`
`
`INTRODUCTION
`Petitioner requests review of claims 1, 2, 5-8, 11-13, 16-19, and 22
`
`(“challenged claims”) of U.S. Patent No. 10,820,147 (Ex. 1001, ’147 patent) based
`
`on four grounds rendering the challenged claims obvious.
`
`II. THE ’147 PATENT
`The ’147 patent was filed February 12, 2020. The earliest priority date listed
`
`on the face of the ’147 patent is October 4, 2001.1
`
`The ’147 patent is directed to providing navigation information to a user via
`
`a wireless communications device, as shown in Figure 82 below. ’147 patent,
`
`Abstract, 101:10-27; Michalson, [0028]-[0029].
`
`
`1 Petitioner relies on this date, but reserves the right to challenge it.

`
`
`
`
`’147 patent, Fig. 82. The ’147 patent allows or prohibits tracking the mobile device
`
`based on “preference flags,” which “provide a user control” to have location sharing
`
`“activated/deactivated/semi-active for privacy reasons.” Id., 6:41-45.
`
`III. LEVEL OF SKILL
`A person of ordinary skill in the art (POSA) would have been someone
`
`knowledgeable in mobile communication devices and mobile navigation systems.

`
`That person would have at least a bachelor’s degree in Computer or Electrical
`
`
`
`
`Engineering, Computer Science, or equivalent training, in addition to approximately
`
`2 years of experience working on telecommunications navigation and geolocation
`
`systems. Michalson, [0030]-[0034].
`
`IV. CLAIM CONSTRUCTION
`The Eastern District of Texas previously construed the term “preference
`
`flags” recited in independent claims 1 and 11 in a related patent as “two or more
`
`flags to control access to tracking of the user.” Ex. 1008, 54-55; Michalson,
`
`[0035]-[0036]. Petitioner applies this construction in this petition.

`Myr discloses a wireless communication system2 because it discloses a
`
`“system and method for real time vehicle guidance.” Myr, Abstract. Myr discloses
`
`a “real time traffic Guidance System” consisting of a CTU (Central Traffic Unit)
`
`and a plurality of mobile units, disclosed as Individual Mobile Units (IMUs),
`
`Client Mobile Units (“CMUs”), and Sample Mobile Units (“SMUs”). IMUs
`
`(Individual Mobile Units). Myr, 2:13-14; 2:50-54. All IMUs, CMUs, and SMUs
`
`are referred to as “mobile units.” Data transfer amongst these components occurs
`
`wirelessly, by “wireless RF communication.” Myr, 2:63-3:9; 5:16-24; Michalson,
`
`[0040]-[0041].
`
`Claim 1[a] 3

`
`
`CTU as the “IP Multicast 9 accomplishes the communication from CTU 10 to
`
`IMU.” Id., 5:52-53. A POSA would have understood that “RF transmissions 412”
`
`to the CTU are transmitted to an antenna connected to modem 411. Michalson,
`
`[0044]-[0045].
`
`As to the claimed first antenna to which the first radio-frequency
`
`transceiver is coupled, a POSA would have understood that modem 411 performs
`
`RF transmission 412 via an antenna. Myr, 5:55-57; Michalson, [0046]-[0048]. In
`
`excerpted Fig. 8 below, the IMU includes a “modem RF antenna (Unit 2)” (blue)
`
`in communication with the “modem (Unit 1).” Myr, 6:55-58.

`Myr teaches that the first radio-frequency transceiver (Myr’s RF transmitter
`
`modem and receiver) is configured for radio-frequency communication with a
`
`wireless communications network. Myr, 5:16-57; Figs. 1, 4.
`
`Myr’s RF transmitter modem and receiver communicate wirelessly with the
`
`CTU. Myr, 5:55-57; Fig. 4. Fig. 4 below shows modem 411 is used for
`
`“performing RF transmissions 412” and that receiver 408 receives information
`
`from the CTU as the “IP Multicast 9 accomplishes the communication from CTU
`
`10 to IMU.” Id., 5:52-57; Michalson, [0049]-[0050].

`
`
`Claim 1[c]
`d.
`Claim 1[c] requires a first processor within the wireless mobile
`
`communications device coupled to the at least one first radio-frequency
`
`transceiver programmed to: (1) receive information indicative of a location of
`
`the wireless mobile communications device and (2) generate an indication of a
`
`location of the wireless mobile communications device with respect to
`
`geographic features according to mapping information stored within the wireless
`
`mobile communications device. Myr discloses each of these. Myr, 5:16-21; 7:1-3;
`
`Michalson, [0053]-[0054].
`
`i. Myr discloses “a first processor within the
`wireless mobile communications device coupled
`to the at least one first radio-frequency
`transceiver”
`Myr’s mobile unit includes a processor, as shown in Fig. 4 below. Myr, 5:16-
`
`21.

