“We question, therefore, whether someone having an education in textile engineering or physics, but no experience in the field of hunting blinds, would be consistent with the level of skill portrayed by the ’535 Patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We note that Petitioner’s expert’s experience, education, and qualifications are rooted in textiles, fibers and physics, and sophisticated subjects related thereto. See Ex. 1007 ¶¶ 14–20. But his deposition revealed that he has little or no experience in the field of hunting blinds. See Ex. 2038, 8–14.5 5 The same might be said of Patent Owner’s expert.

“1. Mesh Material In the Petition, Petitioner asks that “the term ‘mesh material’” be interpreted in accordance with “a plain and ordinary usage.” Pet. 25. Per Petitioner, the “plain and ordinary” meaning of the term “mesh material” is “a woven material of open texture with spaced holes therein.” Id. Per Petitioner, “[o]ther typical terms used to describe a mesh-like material” are “a screen material, or a netting material, which are believed to be synonyms.” Id. Patent Owner does not dispute that a mesh material would have an open texture with spaced holes therein. See PO Resp. 18. We find that Petitioner’s proposed construction aligns with the ’535 Patent’s specification. See Ex. 1001. The drawings in the ’535 Patent depict the mesh material 26 as having an array of uniformly spaced circular holes forming a net-like structure (see id., Fig. 1A, 1B, 4, 9) or an array of uniformly spaced rectangular openings (see id. Fig. 8) forming a screen-like structure. The embodiments of the mesh material 26 listed in the ’535 Patent (e.g., a mesh banner material, scrims, a network of fibers, etc.) are materials having net-like or screen-like structures.

“Our construction aligns with the claim language; Petitioner’s proposed construction does not. See Ex. 1001, 10:4–19. The independent challenged claims set forth “one or more panels of mesh material” and then set forth “said one or more panels comprising: a first side with a camouflage pattern; and a second side with a dark color coating.” Id. at 10:4–11. The recited “said one or more panels” corresponds to the previously recited “one or more panels of mesh material,” not panels comprising a material that was only a “mesh” prior to printing/coating. See id. Also, the independent challenged claims set forth that “the one or more panels of the mesh material define an outer surface of the camouflage structure.” See id. at 10:18–19, 1:23–24 (emphasis added). And the panel(s) defining a hunting blind’s outer surface would include the dark color coating. Our construction aligns with the ’535 Patent’s specification; Petitioner’s proposed construction does not. See Ex. 1001. The ’535 Patent repeatedly describes the relevant panel material in the hunting blind (i.e., post printing/coating) as a mesh material. See id., Abst., 1:19–5:34, 6:47–7:28, 9:16–54, Figs. 1A, 1B, 9. The ’535 Patent expressly describes and depicts the mesh material 26 as including the camouflage pattern and the dark-color coating. See id. at 1:52–56, 3:24–25, 3:31–33, Figs. 1A, 1B. The ’535 Patent says that “panels” of this coated mesh material 26 “are used to form” a hunting blind. Id. at 3:22–26. The ’535 Patent says that “[m]esh material is presented for a hunting blind with a camouflage pattern printed on a first side and a second side with a color coating.” Id. at Abst. The ’535 Patent says that “mesh material of interwoven fabric is provided for a hunting blind including a camouflage pattern printed on a first side and a second side with a dark color coating.” Id. at 1:19–22; see also id. at 1:44–49. Our construction aligns with the ’535 Patent’s prosecution history; Petitioner’s proposed construction does not. See Ex. 1006. As mentioned above, throughout prosecution of the ’535 Patent, the same prior art material was mapped to the claimed panel(s) of mesh material. See Ex. 1006, 64–72, 122–106. The mapped-to prior art mesh material was described during prosecution as an “interwoven fabric” with “a pattern” printed on a first side and “a dark color coating” on a second side. Ex. 1006, 64; see also id. at 122. And the mapped-to prior art mesh material (i.e., which included not only the interwoven fabric but also the printed pattern and the dark color coating) had a “net-like structure” with an array of uniformly spaced “net holes” that are “not closed.” Ex. 2021, 4:1–5, see also id. at 2:58–3:6, 4:34–45, Figs. 1, 2a.

“However, Patent Owner does not bear the burden of proving Strength’s camouflage material 10 does not have holes. Rather, Petitioner bears the burden of proving that Strength’s camouflage material 10 does have holes. And Petitioner’s arguments that undermine Patent Owner’s position that Strength’s camouflage material 10 does not have holes, concurrently undermine Petitioner’s position that Strength’s camouflage material 10 does have holes. Per Petitioner, “Strength is silent on whether visible holes exist in the fabric” (Pet. Reply 8) and “the Strength reference doesn’t discuss anything about holes” (Tr. 14). Petitioner’s expert testified that it was his “understanding that Strength is silent” on “whether or not there are holes.” Ex. 2038, 44. Petitioner contends that Strength’s silence about the presence/ absence of holes hinders Patent Owner from proving that Strength’s camouflage material 10 does not have holes. See Pet. Reply 8.

“A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains.

