    “Analysis We agree with Petitioner. Mehta discloses storing “functionally equivalent programs having the same name that are capable of running on multiple kinds of devices that even may be written using different languages.” Ex. 1003 ¶ 98. Mr. Wechselberger testifies that this disclosure shows that Mehta’s “MAS receives, stores and supports functionally equivalent programs capable of running on multiple devices because each program corresponds to a different device having different device capabilities (e.g., written using different languages).” Ex. 1002 ¶ 66. This testimony is consistent with that of Dr. Goodrich, who testifies that “each application has a single version made for a particular device type.” Ex. 2020 ¶ 66. Dr. Goodrich later testifies that paragraph 98 of Mehta describes that there could be two functionally equivalent programs with the same name that are compatible with a single user’s computer. Id. at ¶ 88; see PO Resp. 31–32 (citing Ex. 2020 ¶¶ 87–88). We do not credit this later testimony, because it is inconsistent with Dr. Goodrich’s earlier testimony that “each application,” or program of Mehta, is “made for a particular device type.” Ex. 2020 ¶ 66. We agree with Mr. Wechselberger and find that a person of ordinary skill in the art at the time of invention would have understood that Mehta’s disclosure of functionally equivalent programs having the same name that are capable of running on multiple kinds of devices means that each program corresponds to a different device having different capabilities. Further, Mehta discloses that “the MAS only lists those applications that are supported by the subscriber’s device. This allows the subscriber to avoid the problem of having to explicitly select a compatible application.” Ex. 1003 ¶ 117; see Pet. 36–37 (citing Ex. 1002 ¶¶ 75, 77). Mr. Wechselberger testifies that a person of ordinary skill in the art at the time of invention would have understood this disclosure to mean that the MAS provides the subscriber with only a single subscriber-appropriate version that will work for the subscriber. Ex. 1002 ¶ 77. Although Patent Owner contends that Mehta is silent on whether only a single description would be provided if there were multiple implementations (PO Sur-Reply 10–11), we agree with Mr. Wechselberger and find that when multiple implementations have the same name, each implementation corresponds to a different device, and therefore, the MAS would only present to the subscriber the one implementation that works with the subscriber’s device.

    “piece of content, while the versions of Microsoft Word for Windows and Microsoft Word for Apple Macs are different implementations.” Ex. 2020 ¶ 39. Dr. Goodrich, in his deposition, when asked if “one of ordinary skill in the art at the time of the ’790 patent would also understand that Microsoft Word for Windows and Microsoft Word for Mac are also functionally equivalent, correct?” answered “Yes . . . . But they would be even stronger than simply functionally equivalent. They would be different implementations of the same product.” Ex. 1029, 43:14–24. However, later in his deposition, Dr. Goodrich testifies that Microsoft Word for Windows and Microsoft Word for Apple Mac are separate applications, not different implementations of the same application. Ex. 1029, 48:1–20. We disagree with this later testimony. Neither Dr. Goodrich nor Patent Owner persuasively explains why Dr. Goodrich changed his