`
`INTRODUCTION
`Apple Inc. (“Petitioner” or “Apple”) submits this Reply to Patent Owner’s
`
`Response (“POR”) to the Petition for Inter Partes Review (“IPR”) of U.S. Patent
`
`No. 10,470,695 (“the ’695 patent”) filed by Masimo Corporation (“Patent Owner”
`
`or “Masimo”). As demonstrated below, the POR fails to rebut the positions
`
`advanced in the Petition. Apple therefore respectfully submits that the Board
`
`should find claims 6, 14, and 211 (“the Challenged Claims”) of the ’695 patent
`
`unpatentable.
`
`For example, Patent Owner attempts to draw a bright line between pulse
`
`oximeters used in body locations having what it terms “thick” tissue (e.g., “the
`
`wrist”), and those used in locations having “thin” tissue (e.g., the “nostril”). See,
`
`e.g., POR, 16-20. The POR characterizes the pulse oximeter described in Chin as a
`
`“thin tissue device” that is so vastly different from “thick tissue” pulse oximeters
`
`(e.g., those described in Sarantos and Ackermans) that Chin’s teachings are
`
`inapplicable to such devices. See id., 19-20; see also APPLE-1022, 23:2-7. But
`
`
`1 The Petition originally challenged claims 1-6, 8, 9, 11-19, and 21-30 of the ’695
`
`patent. Patent Owner subsequently disclaimed claims 1-5, 8, 9, 11-13, 15-19 and
`
`22-30, leaving claims 6, 14, and 21 as the only remaining challenged claims. See
`
`Ex. 2004.
`
`1
`
`
`
`
`Patent Owner provides no evidentiary support for this alleged dichotomy besides
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`the uncorroborated testimony of its own expert, and ignores Chin’s explicit
`
`disclosure that its sensor “could attach to any body part,” as opposed to only those
`
`having “thin tissue.” See id., 16-20; APPLE-1006, 5:55-56.2 Several arguments in
`
`the POR are based on this faulty “thick” / “thin” dichotomy. As explained below,
`
`these arguments fail.
`
`Patent Owner also relies on the results of an “experiment” by Dr. Madisetti
`
`that involved modifying a Masimo pulse oximetry sensor to include a diffuser, and
`
`measuring the amount of reflected light detected by the sensor when performing a
`
`simulated measurement of a tissue analog. See, e.g., POR, 20 (citing EX2001,
`
`[58]-[59]). But these results are irrelevant to the present proceeding, because the
`
`Masimo pulse oximeter used in these experiments includes a single photodetector,
`
`rather than the plurality of photodetectors included in each of the prior art
`
`combination and required by the claims of the ’695 patent. See EX2001,
`
`Appendix, p. 1; Petition, 11-17, 71-75; APPLE-1001, claim 1 (reciting “a plurality
`
`of detectors”). The device used in Dr. Madisetti’s experiment is thus drastically
`
`different from the devices described in the proposed prior art combinations, and
`
`
`2 All emphasis added unless indicated otherwise.
`
`2
`
`
`
`
`therefore, as explained below, the results of the experiment are not indicative of the
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`performance of the combined prior art devices.
`
`For these and other reasons described herein, Apple respectfully submits that
`
`the Board should find claims 6, 14, and 21 (“the Challenged Claims”) of the ’695
`
`patent unpatentable.
`
`II. CLAIMS 6, 14, AND 21 ARE UNPATENTABLE
`As explained in the Petition, claims 6, 14, and 21 of the ’695 patent are
`
`rendered obvious by the combination of Sarantos, Mendelson-1991, and Chin
`
`(Ground 1D, see Petition, 60-64), and by the combination of Ackermans and Chin
`
`(Ground 2C, see Petition, 102-106).3 The POR presents several arguments with
`
`respect to these Grounds. As explained in the sections below, these arguments fail.
`
`A.
`
`Patent Owner’s invented distinction between “thick tissue” and
`“thin tissue” devices is not supported by the evidence of record
`Patent Owner attempts to draw a bright line between pulse oximeters used in
`
`body locations having what it terms “thick” tissue (e.g., “the wrist”), and those
`
`used in locations having “thin” tissue (e.g., the “nostril”). See, e.g., POR, 16-20.
`
`The POR characterizes the pulse oximeter described in Chin as a “thin tissue
`
`device” that is so vastly different from “thick tissue” pulse oximeters (e.g., those
`
`
`3 Petition Grounds 1A-1C and 2A-2B are directed solely to claims disclaimed by
`
`Patent Owner. See Ex. 2004.
