"Not sure precisely when the US switched to 20 years from filing, but by the late 90s at the least." "Effective June 8, 1995, as a result of a law signed by President Clinton in December, a United States patent will expire 20 years after its filing date. The law, passed to implement the General Agreement on Tariffs and Trade (GATT), applies to all patents issuing on applications filed on June 8, 1995 or later. If a patent issues on an application claiming the benefit of the filing date of one or more previous U.S. applications, the twenty years is measured from the earliest filing date in the chain. (The international filing date of a Patent Cooperation Treaty application designating the United States - which might typically be filed by an applicant outside the U.S. prior to filing here - counts for this purpose as a U.S. application filing date.)" bromsun.com This implies U.S. Utility Patents filed on or before June 8, 1995 expire 17 years after the issue date.
