Quantify outcomes and outmaneuver opposing counsel with the industry's most accurate Legal Analytics®.

The global gateway to intellectual property through AI-powered search and neural translation.

PATENTSCOPE is the World Intellectual Property Organization's (WIPO) flagship database, providing access to over 112 million patent documents, including 4.8 million published International Patent Applications (PCT). As of 2026, its technical architecture has evolved into a sophisticated AI-first environment, utilizing advanced Neural Machine Translation (WIPO Translate) to break language barriers across 14+ language pairs. The platform integrates Cross-Lingual Information Retrieval (CLIR) which uses semantic expansion to identify relevant technology even when search queries are limited by keyword variance. For deep-tech sectors, its Chemical Structure Search capabilities allow users to query by drawing molecules or uploading SMILES/InChI strings to identify chemical entities within patent corpora. Positioned as a mission-critical utility for R&D departments and IP legal counsel, PATENTSCOPE bridges the gap between raw data and actionable intelligence by providing high-fidelity OCR, sequence search functionality, and real-time legal status updates. It remains the gold standard for global prior art searches due to its official mandate and integration with national patent offices worldwide.
