Appeal No. 1999-0880
Application No. 08/700,610
because each one of the prior art rejections relies, at least
in part, on Early and we find Early to constitute nonanalogous
art. Early is applied by the examiner for a teaching of a
non-user-changeable code, the examiner concluding that it
would have been obvious to have modified the primary
references, allegedly disclosing user-changeable code, in
order to provide for a plurality of transmitters with non-
user-changeable codes.
Early is directed to a key which is “coded” in an optical
manner so that when the key is inserted into a lock, a
correctly “coded” key will unlock the lock. The “coded” key
comprises light reflecting means on the key. When the key is
inserted into the lock, these light reflecting means are
located in the path of a laser beam and, if the key is a valid
one, light reflected back to a unique pattern of photo-diodes
will cause the lock to be unlocked.
Early is not directed to anything related to garage door
opener systems or to controlling a position of a barrier, as
claimed. Early does not employ radio frequency signals nor is
Early directed to a remote control of an object since the
“coded” key in Early must be inserted into the lock.
