“understanding that the claim 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, as asserted by Petitioner. Inst. Dec. 17. In other words, the claim terms describing the first and second portions having word lines “from top to bottom” refer to the relative vertical location of the word lines within the memory portions and not to location of the word lines relative to the source or drain. Our construction is based on the plain and ordinary meaning of the express language of the independent claims, which states that the second memory portion is formed either above or below the first memory portion. The forming of one memory portion above or below another portion establishes a top and bottom in relation to those portions. 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 is on top relative to the first portion. Similarly, claims 1 and 1 and 11, which recite a memory having a second portion formed below a first portion, establish that the second portion is on the bottom relative to the first portion. Thus, the claim language itself establishes the vertical locations of the memory portions relative to each other (e.g., a second memory portion that is above the first portion is on top, relative to 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” slip op. at 13

Petitioner contends that a person of ordinary skill in the art (“POSITA”) would have had a 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) NAND memory devices (including issues relating to the operation, e.g., programming, of said devices), or an equivalent level of skill, knowledge, and experience (e.g., an advanced degree may replace some of the professional experience).

“We disagree and find that Dong’s Figure 5a does not depict wordlines in a physical vertical orientation, but rather depicts voltage diagrams. We agree with Patent Owner’s argument, supported by persuasive testimony by Dr. Khatri, that a POSITA would have understood that Dong’s voltage charts (e.g., Fig. 5a) simply represent which voltages are applied to which word lines and do not depict the physical orientation of the wordlines. See, e.g., Ex. 2028 ¶ 171 (citing Ex. 1005 ¶ 20; Ex. 1009 ¶¶ 52–54).

“On the current record, we determine that the “modified embedded resource” may be a “link.” Both Petitioner and Patent Owner point to claim 13, which explicitly states that a modified embedded resource is a link. Because claim 13 depends from claim 1, claim 1 must be broad enough to encompass a modified embedded resource that is a link. Patent Owner also points to a statement in the ’322 patent that “[t]he embedded resource is a link.” Prelim. Resp. 18 (citing Ex. 1001, 4:26–31). Patent Owner argues that every embodiment of the ’322 patent “involves embedding the ‘modified embedded resource’ in another resource when it is returned to the client.” Paper 16, 2–3. Patent Owner cites to description in the ’322 patent of a “document” or a “page” returned to the requesting client. Id. (citing Ex. 1001, 4:42–48, 7:48–55). However, claim 15 does not return the modified embedded resource to the client, only the origin system. Claim 1 recites only that the “modified embedded resource” is returned to the client device with the content resource. Neither claim 1 nor claim 15 recite returning a document or a page containing the modified embedded resource, only the modified embedded resource itself. We acknowledge some tension with the adjective “embedded,” which Patent Owner argues requires that the embedded resource be embedded in something. Paper 16, 1–3.

Ex. 1003 ¶ 67 (citing Ex. 1005 ¶¶ 12, 26, 27, 37). On the current record, this function of Verna’s broker fulfills Dr. Russ’s characterization of an API as acting as bridge establishing a connection between client and server. Ex. 2010 ¶ 50. Verma also meets Dr. Russ’s characterization of an API as “an interface that allows the client to communicate with an application executing on the server.” Ex. 2010 ¶ 50.

