Based on the provided patent data for US patent 5132992, here is a detailed analysis of its term, related applications, and family members.

Patent Term and Expiration

  • Patent Term Adjustments (PTA) / Extensions (PTE): There are no Patent Term Adjustments or Extensions indicated in the legal events for US patent 5132992. The patent's term is determined by the statutes in effect at the time of its filing and issuance.

  • Projected and Actual Expiration Date:

    • Filing Date: January 7, 1991
    • Issue Date: July 21, 1992
    • Calculation: As a patent filed before June 8, 1995, and in force after that date, its term is the greater of 17 years from the issue date or 20 years from the earliest effective filing date.
      • 17 years from issue date: July 21, 1992 + 17 years = July 21, 2009.
      • 20 years from filing date: January 7, 1991 + 20 years = January 7, 2011.
    • The controlling, later date is January 7, 2011. The Google Patents data confirms this, listing an "Anticipated expiration" of 2011-01-07 and a current legal status of "Expired - Lifetime" [cite: https://patents.google.com/patent/[US5132992](/patent/US5132992)/en].
