Version One of new STN® - the foundation for the future of patent searching

Version One of the redesigned STN introduces project-oriented workflow, improved usability, and “no limits” search architecture for expert as well as novice professional searchers

The STN partners, Chemical Abstracts Service (CAS) and FIZ Karlsruhe, are pleased to announce that Version One of the new STN platform is now available in beta for fixed fee customers. This is the first major milestone in a multi-year initiative to create the next generation of STN, the choice of patent experts.

The focus of this first version has been on developing the core search and retrieval system for new STN. This release combines the complete CAS REGISTRYSM and Chemical Abstracts content along with Thomson Reuters’ Derwent World Patents Index® and powerful new search features to support preliminary searches in these key areas:

• Chemistry and general technology research
• Intellectual property, such as basic novelty and prior art
• Due diligence
• First pass freedom to operate.
A new approach for STN is to allow organization of work in projects for easy management of search queries and results. New technologies are designed to process broad and complex searches with industry-leading performance. This is vital for patent searchers to keep pace with the continued increase of disclosed research and patent information from around the world.
The new workflow integrates the power of command line with an intuitive user interaction that enables professionals to leverage their expertise and realize instantaneous results. For the first time, text and structures can be combined in a single query to simplify searching for chemical information.

The STN Partners will incorporate additional content and functionality in the new architecture with ongoing versions. Full text patent content will be added throughout 2013.

“In October 2011, we announced that a new STN platform was under development and that a completely new STN will be phased into the market beginning in 2012. Consistent with the long tradition of STN keeping promises to customers, we are pleased to achieve this milestone of beta availability of the first version to our customers around the world who use STN on a fixed fee basis,” said Bob Massie, President of CAS.

"We are confident that patent search professionals will be very pleased with the industry-leading power and precision that we have built into the new STN,” said Sabine Brünger-Weilandt, President and CEO of FIZ Karlsruhe. “Our global advisory council has been instrumental in providing guidance and identifying how STN can meet needs not met by other search services.”

The STN Advisory Council members have been assisting in this large development effort, and confirm that CAS and FIZ Karlsruhe are building a state-of-the-art product for professionals:

“It has been amazing to see the new STN develop over the last two years - from a concept through the alpha version to the present beta version. This new STN will have important new features: No system limits! Simultaneous searching of Registry and Chemical Abstracts! Quick previews of references retrieved! I am looking forward to using new STN to increase my productivity and enhance management of my search projects.”-- Gayenel Rice, 3M

The current STN system, including STN Express® and the other STN products will continue to be available and fully supported throughout the development of the new platform.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