- 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

“claim 1 would have been obvious over the combined teachings of Hongtao and Yu by a preponderance of the evidence. 35 U.S.C. § 316(e) (2018); see also Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). After considering the parties’ arguments and evidence of record, and weighing the testimony of Dr. Liu and Dr. Przybylski, we are not persuaded that Petitioner meets its burden of establishing, by a preponderance of the evidence, that Hongtao teaches or suggests applying a second bias voltage that is smaller than the first bias voltage in the verify stage as recited in limitation [1.d]. Hongtao is silent with respect to the magnitudes of the pre-conduction and conduction voltages. Hongtao teaches that “a pre-conduction voltage is applied to both the unselected word line and the selected word line to turn on the channels of the selected string and the unselected string.” Ex. 1005 ¶ 23. Hongtao then teaches that, in the reading phase, “[t]he gates of the unselected memory cells on the selected string are applied with a conduction voltage through the unselected word lines.” Id. ¶ 25. Hongtao, however, describes the magnitudes of the pre-conduction and conduction relative to each other. See id. ¶¶ 21–26. Petitioner and Dr. Liu point to Hongtao’s statement that “the greater the conduction voltage, the greater the read disturbance” to support its contention that the conduction voltage is smaller than the pre-conduction voltage, but that statement refers to the relationship between conduction voltage and the read interference it causes and does not compare the conduction voltage to the pre-conduction voltage. See Pet. 40 (citing Ex. 1005 ¶ 26); Ex. 1003 ¶ 120 (citing Ex. 1005 ¶ 26). We also find credible Dr. Przybylski’s testimony that Hongtao lacks the details needed to determine how the gate voltages develop over time, in particular the length of the pre-conduction period. See Ex. 2003 ¶ 96. Dr. Przybylski’s testimony is consistent with the ’957 patent’s teaching that when the pre-pulse time is long enough that the bias voltages are fully developed before the TSG transistor is switched off at the unselected memory cell string, hot carrier injection “may not be generated from the selected memory cell to the upper adjacent memory cell of the selected memory cell in the selected memory cell.” Ex. 1001, 11:60–12:1. In contrast, when the pre-pulse time is insufficient for the bias voltages to fully develop, hot carrier injection may be generated. Id. at 12:1–9. And we are not persuaded that Petitioner and Dr. Liu sufficiently rebut Dr. Przybylski’s persuasive testimony that casts doubt on Petitioner’s contention that Hongtao teaches a second bias voltage that is smaller than a first bias voltage as recited in limitation [1.d]. For example, Dr. Liu’s testimony that Hongtao teaches applying voltages on gate terminals does not adequately address Patent Owner’s argument and Dr. Przybylski’s testimony that Hongtao depicts target values for the word line voltages instead of the See Ex. 1027 ¶¶ 16–40. Neither Petitioner nor Dr. Liu adequately establish that Hongtao’s applied voltages are sufficiently developed such that the preconduction voltage actually is bigger than the conduction voltage. Petitioner’s argument that Hongtao teaches or discloses a second bias voltage that is smaller than the first bias voltage hinges on a POSITA’s interpretation of Hongtao’s Figure 2. In light of Hongtao’s dearth of details regarding the absolute or relative magnitudes of the pre-conduction and conduction voltages, and Dr. Przybylski’s unrebutted testimony that Hongtao does not provide sufficient information to ascertain the actual bias voltages that will be applied on the gate terminals of the memory cells over time, we are not persuaded that Petitioner carries its burden of establishing that Hongtao discloses limitation [1.d]. For these reasons, we determine that Petitioner does not establish by a preponderance of the evidence, that independent claim 1, and claims 2–6 that depend, directly or indirectly, therefrom, would have been obvious over the combined teachings of Hongtao and Yu.” slip op. at 15

“Without the benefit of its provisional filing date, Seet, filed on February 17, 2005, is not prior art to the ’848 patent, having an uncontested benefit to the May 27, 2004 filing date of its provisional. Because each of Petitioner has not shown a reasonable likelihood of prevailing on any of its unpatentability assertions. III.

“Petitioner fails to show that the full scope of claim 9 of Seet is described in the Seet provisional. Seet expressly defines the claim term “media,” stating that, as it is “used herein,” “media” includes audio, video, software, and pictures. Ex. 1006 ¶ 50 (“Media content may include one . . . of audio . . ., video . . ., software . . ., and pictures”). Such a statement provides a clear definition of the term “media” that includes video, software, and pictures, in addition to audio. In addition to the express definition, Seet elsewhere indicates that its media includes video and other non-audio signals and databases. See, e.g., Ex. 1006 ¶¶ 26 (“if the media stream 102 is a video broadcast, each media item may comprise a television show or segment, an advertisement, or any other type of video”), 42–46 (creating databases of “videos,” “faces,” and “files”), 49 (“any signal that contains repeating content over any broadcast medium can benefit from the procedure described herein.”). Accordingly, the use of media in claim 9 for its claimed “media content database” and “media stream[s]” also includes both audio and non-audio media. The disclosure of the Seet provisional, however, is more limited and defines the term media exclusively as audio. Ex. 1019, 4 (“Media will be defined as any streaming audio source in any form, be it radio, television, cable, satellite, internet stream, or the like.”). This definition does not include the full scope of “media” as that term is used in claim 9 of Seet because it does not include video, software, and pictures.” slip op. at 14

