“In its Response, InterDigital does not contest Dr. Acampora’s articulation of the level of ordinary skill, except that “InterDigital applies Petitioners’ alleged baseline level of ordinary skill without the phrase ‘at least.’” PO Resp. 3. We agree with InterDigital that the term at least arguably “creates unnecessary ambiguity.” Id. (citing Inst. Dec. 9–10). But we find that Petitioner’s articulation, after deleting the phrase at least, is reasonable in light of the subject matter involved in the ’449 patent, and we adopt it for our decision.” slip op. at 10

“To the extent that text was copied and pasted in either direction between the Petition and Dr. Acampora’s declaration, we disagree that this mere fact indicates that we should give Dr. Acampora’s testimony less weight. Patent Owner does not argue that Dr. Acampora was uninvolved with the preparation of his declaration, which he signed, under penalty of perjury, and presented as reflecting his own opinions. That typographical errors may, for example, have been propagated from his declaration to the Petition is by itself of little consequence. The cited Wowza decision does not suggest otherwise. In that case, the Board assigned little weight to the expert declaration, not because of its similarity to the petition, but because the declaration did not disclose the underlying facts or data on which its opinion testimony was based. See IPR2013-00054, Paper 16 at 4–5. As Petitioner correctly argues in its Reply, InterDigital does not “identif[y] where Dr. Acampora fails to provide sufficient facts underlying his opinions.” Pet.

“1. “channel quality” InterDigital states that the court in the parallel district court litigation adopted the parties’ agreed construction of “channel quality” as meaning “a value/values quantifying how efficiently downlink resources of a channel can communicate information.” PO Resp. 3–4 (citing Ex. 2008, 1; Ex. 2009, 18). InterDigital contends that the ’449 patent suggests this construction, and that both sides’ experts agree with it.

“Although Patent Owner contends Dr. Goodnick’s declaration did not open the door for general questioning about metal oxides (PO Opp. 2–3), we agree with Petitioner that the proper scope of cross examination includes Dr. Goodnick’s understanding of what constitutes a distinct layer. A primary issue raised by Patent Owner against Petitioner’s challenge that Goodnick anticipates is that, notwithstanding its use of the term layer, Goodnick does not teach distinct layers that are required by the claim. See Section VI.B. One of those layers is a metal oxide layer (Ex. 1101, claim 1), in particular a titanium oxide layer (claim 6). In view of Dr. Goodnick’s checkerboard analogy in his declaration, it was proper for Petitioner to question Dr. Goodnick about the extent of materials in the checkerboard. Both parties argue there may be implications of Dr. Goodnick’s testimony for purposes of infringement litigation. See Pet. Opp. 4–6; PO Reply 3–4. We do not address those implications. The issue before us is whether Goodnick would have taught or suggested to a person of ordinary skill the limitations of the claims, which the parties agree include distinct layers of metal oxide and other semiconductor oxide. See Section VI.B. As Dr. Goodnick testified that his article did not teach such distinct layers, it was proper for Petitioner to explore Dr. Goodnick’s views concerning the composition of a layer during cross examination. In consideration of the above, Patent Owner’s motion to exclude the Goodnick Metal Oxide testimony is denied.” slip op. at 48

“that “the semiconductor region comprises an n-typed doped source or drain of a transistor.” Acknowledging that Goodnick “does not expressly disclose that its n-doped silicon semiconductor region ‘comprises an n-type source or drain of a transistor,’” Petitioner cites Jammy as disclosing this feature. Pet. 27. According to Petitioner, a person of ordinary skill would have combined the teachings of Goodnick and Jammy because Goodnick describes contact metallization processes for semiconductor devices and Jammy describes a semiconductor device. Id. at 28. Patent Owner asserts that Petitioner’s challenge to claim 4 based on the combined teachings of Goodnick and Jammy fails because it is premised on Goodnick teaching a stratified layer of Al2O3 distinct from SiO2. PO Resp. 60. As discussed above, we find that a person of ordinary skill would have understood Goodnick to disclose this feature. See Section VI.B. In consideration of the above, we find that Petitioner has demonstrated by a preponderance of the evidence that a person of ordinary skill would have had reason to combine the teachings of Goodnick and Jammy and that the combined teachings of Goodnick and Jammy would have suggested the limitations of claim 4 to a person of ordinary skill in the art.” slip op. at 24

