Research & IP

The science, patents, and strategy behind our breakthrough wave energy technology.
Dual Protection IP Strategy
Atargis protects the CycWEC through a combination of patents and proprietary software. Eighteen patents cover its core hardware, deployment methods, and energy capture systems. The control algorithms and simulation code remain undisclosed, enabling energy capture efficiencies of up to 95%. This dual protection creates a durable competitive edge, safeguards operational reliability, and minimizes the risk of imitation.