`U.S. Patent 10,820,147
`
`
`First
`processor
`
`
`
`Myr, Fig. 4 (excerpted). The mobile unit’s “processor” (403) processes “GPS data
`
`obtained via satellite,” which is then “transmitted by means of on-vehicle modem
`
`and transmitter to the CTU.” Id., 5:16-21. Myr’s GPS data teaches information
`
`indicative of a location of the wireless mobile communications device because,
`
`from the GPS data, Myr’s mobile unit determines its location. Michalson, [0055]-
`
`[0060].
`
`ii. Myr’s processor is “programmed to receive
`information indicative of a location of the
`wireless mobile communications device from the
`wireless communications network”
`Myr’s processor 403 is receives information indicative of a location of the
`
`mobile unit because Myr discloses that “travel maps are displayed on the screen
`
`and the present vehicle GPS location can be observed dynamically on the map.”
`
`Myr, 7:1-3.

`U.S. Patent 10,820,147
`
`
`When calculating a travel route Myr “use[s] current travel times in the
`
`vicinity of the present position of a vehicle, and at the same time [uses] statistical
`
`travel times elsewhere.” Id., 9:8-10. Myr also discloses “it may be possible to
`
`obtain client vehicle current GPS locations via IP-Multicasting Multicasting
`
`confirmation protocol.” Id., 15:39-41. Thus, Myr’s mobile unit’s processor 403
`
`receives information regarding the “present position of a vehicle” (id., 2:13-18),
`
`the claimed information indicative of a location of the wireless mobile
`
`communications device from the wireless communications network. Michalson,
`
`[0055]-[0060].
`
`iii. Myr’s processor is “programmed to generate an
`indication of a location of the wireless mobile
`communications device with respect to
`geographic features according to mapping
`information stored within the wireless mobile
`communications device”
`Myr’s “Display Panel Unit 1” in the mobile unit is a “color display” on
`
`which “travel maps are displayed … and the present vehicle location GPS location
`
`can be observed dynamically on the map.” Myr, 6:65-7:2. Fig. 9 below shows
`
`Myr’s processor 403 generates an indication of the mobile unit with respect to a
`
`traffic circle on 7th Avenue (geographic features), near Lower Street.

`
`
`Id., Fig. 9.
`
`The mobile unit stores displayed mapping information in a “database” that
`
`“receives the updated information required for optimal navigation.” Id., 9:24-25.

`

`
`
`
`
`
`
`IPR2022-00442 Petition
`U.S. Patent 10,820,147
`
`
`Myr discloses that “[i]f the updated data is different from the previously stored
`
`data, then the on-vehicle database will automatically replace the old data.” Id.,
`
`9:30-32. Myr’s mobile unit “relies on estimated travel times stored in its database.”
`
`Id., Abstract. A POSA would have understood that Myr’s mobile unit stores
`
`necessary mapping information for display to a user. Michalson, [0061]-[0063].
`
`Claim 1[d]
`e.
`Myr discloses that the first processor determines user navigation
`
`information and displays user navigation information according to the location
`
`of the wireless mobile communications device with respect to geographic
`
`features and a destination specified at the wireless mobile communications
`
`device because it discloses enabling the driver to enter a desired destination,
`
`determining optimal route to reach the destination, and displaying the route. Myr,
`
`7:3-6. Myr discloses that the “driver enters the desired destination point DP2 and
`
`may specify route preferences by selecting the shortest Travel Time (option 3) or
`
`shortest Travel Distance (option 4).” Id., 7:3-6. A “route-planning algorithm
`
`calculates the optimal route while using multilevel map database (Unit 3),
`
`requesting travel times for various sections from the section travel time managing
`
`algorithm in Unit 9 … , and using the returned section travel times for further
`
`processing.” Id., 6:44-46. The “shortest route calculated … is transformed into a
`
`required form (signs to be shown on a map, or audio directions) and communicated
`
`

