accordance with a desired algorithm (col. 3, line 68, to
col. 4, line 7). The receiver can be placed in a "learning
phase" where the key code word of the receiver is reprogrammed
by the next code word transmitted to the receiver from an
arbitrary transmitter (col. 1, lines 47-57). Unauthorized use
of the remote control system with a lost transmitter can be
prevented by automatically invalidating, i.e, blocking or
erasing, the basic code word portion (col. 3, lines 20-27).
As to the step of "setting a flag in a memory of an
integrated circuit upon the first time the integrated circuit
is placed in a learn mode while configured as a receiver," the
closest reasoning we find is the Examiner's statement for the
first time in the Examiner's Answer that "Lindmayer, col. 3,
line 24 implies that an equivalent to a flag must be set since
the erasing of a code is accomplished in the system dependant
[sic] upon if the code has been used (received) at least once,
here the flag must have been set in the system which was
acting in a receiving mode" (EA5). This is a broad, but fair
reading of Lindmayer. Whatever hardware or software keeps
