ROI Calculation Logic

High-precision force calculation could shorten surgery times and reduce re-operation risks. For example, a 10% reduction in average surgery time, assuming an average cost of ~$3,350 (AI est.) per surgery at a hospital performing 1,000 surgeries annually, could yield ~$350K/year in cost savings. Reduced training periods for surgeons also contribute to labor cost savings.

Speed to Market
6× faster than in-house development
Developing a similar force calculation technology for medical devices in-house could take at least 3 years, covering proof-of-concept, prototype development, safety evaluation, and clinical trials. However, this technology's components (measured part, measuring part, calculation part) and operating principles are already clearly defined and established within the patent. This allows licensees to significantly shorten basic research and initial development phases, focusing instead on integration into existing systems and compatibility verification, making market entry in approximately 6 months highly feasible.
