`Apple v. Masimo
`
`I.
`
`INTRODUCTION
`
`Petitioner’s proposed combinations all suffer from the same underlying
`
`flaws. Petitioner’s combinations rely primarily on Aizawa and Ohsaki, but
`
`Petitioner ignores critical differences between these references that make them
`
`incompatible.
`
`First, Ohsaki discloses a sensor with a convex board that must be used on the
`
`back side (i.e., watch side) of the wrist to provide its asserted benefit of improved
`
`adhesion, taking advantage of the user’s bone structure. In contrast, Aizawa
`
`expressly states that its sensor is used on the palm side of the wrist, where it is
`
`positioned over the user’s artery. Petitioner argues a POSITA would have been
`
`motivated to combine Ohsaki’s convex board with Aizawa’s sensor so as “to
`
`improve adhesion between the user’s wrist and the sensor.” Pet. 22-23. But
`
`Ohsaki discloses its board “has a tendency to slip off” the palm side of the wrist.
`
`Ex. 1009 ¶[0023]. Accordingly, a POSITA seeking to improve Aizawa’s palm-
`
`side sensor would not have been motivated to add Ohsaki’s convex board,
`
`designed for the back side of the wrist. Rather, a POSITA would have
`
`affirmatively avoided making that change.
`
`Second, Ohsaki’s sensor uses a longitudinal structure in a specific
`
`orientation between bones on the back side of the wrist to reduce sensor slippage
`
`and motion. Aizawa, however, discloses a circular sensor which provides more
`
`-1-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`consistent measurements when measuring signals from the arteries on the palm
`
`side of the wrist. Transforming Ohaski’s longitudinal structure into a circular
`
`shape to fit Aizawa’s sensor would eliminate Ohsaki’s benefit of reduced slippage
`
`and movement. Conversely, changing Aizawa’s circular sensor to accommodate
`
`Ohsaki’s longitudinal structure would result in less consistent measurements. The
`
`combination of Aizawa and Ohsaki would either disrupt Aizawa’s circular
`
`symmetry, Ohsaki’s longitudinal structure, or both. Petitioner attempts to combine
`
`references that are simply incompatible.
`
`Third, Petitioner’s combination detrimentally places a convex-shaped cover
`
`over Aizawa’s peripherally located detectors. A POSITA would have believed
`
`that such a cover would undesirably direct light away from the peripheral
`
`detectors and toward the sensor’s center, thereby reducing light collection and
`
`signal strength. A POSITA would not have been motivated to decrease signal
`
`strength in the manner resulting from Petitioner’s combination.
`
`In short, Ohsaki and Aizawa employ different sensor structures (rectangular
`
`versus circular) for different measurement locations (back side versus palm side of
`
`the wrist), using different sensor surface shapes (convex versus flat) that are
`
`tailored to those specific measurement locations. Petitioner does not even
`
`acknowledge these differences, much less show a POSITA would have been
`
`-2-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`motivated
`
`to combine
`
`these references and reasonably expected such a
`
`combination to be successful.
`
`
`
`For at least these reasons, Petitioner fails to demonstrate the asserted
`
`references render the claims obvious. The Board should affirm the patentability of
`
`all ’564 Patent claims.
`
`II. MASIMO’S PIONEERING TECHNOLOGY
`
`Masimo is a global medical device technology company that develops and
`
`manufactures innovative patient monitoring technologies, medical devices, and a
`
`wide array of sensors. Inventor Joe Kiani founded Masimo in 1989 as a garage
`
`start-up that revolutionized noninvasive patient monitoring. Today, Masimo is
`
`publicly traded company that employs over 6,300 people worldwide, with annual
`
`revenues of over $1.1 billion. A host of manufacturers use Masimo’s technology,
`
`including Philips, Atom, Mindray North America, GE Medical, Spacelabs, and
`
`Zoll.
`
