Launch of Version One of new STN® begins new era in IP searching

03. July 2013

Professional user interface, industry leading performance, and workflow synergy are hallmarks of the new STN

Karlsruhe/ Germany and Columbus/ Ohio (July 2, 2013) - The STN partners, FIZ Karlsruhe and Chemical Abstracts Service (CAS), are pleased to announce the launch of Version One of the new STN platform! Users from hundreds of organizations around the world explored Version One during the half year of beta testing, providing valuable feedback. Their feedback confirms that the new STN platform design, project-oriented workflow, search power, precision, and speed meet professional searchers’ exacting demands and exceed their expectations. The broad release of Version One of the new platform extends the benefits of this new technology to all organizations using STN under fixed fee programs. Version One is the first step toward a modern and powerful new STN system.

Version One of the new STN platform delivers core STN content including the complete CAS REGISTRYSM and CAplusSM content along with Thomson Reuters’ Derwent World Patents Index® (DWPISM), including the Derwent Chemistry Resource (DCR). Proprietary search technology offers new features that allow for STN’s unique content offering to be explored in new ways. With its advanced design, STN’s intuitive user interface is oriented toward the work processes of patent specialists. Users can manage their search strategies and results in dedicated “projects”, which enable search professionals to organize and efficiently work on numerous projects concurrently. Specific emphasis has been placed on workflow. The user interface has been designed to show search query, history, and results at a glance while highlighting the most relevant answer sets. The greatly increased search capacity allows for completely new approaches to searching and results evaluation. For example, within seconds the results of a chemical structure search of more than 70 million substances, can be executed and the results filtered according to their pharmacological and toxic effect when used in drugs or as pesticides.

“The much faster search execution, integrated real-time analysis, more efficient results interaction, and increased search capacity leads to a superior user experience. We believe that the new platform is a leap into the future of IP searching,” said Sabine Brünger-Weilandt, President and CEO of FIZ Karlsruhe.

Robert Massie, President of CAS noted that users will be supported on both current and new STN platforms, with access on the new system provided initially to fixed fee customers. Access will be extended to transactional customers in 2014. He also confirmed that the STN partners will continue to fully support and enhance the classic STN platform during the transition period.
