“III. ANALYSIS A. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art: would have had at least a bachelor’s degree in computer science, electrical engineering, or a related field, and at least two years of work or research experience in the field of content delivery management or networks. Work experience can substitute for formal education and additional formal education can substitute for work experience. Pet. 12 (citing Ex. 1006 ¶ 70). Patent Owner asserts that “the Board does not need to resolve the appropriate level of skill for a POSA [person of ordinary skill in the art] for purposes of deciding institution because the Petition fails under any articulation of a POSA.” Prelim Resp. 10.

- Disclosure Requirements (§112) › Written description (Ariad)Written description adequateEntitled to earlier dateDecided for patent owner
“We consider the disclosures of the Provisional Application, which refer to cases 1 and 2, in which requests are redirected to an origin server for lower popularity content and to a parent server for medium popularity content at steps 522 and 524 as shown in Figure 5, respectively, wherein the edge server receives a redirect from the popularity service without a “followme” flag. See Ex. 1011 ¶¶ 43, 44. The Provisional Application also discloses that, by comparison, if there is a “follow-me” redirect sent to the edge server, it obtains and caches a resource as shown at step 528 for higher popularity content. Id. ¶ 44. On this record, as Patent Owner asserts, these disclosures are consistent with technical reasons provided in the Provisional Application for instructing the edge server not to cache unpopular resources. See Ex. 1011 ¶¶ 68–69. In light of these disclosures, we preliminarily find support for Dr. Shenoy’s testimony that, even with the words “instruction to not cache” are not literally recited in the Provisional Application, caching and not caching are alternative options that indicate the instruction to the edge server that will be implemented for each option. See Ex. 2014 ¶ 56. Further, these disclosures provide support for Dr. Shenoy’s testimony that the disclosures “reasonably convey to those skilled in the art that Patent Owner had possession of the edge server receiving an instruction to not cache the resource (and instead simply forward the redirect).” Id. In re Johnson states that “it is not true that the factual context out of which the question under § 112 arises is immaterial. Quite the contrary. Here, . . . the ‘written description’ in the [] specification supported the claims in the absence of the limitation, and that specification, having described the whole, necessarily described the part remaining.” See Johnson, 558 F.2d at 1019. This is consistent with M.P.E.P. § 2173.05(i) which states, “[i]f alternative elements are positively recited in the specification, they may be explicitly excluded in the claims.” M.P.E.P. § 2173.05(i). Further, “the failure of the specification to specifically mention a limitation that later appears in the claims is not a fatal one when one skilled in the art would recognize upon reading the specification that the new language reflects what the specification shows has been invented.” All Dental Prodx, LLC v. Advantage Dental Prod., Inc., 309 F.3d 774, 779 (Fed. Cir. 2002). Even though we do not discern that the Provisional Application explicitly discloses an “instruction to not cache,” at least on this preliminary record, and for the purposes of this Decision, there is positive recital of instructions to cache in the Provisional Application and Petitioner has provided sufficient supporting evidence that caching and not caching are alternative options. Further, there is sufficient evidence, in the context of the disclosures of written description support in the Provisional Application, providing support for Dr. Shenoy’s testimony that Patent Owner had possession of an edge server receiving an instruction to not cache the resource. Nonetheless, we invite additional briefing on these issues, including issues relating to alternative options of caching and not caching. On this preliminary record, we find that the ’573 patent has a priority date of April 2, 2008, which predates the earliest possible date on which Newton-471 could be effective as prior art, September 30, 2014 (the date on which the earliest application in the priority chain of Newton-471 was filed). Accordingly, we preliminarily find that Newton-471 is not prior art to the challenged claims. Thus, on the present record, Petitioner has not demonstrated a reasonable likelihood that it would prevail in showing that claims 1–20 are anticipated by Newton-471.” slip op. at 13

“Dr. Mowry further attests that “A POSITA would have understood Glines’s disclosure of providing content from an origin source would have included supporting more than one origin source (e.g., more than one website or content provider[)].” Ex. 1008 ¶ 262 (citing Ex. 1002, 12:11–22 (storing replica files that originate at an origin server 40), 13:21–14:3 (requesting “example.com”)). That statement, however, goes only to what Glines might be capable of doing, not to whether one would have modified Glines to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[o]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed inventions.”). Dr. “content providers” limitation, stating that it “would have been nothing more than replicating Glines’s teaching of storing and providing content associated with one origin server, with expected results.” Ex. 1008 ¶ 263. That statement, however, is unsupported, and moreover, does not explain how such replication would occur or what results would be expected. Prelim. Resp. 25–26. At this stage in the proceeding, Dr. Mowry’s testimony amounts to a “conclusory generalization” that does not provide the “reasoned explanation” sufficient to show that a limitation missing in the cited art was taught by the knowledge in the art.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner
“one memory portion above or below another portion establishes a relative top and bottom. For example, claim 5 is directed to a “program method of memory” that requires a second portion formed above the first portion. A second memory portion that is formed above a first memory portion would be on top of the first portion. Given that the claims themselves identify relative vertical locations of the memory portions (i.e., second memory portion is above the first portion), it follows that claim terms referring to the top and bottom of word lines within the memory portions also refer to relative vertical locations of the word lines within the memory portions. Thus, we understand the plain and ordinary meaning of claim language referring to first and second memory portions that comprise word lines “from bottom to top” to mean that the word lines of the memory portions are arranged vertically from the bottom end of the memory portion toward the top of the memory portion (i.e., from bottom to top). Our understanding that the term “from bottom to top” refers to the vertical arrangement of word lines in the memory portions from bottom to top and not from source end to drain end is supported by the ’941 patent Specification, which does not refer to source or drain side of the word lines. See generally Ex. 1001. Rather, the ’941 patent illustrates and describes figures of memory devices having word lines arranged vertically from bottom to top. For example, Figures 1–11 each depict “a memory” having vertically arranged word lines. See id. at 2:37–55, Figs. 1–11. The Specification describes embodiments with first, second, and/or third memory portions as including various word lines “from bottom to top” and that the memory portions are formed above or below each other, thus supporting that the claim term “from bottom to top” is used according to its plain and ordinary meaning of from bottom to top and not from source side to drain side.

