Key Provisions Governing Patent Administration and Their Purpose
The Patents Act 1994 establishes a comprehensive framework for the administration, maintenance, and enforcement of patents in Singapore. Part 7 of the Act contains critical provisions that regulate the grant, duration, amendment, re-examination, restoration, and surrender of patents. This analysis examines these key provisions, elucidating their purposes and the rationale behind their inclusion in the legislation.
Section 35: Notification and Publication of Patent Grant
"As soon as practicable after a patent has been granted under this Act, the Registrar must— (a) send to the proprietor of the patent a certificate in the prescribed form that the patent has been granted to the proprietor; and (b) publish in the journal a notice that the patent has been granted." — Section 35(1)

Section 35 mandates the Registrar to promptly notify the patent proprietor of the grant by issuing a certificate and to publish a notice in the official journal. This provision serves two fundamental purposes:
- Legal certainty and official recognition: The certificate formally evidences the grant of the patent, providing the proprietor with legal proof of their rights.
- Public awareness and transparency: Publication in the journal informs third parties and the public of the patent’s existence, enabling them to identify patented inventions and avoid infringement.
By ensuring timely communication and public disclosure, Section 35 supports the integrity of the patent system and facilitates the balance between private rights and public knowledge.
Section 36: Duration of Patent Protection
"A patent granted under this Act is treated for the purposes of this Act as having been granted, and takes effect, on the date of issue of the certificate of grant and, subject to subsection (2) and section 36A, continues in force until the end of the period of 20 years beginning with the date of filing the application for the patent or with such other date as may be prescribed." — Section 36(1)
Verify Section 36 in source document →
Section 36 establishes the standard term of patent protection as 20 years from the filing date of the application, subject to payment of renewal fees and possible extensions under Section 36A. The rationale for this provision includes:
- Encouraging innovation: A fixed term incentivizes inventors by granting exclusive rights for a reasonable period to recoup investments.
- Legal clarity: Defining the term provides certainty to patentees and third parties regarding the duration of protection.
- Balancing public interest: After the term expires, the invention enters the public domain, promoting further innovation and competition.
Section 36(1) also references Section 36A, which allows for term extensions under specific circumstances, reflecting the legislature’s recognition of potential delays or curtailments affecting patent exploitation.
Section 36A: Extension of Patent Term
"The proprietor of a patent may apply to the Registrar to extend the term of the patent on any of the following grounds: (a) that there was an unreasonable delay by the Registrar in granting the patent; (b) where the patent was granted on the basis of any prescribed documents referred to in section 29(1)(d) relating to one corresponding application or related national phase application, that— (i) there was an unreasonable delay in the issue of the corresponding patent or related national phase patent (as the case may be); and (ii) the patent office that granted the corresponding patent or related national phase patent (as the case may be) has extended the term of the corresponding patent or related national phase patent (as the case may be) on the basis of such delay; (c) where the subject of the patent includes any substance which is an active ingredient of any pharmaceutical product, that— (i) there was an unreasonable curtailment of the opportunity to exploit the patent caused by the process of obtaining marketing approval for a pharmaceutical product, being the first pharmaceutical product to obtain marketing approval which uses the substance as an active ingredient; and (ii) the term of the patent has not previously been extended on this ground." — Section 36A(1)
Verify Section 36A in source document →
Section 36A provides mechanisms for extending the patent term beyond the standard 20 years in specific situations, primarily to address delays and regulatory hurdles that unfairly reduce the effective patent life. The purposes include:
- Compensating for administrative delays: If the Registrar or a corresponding foreign patent office unreasonably delays granting the patent, the patentee can seek an extension to recover lost time.
- Addressing regulatory delays in pharmaceuticals: Recognising that obtaining marketing approval for pharmaceutical products can significantly delay commercial exploitation, this provision allows extensions to ensure patentees receive adequate protection and incentives.
- Maintaining international consistency: The provision aligns Singapore’s patent term extensions with those granted by corresponding patent offices, fostering harmonisation.
This section reflects a policy balance between protecting patent holders’ interests and ensuring that patent terms are not unduly prolonged without justification.
Section 37: Prohibition on Objections Based on Multiple Inventions
"No person may in any proceeding object to a patent or to an amendment of a specification of a patent on the ground that the claims contained in the specification of the patent, as they stand or (as the case may be) as proposed to be amended, relate— (a) to more than one invention; or (b) to a group of inventions which are not so linked as to form a single inventive concept." — Section 37
Verify Section 37 in source document →
Section 37 prohibits objections to a patent on the basis that the claims cover multiple inventions or unrelated groups of inventions. The rationale includes:
- Simplifying patent enforcement: Prevents challenges that could fragment patent claims and complicate enforcement.
- Encouraging comprehensive claims: Allows patentees to claim multiple related inventions without fear of invalidation on unity grounds.
- Reducing procedural complexity: Streamlines patent litigation and administrative proceedings by limiting grounds for objection.
This provision contrasts with some jurisdictions that require unity of invention and reflects Singapore’s policy to facilitate robust patent protection.
Section 38: Amendment of Patent Specifications
"Subject to this section and section 84, the Registrar may, on an application made by the proprietor of a patent, allow the specification of the patent to be amended subject to such conditions, if any, as the Registrar thinks fit." — Section 38(1)
Verify Section 38 in source document →
Section 38 empowers the Registrar to permit amendments to patent specifications upon the proprietor’s application, subject to conditions. The purposes are:
- Correcting errors and clarifying claims: Enables patentees to rectify mistakes or improve claim clarity to better define the scope of protection.
