WESTPHAL ____________ Appeal 2020-004854 Application 13/530,659 Technology Center 2600 ____________ Before JOHN A. JEFFERY, BRADLEY W. BAUMEISTER, and DENISE M. POTHIER, Administrative Patent Judges. POTHIER, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Appellant1,2 appeals under 35 U.S.C. § 134(a) from the rejection of claims 18, 21-24, 27, and 28. Appeal Br. 1. We AFFIRM. 1 Throughout this opinion, we refer to the Final Action (Final Act.) mailed December 5, 2019, the Appeal Brief (Appeal Br.) filed February 24, 2020, the Examiner’s Answer (Ans.) mailed April 17, 2020, and the Reply Brief (Reply Br.) filed June 12, 2020. 2 “Appellant” refers to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the real party in interest as W.W. Grainger, Inc. Appeal Br. 2. Appeal 2020-004854 Application 13/530,659 2 This appeal returns to us from a prior Board decision, Appeal No. 2018-004138, mailed on June 26, 2019.3 In that decision, we affirmed some of the rejections of then-pending claims 18, 21-24, 27, 28, and 34-39. Claims 34-39 were later canceled. See August 15, 2019 Response, 4. Appellant’s invention relates to input devices for computers, including a computer mouse that provides a touchless input interface. Spec. 1:9-10. In one embodiment, a mouse (e.g., 100) has sensor subsystems (e.g., 114L/114R) that sense surface movements (e.g., user’s finger movements) representing finger gestures, such as finger taps or swipes, proximate to one or both sides of the mouse. Id. at 4:22-5:18, Figs. 1-2. These sensed movements may be used by a computer to cause (1) locations on a computer display to be pointed to or designated or (2) information on the computer display to be moved and/or selected. Id. at 5:15-7:4. Independent claim 18 reads as follows: 18. A computer input device, comprising: a housing in which is carried a main processing circuit; a memory having instructions for controlling operations of the processing circuit; a first integrated touchless sensor subsystem, having a first sensor processing unit, in communication with the main processing circuit sensing a movement of a first user finger in each of three dimensions relative to the computer input device occurring in spaced proximity to the computer input device and providing to the main processing circuit a first signal having data indicative of a direction, speed, and magnitude of the sensed movement of the first user finger; a second integrated touchless sensor subsystem, having a second sensor processing unit, in communication with the main processing circuit sensing a movement of a second user finger 3 In that decision, we noted another prior Board decision, Appeal No. 2015- 007943, mailed May 10, 2017. Appeal 2020-004854 Application 13/530,659 3 in each of three dimensions relative to the computer input device occurring in spaced proximity to the computer input device and providing to the main processing circuit a second signal having data indicative of a direction, speed, and magnitude of the sensed movement of the second user finger; and a transmission circuit under control of the main processing circuit wherein the main processing circuit causes the transmission circuit to transmit to a computer a communication having both the data indicative of the direction, speed, and magnitude of the sensed movement of the first user finger that was provided to the main processing circuit by the first signal and the data indicative of the direction, speed, and magnitude of the sensed movement of the second user finger that was provided to the main processing circuit by the second signal and wherein the first and second integrated touchless sensor subsystems are disposed on opposed sides of the housing of the computer input device. Appeal Br. 9-10 (Claims App.). On the record before us, we are unpersuaded of error. THE MAIN OBVIOUSNESS REJECTION Claims 18, 21, 22,4 24, 27, and 28 are rejected under 35 U.S.C. § 103(a) as being unpatentable over Hinckley (US 6,559,830 B1, issued May 6, 2003), Low (US 2004/0046741 A1, published Mar. 11, 2004), and Hildreth (US 2008/0273755 A1, published Nov. 6, 2008). The Examiner finds that Hinckley teaches most of claim 18’s recitations. Final Act. 2-5 (citing Hinckley 3:46-65, 5:38-55, 6:5-7:15, 7:54-8:5, 8:62-9:3, Figs. 1, 2, 4C, 9); Ans. 4-7 (same). The Examiner states: 4 The heading of the rejection mistakenly includes claim 23 (Final Act. 2), but the rejection’s body does not discuss this claim (id. at 3-10). Appeal 2020-004854 Application 13/530,659 4 Hinckley et al. lacks a first sensor subsystem having a first