“These disclosures in the ’031 patent indicate that the staircase structure is etched along the x-, y-, and z-axes, the dielectric filling structure fills the spaces in the x-, y-, and z-directions created when the staircase structure is etched, and the staircase structure surrounds the memory structure in the x-y plane. Therefore, based on the current record, it appears that the dielectric filling structure surrounds or encircles the staircase structure on four sides (front, back, left, and right) in the x-y plane. This understanding of “surround” is consistent with the way “surround” is used in the ’031 patent and with the plain and ordinary meaning of “surround.” See, e.g., 2:12–14 (“the supporting pillar is filled with at least one of an insulating material and a pillar-support material surrounded by the insulating material”), 10:25–27 (periphery region 120 “can surround core region 110” and “can also be under core region 110, depending on the type of the memory device”), 15:49–53 (“Charge trapping film 416 can also include a storage unit layer (memory layer) over and surrounded by the block dielectric layers for trapping charges and forming a plurality of charge storage regions along the z axis.”), 18:25–26 (“In some embodiments, the insulating liner/spacer layer surrounds the support material.”); Ex. 2001– 2004.

“currently before us, and for purposes of this Decision, we agree with Patent Owner that “surrounding” requires more than structures on two sides of the object. The Specification repeatedly uses “between” to describe objects in the middle of two structures. See, e.g., Ex. 1001, 3:65–67 (“a layer can be located between any pair of horizontal planes between, or at, a top surface and a bottom surface of the continuous structure”), 4:56–57 (“dummy channel holes are formed between adjacent GLSs”), 7:12–15 (“one or more dummy channel structures may be located between two dummy source structures, and vice versa”), 7:16–17 (“at least one dummy source structure may be located between two staircase contacts”), 9:63–64 (“an insulation layer (not shown) is formed between substrate 102 and memory stack 160), 17:42–44 (“at least one dummy source structure is located between the first and second staircase contacts”). In contrast, the Specification uses “surrounding” to indicate an object in the middle of more than two structures. See, e.g., id. at 6:38–41 (“multiple dummy source structures, such as the four dummy source structures indicated by a diamond shape 146, may surround a staircase contact, such as staircase contact 122”), 6:60–63 (“A plurality of dummy channel structures, such as the four dummy channel structures indicated by square shape 148, may surround a staircase contact.”), 7:31–34 (“four dummy channel structures indicated by dashed-line square shape 142 are surrounded by eight dummy source structures indicated by an octagon 144”), 7:38–40 (“one dummy channel structure indicated by dashed-line square 147 is surrounded by four dummy source structures indicated by a diamond 149”), 17:61–62 (“at least one dummy channel structure is surrounded by at least four dummy source structures”), 17:63–64 (“at least two dummy channel structures are surrounded by at least six dummy source structures”), 17:65–67 (“at least four dummy channel structures are surrounded by at least eight dummy source structures”). That claim 15 recites “wherein at least one dummy channel structure is surrounded by at least four dummy source structures” and claim 14, from which claim 15 depends, recites “wherein a subset of the dummy channel structures is surrounded by the plurality of dummy source structures,” does not require a different result. While we agree with Petitioner that the doctrine of claim differentiation may “impl[y] that ‘surrounded’ in independent claim 14 covers implementations in which fewer than four dummy source structures surround a single dummy channel structure,” that does not require that “surround” encompasses a dummy channel structure between two dummy source structures. Pet. 28 (citing Ex. 1001, claim 15 (21:9–11)). For example, three dummy source structures surrounding one dummy source structure could satisfy claim 14 but not claim 15 (“at least four dummy source structures”). Accordingly, we determine that “surrounding” in claim 1 of the ’872 patent does not encompass structures on only two sides of an object. We need not provide an explicit construction of “surrounding,” as terms in controversy need to be construed only to the extent necessary to resolve the controversy.

