      “Petitioner contends that a person of ordinary skill in the art at the time of the alleged invention would have had “a Bachelor of Science degree in computer science and two years of industry experience or research working with database and related storage management technologies,” and that “[a]dditional education, such as an M.S. in computer science, could substitute for the industry experience.” Pet. 9 (citing Ex. 1003 ¶ 30). According to Petitioner, the person of ordinary skill would have been familiar with “DRAM cache, flash or other solid-state storage device[s], tape, optical media, and other well-known storage types,” “[c]oncepts of data ‘temperature,’” “[m]ulti-level storage tiers and managing data storage between volatile devices (e.g., cache) and non-volatile devices (e.g., disk) based on temperature,” and “[w]ell-known concepts such as volatile storage, non-volatile storage, and data persistency.” Id. at 9–10 (citing Ex. 1005, 2:23–38, 5:65–6:3, 21:33–43, 25:21–62; Ex. 1010 ¶¶ 3–4; Ex. 1004 ¶¶ 18– 52; Ex. 1001, 8:7–13).

      “sufficiently established that Morris inherently discloses this element based on the evidence of record. Petitioner does not point to specific portions of Morris that expressly state that storage information associated with storage of data in the disk drive (such as temperature values 420 in Figure 4) are provided to the cache, or that indicate that this step is necessarily present in Morris’s system. For example, it appears that there might be other places for storing temperature information or other ways of providing that information to the cache. Additionally, Dr. Long does not explain why one of ordinary skill would have “necessarily” understood that Morris’s process would have checked data HEADER 410 in Figure 4 to see if it contained a temperature value, and then used this temperature value as part of the Figure 2 steps, rather than obtaining the temperature value from another source. However, we determine that, for purposes of institution, Petitioner has sufficiently shown that element 1.3 would have been obvious over Morris. Petitioner’s obvious argument is supported by Dr. Long’s testimony that, when using data temperature to determine whether data should be stored in the cache (as reflected in Figure 2), it would have been obvious to “check[] the data ‘HEADER’ (410 in FIG. 4) to see if it contained a ‘temperature value’ (420 in FIG. 4), and then us[e] this temperature value as part of the FIG. 2 steps.” Ex. 1003 ¶ 51. As Dr. Long explains, data objects 400 with headers 410 and temperature values 420 in Figure 4 are “stored on a disk drive.” Id. ¶ 46. Dr. Long further testifies that one of ordinary skill “would have recognized the expressly disclosed ‘temperature value’ variable” 420 stored on the disk “as the best measure of a given data object’s temperature and the first place to check for whether a disk-stored data object had an associated temperature.” Id. “Given the express disclosure of this [temperature value] variable” 420, Dr. Long continues, it “would have been a natural choice” for the person of ordinary skill in the art to use it “when evaluating whether to cache data being read from the disk,” and one of ordinary skill would have had a reasonable expectation of success in doing so. Id. Contrary to Patent Owner’s argument, this testimony provides logical reasons why one of ordinary skill would have provided the temperature value from the disk to the cache, and is not merely “conclusory.” We reach a similar determination as to Petitioner’s obviousness argument based on the process for determining whether data should be deleted from the cache in Morris’s Figure 3. Petitioner’s argument is supported by Morris’s statement that “[t]he data temperature is stored with the data object in the cache,” and Dr. Long’s testimony that it would have been obvious to have “this data temperature in the cache originate[] from the ‘temperature value’ retrieved from the disk when originally storing the data in the cache.” Ex. 1004 ¶ 53; Ex. 1003 ¶ 54. Dr. Long further explains that “it would have been obvious to implement the Morris system in this way because the temperature maintained on the disk was the most natural source for the value of the data temperature stored in the cache,” and one of ordinary skill “would have used that approach with a reasonable expectation of success.” Ex. 1003 ¶ 54. “In fact,” according to Dr. Long, “given that the temperature value was persistently stored with the data on the disk,” the disk “was the only logical source for a reliable temperature value when deciding whether to load the data into the cache,” because “[a]ny other source would have risked being inaccurate or out of date and would have needlessly and redundantly stored the temperature in another location.” Id. This testimony provides logical reasons why one of ordinary skill would have provided the temperature value on the disk to the cache.” slip op. at 17

