ROI Calculation Logic

Assuming a domestic foot care market for corn-related treatments and products of ~$650M/year (AI est.). This technology could reduce the frequency of professional visits and OTC product purchases by 10%. Based on market penetration and licensee share (1.5%), the estimated annual savings are ~$650M (AI est.) × 10% × 1.5% = ~$1.0M/year (AI est.).

Speed to Market
5× faster than in-house development
This technology has completed prototyping and basic structural validation. The tweezers-like structure described in the claims can be easily mass-produced using existing metal processing and precision component manufacturing lines. It does not require complex electronic controls or special materials, significantly shortening the development period and reducing time-to-market by an estimated 2 years.