sensor processing unit in communication with the main processing circuit sensing a movement of a first user finger in each of three dimensions relative to the computer input device occurring in spaced proximity to the computer input device and the first signal having data indicative of a direction, speed, and magnitude of the sensed movement of the first user finger; and a second sensor subsystem having a second sensor processing unit in communication with the processing circuit sensing a movement of a second user finger in each of three dimensions relative to the computer input device occurring in spaced proximity to the computer input device and the second signal having data indicative of a direction, speed, and magnitude of the sensed movement of the second user finger. Final Act. 5. The Examiner relies on Low and Hildreth to teach these features. Id. at 5-8 (citing Low ¶¶ 7, 25-26, 31, 33, 34, 59, Fig. 2; Hildreth ¶¶ 46, 69, 105, 115, 129, 137, Fig. 1); Ans. 7-9 (same). Appellant contends that Hildreth does not expressly describe sensing a magnitude of finger movement but rather measures a finger’s width to determine whether a finger is closer or further away from a camera. Appeal Br. 5-6 (citing Hildreth ¶ 105). For this reason, Appellant argues that “Hildreth does not expressly disclose, teach, or suggest providing a signal having data indicative of a magnitude of the sensed movement of the finger in each of three dimensions . . . .” Id. at 6. Appellant further argues that Hildreth does not teach expressly sensing a speed of a finger’s movement (id.) or determining changes in a finger’s position over time. See id. at 7 (citing Hildreth ¶ 137). For this reason, Appellant contends “Hildreth does not expressly disclose, teach, or suggest providing a signal having data indicative of a speed of the sensed movement of the finger in each of three dimensions . . . .” Id. Appeal 2020-004854 Application 13/530,659 5 Appellant also asserts that Hildreth’s processor that analyzes movements (e.g., changing position and/or orientation) of a finger “is of no consequence” because this teaching fails to disclose, teach, or suggest analyzing finger movement to determine a magnitude or speed of the finger movement. Id. at 6 (citing Hildreth ¶ 73), 8. ISSUE Under § 103, has the Examiner erred in rejecting claim 18 by finding that Hinckley, Low, and Hildreth collectively would have taught or suggested a first integrated touchless sensor subsystem . . . in communication with the main processing circuit sensing a movement of a first user finger in each of three dimensions relative to the computer input device . . . and providing to the main processing circuit a first signal having data indicative of a direction, speed, and magnitude of the sensed movement of the first user finger; [and] a second integrated touchless sensor subsystem . . . in communication with the main processing circuit sensing a movement of a second user finger in each of three dimensions relative to the computer input device . . . and providing to the main processing circuit a second signal having data indicative of a direction, speed, and magnitude of the sensed movement of the second user finger[?] ANALYSIS Based on the record before us, we find no error in the Examiner’s rejection. We select independent claim 18 as representative. See 37 C.F.R. § 41.37(c)(1)(iv). At the outset, Appellant contends that the Examiner Appeal 2020-004854 Application 13/530,659 6 acknowledge[s] that Hinckley/Low does not disclose, teach, or suggest a touchless sensor subsystem that senses a movement of a finger in each of three-dimensions relative to a computer input device occurring in spaced proximity to the computer input device and that provides to a main processing circuit a signal having data indicative of a direction, speed, and magnitude of the sensed movement of the finger. Appeal Br. 4. Regarding the above-italicized language, we disagree. The rejection indicates that Low includes two touchless sensor subsystems (e.g., element 38 in Fig. 2) that are adapted to sense finger movement relative to a computer input device (e.g., finger movement shown as arrow 35 in Figure 2) and provides to a processing circuit a signal having data indicative of a determined direction, speed, and magnitude of the sensed movement. Final Act. 5-7 (citing Low ¶¶ 26, 31, 33, 34, Fig. 2); see also Ans. 15-17 (reproducing Low ¶¶ 25-26, 30-32, Fig. 2); Low ¶ 22. The rejection further proposes to modify Hinckley’s input device (e.g., a mouse/housing with touchless sensors shown in