*A communication from the examiner should have been received in most
applications filed prior to this date.

Patents will Expire as Follows:
(1) The term of any utility or plant patent that is in force on or
results from an application filed before June 8, 1995 is the greater of
the 20 year term provided in 35 U.S.C. 154(a)(2) or 17 years from
grant subject to any terminal disclaimers. 35 U.S.C. 154(c)(1).
(2) All utility and plant patents granted on applications having an
actual United States filing date on or after June 8, 1995 are granted for
a term which begins on the date on which the patent is granted and
ends 20 years from the date on which the application was filed in
the United States. If the application contains a specific reference to
an earlier application under 35 U.S.C. 120, 121 or 365(c), the patent term
ends twenty years from that date on which the earliest application was
filed. 35 U.S.C. 154(a)(2).
(3) All design patents are granted for a term of 14 years from the
date of the grant.
However, the term of any patent may have been curtailed by disclaimer
under the provisions of 35 U.S.C. 153, have lapsed due to failure to pay
maintenance fees, or have been extended under the provisions of 35 U.S.C.
154, 155, or 156. Thus, if more reliable information is needed with
respect to a particular patent, then the specific patent file should be
reviewed to determine the actual date of patent expiration.