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “Based on the present record, we do not find Patent Owner’s proposed construction supported by the intrinsic evidence. The ordinary meaning of “manage the storage of data in the volatile storage” does not require limiting the number of copies of the data in the volatile storage, and Patent Owner does not argue to the contrary. Turning to the language of the other claims, we note that claim 5, which depends from claim 1, specifically includes additional language stating that the data is stored “only in one of two portions of the volatile storage,” but claim 1 does not include such language. The use of this additional limitation in dependent claim 5 suggests that the inventors did not intend it to be included within claim 1’s broader language reciting “manag[ing] the storage of data in the volatile storage.” See Phillips v. AWH Corp., 415 F.3d 1303, 1315–16 (Fed. Cir. 2005) (en banc) (“the presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim”). Turning to the ’923 patent specification, the portions of the specification Patent Owner relies on appear to discuss a preferred embodiment of the invention, rather than limiting the invention itself. The portions of columns 14 and 15 upon which Patent Owner relies discuss Figure 3 which, the specification explains, “depicts a volatile storage 300 that uses a persistent temperature-based storage management technique as well as a conventional storage management technique in accordance with one embodiment.” Ex. 1001, 14:48–51 (emphasis added); see id. at 5:5–8 (also describing Figure 3 as being “in accordance with one embodiment” of the invention). Interpreting claim 1 to require maintaining only a single copy of a data portion in either the first portion or second portion, where that language does not exist in claim 1, would be tantamount to reading a limitation from a preferred embodiment into the claims, which would be improper. See Philips, 415 F.3d at 1323 (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments.”). Patent Owner does not identify any portions of the specification suggesting that limiting the number of copies of the data in the volatile storage is a necessary part of the invention, or that the inventors intended to expressly or impliedly define “manage the storage of data in the volatile storage” to include this requirement. Consequently, at this stage of the proceeding, we do not adopt Patent Owner’s proposed construction requiring that “manag[ing] the storage of data in the volatile storage” requires “coordinating placement of data into and out of the volatile storage so as to limit the number of copies of the data in the volatile storage.” The parties may further address the meaning of this claim phrase during the trial, if appropriate.” slip op. at 10

      “Petitioner contends that a person of ordinary skill in the art at the time of the alleged invention would have had “a Bachelor of Science degree in computer science and two years of industry experience or research working 2 At this stage of the proceeding, Patent Owner has not presented objective evidence of non-obviousness. with database and related storage management technologies,” and that “[a]dditional education, such as an M.S. in computer science, could substitute for the industry experience as it typically involves at least two years of additional study focused exclusively on computer science, as well as a thesis or project spanning several terms to implement a substantial project.” Pet. 12–13 (citing Ex. 1003 ¶ 31). According to Petitioner, the person of ordinary skill would have “understood the advantages of partitioning a volatile memory into multiple different sections (e.g., buffer pools) and applying multiple different storage management (e.g., cache replacement) policies to those different sections, and known how to implement such designs.” Id. at 13 (citing Ex. 1003 ¶ 32). Patent Owner does not dispute Petitioner’s proposed level of ordinary skill at this stage of the proceeding. Prelim. Resp. 14. For purposes of institution, we adopt Petitioner’s assessment of the level of ordinary skill in the art, which is consistent with the ’923 patent and the asserted prior art of record.” slip op. at 13

    • Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Instituted

      “At this stage of the proceeding, Petitioner has made a sufficient showing that Lee discloses this claim element. Paragraph 17 of Lee discloses the use of a temperature-based storage management technique and a non-temperature-based storage management technique (the LRU replacement policy), and that both “may be used to manage a cache.” Ex. 1004 ¶ 17. Based on the present record, Petitioner sufficiently shows that Lee’s disclosure of using these techniques “to manage a cache” involves “manag[ing] the storage of data in” the cache, because both techniques operate in order to control what data is stored in the cache. We do not find Patent Owner’s argument persuasive because it is based on Patent Owner’s proposed construction of “manag[ing] the storage of data in the volatile storage” to require “limit[ing] the number of copies of the data in the volatile storage,” which we do not adopt. See § II.A.2, supra. Consequently, we determine that, on the record before us, Petitioner’s cited evidence sufficiently supports its contentions regarding this limitation.” slip op. at 17