Figs. 4C and 9A-C) with Low’s “directional sensors . . . to translate finger motion into movements on” Hinckley’s display. Final Act. 7 (citing Low ¶ 7); see also id. at 4-6 (citing Hinckley 5:38-55, 6:5-7:15, 7:54-8:5, 8:62-9:3, Figs. 2 (element 120), 4C (elements 200), 9 (elements 692, 696)); see also Ans. 13-15 (reproducing Hinckley 5:38-55, 7:55-8:21, 8:62-9:3, 15:18-27, Figs. 4C, 9A-C). Like Hinckley, Low teaches a housing (e.g., 24) for a mouse having a main processing circuit and one or more movement sensitive areas/sensors (e.g., 28, 38) that implement actions (e.g., movement or commands) “by moving their finger over or on the region of the housing 24.” Low ¶ 24, Figs. 1-2; see id. ¶¶ 22, 26, 31-32, Figs. 1-2 (moving input shown by arrow Appeal 2020-004854 Application 13/530,659 7 35), 4. Specifically, Low teaches when a finger (e.g., 34) moves across a surface (e.g., 32), multiple position signals are generated by optical sensors (e.g., 38) and are “used to determine the direction, position, speed and acceleration of an object as it[’]s moved around the active surface 32” (e.g., senses finger movement). Low ¶ 32 (emphasis added); see id. ¶ 25; see also Ans. 17 (emphasizing the above-quoted language). Low additionally states in one embodiment, that the sensors “measure[] the intensity of light as its reflected off the finger 34” (id. ¶ 32) and teaches at least one type of image acquisition sensor (e.g., Optical Mouse Sensor HDNS-2000) that can “determin[e] the direction and magnitude of movement”5 (id. ¶ 45 (emphasis added)). As such, each of Low’s touchless sensor subsystems senses finger movement in at least one dimension6 relative to a computer input device and 5 The HDNS-2000 sensor measures changes in position by acquiring images “for 1500 times per second and mathematically determining the direction and magnitude of movement” as well as determines “the direction and speed of movement.” Agilent HDNS-2000 Optical Mouse Sensor - Product Brief, p. 1. The Specification states that the “touchless sensor subsystems 114L/114R[,] which are to be used to sense movements of [a] surface, e.g., a user’s hand of fingers” (Spec. 5:1-2) includes “optical sensor packages, e.g., an Agilent ADNS-2030 sensor package” (id. at 5:4-5). The ADNS-2030 sensor similarly “measures changes in position by optically acquiring sequential surface images (frames) and mathematically determining the direction and magnitude of movement.” ADNS-2030 Low Power Optical Mouse Sensor - Data Sheet, p. 1. 6 The HDNS-2000 sensor is described as a “[c]omplete compact 2D sensor,” suggesting that the sensor measures movement in two dimensions. Agilent HDNS-2000 Optical Mouse Sensor - Product Brief, p. 1. The ADNS-2030 sensor (Spec. 4:22-23) is also described as a “[c]omplete 2D motion sensor.” ADNS-2030 Low Power Optical Mouse Sensor - Data Sheet, p. 1. Appeal 2020-004854 Application 13/530,659 8 provides to the main processing circuit a signal having data indicative of a determined direction, speed, and magnitude of the sensed finger movement. Notably, claim 18 recites the sensor subsystems “sensing a movement of a . . . user finger in each of three dimensions” and “providing to the main processing circuit a . . . signal having data indicative of a direction, speed, and magnitude of the sensed movement of the first user finger . . . .” Appeal Br. 9 (Claims App.) (emphasis added). Claim 18 broadly recites sensing a finger movement and providing a signal with data that indicates the direction, speed, and magnitude of the finger’s sensed movement, but does not require that the sensors measure the direction, speed, and magnitude of the finger’s sensed movement. As such, neither Hildreth nor Low needs to sense a magnitude or speed of a finger’s movement to teach claim 18’s recitations, as Appellant argues. See Appeal Br. 5 (asserting Hildreth does not sense a magnitude of a finger’s movement), 6 (asserting Hildreth does not sense a speed of a finger’s movement). Also, regarding the “sensor subsystem . . . sensing a movement of a . . . user finger in each of three dimensions” in claim 18, we stated in the decision, mailed June 26, 2019 (“June 2019 Decision”), that: a sensed tapping movement detects movement in one direction or dimension (e.g., Z direction). See [Low ¶ 23]. Low also teaches sensing a finger moving in the direction of arrow 35 or another direction or dimension. Id. ¶ 31, Fig. 2. Low further discusses sensors 38 can “detect the position of the finger 34 as [it’s] moved over the active surface 32” (id.), including “the positional