About “Liu Ding” (柳丁)
Ludin IP is named after liu ding (柳丁) — the orange. In many cultures, the orange is a symbol of vitality and the “sweet reward” of years of hard work.
Like an orange, innovation is a seed that requires the right soil and a resilient structure to bear fruit. At Ludin, we provide the strategic environment your ideas need to thrive. We believe that a well-protected invention is the “fruit” of your labor, and we are here to ensure that fruit is secured.
How We Secure Your Future:
🟠 Patents: Protecting deep-tech innovations (AI, Software, Electronics, Mechanical).
🟠 Registered Design: Protecting the visual DNA and “look and feel” of your products.
🟠 Trademarks: Securing your brand identity in Singapore and abroad.
🟠 IP Roadmap: Aligning your portfolio with your business exit or scaling goals
Precision of a Patent Attorney. Insight of an Engineer.
I am Liu Da Rong, a Singapore-qualified patent attorney and the founder of Ludin IP.
With over 18 years of experience—ranging from high-stakes private practice to serving as In-house Counsel for a global innovation leader—I bridge the gap between complex technical innovation and strategic legal protection.
I founded Ludin IP to provide tech founders and startups with an agile, personal alternative to the traditional firm model. When you work with us, you aren’t handed off to a junior associate; you work directly with me to ensure your “tech moat” is built on a foundation of engineering fluency and legal precision.
The Engineer-Attorney Advantage
With a professional background in Electronic Engineering, I don’t just read your disclosures; I understand the circuitry, the signal processing, and the algorithmic logic behind them. Whether your invention involves Artificial Intelligence, Electronics, or Mechanical Systems, our conversations start at a technical level.
Because I speak your language, I can draft patents that are technically accurate and legally strong. I focus on capturing the “heart” of your invention so your protection is solid enough to stop competitors, but clear enough to pass through the patent office without unnecessary delays.
A Commercial Perspective
My tenure as In-house Counsel gave me a unique “front-row seat” to how IP drives real-world commercial value. I understand that a patent isn’t just a legal certificate to hang on a wall; it’s a strategic business tool. I apply that same high-stakes corporate rigor to every startup and SME I work with, focusing on Freedom to Operate (FTO) and building intellectual property that actually deters competitors.
At Ludin IP, I am your lead strategist. You won’t be handed off to a junior associate once the engagement starts. You get the benefit of nearly two decades of experience—from leading private practices to global innovation hubs—applied directly to your portfolio.
