IP Defensibility — Why Competitors Can't Replicate This
What This Patent Covers

This patent, held by the University of Tokyo, covers an apparatus and method for glass polishing using abrasive-free pure or pH-adjusted water. It protects the core mechanism of supplying a non-abrasive processing fluid between an acrylic tool and a glass workpiece during relative motion. The claims are considered robust, having successfully overcome two office actions, indicating strong novelty and inventiveness.

Competitive White Space

This patent primarily covers the apparatus and method for abrasive-free glass polishing. White space exists in advanced real-time process monitoring, AI-driven quality control systems, or adapting the core principle to non-glass transparent materials.

ROI Calculation Logic

A typical glass polishing line incurs ~$350K/year (AI est.) in abrasive purchase costs and ~$200K/year (AI est.) in waste fluid treatment expenses. This technology could eliminate nearly 90% of these costs, resulting in ~$495K in savings. Additionally, it could reduce annual labor costs for post-processing cleanup (estimated at ~$50K/year for two operators) by ~50%, saving ~$25K. This leads to total annual savings of ~$520K (AI est.) per facility.

Speed to Market
4× faster than in-house development
This technology utilizes readily available materials like acrylic tools and pure/pH-adjusted water. It can likely be integrated into existing polishing systems by adding processing fluid supply and relative motion mechanisms. As an invention from a national university, foundational empirical data and principles are presumed established, significantly shortening deployment compared to greenfield R&D. Developing an equivalent in-house solution would require at least 3-4 years and substantial investment in material selection, reaction mechanism elucidation, equipment design, and validation testing.
