Petitioner also argues that “[a]dditional experience could substitute for a formal degree or formal training (and vice versa).” Id. Patent Owner proposes a slightly different level of skill, arguing that a person of ordinary skill in the art “would have had a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a comparable field and at least two years of experience related to 3D printing, with additional experience potentially being a substitute for a formal degree or training (and vice versa).” Prelim.

Iancu, 912 F.3d 1368, 1375 (Fed.

As for Patent Owner’s argument that Petitioner has failed to carry its burden to identify how the claims are to be construed, we disagree on the present record. Although Petitioner does not provide a preferred construction for the single term it proposes requires construction, Petitioner does identify which of its two alternative constructions applies to each of its asserted grounds of unpatentability. Pet. 6 (“Under the first construction, [the obviousness grounds] are applicable, and [the anticipation ground] would be excluded from the claim scope.

According to Patent Owner, because neither Mazumder nor Mori teaches visual comparison of image types, the idea to improve the Mazumder-Mori combination by simultaneously displaying different image types and thus permitting visual comparison must be driven by hindsight. Id. at 44–45. But Petitioner cites evidence other than the ’324 patent to support the person of ordinary skill in the art having a desire to visually compare the different images presented in the Mazumder-Mori combination. Pet. 23–24 (citing Ex. 1003 ¶ 113). Specifically, Dr. Wolfe testifies that “the presentation of the actual images captured by the camera and the virtual images simultaneously within the user interface would have beneficially aided the remote user to more easily visually compare the actual image and virtual image to quickly identify any defects or problems with the fabrication process” and that a person of ordinary skill in the art would have recognized this.

“limitation 1.2 because it is more consistent with the claim language and the specification of the ’416 patent. The language “each of the plurality of bits” clearly individualizes the “plurality of bits” and the language “indicates a respective time interval that physical shared channel resources are utilized to signal channels” clearly ascribes to each individual bit the function of identifying a time interval that is separate from the time interval(s) that the other individual bit(s) identify. Petitioner’s claim constriction argument largely ignores the words used in limitation 1.2. Petitioner fails to provide anything to explain how or why the plain meaning of “each” and “respective” in the context of limitation 1.2 could be understood by a skilled artisan to connote something other than the plurality of bits individually identifying a separate and distinct time interval (i.e., a “one-to-one correspondence”). Petitioner similarly does not identify anything from the specification of the ’416 patent that would support deviating from the plain meaning of limitation 1.2. And Petitioner’s reliance on 3M Innovative Properties appears to miss the mark. Pet. Reply 7. In that case, the Federal Circuit held that, when a claim term has an “ascertainable definition in the body of the claim,” their “cases do not support prescribing a more particularized meaning unless a narrower construction is required by the specification or prosecution history.” 3M Innovative Properties Co., 725 F.3d at 1329. Here, however, Patent Owner is not attempting to import a more particularized meaning into limitation 1.2, but to demonstrate that the ’416 specification is consistent with the ascertainable definition of “each” and “respective” within the context of limitation 1.2. In particular, Patent Owner highlights that the ’416 specification describes the resource allocation technique as using an indicator bit, within a plurality of indicator bits, that has a one-to-one correspondence to a specific time window established for a Forward Access Channel (FACH). See Ex. 1001, 13:63–14:25, 14:44–53, Figs. 7, 9; PO Resp. 11–14, 19–20; PO Sur-reply 2–3; Ex. 2001 ¶¶ 36–40, 49. And we agree that the ’416 specification informs, and is consistent with, the plain reading of limitation 1.2. See Ex. 1001, 13:63–14:25, 14:44–53, Figs. 7, 9. Therefore, we determine that the plain and ordinary meaning of limitation 1.2 requires all the plurality of bits to individually identify a separate and distinct time interval that physical shared channel resources are utilized to signal channels.” slip op. at 12

