ROI Calculation Logic

In smart factories, assuming an average of 100 hours of annual production downtime due to communication failures causing data collection interruptions, with an opportunity cost of $10,000/hour (AI est.). By reducing this downtime by 10% with this technology, an annual loss of 10 hours ($10,000/hour × 10 hours = $100K) can be avoided. Scaling this across multiple facilities could yield an estimated annual opportunity loss reduction of ~$1.0M (AI est.).

Speed to Market
6× faster than in-house development
Developing this technology from scratch in-house, including complex control algorithms for multiple communication protocols and automatic path switching, could take approximately 3 years. However, by licensing this patent, companies can leverage established technical concepts and protected intellectual property, moving directly to the implementation phase. This could shorten the development timeline by about 2.5 years, enabling market entry in approximately 6 months. This provides a significant first-mover advantage in deploying high-reliability communication solutions.
