STN at a glance

STN is an online database service that provides global access to published research, journal literature, patents, structures, sequences, properties, and other data. As a neutral platform STN provides access to a broad range of databases from the most renowned database producers worldwide. STN is operated jointly by CAS and FIZ Karlsruhe worldwide and is represented in Japan by JAICI .

STN integrates the world’s largest and most important value-add and first level patent databases on one platform. Patent databases on STN are key information resources for determining patentability, state of the art, infringement, and the legal status of the patents, in other words for making business-critical decisions. And: Only on STN you can search patent information from Clarivate Analytics, Chemical Abstracts Service (CAS), and the European Patent Office’s worldwide Patent Information Resource in one place! STN also provides full-text patent databases from the European Patent Office (EPFULL), United States Patent and Trademark Office (USPATFULL), World Intellectual Property Organization (PCTFULL), and more. The unsurpassed collection of essential sci-tech and medical databases on STN covers a wide range of topics. Topics covered by STN databases include
• Bioscience
• Biotechnology
• Business
• Chemistry
• Energy and Environment
• Engineering
• Health and Safety
• Materials Science
• Medicine
• Nanotechnology
• Pharmacology
• Toxicology
• and more
In addition, STN provides the largest repository of publicly available bio-sequence information from patents and the journal literature. Biosequence information is stored in highly specialized databases on STN. These databases contain polypeptide or nucleotide sequences as well as information about the source organism, gene descriptions, protein activities, regulation, and function notes.

For details about the STN interface see STNext™.

The full-text of documents for which references have been retrieved in STN databases can be accessed via the STN Full-Text Solution. By clicking the "Full-Text" button in an STN database record, you will get seamless access to the full text of the original document via the STN Full-Text Solution. The STN Full-Text Solution consists of two services:
ChemPort Connection: A free service that provides access to full-text documents which are electronically available with publishers, subscription agencies, patent offices, or patent document services. An access to your corporate library holdings can also be integrated.
FIZ AutoDoc: FIZ Karlsruhe´s broker service for document delivery.

To access STN you need to obtain authorization from your STN service center. See Prices and Terms.

Since 1984, STN International has been jointly operated and furthered by a close collaboration between FIZ Karlsruhe and CAS (Chemical Abstracts Service), based in Columbus, Ohio.
