Where can we search Patents?
• “Back in the old days”:
– Directly in the National Patent Libraries
– By looking through Official Patent Bulletins
• In more modern times:
– First Commercial Databases, direct modem connection (no internet), paid by time and/or results
– Patent stored on Compact Discs (retrieval via CD Towers)
• Nowadays:
– Everything available on Databases via Internet! Mostly flat rate pricing, and lots of public free databases available!

Patent Databases
• We can distinguish:
– Public Patent Databases (mainly offered by the
national patent offices)
– Commercial Patent Databases (offered by Database
Hosts)
“TOP PLAYERS”:
• THOMSON INNOVATION
• QUESTEL ORBIT
• STN

Why using Public Patent Databases?
• Searching in most public patent databases are FREE OF COST
• Comparing to commercial databases, search and analysis
functionality of public databases have improved quite
substantially over the years!
– Alerting services
– Automatic Translation
– Search history

• Knowing WHICH public database to use WHEN can be as
effective for a Technology Watch activity as with a commercial
database (or even better!)