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “In our Institution Decision, we found that Petitioner’s proposal was consistent with the level of ordinary skill in the art reflected by the prior art of record and we preliminarily adopted Petitioner’s unopposed position. Inst. Dec. 8–9 (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978)). As neither party challenges our preliminary finding regarding the level of ordinary skill in the art, we see no reason to disturb that finding. Accordingly, we maintain and reaffirm that one of ordinary skill in the art at the time of the invention would have had “a bachelor’s degree in mechanical engineering, electrical engineering, computer science, or a similar field with at least two years of experience in adaptive streaming and content management” or “a master’s degree in mechanical engineering, electrical engineering, computer science, or a similar field with a specialization in adaptive streaming or content management” and that “[a] person with less education but more relevant practical experience may also meet this standard.” See Inst.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

      “the case law makes clear that “an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising’” unless an “extremely limited” exception applies. See Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016) (quoting KCJ Corp., 223 F.3d at 1356; Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342 (Fed. Cir. 2008)). Here, claim 1 recites the transitional phrase “comprising,” meaning it is open-ended, and, therefore, the usual meaning of “a” as “one or more” would have been expected absent an extremely limited exception. In considering whether an exception applies, our review of the ’515 patent fails to indicate that the patentee intended the phrase to mean anything other than the usual meaning of “one or more.” Patent Owner asserts that “[t]he plain language of the claim clearly indicates only a single [list] is used to list multiple assets” and quotes two portions of the Specification, which state “a list of assets that satisfies criteria” and “a list of assets to which a . . . device is granted access.” PO Sur-reply 12–13 (quoting Ex. 1001, 12:60–67) (citing Ex. 1001, 2:23–34, 3:1–5, 4:21–23, 17:59–66). Although claim 1 of the ’515 patent recites “assets” in the plural, we fail to see how that conveys that the term “a” would have been understood as limited to “one.” Notably, neither party has identified any inconsistency, in the claims or other portions of the Specification (including the portions quoted and/or cited by Patent Owner), resulting from construing “a” as “one or more.” And, we find that there is no reason why the claims could not be met under the construction of “a” as “one or more.” Thus, we find that the ’515 patent does not “evince [ ] a clear intent to limit a or an to one.” See Convolve, 812 F.3d at 1321 (internal quotations omitted). Accordingly, we construe the term “a” in “a list of assets” as “one or more” such that the phrase “a list of assets” means “one or more list of assets.” Considering next the phrase “the list of assets” recited in limitation 1[e], the parties do not dispute that the use of the term “the” means that “the list of assets” refers back to the one or more list of assets retrieved in limitation 1[d] and discussed above. See PO Resp. 1–2; see generally Pet. Reply; PO Sur-reply 5. Similarly, the parties do not dispute that the phrase “the filtered list of assets,” recited in limitation 1[e], refers back to the list of assets resulting from the filtering step of limitation 1[d]. See PO Resp. 3–4; see generally Pet. Reply; PO Sur-reply 5. We agree with the parties that each of these phrases refers back to the previous instance of the recited terms.” slip op. at 15

