPOS has received my electronic form submission?
An online "Acknowledgment and Receipt" page will be generated and displayed after
every submission. Applicants can print this page for record purposes. At the same
time, an "Email Online Receipt", which is a summary of the completed transaction,
is sent to the user via email. The technology involved in checking the completeness
and integrity of your transmission is part of the standard protocols used for online
- How will I know that IPOS has received my payment?
After payment is made, a receipt page will be generated and displayed. Applicants
can print this page for record purposes.
- How is the lodgement date accorded for an online submission?
- Where the Patents Forms and documents are submitted online, the lodgement date of
the submissions is the day the electronic filing is completely and successfully
received at IPOS, as shown on the "Acknowledgement and Receipt" page.
Where the Patents Form and documents are sent on portable media, the lodgement date
of the submission is the date the portable media is received by IPOS. Payment of
the filing fee alone will not be sufficient to secure a filing date. Both the filing
fee and the portable media containing the documents comprising the submission must
be received by IPOS in order to secure a filing date.
- What is the Online Save Feature for Patents Forms?
This feature is available for all Patents Forms. It allows you to save the details
which you have keyed into the online Patents Forms on our server for a maximum of
30 days. You must complete the submission or resave the details before the end of
the 30 days, or the details will be deleted. There is no limit on the number of
electronic Patents Forms that each user can save.
- Why are the addresses of applicants not auto-populated when applicants are selected
from an applicant dropdown list?
In such cases, please manually enter the applicant's address first. Subsequently,
when this same applicant is added again (i.e. with the same name and UEN/ Applicant
Code), the applicant's address will be auto-populated by the system.
Portable Media Submission to IPOS (for files which exceed 100MB)
- What file format must electronically-submitted documents be in?
Applicants are only allowed to electronically submit documents in the Portable Document
Format ("PDF"). Text-searchable PDF documents are recommended. Submitting information
in PDF guarantees that information is identically represented in different environments
and it also retains the integrity of the data.
- How should applicants prepare documents e.g. patent specifications before attaching
them to the online Patent Forms?
- Ensure that all the documents are A4-sized.
- Separate the patents documents into three separate electronic files in PDF format:
- description with claims, or description without claims;
- drawings (if any); and
In the PDF documents, do not activate any of the "locks" to prevent cutting and
pasting text from the document, as our system may need to place your preferred drawing
into the abstract if required.
- What are the recommended resolutions for electronic submission?
It is recommended that the PDF documents should be scanned at a resolution of 200
dpi with the exception of drawings which should be scanned at a resolution of 300
dpi. All images should be saved as black and white images or grayscale images. You
may wish to crop the images to reduce the surrounding white space.
- When should I use portable media?
You will need to submit documents on portable media should the attachments to the
Patents Forms exceed the 100MB limit for online submissions.
- What kind of portable media can I use?
Currently, Compact Disc Recordable ("CD-R") and Digital Versatile Disc Recordable
("DVD-R") are accepted. Please note that submitted portable media is not returnable.
- What should I take note of when using portable media to submit documents?
For the avoidance of doubt, note that a submission made on portable media is treated
as received by the Registry in the same manner as the receipt by the Registry of
submissions made by way of paper documents as provided in the Patents Rules. Portable
media sent to the Registry must be prepared in accordance with the instructions
below and must be accompanied by the receipt showing proof of payment for the relevant
submissions, to be considered a properly prepared submission:
- All documents stored on each piece of portable media (i.e. CD-R or DVD-R) must relate
to the same patent application.
- Each piece of portable media must be prepared as a single session data disc when
storing the electronic files onto CD-R or DVD-R.
- Label each piece of portable media accordingly by applying a self-adhesive label
to the portable media and ensure that the following details have been written in
indelible ink or printed onto the label:
- Subject: IP2SG submission.
- Name of the IP2SG account holder.
- Names of the electronic files stored on the portable media.
- The e-filing reference number.
- The patent application number (where available).
The applicant's own reference number (where available).
- After completing payment, print out two copies of the receipt. Keep one copy for
your reference. With the other copy, detach the bottom portion and secure it to
the outside of an envelope, and place the top portion into the envelope, with the
media and any other documents which you need to submit in paper form. Ensure that
the envelope is properly secured before sending it IPOS.
- All portable media containing the relevant documents accompanying the relevant form
submitted to the Registry must be accompanied by payment or the receipt showing
proof of payment for the relevant form, within a sealed envelope sent to the Registry
- posting the envelope with its contents to the Registry; or
- handing the envelope to the officers at the IPOS counter (during office hours);
dropping the envelope into the Patents Deposit Box (after office hours).
- What are the modes of payment available?
The available payment modes are:
