“B. Level of Ordinary Skill in the Art Petitioner argues that at the time of the ’634 patent (July 2018), a person of ordinary skill in the art would have had “a bachelor’s degree in electrical engineering, computer science, computer engineering, or a similar major with at least two years of experience in the field; or a master’s degree with specialization in the field,” where “[a] person with less education but more relevant practical experience may also meet this standard.” Pet. 7 (citing Ex. 1003 ¶¶ 12–13). Petitioner further argues that a person of ordinary skill in the art would have had knowledge of “[d]esigning and using systems that include endpoint devices (e.g., client devices) and servers for establishing network connections and data transfer,” “[r]ecognizing and applying the client-server architecture,” and “[u]sing and applying concepts from known telecommunication and networking frameworks, protocols and standards, including TCP/IP, IEEE 802.11, VoIP, cellular systems and other known frameworks and standards.” Id. (citing Ex. 1003 ¶ 14). Patent Owner does not address the level of ordinary skill in the art in its Preliminary Response. Based on the record presented, including our review of the ’634 patent and the types of problems and solutions described in the ’634 patent and cited prior art, we agree with Petitioner’s definition and apply it for purposes of this Decision. See, e.g., Ex. 1001, col. 1, ll. 4–29 (describing in the “Background” section of the ’634 patent a “network connection between two endpoints” and known methods of reaching “full effective bandwidth capacity” in a network).” slip op. at 8

“C. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.100(b). Petitioner notes that it proposed a construction for the claim term “geographical area” in the district court case, but states that it “do[es] not believe proposing a construction for the term is necessary in this proceeding because the relied upon teachings of the prior art references are consistent with examples of ‘geographical area’ included in the ’634 patent [S]pecification.” Pet. 8. Patent Owner argues that “[t]he Board need not engage in express claim construction at this stage of the proceeding.” Prelim. Resp. 5. We conclude that no express interpretation of any claim term is necessary to determine whether to institute an inter partes review in this proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted) (emphasis added)).” slip op. at 9

“Petitioner has not shown sufficiently that Erskine teaches or suggests the second requirement of limitation [1c], i.e., “initiating the next network connection . . . with a transmission bandwidth based on the parameter values for the past network connection.” Petitioner’s theory is that (1) the QoS parameters in Erskine are for a “past” connection from one zone to another, (2) the sliding maximum interzone bandwidth is “based on” the QoS parameters, and (3) a new call only proceeds if the transmission bandwidth needed for the call added to the current bandwidth being used over the interzone link is less than the sliding maximum interzone bandwidth, so Erskine therefore teaches a call with a transmission bandwidth determined “based on” the sliding maximum interzone bandwidth (which in turn is determined “based on” the QoS parameters). See Pet. 27–28; Ex. 1003 ¶¶ 59–60 (similar testimony from Dr. Crovella). As Patent Owner points out, however, Erskine only makes “a binary, accept/reject decision as to whether to allow a new call to proceed based on a comparison between the bandwidth needed for the call and a predetermined ‘sliding maximum interzone bandwidth value.’” See Prelim. Resp. 6–7. Specifically, the additional bandwidth that would be needed for the call is added to the current bandwidth being used on the interzone link; if the sum of those values is less than the sliding maximum interzone bandwidth for the link, the call “proceeds”; otherwise, it is “blocked.” Ex. 1004, col. 4, ll. 36–40, col. 6, l. 55–col. 7, l. 10, col. 8, ll. 36–43, col. 9, ll. 9–26, col. 10, ll. 23–25 (the sum is compared to the sliding maximum interzone bandwidth “to determine whether enough bandwidth is available to proceed with the new call”), Fig. 3 (steps 308, 310, and 312). Erskine repeatedly refers to the bandwidth for the new call as the amount of bandwidth that is “necessary” or “required” to handle the call. See, e.g., id. at col. 1, ll. 43–57 (“an amount of bandwidth necessary to handle the new call”), col. 6, ll. 61–64 (“the additional bandwidth required (of the new call)”), col. 8, ll. 36–40 (“the bandwidth necessary for the new call”), col. 9, ll. 16–21 (“the anticipated additional bandwidth necessary for the new call”), 54–56 (“the bandwidth amount the new call will utilize (if connected)”), col. 10, ll. 21–23 (same), 41–43 (same), col. 12, ll. 1–2 (“an amount of bandwidth necessary to handle the new call”). It is that value—determined prior to the addition and comparison to the sliding maximum interzone bandwidth—that will be used for the new call if it is allowed to “proceed[].” Id. at col. 6, ll. 64–67 (if the sum is less than the sliding maximum interzone bandwidth, the call “proceeds” and “the QoS table is updated with the additional bandwidth used by that call”). Erskine does not describe the transmission bandwidth for the new call as being based on any parameter values for a past network connection, but rather as “whatever bandwidth the system determined is necessary for the additional call.” See Prelim. Resp. 8–9. In other words, the transmission bandwidth needed for a new call is predetermined and independent of whatever the sliding maximum interzone bandwidth is currently. See id.” slip op. at 15

“of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197. Accordingly, we determine there is insufficient evidence to support Petitioner’s conclusory statements that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed.” slip op. at 23

“Petitioner states that none of the claims require express construction and the claims should receive their plain and ordinary meaning. Pet. 23. Patent Owner argues that no claim construction is necessary for the institution determination, and that the Petition “still fails if the claim term ‘on’ receives its plain and ordinary meaning -- e.g., physically in contact with or directly on top of with intervening objects therebetween.” Prelim. Resp. 20 (citing Ex. 2006 ¶ 66). Although Patent Owner argues that Petitioner has construed “on” as including indirectly on; i.e., where there is no physical contact, the Petition addressed now-disclaimed claim 18, and the Petition does not advance any construction for the remaining claims.

