ROI Calculation Logic

If a company conducts ~100 tests annually, a 20% reduction in test period could save $20K (AI est.) directly from personnel ($40K/person, AI est.) and equipment operating costs ($65K/year, AI est.). Including re-testing reduction and faster market entry, total indirect cost savings could exceed $200K (AI est.) annually.

Speed to Market
6× faster than in-house development
This technology addresses long-standing challenges in creep testing, such as discontinuous load control and large equipment size, with a unique linear mechanism. Developing an equivalent technology from scratch in-house would require at least 3 years for mechanical design, control algorithm development, precision component selection/manufacturing, and validation testing. However, by licensing this patent, companies can leverage an established technical concept and basic mechanism, with its patent grant confirming technical feasibility. This allows licensees to focus on optimizing and implementing the test apparatus, potentially shortening time-to-market to approximately 6 months.