`
`to the display unit in Unit 11.” Id., 5:50-53. This determination is done by the
`
`processor in the mobile unit. Id., 5:47-53; Michalson, [0064]-[0065].
`
`Claim 1[e]
`f.
`This claim limitation requires that the first processor further sends the user
`
`navigation information to the network as a number of segments, wherein (1) at
`
`least one other processor outside the network updates the user navigation
`
`information in conformity with traffic congestion information accessible to the
`
`at least one other processor outside the network by computing a numerical value
`
`for the segments corresponding to the expected time to travel through all the
`
`segments, (2) updates the user navigation information in conformity with the
`
`numerical values for the segments, and (3) sends the updated user navigation
`
`information to the wireless mobile communications device. Myr teaches these.
`
`Myr discloses that at least one processor outside the network updates the
`
`user navigation information in conformity with traffic congestion information
`
`accessible to the at least one processor by disclosing a “Guidance System, which
`
`is capable of providing [an] optimal route from the present position of a vehicle to
`
`a desired target destination when traffic jams may be present.” Myr, 2:13-18.
`
`Myr discloses a fleet of travelling vehicles, including mobile units, which
`
`contain an “end-user on-vehicle computer” that receives traffic congestion data
`
`from a central processor unit (CTU). Id., 3:20-28, Fig. 1.

`
`
`
`
`Id., Fig. 1.
`
`Myr’s “traffic congestion data” reflects an abnormal slowdown by
`
`comparing average travel times and normal travel times. The Board confirmed this
`
`interpretation of Myr in an earlier IPR proceeding on Myr, stating that Myr teaches
`
`detecting a “sudden unpredictable change of traffic on a segment as compared to
`
`these regular times,” consistent with the claims of the ’147 patent. Ex. 1010, 15.

`
`
`Current travel times, “which reflect and unpredictable changes to traffic
`
`conditions,” are “periodically broadcast by the CTU … to end-users where they are
`
`entered into the databases of the on-vehicle computers.” Myr, 3:14-19. Upon
`
`“receiving a request from a driver” for navigation to a destination, “the end-user
`
`on-vehicle computer applies an optimization procedure for computing an optimal
`
`route” based on current travel times for individual sections of roads.” Id., 3:20-28.
`
`Myr’s CTU receives GPS data from a plurality of on-vehicle computers and
`
`stores this data in “a database containing travel times for all sections of roads.” Id.,
`
`2:65-3:9. These sections are the segments. Michalson, [0066]-[0071]. Myr’s CTU
`
`assigns each segment a determined “travel time.” Myr, 2:65-3:9.
`
`Myr’s navigation information is updated based on current travel times for the
`
`segments. Id., 6:44-55. Figure 6 below shows that “the route-planning algorithm
`
`calculates the optimal route … [by] requesting travel times for various sections
`
`from the travel time managing algorithm in Unit 9 … , and using the returned
`
`section travel times for further processing.” Id., 6:44-55.

`
`
`
`Id., Fig. 6. The “further processing” relates to “updated information on traffic
`
`bottle neck situations (i.e., … current time and travel times of the latest n
`
`vehicles”) received from the CTU. Id., 3:3-6. The IMU “receive[s] an updated
`
`route reflecting the real time traffic situation,” and the “information will also be
`
`updated by visual and audio instruction.” Id., 4:51-57; Michalson, [0072]-[0073].
`
`Claim 1[f]
`g.
`Myr teaches at least one second radio-frequency transceiver and an
`
`associated at least one second antenna of the wireless communications network
`
`to which the second radio-frequency transceiver is coupled. Myr, 2:65-67, Fig. 4.

`
`
`Myr’s CTU communicates with the mobile units via wireless RF
`
`transmission. Id., Fig. 4, 2:65-67. Myr’s CTU “maintains the database containing
`
`travel times for all sections of roads at a particular time of the day” and “[a]fter
`
`processing the information, CTU sends to the CMUs updated information on
`
`traffic bottleneck situations (i.e. road ID, current time, and travel times of the latest
`
`n vehicles).” Id., 3:3-9. Because Myr’s CTU “broadcasts the uploaded traffic data
`
`collected from a number of sample vehicles via [a] Multicast Broadcasting
`
`System,” a POSA would have understood Myr’s CTU includes a second radio-
`
`frequency transceiver and second antenna to broadcast on the wireless
`
`communications network. Id., 1:8-10; Michalson, [0074]-[0076]. A POSA would
`
`have understood the CTU contains the appropriate hardware for communication,
`
`including a radio-frequency transceiver and antenna. Id.
`
`Claim 1[g]
`h.
`Myr in view of Yiu teaches a second processor (Myr’s CTU) coupled to the
`
`at least one second radio-frequency transceiver (Myr’s CTU RF transmitter and
`
`receiver) programmed to acquire the information indicative of a location of the
`
`wireless mobile communications device, wherein the second processor selectively
`
`acquires the information indicative of a location of the wireless mobile
`
`communications device dependent on the setting of preference flags.