`
`3
`
`
`
`
`described in Sarantos and Ackermans) that Chin’s teachings are inapplicable to
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`such devices. See id., 19-20; see also APPLE-1022, 23:2-7. This argument lacks
`
`support in—and is in fact contradicted by—the evidence of record.
`
`Patent Owner provides no evidentiary support—besides uncorroborated
`
`testimony from its expert—for this alleged dichotomy between “thin tissue” and
`
`“thick tissue” pulse oximeters. See POR, 16-20 (citing EX2001, [52]-[56]).
`
`Similarly, it relies solely on uncorroborated expert testimony to support its
`
`conclusion that pulse oximetry techniques described with respect to one tissue
`
`site—such as those described in Chin—are inapplicable to devices operating at a
`
`different tissue site—such as the wrist-worn devices described in Sarantos and
`
`Ackermans. See POR, 16-20 (citing EX2001, [52]-[56]). It is well-settled that
`
`uncorroborated expert testimony, such as Dr. Madisetti’s testimony relied on by
`
`Patent Owner, is insufficient to support arguments regarding obviousness. See TQ
`
`Delta v. Cisco Systems, 942 F. 3d 1352, 1358-1363 (Fed. Cir. 2019) (“This court's
`
`opinions have repeatedly recognized that conclusory expert testimony is
`
`4
`
`
`
`
`inadequate to support an obviousness determination on substantial evidence
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`review”).4
`
`Although the POR includes a handful of citations to Chin, Sarantos, and
`
`Ackermans in its “thick tissue” / “thin tissue” argument, the cited disclosure does
`
`not support Patent Owner’s alleged distinction between “thin tissue” and “thick
`
`tissue” devices. See POR, 16-20 (citing APPLE-1006, 1:14-21, 2:39-62, 7:13-41,
`
`8:21-29, FIGS. 5C-5E, 7B; APPLE-1014, 7:12-16; APPLE-1015, 15:43-45). In
`
`fact, neither Sarantos, nor Ackermans, nor Chin describes its pulse oximeter as
`
`applicable to only “thick” or “thin” tissue, and none of these references use the
`
`terms “thick” or “thin” when describing tissue measurement sites. See APPLE-
`
`1006, APPLE-1014, APPLE-1016.
`
`No evidence of record supports Patent Owner’s alleged distinction. In fact,
`
`Chin specifically states that its sensor “could attach to any body part,” thereby
`
`contradicting Patent Owner’s classification of Chin as directed only to “thin tissue”
`
`devices. APPLE-1006, 5:55-56. In addition, it was well-known that reflectance
`
`
`4 Patent Owner and its expert fail to even provide information on how to categorize
`
`a particular tissue site as “thick” or “thin.” See POR, 16-20; see also APPLE-
`
`1022, 19:15-20:17, 21:18-22:16 (Dr. Madisetti refusing to explain his definition of
`
`“thin” tissue).
`
`5
`
`
`
`
`pulse oximeters, such as those described in Sarantos and Ackermans, “can be used
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`to measure arterial oxygen saturation at virtually any place on the human body.”
`
`See, e.g., APPLE-1021, 88; see also 91 (“Reflectance probes can be placed on
`
`virtually any place on the body where we can expect light reflection due to
`
`tissue”). This flexibility in the placement location of reflectance pulse oximeters
`
`runs counter to the alleged distinction between “thick” and “thin” pulse oximeters
`
`upon which Patent Owner bases many of its arguments. See, e.g., POR, 16-20.
`
`Patent Owner’s distinction between “thick tissue” and “thin tissue” pulse
`
`oximeters is thus unsupported by the evidence of record. Accordingly, the many
`
`arguments in the POR that rely on this theory must fail.
`
`B. Dr. Madisetti’s experimental results are not indicative of the
`performance of devices with multiple photodetectors
`Patent Owner also alleges that, contrary to Chin’s explicit disclosure, adding
`
`diffuser would “have significant detrimental consequences to the performance of a
`
`pulse oximeter.” POR, 21; contra APPLE-1006, 8:24-28 (“optical diffuser 180…
`
`causes a further spreading or mixing of light and may enhance the amount of tissue
`
`penetrated in some instances”). To support this argument, the POR cites results of
`
`an experiment in which Dr. Madisetti selected and placed two commercially-
`
`available diffusers over the emitter of a Masimo pulse oximetry sensor, and
`
`measured the amount of reflected light detected by the sensor when performing a
`
`simulated measurement of a tissue analog. See, e.g., POR, 20 (citing EX2001,
`
`6
`
`
`
`
`[58]-[59]). Beyond showing the feasibility and predictability of the proposed prior
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`art combinations (by combining an optical diffuser with a wrist-worn reflectance
`
`pulse oximeter), Dr. Madisetti’s experiment is irrelevant to the present proceeding,
`
`because the Masimo pulse oximeter used in these experiments includes a single
`
`photodetector, as shown in the following excerpt from Dr. Madisetti’s declaration:
`
`
`
`Single-detector device used in Dr. Madisetti’s experiment.