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundUnpatentable

      “motivated to combine these teachings for several reasons. Pet. 21. First, Petitioner contends “the combination is the use of a known technique to improve similar devices because using the capabilities of a client device to choose appropriately formatted content was a well-known technique.” Id. Petitioner asserts that “implementing Marusi’s techniques for organizing multiple representations and choosing among them based upon a client device’s capabilities would predictably function in Pyle’s system, which similarly seeks to target video content based on particular client device types and parameters.” Id. (citing Ex. 1004, 10:57–11:10; Ex. 1003 ¶ 147). Second, Petitioner argues that “detecting a client device’s capabilities based upon client device identifiers was a common and known solution to the problem of supplying information in a format usable by the client device.” Pet. 21. Petitioner contends that one of ordinary skill in the art “would have found it obvious to combine Marusi’s teachings with Pyle because it is one solution, from a finite number of known, and predictable solutions.” Id. (citing Ex. 1003 ¶ 148). Third, with respect to Marusi’s databases, Petitioner contends “[t]he combination of Marusi’s databases to manage the data in Pyle’s system uses a known technique to improve similar systems.” Pet. 21. In particular, Petitioner asserts that one of ordinary skill “would have been motivated to combine Marusi’s database teachings with Pyle because Pyle teaches storing the same content in multiple, different representations.” Id. at 21–22 (citing Ex. 1004, 9:64–10:21). Further, Petitioner argues that “[u]sing a database to store and manage multiple representations of the same data, or even to simply store voluminous data for retrieval, was an extremely well-known and common application of databases.” Id. at 22 (citing Ex. 1003 ¶ 149). Additionally, Dr. Reader opines that one of ordinary skill in the art “would have understood that the teachings of Pyle and Marusi were complementary, and therefore would have been motivated to combine Pyle with Marusi to enhance the efficiency of generating, storing, and delivering multimedia content tailored to the capabilities of particular playback devices.” Ex. 1003 ¶ 150.” slip op. at 27

      “Patent Owner that Petitioner and Dr. Reader fail to explain why one of ordinary skill in the art would have understood that Pyle generates a top level index file by placing a manifest file in memory for transmission to a client device. Pet. 35; see Ex. 1003 ¶ 184. “Opinions expressed without disclosing the underlying facts or data may be given little or no weight.” Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019) (“Consolidated TPG”), 40–41, available at https://www.uspto.gov/sites/default/files/documents/tpgnov.pdf (citing Rohm & Haas Co. v. Brotech Corp., 127 F.3d 1089, 1092 (Fed. Cir. 1997)). Here, there is no explanation or reason given for Petitioner’s assertion or Dr. Reader’s testimony and the connection, if any, is not otherwise apparent. Further, aside from Dr. Reader’s unexplained position, Petitioner has not pointed us to any evidence of record supporting the argument that one of ordinary skill in the art would have understood that placement of a file in memory for transmission teaches generating the file as recited in limitation 1[f]. Accordingly, without any explanation whatsoever, the record is without a sufficiently supported basis upon which to make that finding, resulting in a failure of proof by Petitioner with respect to claim 1.11 10 We also note that Petitioner’s Reply does not seek to add a new argument for our consideration; rather, Petitioner’s Reply asserts, albeit incorrectly, that the argument was raised in the Petition. See Pet. Reply 15. 11 Although Petitioner’s Reply sets forth several arguments in response to other arguments raised in Patent Owner’s Response, those additional arguments do not address to this aspect of limitation 1[f]. See, e.g., Pet. c. Dependent Claims 4, 5, 8–10, and 14 Petitioner contends that the combination of Pyle and Marusi would have rendered the subject matter of claims 4, 5, 8–10, and 14 obvious to one of ordinary skill in the art. Pet. 36–41. Claims 4, 5, 8–10, and 14 depend from claim 1 and, therefore, include limitation 1[f], as discussed above. Accordingly, for the same reasons discussed with respect to claim 1, Petitioner’s analysis of these claims suffers from the same deficiency.” slip op. at 34

Neither Patent Owner, in its Response, nor Dr. Annavaram, in his declaration, proposes a level of ordinary skill in the art.

      “To the extent Patent Owner argues that these particularized selection clauses recited in different claims must have the same or similar meaning because they all use the word “selecting” (see PO Resp. 28–29), we disagree with Patent Owner. See IGT v. Bally Gaming Int’l, Inc., 659 F.3d 1109, 1117 (Fed. Cir. 2011) (“We caution that claim language must be construed in the context of the claim in which it appears. Extracting a single word from a claim divorced from the surrounding limitations can lead construction astray. Claim language must be construed in the claim in which it appears.” (emphasis added)). The selection clauses recited in these claims are plainly different on the face of the claims when considering the material differences in the claim language set forth above. According the same meaning to the limitations that recite “select . . . based on” indicators, “select . . . when” certain conditions are met, and “select . . . out of a group” of values would be improper because it would blur the material differences in the claim language recited expressly in the claims. Instead, we interpret the selection clauses recited in the challenged claims “in the context of the particular claim in which the disputed term appears” and “in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. In other words, we do not construe the single word “selecting” in isolation, but, rather, interpret the full selection clauses recited in the challenged claims in the context of the entire patent. Claim 13 recites “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator.” In our view, the plain meaning of this limitation is clear on the face of the claim—a value of a control signal is selected based on two indicators, the mode indicator and the leakage indicator.” slip op. at 14

