When US 6160029 issued, it indicated that it was based on a cip of four US
provisional applications: 123813 and 123814 of 3/11/99; and 126887 and
126888 of 3/30/99. However, 126888 turns out to be the underlying
application for WO200058785 to Concord Camera (+ EP1166177; AU200040208),
rather than a Dow invention. A check of the PAIR page shows that US6160029
is indeed derived from provisionals 123813 and 123814, but NOT from 126887
or 126888. I have no idea what 126887 might have been; it shows up in no
database so far as I can tell. Yet the incorrect priorities still show for
this patent on the USPTO website.
Is it my imagination, or has there been a deterioration in quality of
biblio in recent years? Meanwhile, this should be fixed.
