A scam! Don't waste your time! Deserves no star!

Can't do Boolean search so multiple words searches yield many irrelevant results...

Interesting; Needs work

Inventor search pulls up many patents not by that inventor. Keyword search found a patent of interest, but when I tried emailing the PDF to myself I found that it attached the 32 pages as 32 separate PDF files. Some email servers cannot handle that many attachments. It should assemble all the pages into one PDF file before attaching.

Good effort

It would be very helpful to search for terms in the claims.

If previous reviewer's comment about separating PDFs into pages is true that would very problematic for most users
