Kyocera Int'l, Inc., 835 F.2d 1419, 1423, 5 USPQ2d 1194, 1198

there is an inherent disclosure that the housing has an
opening permitting the product (i.e., paper towel) to be
dispensed, there is nothing in the application to suggest that
the opening be in the bottom front portion of the housing as
set forth in the above-noted limitations from claims 12 and
16. In that regard, we note that a disclosure that merely
renders the later-claimed invention obvious is not sufficient
to meet the written description requirement; the disclosure
must describe the claimed invention with all its limitations.
