Guide to Downloading Patent Copies (PDF, TIFF)

Update [2009.09.16].  After all these years this post still gets a lot of traffic.  Many of these services have come and gone so I thought I’d at least let my readers know what I am currently using (the rest of the Guide follows):

  • Google Patents — Allows you to download PDF copies for free.  Just look for the “Download PDF” button on the left side.  Google’s PDFs are nicely compressed…very small.
  • If Google doesn’t have it (Google is a little out of date), I use PatentFizz.
  • If I need a foreign patent, I first see if I can get it on esp@cenet.  Find the document, click on the “Mosaics” tab, then the “Save Full Document” link.



The USPTO has never provided the ability to download multiple page TIFF or PDF copies of patents/patent applications.  Thankfully, a number of web sites and computer programs have stepped up to fill that void.

II.  Programs/Plug-Ins

a.  PAT2PDF.  If you don’t mind installing a “Linux-like environment for Windows” and doing some tinkering, you can configure a FREE package for downloading copies of patents to your computer using Canadian attorney Peter Eliopoulos’ instructions.  I have tried it and it does work.  Did I mention the word FREE?

VI.   Notes:

a.    A reader reminds us that “As you probably know, the USPTO sets a limit on how many patents one can download in a given time.  Some years ago they blocked me because I exceeded their quota.  I assume that this policy is still in effect, although I haven’t checked it.  If it is, you may wish to caution your readers.”
