I have a made a CD containing a large collection of puzzle patents in pdf form gathered from various patent sites. Tom mentioned it on the DCD2004 thread
(thanks Tom), and posted these two screenshots:
Jackpot patent screenshot
Preview Images screenshot
It has a viewer, which lists the 700 patents under various keywords, shows preview images of the patents, sorts the patent list by name / date / inventor / description, and allows you to jump from one patent to any other in the database that it references or is referenced by.
As a bonus, the CD includes a copy of my complete website.
I am selling copies of this CD for a mere $15, including worldwide postage.
I accept PayPal payments on my yahoo.com email address (jaapsch@..), or you can contact me through a private message to arrange things.