`A. The ’564 Patent Claims
`
`Masimo’s U.S. Patent No. 10,624,564 (“’564 Patent”) discloses and claims
`
`an optical physiological measurement device that uses an innovative design to
`
`improve detection efficiency. Masimo’s claimed measurement device uses one or
`
`more emitters, multiple detectors, and a cover with a protrusion that works with a
`
`wall surrounding the detectors, enhancing sensor and device effectiveness. The
`
`-3-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`protrusion thins out the measurement site so the measured tissue attenuates less
`
`light. Ex. 1001 7:56-61. The protrusion further increases the area from which
`
`attenuated light can be measured. Id. 7:61-63. The wall connecting the cover and
`
`substrate also maximizes the amount of light that impinges on the detectors, further
`
`increasing the signal strength. Id. 36:45-51. The multiple detectors allow for an
`
`averaging of measurements that can reduce errors due to variations in the path of
`
`light passing through the tissue. Id. 9:28-33; see also id. 3:4-15, 4:25-35. The
`
`inventors discovered this innovative combination of features work together to
`
`provide greater noise cancellation and an order of magnitude increase in signal
`
`strength. Id. 9:28-33, 20:25-42; see also id. 3:4-15, 4:27-35; Ex. 2004 ¶27.
`
`B.
`
`Introduction To Independent Claims
`
`The ’564 Patent has one independent claim: claim 1.1 Claim 1 is directed to
`
`a physiological measurement device including, among other things: (1) one or
`
`more emitters configured to emit light into tissue of a user, (2) at least four
`
`detectors arranged on a substrate, (3) a cover comprising a protruding convex
`
`surface, and (4) a wall that surrounds the detectors and connects to the substrate
`
`and the cover. See claim 1. Claim 1 reads:
`
`
`1 Appendix A reproduces the challenged claims with bracketed labels for
`
`convenience.
`
`-4-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`1. A user-worn physiological measurement device comprising:
`
`one or more emitters configured to emit light into tissue of a
`
`user;
`
`at least four detectors arranged on a substrate;
`
`a cover comprising a protruding convex surface, wherein the
`
`protruding convex surface extends over all of the at least four
`
`detectors arranged on the substrate, wherein at least a portion of the
`
`protruding convex surface is rigid;
`
`one or more processors configured to:
`
`receive one or more signals from at least one of the at
`
`least four detectors, the one or more signals responsive to at
`
`least a physiological parameter of the user; and
`
`process
`
`the one or more signals
`
`to determine
`
`measurements of the physiological parameter;
`
`a network interface configured to communicate with a mobile
`
`phone;
`
`a touch-screen display configured to provide a user interface,
`
`wherein:
`
`-5-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`the user interface is configured to display indicia
`
`responsive to the measurements of the physiological parameter,
`
`and
`
`an orientation of the user interface is configurable
`
`responsive to a user input;
`
`a wall that surrounds at least the at least four detectors,
`
`wherein the wall operably connects to the substrate and the cover;
`
`a storage device configured to at least temporarily store at least
`
`the measurements of the physiological parameter; and
`
`a strap configured to position the physiological measurement
`
`device on the user.2
`
`C. The ’564 Patent Prosecution
`
`During prosecution, the Examiner agreed the claimed combination of
`
`features—including multiple detectors in conjunction with a cover comprising a
`
`protrusion—provided a patentable advance unique in the field. Ex. 1002 at 102-
`
`106. Petitioner’s references do not differ significantly from the prior art the
`
`Examiner considered and found does not teach or suggest the claimed invention.
`
`
`2 Emphasis supplied unless otherwise noted.

