      “record, we adopted the following definition of the level of ordinary skill in our Decision on Institution: [A] POSITA would have had a bachelor’s degree in a pertinent discipline, such as mechanical engineering, physics, applied physics, product design, or a related field, and would also have had 2–4 years of experience working with electronic displays, including the thermal management, product design issues, and failure modes, associated with such displays, or 5–7 years of experience in the field working with electronic displays and would have developed a similar understanding of thermal management, product design issues, and failure modes, associated with electronic displays. Dec. on Inst. 11. The parties’ positions have not changed since the time of institution, and we discern no reason to change the definition. Thus, we apply the same definition. We are satisfied that this definition comports with the level of skill necessary to understand and implement the teachings of the ’595 patent and the asserted prior art. Notwithstanding, we note that our analysis would not change if we adopted either party’s proposed definition in toto.” slip op. at 12

      “appear nowhere outside of the claims in the ’595 patent. This fact alone tends to undermine Patent Owner’s suggestion that the “posterior surface” must be distinct from the “rear side.” In addition, Patent Owner’s cited portions of the Specification merely refer to the “posterior surface” as being the surface opposite that on which the LEDs are mounted to which heat from the LEDs is transferred. See Ex. 1001, 4:53–55, 4:57–60. They are inconclusive as to whether the “posterior surface” must be distinct from the “rear side.” Further, Mr. Gershowitz’s testimony in support of a “distinct” construction is based on his interpretation of the words “on the” in claim 4’s recited “posterior surface on the rear side of the PCB.” Ex. 2006 ¶ 128. Specifically, he testifies that “[i]f the posterior surface was the rear side of the PCB, the claim would have said so.” Id. He does not cite any support in the Specification of the ’595 patent for his interpretation. See id. Given that his testimony amounts to speculation divorced from the context of the Specification, Mr. Gershowitz’s testimony is entitled to little weight. We also have considered Mr. Smith-Gillespie’s testimony in support of Petitioner’s contention that an ordinarily skilled artisan “would have understood that the rear outermost surface of the PCB is the recited ‘posterior surface.’” Pet. Reply 20 (citing Pet. 83; Ex. 1002 ¶ 243). He cites a passage in the Specification of the ’595 patent that states: “The PCB may comprise a metal core PCB and the posterior surface of the PCB may be metallic so that air within the constricted convection channel may cool the metallic posterior surface (and subsequently the backlight assembly) more easily and efficiently.” Ex. 1002 ¶ 243 (emphasis omitted) (quoting Ex. 1001, 4:60–65). We accord Mr. Smith-Gillespie’s testimony more weight than Mr. Gershowitz’s testimony given that Mr. Smith-Gillespie’s testimony is rooted in disclosures about metal core PCBs in the ’595 patent. It also gives some credence to the notion that the “posterior surface” and the “rear side” could be one and the same.

