The Power of Curiosity: How Chien-Yi Tsai Turned an Idea into a Patent at Coupa

Chien-Yi Tsai’s career hasn’t followed a straight line, and that’s exactly what led him to innovation.
Looking back, Chien-Yi doesn’t see a single defining moment that made him an inventor. Instead, he sees a series of questions, challenges, and moments of curiosity that gradually shaped him into the engineer he is today. His focus was never on earning a patent, but on continuous learning, solving meaningful problems, and pushing beyond what felt comfortable.
“I never set out with the goal of becoming a patent inventor,” Chien-Yi shares. “I was focused on learning, solving real problems, and pushing myself beyond what felt comfortable.”
That mindset ultimately led him to Coupa, and to invention.
A Career Built on Curiosity
Like many engineers, Chien-Yi’s early career was about building strong foundations: understanding how systems work, weighing technical tradeoffs, and learning how technology can solve real business challenges. Each role added depth such as stronger technical skills, broader systems thinking, and a growing appreciation for collaboration.
When Chien-Yi joined Coupa, he entered an environment that actively encouraged curiosity. The challenges weren’t neatly packaged; they were complex, evolving, and deeply connected to real-world supply chain operations. That complexity pushed him to think bigger and approach problems more creatively.
Before Coupa, Chien-Yi didn’t consider himself an “inventor.” He saw himself as a problem solver. Over time, he realized the distinction wasn’t as clear as he once thought.
“I didn’t think of myself as an inventor but more of a problem solver,” he says. “Over time, I realized those two things aren’t very different.”
The Spark Behind the Patent
The idea that eventually became a patent began with a simple question: How can supply chains become smarter, faster, and more efficient as new delivery methods emerge?
As delivery models continue to evolve, Chien-Yi became increasingly interested in how emerging transportation capabilities could be thoughtfully integrated with traditional logistics networks. That curiosity led to deeper exploration of how different modes of delivery could operate together within a single system.
As Chien-Yi thought more about the increasing viability of drones, it became clear to him that they could play a meaningful role in logistics. But integrating aerial delivery with traditional ground transportation introduced an entirely new layer of complexity.
What started as informal conversations and rough concepts evolved into a structured exploration of how to model routes that intelligently combine aerial and ground delivery assets, accounting for capabilities, constraints, and user preferences. The challenge wasn’t just technical; it required rethinking how multiple transportation modes could operate as one unified system.
Chien-Yi credits his colleague at the time, Hafiz Hasan, as a key partner in the ideation and patenting process.
“Hafiz played a major role in shaping the idea and writing the patent,” Chien-Yi notes. “I learned a tremendous amount from working with him.”

The Reality of the Patent Journey
Turning an idea into a patent proved to be a marathon, not a sprint.
The process demanded deep research, precision in language, and relentless iteration. Every assumption had to be challenged. Every detail mattered. It pushed Chien-Yi beyond the scope of his day-to-day engineering work and forced him to articulate and defend innovation with clarity and rigor.
There were moments when the process felt daunting, but those moments also drove growth.
“Every assumption had to be questioned,” Chien-Yi reflects. “That’s where the real learning happened.”
Seeing the work culminate in U.S. Patent No. 12481936: Supply Chain Route Modeling with Unmanned Aerial Vehicle Segments was deeply meaningful, not just as a technical achievement, but as a reflection of how far he had come in his career.
Redefining What Innovation Looks Like
The experience reshaped how Chien-Yi views innovation and his role as an engineer. Innovation, he believes, isn’t reserved for specific titles or career stages. It happens where curiosity meets opportunity.
Coupa played a critical role by providing the space, support, and belief that employee-driven innovation matters.
“You don’t need to have everything figured out to start,” Chien-Yi says. “Ask questions. Get involved. Learn from the process.”
For those at Coupa wondering whether an idea is “worth pursuing,” his advice is simple: explore it.
“You never know where it might lead—whether in your career or in shaping the future of the platform.”
Looking Ahead
Innovation at Coupa doesn’t happen in isolation. It’s driven by teams of curious thinkers who are encouraged to challenge assumptions, explore ideas, and grow their careers along the way.
For engineers excited by complex problem-solving and by the possibility that an idea could one day turn into real-world impact, even a patent, Coupa offers a place to do just that.
