Practice Areas  

Dispute Resolution

We are at the forefront of life sciences intellectual property disputes in Singapore. We have successfully represented the world-famous Institut Pasteur, Sanofi and Biorad in enforcing the patent for the HIV-2 virus and diagnostic kits to detect the HIV-2 virus in a ground breaking patent case in Singapore. The Singapore Court of Appeal ruled in favour of the patent owners and dismissed the appeals (See the reported decisions at Institut Pasteur & Anor v Genelabs Diagnostics Pte Ltd & Anor [2000] SGHC 53 and Genelabs Diagnostics Pte Ltd v Institut Pasteur and Another [2001] 1 SLR 121).

We have also successfully represented Novartis AG and Novartis (Singapore) Pte Ltd (“Novartis”) in their application to amend a Patent, post-grant, under section 83 of the Singapore Patents Act. This application to amend was made after Novartis started a suit for patent infringement against Ranbaxy (Malaysia) Sdn Bhd. This is the first reported Singapore case in which the hearing for the patent amendment was heard separately from the main infringement and invalidation hearing. The Singapore High Court found that the proposed amendments did not “add matter” to the Patent, and also that there was no undue delay on the part of Novartis in applying to amend the Patent in Singapore and granted the amendment. (See the reported decision at Novartis AG and Novartis (Singapore) Pte Ltd v Ranbaxy (Malaysia) Sdn Bhd [2012] SGHC 253).

We also represented Becton Dickinson against B.Braun in a patent infringement actiont involving medical devices in Suit 655/2018. This was a multi-jurisdictional action involving proceedings in Singapore, the UK and New Zealand.

We further represented Novartis AG and Novartis (Singapore) Pte Ltd in a novel patent infringement in Singapore in Suit 1062/2019. This matter concerns a product licence for generic medicinal product for the treatment of, inter alia, chronic myeloid leukaemia. The outcome of the suit may have an effect on way public hospitals, pharmacies and oncologists prescribe and purchase medicinal products.

The Practice has also represented Novartis and sanofi-aventis in the following matters:

  • Novartis in Suit 150/2011/R and 1085/2012/G in a patent infringement action involving an invention relating to drugs for treatment of high blood pressure

  • sanofi aventis in Suit 305/2010/Y for alleged infringement of patents in the treatment of breast cancer

  • sanofi aventis in Originating Summons No. 991/2011/L for a determination under Section 16(1B)(c) of the Medicines Act (Cap 176) on issues concerning patent declarations by a generic company

Corporate Commercial and Regulatory

The Practice has expertise and strength in all corporate, commercial and regulatory matters. We have advised many pharmaceutical, life sciences, biotechnology, health care, and food and beverage companies.

These include:

  • Advising on labelling, advertising, as well as sales and promotion regulations for the pharmaceutical, medical devices, and the food and beverage industries

  • Advised a healthcare institution in relation to compliance with medical laws and regulations on promotional programmes

  • Reviewing and drafting clinical trial agreements, research and development agreements, licensing agreements, franchise agreements, funding agreements

  • Advising on all aspects of employments and other regulatory matters, including employment agreements, secondment arrangements, and termination of employees

  • Assisting in the due diligence, negotiations and acquisitions of pharmaceutical products and companies, hospitals and health care institutions.

Some of the matters handled include:

  • Acted for a European based pharmaceutical manufacturer in a high-stakes Exclusive Licence Agreement where the client would acquire worldwide exclusive rights to a pre-clinical platform developed by a Singapore based company. The expected earnout payments in upfront and success-based development and commercialisation milestones are expected to be more than US$1 billion.

  • ​Acted for Lucence Diagnostics in relation to its Series A funding round, which raised US$20 million. The funding round was led by Parkway Holdings Limited, which was coming in as a strategic investor, and was looking to, among others, co-develop solutions with Lucence. The Lucence group, which has offices in the US, Hong Kong and China, develops liquid biopsy tests to detect cancer early and improve treatment selection.

  • Acted for a healthcare-focused equity investment firm’s joint venture with an international private equity firm to invest up to S$20 million in a global medical healthcare group. This includes performing legal due diligence and advising on transactional documents. 

  • Acted for and advised the purchaser in the 100% sale of a leading supplier of multiplexed molecular diagnostic solutions. Under challenging timeframes, we conducted legal due diligence on the target company, and also assisted in the review and preparation of the transaction documentation, including the sale and purchase agreement. We also provided legal advice and assistance under Singapore laws on the transaction and also coordinated and liaised with lead counsel and with clients in Japan. The Sellers also included a French shareholder as part of the sellers’ consortium.
