New SciFinder® Enhancements

The web version has been enhanced with powerful new features to help SciFinder users:

View experimental procedures directly in SciFinder
Within SciFinder, users will be able to view experimental procedures (covering the period of 2005-2009) from six American Chemical Society journals as well as patents from the USPTO, EPO, and WIPO. Users will also be able to examine, sort, and analyze experimental procedures for applicability to their synthetic research needs and more efficiently determine lab preparations and plan synthetic pathways.

Get structures more efficiently using SMILES and InChI strings
Chemists can now save time drawing structures by converting InChI (International Chemical Identifier) or SMILES (Simplified Molecular Input Line Entry Specification) text strings within the drawing editor into graphic representations of specific substances.

Sort search results by relevance
Reaction results can now be viewed and sorted from most to least relevant, bringing the most important information to the researchers attention immediately.

For more information about all the new features, see How To Use the New Features (pdf)


SciFinder Autosave Feature

The AutoSave feature is now available in the web version of SciFinder for all academic customers.

The AutoSave feature will automatically save the current answer set if the SciFinder session is inactive for more than 20 minutes.


  • After 20 minutes of inactivity, SciFinder prompts you with a message to continue the session or to log off. If you do not respond (and the system proceeds with an auto log off), the AutoSave feature automatically saves the current answer set.


New PNK Field Allows More Precise Crossover among STN Patent Databases

To provide more precise patent publication number crossovers, STN has introduced the PNK (Patent Number/Kind Code) field for use when transferring patent publication numbers between databases. PNK field crossovers can be used to transfer publication numbers of published applications and granted patents. A new PNK.B (Patent Number/Kind Code of the Basic Patent) field also has been implemented in CASM/CAplusSM and is expected to be implemented soon in the Derwent World Patents Index® (DWPISM) and in the INPAFAMDB/INPADOCDB family of databases.

PNK has also been added to these databases:


PNK is available for SEARCH, DISPLAY, SELECT, and ANALYZE. (In the DWPI and INPADOCDB/INPAFAMDB databases, however, PNK displays will be the same as PN displays.)

The PNK field is necessary because some patent-granting authorities use the same numbering schemes for both patent applications and granted patents, or for both patents and utility models. This caused searching difficulties for customers crossing over patent publication numbers, particularly when Japanese, Chinese, and Taiwanese patents were involved.

When you need to transfer patent publication numbers from one database to another, the PNK field will enable you to transfer them precisely. Just use TRANSFER PNK rather than TRANSFER PN to achieve better quality results.


New version STN Viewer

The new version of STN Viewer preserves custom highlighting of terms when patent documents are saved in .rtf format

A new release of STN Viewer allows you to preserve customized-highlighting of terms of interest when saving original STN Viewer patent documents to .rtf format. Now your colleagues and managers can quickly review patent documents in .rtf format, either print or electronically, by relying on the navigation points provided by your highlighting.


Databases verwijderd van STN
De volgende databases zullen per 31 december 2010 niet meer beschikbaar zijn via STN:
  • HSDB
  • MDF
  • NLDB



CABA on STN is reloaded

Your saved answer sets in this file will be kept and can be activated and searched as usual.

If you want to display records from an saved answer set directly, please run this simple search first
(L#: L-number of activated answer set)
=> S L# or L#
otherwise an error message will occur.



New format for Korean patent application numbers in CASM/CAplusSM increases consistency, saves time

Numerous Korean patent application numbers (/AP) and priority application numbers (/PRN) in the CA/CAplus family of databases formerly consisted of six digits. A new seven-digit format has been adopted to ensure conformity among the CA/CAplus family and other important STN® databases.

The new format contains a zero (0) inserted immediately following the 7, which is always the first of the seven characters in the serial number (see example below). This change applies to 90,000 Korean application numbers and to approximately 3,000 priority application numbers in patents from 1999 to the present.

The new format will make crossover searching easier and will save you time by ensuring that patent number crossovers among STN patent databases are comprehensive.

