What This Patent Covers

This patent protects a robust system combining location information, acoustic data, machine learning-based determination, and wireless signal reception. With limited prior art and strong claims, it offers a significant technological advantage for early market share acquisition. The patent is maintained until 2041, providing a long-term foundation for business development.

Competitive White Space

This patent primarily covers buoy-based acoustic and wake detection for suspicious vessels. White space exists in integrating advanced visual or radar-based detection systems, developing predictive behavioral analytics, or implementing autonomous response mechanisms.

Economic Impact
~$1.0M/year estimated poaching damage reduction and ~$50K/year in personnel cost savings per facility (est.).
estimated ROI · USD · AI analysis
ROI Calculation Logic

Based on Fisheries Agency data, annual poaching damage is estimated to be several hundred million JPY. If this system improves poaching detection rates by 50%, an annual reduction of ~$1.0M (AI est.) is expected (calculated as ~$2.0M annual damage × 50%). Furthermore, assuming a 20% reduction in annual personnel costs for 5 surveillance staff (total ~$200K/year), an additional ~$50K (AI est.) in annual labor cost savings could be achieved.

Speed to Market
8× faster than in-house development
This technology's core elements, including buoy-based location and wake pattern detection, microphone-based acoustic data acquisition, and machine learning for acoustic fingerprinting, are already patented and conceptually proven. These algorithms can be integrated with existing IoT sensors and communication modules, enabling rapid system construction and validation. This significantly shortens development time compared to starting from scratch.
