While the wherein clause describing the dimensions of “said granule” relies on “granule” in the preamble for antecedent basis, none of the other preamble language appears to be necessary to breathe life and meaning into the claim, and the claim body recites a structurally complete invention.

    “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].

    “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

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.

    “We find that Dr. Dayan’s testimony on these points lacks sufficient supporting analysis. In opining that the tested substituents are representative of the steric and electrostatic properties across the claimed substituents, Dr. Dayan merely compares the properties of the tested substituents to each other. See, e.g., id. ¶¶ 52–56. He does not expressly compare them to the properties of the many remaining, untested substituents within the scope of the claims. See id.; see also Reply 14 (“At best, [Dr.] Dayan testified that the positive activity . . . at each substituent” suggests that the position is involved in herbicidal activity, “not that the tested compounds were sufficient to provide any reasonable expectation of success as to the billions of structurally diverse compounds covered” by the claims.). And although Dr. Dayan acknowledges that several tested compounds showed no herbicidal activity, he does not expressly explain how he took these compounds into account in nevertheless concluding that an ordinarily skilled artisan would expect at least some activity across all claimed substituents. See, e.g., Ex. 2011 ¶¶ 54–56 (noting exceptions to herbicidal activity). As one example, Dr. Dayan acknowledges the lack of activity shown in the data for substituents larger than hydrogen at the R6 position, but does not explain the impact of that data on the remaining claimed substituents. See id. ¶ 54 (Dr. Dayan noting that activity is “not as favored by larger alkyl groups” at R6, but nevertheless concluding that “one would expect at least some herbicidal activity” across all claimed R6 substituents). In contrast, Dr. Hunt compares the size and properties of the R6 substituents that showed no activity with the size and properties of other claimed but untested R6 substituents. Ex. 1003 ¶¶ 163, 166–68; Ex. 1029 ¶¶ 37, 38. This comparison indicates that the majority of R6 substituents are larger than the tested substituents, such that the vast majority of the claimed compounds (i.e., those with compounds having R6 substituents larger than those tested), could have no herbicidal activity. Ex. 1003 ¶ 167; Ex. 1029 ¶¶ 12, 37, 38. Thus, we find that the data in the Specification regarding at least position R6 gives a person of ordinary skill in the art reason to doubt that substantially all compounds within the full scope of claim 1 of the ’202 patent would exhibit herbicidal activity. Ex. 1003 ¶ 163; Ex. 1029 ¶¶ 11, 12, 38; In re Surrey, 370 F.2d 349, 355 (CCPA 1966) (“[W]here the applicant seeks to obtain a monopoly in exchange for his disclosure of a group of compounds there should be a disclosure which gives a reasonable assurance that all, or substantially all of them are useful.”).” slip op. at 29

Conclusion In sum, it is undisputed that claim 1 covers at least a billion compounds. The art is unpredictable, and the Specification indicates that not all of the compounds falling within claim 1 are effective herbicides. See, e.g., Pet. 22 (listing compounds that showed no herbicidal activity). Although the level of ordinary skill in the art is relatively high and the field is mature, Petitioner establishes by a preponderance of the evidence that the ’202 patent does not provide sufficient meaningful guidance or working examples across the full scope of claim 1 to allow a person of ordinary skill in the art to determine which other compounds across the full scope of the claim have herbicidal activity without undue experimentation.” slip op. at 45

    “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

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
