  • Could you link the patent document? It looks like, if it were granted, it would expire in 2021...

  • Pair shows the 371(c) date as 05-23-2001. However, it also seems to claim priority to a provisional filed 11-13-1995. "This application is a continuation in part of application Ser. No. 09/792,323 filed Feb. 23, 2001, now U.S. Pat. No. 7,340,506, which was a continuation-in-part of application Ser. No. 08/879,958 filed Jun. 20, 1997, now U.S. Pat. No. 5,987,500 which was a divisional of application Ser. No. 08/700,726 filed Aug. 5, 1996, now U.S. Pat. No. 5,778,178 which was related to and claimed priority from U.S. provisional patent application No. 60/006,634 filed Nov. 13, 1995."

    The fact that there are so many continuation-in-parts is why this is more interesting then other questions of this type.

If field (22) is 2001, and it is not a continuation from a previous patent, than add 20 years + 551 days to 2001 and you have your date.