“PICH, which is communicated to Kim’s receiver, has a plurality of bits, the evidence fails to demonstrate sufficiently that each of those bits indicates a respective time interval that physical shared channel resources are utilized to signal channels, as limitation 1.2 recites. As Patent Owner correctly argues, the Vayanos paging indicators use multiple bits to indicate information about a single time interval in a frame, rather having several bits that individually identify a separate and distinct time interval. PO Resp. 39–41 (citing Ex. 2001 ¶¶ 67, 74–75). Vayanos teaches that “[t]he number of paging indicators (Np) in each PICH frame is configurable by the system and can take on a value of 18, 36, 72 or 144,” and that “[e]ach paging indicator is sent in 288/Np consecutive bits in the PICH frame, where 288/Np can take on a value of 16, 8, 4 or 2.” Ex. 1006, 3:26–34. As a result, if there are 18 (Np = 18) paging indicators, 288/NP = 288/18 = 16 (meaning that each paging indicator is 16 bits long), if there are 36 (Np = 36) paging indicators, 288/Np = 288/36 = 8 (meaning that each paging indicator is 8 bits long), if there are 72 (Np=72) paging indicators, 288/Np = 288/72= 4 (meaning that each paging indicator is 4 bits long), and if there are 144 (Np=144) paging indicators, 288/Np = 288/144 = 2 (meaning that each paging indicator is 2 bits long). Ex. 2001 ¶ 66. Each paging indicator (singular) taught by Vayanos includes multiple bits––each paging indicator (singular) has either 16, 8, 4 or 2 bits–– and Vayanos does not disclose or suggest a paging indicator that indicates a time interval with only a single bit. Id. And Petitioner does not cite Kim to show the number of bits used to indicate a time interval; only to show that a UE would receive broadcast information with paging information including paging indicators that identify a time interval in which physical shared channel resources are utilized to signal channels. See Pet. 40–49. Even accepting that the Kim/Vayanos combination discloses a UE receiving a paging indicator that is indicative of a time interval in which a Paging Channel PCH may be found or indicative of whether a frame will include a signaling channel (e.g., PCH) at a specific TTI within that frame, the combination does not disclose or suggest using a paging indicator that is a single bit indicating either of those time intervals. On the contrary, as noted above, Vayanos teaches that all paging indicators consist of multiple bits and, thus, the Kim/Vayanos combination discloses a UE that only receives and uses a plurality of bits to indicate a time interval that physical shared channel resources are utilized to signal channels. This is insufficient to show a reasonable likelihood that Petitioner will be able to establish that the Kim/Vayanos combination discloses or suggests receiving a plurality of bits wherein the individual bits each identify a separate and distinct time interval. Therefore, Petitioner has not shown sufficiently that the Kim/Vayanos combination discloses or suggests the subject matter limitation 1.2 recites. For the above reasons, we are not persuaded that Petitioner has shown sufficiently that the combination of Kim and Vayanos disclose or suggest broadcast information that includes a plurality of bits, wherein each of the plurality of bits indicates a respective time interval that physical shared channel resources are utilized to signal channels. This failing undermines Petitioner’s showing as to independent claims 1 and 7 (in the asserted Grounds 1 and 2) and, as a result, the same deficiency extends through to all of the dependent claims challenged in all of the grounds.4” slip op. at 18

Petitioner does not provide its own definition of the level of ordinary skill in the art. Instead, Petitioner asserts: In previous litigation involving the ’881 patent – the parent patent to the ’864 patent (Fuma International LLC v. R.J. Reynolds Vapor Company, Case No. 1:19-cv-260 (M.D.N.C. 2019)) with an identical specification – Patent Owner’s predecessor-in-interest asserted that a person of ordinary skill in the art (“POSITA”) at the time of the purported invention would have had a mechanical or electrical engineering degree, industrial design degree, or a similar technical degree, or equivalent work experience, and 5 to 10 years of experience in electromechanical devices. Ex. 1007, ¶¶14-17. Pet. 11–12; see also Ex. 1007 ¶ 16 (Mr. Sturges testifying that he meets “that qualification” without affirmatively providing a definition for a POSITA). Before institution, Patent Owner stated it did not challenge this definition (Prelim. Resp. 9), and we adopted Petitioner’s proposed definition in our Decision granting institution. During trial, Patent Owner also adopted this definition. PO Resp. 10–11. Upon a complete record, we see no reason to change and we maintain the agreed upon definition of a POSITA.” slip op. at 12

