Ah, I left one off the list. The fifth one, 5,442,758, is the old
one which should have died on its own in any case.

DISCLAIMER: You should neither take any actions nor refrain from any
actions based on this information.
U.S. Patent No. 5,442,758 was issued on August 15, 1995. Its
application was filed July 19, 1993.
Utility patents issuing from applications that were pending on June 8,
1995 (based on its actual filing date)
have a term measured by the longer of 17 years from the date of issue
or 20 years from the date of U.S. filing
(of the earliest non-provisional application in its chain of
parentage). See e.g., the Manual for Patent
Examination Procedure (MPEP), section 2701, or 35 U.S.C. 154.
Accordingly, it looks like this patent (No.
5,442,758) expired July 19, 2013.
Regards,
Ian Fink