Petitioner contends that a person of ordinary skill in the art (“POSITA”) would have had “a bachelor’s degree in electrical engineering or a similar discipline, along with 2–3 years of professional experience working with (e.g., researching, designing, or teaching) monolithic 3D structures and NAND memory devices, or an equivalent level of skill, knowledge, and experience (e.g., an advanced degree may replace 1 The Leahy-Smith America Invents Act, Pub.

See Ex. 1001, (63). Thus, we refer to the AIA version of 35 U.S.C. § 103. 2 Costa, US 2018/001282771 (filed Feb. 28, 2017, published June 28, 2018) (Ex. 1005, “Costa”). 3 Oh, US 2017/0154892 A1 (filed June 10, 2016, published June 1, 2017) (Ex. 1006, “Oh”). some of the professional experience). Pet. 23–24. Petitioner also asserts that a POSITA “would have been aware of and generally knowledgeable about 3D NAND’s structure, how it is manufactured, and its component parts.” Id. (citing Ex. 1003 ¶¶ 36–40). Patent Owner does not take a position on the level of ordinary skill in the art. Prelim. Resp. 11; see also Ex. 2006 ¶ 34 (applying Petitioner’s definition of a POSITA to the opinions set forth in the declaration but reserving the right to opine to an alternative level of a POSITA). At this stage of the proceeding, we adopt Petitioner’s definition of a POSITA as it appears consistent with the level of ordinary skill in the art that is reflected by the prior art of record.” slip op. at 6

“We agree with Patent Owner that the Petition fails to sufficiently show that Costa teaches a “second stacked layer disposed on the third channel structure” as required by apparatus claim element [11.E]. The Petition asserts that Costa’s second alternating stack 232, 242 is formed “on the top surface of joint-level material layers.” Pet. 64. However, Costa refers to the term “joint-level material layers” as representing layers 175–177, not the asserted third channel structure 173. Ex. 1005 ¶¶ 166, 178, 184–85; see Ex. 2006 ¶ 77. Thus, under Petitioner’s characterization, which is consistent with Costa, Costa’s second alternating stack is not formed on the third channel structure, but instead, “on the top surface of the joint level material layers” that surround the third channel structure. Because Petitioner has not explained how a second alternating stack on the surface of the joint material layers teaches a second alternating stack disposed on the third channel structure, Petitioner has not met its obviousness burden for limitation [11.E].” slip op. at 11

“In particular, we agree with Patent Owner that Cantor does not teach or suggest contacting a ‘tissue section’ with its beads, let alone that its beads could be contacted with a tissue section to identify spatial location. Prelim. Resp. 36–48. In this case, we are persuaded by the testimony of Dr. Cantor, sole inventor of Cantor (Ex. 2002 ¶ 29), that Cantor’s nucleic acid samples are made in bulk from the extraction of nucleic acids from a biological sample and mixed together “to create the sample nucleic acid prior to mixing that with the solid phase nucleic acids to capture molecule(s) from the sample nucleic acid.” Id. at ¶ 36 (citing EX.1031 1:5–6). More specifically, according to Dr. Cantor, “[f]or bulk-analysis methods, nucleic acids are extracted from the different types of cells within a tissue sample without preserving their spatial distribution.” Id. at ¶ 19. Dr. Cantor further explains that in bulk-analysis methods, the mixture is analyzed to determine if a particular nucleic acid was present in the tissue sample or not. They cannot, however, determine where the molecule was in the tissue sample. As such, bulk-analysis techniques provide no information about spatial location of biological molecules in tissue samples. This is in contrast to spatial analysis methods such as those claimed in the ’879 patent which can determine both if a biological molecule was present in a tissue sample and where the molecule was in the tissue sample. Id. at ¶¶ 16–17. Although we recognize that Cantor discloses “providing the beads according to an (X,Y) array” (Pet. 24, 30–31 (citing to Dr. Puglisi, Ex. 1102 ¶¶ 133, 155, respectively), this disclosure makes no mention of using this array to map where the nucleic acids of Cantor came from relative to the original sample, let alone when that original sample is a tissue.

“3. Discussion Petitioner challenges whether certain elements of independent claim 1 are supported by the’124 provisional and/or whether the ’879 patent’s priority chain is intact. Pet. 57–66. Having considered the parties’ positions and evidence of record, however, we agree with Patent Owner’s written description analysis, summarized above, and find that (1) the’124 provisional provides adequate written description support for each of the challenged claim elements; (2) the ’879 patent’s priority chain is intact; and (3) the ’879 patent is therefore entitled to the priority date of April 5, 2010. Consequently, Frisen is not prior art to the challenged claims.
