      “ordinary skill in the art “would have had a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field with at least two years of experience developing software,” and “[a] person with less education but more relevant practical experience may also meet this standard.” Pet. 12 (citing Ex. 1002 ¶¶ 24–25). Flexiworld does not address the level of ordinary skill in the art in its Preliminary Response. Because Roku’s uncontested articulation of that level of skill is supported by testimonial evidence and appears reasonable at this stage in light of the subject matter of the ’114 patent, we adopt it for this decision. If Flexiworld contests this articulation at trial, we will consider any evidence that Flexiworld submits, in light of the full trial record.” slip op. at 16

      “dispute the construction of “one or more servers” and “one or more devices.” Pet. 11. But Roku argues that these constructions are irrelevant for this proceeding, and Roku “does not believe that any claim constructions are needed.” Id. Flexiworld also refers to this dispute in the Related Action, but does not propose explicit constructions for these or any other terms. See Prelim. Resp. 8 (citing Ex. 2010). We agree that the meaning of “one or more servers” and “one or more devices” is not pertinent to the outcome of our decision. To the extent any term needs construction, we address the term in the arguments below. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Although, Petitioner does submit that, “[f]or purposes of this IPR only, Petitioner relies on the claim scope positions Patent Owner has advanced in district court for ‘port definer module.’” Pet. 8. Similarly, Patent Owner argues each claim term should have its ordinary and customary meaning, except that, as in the parallel district court proceeding, the function of alleged means-plus-function term “port definer module” should be construed to be “designating any one physical link of the logical link and examining the designated link of the logical link.” Prelim.

      “argue that the reason to combine Ikonen and Gu is insufficient. Prelim. Resp. 47–52. However, Patent Owner’s argument misidentifies the proposed combination. While Patent Owner argues that there is no reason “why a POSA would have been motivated to substitute Ikonen’s Bluetooth solution with Gu’s (HTTP and TCP/IP based) UPnP networking framework,” the actual combination appears to be to implement Gu’s UPnP framework on Ikonen’s wireless LAN. Pet. 42 (“UPnP relies on IP networking . . . which a POSA would have known to be compatible with Ikonen’s wireless LAN option.”); Ex. 1002 ¶ 140 (Petitioner’s declarant explaining that UPnP could be implemented over a wireless LAN); see also Pet. 40–42 (the section entitled “Motivation to Combine” includes no explicit references to Ikonen’s teaching of Bluetooth, but rather only discusses Ikonen’s wireless LAN). All of Patent Owner’s arguments over the reason to combine focus on Ikonen’s teaching of Bluetooth, rather than Ikonen’s wireless LAN. See Prelim. Resp. 47–52. But, as we view the Petition to clearly set forth a reasonable rationale to combine Gu’s UPnP with Ikonen’s wireless LAN, and to provide evidence in support, Patent Owner’s arguments do not identify any shortcomings that undermine Petitioner’s showing at this stage. We do note that the Petition often refers to both of Ikonen’s teachings of Bluetooth and wireless LAN when discussing Ikonen individually. But, the Petition only refers to Ikonen’s teachings of wireless LAN when discussing the combination with Gu.” slip op. at 14

Accordingly, we determine that neither issues of time bar nor issues of estoppel are implicated. Under the Board’s precedential decision in Lumentum Holdings, Inc. v.

A lack of experience can be remedied with additional education (e.g., a Master’s degree), and likewise, a lack of education can be remedied with additional work experience (e.g., 4–5 years).

    • Strike new argumentNew argument consideredDecided for petitioner

      “We do not agree with Patent Owner that Petitioner’s so-called “third” theory is untimely and should be disregarded. To begin with, there is no dispute that the theory is, at least, raised with respect to claim limitation [1.8]. See PO Sur-Reply 6. Patent Owner disputes the particularity of this contention, but we find that it is sufficiently clear. The theory is not complicated and the sentence, especially given the detailed explanation of the other theories and of how Kalevo works, is sufficient to provide notice. Moreover, the cited paragraph of Dr. Freedman’s First Declaration (Paragraph 140) provides additional detail to clarify the theory. Ex. 1003 ¶ 140. Petitioner’s reply does explain how this third theory fits into Patent Owner’s arguments and claim constructions, but Petitioner’s Reply does not expand the theory beyond the contours provided in the Petition. As for limitations [1.9] and [1.10], we also find that the third theory was disclosed. To begin with the cited sentence in limitation [1.8] and supporting paragraph from Dr. Freedman’s declaration discusses the mapping of both directional and non-directional modes to classes, thus including both limitations [1.8] and [1.9]. As Petitioner points out, the Petition’s analysis of limitation [1.9] repeatedly refers back the analysis for limitation [1.8] and explicitly describes on page 52 of the Petition that Additionally, as a further teaching of this limitation, for the above case in which block L is classified as context class C3 (mapped to from directional class D4) and block U is classified as context class C4 (mapped from any one of directional classes D5, D6, or D7), the determination of each neighboring block’s classification, and thus, the determination of the intra prediction mode for the neighboring block, is based on a second set of one or more mathematical expressions. Pet. 52. Finally, with respect limitation [1.10], we note that, although it is less clear, the analysis of limitation [1.10] does explain how classes C1–C6 are not the same in that they involve different underlying rules. Id. at 55–57. Finally, Patent Owner’s arguments that “the Petition provided no analysis as to how the mapping constitutes a mathematical expression that is used in the process of determining the current block’s intra mode” is belied by the Petition’s detailed explanation of how Kalevo operates. See Pet. 16–25. Although Petitioner supports this argument with new evidence in its Reply, the Reply does not raise a new issue or argument. See Chamberlain Group, Inc. v. One World Techs., Inc., 944 F.3d 919, 925 (Fed. Cir. 2019) (“Parties are not barred from elaborating on their arguments on issues previously raised.”). Moreover, Patent Owner has had an adequate opportunity to address this new evidence in its Sur-Reply. See In re NuVasive, Inc., 841 F.3d 966, 972 (Fed. Cir. 2016) (finding “an opportunity to respond was needed when the petitioner . . . newly pointed to a previously unmentioned portion of the . . . prior-art patent, even though it had earlier focused extensively on other portions of that prior-art patent”).” slip op. at 24