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

“b. Analysis We adopt Petitioner’s proposed construction for advertising break: “a break in the program content (the ‘Internet radio stream’) where advertising content was or can be inserted.” Reply 2. The Specification and challenged claims support Petitioner’s proposed construction. First, both parties agree that an advertising break is a type of program break. PO Resp. 14; Reply 2. Although the Specification does not expressly define the term “program break,” the Specification uses the term to refer to a break during which content which is distinct from a program was or can be inserted. For example, the Specification discloses that audio programs in an Internet radio stream “will normally include program breaks during which audio content that is distinct from the program content is delivered.” Ex. 1001, 1:34–36 (emphasis added). The Specification further describes that the “present invention seamlessly selects content for outputting on a mobile device during a program break in an Internet radio stream using mobile device location information and program break markers.” Id. at 1:64–67 (emphasis added). The Specification has additional disclosures of selecting non-program content for insertion in a program break.

“ii. Analysis We agree with Petitioner that an ordinarily skilled artisan would have been motivated to combine Rittmaster’s and Duvall’s teachings, would have had a reasonable expectation of success in making that combination, and would not, as Patent Owner argued, have had to substantially reconstruct and redesign Rittmaster to do so. We credit Mr. Wechselberger’s testimony that an ordinarily skilled artisan would have been motivated to combine the teachings of Rittmaster and Duvall with a reasonable expectation of success. Ex. 1011 ¶¶ 46–50. As Mr. Wechselberger explains, Duvall provides the details of how to select an advertisement from the stored advertisements using a duration indicator combined with other factors, such as location. Ex. 1011 ¶¶ 46, 50; Ex. 1008, 8–9, 24. Because Rittmaster’s similar system also selects advertisements based on the user’s location and other criteria to provide advertisements that fit the programming break, an ordinarily skilled artisan would have expected Duvall’s teachings to work in Rittmaster’s system. Ex. 1011 ¶ 50; Ex. 1007 ¶ 132. Duvall provides further details on how to select content that fits the programming breaks, as suggested by Rittmaster. Ex. 1011 ¶¶ 46, 50; Ex. 1008, 8–9, 24. Duvall discloses how to add or implement a variable duration indicator to a system for providing targeted content to users, like the system of Rittmaster. Ex. 1011 ¶¶ 46, 50; Ex. 1008, 8–9, 24. And an ordinarily skilled artisan would have had a reasonable expectation of success in applying Duvall’s teachings to Rittmaster’s system because Duvall uses local storage of the advertising options in its client-side system in a manner similar to the storage of advertisements in the server-side system of Rittmaster.

We do not credit Dr. Rhyne’s testimony that combining the teachings of Rittmaster and Duvall would have required a substantial redesign of Rittmaster. Ex. 2002 ¶¶ 90–92.11 Regarding this issue, Dr. Rhyne testifies: 11 In paragraph 90, Dr. Rhyne refers to the substantial reconstruction of Estese, but the reference to Estese appears to be a typographical error. This section of his declaration addresses the combination of Rittmaster and Duvall. Rittmaster would require fundamental reconstruction to incorporate Duvall’s content identification list information 122 because Duvall’s content identification list information 122 only identifies advertisement data already embedded in a data stream. Rittmaster teaches using time frames during which content such as an advertisement may be inserted. See Rittmaster at [0132]; Ex. 2001 at 33, lines 20–24. Like Estese, Rittmaster is a system where time frames or windows allow customization by interleaving location-based advertisements into the frame before delivering it to the recipient. Rittmaster at [0132]. To use Duvall’s content identification list information 122, which identifies advertisement spots that are already part of a media stream, would thus require replacing the frame structure of Rittmaster with a full media stream that could then be overwritten—or in the terminology of Duvall, “muted”—in specific locations when told to by content identification list information 122.” slip op. at 34

“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
