Data Sources and Patent Family Overview Patent family Data Sources | Page 5

Patent family & Data Sources ➢ The field of genetic engineering is known to have INPADOC patent families reaching thousands ➢ The updating of INPADOC database mainly dependent on national patent office, which may not be able to provide regular updates. Another difficulty of relying on national patent office for the raw data is the quality of data. This leads to data error ➢ This patent family data product is available to commercial patent information providers; it is the basis for many patent family databases Derwent World Patents Index: ➢ Uses human indexers to add abstract, indexing codes and re-written titles ➢ Patents records are organized into intellectually created families, so that each family represents single subject invention ➢ Creation relies on priority data ➢ It is a simple patent family but systematically identifying non-convention equivalents which can make it as artificial patent family ➢ DWPI database can never be current as all the new basic documents with unique priority data needs to be indexed before feeding them to database CAplus: ➢ Collection of records produced by Chemical Abstract Service (CAS) for the patent invention in chemical field ➢ Contains re-written abstracts and human-indexed content ➢ The new basic records are added to the database, but no additional indexing is done ➢ Collection is an extended patent family EDOC/EPODOC: ➢ European Patent Organization’s Search Documentation System ➢ This family structure formed the basis of PlusPat file ➢ EPO’s internal patent examiner database ➢ EDOC first consisted of application, priority and publication numbers. EPODOC then added abstracts, titles, inventors and applicants 4 | © Ingenious e-Brain Solution 2019. All rights reserved. | [email protected] | www.iebrain.com