`Apple v. Masimo
`
`III. THE PETITION’S PROPOSED COMBINATIONS
`
`Petitioner presents six grounds. Pet. 9. Ground 1 combines three references:
`
`Aizawa (Ex. 1006), Ohsaki (Ex. 1009), and Goldsmith (Ex. 1011). Grounds 2-3
`
`challenge dependent claims and combine additional references with Aizawa,
`
`Ohsaki, and Goldsmith. Ground 4 combines four references: Aizawa, Ohsaki,
`
`Goldsmith, and Ali (Ex. 1019). Grounds 5-6 challenge dependent claims and
`
`combine additional references with Aizawa, Ohsaki, Goldsmith, and Ali.
`
`IV. CLAIM CONSTRUCTION
`
`Petitioner identifies no terms for construction. The Board should give the
`
`claim
`
`terms
`
`their ordinary and customary meaning, consistent with
`
`the
`
`specification, as a POSITA would understand them. 37 C.F.R. § 42.100(b);
`
`Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc).
`
`V. LEVEL OF ORDINARY SKILL IN THE ART
`
`Petitioner asserts a POSITA “would have been a person with a working
`
`knowledge of physiological monitoring technologies. The person would have had a
`
`Bachelor of Science degree in an academic discipline emphasizing the design of
`
`electrical, computer, or software technologies, in combination with training or at
`
`least one to two years of related work experience with capture and processing of
`
`data or information, including but not limited to physiological monitoring
`
`technologies.” Pet. 8. Petitioner asserts “[a]dditional education in a relevant field
`
`-7-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`or industry experience may compensate for one of the other aspects of the POSITA
`
`characteristics stated above.” Id.
`
`Masimo notes that Petitioner’s asserted level of skill (1) requires no
`
`coursework, training or experience with optics or optical physiological monitors;
`
`(2) requires no coursework, training or experience in physiology; and (3) focuses
`
`on data processing and not sensor design. For this proceeding, Masimo
`
`nonetheless applies Petitioner’s asserted level of skill. Ex. 2004 ¶¶30-32.
`
`VI. LEGAL STANDARD
`
`A petition based on “obviousness requires a suggestion of all limitations in a
`
`claim.” CFMT, Inc. v. YieldUp Int’l Corp., 349 F.3d 1333, 1342 (Fed. Cir. 2003)
`
`(citing In re Royka, 490 F.2d 981, 985 (C.C.P.A. 1974)). A patent claim is not
`
`obvious unless “a skilled artisan would have been motivated to combine the
`
`teachings of the prior art references to achieve the claimed invention, and that the
`
`skilled artisan would have had a reasonable expectation of success in doing so.”
`
`ActiveVideo Networks, Inc. v. Verizon Commc’ns, Inc., 694 F.3d 1312, 1327 (Fed.
`
`Cir. 2012).
`
`To prevail on any obviousness ground, a petitioner may not simply identify
`
`individual claim components—it must show why a “skilled artisan, with no
`
`knowledge of the claimed invention, would have selected these components for
`
`combination in the manner claimed.” In re Kotzab, 217 F.3d 1365, 1371 (Fed. Cir.
`
`-8-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`2000). The petitioner must support even simple modifications with some
`
`motivation to make the change. See In re Gordon, 733 F.2d 900, 902 (Fed. Cir.
`
`1984).
`
`An appropriate obviousness inquiry cannot involve even a “hint of
`
`hindsight.” Star Sci., Inc. v. R.J. Reynolds Tobacco Co., 655 F.3d 1364, 1375
`
`(Fed. Cir. 2011). A petitioner may not “simply retrace[] the path of the inventor
`
`with hindsight, discount[] the number and complexity of the alternatives, and
`
`conclude[] that the invention ... was obvious.” Ortho-McNeil Pharm., Inc. v.
`
`Mylan Labs., Inc., 520 F.3d 1358, 1364 (Fed. Cir. 2008). Likewise, “[c]are must
`
`be taken to avoid hindsight reconstruction by using the patent in suit as a guide
`
`through the maze of prior art references, combining the right references in the right
`
`way so as to achieve the result of the claims in suit.” In re NTP, Inc., 654 F.3d
`
`1279, 1299 (Fed. Cir. 2011) (internal quotations omitted).
`
`VII. GROUND 1 FAILS TO DEMONSTRATE OBVIOUSNESS
`
`A. Ground 1’s Cited Art And Asserted Combination
`
`Ground 1, like all of Petitioner’s grounds, combines Aizawa and Ohsaki.
`
`These references each disclose different physiological sensor designs, with distinct
`
`shapes, features, and detector-emitter configurations. This section introduces
`
`Petitioner’s proposed combination of Ohsaki and Aizawa and then discusses Dr.
`
`Kenny’s erroneous characterization of Ohsaki.
`
`-9-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`1.
`
`Petitioner’s Combination Of Ohsaki And Aizawa
`
`Ohsaki discloses a pulse rate sensor with a single emitter (e.g., an LED) and
`
`a single detector disposed linearly, side-by-side, under a translucent board. See,
`
`e.g., Ex. 1009 Abstract, Fig. 2, ¶[0019]; Ex. 2004 ¶35.
`
`
`
`Ohsaki (Ex. 1009) Figs. 1 and 2 (annotated, color added)
`
`Ohsaki’s linearly arranged detector and emitter (above) result in a longitudinal
`
`shape and direction that Ohsaki explains is important for to reduce slipping when
`
`placed against the backhand side of the wrist. See Ex. 1009 ¶[0019] (if the
`
`longitudinal direction of Ohsaki’s detecting element 2 “agrees with
`
`the
`
`circumferential direction of the user’s wrist 4, it has a tendency to slip off.
`
`Therefore it is desirable that the detecting element 2 is arranged so that its
`
`-10-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`longitudinal direction agrees with the longitudinal direction of the user’s arm.”).
`
`Ohsaki includes a “dedicated belt” that “fix[es] the detecting element 2 on the
`
`user’s wrist 4 in this way.” Id. ¶[0019]. Ohsaki repeatedly states that its sensor “is
`
`worn on the back side of a user’s wrist corresponding to the back of the user’s
`
`hand.” Ex. 1009 Abstract; see also id. Title, ¶¶ [0008], [0009], [0016], [0024]; Ex.
`
`2004 ¶35.
`
`In contrast, Aizawa discloses a sensor with four periphery-located
`
`photodetectors (22) around a single centrally located LED (21). Ex. 1006 Abstract,
`
`Fig. 1B.; Ex. 2004 ¶¶40-41.

