Nice patent display tool

If you're like me and you look at a lot of patents... here's a tool I recently discovered for viewing and printing patents: http://www.pat2pdf.org

The USPTO (US Patent and Trademark Office, http://www.uspto.gov) has scanned images of all the US Patents available on line, as well as an online patent search database for all patents after 1976.

That's great, but all the patent scans are in TIFF format.  TIFF format is used by graphic artists, and is apparently what patent offices use to share scanned images internationally, but most browsers can't handle TIFF formatted images, or require a plugin to display the images, and the plugin may not print out the images very well.  The European Patent Office web site (http://ep.espacenet.com) displays patents in PDF format, but it only works a page a time.

pat2pdf solves this nicely.   You browse there, enter a patent number and it runs a little script that:

  • looks up the patent
  • downloads the TIFFs for each page
  • converts and compiles them to a single PDF file
  • downloads and displays the PDF file

Here, try it out on the recent Microsoft patent, US 6,754,472 "Method and Apparatus for Transmitting Power and Data Using the Human Body".

Or US 6,368,227 "Method of Swinging on a Swing" (!!!).

This is a great tool. May I add patent, 6,796,396, some enhancements to the Segway personal transporter! No, it's not a scooter! ;-) It was was of the most memorable experiences of my life, getting to ride a Segway, and not falling off! I can't wait to do it again.
