Abstract

This study proposes a robust, data-driven framework for optimizing global patent deployment strategies, focusing on hinge technologies developed by the Watson Group. Drawing from 257 patent applications across 30 jurisdictions, the research integrates macroeconomic and intellectual property (IP) indicators with legal risk considerations. Unlike traditional models, this study adopts the Analytic Hierarchy Process (AHP) to derive weights for 11 strategic indicators, including GDP, patent activity, and hinge-specific innovation trends. Furthermore, a Legal Risk Scoring (LRS) model is introduced to evaluate jurisdictional enforceability and litigation exposure. Countries are ranked based on composite scores and visualized through a two-dimensional deployment matrix. Sensitivity analysis confirms model stability under ±10% weight variation. Results highlight strategic opportunities in Austria, Italy, and Brazil, while reinforcing continued investment in the U.S., Germany, and Korea. The framework offers actionable insights for IP managers and can be generalized to other technology sectors. JEL classification numbers: 034.