`
`
`
`
`
`Aizawa Fig. 1A (top-down view, color added)
`
`Aizawa uses this specific configuration of multiple detectors arrayed around a
`
`single LED to ensure that at least one detector is near the measurement site, which
`
`Aizawa indicates improves measurement consistency. Ex. 1006 ¶[0027]. Aizawa
`
`detects signals on the palm side of the wrist and explains that as long as “one of the
`
`photodetectors 22 is located near the artery 11,” it is “possible to detect a pulse
`
`wave accurately.” Id. ¶¶[0026]-[0027], Fig. 2. Aizawa includes a flat transparent
`
`plate (6) that improves adhesion between the detector and the wrist, which Aizawa
`
`-12-
`
`
`
`IPR2020-01713 – Patent 10,624,564
`Apple v. Masimo
`
`states improves the detection efficiency. Id. [0030]. Aizawa’s sensor does not use
`
`a lens. Ex. 2004 ¶¶40-41.
`
`Petitioner argues a POSITA would have added Ohsaki’s translucent board,
`
`designed for a linear pulse sensor, to Aizawa’s circular sensor. Pet. 19-23. But
`
`Petitioner never identifies with specificity the resulting structure. Petitioner
`
`asserts: “[a]s shown below, a POSITA would have modified Aizawa’s flat cover
`
`to include a protruding convex surface, similar to Ohsaki’s” (Pet. 22-23):
`
`Petitioner’s Illustration (Pet. 23)
`
`
`
`Petitioner never identifies whether Ohsaki’s longitudinal board is simply placed
`
`over Aizawa, or whether its shape is changed to be circular to match Aizawa’s
`
`shape and detector arrangement. Ex. 2004 ¶¶42-43.
`
`2.
`
`Dr. Kenny’s Erroneous Characterization Of Ohsaki
`
`At his deposition in a related IPR proceeding, Dr. Kenny injected even more
`
`confusion into Petitioner’s combinations. Dr. Kenny testified he did not know the
`
`shape of Ohsaki’s board and that Ohsaki’s board could be “circular or square or

