I think you can do a reasonable class/sub class search using the USPTO web site, but IMO the text searching facilities available from the USPTO web site are completely inadequate. I don't think you can do a reasonably effective/efficient search using simple boolean expressions.

Would anyone recommend using Delpion or micropatent sites? I'm finding the USPTO website to excel spreadsheet method to be too time consuming.

I do all of my searching with Micropat. Its search operators offer better resolution than the PTO's in searching. Plus you can search foreign patents.

Sue, all the above responses seem to be generally useful comments- however, since I spend nearly all of my time doing patent searches in all types of subject matter, here are a few of my own tips:
1) use the US Patent database at uspto.gov with any of the indices given there, especially, the US classification index either alone or combined with keywords;
2) become familiar with the relevant classes in the USCS (US Classification System) that include your subject mattter, e.g., Classes 600-623 for medical devices; look over the schedules and the definitions to those classes as well;
3) use the EPO database at ep.espacenet, which includes EP, WO, US, JP, and about 30 or so other domestic patent document database, with the ECLA (European Classification) designations - the ep.espacenet opening page lets you access the ECLA system on the left of the page (under "classification search" hyperlink) - if you find relevant EP or WO documents, review any search report that may be avaiilable with the document image
4) become somewhat familiar with ECLA, e.g., Section A, Class 61 for medical devices - there are no separate "definitions", but the schedule does give notes for various parts of the schedule
5) use the JPO patent database /www.ipdl.ncipi.go.jp (choose english version at top right if you can't read japanese) to locate relevant Japanese documents, using either the IPC (International Patent Classification, corresponding somewhat to the ECLA designation, but may need to be selected from outdented schedule entry), or the Japanes Classification System (this may take a little while to learn), or key words
performing these five steps will generally give you a fairly good coverage of global patent documents
of course, if any of the US patents are relevent, you will probably want to look at documents cited in those patents, such as on the front page or in the Background sectiion of the patent
take care,

Fran, post whatever you want, but I'm not sure a response to a month old post from someone who was only here as a "Guest" is reaching the intended audience.