unambiguous position from both his declaration and his earlier deposition testimony. For example, Dr. Goodrich testifies in his deposition that “for the Lion King example, a .MP3 and a .MOV are different implementations of the same product. They’re also functionally equivalent, but functionally equivalent is broader.” Ex. 1029, 45:7–11. Dr. Goodrich continues, “when Mehta is disclosing functionally equivalent, it is not referring to it as different implementations of the same product. Instead, it’s [describing] how to disambiguate [applications] not clustered in terms of implementations . . . based on other metadata.” Id. at 45:14–21. This explanation is unpersuasive because it is inconsistent with Dr. Goodrich’s declaration testimony, in which Dr. Goodrich explicitly testifies that the different versions of Lion King, as well as the different versions of Microsoft Word, are different implementations of the same product. Ex. 2020 ¶ 39. Specifically, in his declaration, Dr. Goodrich testifies that the “various versions of Lion King (such as an .mp3 file or an .mov file) are the implementations of the Lion King. For another example, . . . the versions of Microsoft Word for Windows and Microsoft Word for Apple Macs are different implementations.” Ex. 2020 ¶ 39. Dr. Goodrich testifies again that “Microsoft Word for Windows and Microsoft Word for Apple Macs” are “multiple implementations of an individual item of digital content.” Ex. 2020 ¶ 70. Further, the reason given in the explanation in his deposition, that Mehta needs to disambiguate applications that are not clustered in terms of implementations based on other metadata, would also apply to the different versions of Lion King, yet Dr. Goodrich consistently testifies that these different versions are different implementations, both in his declaration and in his deposition. Id.; Ex. 1029, 45:7–10. Petitioner contends, and we agree, that the inconsistent testimony of Dr. Goodrich appears to be an attempt to cure Patent Owner’s and Dr. Goodrich’s incomplete analysis of Mehta’s disclosure. See Reply 7–8. In particular, the Petition quotes Mehta’s disclosure that the MAS stores “functionally equivalent programs having the same name that are capable of running on multiple kinds of devices that even may be written using different languages.” Pet. 28 (quoting Ex. 1003 ¶ 98). Dr. Goodrich addresses this disclosure by explaining that two applications, such as Microsoft Word and Apple Pages, are functionally equivalent but are two different applications, not multiple implementations of a single application. Ex. 2020 ¶ 70. In this analysis, Dr. Goodrich does not address the full disclosure of Mehta, which describes that the “functionally equivalent programs hav[e] the same name” (Ex. 1003 ¶ 98), such as Dr. Goodrich’s example of Microsoft Word for Windows and Microsoft Word for Apple Macs. See id. Thus, although Dr. Goodrich is correct in testifying that some functionally equivalent programs, such as Microsoft Word and Apple Pages, are not different implementations of an item of digital content, he is also correct in testifying that “Microsoft Word for Windows and Microsoft Word for Apple Macs” are “multiple implementations of an individual item of digital content.” Id. Yet Dr. Goodrich does not identify any difference between the multiple implementations of Microsoft Word and the functionally equivalent programs having the same name as described by Mehta.” slip op. at 18

