See supra §§ III.D.4(a)–(d). Additionally, Petitioner provides reasons with rational underpinnings as to why an ordinarily skilled artisan would have been motivated to combine the teachings of Gai, Yip, and Kwan in the way Petitioner proposes and would have had a reasonable expectation of success. See supra § III.D.4(e). Hence, Petitioner demonstrates a reasonable likelihood of proving that claim 1 is unpatentable under § 103(a) because the claim would have been obvious over Gai, Yip, and Kwan.” slip op. at 34

We do not agree with Patent Owner that Petitioner does not present a coherent theory for how Agee teaches or suggests the subject matter of limitations [1.3]–[1.6]. Although we recognize that the Petition provides discussions on alternative disclosures in Agee, we determine that the Petition sufficiently presents a theory that coherently treats the subject matter of limitations [1.3]–[1.6].

As Petitioner contends, signals transmitted from Agee’s remote station include a pilot signal. Pet. 52. These signals are simultaneously sampled at multiple antenna elements. Id.” slip op. at 24

“A wave interacts with two different antenna elements simultaneously, where the phase and amplitude (signal strength) of the wave is different at each antenna element. Id. ¶¶ 333–336 (cited at Pet. 10–11). We reproduce Dr. Mahon’s figure illustrating this point below. Id. ¶ 336. Dr. Mahon explains that at a given sampling instance, the wave is in the process of propagating across the antenna array and antenna A detects the signal when it is at phase 45 degrees and detects a signal strength of around 0.7 (sin(45°)). Antenna B is physically located such that (sampling at the same time as Antenna A) it detects the same signal at phase 270 degrees and will measure a received signal strength of -1.0 (sin(270°)). If the array summed those two values, the output of the array would in this case be sin(45°) + sin (270°) = 0.7 + -1.0 = -0.3 which is much less than the value at antenna A (0.7) without summation. However, if the sample value at antenna B is adjusted by the “phase shift” or “phase difference” between A and B (i.e., 235°), the sum would be sin(45°) + sin (270° - 235°) = 0.7 + 0.7 = 1.4, which is twice as large as the value at antenna A (0.7) without the coherent summation. Id. ¶ 337. Dr. Mahon testifies that “[t]he Butler matrix purposefully uses these different phases detected simultaneously by the antennas.” Id. ¶ 338. Dr. Mahon explains that the different signal strengths at different antenna elements are measured, and “[t]hese measurements are passed into the circuitry of [phase] shifters and dividers / combiners.” Id. ¶ 342 (included in the Petition at Pet. 14). On the limited record before us, we credit Dr. Mahon’s testimony, for at least the reason that it is consistent with our understanding of Exhibits 1001, 1004, and 1005.” slip op. at 25

But Patent Owner and Dr. Howell do not explain how a barcode could be used in the devices depicted in Figures 16–18, which place the detection means 2.4.2 on the outer circumference of the flange (not its underside) and rely on toothed-rings physically interacting with either the chamber, retaining arms, or a pinion. Ex. 1047, 12:22–31, 13:8–18. Indeed, the second German priority application explains that means 2.4.2 physically interacts with retaining arms 30 (embodiments of Figures 16 and 17) or a pinon (embodiment of Figure 18), and if means 2.4.2 were not present in these embodiments the capsule would either “drop through into a waste container” or could not be inserted through the insertion shaft. Id. at 12:22– 27, 13:9–12, 13:16–35 (noting that in the embodiment disclosed in Figure 18 a pinon interacts with means 2.4.2 and only when means 2.4.2 “is formed complementary to the teeth of the means” can the capsule be inserted). At no point does the second German application identify means 2.4.2 as a barcode or suggest a barcode could be used as the detection means. The second German application also states that A person skilled in the art is also aware that for example the insertion shaft may also contain a sensor, for example a camera, clear, however, that element 27 is part of the brewing chamber, and not the capsule. Ex. 1047, 12:27–31, 13:5–8, 13:21–26, 15:36. Thus, we are not persuaded that the toothed ring is in fact on the bottom side of the flange. which senses the shape of the means 2.4.2. For example, it would be possible, in the present case, for the shape of the teeth and/or the spacing between the same to be sensed. This signal, in turn, is passed to a control means, which frees, for example, the brewing chamber if the capsule is the correct one. Ex. 1047, 14:11–19. Again, despite using a camera to determine if a capsule is “the correct one,” the second German application does not suggest using a barcode in place of the toothed-ring structure, or suggest moving the location of the detection means 2.4.2 from the outer surface to the underside of the flange.

