1268, 20 USPQ2d 1746, 1749 (Fed. Cir. 1991). "Inherency,
however, may not be established by probabilities or
possibilities. The mere fact that a certain thing may result
from a given set of circumstances is not sufficient." Id. at

However, upon our careful review of Katsumata, we
fail to find that the Examiner has established that the
evidence makes clear that the missing description of
converting the double rate signal into a signal having the
same format as that of a high definition television signal is
necessarily present in the circuit described in figure 11 of
Katsumata. We are left instead with dealing with
probabilities and possibilities. In column 14, lines 37
through 51, we note that Katsumata teaches that a double
scanning speed conversion circuit 1103 performs movement
adaptation scanning line interpolation. Furthermore,
Katsumata teaches in this same portion of the specification
that the system includes a display 1104 having an aspect ratio
of 16:9 which is able to be in synchronism with the double