    “is included in the indication. See PO Resp. 40. However, the ’559 patent does not describe what is included in the claimed “listing.” Rather, throughout the disclosure of the ’559 patent, the phrase “the listing of one or more pieces of content stored in memory” or a variation thereof is repeated without any further elaboration. Ex. 1001, 3:13–15, 3:26–36, 12:22–26, 12:50–52, 13:29–30. For example, the Specification does not disclose that the listing of one piece of content includes the title of the piece of content, nor an identification number of the piece of content, nor any other information about the piece of content. The disclosed listing is no more than an item of information that indicates that a specific piece of content is stored in the memory of the terminal. Therefore, the plain and ordinary meaning of the claim term “a listing of one . . . piece[] of content stored in the memory,” read in light of the Specification of the ’559 patent, encompasses an item of information that indicates that a specific piece of content is stored in the memory of the terminal. We agree with Petitioner and find that Cassin’s indication that the client currently has the media content item describes an item of information that indicates that a piece of content is stored in the memory of the terminal. Therefore, Cassin’s indication that the client currently has the media item describes “a listing of one . . . piece[] of content stored in the memory” as claimed.” slip op. at 33

Reply 11 (citing Pet. 25–26), 13–14. Cassin discloses that the server uses the user information received from the client to query a database in the server for a list of content to which the user is entitled. Ex. 1004 ¶¶ 162, 164. Cassin discloses that the server offers an item from the list to the client for downloading. Id. ¶ 163 (The server offers every item on the list), ¶ 164 (The server attempts to send an item on the list). Cassin discloses that the client checks to see if it already has the item. Id. ¶¶ 163, 164. If the client has the item, the client refuses the download offer. Id. If the client does not have the item, the client accepts the download of the item and stores the item in its content repository. Id. Thus, the client responds to the offer to download an item from the server by (a) checking to see if it has the offered item, and (b) either refusing the download if the client has the item or accepting the download if the client does not have the item. Therefore, we agree with Petitioner and find that “when the server offers a media item for the client to download, the server is ‘instructing the terminal to perform one or more actions to thereby control the flow of content.’” Reply 11 (citing Pet. 25–26). We agree with Petitioner that in response to the server’s offer, “the client will either ‘refuse the download’ (if it has the content) or ‘accepts the download of the media content item from the server and stores the media content in the local content repository’ (if the client does not have the content).” Id. (citing Ex. 1004 ¶ 163). We agree with Petitioner and find that by checking to see if it has the item, and “by refusing or accepting the download offer, the client is doing ‘something to control the flow of content’ in response to the server’s instruction.” Id. (quoting PO Resp. 23). We disagree with Patent Owner’s contentions to the contrary. In particular, we disagree with Patent Owner’s contention that the server’s offer “has not instructed the client to do anything—the client takes action based on other factors (whether or not it already has the media content item).” PO Sur-Reply 3; see PO Resp. 31–32; Ex. 2002 ¶¶ 91–93. We find that the client performs the actions of checking to see if it already has the item and, depending on whether it has the item, either accepting or refusing the offer, in response to receiving the offer from the server. Ex. 1004 ¶¶ 163, 164; Ex. 1003 ¶¶ 72–75. Thus, we agree with Petitioner that the server’s offer instructs the client to (a) determine whether the client has the item and (b) depending on whether the client has the item, either accept or refuse the offer, which describes “instructing the terminal to perform one or more actions to thereby control the flow of content” as claimed. We further find that, because the offered item is from the server’s list which was determined using information from the user and information from the server’s database, the offer to download the item describes “a response to the content status . . . based upon the terminal status information and the server status information” as recited in claim 1.” slip op. at 26

    “algorithm on Chen’s plurality of clusters of processors, the Petition contends that Jiang alone teaches limitations 1(d) and 1(e) in disclosing assigning an initial score to each of the initial nodes of a prefix tree, then using these initial scores to determine, via pruning, whether to continue processing branches connected to the nodes. Pet. 38 (citing Ex. 1004, 8–64); see id. at 31–44. We agree with Patent Owner that the Petition does not explain how Jiang’s pruning would be implemented in Chen’s multiple clusters of processors to generate an initial score for an audio sample, and to use the initial score “to determine whether to continue processing” as required by limitations 1(d) and 1(e). In contending that Jiang alone teaches limitations 1(d) and 1(e), the Petition quotes from Jiang’s description of its pruning technique: scores assigned to that node with the largest score on any of the other nodes corresponding to the frame being considered. If the score at a particular node is sufficiently low compared to the maximum score for other corresponding nodes in tree 77, it is assumed that the branches leading to the node under consideration (the node with the lower score) will not likely be part of the completed most likely phoneme sequence (i.e., the phonemes in that sequence will not likely be part of the final word recognized by the system). Thus, that branch is dropped (or pruned) from tree 77 and is no longer considered in further processing. Pet. 38–39 (quoting Ex. 1004, 8:52–64) (emphasis in original). Petitioner concludes that “[p]er Mr. Schmandt, Jiang thus teaches an initial score . . . used to determine whether to continue processing to determine a final score . . . . Dec., 90–91. As such, Jiang teaches claim 1(e).” Pet. 43–44. The Petition explains how Jiang’s pruning algorithm generates an initial score and uses the initial score to prune, or “determine whether to continue processing” as recited in claim 1, but does not explain how Jiang’s pruning algorithm would be implemented on Chen’s four clusters of processors shown in Figure 4, as required by the Petition. That is, the Petition does not explain how each of the processors in the four clusters of Chen, after generating a score for one of the initial nodes, would compare the score with the maximum score of all corresponding initial nodes in tree 77. In fact, the Petition, in relying on Jiang alone to teach this limitation, does not even contend that Jiang’s pruning technique would be performed by any of Chen’s clusters of processors, let alone explain how pruning would have been performed by Chen’s parallel processing computer system.” slip op. at 20

