DPCI OVERVIEW • WHAT ARE PATENT CITATIONS?

• WHY SHOULD YOU BE INTERESTED IN THEM?

• WHAT IS DPCI?

• WHY SHOULD YOU USE DPCI?

What is a citation? • In the context of patents, a CITATION is a reference to a

previous work which is relevant to the current patent application – Citations can be provided by the assignee (often referred to as

inventor citations), the patent examiner or sometimes third parties (typically people who are opposing the patent)

– They are documents the examiner is going to look closely at to establish the novelty of the invention

– Some provide useful background information (prior art) whilst others can be considered to be potentially novelty destroying

– All of them will involve closely related technology

• The cited document may be a patent or a non-patent publication (e.g. a journal article)

Each patent can have 2 types of citation

Cited (older patents) Citing (more recent patents)

Master Patent

Time

2 types of citations exist for a patent • The cited patents (and non-patent literature)

– These are older documents the patent references – They are listed either as part of the bibliographic data or

the search report (see next 2 slides) – They may be novelty destroying for the patent application

you start from

• The citing patents – These are more recent documents which cite the patent of

interest – They can only be identified by searching patent citation

databases such as DPCI – They identify people working in closely related areas to

the patent of interest

• WHAT IS DPCI?


Why should you be interested in them • Finding additional related documents to the ones in your search

– Including all citations (forward and backward) of the documents found in your search can find additional relevant documents which did not include your search terms

• Identifying key documents in a dataset or portfolio – Patents which receive a lot of citations (especially if they have been

granted) are often highly valuable patents

• Identifying key competitors & licensing opportunities – Anyone who is citing a lot of your patent is a key competitor – It is also possible they may be interested in licensing your patent if

they are potential infringers

• Protecting your own patents – Any patent which cites yours is a potential infringer which you need to

be aware of



• WHAT IS DPCI?


WHAT IS DPCI?

• A Value Added Patent Citation Database with both Patent & Literature Citations

• Family based and updated weekly – 11+ million families/inventions – De-duplicated citations from across all DWPI family members

• Complementary to DWPI – Shares common accession numbers – Includes DWPI titles, Assignee Codes/Names

• Access to DPCI – File DPCI on STN

Derwent Patents Citation Index

• The DPCI record is in 3 parts, comprising details of: – The master patent family – Cited (older) patents and literature – Citing (more recent) patents

• Like DWPI, the records are arranged into patent families, including for citations

• Records in DWPI and DPCI share the same accession no. – Useful for efficient cross-filing

• The DPCI record is updated when any new cited or citing patent information is received – e.g. from equivalents

Patent Citations • Drill down to most

relevant citations – E.g for protection, licensing

By: E = Examiner

I = Inventor

O = Opposition

T = Third party


• WHY SHOUOD YOU BE INTERESTED IN THEM?

• WHAT IS DPCI?


DPCI HAS FAMILY BASED CITATION DATA • DPCI collects together all the citations for a

particular DWPI patent family (invention) in one record – No need to look up citations of each patent in the family

separately – all the citations are in one place – a huge time saver

– The Citations of the individual patents are de-duplicated (see next 2 slides)

• Record can be accessed via any patent family member or via the DWPI accession number

DWPI family • Some do not have citation information • Those that do all have unique citations

Some other useful fields • DPCI includes the IPC or national class searched by the

examiner for a particular invention (/RPIC or /RPCL) – Search for all patents an examiner search a particular class for – You can see which class an examiner searched for any given

invention - this lets you get into the mind of the examiner (field CITN) • Understanding how they looked at key competitors patents will help you

identify areas they have not looked into – useful when opposing documents

• Also by looking at similar inventions will give an indication of how yours will be treated

• Citation counts are broken down by various fields – For instance by source (examiner, inventor, opponent etc.) – By authority – By patent or by accession number

10

Original document of the invention

11

Basic steps to find patents related by citation

• To find related patents starting with a patent number:

=> FILE DPCI => S WO2000065014/PN (produces answer set L1) => FILE WPINDEX => TRA L1 1- OS.D OS.G /AN (produces L2 and L3)

L3 contains the DWPI records for all cited and citing patents

Note: Although PN.D and PN.G would work just as well as OS.D and OS.G (L3), using Accession Numbers is usually more efficient, since there is only one Accession Number per patent family.

Search Question: Which are the key patents of Henkel in the area of detergents/washing?

Identifying key patents using citation counts

Note: In this example we use the Other Source Count Citing (OSC.G) analysis field. The “Other Source” is the citing DWPI Accession Number (AN). OSC.G is therefore the number of citing DWPI ANs – e.g. the number of citing DWPI patent families.

Search Question: Which competitors cite Colgate Palmolive inventions the most since 2006?

Identifying competitors using patent citation data

How to identify competitors

• To analyze the organizations developing inventions in the same area as your company:

=> FILE DPCI => S your company /PA.D, /PACO.D NOT your company /PA, PACO (produces L1) => ANALYZE L1 1- PAX PACO (produces L2) => D TOP 10 PACO => D TOP 10 PAX

This gives a listing of the Top 10 organizations most frequently citing your company’s patents by Assignee Code (PACO) and Assignee Name with Code (PAX)

31

Option: use citation categories to find the most closely related cited patents

• For example: identify patents very closely related to those of your company => FILE DPCI => S your company/PA.D (P) (X OR I OR Y)/CAT.D Retrieves records where closely related patents cite patents from your company. Use this to check for the closest competitive relationships between documents.

Note: DE, JP and US patents do not use citation categories (relevancy indicators).