“While Alden’s Figure 5 shows a sectional view of a segmented-headlight embodiment, thus depicting a single line of LEDs, that does not restrict the embodiment to a one-dimensional array. Indeed, Alden’s disclosures discussed above contradict such a view, as do the disclosures regarding Figure 5 and other segmented-headlight embodiments. We credit Petitioner’s expert’s testimony in this regard. Ex. 2041, 59:10–12 (“[I]t’s very clear we’re talking about a two-dimensional structure that is map of this set of slices in figure 5.”); accord id. at 56:25–60:18. The Figure 5 embodiment includes a switch array to control the individual lighting elements, with “[e]ach lighting element being independently controlled by a corresponding switch in an array of switches 115.” Ex. 1005 ¶ 29. The Figure 6 embodiment includes a face-on view of the headlight plainly showing a two-dimensional array, in addition to a sectional view similar to that of Figure 5. Id. at Fig. 6. And Alden describes that the Figure 6 embodiment uses a “switch array similar to 115 and the process previously described herein.” Id. ¶ 30. Considering Alden’s description of its sensing-and-control circuit in connection with Figure 3, which illustrates a two-dimensional array, and its description of Figure 5’s segmented headlight as working with that approach, we find that Alden’s LED-based segmented headlight is capable of selective illumination in two dimensions.

“B. Level of Ordinary Skill in the Art Factors pertinent to determining the level of ordinary skill in the art include (1) the educational level of the inventor; (2) the type of problems encountered in the art; (3) prior-art solutions to those problems; (4) the rapidity with which innovations are made; (5) the sophistication of the technology; and (6) the educational level of workers active in the field. Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). Not all factors may exist in every case, and one or more of these or other factors may predominate in a particular case. Id. These factors are not exhaustive, but merely a guide to determining the level of ordinary skill in the art. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). Moreover, the prior art itself may reflect an appropriate skill level. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Petitioner asserts that a person of ordinary skill in the art at the time of the alleged invention “would have had a bachelor’s degree in electrical engineering, mechanical engineering, computer science, or a similar field and two years of experience related to electronic consumer product design.” 3 The parties do not provide evidence or argument regarding objective indicia of nonobviousness. See, e.g., Pet. 9–93; Resp. 18–66. Pet. 6. Petitioner also asserts that an ordinarily skilled artisan “could have also obtained similar knowledge and experience through other means.” Id. Dr. Wolfe’s testimony supports Petitioner’s assertions. See Ex. 1003 ¶ 30. Patent Owner asserts that a person of ordinary skill in the art at the time of the alleged invention “would have had (1) a bachelor’s degree in electrical engineering, mechanical engineering, or a comparable field of study, and (2) at least two years of professional experience with electro-mechanical control systems, or other similarly relevant industry experience.” Resp. 3.

Above, we discussed issues concerning the “component” limitations in claims 1, 3, and 4 and an ambiguity in claim 4. See supra §§ III.C.4(c), III.C.5(c), III.C.6(c), III.C.7(c), III.C.8(c), III.C.9. We determine that no other claim language requires a discussion of scope or an explicit construction to decide whether Petitioner satisfies the “preponderance of the evidence” standard for proving unpatentability. D. Alleged Obviousness over Fukumoto: Claims 1–3, 7–9, and 17 Petitioner contends that claims 1–3, 7–9, and 17 are unpatentable under § 103(a) because the claims would have been obvious over Fukumoto.

“2. MEANS-PLUS-FUNCTION CLAIMING The patent statute provides that “[a]n element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.” 35 U.S.C. § 112 ¶ 6 (2006). The absence of the word “means” in a claim limitation creates a rebuttable presumption that § 112’s means-plus-function provision does not apply. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part). When a claim limitation lacks the word “means,” a party may rebut the presumption that § 112’s means-plus-function provision does not apply by demonstrating that “the claim term fails to ‘recite[] sufficiently definite structure’ or else recites ‘function without reciting sufficient structure for performing that function.’” Williamson, 792 F.3d at 1348 (alteration by the court) (quoting Watts v. XL Sys., Inc., 232 F.3d 877, 880 (Fed. Cir. 2000)). Construing a means-plus-function limitation involves two steps: first, identify the claimed function or functions; and second, determine what structure, if any, disclosed in the patent’s specification corresponds to the claimed function or functions. Williamson, 792 F.3d at 1351; see Medtronic, Inc. v. Advanced Cardiovascular Sys., Inc., 248 F.3d 1303, 1311 (Fed. Cir. 2001). For the second step, a person of ordinary skill in the art must “recognize the structure in the specification and associate it with the corresponding function in the claim.” All-Voice Computing PLC v. Nuance Commc’ns, Inc., 504 F.3d 1236, 1241 (Fed. Cir. 2007). The “duty to link or associate structure to function is the quid pro quo for the convenience” of using means-plus-function claiming. B.
