Patstat beyond Europe

An insight into Patstat data from patent authorities other than EPO

By Gianluca TarasconiMadrid, 9/12/2010

What is PATSTAT

PATSTAT stands for EPO Worldwide Patent Statistical Database.

Contains a snapshot of the EPO master documentation database (DOCDB) which contains data of about 90 national and international patent offices with different degree of coverage.

Data include bibliographic data, citations and family links. This database is designed to be used for statistical research and requires the data to be loaded in the customer's own database.

Non EPO data vs APE-INV Name Game

Data from other patent authorities may help in:

Validate algorithms against other spellings/conventions;

Fill missing/correct data (FI address/city) using data from equivalents;

Use Patent Family(1) data to improve algorithms using other data to give a similarity score;

(1) For a list of patent family definitions see : C. Martinez Insight into Different Types of Patent Families, STI Working Paper 2010/2

6 different spellings for name, 3 different addresses

In this case name and city are better parsed in US equivalent patent data;

Example (II): inpadoc family # 88, Mr Newman

WO patent data confirm that correct address is 43111 Robbins street

What dimensions are relevant

8

A) data coverage (% of coverage by year)

Are data from patent authority X 100% included into Patstat from year W to year Z ?

B) Data transmission delays

How long does it take a non EPO patent to reach in PATSTAT?

C) Completeness of geographic data

How is quality (and coverage) of address / city / country code ?

Data coverage (I)

9

EPO gives partial informations

http://www.epo.org/patents/patent-information/data-quality.html

http://www.epo.org/patents/patent-information/raw-data/useful-tables.html

Total number of applications is given but not the % of total (EPO gives what it gets)

Data coverage (II): example on India

In patstat are reported from EPO 66219 Indian applications

Indian Patent office reports 28.882 applications filed only for 2006

Data Transimission delays (I)

We study time series 2003- 2008 for BR, CN, JP, DE, KR and IN compared to EP;

Graph differences suggest publication lags and data transmission lags differ from country to country;

Timeseries may also highlight ‘holes’ or changes of population (FI USPTO from 2000 onward)

Completeness of geographic data

Table for the TOP 20 by inventor count;

13 authorities have more than 80% of records with no country code;

12 authorities have 0% of address/city;

Anyway in many cases address data are inside first name field (FI: DE)

Conclusions

Non EPO have coverage, quality and ‘spelling’ that may change a lot from patent authority to patent authority;

Data can be used as addictional source of information but not as main source (BONUS not MALUS);

EPO could probably improve quality of this data, especially add more addresses (FI in april 2011 will release WO address data) is up to users demand more on this topic.