      “In addition, we are not persuaded by Patent Owner’s argument that Stine1998 is not “salient to the Relevant Problems disclosed in the ’946 patent” because Stine1998 “relates to oxide CMP in a subtractive process,” which, according to Patent Owner, is directed to different problems, and different CMP than the metal CMP in a damascene process. PO Resp. 35. As Petitioner points out, Jaso, Stine1998, and the ’946 patent each address the “erosion of dielectric and dishing of metal” during CMP, which gives rise to “a non-planar surface.” Pet. 6 (citing Ex. 1001, 3:25–44, Fig. 4), 30– 31 (citing Ex. 1004, 2:7–19), 36–37 (citing Ex. 1004, 3:29–64; Ex. 1005, 668). Patent Owner’s assertion that different issues cause dishing and erosion too narrowly confines the problem that the references address. See Unwired Planet v. Google, 841 F.3d 995, 1001 (Fed. Cir. 2016) (“The field of endeavor of a patent is not limited to the specific point of novelty, the narrowest possible conception of the field, or the particular focus within a given field.”). Patent Owner also asserts “Jaso’s reference to ‘dishing’ is categorically different from the problems with which the ’946 patent is concerned: dishing of wide interconnect and erosion of oxide between dense narrow interconnect.” PO Resp. 63. We are not persuaded by this conclusory statement.10 Furthermore, to the extent Patent Owner argues the references are non-analogous art, all the references are directed to the creation of metal lines in chip manufacturing, as discussed above, and fall within the same field of endeavor.” slip op. at 31

      “Petitioner argues it would have been obvious to a person of ordinary skill in the art to combine Jaso and Stine1998 “to etch a plurality of dummy trenches in a dielectric layer between a first (wider) trench and a series of second (narrower) trenches.” Id. at 66 (citation omitted). Petitioner argues that a person of ordinary still in the art “would be motivated to combine the teachings in Jaso and Stine1998, as both references are directed to the addition of dummy conductors to equalize pattern density to improve CMP planarity.” Id. at 38–39 (citing Ex. 1004, code (57), 3:29–64; Ex. 1005, 668). In particular, Petitioner states that “Stine1998 enhances and improves upon the disclosure in Jaso by providing general teachings and specific methods that are widely applicable to dummy metal-fill techniques for addressing added capacitance.” Id. at 39 (citing Ex. 1005, 670–672). Petitioner points out that “Stine1998 expressly motivates a [person of ordinary skill in the art] to apply its teachings to a damascene process requiring dummy-fill to enhance planarity” because Stine1998 states its methodology can be extended to “inlaid metal techniques such as copper (emphasis omitted). Analysis of Patent Owner’s Arguments 1) Prior Art Does not “Look for” a Specific Configuration Patent Owner argues “Stine1998 does not tell the POSA to look for a specific configuration of structures, and then insert dummy metal into a particular location within that configuration (as the Relevant Solution does.)” PO Resp. 36–37. Patent Owner also argues that Jaso and Stine1998 “together accordingly tell the POSA to focus on pattern density, and to take steps to ensure that variations in pattern density across the chip are minimized” as opposed to looking for the particular configuration called out by the claims. Id. at 58. There is no requirement in the claims for the prior art to “look for” specific structures, but rather it must disclose those structure required by the claims.

