      “Level of Ordinary Skill in the Art Citing testimony from Dr. Houh, Petitioner contends a person of ordinary skill in the art “would have had at least a B.S. degree in computer science or electrical engineering (or comparable degree) and two years of experience in networking or streaming media, or a M.S. in computer science or electrical engineering (or comparable degree).” Pet. 12 (citing Ex. 1003 ¶ 45). Patent Owner does not address the level of ordinary skill in the art in its post-institution papers. We adopt Petitioner’s definition of the level of ordinary skill in the art. On the present record, we are satisfied that this definition of the level of skill is consistent with the teachings of the ’234 patent and the asserted prior art.” slip op. at 11

      “On this record, we determine that the recitation “to achieve continuous presentation” is limiting and requires an amount of continuous (uninterrupted) playback/presentation after an upshift or downshift. The specification describes agent controller 702 determining whether to upshift based on a trigger threshold Θup, which itself is based on various factors including a current read ahead margin and a minimum safety margin. See Ex. 1001, 17:44–58. If agent controller 702 can sustain upshift quality, then it will upshift and request higher quality streams. See id. at 17:58–61. Conversely, when an upshift is not possible, agent controller 702 determines whether to downshift based a different threshold Θdown, which itself is based on the same sort of factors. See id. at 18:4–7. When the stream quality is not adequate, it downshifts. See id. at 18:7–14. These disclosures are similar to the language of claim 12, which recites “repeatedly generating a factor indicative of a current ability to receive the digital content at a rate sufficient for presenting the digital content as the digital content is received, . . . wherein the factor relates to a performance of the network” and “making the successive determinations whether to change the requested bit rate based on the factor to achieve continuous presentation of the digital content using the individually-requestable portions of the highest bit rate one of the copies determined receivable at that time.” Ex. 1001, 20:5–16 (emphasis added). That is, claim 12 refers to “achiev[ing] continuous presentation” based on what is “sufficient for presenting the digital content,” trading quality to ensure continuous playback.” slip op. at 14

      “server comprises at least two servers and wherein at least one streamlet is requested from a first of the at least one server and at least one other streamlet is requested from a second server of the at least one server other than the first server.” Ex. 1001, 19:7–12. Petitioner references its mapping of the “at least one server” in claim 1 to Leaning’s server 1. Pet. 20 (citing Ex. 1004, 2:15–16, 2:18–22, 2:31–32, 5:8–14, Fig. 1), 23 (citing Ex. 1004, 6:13–26, 9:3–7, 16:6–12), 37; see supra §§ II.D.2.b–c. Petitioner contends that, “[t]o the extent Leaning does not disclose at least two servers wherein one sub-file (streamlet) is requested from a first server and another sub-file (streamlet) is requested from a second server such an arrangement would have been obvious in view of the knowledge of a [an ordinarily skilled artisan].” Id. at 37. Citing the common nature of such an arrangement, Petitioner contends that an ordinarily skilled artisan would have been motivated to provide multiple web servers containing the same sets of sub-files for streams in order to have redundancy in the system and allow for clients to establish connections with multiple servers and request a first sub-file from a first web server and, if the connection between the first web server becomes congested or the first web server otherwise fails or becomes unavailable, request a subsequent sub-file from the second web server. Id. at 37–38 (citing Ex. 1003 ¶ 85; Ex. 1012, 108,5 Fig. 4-11). Patent Owner does not dispute Petitioner’s analysis for claim 3. We are persuaded that it would have been obvious to implement Leaning’s server 1 as two servers that store different streamlets based on Dr. Houh’s uncontested testimony about system redundancy. See Ex. 1003 ¶ 85. His testimony is backed by a contemporaneous reference about HTTP that shows requests for different objects from different servers over parallel TCP connections. See, e.g., Ex. 1012, 108–09, Fig. 4-11. Thus, we determine that Petitioner has shown, by a preponderance of the evidence, that the subject matter of claim 3 would have been obvious over Leaning.” slip op. at 34

    • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

      “specification is the ‘single best guide to the meaning of a disputed term,’ . . . and ‘is, thus, the primary basis for construing the claims.’” Trs. of Columbia Univ. in City of New York v. Symantec Corp., 811 F.3d 1359, 1362 (Fed. Cir. 2016) (citations omitted). Although Patent Owner contends that the Specification disparages systems that impose significant restrictions on the possible choices of frequencies (PO Resp. 21), we find availing Petitioner’s contention that “[s]upport for Patent Owner’s construction is absent from the specification.” Pet. Reply 10. As Petitioner points out, Patent Owner’s claim construction “appears to be based on a single paragraph of the ’443 patent referring to preexisting ‘synchronization schemes [that] restrict the phase relationship and relative frequencies of the clocks.” Id. That is, the only reference by Patent Owner to the Specification is that the Specification states that “Some synchronization schemes restrict the . . . relative frequencies of the clocks, thereby eliminating the need for hardware arbitration [27]. Unfortunately, these schemes impose significant restrictions on the possible choices of frequences.” PO Resp. 26 (citing Ex. 1001, 6:32–36). We agree with Petitioner that such disclosure in the Specification “does not describe how these synchronization schemes ‘restrict the phase relationship and relative frequencies’ with any specificity.’” Pet. the Specification that some schemes impose restrictions on the possible choices of frequency is not a disparagement of any system that has limited choices of frequency or would preclude the claims from covering such prior art techniques. Instead, as Petitioner points out, the Specification of the ’443 patent states “[t]he preferred embodiment uses four domains […] so that domains may vary somewhat in size and still be covered by a single clock.” Id. (citing Ex. 1001, 5:57–59). As Dr. Baker testified in support of Petitioner’s contention, “the preferred embodiment of the ’443 patent relies on a single external master clock that distributes a signal to the local PLL of each domain.” See Ex. 1032 ¶ 9. Thus, although Patent Owner contends that clock signals generated based on a master clock cannot be interpreted to be generated independently of the clock signals generated for others of the plurality of domains (PO Resp. 49), we agree with Petitioner that such claim construction would “exclude[] the preferred embodiment of the ’443 patent,” which is disfavored. Pet. Reply 11. For the reasons discussed above, we conclude that “changeable independently” of the other domains does not require that the separate clocks in the plurality of domains be globally-asynchronous.” slip op. at 12

      “As both parties recognize, (PO Resp. 5; Pet. Reply 12), “[actual] [r]eduction to practice in the United States requires that the invention be embodied in tangible form.” Scott v. Koyama, 281 F.3d 1243, 1247 (Fed. Cir. 2002). In particular, actual reduction to practice requires a showing of the invention in a physical or tangible form that shows every element. not sufficient. See Kimberly-Clark v. Johnson & Johnson, 745 F.2d 1437, 1445 (Fed. Cir. 1984). Here, Patent Owner does not provide any evidence showing every element of the claims in physical or tangible form, as required, but rather contends that the Specification refers to the Paper, wherein the Paper stated that simulation using a software, SimpleScalar, was performed. PO Resp. 16. We are persuaded by Petitioner’s contention that the SimpleScalar simulation was not an actual reduction to practice of the claimed invention. Pet. Reply 12. As Petitioner points out, claim 1, for example, is directed to a “microprocessor,” wherein “Patent Owner has presented no evidence and has not alleged that any physical microprocessor was ever produced or operated.” Id. at 13; see PO Resp. 15–17. And as Petitioner points out, “Patent Owner has produced no evidence of any physical prototype of the claimed microprocessor that could have validated the simulation.” Pet. Reply 13–14. We agree with Petitioner that, at most, such simulation “demonstrated feasibility for prototyping of a microprocessor,” but not a tangible form of the microprocessor itself as required for an actual reduction to practice. Id. at 14; see also Standard Mfg. Co. v. United States, 25 Cl. Ct. 1, 67 (1991) (“The feasibility of the optical alignment system may have been proven by the optical mock-up, but the optical mock-up was not a reduction to practice of the proposed MHU–145/M trailer.”).” slip op. at 36