      “Tr. 47:7–23. Because the output of Kim’s NAND gates will be different depending on the value of Kim’s memory cells C1–CN allowed to “pass through,” we agree with Petitioner that the value of Kim’s memory cells C1– CN (the claimed “leakage indicator”) “plays a role” in deciding what the output of Kim’s NAND gates (the claimed “value of the control signal”) will be. Moreover, Patent Owner acknowledged that the output of Kim’s NAND gate is determined based on the inputs to the NAND gates (i.e., the sleep signal input and the memory cell signal input). JUDGE CHUNG: But, knowing a little bit about how a NAND gate works, isn’t it the case that the input to the NAND gates, G1 through GN, with the input of the sleep signal and the C1 through CN signal, isn’t it the case that input to the NAND gate determines what the output is? MS. ZHONG: Okay. So any logic gate, the output will depend on the input. That’s for sure. Tr. 44:18–25; but see id. at 45:3–10 (stating that even if the “output is in control of the input, . . . that does not mean the selection is based on that input”). Thus, we find that Kim’s NAND gate (the claimed “control circuit”) operates to determine its output (the claimed “value of the control signal”) based on its input of the sleep signal (the claimed “mode indicator”) and the memory cell value input (the claimed “leakage indicator”). As discussed in Section III.B, the Specification indicates that “select[ing] the value of the control signal based on the mode indicator and on the leakage indicator” recited in claim 13 is synonymous to determining the value based on the recited indicators. See Ex. 1101, 4:4–11. Thus, the evidence of record shows that Kim teaches “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator,” as recited in claim 13.” slip op. at 44

      “We are not persuaded by Petitioner’s argument and evidence. First, although Petitioner proposes “[s]ubstituting Lee’s inputs of leakage current and temperature for generating a power gate control signal” (i.e., Lee’s “control signal (BIAS)”) for “Kim’s inputs of leakage current and other ‘stimuli’ for generating a power gate control signal” (Pet. 64 (citing Ex. 1102 ¶ 115)), neither Petitioner nor Dr. Harris explains adequately how they are proposing to “substitute” Kim’s control signal with Lee’s “control signal (BIAS).” For example, Figure A reproduced above does not show how Petitioner or Dr. Harris proposes to use Lee’s “control signal (BIAS)” in the proposed combination. Petitioner asserts that “[a]lthough Lee’s control signal is analog and Kim’s control signal is digital, it was well known to apply teachings in an analog domain to a digital domain, and conversions between analog and digital domains were easy to implement.” Pet. 66 (emphases added) (citing Ex. 1102 ¶ 121; Ex. 1115). Dr. Harris similarly states that Figures A and B show examples of obvious ways to use in Kim’s system Lee’s teaching of setting conductance of the array based on temperature. A POSA would have found both of these ways obvious. That Lee uses an analog control signal and Kim uses a digital control signal would have presented no obstacle to a POSA. . . . That is, converting analog circuit elements and signals to digital was well known long before the ’026 patent. Ex. 1102 ¶ 121 (emphases added) (citing (Ex. 1115) (“Analog-to-digital converters (ADC’s) are ubiquitous, critical components of software radio and other signal processing systems.”)). But Dr. Harris does not explain adequately how “to use in Kim’s system” the digitized BIAS signal of Lee. See id. The only additional input signal shown in Figure A compared to Figure 4 of Kim is the temperature line that has the value of 0 when the temperature is cold and the value of 1 when the temperature is hot. See Ex. 1102 ¶ 116 (Fig. A). There is no explanation of how the modified teaching of the BIAS signal of Lee (i.e., modified or converted to a digital signal) would have worked in the proposed combination of Figure A.” slip op. at 69
