Public feedback is invited on proposed amendments to Regulation 23 of the Health Products (Therapeutic Products) Regulations (“TPR”) on patent declaration. The public consultation runs from March 1 to March 31, 2024. The consultation document and draft legislation are available on the HSA website (


Under Regulation 23 of the TPR, the HSA must consider whether a patent under the Patents Act 1994 is in force in respect of the therapeutic product undergoing registration application.

The applicant seeking to register a therapeutic product is required to make and furnish a patent declaration to the HSA, and notify the patent proprietor if a registration application for a therapeutic product that is subject to a patent is made during the patent term without the consent or acquiescence of the proprietor.

The legislative mechanism was implemented to fulfil Singapore’s obligation under the US-Singapore Free Trade Agreement. It seeks to facilitate timely resolution of any potential patent disputes prior to the HSA’s granting of registration for a therapeutic product. 


The proposed amendments aim to:

  1. Provide clarity to industry stakeholders on the types of patents that must be considered when making a registration application for a therapeutic product, and for which the provisions under Regulation 23 apply.
  2. Ensure a system that facilitates all industry stakeholders in making registration applications and minimises any potential indiscriminate use of the mechanism under Regulation 23.

Key proposed legislative changes

Regulation 23 will be amended to apply to the following categories of patents that are in force in respect of the therapeutic product undergoing registration application:

  1. a patent containing a claim for an active ingredient of that therapeutic product;
  2. a patent containing a claim for a formulation or composition of that therapeutic product;
  3. a patent containing a claim for the use of an active ingredient in the manufacture of that therapeutic product for a specific therapeutic, preventive, palliative or diagnostic use.

Patents that are in force in respect of the therapeutic product but do not fall under the abovementioned categories are not subject to the requirements under Regulation 23.

Regulations 24 and 25 will be updated to reflect the jurisdiction under which patent infringement matters reside and clarify the offences related to making a false declaration, respectively.