`
`
`i. Myr discloses “a second processor …
`programmed to acquire the information
`indicative of the location of the wireless device”
`Myr’s CTU provides a computer (second processor) programmed to receive
`
`location information from mobile units. Myr, 5:18-24. Myr’s CTU “is configured
`
`to receive GPS data from a fleet” of mobile units and “processes the information
`
`and passes it along to be multicasted to groups of client vehicles.” Id.
`
`Id., Fig. 1.

`
`
`The “GPS data” in Fig. 1 transmitted to the CTU teaches information
`
`indicative of the location of the wireless device and the CTU is the second
`
`processor programmed to acquire the information. Although Fig. 1 of Myr shows
`
`GPS data transmitted only from “sample vehicles,” Myr is clear that client vehicles
`
`also serve as “sample vehicles” and transmit location data to the CMU, stating that
`
`“sample vehicles … can be both clients and serve also as antennas or tentacles for
`
`collecting real time data on traffic situations” “by permanent monitoring of GPS
`
`signals.” Myr, 2:54-59-62; Michalson, [0077]-[0080].
`
`ii. Myr in view of Yiu discloses “selectively
`acquir[ing] the information indicative of a
`location of the wireless mobile communications
`device dependent on the setting of preference
`flags”
`Myr does not expressly disclose setting preference flags but does disclose
`
`providing “various conventional security-related applications such as vehicle
`
`monitoring, warning and alarm systems without RF transmitters, as long as the
`
`vehicle modem is on stand-by.” Myr, 16:9-12. Based on Myr’s monitoring
`
`applications for the mobile units, it would have been obvious to a POSA, in view
`
`of Yiu, to improve Myr to enable user privacy for location sharing, such as
`
`monitoring a vehicle’s location, by incorporating Yiu’s privacy parameter
`
`permissions. Michalson, [0081]-[0082].

`
`
`Yiu discloses enabling the user to set “privacy parameter permissions,”
`
`corresponding to the preference flags. Yiu, 5:24-38. Yiu’s “privacy parameter
`
`permissions” provide a marker used by a second processor in processing or
`
`interpreting information regarding user preferences. Id., 5:24-38.
`
`Yiu discloses “determin[ing] when private information is needed or
`
`requested by another network entity” and “enabling the wireless device to present a
`
`user interface which allows a user of the wireless device to dynamically control the
`
`release of the private information,” such as the information needed for Myr’s
`
`mobile unit to determine and transmit location information. Id., Abstract, 5:11-46.
`
`Yiu discloses a “privacy negotiation GUI” that allows a user to set “privacy
`
`parameter permissions” (blue). Id., 5:24-38.

`Preference flags
`
`
`
`Id., Fig. 2.
`
`Yiu presents to a user “a list of selectable items (‘yes’, ‘no’, ‘always,’
`
`‘never’) from which the user can select to dynamically specify privacy parameter
`
`permissions.” Id., 5:26-29, Fig. 2. A POSA would have understood Yiu’s user
`
`privacy permissions correspond to the preference flags because they are two or
`
`more flags to control access to tracking of the user. Michalson, [0081]-[0086]. The

`
`user configures the setting of these permissions to selectively choose when to share
`
`
`
`
`location information with remote servers. Id.
`
`The claim requires that the second processor selectively acquire
`
`information indicative of a location of the wireless mobile communications
`
`device dependent on the setting of preference flags. In the proposed combination
`
`Myr’s CTU (second processor) receives the location of the mobile unit
`
`(information indicative of a location of the mobile communication device) based
`
`on the setting of Yiu’s privacy parameter permissions (preference flags) to “yes,”
`
`“no,” “always,” or “never.”
`
`iii.
`
`It would have been obvious to a POSA to
`combine the preference flags of Yiu with Myr
`A POSA would have found it obvious to combine Myr’s mobile
`
`communication system, configured for the CTU to determine and transmit the
`
`location of a mobile unit, with the setting of Yiu’s privacy permissions (preference
`
`flags) to allow or prohibit location sharing based on user preferences. Yiu, 5:11-46,
`
`Fig. 2; Michalson, [0088]-[0089].
`
`To enable user privacy and monitoring of Myr’s mobile unit’s location, it
`
`would have been obvious to a POSA to allow a user to set particular location-
`
`sharing preferences on the mobile device, by implementing Yiu’s preference flags,
`
`to prevent the CTU from determining a location of the mobile device at any time.

`Myr, 2:59-61 (“data collection is performed by permanent monitoring of GPS

`
`private, and many users wish to selectively share such private information. Yiu,
`
`1:21-28. The privacy parameter permissions of Yiu, displayed to a user via the user
`
`interface, would provide for a simple, u
