“Petitioner argues that at the relevant time of the invention claimed in the ’849 patent (April 2005),2 a person of ordinary skill in the art would have had “at least a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent field requiring learning computation principles, and two years of work experience in networking or streaming media systems, particularly audio and video, over the Internet,” where “[a]dditional education could compensate for less practical experience and vice versa.” Pet. 5–6 (citing Ex. 1002 ¶¶ 18–23). In the Decision on Institution, the Board agreed with and applied Petitioner’s proposed definition. Dec. on Inst. 9–11. Patent Owner proposes a very similar definition of “a bachelor’s degree in electrical engineering, computer engineering, computer science, or a related field, and two to three years of experience in the design or development of (1) video processing systems, audio processing systems, and/or the equivalent; and (2) networking and communications systems, or the equivalent,” where “[a]dditional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education.” PO Resp. 23 2 Petitioner states that it “uses [the earliest possible priority date of April 18, 2005] as the priority date of the challenged claims.” Pet. 6. Patent Owner agrees that the “earliest effective filing date” of the challenged claims is April 18, 2005. PO Resp. 19. The ’849 patent is expired. See Ex. 1001, codes (63), (*); Paper 8, 33. would be the same under either level” of ordinary skill in the art. Id. Based on the full record developed during trial, including our review of the ’849 patent and the types of problems and solutions described in the ’849 patent and cited prior art, we maintain the previously adopted definition of the level of ordinary skill in the art, but remove the term “at least” to avoid unnecessary ambiguity. Our analysis herein, however, would be the same under either party’s proposed definition.” slip op. at 7

“37 C.F.R. § 42.100(b). Petitioner states in the Petition that it “does not presently contend that any term requires express construction.” Pet. 6. Patent Owner “does not believe any terms of the ’849 [p]atent require express constructions for purposes of” this proceeding. PO Resp. 24; Sur-Reply 11. The Board did not interpret any terms in the Decision on Institution. Dec. on Inst. 8. We agree that no terms require express interpretation to determine whether Petitioner has met its burden to prove unpatentability of the challenged claims. See Nidec Motor Corp. v.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundUnpatentable
“Finally, Petitioner explains in detail why and how a person of ordinary skill in the art would have had reason to combine the teachings of Carmel and Mattavelli, with a reasonable expectation of success. See Pet. 50–55. Specifically, an ordinarily skilled artisan would have modified Carmel’s system to use “Mattavelli’s CGD techniques to optimize the decoding of in more efficient network bandwidth usage and improved playback of multimedia data streams. Id. at 50, 52–53, 55. Petitioner contends that Carmel and Mattavelli are both directed to processing multimedia data playback “for the appreciation of a user,” while providing the highest perceived audio and video output quality possible in view of system constraints to ensure playback continuity. Id. at 50–51 (citing Ex. 1003, 7:35–49, 10:48–54, 11:9–18, Figs. 3D, 6B; Ex. 1004, 2309–10). Petitioner argues that Carmel and Mattavelli both pertain to compression of multimedia data using well-known coding and compression standards for video streaming. Id. at 51 (citing Ex. 1003, 7:25–26, 11:24–52; Ex. 1004, 2309–11). Petitioner further asserts that a person of ordinary skill in the art would have appreciated that Carmel and Mattavelli “complement[]” each other because Carmel addresses constraints on available network bandwidth and Mattavelli addresses limits on available processing resources at the client/multimedia player. Pet. 52 (citing Ex. 1003, code (57), 7:36–41; Ex. 1004, 2309–2312). According to Petitioner, an ordinarily skilled artisan would have been motivated to combine the complementary teachings in Carmel and Mattavelli to create a more robust streaming system that addresses both bandwidth constraints and client processing limits to provide the best possible playback experience. Id. (citing Ex. 1002 ¶¶ 212–215). Petitioner also contends that Mattavelli teaches that merely optimizing transmission bandwidth is not sufficient and is potentially harmful, which provides an express motivation to combine Carmel’s and Mattavelli’s complementary teachings to ensure that different, related links in the streaming playback chain are optimized together. Id. at 53 (citing Ex. 1002 express disclosure that would have motivated a person of ordinary skill in the art to incorporate Mattavelli’s complementary teachings regarding decoding because Carmel states that multimedia playback is achieved “preferably with only a minimal necessary transmission and decoding delay.” Id. at 53–54 (quoting Ex. 1003, 10:50–54; citing Ex. 1002 ¶ 218). Patent Owner in its Response does not dispute that Carmel and Mattavelli teach the preamble and limitations 1[a.i]–1[c.i], or that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner.6 Nonetheless, the burden remains on Petitioner to demonstrate unpatentability.