`EX2001, Appendix p 1 (annotations in original)
`
`Conversely, the devices described in Sarantos and Ackermans, which form
`
`the basis of the two proposed combinations, both include a plurality of
`
`photodetectors, as required by the claims of the ’695 patent. See Petition, 11-17,
`
`71-75; APPLE-1001, claim 1 (reciting “a plurality of detectors”). The following
`
`annotated figures show these configurations with the multiple photodetectors
`
`annotated in green:

`
`APPLE-1014 (Sarantos),
`Detail of FIG. 15 (annotated)
`
`APPLE-1016 (Ackermans),
`Detail of FIG. 2 (annotated)
`
`
`
`See also APPLE-1015, 2 (FIG. 1 depicts a device with multiple photodetectors
`
`arranged around a central LED).
`
`Devices with multiple detectors will detect additional reflected light that will
`
`not be detected by a single detector (i.e., light that strikes the area of the device
`
`covered by the additional detector). See, e.g., APPLE-1014, 14:46-55 (explaining
`
`that using multiple photodetectors arrange around the light source can lead to more
`
`light being detected and thus “increase the signal to ambient noise ratio” of the
`
`device); APPLE-1015, 2 (“The major feature of the optical layout design is the
`
`multiple photodiode array, which….maximizes the amount of backscattered light
`
`that is detected by the sensor”). Thus, the single-detector device used in Dr.
`
`Madisetti’s experiment is fundamentally different from the devices described in the
`
`Sarantos and Ackermans combinations, and therefore the results of the experiment
`
`8
`
`
`
`
`are not indicative of the performance of the combined prior art devices of Sarantos
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`and Ackermans. Accordingly, the many arguments in the POR that rely on this
`
`theory must fail.
`
`C. Ground 1D: Claims 6, 14, and 21 are obvious over Sarantos in
`view of Mendelson-1991 and Chin
`As explained in the Petition, the Sarantos-Mendelson-1991-Chin
`
`combination renders claim 6, 14, and 21 obvious. See Petition, 60-64. The POR
`
`presents various arguments with respect to this Ground. As explained in the
`
`sections below, these arguments fail.
`
`1.
`
`A POSITA would have been motivated to add Chin’s
`diffuser to the combined device of Sarantos and Mendelson-
`1991
`As explained in the Petition:
`
`[A] POSITA would have been motivated to
`incorporate Chin’s diffuser into the pulse oximeter of
`Sarantos and Mendelson because the diffuser will cause
`the light “to pass through more tissue, and thus more
`blood,” resulting in a stronger reflected signal at the
`detectors, which “allows it to be more easily processed by
`the oximeter electronics and software” to determine the
`measured physiological parameters.
`
`Petition, 62-63 (quoting APPLE-1006, 2:4-7, 9:64-10:7) (citing APPLE-
`
`1006, 8:25-29; APPLE-1003, [99]). Patent Owner argues that the “Sarantos
`
`9
`
`
`
`
`discloses a wrist-worn sensor applied to thick tissue, which does not suffer the
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`same thin tissue problem that Chin attempts to solve.” POR, 22, 23. But, as
`
`described above (see Section II.A, supra), Patent Owner’s distinction between
`
`“thick tissue” and “thin tissue” devices has no basis in Chin or Sarantos—neither
`
`reference describes such a distinction—or indeed in any of the evidence of record.
`
`In fact, Chin specifically states that its sensor “could attach to any body part,”
`
`thereby contradicting Patent Owner’s classification of Chin as only being
`
`concerned with a “thin tissue problem.” APPLE-1006, 5:55-56.
`
`Patent Owner also argues that “the addition of a diffuser in a reflectance
`
`sensor significantly reduces the amount of light reaching the detector,” and relies
`
`only on the results of Dr. Madisetti’s single-detector experiment for support. See
`
`POR, 22-24. But, as explained above (see Section II.B, supra), the results of Dr.
