Patent Prosecution and Ex Parte Proceedings at the Intellectual Property Office of Singapore by Tony Yeo, Yvonne Tang, Lim Siau Wen, Drew & Napier LLC Practice notes | Law stated as of 01-May-2023 | Singapore A Practice Note on the key aspects of patent application filing, prosecution, and related ex parte proceedings atthe Intellectual Property Office of Singapore (IPOS) . This Note provides an overview of the Singapore patent application filing and examination process. It also addresses strategic considerations for the patent applicant. Innovative multinational companies typically seek to protect their inventions and obtain freedom to operate globally. Depending on their global manufacturing and supply chain footprint, customer location, and competitive threat outside of their home country, these companies may encounter both patent protection and freedom to operate issues in countries with robust economies, such as Singapore. However, patent application filing and examination procedures in the Intellectual Property Office of Singapore (IPOS) can be challenging, especially for parties based outside of Singapore. Although parties typically retain local Singapore patent counsel to address patent issues in Singapore, even with expert local patent counsel, non-Singapore entities may still find patent application filing and examination procedures at the IPOS confusing, time consuming, and expensive. This may make it especially hard to properly evaluate the value of Singapore patent protection, address the intricacies of Singapore patent practice, and ensure robust patent protection in Singapore. This Note addresses patent practice at the IPOS and addresses important considerations for counsel for the patentee, including key strategic factors, timing issues, and explanation ofIPOS patent procedures. Patent Registration at the IPOS The only type of patent protection available through the IPOS is invention patent protection. There is no utility model protection in Singapore, and design rights are separately termed and protected as “registered designs” under the Registered Designs Act 2000. For an invention to be patentable, it must be novel, involve an inventive step, and be capable of industrial application (section 13, Patents Act). Since claims directed to a method of treatment of the human or animal body by surgery or therapy, or of diagnosis practised on the human or animal body are not capable of industrial application in Singapore, they are not permitted (section 16, Patents Act). However, claims directed to computer-implemented inventions may be patentable if it is established that the computer (or other technical features), as defined in the claims, is integral to the invention for the actual contribution to comprise the computer (or technical features). For example, claims relating to a computer-implemented business method would be considered an invention if the various technical features (for example, servers, databases, or user devices) interact with the steps of the business method: • To a material extent. • In a manner that addresses a specific problem. If the technical features recited in the claim are no more than the workings of a standard operating system, particularly the use of a generic computer or computer system to perform a pure business method, this interaction would not be considered material, and no specific problem would be solved. The actual contribution is likely to be the business method, and the claimed subject matter would not be considered an “invention” by merely including the term “computer-implemented” or a similar generic term in the claims (section 8.6 and 8.7, IPOS Examination Guidelines). Inventions that may encourage offensive, immoral, or anti-social behaviour will not be published and are not patentable (section 13, Patents Act). A patent allows an exclusive right to the invention and prevents others from exploiting the invention without permission. Once gran

FAQs

What patent types are available through the IPOS?

The IPOS provides invention patent protection. Singapore does not offer utility model protection, and design rights are protected separately as registered designs under the Registered Designs Act 2000.

What makes an invention patentable in Singapore?

An invention must be novel, involve an inventive step, and be capable of industrial application. Claims to methods of treatment or diagnosis practiced on the human or animal body are not capable of industrial application and are not permitted.

How are computer-implemented inventions assessed for patentability?

Claims to computer-implemented inventions may be patentable if the computer (or other technical features) is integral to the invention’s actual contribution. Interaction with servers, databases, or user devices can support an invention if it addresses a specific problem, while generic use of a computer to perform a pure business method is typically insufficient.