According to Petitioner, a “person with a different degree but with additional relevant experience could still qualify if the additional experience compensates for the different educational background.” Id. Petitioner also asserts a “person with less than 2 years of experience working in a field involving wireless communications could still qualify if the person has additional education that compensate[s] for their lesser experience.” Id. Patent Owner does not dispute Petitioner’s proposed level of skill. See generally PO Resp. We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended. Otherwise, we adopt Petitioner’s formulation of the level of ordinary skill in the art, because it appears consistent with the ’463 Patent Specification and the prior art of record.” slip op. at 8

“We do not agree with Patent Owner’s arguments disputing Petitioner’s backward compatibility rationale for combining the teachings of Yan and Takeda. Patent Owner’s arguments are misplaced because they are premised incorrectly on Takeda’s teachings being limited to 5G NR (i.e., standalone 5G NR), and the proposed combination requiring “mixing standards and behaviors.” To the contrary, Petitioner explicitly asserts that “Takeda states that its teachings are applicable to both 4G and 5G”––i.e., non-standalone 5G. Pet. 14 (citing Ex. 1007 ¶ 239). Likewise, instead of mixing 5G and 4G standards and behaviors as argued by Patent Owner, Petitioner merely proposes retaining Yan’s 4G method of allocating UL channel resources sets with Takeda’s teaching of 5G NR BWPs. See Pet. 14–15. We credit Dr. Roy’s testimony that a person of ordinary skill in the art would have been motivated to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network capability because it is supported by the cited evidence of record. See Ex. 1002 ¶¶ 105, 106 (citing Ex. 1007 ¶ 239; Ex. 1031, 1, 3; Ex. 1033, 5:23–31; Ex. 1034, 10; Ex. 1035, 1, 5; Ex. 1037, 31). Moreover, as pointed out by Petitioner, Dr. Shimony’s deposition testimony regarding the usefulness of backward compatibility and the importance of a non-standalone UE having the ability to communicate over both 4G and 5G standards supports Dr. Roy’s testimony, yet undermines Patent Owner’s arguments. See Ex. 1050, 178:16–182:16; Pet. Reply 14–15. Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network compatibility.10 See Pet. 13–15; KSR, 550 U.S. at 418.” slip op. at 15

“With respect to Petitioner’s allegations that rest on AAPA, we determine Petitioner has failed to show that claims 2, 10, and 11 are unpatentable. Our rules require that a petition for inter partes review must base the asserted challenges on “prior art consisting of patents or printed publications.” 35 U.S.C. § 311(b); 37 C.F.R. § 42.104(b)(2) and (4). And, a petitioner who relies on applicant admitted prior art as the basis, or part of the basis, of a ground, runs afoul of § 311. Qualcomm, 134 F.4th at 1365; see also USPTO Memorandum, Enforcement and Non-Waiver of 37 C.F.R. § 42.104(b)(4) and Permissible Uses of General Knowledge in Inter Partes Reviews (Jul. 21, 2025), available at www.uspto.gov/sites/default/ files/documents/aapa_memo_final__signed.pdf. We acknowledge but reject Petitioner’s position that its combinations discussing AAPA do not “rely” on AAPA but rather rely on U.S. Patent No. 5,793,185 (“the ’185 patent”), described in the ’203 patent as prior art. Pet. Reply 26. A petition for inter partes review must identify, “in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104 (b)(4). Here, Petitioner’s contention that the Grounds 2 and 5 actually rely on the ’185 patent when discussing AAPA is inconsistent with the Petition. In particular, the Petition does not cite to or direct our attention to any specific details from the ’185 patent to support its challenges. See generally Pet. 54–57, 76–77. Accordingly, Petitioner has failed to show, by a preponderance of the evidence, that claims 2, 10, and 11 would have been unpatentable over the combination of Richardson, Zhao, and AAPA as well as over the combination of Yu, Paparrizos, and AAPA.

