SHELTON, CONN.—Budderfly, one of the fastest growing energy companies in the U.S., announced a record pace of innovation, with 21 patents filed and 4 patents granted in 2025—the highest annual filing total in the company’s history. Budderfly’s portfolio now stands at 34 granted patents, 2 allowed patents, and 34 pending patent applications. This milestone expands Budderfly’s proprietary systems and reinforces its leadership in distributed energy optimization.
Budderfly’s portfolio spans advanced HVAC control methods, distributed energy coordination systems, intelligent load balancing, and behind-the-meter microgrid controls. These technologies operate within Budderfly’s integrated platform, which combines capital investment, proprietary software, energy baselining, billing infrastructure, and continuous performance management. Together, they enable Budderfly to orchestrate and optimize energy performance across thousands of commercial facilities nationwide.
Budderfly also holds patents protecting its unique expense-takeover model, the operational foundation of its Energy-as-a-Service platform. These include both process and technology patents that enable Budderfly to finance, deploy, and manage energy infrastructure while aligning long-term performance with customer cost savings.
Eye on Continuous Improvement
“Innovation is built into our model,” said Al Subbloie, CEO of Budderfly. “Because we invest our own capital and deploy the infrastructure, we’re constantly pushing the system to perform better—lower energy use, stronger reliability, and smarter portfolio performance. Operating at scale across thousands of facilities accelerates that learning. These patents are the result of that discipline.”
Budderfly’s expanding IP portfolio reflects innovations developed through years of system design, engineering research, and large-scale deployment. New technologies are evaluated, refined, and piloted before being deployed broadly. The result is a continuous cycle of innovation that strengthens system performance while expanding Budderfly’s proprietary technology platform.
“Our inventors come from across the organization, including installers, engineers, product teams, and even executives,” said Jaan Leemet, Intellectual Property Specialist at Budderfly. “Innovation isn’t isolated here. Through our inventor program, ideas emerging from the field or the lab are identified, refined, and protected. That’s how we turn scaled deployment into a durable competitive advantage.”
This record-breaking year highlights Budderfly’s commitment to innovation as a core component of its strategy, strengthening market differentiation, driving measurable customer impact, and reinforcing long-term value for customers, investors, and partners.