      “Here, we find that Petitioner has not met its burden to prove that one of ordinary skill in the art would have recognized that “the functional units of Georgiou operate asynchronously since they have different clocks.” Pet. 74 (citing Ex. 1002 ¶¶ 53–56, 211–219). Specifically, although Petitioner relies on Georgiou for teaching different clocks, Petitioner’s conclusory statement that such application would operate asynchronously requires gapfilling. Id. As Patent Owner points out, Georgiou discloses a clocking architecture in which “all domain clocks are derived from a shared master clock through predetermined rational dividers.” PO Resp. 49. Petitioner concedes during the oral hearing that, in systems such as Georgiou, each domain clock is set a fraction of a master clock, and thus, the various domain clocks are “possibly” synchronous with each other. Tr. 59:4–14 (JUDGE DANG: . . . would being fractions of the master, wouldn’t they be synchronized with each other? MR UHR: They may be, . . . the answer is possibly.”) Thus, we find Petitioner’s contention that a POSITA would have recognized that the functional units of Georgiou operate “asynchronously” lacks sufficient support in the record. We find the testimony of Dr. Baker insufficient to support Petitioner’s position. Ex. 1002 ¶¶ 53–56, 213, 215–219. In his declaration, Dr. Baker testified that he “provided several references . . . that explain operating domains asynchronous to one another while the domains operate synchronously.” Id. ¶¶ 215–219. However, although such references explain “globally asynchronous, local synchronous (GALS) systems” (id. ¶ 216), Dr. Baker does not explain why a POSITA “would have known that a functional unit of Georgiou also operates asynchronous with respect to at different frequencies.” Id. ¶ 217. Without evidentiary support, we are left with speculation and impermissible hindsight. See in Re Wagner, 379 F.2d 1011, 1017 (CCPA 1967). We decline to engage in speculation. See, e.g., In re Vaidyanathan, 381 F. App’x 985, 993 (Fed. Cir. 2010); In re Wallen, 565 F. App’x 867, 869 (Fed. Cir. 2014), both citing In re Zurko, 258 F.3d 1379, 1386 (Fed. Circ. 2001) ([T]he Board must point to some concrete evidence in the record in support of these findings.”). In sum, based on our review of the record, we find Petitioner’s showing is insufficient. Thus, based on the complete record presented, we determine that Petitioner has not persuasively shown that Georgiou teaches “operating the microprocessor such that each domain operates synchronously, while the domains operate asynchronously relative to one another,” as recited in claim 8.” slip op. at 28

      “The plain language in claim 1 of “auxiliary electrode” does not preclude that the “electrode” may be a power line, bus line, or resistor. Ex. 1001, 8:47–52. Nothing in the Specification clearly precludes “auxiliary electrode” from being a “bus line” or “power line,” as Patent Owner proposes. PO Resp. 25–27. We are unpersuaded by Patent Owner’s contention that the Specification discloses that “the power line ‘PL’ is shown in Figure 1, but the power line PL is not an electrode that is shown in Figure 2.” Id. at 26–27. Here, Patent Owner points to no portions in the Specification that provide the requisite “reasonable clarity, deliberateness, and precision” to warrant interpreting the claim language at issue as supporting Patent Owner’s contention that an auxiliary electrode cannot be a power line, bus line, or resistor. Id.; In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1984). That is, although Patent Owner points to Figures 1 and 2 of the Specification for support of its contention, Figures 1 and 2 of the Specification merely show various examples of power line and an auxiliary electrode.

      “We find Patent Owner’s arguments unavailing. In particular, we find unavailing Patent Owner’s contention that “‘bus line 430’ is not an ‘auxiliary electrode’” (PO Resp. 28–33), because Patent Owner is relying on a claim construction of “auxiliary electrode” as precluding “essential” elements and requiring “more than the end structure of a conductor” (id.), that is not adopted by our construction discussed above. Here, we are persuaded by Petitioner’s reliance on Weaver’s bus line 430 for providing the claimed “electrode,” that is “supplemental to other electrodes in the structure.” Pet. 18; see also Ex. 1004 ¶ 26, Fig. 4; Ex. 1003 ¶ 92. We find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that a POSITA would have understood that “anode 406 and bus line 430 are connected in parallel,” which means that “bus line 430 is a supplemental electrode that reduces the total resistance of the pixel structure.” Pet. 19; Ex. 1003 ¶ 94.

