Heading: “type of telemetry”

Text: The Board found that Torgerson ’756 discloses a telemetry unit that listens for a first type of telemetry from an Case: 19-1584 Document: 71 Page: 6 Filed: 05/18/2020 6 BOSTON SCIENTIFIC v. NEVRO CORP. external physician programmer and patient programmer. The Board further found that “Torgerson ’756 covers the use of a second type of telemetry for battery charging operations.” J.A. 39 (emphasis in original). Boston Scientific argues that the latter finding is not supported by substantial evidence. It contends that Torgerson ’756 discloses only one type of telemetry—inductive telemetry—and therefore Torgerson ’756 does not disclose a second type of telemetry. Torgerson ’756 discloses a telemetry unit that listens for a first type of telemetry. Nevro argues that Torgerson ’756’s recharge module, which uses “other communication techniques” to communicate with an external charger, uses a second type of telemetry. The recharge module comprises a recharge regulation control unit that “communicates with [an] external component via telemetry unit 305.” J.A. 1129 at 7:41–45; J.A. 1130 at 9:46–47. Torgerson ’756 further discloses the implementation of “other communication techniques” where “recharge regulation control unit 525 communicates with the external component by modulating the load on the recharge coil[, which] can then be sensed in the circuitry driving the source coil of the external component.” J.A. 1130 at 9:48–53. There is nothing in the ’241 patent specification that precludes this communication technique from constituting a second “type of telemetry” merely because it is not a different type of energy transfer modality. Indeed, Boston Scientific’s expert, Dr. Ronald Berger testified that “it is the modulation of the electromagnetic wave that makes it a telemetry link.” J.A. 1416 ¶ 33. Dr. Berger also testified that “it is possible that the Torgerson ’756 may use two types of telemetry . . . for the internal device to communicate outward to the external device.” J.A. 1317 at 140:17–20. We therefore hold that substantial evidence supports the Board’s finding that the recharge regulation control unit employs a second type of telemetry to communicate the change in load to the external component. J.A. 38. Case: 19-1584 Document: 71 Page: 7 Filed: 05/18/2020 BOSTON SCIENTIFIC v. NEVRO CORP. 7