    “We disagree with Petitioner’s contention that to perform speech recognition, the processors in each cluster would not need to access the memories of the other clusters. See Reply 26. Petitioner’s contention is inconsistent with Petitioner’s contention that “[o]nce the cumulative probability score is calculated, inter-cluster processing of the results for each tree search would be communicated.” Reply 4; see id. at 16. Petitioner’s contention is inconsistent with the intrinsic evidence, which discloses that parallel implementation of a search algorithm for speech recognition requires a significant amount of communication and synchronization. Ex. 1001, 1:47–52. Petitioner’s contention is inconsistent with Mr. Schmandt’s testimony that if we’re going to be doing pruning based on thresholds, then we have to know the scores that we got on each of the trees, so I think that’s a safe assumption, that that’s in there. So when each of the processors has performed its task on its set of trees, it can produce a set of numbers, and looking at the numbers across all of the processors, across all of the results, we can choose a pruning threshold just like Jiang chooses a pruning threshold after it performs all these operations in serial as opposed to parallel. inconsistent with Jiang’s teaching that pruning is performed by comparing a score at a particular node to the maximum score for other corresponding nodes in the prefix tree. Ex. 1004, 8:55–64. We rely on Dr. Anderson’s testimony, that a parallel implementation of Jiang’s algorithm “requires extensive communication between computational components” and that “all four memories 104(a)-(d) would contain necessary information” to perform limitations 1(d) and 1(e), in finding that performing Jiang’s algorithm using Chen’s clusters of processors would have required the processors to access data in all of the cluster memories 104a-d in order to determine the scores of the corresponding nodes of the tree. Ex. 2020 ¶¶ 29, 51. We disagree with Petitioner’s contention that performing Jiang’s algorithm using the processors of Chen would have resulted in the benefit of an increase in speed. Pet. 10. We credit Dr. Anderson’s testimony that Mr. Schmandt’s assumptions that the clustered processor and memory arrangement of Chen would have necessarily improved the speed and power of Jiang’s speech recognition are incorrect. Ex. 2020 ¶¶ 35 (citing Ex. 1003 ¶¶ 67, 74), 36 (citing Ex. 2021, 11). Petitioner contends that Dr. Anderson’s testimony is conclusory and that Patent Owner does not provide evidence other than Mathew I to support its contention that the combination would have a high synchronization overhead. Reply 20–21. We disagree, and find that Dr. Anderson’s testimony is sufficiently supported by evidence, including Jiang, Chen, and Mr. Schmandt’s Declaration. For example, Dr. Anderson testifies that the Viterbi algorithm compares most likely outcomes from the previous frame. Ex. 2020 ¶ 29 (citing Ex. 1004, 1:19–39, 2:1–26). Dr. Anderson testifies that to perform these comparisons requires extensive communication between computational components that can have a drastic impact on system performance. Id. ¶¶ 29, 43. Dr. Anderson testifies that as a result, performing Viterbi decoding when the information needed may be in a cluster that is not directly accessible, as in Chen, is not likely to be successful in a practical speech recognition system. Id. (citing Ex. 1003 ¶ 95; Ex. 1005, 9:10–39); see id. ¶ 43. Thus, Dr. Anderson further supports his testimony with citations to Jiang, Chen, and Mr. Schmandt’s Declaration. In addition, Mr. Schmandt does not support with objective evidence his testimony that using Chen’s clusters of processors would have increased the computing power for implementing Jiang’s speech recognition techniques to desirably result in improved processing speed and power. See Ex. 1003 ¶¶ 67, 74. Although Mr. Schmandt mentions Hon (Ex. 1006), Tremblay (Ex. 1027), Erman (Ex. 1025), Wulf (Ex. 1024), Garde (Ex. 1028), and Deo (Ex. 1026) in his testimony, Mr. Schmandt does not persuasively explain how these background references would have taught a person of ordinary skill in the art that Chen’s parallel processing computer system, which includes an extended shared memory model and a distributed memory model, would have increased the speed of Jiang’s speech recognition algorithm over Jiang’s shared memory model.” slip op. at 31

    “We agree with Patent Owner. Petitioner has not shown that any of the integrated circuits cited in the Petition would have been able to include the claimed acoustic model memory. Further, we find, contrary to Petitioner’s contention, that Patent Owner did not admit that procuring a processor and a memory capable of storing an acoustic model memory fabricated on an integrated circuit was within the level of ordinary skill. To the contrary, throughout the entire proceeding, Patent Owner has consistently argued that the claimed “calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” was unknown in the prior art. Petitioner has not shown that using the prior art elements relied on in the Petition according to their established functions would have resulted in “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1. In summary, Petitioner relies on Mozer to teach the benefits of fabricating a calculating apparatus and an acoustic model memory on the same integrated circuit, but Mozer does not teach a calculating apparatus and an acoustic model memory fabricated on the same integrated circuit. Further, the benefits of Mozer identified by Petitioner are benefits that both Mozer and Smyth already have, without fabricating the calculating apparatus and the acoustic model memory on the same integrated circuit. Also, even if Petitioner had shown there was a reason to combine Smyth and Mozer, Petitioner does not persuasively show that the combination teaches “the calculating apparatus and the acoustic model memory are fabricated on a single integrated circuit” as recited in claim 1. The Petition identifies only model memory for storing an acoustic model defining a plurality of acoustic states” as claimed, which is the one that “a POSITA would have been motivated . . . to fabricate” (Pet. 44), which was beyond the level of ordinary skill. We find that the Petition has not shown that claim 1 is unpatentable over Smyth and Mozer.” slip op. at 38