`
`Madisetti’s single-detector experiment are not indicative of the performance of
`
`devices with multiple photodetectors.
`
`Thus, for at least these reasons, these arguments fail.
`
`2.
`
`A POSITA would have had a reasonable expectation of
`success when performing the proposed modification
`The Petition states that “because a POSITA would be implementing the
`
`diffuser in a known way (specifically the way described in Chin), a POSITA would
`
`have had a reasonable expectation of success in integrating the diffuser of Chin
`
`into the pulse oximetry sensor of the Sarantos-Mendelson-1991 combination.”
`
`10
`
`
`
`
`Petition, 62 (citing APPLE-1003, [98]; APPLE-1006, 8:20-28). Patent Owner
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`argues that a POSITA would have had no reasonable expectation of success in
`
`adding Chin’s diffuser to the combined device of Sarantos-Mendelson-1991
`
`because it alleges, again relying on the results of Dr. Madisetti’s single-detector
`
`experiment, that the amount of light reaching the detectors would be reduced by
`
`the addition of the diffuser. POR, 24-25. But, as explained above (see Section
`
`II.B, supra), the results of Dr. Madisetti’s single-detector experiment are not
`
`indicative of the performance of devices with multiple photodetectors, and
`
`therefore fail to support Patent Owner’s argument.
`
`Petitioner’s argument regarding reasonable expectation of success,
`
`conversely, is supported by the explicit disclosure of Chin, which, contrary to
`
`Patent Owner’s characterizations, is explicitly directed to sensors attached to “any
`
`body part.” See APPLE-1006, 5:55-56; Petition, 62 (citing APPLE-1003, [98];
`
`APPLE-1006, 8:20-28).
`
`Accordingly, Patent Owner’s arguments fail.
`
`3.
`
`Patent Owner's arguments rely on mischaracterizations of
`the prior art that ignore explicit disclosures in the
`references
`Patent Owner repeatedly mischaracterizes the prior art references in self-
`
`serving ways to attempt to undermine the combinations described in the Petition.
`
`For example, as previously discussed (see Section II.A, supra), Patent Owner
`
`11
`
`
`
`
`characterizes Chin as limited to a “nostril-based” sensor even though the reference
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`explicit states that its sensor “could attach to any body part.” APPLE-1006, 5:55-
`
`56.
`
`In addition, Patent Owner characterizes Sarantos as limited to configurations
`
`where the photodetectors are spaced “1 mm to 4 mm” from the central emitter.
`
`See, e.g., POR, 28, 30. But Sarantos specifically states that “implementations
`
`discussed herein may be used in products that achieve closer or farther spacing
`
`from the light source center, such as spacing closer than 1 mm or farther than 4
`
`mm.” APPLE-1014, 18:66-19:2. Further, Patent Owner’s arguments regarding
`
`these dimensions assume, without support, that the addition of Chin’s diffuser
`
`would spread the light from Sarantos’ emitter to an extent that the pattern of light
`
`reaching the photodetectors would be vastly changed, thus disrupting the operation
`
`of the device. POR, 29-32. Nothing in the references or in the description of the
`
`combination in the Petition suggests that the effect of Chin’s diffuser would be so
`
`drastic. In fact, even a slight spreading of the emitted light would still “cause [the
`
`light] to pass through more tissue, and thus more blood” thereby leading to
`
`improved performance, as taught by Chin. See APPLE-1006, 2:4-9, 8:25-29.
`
`Thus, Patent Owner’s arguments fail.
`
`12
`
`
`
`
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`D. Ground 2C: Claims 6, 14, 21 are obvious over Ackermans in view
`of Chin
`As explained in the Petition, the Ackermans-Chin combination renders
`
`claims 6, 14, and 21 obvious. See Petition, 102-106. The POR presents various
`
`arguments with respect to this Ground, many of which are nearly identical to those
`
`presented with respect to Ground 1D. As explained in the sections below, these
`
`arguments fail.
`
`1.
`
`A POSITA would have been motivated to add Chin’s
`diffuser to Ackermans’ device
`As explained in the Petition:
`
`[A] POSITA would have been motivated to
`incorporate Chin’s diffuser into the pulse oximeter of
`Ackermans because the diffuser will cause the light “to
`pass through more tissue, and thus more blood,” resulting
`in a stronger reflected signal at the detectors, which
`“allows it to be more easily processed by the oximeter
`electronics and software” to determine the measured
`physiological parameters.
