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. 

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.
