Review for PatentlyUseful(tm) Patent Application Number Search Engine by Patent Attorney
Rated 5 out of 5 stars
Just like the patent version, this is a fantastic search engine for anyone working with patents- this is the fastest way to pull up the text of a published application. If you set the keyword (under "Manage Search Engines...") to "pa", you can find published app no 20040123456 by going to the location bar (or typing Ctrl-L) and typing "pa 20040123456" and hitting enter. Amazing!