Claims 1–4 and 6 are unpatentable under §103 because the prior-art combinations teach the limitations at issue under the Federal Circuit’s construction of “style.”
RulingsRemand decision- RemandDecided for petitioner
“We agree with Petitioner. Lemay Web discloses that the style settings of width, height, pause, and repeat for the pocket watch images can be changed by changing the values for width, height, pause, and repeat in the HTML file. Ex. 1004, 89–90. This results in changing the size, duration, and frequency of the display of the multiple pocket watch image objects without changing the image files or the Java applet. Id. That is, the 12 image objects of Lemay Web can be uniformly formatted by applying and altering the style settings of the HTML file, which is stored separately from the image objects and the Java applet. Id. at 88– 89. In our Final Written Decision, we wrote that “Lemay Web discloses that the image files that are displayed as the animation object are separate from the HTML.” Ex. 1004, 88–89.” Dec. 22. The Federal Circuit wrote that “how the Board evaluated what constitutes separateness in the prior art software is less than clear.” Opinion, 13 n.7. To be clear, the animation of Lemay Web comprises 12 different pocket watch image objects. Ex. 1004, 89. The HTML file that contains the style settings for the 12 different pocket watch image objects is stored separately from the 12 different pocket watch image objects. Id. at 88–91. The style of the 12 different pocket watch image objects can be altered by changing the values of the style settings in the separate HTML file, thus allowing the style to be uniformly applied to each of the associated 12 pocket watch image objects when the pocket watch image objects are created on the web page. Id.; see Ex. 1030 ¶¶ 28–29; Dec. 21–22. In conclusion for issue (B), we find that Lemay Web teaches applying the style located in the separate HTML file to the pocket watch image objects when creating the pocket watch image objects on the web page. Therefore, Lemay Web’s style is “defined separately from any single object” as claimed. Because Lemay Web’s style can be applied to one object and more than one object and Lemay Web’s style is defined separately from any single object, we find that the prior art combination teaches limitations 1(c) and 1(g) under the proper construction of “style.”” slip op. at 12

“What you see in the bottom right is an excerpt from the Lemay Web book . . . [y]ou can still use the Java applet just by putting this applet code into your HTML file. So this shows the animator class is going to be run within height or how big a window within the browser should be allocated in this applet. You can . . . tell the animator class how long to pause in between each image. So that’s a style that’s being applied to all of the multiple images that make up this animation. Ex. 2029, 746:23–747:7. Patent Owner then asked GoDaddy’s expert “for each unique animation you want to create with this animator class that’s shown here, you’re going to have to have a unique set of HTML code with the settings along with any of the images you’ll want to associate with the animator class, right?” Ex. 2030, 793:7–11. GoDaddy’s expert testified, with reference to Exhibit 2027, 80, that “Yeah. I’m not a hundred percent sure I understand your question, but yes, if you had six animations on a page, for example, you’d have six blocks of markup that looked like the markup at the bottom right of that slide, starting with applet.” Id. at 793:12–16. In addressing Patent Owner’s question about “each unique animation,” GoDaddy’s expert provided a hypothetical example of a web page having six animations, and explained that the six animations have six blocks of markup. Ex. 2030, 793:13–16. We find that this testimony means that if a web page has six unique animations, then for each unique animation, a corresponding HTML file contains the style settings for the image objects of that animation, such that the “six animations on a page . . . have six blocks of markup.” Id. We find that the subsequent testimony of GoDaddy’s expert cited by Patent Owner is consistent with the expert’s initial testimony that Lemay Web’s style is “applied to all of the multiple images that make up this animation.” Ex. 2029, 747:5–7. We also find that the subsequent testimony is consistent with and supported by the disclosure of Lemay Web, which teaches that an animation has a set of image files and is added to a Web page using the Animator applet. Ex. 1004, 88 (“[Y]ou’ll learn just enough about Java applets to set up animation on your Web page. . . . To create animation using Java and the Animator applet, you’ll need . . . [a] set of image files . . . that make up your animation.”); see id. at 88–91.

“As directed by the Federal Circuit, we determine whether the prior art combination teaches limitations 1(c) and 1(g) under the proper construction of “style,” but otherwise do not revisit our analysis of claim 1. Remand Opinion 7, 13–14. The Federal Circuit construed “style” to mean “a collection of one or more settings that is defined separately from any single object but can be associated with one or more objects,” with the understanding that “associated with one or more” means capable of being associated with both one object and more than one object.

“We agree with Petitioner. As discussed above, the plain meaning of an “image object” read in light of the Specification encompasses data that defines an image, such as each of the 12 different pocket watch images of Lemay Web. Ex. 1004, 89–90. Therefore, the HTML file of Lemay Web, which specifies attributes including width, height, pause value, and repeat value of the pocket watch image objects, is “capable of being applied to more than one” image object, such as each of the 12 different pocket watch image objects described by Lemay Web.

