Sadly, the patent granted is a continuation of one originally filed in July 1984. The prior art has to pre-date a year before the filing time, apparently. The newer patent was granted in 1988. I don't understand continuations, but wearing my Glasses of Cynicism +5, their effect seems to be to allow you to file a patent before you actually know very much about what you are trying to patent, in order to pre-date any prior art... then to add the necessary details later. Nice if you have the necessary money (and lack of scruples). -- [email protected] ANU Supercomputer Facility Data Grid Programmer Leonard Huxley Bldg 56, Mills Road Ph: +61 2 6125 5449 Australian National University Fax: +61 2 6125 8199 Canberra, ACT, 0200, Australia ----- FAQ and OpenGL Resources at: http://www.geocities.com/SiliconValley/Hills/9956/OpenGL -- Author: Jason Ozolins INET: [email protected] Fat City Hosting, San Diego, California -- http://www.fatcity.com --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [email protected] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB OPENGL-GAMEDEV-L (or the name of mailing list you want to be removed from).