`
`Petition, 102-103 (quoting APPLE-1006, 2:4-7, 9:64-10:7) (citing APPLE-
`
`1006, 8:25-29; APPLE-1003, [99]). Patent Owner argues that the “Ackermans
`
`discloses a wrist-worn sensor applied to thick tissue,” and “a POSITA having
`
`Ackermans’ device would have no reason to look to Chin for Chin’s solutions to
`
`its thin tissue problem.” POR, 34. But, as described above (see Section II.A,
`
`13
`
`
`
`
`supra), Patent Owner’s distinction between “thick tissue” and “thin tissue” devices
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`has no basis in Chin or Ackermans—neither reference describes such a
`
`distinction—or indeed in any of the evidence of record. In fact, Chin specifically
`
`states that its sensor “could attach to any body part,” thereby contradicting Patent
`
`Owner’s classification of Chin as only being concerned with a “thin tissue
`
`problem.” APPLE-1006, 5:55-56.
`
`Patent Owner also argues that “the addition of a diffuser in a reflectance
`
`sensor significantly reduces the amount of light reaching the detector,” and relies
`
`only on the results of Dr. Madisetti’s single-detector experiment for support. See
`
`POR, 35. But, as explained above (see Section II.B, supra), the results of Dr.
`
`Madisetti’s single-detector experiment are not indicative of the performance of
`
`devices with multiple photodetectors.
`
`Thus, for at least these reasons, these arguments fail.
`
`2.
`
`A POSITA would have had a reasonable expectation of
`success when performing the proposed modification
`The Petition states that “because a POSITA would be implementing the
`
`diffuser in a known way (specifically the way described in Chin), a POSITA would
`
`have had a reasonable expectation of success in integrating the diffuser of Chin
`
`into the pulse oximetry sensor of the Sarantos-Mendelson-1991 combination.”
`
`Petition, 104 (citing APPLE-1003, [162]; APPLE-1006, 8:20-28). Patent Owner
`
`argues that a POSITA would have had no reasonable expectation of success in
`
`14
`
`
`
`
`adding Chin’s diffuser to Ackerman’s device because it alleges, again relying on
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`the results of Dr. Madisetti’s single-detector experiment, that the amount of light
`
`reaching the detectors would be reduced by the addition of the diffuser. POR, 36-
`
`37. But, as explained above (see Section II.B, supra), the results of Dr. Madisetti’s
`
`single-detector experiment are not indicative of the performance of devices with
`
`multiple photodetectors, and therefore fail to support Patent Owner’s argument.
`
`Petitioner’s argument regarding reasonable expectation of success is
`
`supported by the explicit disclosure of Chin, which, contrary to Patent Owner’s
`
`characterizations, is directed to sensors attached to “any body part.” See APPLE-
`
`1006, 5:55-56. Thus, as described in the Petition, the diffuser from Chin’s pulse
`
`oximeter could be integrated with the pulse oximeter of Ackermans in the manner
`
`described in Chin. See Petition, 104.
`
`Accordingly, Patent Owner’s arguments fail.
`
`3.
`
`Patent Owner’s arguments rely on mischaracterizations of
`the prior art that ignore explicit disclosures in the
`references
`Patent Owner repeatedly mischaracterizes the prior art references in self-
`
`serving ways to attempt to undermine the combinations described in the Petition.
`
`For example, as previously discussed (see Section II.A, supra), Patent Owner
`
`characterizes Chin as limited to a “nostril-based” sensor even though the reference
`
`explicit states that its sensor “could attach to any body part.” APPLE-1006, 5:55-
`
`15
`
`
`
`
`56. Further, Patent Owner’s arguments assume, without support, that the addition
`
`Case No. IPR2020-01722
`Attorney Docket: 50095-0004IP1
`
`of Chin’s diffuser would spread the light from Ackermans’ emitter to an extent that
`
`the pattern of light reaching the photodetectors would be vastly changed, thus
`
`disrupting the operation of the device. POR, 40-42. Nothing in the references or
`
`in the Petition’s description of the combination suggests that the effect of Chin’s
`
`diffuser would be so drastic. In fact, even a slight spreading of the emitted light
`
`would still “cause [the light] to pass through more tissue, and thus more blood”
`
`thereby leading to improved performance, as taught by Chin. See APPLE-1006,
`
`2:4-9, 8:25-29.
`
`Thus, Patent Owner’s arguments fail.
`
`III. CONCLUSION
`Petitioner respectfully submits that the Board should find the Challenged
`
`Claims unpatentable.