“We agree with Petitioner. The Board and Petitioner understood the meaning of “or” in the phrase “one or more objects” in Patent Owner’s proposed construction of style as meaning that “a style . . . can be associated with just one object.” Dec. 22; see Reply 4–5. The Federal Circuit “ultimately conclude[d] that Express Mobile’s proposed construction, with ‘or’ properly interpreted,” means “that the claimed ‘style’ must be capable of being applied to both one and more than one ‘object,’” and “remand[ed] for further proceedings in view of the correct claim construction.” Remand Opinion 13. In doing so, the Federal Circuit stated that “[i]t may be that under the correct claim construction, the Board finds that Lemay Web teaches the claimed ‘style’; however, that is still an open fact question for the Board to decide in the first instance.” Id. at n.6. Given that the Federal Circuit has ordered the Board to determine whether the prior art teaches the claimed “style” under the proper construction, we find that Petitioner’s arguments on this issue are timely.” slip op. at 6

“Contrary to Patent Owner’s contention, the Specification discloses, “Data that defines text button, image, paragraph, or other parent objects . . . can be stored in two-dimensional arrays (by web page and by object number).” Ex. 1001, 22:11–13 (emphasis added). The Specification further discloses that “objects . . . include colors, fonts, images, audio clips, video clips, text areas, URLs and thread objects.” Id. at 2:16–17 (emphasis added); see id. at 8:40. We highlight that the Specification’s use of “object” is consistent with a definition of “object” in the computing art at the time of the invention, which is “(2) A passive entity that contains or receives data; for example, bytes, blocks, clocks fields, files . . . .” George McDaniel, IBM Dictionary of Computing, McGraw-Hill, Inc. 1994, p. 471 (Ex. 3001). Because the Specification discloses that data defines an object, we construe the plain meaning of the claimed “object,” read in light of the Specification of the ’168 patent, as encompassing data that defines the object. See Phillips v. AWH Corp., 415 F.3d 1303, 1315 (Fed. Cir. 2005) (The “specification . . . is the single best guide to the meaning of a disputed term.”); Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed. Cir. 1996); (Excluding an embodiment in the specification from “the scope of the patent claim . . . is rarely, if ever, correct.”). Further, because the Specification discloses that data defines image objects, and that objects include images, we construe the plain meaning of the claimed “image object,” read in light of the Specification, as encompassing data that defines an image, such as one of the 12 different pocket watch images of Lemay Web.” slip op. at 8

“The respective proposed levels of qualifications for a person of ordinary skill in the art are similar, with Patent Owner proposing two years of experience compared to Petitioner proposing significant experience with remotely controlling fluid-handling devices, like SCADA systems. Patent Owner also proposes more extensive experience in lieu of educational experience. While we find Petitioner’s proposed qualifications to be acceptable, we adopt Patent Owner’s proposed qualifications for the purposes of this Decision because they offer a wider range of qualifications that nonetheless comport with the level of skill necessary to understand and implement the teachings of the ’871 patent and the asserted prior art.

We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient. See Ex. 1005, 10:62–67, 14:35– 15:2, 15:62–16:32; see also Pet. 12–14, 16–18. Kahn discloses that “the communication unit 112B can include on-site alerts such as optical (indicator lights), audible alerts (e.g., alarm sounds), tactile (e.g., vibration of the unit) or can be interfaced to an appropriate control valve for simply shutting off the supply of fluid upon the detection of emergency events, for instance.” Ex. 1005, 10:62–67. Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively. Rather, the disclosure indicates that the communication unit 112B includes on-site alerts and that the local (non-remote) communication unit 112B can be interfaced with the control valve.” slip op. at 18

“time it was made, we consider the level of ordinary skill in the pertinent art at the time of the invention. Graham, 383 U.S. at 17. “The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.” Ryko Mfg. Co. v. Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991). The “person having ordinary skill in the art” is a hypothetical construct, from whose vantage point obviousness is assessed. In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Factors pertinent to a determination of the level of ordinary skill in the art include “(1) the educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of active workers in the field.” Env’t Designs, Ltd. v. Union Oil Co. of Cal., 713 F.2d 693, 696 (Fed. Cir. 1983) (citing Orthopedic Equip. Co. v. All Orthopedic Appliances, Inc., 707 F.2d 1376, 1381–82 (Fed.