“Relying on the declaration testimony of Dr. Abraham, Petitioner contends that an ordinarily skilled artisan for the ’681 patent “would have been knowledgeable regarding liquid cooling systems for computer systems, would have earned at least a bachelor’s degree, such as an B.S. (bachelor of science), or equivalent thereof, in electrical or mechanical engineering or a closely-related field, and would have possessed at least two or three years of experience in liquid cooling systems for computer systems, or in similar systems.” Pet. 17. Petitioner additionally contends a “person with less education but more relevant practical experience, depending on the nature of that experience and degree of exposure to liquid cooling systems for computer systems, could also qualify as a POSITA in the field of the ’681 patent.” Id. (citing Ex. 1005 ¶ 42). Patent Owner does not address the level of skill of the ordinary artisan. See generally Prelim. Resp. Based on this record, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’681 patent and the asserted prior art, and we apply it in our obviousness evaluations below.

“Petitioner asserts that a person of ordinary skill in the art “at the time of the alleged invention would have had a master’s degree in Aerospace or Naval Engineering, or equivalent experience, and one to two years of experience in the field of watercraft design and construction.” Pet. 24–25 (citing Ex. 1002 ¶ 20). Dr. Brizzolara’s cited testimony is somewhat different than what is asserted by Petitioner. Dr. Brizzolara’s testimony adds that the “one or two years of experience in watercraft design and construction” would have been “particularly as that design and construction is related to personal watercraft design and construction and/or hydrofoil design and construction.” Ex. 1002 ¶ 20. Dr. Brizzolara also testifies: This level of skill in the art is appropriate because concepts of hydrofoil design and construction along with appropriate fluid dynamics to teach the skills necessary to design and construct hydrofoil-based watercraft are taught in master’s level courses. These concepts that would be understood would include academic teaching of flight dynamics utilizing well known texts (such as Etkin, B., & Reid, L. D.

“stage, the petition must identify, with particularity, evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent and therefore that there is a reasonable likelihood that it qualifies as a printed publication.” Hulu, LLC v. Sound View Innovations, LLC, IPR2018-01039, Paper 29 at 13 (PTAB Dec. 20, 2019) (precedential). Thus, we address this issue presented by Petitioner. The determination of whether a document is a “printed publication” under 35 U.S.C. § 102 “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” In re Klopfenstein, 380 F.3d 1345, 1350 (Fed. Cir. 2004). “Because there are many ways in which a reference may be disseminated to the interested public, ‘public accessibility’ has been called the touchstone in determining whether a reference constitutes a ‘printed publication.’” Jazz Pharm., Inc. v.

See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

More particularly, and as discussed below, Petitioner does not show sufficiently how the prior art teaches the structure identified as corresponding to the alleged claimed function. Further, because we deny on the merits (as discussed below), we do not address Patent Owner’s alternative argument that we should deny institution because “Petitioner fails to construe th[is] limitation and otherwise argues for an advisory opinion from the Board on indefiniteness.” Prelim.

Limitation 6k recites “a first position, a second position, and a third position defined by the adjustable child carrier.” Id. at 18:36–37 (emphasis added). Patent Owner proposes a construction for “defined by” in these limitations. See Prelim. Resp. 12–15.

“Public accessibility “has been called the touchstone in determining whether a reference constitutes a ‘printed publication’ . . . .” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1348 (Fed. Cir. 2016) (quoting In re Hall, 781 F.2d 897, 898–99 (Fed. Cir. 1986)). In Hulu, the Precedential Opinion Panel (“POP”) rejected a petitioner’s argument that a reference necessarily meets “the reasonable likelihood standard for institution where the reference bears conventional markers of publication, such as a copyright date, edition identifiers, publication by a commercial publisher, and the assignment of an ISBN number.” Hulu, Paper 29 at 17. The POP stated: “We do not hold that any particular indicia per se is sufficient at the institution stage. Rather, the indicia on the face of a reference, such as printed dates and stamps, are considered as part of the totality of the evidence.” Id. at 17–18 (citing Nobel Biocare Servs. AG v. Instradent USA, Inc., 903 F.3d 1365, 1377 (Fed. Cir. 2018)). Here, Petitioner provides no citation, no discussion, and no support for its assertion that the Synergy Manual was “published” in “2007.” See Pet. 2. Instead, we are left to assume that Petitioner relies on the text “© BabyBjörn AB, Stockholm, 2007” at the bottom of page 6 of the Synergy Manual. More to the point, Petitioner does not discuss in the Petition any evidence supporting the implicit position that the Synergy Manual was publicly accessible prior to the critical date of the claimed invention.” slip op. at 13

“Petitioner asserts that a person of ordinary skill in the art would have had an undergraduate degree in mechanical or electrical engineering or physics, plus 2–3 years of experience in LiDAR design. Pet. 3 (citing Ex. 1003 ¶¶ 72–77). Patent Owner argues that a POSITA would have had an undergraduate degree in mechanical or electrical engineering and two to three years of work experience with electro-optical and electro-mechanical devices or systems, with, at a minimum, at least one year of work experience was with LIDAR designs, where less work experience may be compensated by a higher level of education or vice versa. PO Resp. 4 (citing Ex. 2009 ¶ 60). We agree with and will apply Patent Owner’s statement of the level of ordinary skill in the art. This level of ordinary skill is reflective of the education and experience that would have been required to understand the problems and solutions identified in the ’381 patent and the prior art.

