Singapore PPH Updates: Faster, Simpler and More Efficient Patent Prosecution 20 Jun 2026 The Patent Prosecution Highway (PPH) has long been a useful tool for applicants seeking faster and more efficient patent protection in Singapore. By relying on the search and examination results from partner offices, applicants can streamline prosecution and improve their chances of obtaining a grant. The Intellectual Property Office of Singapore (IPOS) has recently introduced important updates to its Patent Prosecution Highway (PPH) framework, aimed at making patent prosecution faster, simpler and more efficient. These updates are set out in Patents Circular No. 2 of 2026 and Patents Circular No. 3 of 2026, alongside revised guidance on the IPOS website. These updates focus on three key areas: faster examination timelines, simplified fee arrangements, and a more streamlined amendment process through the Invitation to Amend (ITA). Together, they significantly improve both the speed and clarity of PPH prosecution. Accelerated First Office Action One of the most notable changes is the introduction of accelerated timelines for the first office action. For PPH requests filed on or after 1 July 2026, IPOS will issue the first office action within six months from the date of the request. This represents a clear improvement in predictability and speed. While PPH has always been intended to accelerate examination, the new timeline provides applicants with greater certainty on when they can expect to receive the first office action. This is particularly valuable for applicants managing parallel filings across multiple jurisdictions, where timing plays a critical role in coordinating prosecution strategies. Simplified Fee Structure – Upfront Savings Another important update relates to the fee structure for PPH requests. Under the previous practice (introduced in 2025), applicants were required to pay the full official fees at the time of filing and would subsequently receive a 30% refund. While effective in reducing overall cost, this approach created some practical inconvenience. Applicants had to track refunds, and the financial benefit was not immediate. Under the new system, from 3 August 2026 to 31 December 2027 (both dates inclusive), applicants filing a PPH request together with a new request for a search and/or examination report need only pay 70% of the prevailing official fees for the latter. This change offers several advantages: Immediate cost savings at the point of filing Reduced administrative burden (no need to track refunds) Greater transparency in budgeting In essence, the financial benefit of using PPH remains the same, but the process is now simpler and more convenient. Clarification of Invitation to Amend (ITA) A key development highlighted in Patents Circular No. 3 of 2026 is the clarification and enhanced use of the Invitation to Amend (ITA) within PPH and Global PPH (GPPH) applications. The ITA process allows the Registrar to invite applicants to make amendments to address specific issues identified during examination, instead of issuing a full written opinion. This is typically used where the issues can be resolved through relatively minor amendments or where prior discussions have already taken place between the applicant and the Examiner. Once an ITA is issued, the applicant has two months to respond. If no response is filed, the Examiner may proceed to issue a written opinion or examination report. One of the most significant improvements is the streamlined workflow for PPH and GPPH applications involving ITA. Since 27 September 2023, IPOS has introduced a streamlined process to eliminate the need for the applicant to withdraw and refile Patents Form 11 or 12 to submit amendments with the PPH or GPPH request, as follows: a. The applicant files a request for a search and examination report or an examination report (using Patents Form 11 or 12). b. The applicant subsequently requests accelerated examination under PPH or GPPH, indicating that amendments are required to conform the Singapore claims to the foreign allowable claims in the corresponding application filed with the selected PPH or GPPH office. c. The Registrar verifies with the Examiner that examination has not commenced. d. The Examiner begins examination by assessing whether conforming claims to the foreign allowable claims would resolve one or more prescribed matters. e. If the Examiner determines that one or more prescribed matters can be resolved by ITA without a written opinion, the Examiner may request the Registrar to issue the ITA. Conclusion Overall, the 2026 updates reinforce the strengths of the PPH framework in Singapore. Applicants now benefit from faster timelines, simpler fee arrangements and a more efficient amendment process. These improvements reduce administrative burden and allow applicants to focus on substantive prosecution strategy. From a practical perspective, applicants should consider making greater use of the PPH route where strong foreign examination results are available. The combination of accelerated timelines, upfront cost savings and the streamlined ITA process means that PPH applications can proceed very quickly and efficiently in Singapore. In summary, the latest updates demonstrate IPOS’ continued commitment to delivering a fast, efficient and user-friendly patent system. The enhanced PPH framework further strengthens Singapore’s position as a leading innovation hub in the region.