Work experience could substitute for formal education and additional formal education could substitute for work experience. Pet. 7 (citing Ex. 1002 ¶¶ 28–32). In the Preliminary Response, SoundClear does not address Amazon’s assessment of the level of skill in the art. See Prelim. Resp. At this stage of the proceeding, we adopt Amazon’s uncontested assessment of the level of skill in the art because (1) it is consistent with the ’675 patent and the asserted prior art; and (2) it is supported by the testimony of Dr. Stern.” slip op. at 12

“arguments and evidence for purposes of institution that would support determining that a person of ordinary skill in the would have been motivated to combine the teachings of Shin and Aoyama. As one example, Amazon contends that the proposed combination is merely the addition of one known element (i.e., “Aoyama’s natural language processing and information retrieval”) to another known element (i.e., “Shin’s voice processing and response device”) to obtain predictable results (i.e., “identifying a user’s intent and providing information responsive to such intent”). Pet. 19–20 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 83). As another example, Amazon contends the proposed combination also represents the addition of one known element (i.e., “Aoyama’s word replacement” feature) to another known element (i.e., “Shin’s distance-based content abbreviation/simplification”) to obtain predictable results (i.e., “using word replacement to simply content for distant users”). Id. at 25–26 (citing KSR, 550 U.S. at 417; Ex. 1002 ¶ 100). Amazon also presents sufficient arguments and evidence for purposes of institution that would support determining there is a reasonable expectation of success in making the proposed combination. Id. at 20 (citing Ex. 1002 ¶ 84), 27–28 (citing Ex. 1002 ¶ 102; Ex. 1011 ¶¶ 97, 98 Fig. 7). To the extent SoundClear argues that Amazon is required to identify a problem a person of ordinary skill in the art would have sought to solve when combining the teachings of Shin and Aoyama, we do not agree. See Prelim. Resp. 31–32. This line of argument runs contrary to the principles of law articulated in KSR. In KSR, the Supreme Court emphasized “an expansive and flexible approach” to an obviousness evaluation. KSR, 550 U.S. at 415; see also Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347, 1363 (Fed. Cir. 2018) (“KSR did not impose a rigid requirement to identify . . . a problem to be solved in the art . . . .”). The Supreme Court stated that, “[o]ften, it will be necessary for a court to look to interrelated teachings of multiple patents,” amongst other things, “to determine whether there was apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418. Moreover, the Supreme Court explained that, “[u]nder the correct analysis, any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Id. at 420.” slip op. at 26

“Based on the preliminary record, we discern no deficiency in Amazon’s characterizations of Shin, Aoyama, or the general background knowledge in the art. In addition, for purposes of institution, we are persuaded by Dr. Stern’s testimony concerning the relevant disclosures in Shin and Aoyama. At this stage of the proceeding, SoundClear argues that Shin does not teach limitations 1[b]—“a voice classifying unit configured 1[b][i] to calculate a distance between the user and the output-content control device by a proximity sensor 1[b][ii] to classify the voice into either a first voice or a second voice based on the calculated distance.” See Prelim. Resp. 19–22. a. Limitations 1[b]—“a voice classifying unit configured to 1[b][i] calculate a distance between the user and the output-content control device by a proximity sensor to 1[b][ii] classify the voice into either a first voice or a second voice based on the calculated distance” In the Preliminary Response, SoundClear contends that Shin fails to teach voice classification because “Shin is incapable of distinguishing [between] multiple voices.” Prelim. Resp. 21. More specifically, SoundClear argues that Shin cannot teach classifying a voice into a first voice or second voice because “Shin never refers to a ‘first user’ or ‘second user’ or ‘multiple users.’” Id. (citing Ex. 1003 generally); see also id. at 26– 27 (arguing that Amazon misstates the record because Shin never discloses a “first voice” nor a “second voice”). Instead, SoundClear asserts that Shin only contemplates a single user (i.e., user 10) when calculating the distance between the user and an electronic device (e.g., Shin’s electronic device 100). Id. at 21–22 (citing Ex. 1003 ¶¶ 37, 38). Based on the preliminary record, Amazon presents sufficient evidence that would support a finding that Shin teaches “a voice classifying unit configured to calculate a distance between the user and the output-content control device by a proximity sensor to classify the voice into either a first voice or a second voice based on the calculated distance.” Pet. 10–14. Shin discloses that “processor 120 may determine an output scheme of corresponding content based on a distance between a user and the electronic device 101.” Ex. 1003 ¶ 53. Shin’s processor 120 accomplishes this distance calculation by using distance detection module 180, which may include various sensors, such as a proximity sensor. Id. ¶ 66; see also id. ¶ 153 (disclosing an embodiment where electronic device 901 includes sensor module 940, which, in turn, includes proximity sensor 940G). Shin’s Table 3 illustrates how the distance between the user and electronic device 101 determines the output scheme. Id. ¶ 86, Table 3. For instance, Shin’s Table 3 illustrates classifying the user’s voice input as a “first voice” when the distance between the user and electronic device 101 is between 1 to 2 meters, and classifying the user’s voice input as a “second voice” when the distance between the user and electronic device 101 is less than 1 meter.
