Xeni Jardin:
Link to Google Patent Search beta. Instant favorite new timehole. Fascinating, and infinitely better than the USPTO website (all data comes from USPTO, and results on Google do include links to the USPTO entries). No foreign patents for now, it seems, just US. Doesn't work for me in Firefox 2.0 on Mac, but IE and Safari in many variations seem to work just fine, and Firefox on PC or earlier iterations of Firefox on Mac may as well.
