STN International’s Content– Comprehensive and Pertinent

STN International provides users with access to some 100 databases comprising about 1.5 billion documents.

Added value means you get more: At FIZ Karlsruhe specialists check the data for accuracy through data analysis and data interpretation. The work focuses on STN International's patent databases, including the ongoing development and refinement of standardization procedures for patent applicant names and the various systems for numbering patents.

A Focus on Chemistry Databases

For more than thirty years STN has been offering scientists in research and industry access to key chemistry databases from many renowned database producers. The search features allow for chemical structure searches: A structure editor enables targeted searches for chemical structures and reactions.

Professional, Precise Search Options

STN’s search system is specifically engineered for scientific and patent content, allowing for very precise searches for facts, text matches, chemical structures, and biosequences. It is essential for patent searches that the results be comprehensive and do not omit any potential hits (recall).


On the other hand, only those results that best match the search query are desired (precision), and as many unwanted results as possible are to be eliminated. STN’s features are perfectly suited for using both generic queries for high recall and very precise queries in order to obtain the best results possible.

Systematic Patent Analysis Based on Expert Searches

Analysis and visualization of search results are important steps in order to detect new research trends and patent application behavior early, to identify important players, and to discover new options for existing technologies.

Uncompromisingly High Quality

All STN information undergoes a multi-level quality assurance and control process before it is included in the online service. Although the database publishers only accept publications into their databases from reliable sources, another strict quality assurance process is required. A uniform database design is created and the information is standardized throughout all databases.

We are Your Reliable Partner for Business-critical Patent Searches

We place high priority on data security, user privacy, and the confidentiality of your search queries. While public search engines analyze user queries in order to display customized advertising, we do not store or analyze queries or search strategies. And we never determine or disclose to third parties why research and patent information was retrieved from STN databases.


At FIZ, we collect information for you, not about you.