“Regarding the claimed “predefined threshold value” or “predefined illuminance,” Petitioner asserts that “Alden’s system can ‘provide illumination to independently controlled segments [e.g., ‘subsections’] each operable within a range of intensities between the high and the low beam state” and that Alden’s “intensities in between high beam and low beam (e.g., medium) are the claimed ‘predefined threshold value’ which the low beam would be below and the high beam would be above.” Pet. 25. We tend to disagree with this analysis, as it does not appear that a “range of intensities” is a “predefined threshold value” or “predefined illuminance,” if those terms are given their ordinary meaning. We thus conclude that, on this record at least, Petitioner has not shown a reasonable likelihood that Alden anticipates these claims. Regarding obviousness in view of Alden alone, Patent Owner argues that Petitioner has “failed to establish or demonstrate multiple elements that are required to support an obviousness conclusion, including explaining how Alden must be modified (i.e., identifying the differences between the claimed invention and Alden) and explaining why a POSA would be motivated to so modify Alden (i.e., providing some articulated reasoning with some rational underpinning to support an obviousness conclusion).” Prelim. Resp. 37. We agree. It does not appear that Petitioner has provided any basis on which to account for differences between Alden and the challenged claims based on Alden’s disclosures alone.” slip op. at 9

“First, Patent Owner asserts that Alden is “fatally ambiguous” and “fails to provide an enabling disclosure” because it describes the use of two-dimensional sensors and switch arrays (as shown in Figure 3, below left), but the headlamp embodiment on which Petitioner relies (which is depicted in Figure 5, excerpted below right), is illustrated as having just a single line of LEDs. See Prelim. Resp. 19–23. Alden’s Figures 3 and 5 We find this argument unpersuasive because we conclude, on the present record, that one of ordinary skill in the art (see Section II.A), would understand that Figure 5 is a schematic/sectional type of drawing intended to show generally how the system components are connected and how the LEDs would project light through the lens, and that for clarity it omits other LEDs that would be necessary to produce a two-dimensional lighting pattern. We find that the skilled artisan would recognize that a headlamp intended to produce a pattern similar to that reflected in the control circuits of Figure 3 would include additional rows of LEDs passing through the center of the lens at different angles arranged around the center of the lens. Alternatively, we conclude that one of ordinary skill in the art wishing to use a headlamp with just a single line of LEDs would understand that the sensor and/or control circuitry would need to be tailored to such an arrangement.” slip op. at 9

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“We have considered Patent Owner’s argument, but find that Petitioner has articulated sufficient reason to combine the no-uplink teaching of R2-104515, and has sufficiently articulated the manner of such combination. Petitioner points to TS 36.300 V10.0 as presenting the situation in which uplink resources may not be provided. Pet. 59–60, 56–59 (pointing to Patent Owner’s infringement contentions as also indicating that TS 36.300 does indeed discuss a no-uplink situation). Petitioner points to language from R2-104515 that “current agreements” permit that there may be an absence of uplink resources on secondary cells, which raises a question on how to indicate that absence. Id. at 61 (citing Ex. 1013, 1). We agree with Petitioner that, by providing options to answer a question raised in TS 36.300, it would have been obvious for a person having ordinary skill in the art to combine teachings from R2-104515 to resolve that question. Patent Owner’s argument that R2-104515 addresses a situation from TS 36.331, and not from TS 36.300 fares no better. First, TS 36.300 and TS 36.331 generally address the same standard. Ex. 1012, 13. Second, as discussed above, Patent Owner’s infringement contentions support a determination that TS 36.300 contains the no-uplink scenario that is addressed by R2-104515. Third, TS 36.300 V10.0 explicitly cites 3GPP which, through reference in this text, constitute provisions of the present document.” Id. Consequently, we do not agree that the mention of TS 36.331 in R2-104515 diminishes the reason to combine the teachings of R2- 104515 with TS36.300 V10.0. e) Determination In view of the foregoing, we determine that Petitioner has sufficiently shown, for purposes of institution, that each element of claim 2 has been taught or suggested by the combined references. We also determine that Petitioner has sufficiently shown, for purposes of institution, that a person having ordinary skill in the art would have reason to combine the references as suggested by Petitioner, and would have a reasonable expectation of success in doing so.” slip op. at 15

“However, regarding the claim 3 condition, “when a transmission of said quality notification signal coincides with that of said scheduling request signal in said transmitter,” we agree with the court’s construction in the California case: “when a transmission of said quality notification signal is scheduled to transmit or is transmitting at the same time as that of said scheduling request signal in said transmitter.” Ex. 2002, 12. The court rejected defendant’s (here Petitioner’s) equating “coincides” with “simultaneous” and relied on the statement in the ’656 patent that when the mobile terminal transmits the uplink scheduling request signal SR, the mobile terminal stops the transmission of a CQI symbol “which the mobile terminal was originally scheduled to transmit at the same timing.” Id. at 10 (citing Ex. 1001, 16:7–21) (emphasis added). As the court explained, “[t]his disclosure teaches temporarily preventing a scheduled transmission as opposed to stopping a transmission already in progress.” Id. at 11.
