Patent family & Data Sources
A patent is a set of exclusive rights given to creator/inventor to exclude others from
making a duplicate copy of his/her findings viz. to exclude others from selling, making
and using for limited time (usually 20 years). Patents can be granted in different
countries, each having slightly different rules or legal formalities. Now if one wants to
have legal protection over his invention in multiple countries, it would require him to file
multiple patents for each country or region. It may cause duplication, to avoid this
duplication, a concept of patent family was introduced to reduce multi-national results of
one invention. Therefore, a group of patent documents that share same inventive
concepts and technical details is known patent family. The basis of creation of patent
families is the shared priority data so that all patent documents that are to be included in
family are technically equivalent.

The artificial patents in the PATSTAT database: how much do they matter when computing indicators of
internationalisation based on worldwide priority patents?

Patent family & Data Sources
Data Sources:
INPADOC:
➢ International Patent Documentation Centre was founded in 1974 by an agreement
between Austrian Patent Office and World Patent Organization. Its purpose is to
collect and document patent families
➢ A new family member must share at least one priority document with at least one
other patent in the family. Therefore, a document’s INPADOC patent family means
that it is an extended patent family
➢ To reduce the re-classifying of older records, EPO worked on older documents
without proper priority data, associating them using inventor and subject matter
information to create artificial patent families
➢ Due to their extensive family building rules INPADOC families can become quite
large, chemical and biological subject fields tend to generate largest INPADOC
families

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
5 | © Ingenious e-Brain Solution 2019. All rights reserved. | services@iebrain.com | www.iebrain.com
Patent family & Data Sources
➢ In 1990 EPODOC was merged to INPADOC to serve internal database. Questel re-
launched the commercial version of EDOC as PlusPat
➢ It uses INPADOC as the source.
FamPat:
➢ It is a simple patent family database
➢ It is enhanced with key contents like:
➢ Object of invention
➢ Advantages of the invention and drawbacks of the previous one
➢ Independent claims
➢ It includes EPO’s family rules along with the enhanced contents
➢ It also includes: First page information, Classification nodes, Patent and non-
patent literature citations, Full specifications, claims and detailed legal status
information
PlusPat:
➢ It is precursor to FamPat database
➢ It grouped all the publication stages of a patent at one place. It therefore prevents
duplication
➢ It is also known as the domestic patent family
PatBase:
➢ It takes aggregated family data as the meta-record
➢ Instead of indexing it focuses on loading full text data of an individual publication
record to increase the chances of being found on search
➢ It uses extended INPADOC patent family
Esp@cenet:
➢ Used to provide representative family members that constitute entire family
record in English wherever possible
➢ To search for equivalent records from other countries to match the technical
content of the record undertaken

It may cause duplication, to avoid this duplication, a concept of patent family was introduced to reduce multi-national results of one invention. Therefore, a group of patent documents that share same inventive concepts and technical details is known patent family. The basis of creation of patent families is the shared priority data so that all patent documents that are to be included in family are technically equivalent. Simple patent family Complex patent family Extended patent family National patent family Domestic patent family Artificial patent family Patent Family

At least two of which are distinct from each other and at least one originating application in common with the other members of the family Same country of publication with procedural publications for the same originating application At least some of which do not share a common originating application or applications Related document with multiple priorities is not allowed into the family Multiple priorities are not allowed into the family unless it shares priority number common to all the other members All related documents sharing at least one priority member shown in the list above may enter the family At least two of the published patent documents are a result of additions, continuations, continuations-in- part, or divisions of the original subject of invention It grouped together all the publication stages of a patent in one place. It therefore prevents duplication. Members of this type of family are determined only after intellectual investigation to have essentially the same disclosed content 1 Patent Families 2 The artificial patents in the PATSTAT database: how much do they matter when computing indicators of internationalisation based on worldwide priority patents?

All rights reserved. | services@iebrain.com | www.iebrain.com Patent family & Data Sources Data Sources: INPADOC: ➢ International Patent Documentation Centre was founded in 1974 by an agreement between Austrian Patent Office and World Patent Organization. Its purpose is to collect and document patent families ➢ A new family member must share at least one priority document with at least one other patent in the family. Therefore, a document’s INPADOC patent family means that it is an extended patent family ➢ To reduce the re-classifying of older records, EPO worked on older documents without proper priority data, associating them using inventor and subject matter information to create artificial patent families ➢ Due to their extensive family building rules INPADOC families can become quite large, chemical and biological subject fields tend to generate largest INPADOC families 5 6 7 8 1 2 3 4 Data sources INPADOC EDOC PlusPat PatBase DWPI CAplus FamPat Esp@cenet

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

Questel re- launched the commercial version of EDOC as PlusPat ➢ It uses INPADOC as the source. FamPat: ➢ It is a simple patent family database ➢ It is enhanced with key contents like: ➢ Object of invention ➢ Advantages of the invention and drawbacks of the previous one ➢ Independent claims ➢ It includes EPO’s family rules along with the enhanced contents ➢ It also includes: First page information, Classification nodes, Patent and non- patent literature citations, Full specifications, claims and detailed legal status information PlusPat: ➢ It is precursor to FamPat database ➢ It grouped all the publication stages of a patent at one place. It therefore prevents duplication ➢ It is also known as the domestic patent family PatBase: ➢ It takes aggregated family data as the meta-record ➢ Instead of indexing it focuses on loading full text data of an individual publication record to increase the chances of being found on search ➢ It uses extended INPADOC patent family Esp@cenet: ➢ Used to provide representative family members that constitute entire family record in English wherever possible ➢ To search for equivalent records from other countries to match the technical content of the record undertaken