data (e.g., X and Y)” (id. ¶ 33), and signals “may be used to determine the direction [and] position . . . of the object as [it’s] moved around the active surface 32” (id. ¶ 32). . . . Low’s Figures 3A through 5 also show sensors that detect or monitor “direction of movement” at best in two- Appeal 2020-004854 Application 13/530,659 9 dimensions, but not “three-dimensional direction of movement” as claim 18 requires. June 2019 Decision, 11-12. Since this decision, claim 18 was amended so that claim no longer recites its sensor subsystems are “providing to main processing circuit a . . . signal having data indicative of the sensed three-dimensional direction of movement” of the first and second user fingers. Compare June 2019 Decision, 2) (emphasis added). That is, claim 18 is no longer required to sense 3-D direction of movement (e.g., X, Y, and Z movement), but rather to sense movement in each of three dimensions (e.g., X, Y, or Z movement). Appeal Br. 9 (Claims App.). Thus, as explained above, Low at least suggests sensing movement in each of three dimensions (e.g., X, Y, or Z). See Low ¶¶ 23 (discussing positional data related to movement on the display screen and tapping or Z directional movement), 33 (discussing sensing X and Y positional data). Regardless, the rejection further relies on Hildreth to teach known sensors for sensing a finger’s movement in each of three-dimensions. Final Act. 7-8 (citing Hildreth ¶¶ 46, 69, 105, 115, 129, 137, Fig. 1); see also Ans. 9 (same), 18-20 (reproducing Hildreth ¶¶ 47-48, 69, 105, 129, 137, Fig. 1). Hildreth teaches its processor may determine a position and orientation of finger in “three dimensions.” Hildreth ¶ 46; see id. ¶ 69. Hildreth further discusses a velocity can be “calculated as the difference in position of a fingertip position with an image region (or a three-dimensional image region) . . . .” Id. ¶ 137; see Ans. 21 (noting Hildreth measures “the difference in position of a fingertip (magnitude of the fingertip[’]s movement)”). Hildreth also discusses translating or zooming a view point Appeal 2020-004854 Application 13/530,659 10 based on the fingertip position. Hildreth ¶ 137. As such, Hildreth’s teachings, when combined with the Hinckley/Low touchless sensor subsystems, would have predictably yielded no more than two touchless sensor subsystems that “sens[e] a movement of” a user fingers “in each of three-dimensions relative to the computer input device” and “provid[e] to the main processing circuit” “signal[s] having data indicative of a direction, speed, and magnitude of the sensed movement of the” user fingers, as claim 18 recites. Regarding Appellant’s contention that Hildreth only measures a finger’s width to detect movement in the Z direction and thus does not teach or suggest providing a signal indicative of a magnitude of the finger’s sensed movement in each of three dimensions (Appeal Br. 5-6; see also Reply Br. 4-5), we explained above that claim 18 does not require sensing the magnitude of the finger’s movement but rather only recites sensing finger movement in each of three dimensions and providing a signal having data indicative of the magnitude of the sensed finger movement. Furthermore, Hildreth’s disputed paragraph 105 is just one way of estimating a 3-D position. More generally, Hildreth states position data “may estimate a distance of the finger from the camera based on the size of the finger or may process images captured from a stereo or time-of-flight camera, which include depth information.” Hildreth ¶ 69 (emphases added). Thus, Hildreth is not limited to using finger width measurements. Hildreth also teaches its processor “may compute a vector that represents a position and orientation of a detected finger in three- dimensional space” (Hildreth ¶ 69 (emphasis added)), further suggesting that it processes the sensed information (see id. ¶¶ 69, 73) and provides signal Appeal 2020-004854 Application 13/530,659 11 indicating not only a position but magnitude of the sensed movement in each of three dimensions. Hildreth thus teaches or at least suggests embodiments that provide a “signal having data indicative of a . . . magnitude . . . of the sensed movement of the” user’s fingers in each of three-dimensions as claim 18 recites. As to Hildreth’s disputed paragraph 137 (Appeal Br. 6-7), Low, as previously explained, teaches providing a signal indicative of a speed of finger’s sensed movement, such that Hildreth need not provide a teaching in this regard. Low ¶ 32; see id. ¶ 45. In any event, Hildreth supplements Low’s