You can access all these applications by doing a number search. The B2 database will present a Bibliographic page for that patent family. This page has a number of fields, which are, the requested patent, the patent {presented}, and equivalent {patent application} fields. Click on the quivalent or requested patent button, this will access the B3 database and retrieve the original filing and displays this in PDF format, readable by Acrobat Reader.

In determining the choice of the reference document in English, the EPO selects them based on the following selection order, the EP document in English, then the first US document published, then the first GB document published, etc.

Also when viewing EP applications, if the SR button is present then the search report for that application is also available. If not try the B3 database as that might have the search report.

We can enter multiple keywords and IPC marks and generate a search result listing. We can look at the abstracts and then immediately go and look at the full text of the patent. This site, the USPTO & IBM would seem to be the sites of choice for patent searching on the web.

The EPO now provides a European Patents Server which supplies whole PDF documents for EP Applications from January 2004 ~EP1,200,000.
