    “Patent Owner argues that the ’105 patent claims were “fully supported as of the filing date of at least the ’606 Application . . .

PO Resp. 63–65; PO Sur-reply 26–29. Patent Owner’s argument is persuasive. The ’606 Application discloses: [W]hen the toilet fill valve 100 is open and water flows from the water inlet 103 to the water outlets 106 and into a toilet tank, an amount of water is also supplied to the bowl fill valve inlet 113 that flows through the bowl fill valve 109 and out the bowl fill valve outlet 116. By virtue of the manual setting of handle 119 of the bowl fill valve 109, the flow of water through the bowl fill valve 109 is regulated. In this manner, the flow of water is regulated so that enough water flows out of the bowl fill valve 109 to fill a toilet bowl without wasting any water down a drain. seen from the passage above, the ’606 Application discloses regulating an amount of water supplied to a toilet bowl using a valve (i.e., a water flow regulator). Ex. 2013 ¶ 288. Further, the ’606 Application states: The bowl fill valve 109 may be, for example, a ball valve, a gate valve, a globe valve, a plug valve, a diaphragm valve, a butterfly valve, a needle valve, a sliding gate, a quick turn valve, a knife valve or any other appropriate type of valve as can be appreciated by those with ordinary skill in the art.” slip op. at 42

The disclosure need only reasonably convey to a POSA that the inventor had possession of the subject matter in question, even if every nuance of the claims is not explicitly described in the specification.

Analysis of Claims 1–18 Schuster is available as prior art if the ’993 patent is only entitled to its January 27, 2014, filing date and not entitled to claim priority to earlier filing dates of the parent applications. On its face, the ’993 patent claims priority to a number of earlier parent applications, including Application No. 12/786,904 (the ’904 Application) filed May 25, 2010, and the Application code 63. Petitioner contends that the ’993 patent is not entitled to claim priority to the filing date of the earlier parent applications, and, thus, Schuster, a parent application of the ’993 patent, is available as prior art.15 Pet. 91–92. Petitioner alleges that the earlier parent applications, specifically Application No. 12/786,904 (the ’904 Application), do not provide written description support for the ’993 patent’s claim term “water flow regulator.” According to Petitioner, “water flow regulator” encompasses both adjustable devices for restricting the flow of water (i.e., valves) and fixed devices for restricting the flow of water (i.e., restrictors). Pet. 15. Petitioner contends that the ’904 Application does not provide support for water flow restrictors and, thus, does not provide support for the broader claim term water flow regulators. Id. at 14–15, 91–92. Petitioner argues that only adjustable water flow devices (i.e., valves) are supported by the ’904 Application. Id.

    “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.

    “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

    “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

    “’026 patent would have had a Master’s degree in Electrical Engineering or Computer Engineering, plus at least two years of experience in integrated circuit design, or alternatively a Bachelor’s degree in one of those fields plus at least four years of experience in integrated circuit design. Pet. 16 (citing Ex. 1102 ¶ 49). In our Institution Decision, we found Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the prior art of record, see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Neither Patent Owner, in its Response, nor Dr. Annavaram, in his declaration, proposes a level of ordinary skill in the art. Instead, Patent Owner states that “Patent Owner applies Petitioner’s stated skill level for this response” (PO Resp. 26), and Dr. Annavaram similarly states that “[f]or the purpose of this declaration, I adopt Dr. Harris’ definition of a [person of ordinary skill in the art]” (Ex. 2009 ¶ 24). Nothing in the full record persuades us that our preliminary finding as to the level of ordinary skill in the art was incorrect. Based on the complete record, because our preliminary finding is consistent with the level of ordinary skill in the art reflected by the prior art of record, we maintain and reaffirm that one of ordinary skill in the art at the time of the invention would have had a Master’s degree in Electrical Engineering or Computer Engineering, plus at least two years of experience in integrated circuit design, or alternatively a Bachelor’s degree in one of those fields plus at least four years of experience in integrated circuit design.

    “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
