Excluded Days Declared by IPOS in 2022 (so far)

8 June 2022

As you may recall from this blog, IPOS issued a number of announcements of days that are to be treated as “excluded days” under the various intellectual property Acts.

IPOS initially declared a period of excluded days at the end of April and begining of May 2022 in conjunction with the launch of a new electronic filing system. This was to take into account any possible disruption during the transition between the retirement of the old IP2SG electronic filing system and the launch of “IPOS Digital Hub”, the next generation electronic online system.

Unfortunately, the disruption has been more extensive than anticipated. IPOS has acknowledged that “some users are facing issues with certain transactions”.

Given this, IPOS has declared a number of further periods of excluded days for business before the office.

This post attempts to summarise the current situation with regard to excluded days before IPOS in the first half of 2022.

IPOS Excluded Days: Transition from IP2SG to IPOS Digital Hub

18 April 2022

UPDATED 28 April 2022: IPOS has announced a delay in the proposed launch of IPOS Digital Hub to 2 June 2022 (details below). New excluded days will be announced. Despite the delayed launch, the excluded days declared by IPOS and discussed in this post are not affected.

The Intellectual Property Office of Singapore has announced the launch of a new electronic filing system for patents, trade marks and designs, called IPOS Digital Hub.

On 29 April 2022, IPOS will retire its existing e-filing system (IP2SG), which has been in use since February 2014. The plan is for IPOS Digital Hub to go live on 4 May 2022.

On 25 May 2022, IPOS will retire its existing e-filing system (IP2SG), which has been in use since February 2014. The plan is for IPOS Digital Hub to go live on 2 June 2022 at 1200 hrs Singapore Time.

IPOS Digital Hub will then become the default electronic online system (EOS) for patent, trade mark and registered design filings in Singapore.

In order to implement these changes, IPOS has issued a Practice Direction setting out a number of excluded days.

TL;DR In combination with an intervening weekend and a couple of public holidays in Singapore falling within this period, the entire period from 29 April 2022 to 8 May 2022 is excluded for the purposes of transacting business with IPOS.