Reply 17–18 (citing Ex 1003 ¶ 157; Ex. 1020 ¶ 45). Further, contrary to Patent Owner’s contention that POSITA would not have combined Weaver with Lee ’053, Song, Lee ’149, or Bae without the use of hindsight (PO Resp. 33–45), as Petitioner points out, Lee ’149, for example, “explicitly teaches that ‘the electrode pattern 45 serves to lower the resistance of the first electrode 41.” Pet. Reply 58 (citing Ex. 1011 ¶ 38). Similarly, Bae “explicitly teaches that the “auxiliary electrodes 139 contact the first electrode 132 to commonly apply a voltage to the sub-pixels” and “reduces the resistance of the first electrode.” Id. at 66 (citing Ex. 1012 ¶¶ 37, 59). As such, Petitioner’s proposed combinations are supported by at least by Lee ’149’s and Bae’s teachings of applying a second electrode to lower the resistance and voltage drop between anode 406 and the VDD line of Weaver.

We are persuaded by Dr. Baker’s testimony that a POSITA would have understood that higher resistance between the power or ground line to the light emitting device would consume more power and require higher operating voltages, and thus, would have been motivated to implement the solutions of Lee ’053, Song, Lee ’149, or Bae to lower the resistance between anode 406 and voltage source VDD in Weaver. Ex. 1003 ¶¶ 145, 158, 184, 203.

ORDER For the reasons given, it is ORDERED that pursuant to 35 U.S.C. § 314, an inter partes review is instituted as to claims 1, 2, 5–8, 11, and 12 of the ’803 patent to determine whether: 1) claims 1, 5–7, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over TS 36.300, TS 36.321, and TS 36.331; 2) claims 1, 2, 5–8, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson and TS 25.331; and 3) claims 5, 6, 11, and 12 are unpatentable under 35 U.S.C. § 103 as obvious over Ericsson, TS 25.331, and Sebire; and” slip op. at 27

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

      “ordinary meaning, “primary” and “non-primary” cells are all cells that the WTRU is connected to (PO Resp. 16), the plain language in claim 1, and similarly in claim 7, does not require a “primary” node or “non-primary” cell to have a connection to the WTRU. See Ex. 1001, 10:38−56; 11:11–26. We find unavailing Patent Owner’s contention that the claims require that the WTRU “be connected to more than one cell,” wherein cells that are “associated with a wireless network node,” but are not connected to the WTRU “at the same time” cannot be “primary” or “non-primary” cells. PO Resp. 16. In the ’803 patent, nothing in the Specification clearly limits “primary” and “non-primary” cells as Patent Owner proposes. Prelim. Resp. 16. Patent Owner points to the Specification of the ’803 patent to show that, for softer handover, the WTRU is connected “with more than one cell [] which are controlled by the same Node-B,” and “[o]ne of the[se] cells 808 may be designated as a primary cell 808a, while other cells are designated as a non-primary cells 808b.” Id. (alterations in original) (citing Ex. 1001, 8:44–46, 9:4–6, Figs. 8A–B). However, this portion of the Specification (describing a softer handover embodiment in which a cell “may be designated” as a primary while other as non-primary) does not provide a clear definition to warrant interpreting the “primary” and “non-primary” cells as requiring “connection” to the WTRU “at the same time.” Id. That is, nothing in the Specification clearly precludes “primary” and “non-primary” cells from being “source” and “target” cell, as Patent Owner contends. PO Resp. 16. and the Specification, we determine that the terms “primary” and “non-primary” recited in claims 1 and 7 are not limited to cells connected to a WRTU at the same time. We determine no further explicit construction of this term is necessary to resolve the controversy. See Vivid Techs., 200 F.3d at 803.” slip op. at 8