teachings. Hildreth teaches a known technique for calculating a velocity based on the difference in a fingertip’s position relative to center position, a 3-D image region, a border of a sub-region within the image region. Hildreth ¶ 137. Additionally, Hildreth discusses the position difference can be used to rotate horizontally and vertically (e.g., scrolling) the view point in a virtual environment. Id. We thus disagree with Appellant that Hildreth does not teach or at least suggests determining the change in a finger’s position over time. See Ans. 22-23; see also Hildreth ¶ 73 (stating “processor may analyze movement (e.g., changing position and/or orientation) of a detected finger”) (emphases added). Hildreth therefore teaches and suggests a processor that is part of sensor subsystem that senses a finger’s movement based on changes in fingertip’s or finger’s position and provides a signal having data indicative of the speed of a finger’s sensed movement as claim 18 requires. In the Reply Brief, Appellant argues that Hildreth fails to disclose a time reference is being used and thus it cannot teach or suggest “this claimed element.” Reply Br. 2. Claim 18 recites first and second “touchless sensor Appeal 2020-004854 Application 13/530,659 12 subsystems . . . sensing a movement of” first and second fingers “in each of three dimensions” and “providing to the main processing circuit a . . . signal having data indicative of . . . speed . . . of the sensed movement of the” first and second fingers. Appeal Br. 9 (Claims App.). There is no recitation to a time reference. Even assuming, without deciding, that a time reference is implied in the “speed” recitation, identity of terminology between Hildreth and the claim language is not required to teach or suggest the limitations in claims. See In re Bond, 910 F.2d 831, 832 (Fed. Cir. 1990). As previously explained, both Low and Hildreth teach sensing a finger’s movement and providing a signal indicative of the speed of a finger’s movement. Appellant also argues that Hildreth calculates a velocity when the fingertip’s position does not change and is based only on a single finger position, not positions. Reply Br. 3-4 (citing Hildreth ¶ 137). Putting aside whether this argument is being raised for the first time in the Reply Brief and is untimely (see 37 C.F.R. § 41.41(b)(2)), we reiterate that claim 18 does not recite that the sensor subsystems sense (a) a change in finger positions or (b) a velocity of a finger’s movement, but rather just “sens[e] a movement of a . . . user finger” and “provid[e] to the main processing circuit a . . . signal having data indicative of a direction, speed, and magnitude of the sensed movement of the . . . user finger.” Appeal Br. 9 (Claims App.) (emphases added). Thus, regardless of how Hildreth senses movement, Hildreth teaches and suggests determining a speed of the sensed finger movement and sensor subsystems “provid[e] to the main processing circuit a . . . signal having data indicative of a . . . speed . . . of the sensed movement of the . . . user finger” as claim 18 recites as previously explained. Appeal 2020-004854 Application 13/530,659 13 Lastly, to the extent Appellant contends Hildreth fails to disclose explicitly the features in dispute (see Appeal Br. 6, 8), the Examiner does not rely on inherency to supply missing claim limitations in connection with the obviousness rejection. See Final Act. 2-8. Rather, the rejection relies on what the cited references’ collective teachings would have suggested to ordinarily skilled artisans. Thus, Appellant’s inherency-based arguments are inapposite and, therefore, unavailing. See Merck & Co. v. Biocraft Laboratories, Inc,, 874 F.2d 804, 807 (Fed. Cir. 1989) (“[T]he question under 35 U.S.C. § 103 is not merely what the references expressly teach but what they would have suggested to one of ordinary skill in the art at the time the invention was made.”) (quoting In re Lamberti, 545 F.2d 747, 750 (CCPA 1976)) (internal quotation marks omitted) (emphasis added). For the foregoing reasons, Appellant has not persuaded us of error in the rejection of independent claim 18 and claims 21, 22, 24, 27, and 28, which are not argued separately. THE REMAINING OBVIOUSNESS REJECTION Claim 23 is rejected under 35 U.S.C. § 103(a) as being unpatentable over Hinckley, Low, Hildreth, and Bohn (US 2003/0006965, published Jan. 9, 2003). Final Act. 10-11. Claim 23 depends from claim 18 and is not separately argued. We therefore sustain this rejection for the reasons similar to those previously discussed.
