Largest content expansion to date extends the enhanced new STN search experience to a broader range of users

Columbus, Ohio and Karlsruhe, Germany (February 9, 2015) – Chemical Abstracts Service (CAS) and FIZ Karlsruhe are pleased to announce the latest release of the new STN platform, a web-based search solution offering essential, value-added content in an intuitive, powerful interface designed for professional IP searching. New databases deliver highly anticipated content, including premier biomedical databases BIOSIS®, MEDLINE® and EmbaseTM, complementary life science databases CABA and FSTA, and full-text databases that expand global patent portfolio coverage beyond what is available on the classic STN platform.

“New STN is a modern, efficient research solution, and the addition of new biomedical and patent databases allows more IP professionals to take advantage of this enhanced search experience” said Christine McCue, vice president of marketing at CAS.

The latest release also includes new features and interface refinements that enhance efficiency and usability. Additional thesauri, including the Embase Emtree Thesaurus and MeSH Medical Subject Headings in MEDLINE, enable discovery of search terms and synonyms for even more comprehensive retrieval. Highly requested hit chemical structure displays and CAS Registry Number® highlighting speeds answer review by indicating the relevant chemical entities in CAplusSM search results. In addition, INPADOC enhancements, including new family displays, increase users’ ability to leverage global patent content to answer business-critical questions.

New STN delivers the high-quality content, search power and precision needed to understand and protect intellectual property in today’s global economy. As searchers increasingly adopt the new platform, they have expressed appreciation for the enhanced search power, intuitive chemical structure search capabilities, and unique features, such as Extended Patent Family Tables, that enable them to search in ways that had not previously been possible. Users also praise the project-oriented workflow and intuitive interface that enhance their efficiency by integrating real-time analysis with query development and answer set review.

“This release marks an important milestone in bringing STN’s value-added content portfolio to the new platform,” said Dr. Rainer Stuike-Prill, vice president marketing and sales at FIZ Karlsruhe. “Feedback from users is instrumental to our progress, and we are excited to offer new content and features that deliver highly requested enhancements.
