CAS IP Finder

CAS IP Finder, powered by STN™, is a comprehensive intellectual property search and analysis platform designed for IP professionals who need complete, precise, and trustworthy results. Built for patent attorneys, IP analysts, information professionals, and business strategists, it combines broad global database coverage with advanced technical search capabilities in a single, intuitive interface—eliminating the fragmented workflows and coverage gaps that put R&D investments at risk.

Missing a single piece of prior art can invalidate years of research and cost millions. CAS IP Finder addresses this challenge by unifying access to scientific literature, global patent databases, and chemical substance data in one platform, ensuring that no critical reference is overlooked regardless of language, geography, or document type.

Core Coverage and Data Access

• Access to 100+ global scientific, patent, and technical databases in one unified platform, replacing fragmented multi-source searches.
• Search across patent documents from major authorities including USPTO, EPO, WIPO, and more than 100 additional international sources for true global coverage.
• Access to 230 million chemical substances searchable by structure, not just keywords, uncovering prior art that standard text searches cannot find.
• Coverage of both patent and non-patent literature, ensuring no relevant scientific publication is missed.

Advanced Search Capabilities

• Chemical structure searching — find every relevant chemical compound whether it is described through written language or drawn structural representations.
• Biological sequence searching — search protein, DNA, and RNA sequences to identify prior art for biologics, gene therapies, and related innovations.
• AI-enhanced exploratory search — a new search mode that delivers patent and non-patent literature results without requiring database selection or complex search syntax, automatically detecting keywords and registry numbers (RNs).
• Multiple search modalities — a user-friendly interface designed to make patent searching accessible without requiring advanced command-line knowledge.

Workflow Efficiency Features

• CAS PatentPak® integration — highlights key scientific data within full-text patent claims, enabling rapid relevance assessment without reading entire documents, saving significant time during review.
• Streamlined interface combining the trusted precision of STN with modern usability features to simplify complex search workflows.
• Eliminates the need to choose between comprehensive coverage and technical depth, providing both in a single platform.