      “look at Figure 8 and form any understanding of its structures at all” and thus, Dr. Boning’s opinions should be disregarded in their entirety. Id. at 44 (citing Ex. 2011 ¶¶ 191–199). We find that the explanations by Dr. Boning are a reasonable attempt to explain what one of ordinary skill in the art, with general background knowledge in the art, would glean from Figure 8 of Stine 1998 and are supported by additional cited references, such as Maly1991 and the StineThesis. See, e.g., Ex. 1052 ¶¶ 72 (citing Maly Fig. 4), 92 (citing Ex. 2016 (StineThesis), 92 (Ex. 2016, 165), 93. “[A] skilled artisan’s background knowledge is relevant to the reading of the prior art on which the obviousness challenge is based and . . . it is permissible, and sometimes even necessary, to establish such background knowledge by pointing to other prior art.” Rovalma, S.A. v. Bohler-Edelstahl GmbH & Co. KG, 856 F.3d 1019, 1027 (Fed. Cir. 2017). Despite Patent Owner’s criticism, Dr. Boning’s testimony cited by Patent Owner evidences Dr. Boning’s opinion that a person of ordinary skill in the art was aware of common artifacts and limitations in downscaled Boning also relies on secondary references to support his testimony about the general background knowledge of one of ordinary skill in the art. Ex. 1002 ¶¶ 65 (citing Ex. 1009 (Mead Textbook)), 74 (citing Ex. 1010 (Rabaey Textbook)), 75, 76, 152–157. Thus, we credit Dr. Boning’s testimony and do not disregard his testimony wholesale based on those alleged inconsistencies. Below, we focus on the testimony that is at issue in this IPR. There are three main reasons why Figure 8 of Stine1998 is at issue. First, Petitioner asserts that the white areas in Figure 8 are open areas between a wide trench and narrow trenches with no metal lines into which dummy conductors would be placed. See Pet. 37–38; Ex. 1002 ¶¶ 112, 152, 157. Patent Owner opposes that contention (PO Resp. 56) but, as explained in association with claim construction, we do not rely on a construction that requires no intervening trenches or other structures between the wide trench and narrow trenches. Additionally, Petitioner relies on the typical layout of chips and the figures of Jaso to support its interpretation of Figure 8. Pet. 45–46, 52–53. 13 Dr. Givens testifies that, because there is a discrepancy in Dr. Boning’s testimony regarding the inserts for various regions of Figure 8 of Stine1998 and the lack of any other inserts one of ordinary skill in the art would not assume the white areas contain no metal lines. Ex. 2011 ¶¶ 195–196. And, based on his magnification experiment, Dr. Givens testifies that Figure 4 of Maly1991 may contain metal lines. Id. We consider the fact that Dr. Givens’s testimony is largely based on what a person of ordinary skill in the art could discern from Figure 8 of Stine1998 and Figure 4 of Maly1991 alone rather than what one or ordinary skill in the art may glean based on their background knowledge in the art—for example whether Figure 8 of Stine1998 is consistent with conventional chip designs as Dr. Boning testified. Thus, we give slightly more weight to Dr. Boning’s testimony.” slip op. at 35

The fact that Jaso and Stine1998 may not purposefully seek out the configuration relied on by Patent Owner does not undermine Petitioner’s showing that the proper configuration would result from an obvious combination of the references. Thus, we are not persuaded by these arguments. Dummy Trenches We also disagree with Patent Owner’s argument that “Stine1998 does not teach or suggest any ‘trenches in a dielectric layer.’” PO Resp. 47, 55– 56. Patent Owner argues that Stine1998’s “subtractive process used for the manufacture of the disclosed chip does not involve the formation of such trenches.” Id. at 47 (citing Ex. 2011 ¶ 171). That is, Patent Owner asserts Stine1998 deposits a dielectric layer around already-formed metal lines. This argument, however, is not commensurate with the scope of the claims as properly construed. As noted above, to the extent that a damascene process is required, Jaso teaches such a process. Pet. 44. Additionally, assuming arguendo Patent Owner’s argument is correct, it stands to reason that the spaces where dielectric is not deposited are free of dielectric (due to the presence of metal lines) and, therefore, the “trenches” are free of dielectric. Patent Owner also asserts Stine1998 does not disclose dummy trenches because it “states in passing that certain areas of its test chip would be ‘prime candidates’ for ‘metal-fill,’ but does not actually disclose the particular location of any alleged ‘dummy’ conductor.” PO Resp. 56 (citation omitted) (citing Ex. 2011 ¶ 205). Patent Owner’s argument improperly attacks Stine1998 alone when Petitioner argues that the combination of Jaso and Stine1998 teaches “trenches.” See In re Keller, 642 F.2d 413, 426 (CCPA 1981). Petitioner points out that Jaso describes “a damascene method wherein, in general, a via or trench pattern is etched into a planar dielectric layer.” Pet. 44 (emphasis omitted) (citing Ex. 1004, 1:28– 31; 8:5–8; Ex. 1002 ¶¶ 142–144). Petitioner states that Figure 11B of Jaso includes “trenches (15a-d) [which] correspond to trenches for interconnects 45. Patent Owner does not address the trenches taught by Jaso, much less teachings of Jaso in combination with the teachings of Stine1998. See PO Resp. 33–36, 55–61. Accordingly, we are not persuaded that the combination of Jaso and Stine1998 fails to teach “trenches.”” slip op. at 29