      “1. Motivation to Combine Becerra and Couckuyt Petitioner argues that a person of ordinary skill in the art would have been motivated to combine the teachings of Becerra and Couckuyt because such a person would have recognized that Couckuyt discloses useful techniques of assigning data to Becerra’s charts, including assigning data to each axis. Pet. 34 (citing Ex. 1005 ¶¶ 19, 52, Fig. 5; Ex. 1003 ¶ 224). Petitioner contends that Couckuyt discloses associating data from a “spreadsheet document” with a chart, such as a “bar graph.” Id. at 35 (citing Ex. 1006, 6:1–37; Figs. 3a, 3c). below. Petitioner’s annotations to Figure 4 identify “Drop Zones” in red and “Data Fields” in Blue. Id. at 36. Petitioner contends Couckuyt discloses a “drag-and-drop user interface (DDUI) . . . associated with a data source, such as the two-dimensional data source 300,” and Figure 4 illustrates the DDUI permitting “value data fields and the characteristic data fields . . . to be dragged and dropped into drop zones.” Id. at 35–36 (citing Ex. 1006, 7:10–13). Petitioner contends that a “primary benefit of the charting DDUI is that the user can quickly change the data that is being presented in the chart,” and using Couckuyt’s techniques, a user can “quickly change the data” and see the desired effects. Id. at 36 (citing Ex. 1006, 1:18–19; Ex. 1003 ¶ 228). Petitioner contends that when Becerra’s control panel includes multiple charts, Couckuyt’s techniques would allow dragging-anddropping data from a data source to multiple charts, and would simplify the process of assigning data to multiple control panel components. Id. at 36–37 skill in the art would have also had a reasonable expectation of success combining Becerra with Couckuyt because the combination would amount to nothing more than incorporating Couckuyt’s well-known drag-and-drop techniques into Becerra’s system. Id. at 37 (citing Ex. 1003 ¶¶ 229–231). Patent Owner responds that Couckuyt focuses on selecting a data icon that corresponds to dragging and dropping data fields, not dragging and dropping data, while Becerra teaches that selecting various data ranges from the spreadsheet is desirable. PO Resp. 36–37 (citing Ex. 1004 7:48–52; Ex. 2001 ¶ 146). According to Patent Owner, a person of ordinary skill in the art would not have been motivated to merely select data fields that do not limit the selected data in any way. Id. Patent Owner further argues Becerra’s method of binding components to a spreadsheet range and extracting formulas from a spreadsheet teaches away from the multiple chart generation scheme of Couckuyt that uses drag and dropping of data fields. Id. at 37. According to Patent Owner, Couckuyt is directed to the need for a charting DDUI that can generate multiple charts at the same time and such a need does not exist in Becerra which in turn is focused on creating a control panel that is an interactive graphics simulation. Id. (citing Ex. 1004, 1:66–67, 2:5–8; Ex. 1005 ¶ 11; Ex. 2001 ¶ 148). Based on our review of the complete record, we determine that” slip op. at 31

      “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.

      “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.

      “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.

In addition, the specification includes no special definition of that phrase that supports importing Patent Owner’s proposed narrowing limitation into the claim. Furthermore, we are directed to no disclaimer of claim scope during patent prosecution that would support Patent Owner’s twice-rejected argument that the phrase “matrix material” in claim 1 excludes embedded dopants and dispersed agglomerations.

      “We find that Petitioner establishes by a preponderance of the evidence that Choulis anticipates claim 13. We agree with Petitioner, in that regard, that Choulis explicitly teaches “using spin-coating as a method for depositing materials, which involves a simultaneous application process” as required by claim 13. Reply 16 (citing Pet. 40–41; Ex. 1044 ¶ 45).16 We 15 Petitioner raises Djobo as a background reference supporting that Choulis anticipates deposition of PVK by evaporation. Pet. 41. Patent Owner counters that Djobo, to the contrary, shows that Choulis does not teach deposition of PVK by evaporation. Resp. 48. In other words, both parties cite Djobo in connection with the ground based on anticipation by Choulis. Against that backdrop, we determine that Patent Owner waives any argument that Petitioner improperly cites Djobo as a background reference in support of the anticipation challenge, which is based on Choulis alone. Resp. 48 (nowhere asserting that the challenge is deficient on that basis). That waiver arises because no argument, in that regard, is raised in Patent Owner’s Response see Inst. Dec. 34 (“The Board shall deemed waived any issue not raised by Patent Owner in a timely response to the Petition . . . .”). 16 Patent Owner’s statement that “spin coating tends to cause phase separation” is not developed adequately on this record and, therefore, is further agree with Petitioner that Patent Owner “has not contested this point.” Resp. 48. “Therefore, there is no genuine dispute regarding the unpatentability of claim 13,” although Patent Owner raises “arguments concerning evaporation, which is a distinct process from spin-coating” relevant to the additional limitations of claim 14. Reply 16. We determine that Petitioner establishes by a preponderance of the evidence that Choulis anticipates claim 13. Patent Owner, however, has the better position on whether Choulis anticipates claim 14, which “includes the requirement of applying matrix materials via evaporation coating.” Reply 16. Petitioner seems to abandon that challenge in the Reply by raising arguments that appear, on this record, to bear exclusively on whether the subject matter of claim 14 would have been obvious over Choulis.17 Id. at 16–17. Those arguments are insufficient to counter Patent Owner’s reasons why Choulis does not anticipate the “evaporation coating” limitation of claim 14. Compare id., with Resp. 48. On this record, therefore, we determine that Petitioner does not establish by a preponderance of the evidence that Choulis anticipates claim 14. unpersuasive to persuade us “that Choulis does not have three matrix materials.” Sur-reply 15. That argument runs counter to Choulis’s explicit, intrinsic disclosures, which illustrate (Ex. 1004, Fig. 4) and describe (id. ¶ 30) an organic light emitting layer composed of three matrix materials. See Pet. 24–25 (citing Ex. 1004, Fig. 4, ¶ 30); see also Ex. 1003 ¶¶ 85–88 (persuasive declaration testimony of Dr. Holmes, cited at Pet. 24–25). 17 There is some confusion on this point, given that both parties sometimes collapse, into a single argument, whether Choulis anticipates or renders obvious claim 1.

