**The same databases that are available in USPTO Public Search Room, near King Street Metro in Alexandria, VA. The free web databases usually are quite effective in finding what subject classification numbers to search, or in looking up small numbers of patents. But PubEAST's very fast browsing will save you a great deal of time, once you find several possible classifications and have to look through hundreds of patents in each one. PubEAST and PubWEST also allow far more complex Boolean, field, and proximity searching than you can do in the web databases.