`rectangular.” Ex. 2008 68:21-70:1, 71:7-72:10. Dr. Kenny is incorrect. Ohsaki
`
`illustrates two cross-sectional views of its board that confirm the board is
`
`rectangular (and not circular or square). Id.
`
`Specifically, Ohsaki Figure 2 (below left) illustrates the “long” side of
`
`Ohsaki’s detector element (2) that extends from left to right in Figure 2 and in the
`
`longitudinal direction (up-and-down the arm) on a user’s wrist. Ex. 1009 ¶[0019];
`
`Ex. 2004 ¶¶36-39.

`Ohsaki Ex. 1009 Fig. 2 (left) & Fig. 1 (right) showing different cross-sections
`(color added: Purple: detecting element 2/package 5; Blue: translucent board 8)
`
`
`Figure 2 (above left) shows that the board (8) spans nearly the entire length of the
`
`detecting element’s (2) “long” side. Ohsaki Figure 1 (above right) shows the
`
`“short” side of Ohsaki’s detecting element (2) that extends from left to right in
`
`Figure 1 and in the circumferential direction (around) of the user’s wrist. Ex. 1009
`
`¶¶[0012], [0019]; see also Ex. 2008 118:3-119:7, 120:5-13, 121:3-15 (Dr. Kenny

`
`above, the board’s length (8, blue) is much shorter than the detecting element’s
`
`length (2, purple) in the circumferential direction. Ex. 1009 ¶¶[0012], [0019],
`
`Figs. 1, 2; see also Ex. 2008 118:3-119:7, 120:5-13, 121:3-15; Ex. 2004 ¶¶36-39.
`
`Taken together, a POSITA would have understood that Ohsaki’s figures and
`
`description show that both Ohsaki’s detecting element (2) and board (8) have a
`
`very pronounced longitudinal directionality and are much longer than they are
`
`wide. Ex. 2004 ¶¶36-39; Ex. 1009 Figs. 1, 2, ¶[0019]. A POSITA would have
`
`understood that the top-down view of Ohsaki’s sensor—including the package,
`
`board, and emitter and detector—would look approximately like the figure below:
`
`
`
`Drawing based on Ohsaki, illustrating the sensor’s rectangular shape
`Ex. 2004 ¶38
`
`This is consistent with the remainder of Ohsaki, which emphasizes that the sensor
`
`has a longitudinal direction that must be aligned with the longitudinal direction of
`
`the user’s arm to prevent slippage. Ex. 1009 ¶[0019]; Ex. 2004 ¶¶36-39.

`
`B. A POSITA Would Not Have Been Motivated To Combine Ohsaki’s
`Board With Aizawa’s Sensor
`
`Petitioner fails to show the cited art would have led a POSITA to Masimo’s
`
`claims. Petitioner argues a POSITA would have modified Aizawa’s flat adhesive
`
`acrylic plate “to include a protruding convex surface, similar to Ohsaki’s, to
`
`improve adhesion between the user’s wrist and the sensor, improve detection
`
`efficiency, and protect the elements within the housing.” Pet. 22-23, 47. But
`
`Petitioner fails to show that any of these alleged “motivations” are even present,
`
`much less that they would have motivated a POSITA to create Masimo’s claimed
`
`invention. Ex. 2004 ¶44.
`
`In the sections below, Masimo explains why a POSITA would not have been
`
`motivated to make Petitioner’s proposed combination. First, a POSITA would
`
`have understood that Ohsaki’s rectangular board would be incompatible with
`
`Aizawa’s circular sensor arrangement, undercutting any motivation to improve
`
`adhesion to the user’s tissue. Second, a POSITA would have understood that to
`
`obtain any benefit from Ohsaki’s board, the sensor must be positioned on the
`
`backhand side of the wrist—far from the arteries on the palm side of the wrist
`
`where Aizawa’s sensor takes its pulse measurements. Third, a POSITA would
`
`have believed that adding a convex-shaped cover would direct light away from
`
`Aizawa’s peripherally located detectors, resulting in reduced signal strength and
`
`decreased detection efficiency. Finally, a POSITA would not have replaced

`Apple v. Masimo
`
`Aizawa’s flat adhesive acrylic plate with Ohsaki’s translucent board for the
`
`purpose of protecting Aizawa’s sensor elements because Ohsaki’s translucent
`
`board would introduce complications and concerns. Ex. 2004 ¶45.

