TEVA patent expir Sept 2015

Maybe:
The longer of (a) 20 years after the May 22, 1995 filing date on patent 5800808 or (b) 17 years after the issue date of Sept. 1, 1998, despite what the OB says.

I do not know how but two of the nine divisional patents are not in the Orange Book. US 5800808, which is not in the Orange book, has an expiry date of September 2015 (also not clear to me how is the calculation).