“Patent Owner argues, and Petitioner does not dispute, that an aperture is a “hole” or an “opening.” See, e.g., id. at 21; see generally Reply. Patent Owner asserts that, in the proper context, the plain and ordinary meaning of a housing having an aperture is that the aperture is a hole, or an opening, on the housing structure itself. Id. at 21–22. We agree. In order for an object to have an “aperture” or an “opening,” the aperture or opening must be on the structure itself and not on a separate object that is located in the structure. This construction is in accord with the Specification of the ’864 patent, which refers to apertures in context of the structure on which they are located. See, e.g., Ex. 1001, 6:12–18 (referring to a first end comprising a first aperture), 7:11–12, 7:65–67 (stating that the wall of an airflow passageway may have apertures).” slip op. at 18

“large obstructions that force the air flow to near the peripheral surface of the housing, render the passageway non-central. During prosecution of the ’864 patent, the Examiner rejected certain claims (i.e., dependent claims 49, 63, and 75) over Han. To overcome this rejection, the applicant argued that Han cannot meet the limitation “wherein the airflow passageway extends centrally and axially from the first aperture to the second aperture.” Ex. 1002, 273. The applicant explained that Han does not meet this limitation because Han’s shell (b) does not include a central airflow passageway and instead places the perforated component for liquid storage (9) in the middle of shell (b), thereby forcing the airflow around the peripheral surface of the perforated component for liquid storage (9). Id. at 273–274. The examiner relied on this argument in determining that the applicant had overcome an earlier rejection. Id. at 195. Thus, some obstructions of a passageway render the passageway non-central; in particular those obstructions that force air to flow near the peripheral surface of the housing are large enough to render the passageway non-central.” slip op. at 22

“lacks motivation and is plagued by improper hindsight.” Sur-reply 15–17. On the record developed during trial, we agree with Patent Owner that Petitioner has not shown by a preponderance of the evidence that a person of ordinary skill in the art would have had a reason to combine the teachings of Xia with those of Wang to arrive at the claimed limitations. Relying on the testimony of Patent Owner’s declarant Dr. Singhose, Petitioner argues that a person of ordinary skill in the art “would have known a central straight path has less airflow resistance than a circuitous one.” Reply 22 (citing Ex. 1035, 127:15–128:9). But the same witness also testified that higher airflow resistance might be desirable and explained that providing more resistance to airflow might result in improved mixing. Ex. 1035, 21:21–22:12, 127:20–24, 170:10–14. In addition, Dr. Singhose testifies that the complicated design of the airflow passageway in Xia “serves important functions,” including “allow[ing] large droplets to be reabsorbed by the liquid-guiding mechanism,” allowing “excessive liquid in the airflow [to] condense,” and “prevent[ing] the chemical liquid from being sucked into the mouth.” Ex. 2022 ¶ 190 (citing Ex. 1004, 11, 13–14, 16). Although Petitioner’s declarant Dr. Sturges testifies that a straight airflow passageway “would provide improved, smoother air flow,” he does not provide any evidence supporting the view that the air flow would be improved. Ex. 1007 ¶ 144. We credit the testimony of Dr. Singhose that using a straight passageway in Xia would have been detrimental rather than beneficial. Ex. 2022 ¶ 190. slip op. at 40

“Patent Owner argues, however, that this presumption is overcome in the present case, and we agree. PO Resp. 28–32. We note that, although the claims require the first aperture to be “on the first end,” the claims still require that the “housing hav[e] a first aperture.” Thus, the issue is whether the aperture must be on the housing itself or part of the housing, as well as whether the aperture is on the first end of the housing. Although “having” and “includes” are used with respect to the solution holding medium to refer to elements located inside the housing, the specification of the ’881 patent suggests that the ends of the housing are part of the housing itself, rather than located inside the housing. First, “the first end . . . can be integrated into a single assembly as part of the housing.” Ex. 1001, 6:16–17. Second, “the housing . . . may comprise the cylindrical wall and two end-caps,” or “the housing . . . may comprise the cartridge wall and a single end-cap.” Id. at 3:55–59. The only figures of the ’881 patent that depict first end 206 show it at the end of the housing rather than located within the interior of housing 202. Id. at Figs. 2, 3. Moreover, there is no requirement to construe a claim term uniformly across multiple uses in the claims when doing so would be nonsensical. Microprocessor Enhancement Corp. v. Texas Instruments, Inc., 520 F.3d 1367, 1375 (Fed. Cir. 2008). Here, construing a first element that is recited as “having” or “includ[ing]” a second element always as encompassing not only second elements that are part of the first element, but also second elements that are located within the interior of the first element, would lead to nonsensical results. Claim 2 recites an airflow passageway “having a length having a circular cross section.” Ex. 1001, 17:59–60. It would be nonsensical to interpret this claim as encompassing an airflow passageway of non-circular cross section that contains another object that has a circular cross section, and neither party argues in favor of such a reading. Similarly, claim 16 recites an “airflow passageway having an interior having a uniform cross-sectional area,” and there is no reason to interpret this claim as encompassing an airflow passageway of non-uniform cross-sectional area that contains another object that itself has uniform cross-sectional area. Id. at 19:47–48. Thus, the claims do not use “having” or “includes” consistently to refer to elements located within the interior of an object; instead, they sometimes use these terms to refer to elements that are a part of an object. See Epcon Gas Sys., Inc. v. Bauer Compressors, Inc., 279 F.3d 1022, 1030–31 (Fed. Cir. 2002) (terms should be construed based on the context of how the terms are used in the claims).” slip op. at 13

