Data availability and limitations

Data sources

Primary Source

– National and regional patent office – International organisation

Secondary Source

– Commercial data provider – National and international public institutes

Limitations

Difficult to access standardised data for statistical purpose Limited metadata / methodological weakness 4

Patent statistics activities at the OECD

Complementary to existing efforts International statistical infrastructure Taskforce - EPO, JPO, USPTO, WIPO, EC, NSF &

OECD

Database

– EPO, USPTO, Patent families – National offices (e.g. JPO), citations, PCT (on going work) – Firm level data (on going)

Methodology

– Counting procedure, families, technology, industry, citations, firm level data

Understanding patent indicators

Wide-ranging indicators: conflicting / misleading

messages

Understanding patent indicators and what they reflect

– Designing indicators to measure a particular phenomena

Methodological choice for calculating indicators

– Geographical distribution – Reference date – Multiple inventors

Dissemination

Improve accessibility of data / metadata Current OECD practice

– Various OECD publications (e.g. Compendium) – CD-ROM for the TF members, test users, on request

Online access

– www.oecd.org/sti/measuring-scitech – EPO / USPTO / Triadic patent families – Covers more than 100 countries – Reference date (application / priority / grant) – Reference country (inventor / applicant) – IPC / US patent class – International co-operation