Format for Korean Patent Application Number and Priority Application Number

Previous format
KR YYYY-7nnnnn
(e.g., KR 2000-710051)

New format
KR YYYY-70nnnnn
(e.g., KR 2000-7010051)

Kind code changes for Chinese patents; new formats for Taiwanese application numbers in CA/CAplus

Kind code changes for Chinese patents
Chinese utility models with a publication date of October 6, 2010 or later will now use kind code U in the CA/CAplus family of databases. The kind codes for Chinese utility patents with publication dates of April 7, 2010 thru October 5, 2010 will be updated from Y to U. These changes impact both basic patents and equivalents, will make crossover searching easier, and will save you time by ensuring kind-code consistency among CA/CAplus and other STN databases.

The formats of Taiwanese patent application numbers (/AP) and priority application numbers (/PRN) have changed in the CA/CAplus databases to be consistent with other STN databases. These changes ensure that you will receive a complete set of records when you cross over patent application numbers among several STN databases.

The new formats will be applied to new Taiwanese applications and CA/CAplus backfile records, and differ from previous formats by the deletion of the first two characters (that corresponded to the Taiwanese year) immediately following the dash:

Previous format: TW 2005-94114837
New format: TW 2005 -114837



Search an additional 46,850 records with MEDLINE backfile extension to 1946

Now you can search an additional 46,850 bibliographic records recently added to the MEDLINE backfile, extending its coverage to 1946.

NOTE: None of these backfile records supplied by the National Library of Medicine (entry date /ED of 20101000) included abstracts. You may encounter a small number of existing publication-year 1946 MEDLINE records that do contain abstracts, but those records were not part of this enhancement.



Enhancements to the US national patent classification in the INPADOC files
The issued US national patent classification (NCL) is available for 6 million US applications in the INPADOC databases back to 1968. The NCL codes have now been standardized according to STN-standard rules and a NCL-thesaurus has been introduced to support patent classification searching. In addition, the Locarno classification for US design patents (US S1) is provided in separate search and display fields. The US classification enhancements greatly support the retrieval of US patent publications in the INPADOC files.

The NLC-codes have a specific 9-digit format: the first three digits represent the class and the following six digits the sublass. Searches can be run at class or subclass level, we also distinguish between main (NCLM) and secondary (NCLS) US classification codes. The NCL codes are included in the predefined display formats IND, STD, ALL, MAX and BRIEF.

Search examples for US classification codes

=> S 455/411.000/NCL
=> S 455411000/NCL
=> S 455/NCL
=> S 455/411.000/NCLM
=> S 455411000/NCLS

The US national patent classification thesaurus is attached to the NCL field and allows to view the definitions of the NCL codes and their respective hierarchies. The relationships can also be employed for hierarchical and range searching. The definitions of the codes are searchable which allows to find appropriate codes for a certain topic. See HELP THESAURUS and HELP RCODE for further details.

The INPADOC files cover the Locarno classification for US-design patents from April 2005. The classification codes can now be searched with the new LCL-field. The Locarno classification is provided with the predefined display formats IND, STD, ALL, MAX and BRIEF.

Search examples for Locarno classification codes

=> S 12-16/LCL
=> S 1216/LCL

In the course of standardizing the US national classification codes, we moved all national classification codes from other patent authorities to the new field OCL. The INPADOC files cover national patent classifications for 12 patent authorities for selected time ranges. The major collections refer to German utility models (1950-1974) and GB A-publications (1977-2008). The classification data in the OCL-field are not standardized.

Colombia Legal Status
The EPO announced that at the beginning of January 2011 legal status data from Colombia will be available:



The CAS REGISTRY sample search option is enhanced

The CAS REGISTRY has witnessed extraordinary growth over the past few years with approximately 12,000 new substances now added daily. The REGISTRY database currently contains more than 54.9 million organic and inorganic substances--all potential candidates for matching your structure query.

To keep pace with this ever expanding database content, the iteration limits for sample searches have been increased from 2,000 to 1 million records. This will ensure that sample searches continue to be accurate representations of full database search results.

The increase in iteration limits will enable the majority of your sample searches to run to completion; however, you will continue to receive no more than 50 randomly chosen records for each sample-search answer set.
