RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“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. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“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.

“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.

Relying on the testimony of Dr. Stern, Amazon argues the following: [a] person of ordinary skill in the art . . . would have had a minimum of a bachelor’s degree in computer engineering, computer science, electrical engineering, or a similar field, and approximately two years of industry or academic experience in a field related to controlling the audio output of electronic devices. 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.

“1. Principles of Law A claim is unpatentable under § 103 if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, “would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v.

Ex. 1005, 12:9–16. This particular disclosure, however, does not appear to implicate the functionality of Hankins’s controller 350, much less result in controller 350 generating a list of available tunnel servers that would allow gateway devices 311 and 312 to exchange a listing of “services” therebetween. Petitioner’s reliance on Hankins’s controller 350 provisioning additional tunnel servers both to improve performance and without human intervention fares no better. Ex. 1005, 25:45–55.

“The parties agree that the proposed levels of ordinary skill in the art are “not materially different.” PO Resp. 4; Reply 2. The difference, essentially, is that Patent Owner more explicitly describes the members on the interdisciplinary team, and argues that it would be necessary to consult with such individuals, particularly with persons experienced in dentistry or orthodontics, whereas Petitioner’s proposal states that one “could” consult with such individuals. However, Patent Owner’s argument that it would be necessary for a person of ordinary skill in the art to consult with an individual having experience in dentistry and/or orthodontics is narrower than Patent Owner’s proposed level of skill in the art, which describes “individuals familiar with medical imaging, dental imaging, dentistry, and/or orthodontics.” PO Resp. 4 (emphasis omitted, emphasis added). Neither party presents any argument explaining how the differences in the respective educational backgrounds and work experience in the proposed definitions affect the dispute. Having considered the parties’ respective arguments and the evidence of record, we adopt a modified version of the parties’ proposals, and determine for purposes of this Decision that a person of ordinary skill in the art would have an advanced degree, such as a Masters’ Degree or Ph.D. in computer science, computer engineering, electrical engineering, or a related field, with at least two years of work in computer vision, image analysis, medical imaging, or related areas. Further, a person of ordinary skill in the art could have less education but significant professional experience in one or more of these fields, and could be a member of an interdisciplinary team which would have included individuals familiar with medical imaging, dental imaging, dentistry, and/or orthodontics.” slip op. at 10

“We are satisfied that Dr. Foroosh qualifies as a person of ordinary skill in the art. First, Dr. Foroosh has the required educational background, with, for example, a Bachelor of Science in Electrical Engineering, a Master of Science in Electrical Engineering, a Master of Science in Computer Science and Engineering, and a Ph.D in Computer Science. Ex. 1003, 7; Ex. 1002 ¶ 3. Second, Dr. Foroosh has the required work experience, with, for example, research in machine learning, deep learning, and neural networks, image and video processing and analysis, and computer vision. Ex. 1003, 2, 4–8; see also id. at 9–13 (list of projects), 14–29 (list of publications), 32 (list of interdisciplinary research); Ex. 1002 ¶¶ 2–5 (describing work experience), 6–9 (describing research experience). Dr. Foroosh has also been part of interdisciplinary research efforts including those relating to the medical or dental fields, such as, research on the intersection of computer vision and augmented reality in medical and surgical interventions. Ex. 1003, 32; Ex. 1002 ¶ 12. Dr. Foroosh describes a research project, Modeling and Visualization of Muscoloskeletal Structures in Dental CT-Scan (2006–2007), where he “developed algorithms for [threedimensional (‘3D’)] registration, modeling and visualization of maxilla and mandible of patients for dental surgery using Computer Aided Tomography (CAT) scanning.” Ex. 1002 ¶ 6. He describes another project for the National Science Foundation, which “was directed to the registration/alignment of dental CT scans of patients over a period of time during the treatment of a patient, with the purpose of improving the quality of 3D models, e.g., corrections and noise removal in 3D CT scans.” Id. ¶ 7. He was also a co-author on Alignment of Maxillofacial CT Scans to Stone- Cast Models Using 3D Symmetry for Backscattering Artifact Reduction, Proceedings of Medical Image Understanding and Analysis Conference (MIUA) (2006), and an adviser for a dissertation directed to “Sub-pixel Registration in Computational Imaging and Applications to Enhancement of Maxillofacial CT Data,” which “focused on registration and alignment of 2D images and 3D digitized data obtained by dental CT scans and dental imprints of a patient.” Id. ¶¶ 8, 9. Although Dr. Foroosh is not a dentist or orthodontist, we determine that the breadth of his background, as fully set forth in Exhibit 1003, qualifies him to provide testimony from the perspective of a person of ordinary skill in the art. In short, we agree with Petitioner that Dr. Foroosh has “ample experience with medical and dental imaging,” as set forth above. Reply 2 (citing Ex. 1002 ¶¶ 6–9; Ex. 1003, 14, 15, 21, 26, 32). Moreover, we are afforded broad discretion in assigning weight that is to be accorded expert testimony. See Yorkey v. Diab, 601 F.3d 1279, 1284 (Fed.

“proposed constructions. As there is no dispute between the parties, and after reviewing the complete record, we determine that express construction of “interior tooth outline,” “exterior tooth outline,” and “shape of an orthodontic aligner” is not necessary for purposes of this Decision. Further, Patent Owner does not dispute Petitioner’s interpretation of limitations 1(1) and 1(2), or Petitioner’s identification of the corresponding function and structure in limitation 1(3). We agree with Petitioner that step 2 of claim 1 recites a conditional limitation, that, if met, is not needed to be performed. See, e.g., Cybersettle, Inc. v. Nat’l Arbitration Forum, 243 F. App’x 603, 607 (Fed. Cir. 2007) (“It is of course true that methods steps may be contingent. If the condition for performing a contingent step is not satisfied, the performance recited by the step need not be carried out in order for the claimed method to be performed.”). This is supported by the Specification: In one embodiment, the dentition image is the aligner image. In other words, the same updated image makes it possible not only to see the aligner outline 28 but also to see the dentition outline 16, through the aligner (FIG. 3). This single image therefore makes it possible to compare aligner 20 and dentition outlines. Advantageously, readjustment step 2), described later, is not needed. Ex. 1001, 6:15–20 (emphasis added).

“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

“We find that Holmberg expressly contemplates using its wall box within multi-dwelling units, notes that multi-dwelling wall boxes in the prior art were “typically provided” on every floor, and discloses that the multi-dwelling wall boxes would contain optical couplings for each resident on a given floor. Ex. 1004 ¶¶ 7, 34; Pet. Reply 8–10. In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices.

Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary. With access behind splice tray 230 required, Petitioner persuasively demonstrates that one of ordinary skill in the art would have seen a benefit to replacing Holmberg’s fasteners or screws with a hinged connection, such as that disclosed in Battey, to allow easier access to the area behind the splice tray. Pet. 41 (citing Ex. 1005 ¶ 39 (disclosing that a rotatable splice tray or shelf would “provide[] full and convenient access to the splice tray”)). First, Petitioner and Dr. Kiaei persuasively demonstrate that once the fibers of Holmberg are routed from behind splice tray 230 and the distribution cables spooled on this tray, a technician could not reasonably access fiber optic cables stored behind splice tray 230 without releasing or opening splice tray 230.