`
`a) Modifying Ohsaki’s Rectangular Board Would Eliminate
`Ohsaki’s Already Limited Advantages
`
`Petitioner’s
`
`illustrated combination
`
`fundamentally changes Ohsaki’s
`
`structure and eliminates the longitudinal shape that gives Ohsaki’s translucent
`
`board the ability to prevent slipping. Pet. 22-23; Ex. 1009 ¶[0019]; Ex. 2004 ¶¶46-
`
`47. Petitioner’s illustrated combination changes Ohsaki’s rectangular translucent
`
`board and makes it circular so that it covers Aizawa’s holder 23 (in green, below):

`
`Petitioner claims a POSITA would have been motivated to add Ohsaki’s
`
`board to Aizawa’s circular sensor to improve adhesion. Pet.20, 22-23, 47, 49.3
`
`But Petitioner’s proposed modification eliminates the longitudinal shape that
`
`Ohsaki specifically identifies as important for the benefit of reducing slipping. Ex.
`
`1009 ¶[0019]; Ex. 2004 ¶¶46-47.
`
`Specifically, Ohsaki places a longitudinal sensor on the backhand side of a
`
`user’s wrist to avoid interacting with bones in the wrist. See Ex. 1009 ¶[0006]
`
`(discussing need to avoid pressing on “two bones (the radius and the ulna)”),
`
`¶[0024] (“the radius and the ulna inside the user’s wrist 4 are not pressed”); Ex.
`
`2004 ¶48; see also, e.g., Ex. 1009 ¶¶[0023]-[0024], Abstract, Title, Fig. 1 (Ohsaki
`
`device worn on back side of wrist). Dr. Kenny asserted in deposition for a related
`
`IPR proceeding where the definition of a POSITA is the same as in this proceeding
`
`that a POSITA would have information and knowledge of physiology. Ex. 2007
`
`435:10-20. As illustrated below (left), the forearm bones (the radius and ulna) on
`
`the arm’s backhand (or watch) side create a longitudinal opening at the junction
`
`between the wrist and forearm with no muscle insertions. Ex. 2010 at 49 (Plate
`
`3 Ohsaki does not specifically discuss improving adhesion. Instead,
`
`Petitioner attempts to link Ohaski’s disclosure of a “convex surface [that] prevents
`
`slippage” with “improv[ing] adhesion.” See Pet. 21, 23 (citing Ex. 1009 ¶[0025]);
`
`Ex. 2004 ¶53.

`
`¶¶[0006], [0024]), flank either side of this gap. Ex. 2004 ¶54.

`(partial posterior (back side) view of wrist/forearm from Ex. 2010 at 49 (Plate 434))
`
`
`
`
`Consistent with this anatomy, Ohsaki indicates that the sensor’s longitudinal
`
`direction must be aligned with the longitudinal direction of the user’s arm. Ex.
`
`1009 ¶[0019]; Ex. 2004 ¶49. Ohsaki explains that—in contrast—aligning the
`
`sensor’s longitudinal direction with the circumferential direction of the user’s arm
`
`undesirably results in “a tendency [for Ohsaki’s sensor] to slip off.” Ex. 1009
`
`¶[0019]. As illustrated above (right), a sensor aligned with the circumferential
`
`direction of the user’s wrist undesirably interacts with the radius and the ulna,
`
`which Osaki warns against. Id. ¶¶[0006], [0024]; see also Ex. 2008 132:7-14,
`
`125:20-126:11; Ex. 2004 ¶49.

`Apple v. Masimo
`
`A POSITA would have understood that changing Ohsaki’s rectangular board
`
`into a circular shape would eliminate the advantages discussed above. Ex. 2004
`
`¶50. A circular shape cannot be placed in any longitudinal direction and thus
`
`cannot coincide with the longitudinal direction of the user’s wrist, as taught by
`
`Ohsaki. Instead, a circular shape extends equally in all directions, including in the
`
`circumferential direction of the user’s wrist, which Ohsaki explains results in
`
`slipping. Ex. 1009 ¶[0019]; Ex. 2004 ¶¶50-51. Dr. Kenny acknowledged that
`
`changing a longitudinal structure to a circle eliminates any longitudinal
`
`directionality. Ex. 2008 165:20-166:5. As illustrated below, unlike Ohsaki’s
`
`longitudinal sensor, a circular shape would not fit within the user’s anatomy and
`
`would undesirably press against the user’s radius and ulna, which Ohsaki
`
`specifically cautions against. See Ex. 1009 ¶[0006] (“the user feels uncomfortable
`
`since the radius and the ulna are pressed”); see also id. ¶[0024] (when Ohsaki’s
`
`sensor “is arranged on the back side of the user’s wrist…the radius and ulna inside
`
`the user’s wrist…are not pressed”); Ex. 2004 ¶¶50-51.

`
