STN on the Web Enhanced with New Patent Family Assistant and Updated Structure Plug-In

STN on the Web was updated to include a new Patent Family Assistant and an updated Structure Plug-in.

The new Patent Family Assistant is located in the Assistants folder (previously Search Assistants folder) and allows you to:

  • Extract the first member from each patent family: Use this feature to include only a single member from each patent family in your answer set.
  • Remove twin multiple basics from patent families*: Use this feature to manage the multiple basic patent content of a CA/CAplus answer set with the option to retain the:
    • WO basic patent,
    • national basic patent with oldest priority,
    • patent with the oldest application date or
    • patent with the oldest publication date.

  • Customize displays of patent family results: Save time and money by selecting different display formats for the first family member of a patent family vs. equivalents.

Take advantage of improved structure drawing and searching capabilities available with the updated Structure Plug-in (version 8.5).

*This feature of the new Patent Family Assistant is also new to STN.


MARPAT Enhancements Save Time and Increase Usability

Save time in post-search answer review with enhanced query-focused displays in MARPAT. The QHIT and FQHIT display formats have been enhanced to provide more recognizable results by assembling the query-focused fragments. The assembled answers increase understanding for users, while making it easier to share MARPAT information with other decision-makers.

Enhanced FQHIT display for the same

The new assembled displays will be the default for these formats. The SET MPTASSEMBLY command can be used to select ON, OFF or BOTH displays in these formats. SET MPTASSEMBLY BOTH will display the new assembled structure and the old format.

Two new MARPAT display formats, FQHITEXG and QHITEXG, are also being introduced. In addition to the FQHIT and QHIT information, these formats will provide definitions for all unmatched G-groups shown in the answer.

FQHITEXG defines all unmatched G-groups

 

Additionally, the PNK and PNK.B search fields (Publication Number + Kind code) have been added to MARPAT.

In addition, enhancements to the MARPAT search algorithm have been implemented to increase search precision in CSS (Closed Substructure Search) searches that employ connectivity settings.


INPADOC: Delay of German Patent Coverage

The European Patent Office informed us about significant delays of the coverage of German bibliographic and legal status data in INPADOC from the week 25/2011 (June 12-8):

'Due to a complex and unforeseen combination of technical  
problems we have to warn you that there may be delays or 
even an interruption in delivery of DE data from week 25/2011. 
Our technical experts are working on these problems as their 
top priority. All our efforts are dedicated to ensuring the 
continued timely delivery of raw data products including DE data. 
Currently we foresee an interruption of several weeks.'

On STN, bibliographic data of German patent publications are also available in the patent full-text database PATDPAFULL and in the value-added databases CAplus and Derwent World Patents Index. These databases are not affected and will provide German patent data as usual.

We will keep you informed about further developments.


INPADOC Databases Enhanced with First Page Images

The INPADOC databases INPADOCDB and INPAFAMDB have been enhanced with first page images for patent publications of 8 major patent authorities. This new graphical information greatly supports relevance checking of technology search results.

First page images can be displayed with the standard display format GI and several predefined display formats in both INPADOC files. For a list of image display formats and coverage details see INPADOC News 2011/06: http://www.stn-international.com/inpadoc_news_201106.html


WPINDEX/WPIDS/WPIX: DWPI Country Coverage Update

Derwent World Patents Index (DWPI) now also covers patents from Poland and Hong Kong. This brings the number of authorities covered in DWPI to 47, further strengthening the global coverage of editorially enhanced content in the file.

Coverage includes DWPI titles and/or abstracts with CPI/EPI manual coding, and for the Polish content deep indexing (polymer indexing, fragmentation codes and Markush Indexing) where relevant. The first records to be released will be those published in January 2011.

Patents filed through the Gulf Cooperation Council
The patents filed through the Gulf Cooperation Council will soon start to appear in product, as early as DWPI updates 201130 or 201131. Records published in the official gazette volume 13 (covering the publication period October 2009 to April 2010) are now being processed by the DWPI editorial team.

The Gulf Cooperation Council regional office covers the following Arab states - Bahrain, Saudi Arabia, Oman, Kuwait, Qatar and the United Arab Emirates. Records identified as basics will include DWPI titles and abstracts, CPI/EPI manual coding and deep indexing (polymer indexing, fragmentation codes and Markush Indexing) where relevant. Records identified as equivalent already joined their existing DWPI family as normal. The number formats for the new content are shown below.

Document Description: Gulf Cooperation Council Granted
Kind: B
Raw Patent number: 0000774
DWPI patent number: GC774B
Raw application number: GCC/P/2002/2203
DWPI application number: 2002GC002203 A2

Taiwanese Utility Models
In DWPI update 201133 we resumed the loading of the Taiwanese Utility Model records that were published in 1998 and 1999. These records will have the kind code U1. Previously the TW Utility Model coverage in DWPI went back to January 2000.

The kind codes for the Utility Models published from 2000 to August 2004, will change from the kind U to kind U1 to ensure consistency for these old law records. All of the records will be reissued into DWPI with this amended kind code.

The 'new law' Utility Model records published from August 2004 onwards will continue to have the kind code U as is currently the case. Updates to the ongoing data are currently on hold and will resume once the 2000-2004 data has been reissued.

Chinese Granted Patents
From DWPI update 201131 the coverage of Chinese Granted patents in DWPI will be enhanced with the inclusion of an English language translation of the 1st claim at the DWPI member level record. Translations of the 1st claim will be available for all of the Chinese Granted patents published from January 2011. This enhancement to DWPI will enable users to compare differences between the first claim in the Chinese application and the subsequently published Chinese granted patent in the same family.


Examples of customer questions and answers

Q. How can I refine my substance search using ring information?

A. You can use ring information to search REGISTRY for substances containing rings based on the number of rings, ring formula, etc. Ring Identifiers (/RID) are special dictionary terms, represented by a 3-part numeric sequence such as "2983.4.10". The first part "2983" codes the ring system arrangement; the second part "4" codes for ring atoms; and the third part 10 codes for the exact bonding pattern in the ring system.

If you know your RID, you can search REGISTRY using the corresponding numeric sequence followed by the "/RID" field code.

To locate the RID for a particular ring, you should first display a structure of interest and then enter "D RSD" at an arrow prompt for a structure of interest. You can use the first two groups of digits in the numeric sequence to identify substances with the same or similar ring system/atom arrangement.

Searching the full 3-part numeric sequence may be too limited, although it will find other substances in  REGISTRY with identical ring systems and the specific bonding pattern of the original substance.


Q: How can I display only the CAS Registry Number(R) and structure from CAS REGISTRYSM structure search within the coordinating CAplusSM records that have been indexed with a biological role indicator? 

A: Cross-over the L# from the REGISTRY structure search with the appropriate Role Code and display the CAplus records with the hitstr display format. Below is an example.

 

 

 


Q: How can I limit my CAplus patent answer set to only answers where at least one patent equivalent was published before a given date.

A: Since CAplus records are built into inventions with equivalent applications and granted patents grouped into one record, include in the query a numeric value (or range) using the /PD search field. Below is an example.
