ROI Calculation Logic

Traditional mRNA dynamics analysis methods (e.g., FISH, RT-qPCR with fixation/staining) are time-consuming and costly. This technology enables real-time observation in live cells, significantly simplifying and accelerating experimental processes. For a project with an annual research budget of ~$330K (AI est.), assuming a ~30% reduction in experimental labor and ~10% reduction in reagent costs across three such projects, this could contribute to an annual R&D cost reduction of ~$1M (AI est.) ($330K × 3 projects × 10% + $330K × 3 projects × 30%). This could shorten the R&D cycle by up to 20%.

Speed to Market
4× faster than in-house development
This technology's fundamental molecular design and fluorescence generation mechanism have already been established by the Japan Science and Technology Agency (JST). This significantly reduces the extensive time and cost a licensee would incur developing similar technology from scratch, covering molecular design, synthesis, and evaluation. Since a patented solution for the complex challenge of live-cell mRNA visualization already exists, licensees can rapidly transition to the application development phase, substantially accelerating time-to-market and securing first-mover advantage.