- Maintaining patent validity: Allows amendments that ensure the patent remains enforceable and consistent with the invention disclosed.
- Balancing interests: The Registrar’s discretion and conditions safeguard against amendments that could unfairly extend protection or harm third parties.
This provision ensures flexibility in patent administration while protecting the integrity of the patent system.
Section 38A: Re-examination of Patent Specifications
"Any person may, at any time after a patent is granted, file a request for the Registrar to conduct a re‑examination of the specification of a patent for an invention on any of the following grounds: (a) the invention is not a patentable invention; (b) the specification does not disclose the invention clearly and completely for it to be performed by a person skilled in the art; (c) the matter disclosed in the specification extends beyond that disclosed— (i) in the application for the patent, as filed; or (ii) where the patent was granted on a new application filed under section 20(3) or 47(4) or section 116(6) of the Patents Act (Cap. 221, 1995 Revised Edition), or in accordance with section 26(11), in— (A) the earlier application made under this Act; (B) the application made under the United Kingdom Patents Act 1977; or (C) the application under the European Patent Convention designating the United Kingdom filed at the European Patent Office, as the case may be, from which the filing date and the right of priority has been derived, as filed; (d) an amendment has been made to the specification of the patent under section 38(1), 81 or 83 which— (i) results in the specification disclosing any additional matter; or (ii) extends the protection conferred by the patent; (e) an amendment has been made to the specification of the application for the patent under section 31 which results in the specification disclosing any matter extending beyond that disclosed in the application as filed; (f) a correction has been made to the specification of the patent or of the application for the patent under section 107 which should not have been allowed; (g) the patent is one of 2 or more patents for the same invention having the same priority date and filed by the same party or the party’s successor in title." — Section 38A(1)
Verify Section 38A in source document →
Section 38A allows any person to request re-examination of a patent’s specification after grant on various substantive and procedural grounds. The purposes include:
- Ensuring patent quality and validity: Provides a mechanism to challenge patents that may not meet patentability criteria or have improper disclosures.
- Protecting public interest: Prevents unjustified monopolies by allowing correction or revocation of patents that exceed their legitimate scope.
- Maintaining procedural fairness: Grounds for re-examination cover amendments and corrections to prevent abuse of the amendment process.
- Harmonising with international standards: References to UK and European patent applications ensure consistency in assessing priority and disclosure.
This provision is crucial for post-grant scrutiny, balancing the rights of patentees with the need to safeguard the public domain.
Section 39: Restoration of Lapsed Patents
"Where a patent has ceased to have effect by reason of a failure to pay any renewal fee, an application for the restoration of the patent may be made to the Registrar within the prescribed period." — Section 39(1)
Verify Section 39 in source document →
Section 39 permits patentees to apply for restoration of patents that have lapsed due to non-payment of renewal fees, subject to prescribed conditions. The rationale includes:
- Mitigating inadvertent lapses: Recognises that failure to pay fees may be unintentional and allows patentees a second chance to maintain protection.
- Preserving patent rights: Prevents permanent loss of rights due to procedural oversights, supporting innovation incentives.
- Ensuring procedural fairness: The prescribed period and application process provide a structured and equitable approach to restoration.
This provision balances administrative efficiency with fairness to patentees.
Section 40: Surrender of Patents
"The proprietor of a patent may at any time by notice given to the Registrar offer to surrender the proprietor’s patent." — Section 40(1)
Verify Section 40 in source document →
Section 40 allows patentees to voluntarily surrender their patents at any time. The purposes are:
- Providing flexibility: Enables patentees to relinquish rights if the patent is no longer commercially valuable or strategically necessary.
- Clarifying legal status: Formal surrender removes uncertainty about the patent’s enforceability and availability for public use.
- Facilitating public access: Surrendered patents enter the public domain, promoting wider use and innovation.
Section 40(2) further clarifies that no compensation arises for use of the invention before the surrender date in accordance with Section 56, ensuring legal certainty for users.
Cross-References and Their Significance
The provisions in Part 7 frequently cross-reference other sections and related legislation, reflecting the interconnected nature of patent law. For example:
- Section 38A(1)(c)(ii) references section 20(3), 47(4), 116(6) of the Patents Act (Cap. 221, 1995 Revised Edition) and section 26(11), linking re-examination grounds to priority claims and application procedures.
- Section 36(1) refers to Section 36A, integrating term extensions into the duration framework.
- Section 38(1) is subject to Section 84, which governs further conditions on amendments.
- Section 40(2) references Section 56, clarifying compensation rights upon surrender.
These cross-references ensure coherence and consistency across the patent regime, facilitating comprehensive legal interpretation and application.
Conclusion
Part 7 of the Patents Act 1994 provides a robust legal framework governing the lifecycle of patents in Singapore. The provisions analysed serve to:
- Ensure timely and transparent communication of patent grants (Section 35).
- Define clear terms of protection while accommodating extensions for delays and regulatory hurdles (Sections 36 and 36A).
- Limit procedural objections to promote patent stability (Section 37).
- Allow controlled amendments and post-grant re-examination to maintain patent quality (Sections 38 and 38A).
- Provide mechanisms for restoration of lapsed patents and voluntary surrender (Sections 39 and 40).
Collectively, these provisions balance the interests of patentees, third parties, and the public, fostering an effective and fair patent system that encourages innovation and economic growth.
