Addition of SCAN format to selected STN databases

Annual Reload of IFI Databases

The IFI Patent Database (IFIPAT), IFI Comprehensive Database(IFICDB), and IFI Uniterm Database (IFIUDB) were reloaded in November.

Search and display enhancements in this reload include addition of the DISPLAY SCAN format to help evaluate usefulness of answer sets.

Content enhancements in the reload included:

IFI intellectual indexing for more than 70,000 additional published applications.
Updating of patents and applications throughout the IFI database to reflect reclassifications of USPTO class codes and IPC codes that have been revised through December 2008.
Assignee Name changes that occurred during the year have been applied to all affected records in the back file.
Addition of a Multiple Assignee indicator to identify patents throughout the database (1950-2009) having more than one assignee.
Enhanced indexing with many new terms for various green technology areas such as biofuels and biodegradable polymers. (Use these terms to find patents and concepts not easily located using class codes or text searching, e.g., Biofuels 11033/UN).
Back file postings for many FDA Orange Book listed patents.

DGENE, PCTGEN, and USGENE: new local percent identity feature for sorting BLAST answer sets

A new local percent identity field (IDENT) has been introduced in the Derwent
Geneseq (DGENE), USPTO Genetic Sequence Database (USGENE), and World Patent Application Biosequences (PCTGEN) databases. The IDENT field can be used to SORT BLAST answer sets from these databases, either individually or in any combination. Sorting with this BLAST parameter can be helpful in identifying short, highly similar sequences with low overall homology scores. The IDENT field
can also be displayed within records from these databases.

IDENT can be used in combination with the conventional homology sorting parameter SCORE and with the FSORT command. When FSORT is applied to an answer set previously sorted by IDENT and SCORE, the sort order is retained for each family, thus adding flexibility to the display of BLAST answer sets.

Additional details on this feature are available at:

PCTGEN enhanced with patent family and legal status display data from INPADOCDB

The World Patent Application Biosequences database (PCTGEN) has been
enhanced with addition of predefined patent family display formats FAM and CFAM and the legal status display formats LS and LS2 from the International Patent Documentation Database (INPADOCDB).

The INPADOC information helps to identify those sequence records from a PCTGEN sequence search which refer to the same INPADOC family.

Addition of DISPLAY SCAN format to selected STN databases

To facilitate easier review of search results in a multifile search environment, the DISPLAY SCAN format has been added to the following databases:

EMBAL, EMBASE, LEMBASE, ENCOMPLIT, ENCOMPLIT2, ENCOMPPAT, ENCOMPPAT2, IFICDB, IFIPAT, IFIUDB, MEDLINE, and LMEDLINE.

The DISPLAY SCAN format can be used to view answers from an L-number answer set at no charge. Answers are displayed in a predefined format, in random order, and without answer numbers. The predefined formats vary according to the database.