“Under the latest applicable guidance, Petitioner’s Sotera stipulation “is highly relevant, but [is] not . . . dispositive by itself.” CAPJ Memo at 2– 3. Accordingly, we consider Petitioner’s stipulation “as part of [our] holistic analysis under Fintiv.” Id. at 2. In theory, Petitioner’s stipulation could “mitigate[] any concerns of duplicative efforts between the district court and the Board, as well as concerns of potentially conflicting decisions” regarding unpatentability/ invalidity. Sotera, Paper 12 at 19. We note that Petitioner’s initial invalidity contentions included the two asserted references here, Bennett and Nashida. Although Petitioner served those contentions before the filing of the instant Petition—in which it proffered its stipulation—we cannot discern from the instant record whether Petitioner’s present invalidity positions in the underlying litigation incorporate any aspects of its grounds here based on Bennett and Nashida. Still, we view Petitioner’s stipulation as significantly mitigating potential conflict given the likelihood that the court would hold Petitioner (and its privies) to Petitioner’s representations made here.5” slip op. at 18

“controller” that “receive[s] an identifier for identifying a second video content from [an] external mobile terminal” and “acquire[s] the second video content via the internet using said identifier.” Ex. 1001, 20:29–31, 20:46–47, 20:52–55 (alterations and emphasis added). In the Bennett obviousness ground, Petitioner cites Bennett’s control signal that directs display of a video stream on a television screen for teaching the recited “identifier.” Pet. 32 (citing Ex. 1004 ¶ 32). Petitioner further cites Bennett’s teaching of an Internet server as a media source for teaching the “acquire[s]” limitation. Id. at 34 (citing Ex. 1004 ¶ 55). Petitioner alternatively cites its declarant’s testimony and contends that it would have been obvious “to use an identifier such as URL in Bennett’s system to retrieve video content from the Internet.” Id. at 35 (citing Ex. 1003 ¶ 87). Yet Patent Owner’s arguments (see Prelim. Resp. 59–64) call into question whether Bennett teaches or suggests the use of either Bennett’s control signal or a URL to “acquire the second video content via the internet.” In addition, we preliminarily agree with Patent Owner that Petitioner’s arguments regarding the URL “focus on justifying an example of what an identifier could be, and fail[] to address a scenario that would justify the receipt of a URL from a phone/remote” in Bennett’s system. Id. at 63. Petitioner’s further contentions for these limitations in the Bennett– Nashida obviousness ground (see Pet. 73–75) do not necessarily cure the deficiencies mentioned by Patent Owner. Petitioner contends that “Nashida discloses the use of identifiers, such as URLs, for retrieving internet content” and cites Nashida’s teaching of “‘controller 1010 transmit[ting] a command of requesting a transmission of a URL’ for retrieving and displaying web content on a display apparatus.” Id. at 73 (quoting Ex. 1005 ¶ 120). Yet, according to Patent Owner, Nashida appears to show the URL moving in the opposite direction of Petitioner’s intended mapping: “It is therefore the image display apparatus (the alleged ‘display apparatus’) that sends the URL to the remote controller . . . , and not the other way around, as claimed by Petitioner.” Prelim.
