Latest / The Founder's Journey with Fexingo: First-Time Entrepreneurs, Failures, and Lessons Learned / The Founder Who Turned a Rejected Patent Into a 60M Licensing Business
Transcript
- Lucas: So you've heard the stories where a founder takes a rejected product and builds a whole business around it. But what if the product itself isn't even a physical thing — it's an idea, a patent that someone else said no to? Luna: That's a much harder sell. You're basically walking into a room and saying, 'Hey, I have this piece of intellectual property that my last employer didn't want, but I think you should pay me for it.' Lucas: Right. And that's exactly what Sarah Chen did. She was a chemical engineer at a large industrial cleaning supply company. In 2017, she filed a patent for a biodegradable solvent that could replace harsh chemicals in degreasing operations. Her employer reviewed it and said — not interested. Luna: Did they let her keep the patent? Lucas: That's the critical detail. Her employment contract had a clause that any invention made on company time or with company resources belonged to them. But here's the thing — she had filed the patent on weekends, using her own lab equipment at a university shared facility. So after some legal back and forth, the company agreed to assign the patent to her. They just didn't see any commercial value in it. Luna: That's a huge risk for her. She's now holding a patent with no product, no customers, and presumably no income. Lucas: Exactly. She had a patent and a vision. She believed this solvent could replace toxic chemicals in industrial cleaning — things like degreasing engine parts or cleaning printing presses. So she started cold-emailing contract manufacturers and industrial cleaning companies. She didn't have a product to sell; she had a license to offer. Luna: And someone bit? Lucas: The first bite came from a mid-size industrial cleaning outfit in Ohio. They specialized in cleaning food-processing equipment, and they were under pressure from their clients to go green. Sarah offered them an exclusive license for the food industry in exchange for a five percent royalty on sales. They said yes in 2018. Luna: Five percent — that's actually low for a licensing deal, right? I've seen numbers like ten to fifteen percent for early-stage tech. Lucas: You're right, but she was unproven. She needed that first win. The key was that she structured the deal with a minimum annual royalty — fifty thousand dollars. So even if they didn't sell much, she had a floor. And it turned out they sold a lot. Within two years, that one licensee was paying her over two hundred thousand dollars annually. Luna: That's a great anchor. It also gave her credibility to approach other industries. Lucas: Exactly. She used that first deal as a reference to license the patent to other sectors — aerospace, automotive, marine. By 2022, she had twenty licensees across five industries. Her company, ChemFree Innovations, was generating about 60 million dollars in annual revenue — all from licensing. She never manufactured a single bottle herself. Luna: So the entire business model is just IP management. No factories, no supply chain, no inventory risk. Lucas: Right. Her costs were legal fees for patent maintenance, some marketing, and a small team of two licensing managers. Her margins were north of eighty percent. The beauty of the licensing model is that you're essentially renting your idea to people who already have the infrastructure to produce and sell it. Luna: But why did the original employer pass? They had the infrastructure. They could have made millions. Lucas: That's the part that still baffles her. She told me in an interview that her former boss said the solvent was 'too niche' and 'the market for green industrial cleaners is too small.' That was in 2017. By 2023, the global green cleaning chemicals market was over 4 billion dollars. They completely misread the trend. Luna: They saw the short-term cost of reformulating their product line and said no. She saw a long-term shift. Lucas: Exactly. And she bet on the fact that regulation would eventually push companies toward greener alternatives. That's starting to happen — the EPA has been tightening rules on volatile organic compounds, and her solvent qualifies as voc free. Luna: So what's the lesson for someone listening who might have a rejected patent sitting in a drawer? Lucas: First, make sure you actually own the IP. Sarah's situation was unusual — most employers will fight to keep inventions. She was lucky that her company saw no value. But second, don't try to build a product if you don't have to. Licensing lets you focus on what you do best — inventing — and lets others handle manufacturing and distribution. Luna: And third, start with a single licensee in a specific vertical. Get that case study, then expand. Lucas: Yeah. She told me that if she had tried to license to everyone at once, she would have spread herself too thin. By focusing on food processing first, she learned everything about that industry's needs, regulations, and buying cycles. That made her pitch to aerospace much stronger. Luna: It's also a reminder that rejection from an employer isn't always a signal that your idea is bad. It might just mean the company's incentives are misaligned. Lucas: Right. Her former employer's core business was selling high-margin chemical solvents. A biodegradable alternative would have cannibalized their own sales. They had no incentive to adopt it. But as a standalone licensing business, it thrived. Luna: That's a really important nuance. Sometimes the people who say no are the ones who would lose the most if you succeeded. Lucas: Exactly. And speaking of success — you know, if you're finding value in these stories, it's worth mentioning that we're able to keep this show ad-free thanks entirely to listener support. People who chip in at buy me a coffee dot com slash fexingo help us keep the lights on and the interviews coming. Luna: Yeah, it's a small gesture that makes a big difference. And we really appreciate it. Lucas: So back to Sarah — she's now working on her second patent, a biodegradable coating for food packaging. And she's using the same strategy: license it to packaging manufacturers rather than building her own production line. She expects to have her first deal signed by the end of this year. Luna: I love that she's doubling down on what worked. It's a playbook now. Lucas: It is. And it's a reminder that sometimes the best business is the one where you never actually make the product yourself. You just own the idea and let others do the heavy lifting. Luna: That's the dream, right? Minimal capital, maximum leverage. Lucas: For Sarah Chen, that dream started with a rejected patent and a few cold emails. And now it's a 60 million dollar licensing business.
