My guess if you are using keywords as a strategy that you will get a better retrieval with Derwent. Derwent is more likely to put relevant keywords in their abstract than would appear in the abstract on the original document. The PCT web site only covers PCT patents. The EPO site, esp@cenet, covers lots of issuing authorities, but their search engine is primitive.

Nancy Lambert has commented more extensively on this very subject of free vs. value added search services. Check the archives of the PIUG list.

I recently did a search for a large company (mechanical art)
to locate all their PCT and EP applications and patents from 1998 to present dealing with a specific 4 keywords "ORED" together. I did it in Derwent on Dialog. I found 28 records.

After giving it to the atty., it was suggested that I attempt to do this type of searching on the PCT & WIPO websites in the future, to save clients $$.
I will be hanging out on those sites over the next several days to see if, in fact, this is do-able.
But, figured someone from the PIUG might have more familiarity with these web offerings and might want to offer some caveats, if applicable.
Your comments are most appreciated.
Thank you.
