Why Multi-file Searching?

• STN contains data from over 100 databases

• Different files contain data from various sources, document types, and collections

• Even databases that cover similar sources (i.e., patents from major issuing authorities) might have different inclusion criteria, indexing policies, or periods of coverage

• Database producers also include different types of value-added content to records for the same publication

An INPADOCDB record includes all patent publications issued by the same authority

All patent publications of one patent family (invention) form one record in INPAFAMDB

Full-text Patent Databases

• Primary source patent databases‒ Includes full text of the original document, including claims

• Many full-text patent databases available on STN‒ USPATFULL, PCTFULL, EPFULL, DEFULL, CNFULL, etc.

• Many full-text patent databases also have numeric property searching capabilities, making it easier to extract meaningful results from full-text search queries

• Why multi-file searching?

• Maximizing benefits in different files– File-specific fields and formats– Thesauri– Database Summary Sheets

• Case Study– Specialized Indexing– Legal Status events

Agenda

Take advantage of database-specific fields and features to get more out of your search• Many files have unique fields for search and/or display that

showcase aspects of the data in the file

• Thesauri, including controlled terminology and classification schemata, help to retrieve documents indexed by experts

• Specialized data types (legal status events, Markush structures, proprietary classification systems, e.g.) may be unique to specific databases

12

File-specific fields and features: Derwent World Patents Index• Available in several versions

‒ WPIDS – subscriber file‒ WPINDEX – standard file‒ WPIX – subscriber file with extension abstract

• Access to WPIDS and WPIX requires a relevant subscription from Clarivate Analytics

• WPINDEX is available to those without subscriptions

13

File-specific fields and features: Derwent World Patents Index• Unique indexing at both invention and publication level

‒ Chemical and electrical indexing, structure drawings, and other data from individual family members is de-duplicated and collated

‒ Additional specific indexing at member level‒ Invention and Member Patent levels can be searched individually or in

combination

• Numeric property values of 55 physical and chemical properties, searchable in all English-language text fields

14

File-specific fields and features: Derwent World Patents Index• Basic Index Extended (/BIEX) field includes single terms from fields in

addition to those included in the Basic Index (/BI)‒ /BI includes: AB, ABDT, ABEQ, ABEX, ACTN, ACTV, ADV, ALE, DETD, DRWD, NOV,

TECH, TI, TT, UADV, and USE‒ /BIEX additionally includes terms from author abstracts, claims, and titles

• Additional specialized indexing available to subscribers‒ Fragmentation code searching‒ Polymer Indexing‒ Chemical Manual Codes‒ Abstract extensions‒ Documentation abstracts

15

File-specific fields and features: Derwent World Patents Index• Specialized fields in the Chemistry Resource Segment allow for

specific retrieval of substance information‒ Chemical Name, Classification Code, Controlled Term thesaurus, Derwent Drug Registry Name,

polymer indexing, fragmentation codes*

• Thesauri available to increase search precision‒ European Patent Classification (/EPC), F-Term (/FTERM), FI-Term(/FCL), ICO

(in-computer-only) Classification (/ICO), International Patent Classification (/IPC), Cooperative Patent Classification (/CPC), Manual Code (/MC), Polymer Indexing Enhanced (/PLE), Title Terms (/TT), and US National Patent Classification (/NCL), Compound Number (/DCN), Registry Number (/DRN), Patent Assignee Code (/PACO), and Plasdoc Key Serials (/KS)

16

17

• Numeric values play a key role in patents which use chemical and physical properties to set the scope of patent protection‒ Exact values are typically expressed in broad ranges

• Searching numeric data in patents is challenging‒ Standard text searching tools are too limited ‒ Great variety of properties and units and a great variation of

representation

• Databases with numeric property searching enabled are listed on the STN International website as well as grouped in a cluster

Numeric Property Searching can be used in DWPI to refine answer sets and retrieve highly relevant records

HELP NPS offers database-specific NPS help

18

Extracting, normalizing and indexing numeric data

19

Extracting, normalizing and indexing numeric data (cont.)

• Numbers and their units within the English-language text are identified

− About 1,800 property unit variants are identified

− Numbers are considered from exact values, closed ranges and open ranges

− Numerals are detected as well

20

Extracting, normalizing and indexing numeric data (cont.)

• Identified original data are normalized to base units and indexed for searching− 55 numeric property search fields with their respective base units are

available

− Additional units (CGS-units, imperial and US customary units) are converted to base units

File-specific fields and features: INPADOCDB/INPAFAMDB

• Patent classification codes – CPC, IPC, US National, and Japanese F- and FI-terms

• Standardized Patent Assignee (/PAS) search field

• Super Search fields for Application and Patent Number Groups as well as Inventor Group and Patent Country Group

• Extensive legal status information‒ >210M legal status events in >44M records dating back to 1968

21

Calculated expiration date search and display• Calculated expiration date is included in all standard display

formats, BIB, ALL, MAX, etc.

• The custom display field XPD is also available

• Calculated expiration date (/XPD) and year (/XPY) search options are available:

22

=> S 20131020/XPD

=> S 20140601-20150601/XPD

=> S XPD>20121001

=> S 2013-2016/XPY

Specific expiration dates/years or ranges may be searched.

Expiration dates and years can also be analyzed

Legal Status searching in INPADOCDB/INPAFAMDB

• Legal status information is searchable with about 4,100 legal status codes (LSC, LSTX)

• Many search and display options, e.g.

applicant reassignment LSPA

opponent LSOP

legal effect date LSDF

legal status date LSD

25

Searching for Legal Status Events

• Search either code in the LSC field or the text describing the code in the LSTX field

• Use sentence (S) in the LSTX field to limit to the same legal status events

=> S (EXPIR?(S)FAIL?)/LSTX

• Use the L-operator to link LSTX or LSC to the INPADOC Legal Status Date (LSD)

=> S WOENP/LSC(L)20031002/LSD

26

Legal Status Code (/LSC)

• Complex set of legal status codes‒ Difficult to use for legal status searching

• Codes vary from country to country• Code definitions may change over time• New codes are introduced• Comprehensive searches require sophisticated strategies and

deep understanding of various granting procedures

27

Legal Status Categories (/LSC2)

• Legal status code categories provide an easy access to more than 2,600 specific legal status code information‒ Reliable and easy to use legal status search tool‒ Well applicable to specific legal status monitoring ‒ New codes and code definition revisions will be reviewed and included by

the FIZ Karlsruhe editorial experts

Search Question:Find patents about electric bikes stating battery charging times of one hour. Search for patent information as well as claim language and legal status events for these patents.

Case Study Search Strategy

• Search in the Derwent World Patents Index for appropriate manual codes, IPC and CPC classification codes, and keyword language for electric bikes‒ Add Numeric Property Searching to retrieve documents with specific

reference to rapid charging times (1h)

• Search in INPADOCDB/INPAFAMDB for legal status events

• Transfer patent numbers to full-text patent databases to display claim language

• Use the Patent Family Manager to customize results display
