`Petitioner’s Brown-
`Scherzer Combination
`(Pet. 25-26)
`• Modifies Brown’s system to
`include:
`•
`Scherzer-like software client on
`Brown’s mobile electronic device
`105.
`Scherzer-like provider application
`server accessible via internet.
`• Configuration data 182 stored on
`Scherzer-like provider application
`server is transmitted from device
`105 to device 101 to enable device
`101 to connect to the Internet
`• Device 101 does not include a

`103 Challenges
`• Petitioner’s Brown-Scherzer combination results in
`widespread, unfettered dissemination of access
`credentials and network access being provided to
`unrecognized devices and unregistered users
`• Petitioner’s Brown-Scherzer combination ignores
`teachings in Scherzer, as a whole, and POSITA’s
`common understandings of network security
`• Petitioner and Dr. Cooperstock have assumed
`inconsistent and unclear positions throughout this

`DEMONSTRATIVE EXHIBIT – NOT EVIDENCE
`
`Mr. Joseph C. McAlexanderIII Consistently
`Described Limits to Network Access in Scherzer
`• Scherzer’s account acceptability requirement and
`tracking precludes an unregistered device from using
`Scherzer’s system to obtain wireless access. KOSS-
`2022, ¶51-55.
`• A POSITA implementing Scherzer’s system would
`utilize security features. Id. at ¶60.
`• It would “defeat the purpose of Scherzer” if users
`could benefit from Scherzer service “while
`circumventing Scherzer’s tracking and acceptability
`requirement.” Id.
`• If registration information is “protected information,
`it would be encrypted.” APPLE-1024, 318:4-11
`(describing encryption aspects of Scherzer).
`• “Scherzer’s system would implement some means of
`restricting unregistered connectivity… such as by
`MAC filtering” which was known to a POSITA. KOSS-
`2022, ¶57-58.
`

`
`

`

`DEMONSTRATIVE EXHIBIT – NOT EVIDENCE
`
`Dr. Cooperstock’s Inconsistent Characterizations
`of Limits, If Any, to Network Access
`• “Scherzer does not prescribe any limits to what
`kind of users, either registered or unregistered,
`can make use of the service.” APPLE-1025, pp.
`74-75.
`• It would “defeat the purposes of Scherzer to
`limit what devices or how many devices a user
`can connect to access points.” Id.
`• Scherzer does not prohibit sharing credential
`information between users and “the [Brown-
`Scherzer] combination that I described does not
`preclude that either.” KOSS-2023, pp. 16-17.
`• But, compare:
`• Concerns of widespread, unfettered dissemination are
`“not relevant” and “mischaracterize[]” two examples
`where network access is only shared between two
`commonly-owned devices of a registered user. APPLE-
`1023, ¶¶ 57, 25.

`

`Consequences of Broad
`Scope to Petitioner’s
`Brown-Scherzer
`Combination
`• Network access is provided to device
`101, which can be associated with a
`different user than device 105
`• Network access by device 101
`obtained with Scherzer’s system is
`not tracked
`• No limits to further dissemination of
`access credentials to other devices
` Device 101 freeloads; incentive for
`registering with Scherzer’s system
`destroyed (KOSS-2022, ¶¶ 49, 55, 58)
` Registered users lose control of their
`wireless access points; users would
`forego registration (Id. ¶55)

`• Petitioner’s Brown-Scherzer combination fails to consider