“The term “coincident with” as used in the ’381 patent does not require perfect coincidence. To explain why, we provide an annotated version of Figure 2 of the ’381 patent below. In Figure 2 above, the rays of electromagnetic radiation indicated in red originate from illumination source 111, but they are not coincident with the corresponding aperture’s field of view, and instead they are absorbed or blocked by the aperture layer’s stop region. Ex. 1001, 3:61–4:5. As Figure 2 shows, out of five ray lines emitted by illumination source 111, only three are within its corresponding aperture’s field of view. This conveys an understanding that “coincident with” does not require perfect matching of the discrete spot of radiation from the illumination source and the aperture’s field of view.” slip op. at 14

“We begin with the language of the claims. The claims merely require that the “plurality of pixels are arranged in a second arrangement, proportional to the first arrangement.” Ex. 1001, 17:30–31. There are no other specific requirements about “first arrangement” or the “second arrangement” and no specific requirement about what kind of “proportional[ity]” is required. Thus, the language of the claims does not provide a basis for Patent Owner’s narrow reading, nor does it necessarily preclude it.” slip op. at 19

“Petitioner identifies multiple reasons to make this combination. First, with respect to Higashi’s bandpass filter, Petitioner argues that “a POSITA would have been prompted to implement Imai’s system to include a bandpass filter for the received light (as suggested by Higashi) so as to advantageously pass through only light of the operational wavelength of the corresponding laser emitter and ‘eliminate the effect of background light.’” Id. at 60 (citing Ex. 1011 ¶ 86; Ex. 1003 ¶ 256). Petitioner contends that “the resulting combination would advantageously filter out interfering light sources along the optical path of each of the detector pixels, thereby improving accuracy, improving the signal-to-noise ratio, and reducing the likelihood of false detections at the detector pixel.” Id. at 61. Second, Petitioner argues that “a POSITA would have been motivated to arrange multiple SPADs in each of Imai’s detector pixels (e.g., pixels 1- 16 in Imai’s FIG. 11) so that “erroneous detection of pixels[] can be reduced” and improved accuracy is achieved.” Id. (citing Ex. 1011 ¶ 71–72; Ex. 1003 ¶ 257; Ex. 1009 ¶ 48). Third, Petitioner contends that using Higashi’s multi-SPADs in Imai’s detector pixels would have led to uninterrupted performance when an individual diode is quenched, and would have furthered Imai’s objective of “inhibiting the increase of detection obtaining time” because multi-SPADs facilitate high speed data processing as they can take turns to receive the incoming photons. Id. (Ex. 1009 ¶¶ 6–7; Ex. 1011 ¶¶ 71, 72; Ex. 1027 ¶¶ 3– 4; Ex. 1003 ¶ 258). Fourth, Petitioner asserts that the combination “was simply the” slip op. at 45

“Petitioner contends that multiple reasons would have prompted a POSITA to combine Grzesik’s cross talk absorption layer (corresponding to the claimed “aperture layer”) in the Imai-Higashi combination. Pet. 51–53. First, Petitioner contends that implementing Grzesik’s absorption layer in the Imai-Higashi combination would reduce cross talk consistent with Imai’s objective of improving resolution by allowing for more pixels to be used in a specified detection area. Id. at 51–52 (citing Ex. 1012, 4:65–5:6, 5:11–32; Ex. 1009 ¶¶ 6–7; Ex. 1003 ¶¶ 212–213). Second, Petitioner asserts that the combination would have been prompted as “the application of known techniques (Grzesik’s suggested improvement for a cross talk absorption layer to reduce secondary detection) to a known system (the primary Imai LiDAR system) ready for improvement to yield predictable results (benefits articulated above).” Id. at 52 (citing KSR, 550 U.S. at 417). Petitioner asserts that “a POSITA would have had a reasonable expectation of success at adapting Grzesik’s cross talk absorption layer to the scanning laser radar of the Imai-Higashi combination.” Pet. 52 (citing Ex. 1003 ¶ 214). Specifically, Petitioner contends that “Grzesik demonstrates the known benefits of implementing a cross talk absorption layer disposed on the detector array, with apertures of the cross talk absorption layer aligned with individual detectors, and describes using its cross talk absorption layer on Geiger-mode APDs (e.g., SPADs) as used by the Imai-Higashi combination.” Id. at 52–53 (citing Ex. 1003 ¶ 214). Patent Owner does not dispute Petitioner’s contentions concerning the motivation to combine Imai, Higashi, and Grzesik, or the reasonable expectation of success a POSITA would have had in making the combination. Petitioner shows by a preponderance of the evidence that a POSITA would have been motivated to combine Imai, Higashi, and Grzesik with a reasonable expectation of success.” slip op. at 39
