Intellectual
Property

Being a network of the oldest and largest IP practices in the region, we have decades of experience helping our clients protect and extract value from their trademarks, patents, industrial designs, plant varieties, circuits, copyright, domain names and trade secrets.  Our tier one multi-award winning teams are regularly retained by the largest MNCs, Fortune 500 companies, state-owned organisations, financial institutions, SMEs and start-ups from a diverse range of industries.

Our teams comprise an IP adjudicator appointed by the IP Office of Singapore (IPOS) to hear disputes, certified patent valuation specialists, an expert panellist appointed by the World Intellectual Property Office (WIPO), a Fellow of the Singapore Institute of Arbitrators (SiArb) and more than 200 locally and overseas qualified patent attorneys, advocates and solicitors, executives and support staff that have remained at the forefront of technology with the ability to prosecute, manage and enforce our clients’ highly technical and complex intellectual property assets including those involving Life Sciences, Fintech, Biotech, AI, engineering (computer, electrical, mechanical, aeronautical, chemical), chemistry and blockchain.

We provide the full range of services, from pre-filing advisory and freedom-to-operate searches, clearance, drafting, filing, prosecution, maintenance as well as analysing and reviewing our clients’ portfolios, advising on monetising and licensing options as well as guiding our clients in the valuation of all their intellectual property assets.

We are well-versed in helping clients navigate local and cross-border commercial transactions and regulatory approval processes which involve IP, IT and competition law. These include franchising, acquisitions, asset transfers and regulatory approvals in various industries including pharmaceutical, entertainment, telecommunication, media and gaming.

Enforcement is another strong suit for all the IP teams in our network. Our top-notch litigation teams are the first port of call for clients involved in IP disputes and are repeatedly picked to tackle the most complex, high-valued and precedent setting IP disputes at all levels of the Courts and Registries.

Our clients trust us to handle all aspects of IP litigation from executing warrants for infringement offences, defending criminal actions for infringement, applications for urgent injunctions and search orders, passing off actions, opposition, invalidation and revocation proceedings, infringement and actions for breach of licensing/distribution/franchising agreements as well as breach of confidentiality obligations.  

We also proactively assist clients in protecting and enforcing their rights against counterfeiting, piracy and infringement including crafting enforcement strategies by work closely with Customs and other relevant authorities in our respective jurisdictions as well as conduct regular market surveys, online market monitoring and raids to facilitate and ensure prompt seizure of counterfeits. 

Our win-rate and undeniable expertise has allowed each of our teams to be consistently singled out by clients and prominent trade publications. In a world where technology is constantly evolving, what defines the core of our IP practice is our ability to quickly understand the technicalities of each industry and deliver swift, practical and quality advice to meet the clients’ business objectives in a cost effective manner.
