Term, Related Applications, and Expiration

• Patent Term Adjustments (PTA) / Extensions (PTE):

  • There are no Patent Term Adjustments (PTA) or Patent Term Extensions (PTE) for US Patent 5,359,647.
  • The provisions for PTA were established by the American Inventors Protection Act of 1999 and generally apply to applications filed on or after May 29, 2000. Since this patent was filed in 1993, it does not qualify for these adjustments.

• Continuation and Divisional Applications:

  • There are no continuation or divisional applications associated with US Patent 5,359,647. The patent record shows it is an original application that does not claim priority to any earlier non-provisional US applications.

• Patent Family Members:

  • US Patent 5,359,647 is part of a small patent family based on its priority application, US08/069,294. The family members include:
    • WO1994028666A1: A World Intellectual Property Organization (WIPO) publication from the PCT (Patent Cooperation Treaty) application.
    • AU6957994A: An Australian patent application.

• Projected Expiration Date:

  • The patent is Expired.
  • The projected expiration date was May 28, 2013.
  • Calculation: This patent was filed on May 28, 1993, which is before the GATT (General Agreement on Tariffs and Trade) implementation date of June 8, 1995. For patents filed before this date, the term is the longer of 17 years from the issue date or 20 years from the earliest non-provisional filing date.
    • 17 years from issue date (Oct 25, 1994) = October 25, 2011.
    • 20 years from filing date (May 28, 1993) = May 28, 2013.
  • The longer term applies, resulting in the May 28, 2013 expiration date. This is confirmed by the "Anticipated expiration" date listed in the patent's legal status information provided in the source text. The patent's legal status is "Expired - Lifetime," indicating it completed its full statutory term and was not terminated prematurely for reasons other than a temporary lapse in maintenance fee payment (which was later reinstated).