    “In our Decision to Institute, we understood Petitioner’s theory based on the combination of Smyth and Mozer to include fabricating an integrated circuit in stating that we were sufficiently persuaded “that fabricating a single integrated circuit that includes a calculating apparatus and an acoustic model memory . . . was within the level of ordinary skill.” Dec. 23. Our understanding was based on the Petition’s multiple contentions that a person of ordinary skill would have found it obvious to fabricate Smyth’s processor and state memory on a single integrated circuit. See Pet. 41–44. For example, the Petition contends that “[a] POSITA would have found it obvious . . . to fabricate [Smyth’s processor and state memory] on a single integrated circuit” (Pet. 41–42 (emphasis added)); “a POSITA would have understood and found obvious . . . to fabricate a calculating apparatus and acoustic model memory on a single integrated circuit” (Pet. 42 (emphasis added)); “[s]uch a use of a known technique of fabricating a memory and processor on a single integrated circuit” (id.

However, as discussed in the previous paragraph, when discussing the combination of a processor and an acoustic model memory on an integrated circuit, the Petition used the verb “to fabricate” four times in the future tense and once in the present tense, as well as the verb “to form” once in the future tense. The Petition did not use the past tense phrase “were already fabricated” as alleged in the Reply. Moreover, the Petition did not map Smyth’s state memory (which the Petition contends teaches the claimed “acoustic model memory” (see Pet. 11)) to a memory already fabricated on an integrated circuit in the prior art. Rather, the Petition relied on Mozer to support its contention that a person of ordinary skill would have fabricated the calculating apparatus and acoustic model memory of Smyth on an integrated circuit. See Pet. 42, 44. The Petition cited Boike and Ozcelik in contending that fabricating an integrated circuit with processors and memories was well known, and cited Toyoda in contending that fabricating an integrated circuit with a calculating apparatus and an acoustic model memory was well known. Pet. 43–44 (citing Ex. 1006; Ex. 1029; Ex. 1034). However, the Petition did not explain how a memory located in one of the integrated circuits of Mozer, Boike, Ozcelik, or Toyoda would have been able to store Smyth’s state memory. Therefore, we disagree with Petitioner’s contention that “the Petition did not map a POSITA physically fabricating an IC, but rather mapped a single IC on which a calculating apparatus and acoustic model memory were already fabricated.” Reply 23–24.

    “(1) Apple’s Proposed Combination According to Apple, Brown teaches that processing stages in a speech-recognition system may be pipelined such that “as the frames of data are generated, the data is processed from one stage to another so that the operations are synchronized with the rate of frame generation.” Pet. 44–45 (citing Ex. 1036, 3:32–48; Ex. 1003 ¶¶ 206–209). Apple contends that a person of ordinary skill in the art would have had reason to modify the combination of Jiang and Baumgartner by pipelining data sent from the CPU to the SLA and then back to the CPU because “[p]ipelining data offered numerous well-known advantages including greater throughput of the processor, improved performance, decreased cost, and simplified programming.” Pet. 45 (citing Ex. 1003 ¶ 210). Apple also argues that a person of ordinary skill in the art “would have realized pipelining keeps all processors operating efficiently in a multi-processor system, such that wasteful idle-processing time is minimized.” Pet. 46 (citing Ex. 1003 ¶¶ 212–213). And according to Apple, “Jiang already discusses the importance of time with respect to pruning.” Pet. 46 (citing Ex. 1004, 10:65– 11:25). Apple also argues that a person of ordinary skill in the art would have had a reasonable expectation of success in adding Brown’s pipelining to the Jiang–Baumgartner combination because “[p]ipelining was well-known in the art including in speech recognition systems,” and the three references “teach speech recognition systems using similar hardware, such as various processors to perform similar speech recognition functions,” such that the combination “would have been a trivial modification.” Pet. 46–47 (citing Ex. 1004, 4:60–65, 6:32–36, 6:39–42; Ex. 1007 ¶ 33, Fig. 19; Ex. 1036, 3:11– 15; Ex. 1003 ¶ 214).” slip op. at 21

