Jon graduated from Singapore Management University with a LL.B. degree (Cum Laude) in 2016, and was called to the Singapore Bar in mid-2017. Jon practises in all aspects of intellectual property law and has advised and acted for clients from a range of industries such as luxury brands, pharmaceuticals, information technology, and solar energy. In particular, Jon has an active litigation practice and has acted in a number of notable cases before the Court of Appeal, the High Court and various tribunals, which dealt with novel issues relating to both substantive and procedural intellectual property law.

Jon has acted as lead counsel in the following reported cases:

1. Fonterra Brands (Singapore) Pte. Ltd. v Consorzio del Formaggio Parmigiano Reggiano [2024] 2 SLR 624 (CA) – This case is the first qualification of rights action under the Geographical Indications Act 2014 to be heard by the Singapore Courts and centred on the novel issue of how a “translation” of a geographical indication is determined. This matter was litigated to the Court of Appeal where Jon successfully acted for the appellant in reversing the High Court’s decision below. Due to the novelty and complexity of the issues involved, the Court of Appeal also appointed an Independent Counsel to assist the Court in the appeal.
2. Consorzio di Tutela della Denominazione di Origine Controllata Prosecco v Australian Grape and Wine Incorporated [2023] 2 SLR 509 (CA) – This case is the first geographical indication opposition matter to reach the Singapore Courts and was heard and decided by a five-judge panel of the Court of Appeal. Due to the novelty and complexity of the issues involved, an Independent Counsel was also appointed to assist the Court. This is the first case in which the Court of Appeal considered the provisions of the Geographical Indications Act 2014 and the concept of geographical indications.
3. Louis Vuitton Malletier v Ng Hoe Seng (formerly trading as EMCASE SG) [2025] SGHC 122 – This is the first case to substantively examine the meaning of a "counterfeit trade mark" under the Trade Marks Act 1998 as well as the applicable statutory damages limits prescribed under said Act. In addition, the High Court considered a wide range of authorities from Singapore, Canada, US, Australia and UK in quantifying the statutory damages to be awarded to the claimant.
4. L’Oreal and another v Shopee Singapore Pte Ltd [2025] SGHCR 2 – This case dealt with the interesting procedural issues of whether the principles on interrogatories under the old civil procedural regime still apply to applications for pre-action production of information under the present civil procedural regime and the relevant test in assessing the sufficiency of responses to an information production order.
5. Sun Electric Pte Ltd v Sunseap Group Pte Ltd and others and another suit [2019] SGHCR 11 – This decision dealt with the interesting situation of a procedural impasse between the parties: the alleged patent infringers had requested the patent proprietor for further and better particulars of the infringement claim but the patent proprietor takes the position that the requested particulars can only be provided after the alleged infringers have responded to its interrogatories to provide information on the alleged infringers’ processes. The High Court gave guidance on the approach in overcoming this impasse.
6. Google LLC v Green Radar (Singapore) Pte Ltd [2024] SGIPOS 1 – Jon successfully represented the applicant of the “grMail” trade mark in overcoming an opposition commenced by tech giant Google which asserted its earlier “GMAIL” trade mark. Although the Hearing Officer found that Google’s “GMAIL” trade mark was well known to the public at large, which confers on a much higher degree of protection to the mark, the Hearing Officer found that there was no unfair dilution or taking of unfair advantage by the applicant.