      “f) Motivation to combine Ericsson and TS 25.331 Petitioner contends that a “POSITA would have been motivated to combine Ericsson and TS 25.331 because they are directed to similar technologies and a skilled artisan would have understood the benefits of combining these two references,” and “would have understood that there was a high likelihood of success in making the combination.” Pet. 34 (citing Ex. 1003 ¶¶ 156–157). In particular, the references “are both reasonably pertinent to the problem faced by the inventor, namely protocols for handover in a telecommunications system.” Id. (citing Ex. 1003 ¶ 158). According to Petitioner, the combination “involves the predictable use of interchangeable prior art elements according to their established functions” more than routine engineering.” Id. at 37 (citing Ex. 1003 ¶ 174). At this stage of the proceeding, Patent Owner does not present arguments in the Preliminary Response addressing the specific merits of Petitioner’s contentions with respect to the motivation to combine Ericsson and TS 25.331. See generally Prelim. Resp. 15–18. We find availing Petitioner’s contention that Ericsson and TS25.331 are “directed to similar technologies,” and that a “skilled artisan would have understood the benefits of combining these two references.” Pet. 34. On this preliminary record, we are persuaded that Petitioner has made a sufficient showing that a POSITA would have had a reason to combine the teachings of Ericsson and TS 25.331.” slip op. at 20

      “Petitioner, relying on the testimony of Dr. Kakaes, contends that a person of ordinary skill in the art (POSITA) “would have had a B.S. in Electrical Engineering or a related field with at least three years of experience designing, developing, and/or testing telecommunication systems,” and “would also have familiarity with the wireless standards and well-known protocols for accessing wireless networks existing at the relevant time,” wherein “[m]ore education may supplement practical experience or vice versa.” Pet. 12–13. At this stage in the proceeding, Patent Owner does not contest Petitioner’s proposal or offer an alternative. On this record, we are persuaded that Petitioner’s proposal is consistent with the technology described in the Specification and the cited prior art. For purposes of this Decision, we adopt Petitioner’s proposed level of skill.” slip op. at 10

For example, limitation 1D of claim 1 recites “adapting the successive determinations to shift the playback quality based on the factor to achieve continuous playback of the video using the streamlets of the highest quality copy of the video that is determined to be sustainable at that time.” Claim 13 recites a similar limitation. Petitioner contends “[t]he claims’ plain language only requires that the shift in playback quality is made ‘to achieve continuous playback.’” Pet. Reply 1 (citing claim 1). According to Petitioner, “shifting quality ‘to achieve continuous playback’ is aspirational, not limiting, language.” Id. (citing Bristol-Myers Squibb Co. v. Ben Venue Labs., 246 F.3d 1368 (Fed.

Although Patent Owner points to the District Court’s Memorandum in Support of Claim Construction Order (id. at 32 (citing Ex. 2002, 26)) to support its contention that the District Court construed the term “enabled,” as we determined in the Decision to Institute, this portion of the District Court’s Memorandum merely discusses that “hybrid device” is not indefinite, and discusses exemplary operations of the “hybrid device” from which a POSITA “could reasonably ascertain the scope of the claim.” See Dec.

Thus, for consistency, and for the reasons given in the previous related proceedings, in this proceeding, we also determine that the claims do not invoke 35 U.S.C. § 112 ¶ 6, as discussed below.” slip op. at 9

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “would have found it obvious to combine the teachings of Dua and Giobbi ’157 (Pet. 31), citing Dr. Wolfe’s supporting testimony (Ex. 1003). In particular, Petitioner posits that POSITA would have been motivated and found it obvious to “securely store the financial information in its tamper-resistant tag ‘to prevent hackers from retrieving confidential information’” (Pet. 31 (citing Ex. 1003 ¶¶ 105, 109)), as disclosed by Giobbi ’157. As Petitioner points out, Giobbi ’157 teaches “credit/debit card information” that is stored in a “profile memory field 232” in the “physical access secured and tamperproof” memory (id.; see Ex. 1006 ¶¶ 36, 42, 63), and we find persuasive Petitioner’s contention that a POSITA would have reasonably expected to succeed in “storing the ‘credit card profile or other payment information’ in Dua’s tamper resistant tag memory,” wherein such combination “would have been no more than combining prior art elements according to known methods to yield predictable results.” Id. (citing Ex. 1003 ¶ 158).” slip op. at 40

    • Skill levelOther

      “Principles of Law B. A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, “would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of non-obviousness.9 See Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966).” slip op. at 25