      “On this record, therefore, we determine that Choulis, at minimum, suggests that a person of ordinary skill in the art at the time of the invention would have recognized PMMA as a suitable alternative to PVK in Choulis’s Figure 4 embodiment, notwithstanding any differences raised by Patent Owner. Ex. 1004 ¶ 44. Patent Owner’s argument that no disclosure in Choulis suggests that an ordinarily skilled artisan “would have found it desirable to use PMMA in place of PVK in Choulis’s devices” misses the mark, where Choulis includes both PMMA and PVK in lists of materials suitable for use as host or matrix materials. Resp. 38; Ex. 1004 ¶ 44. “Our caselaw is clear. It’s not necessary to show that a combination is ‘the best option, only that it is a suitable option.’” Intel Corp. v.

The suggestion for that substitution is set forth unambiguously in Choulis’s listing of both “PVK” and “PMMA” as materials suitable for use as a first “host” material in Choulis’s organic functional layer; that is, “the light emitting layer” that is “described above” in Figure 4. Ex. 1004 ¶ 44. ii. Alternative Reasoning for Replacing PVK with PMMA Patent Owner counterargues that using PPMA in place of PVK would have been understood to “upset the hole and electron balance,” as well as “affect hole-charge recombination,” and “degrade the performance of the resulting OLED system.” Resp. 37. Petitioner responds with evidence that “it would have been a routine task for” an ordinarily skilled artisan “to optimize the composition of each component within the light-emitting layer to achieve the desired charge balance.” Reply 11 (citing Ex. 1004 ¶ 24).

      “First, we find that Hackborn clearly discloses an embodiment in which swiping the finger, not just mere contact without motion (i.e., a tap), moves the blades of grass in the background wallpaper. Hackborn explicitly states: “In the example shown in FIG. 1, a user is swiping her finger across a touch-sensitive display screen of the computing device. In response, the blades of grass 105 displayed in the area of the screen swiped by the user are caused to bend or sway as if contacted by the user’s finger during the swipe.” Ex. 1004 ¶ 28. Because this description expressly refers to “swiping” or moving the finger “across” the display screen, it does not encompass a mere tap, or contact by the user that does not move on the display screen. If a single-tap-contact embodiment for moving the blades of grass in the background wallpaper is disclosed, it would be in an embodiment different from the swiping embodiment. Here, Petitioner is relying only on the swiping embodiment for moving the blades of grass in the background wallpaper. Thus, we disagree with Patent Owner that Hackborn discloses no need to distinguish a tap from a swipe. We find that in the swipe embodiment, it is important to distinguish a tap from a swipe, and thus there is reason, as Petitioner contends, for one of ordinary skill in the art to look to Westerman for implementation details on how to make such a distinction. Specifically, for recognizing a swipe from a tap, Westerman describes determining whether the finger path displacement exceeds a predetermined threshold (Ex. 1005 ¶¶ 19, 61), and examining the initial velocity of the contact at contact’s touchdown (Ex. 1005 ¶¶ 19, 62). As for Patent Owner’s noting that in several instances Hackborn generally refers to a user’s finger contacting items on the wallpaper, that does not undermine Petitioner’s positions, because in the “swipe” embodiment, the referenced contact would be a swipe, and not a single tap without any motion of the finger.” slip op. at 17

The reference in claims 17, 37, and 38 to “the at least some of the plurality of images” identifies the at least some of the plurality of images first recited in claim 1 on which claim 17 depends, and the at least some of the plurality of images first recited in claim 23 on which claims 37 and 38 depend. According to independent claims 1 and 23, however, the displaying in sequence of the at least some of the plurality of images must be based in part on the magnitude of the first contact.

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