Conversely, Dr. Howle has limited experience in this field and is not one of ordinary skill in the art. Although Mr. Jobin’s testimony is more persuasive regardless of the discrepancy in experience between the two declarants, when this difference in design experience is considered, it only serves to increase the weight we give to Mr. Jobin’s testimony. there is a “snug fit” to avoid “unbalances.” PO Sur-reply 8 (citing Ex. 1004 ¶¶ 205, 479, 484, 507, 512).

Patent Owner’s assertion that Yoakim discloses the use of certain capsules that might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point.

We credit the testimony of Mr. Jobin that a person of ordinary skill in the art would have sought to place the code at the bottom of the flange and would have had a reasonable expectation of success in so doing. Ex. 1003 ¶ 184. For reasons explained above, we assign little or no weight to Dr. Howle’s conflicting testimony because he has little or no experience designing a mechanical beverage system or similar product. See supra 10– 16. Petitioner lays out persuasive reasons why Dr. Howle’s testimony, on this particular point, is “conclusory” and rests on “bodily incorporation” of the references. Reply 24; see id. at 22–24 (pointing out with particularity fundamental flaws in Dr. Howle’s opinions); In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“It is well-established that a determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements.”); In re Nievelt, 482 F.2d 965, 968 (CCPA 1973) (“Combining the teachings of references does not involve an ability to combine their specific structures.”). In addition, Patent Owner contends that Yoakim requires that the capsule holder be capable of receiving a set of multiple volume capsules and that there is a “snug fit” to avoid “unbalances.” Sur-reply 8 (citing Ex. 1004 ¶¶ 205, 479, 484, 507, 512). According to Patent Owner, Petitioner does not explain adequately how the use of Jarisch’s “straight chamber” with a capsule holder that does not engage with the side wall of the capsule would allow insertion of multiple volume capsules or permit a “snug fit” in the modified device of Yoakim. Id. at 8–9. Patent Owner’s view that Yoakim discloses the use of certain capsules which might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point. Petitioner is not seeking a bodily incorporation of Yoakim and Jarisch and, in any event, other embodiments of Yoakim do not require the type of flared capsule identified by Patent Owner. Ex. 1004, Fig. 63. Furthermore, we credit the testimony of Mr. Jobin that one of ordinary skill in the art would have understood how to design the chamber of Yoakim to allow reading of a barcode on the underside of the flange. Ex. 1003 ¶¶ 187–195. With respect to the argument that the use of Jarisch’s design would not allow a snug fit, we are directed to no persuasive evidence that Jarisch’s lack of contact between the capsule side wall and the holder would render the device inoperable or less effective. Resp. 39–40; see Reply 22 (citing Ex. 2019, 36:18–37:6). Indeed, as Petitioner points out, Jarisch indicates that its device, including its capsule holding means, allows the capsule to be successfully driven in rotation.

“Prelim. Resp. 23 (citing Ex. 1013, 37) (annotated in red by Patent Owner). IEEE-802.16’s Table 5 shows that the CID is a field of a generic MAC header. Petitioner does not show sufficiently that the CID, located in the header, specifies content payload of a MAC message, as required by limitation 1A.

“Claim 1 describes gel spinning as the manner by which the filaments comprised in the claimed colored multi-filament yarn are obtained. This, on its face, is a product-by-process claim element because it describes the filament structure being obtained in a particular way, i.e., by gel spinning. See Kamstrup A/S v. Axioma Metering UAB, 43 F.4th 1374, 1382 (Fed. Cir. 2022) (agreeing with the Board that “cast in one piece” is a product-by-process claim element as it describes the structure being cast “in a particular way”). For this element to be limiting, it must impart “structural and functional differences” that distinguish the claimed product from the prior art. See Amgen Inc. v. F. Hoffman-La Roche Ltd, 580 F.3d 1340, 1365–67 (Fed. Cir. 2009). Patent Owner argues persuasively that gel spinning imparts structural and functional differences to the claimed product because the process “creates overlap between polyethylene molecules within the UHMWPE filaments that maximizes the intermolecular Van der Waals interactions, resulting in highly crystalline filaments with high tensile strength.” Prelim.
