In the US, for patents filed prior to June 8, 1995, the term of patent is either 20 years from the earliest claimed filing date or 17 years from the issue date, whichever is longer. So, for the three Apple patents, this means that this is when the patents expire: US5155805 : 2009-10-13 (17 years from issue date: 1992-10-13) US5159668 : 2009-10-27 (17 years from issue date: 1992-10-27) US5325479 : 2012-05-28 (20 years from file date: 1992-05-28) So, two of them will expire this October, but the last one won't go out until May 2012. ~spot -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