    “We find Apple’s arguments persuasive that pruning is not required as part of its proposed combination of Jiang, Baumgartner, and Brown. Nothing in Jiang suggests that pruning is mandatory—it is presented as option, possibly a preferred option, but not a requirement. See Ex. 1004, 8:52 (“[A] pruning technique can be used.” (emphasis added)). Although Apple relied on the possibility of pruning in Jiang as part of the motivation to combine Jiang’s system with Baumgartner’s parallel-processing hardware, Apple never included pruning as an element needed to meet any limitation of claim 1. See Pet. 41, 46; Ex. 1003 ¶¶ 194, 201, 213. Although Jiang teaches the desirability of using pruning, at least “for a large vocabulary” (Ex. 1004, 2:19), there is nothing in claim 1 limiting how small the acoustic model can be. Also, whether or not a person of ordinary skill in the art could have achieved real-time speech-recognition system without pruning is not pertinent to achieving the claimed invention because claim 1 does not require real-time speech recognition. Apple has persuasively shown that a person of ordinary skill in the art would have had reason to implement Jiang’s system on parallel-processing hardware, as Baumgartner teaches, using pipelining as Brown teaches to meet all the limitations of claim 1, even without Jiang’s pruning embodiment, and that this combination would have been within the ordinary skill in the art.” slip op. at 23

    “We find Apple’s arguments persuasive notwithstanding Zentian’s arguments to the contrary. We credit Mr. Schmandt’s testimony that consolidating the overlapping data within similar lexical models (such as “sports” models like football or baseball) and storing the consolidated data in a shared memory that multiple processors may access in parallel would have resulted in memory and processing efficiency. Ex. 1003 ¶¶ 83–84. This would have been an improvement over Thelen, where each processor has access to only one, distinct lexical model at a time and there is no shared memory in which multiple processors can access the same consolidated models data in parallel. See Ex. 1030, 7:30–34.11” slip op. at 27

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Because a person of ordinary skill in the art is a hypothetical person, we agree with Apple that Dr. Anderson’s inability to implement a particular computer vision application within the constraints of a particular Texas Instruments parallel-processing environment does not mean that more general knowledge and skill in parallel processing would have been beyond the level of ordinary skill. To the contrary, the evidence of record suggests that a person of ordinary skill in the art at the time of the claimed invention, who, for example, had a master’s degree and two years of experience in the field of speech recognition, would have also had knowledge and experience with parallel processing.” slip op. at 9

    “Apple states that it “applies the plain and ordinary meaning of all claim terms,” and does not propose any explicit constructions. See Pet. 7. Likewise, Zentian does not propose any explicit constructions. See PO Resp. We do not find it necessary to explicitly construe any terms for this decision. To the extent that we need to interpret claim language, we address that language below in the context of the prior art. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’ . . . .” (quoting Vivid Techs., Inc. v. Am.

    “would not have been dissuaded from the memory-efficiency benefits of modifying Thelen–Bailey by grouping processors and memory into clusters because memory collisions would have allegedly made recognition slower. Although memory collisions may have been an issue for the ordinarily skilled artisan to consider, Apple has persuasively shown that there are other motivating considerations, such as the known flexibility12 and scalability of distributed processing systems in general, decreased cost because off-the-shelf components may be used, and the added efficiency of data sharing among related sub-context models. See Pet. 40–45. Apple persuasively shows, and we find Mr. Schmandt’s supporting testimony credible, that a skilled artisan would have expected to be able to minimize the effect of memory collisions based on Chen’s teachings and the background knowledge in the art. See Pet. 14–19. For the same reasons, we do not find credible Dr. Anderson’s testimony (see, e.g., Ex. 2020 ¶¶ 44–46)” slip op. at 28
