“The level of skill is uncontested. Patent Owner adopts the level of skill identified by Petitioner as: [at] the time of the alleged invention in 2018, a POSITA[2] would have had a B.S. degree in mechanical or petroleum engineering or a similar technical discipline, with at least five years of experience in oil or gas well drilling, completion, and/or subsurface production operations or in technical support of such operations including at least some experience in unconsolidated formations utilizing sand control methods and means.

“on embodiments of Yeh with concentric sand screens having nine shunt tubes (six transport tubes and three packing tubes) (Yeh Figures 4A–B) and eccentric sand screens with four shunt tubes (two transport tubes and two packing tubes) (Yeh Figures 8A, 8C). See Pet. 32–37, 39, 41–43. Yet, Petitioner’s reasoning as to why “a higher-pressure shunt tube assembly necessitated greater wall thickness” rests on an unspoken one to one comparison between the shunt tubes of the different systems. See id.; see also Ex. 1003 ¶¶ 291–297 (Petitioner’s declarant comparing possible transport tubes of different pressure regions without considering or addressing any difference in the number of transport tubes). However, the embodiments relied on by Petitioner have different numbers of shunt tubes, and thus the greater wall thickness does not appear to be “necessitated” in the way inferred by Petitioner. Further, Petitioner’s analysis would seem to be most appropriate when comparing two concentric sand screens for different pressure regions, or two eccentric sand screens for different pressure regions. relies on Yeh’s teachings related to a horizontal well bore of 5000 feet for the “concentric screen → crossover tool → eccentric screen” arrangement, as well as, for why the concentric screen needs to be rated for a high pressure. Pet. 32–37, 39, 41–43. Petitioner also refers to these features for why one of skill in the art would combine the teachings of Yeh and Yeh2. Id. at 32. However, on cross-examination, Petitioner’s declarant agreed that it is concentric sand screens having a 6x3 shunt tube design that would provide the noted benefits of being rated for a higher pressure and being more robust (as relied on in the Petition), as compared to eccentric sand screens. Ex. 2013, 42:20–43:8; Sur-reply 4–5. This also exposes another issue with Petitioner’s arguments. Though Petitioner identifies that one of skill in the art would be aware that material choice, wall thickness, and pipe diameter all impact burst pressure of a pipe (Pet. 42 (citing Ex. 1017, 24 (Equation (14))), the Petition essentially ignores the fact that the claims do not require a single pipe in isolation. The claims require two shunt tube assemblies, each surrounding a base pipe within a wellbore. It is uncontested that a wellbore provides a confined space for such a system and thus any change in wall thickness of one pipe can result in a significant impact in the function of the other pipes. We find the testimony of Petitioner’s declarant (see, e.g., Ex. 1003 ¶¶ 290–297) unpersuasive when discussing wall thickness because it focusses on basic considerations of a standalone pipe, without sufficient consideration of the claimed completion assembly with its required pipe and tube structure. PO Resp. 20–26.” slip op. at 17

“In response to Patent Owner’s argument concerning Yeh’s embodiments relied on in the Petition, Petitioner argues for the first time that Patent Owner’s declarant “conceded, Yeh discloses that both concentric and 47:19–48:21). Petitioner does not provide a citation to Yeh or a citation to where the Petition relies on the same number of shunt tubes between concentric and eccentric screens. The deposition cited by Petitioner discusses Yeh at column 16, lines 26 through 35. However, the Petition does not cite or rely on these teachings of Yeh. Thus, we decline to consider this late argument.4 See 35 U.S.C. § 312(a)(3) (requiring the petition to identify “with particularity . . . the grounds on which the challenge to each claim is based, and the evidence that supports the grounds”); 37 C.F.R. § 42.104(b)(5).” slip op. at 18

“Thus, we agree with Petitioner that the combination of Yeh and Yeh2 teaches determining the shunt tube system operating pressures associated with the distal end of the production zone, but also more generally, determining the operating pressures along the entire production zone. With this knowledge of the system operating pressures, Petitioner argues that one of skill in the art would have selected eccentric screens for the distal end of the production zone “at any point at which the slurry pressure dropped below the pressure capacity of the eccentric screen shunt tubes.” Pet. 66 (citing Ex. 1005, 30:16–20; Ex. 1003 ¶ 388). In other words, knowing that the pressure decreases as you approach the toe, Yeh’s low-pressure rated eccentric screens could be used from some point prior to and covering the toe. determined pressure.” PO Resp. 37–38. We disagree. As discussed above, the record supports Petitioner’s position that one of skill in the art would have “understood the need to determine the shunt tube system operating pressure throughout the horizontal wellbore.” Ex. 1003 ¶ 383; see also Pet. 64–65. We find convincing Petitioner’s argument that one of skill with this understanding of the system pressures would select a shunt tube system rated to not only address the distal end, but also to address the needs of the adjacent region, so long as the pressure rating supported such a selection. See Pet. 65–67; Ex. 1003 ¶¶ 385–388.” slip op. at 22

“does not remove the claim from the realm of abstract ideas. See Pet. 52–53; Reply 12; SAP Am., Inc. v. InvestPic, LLC, 898 F.3d 1161, 1168 (Fed. Cir. 2018) (holding that it “does not matter to [the conclusion that the claim is directed to an abstract idea] whether the information here is information about real investments,” as “even if a process of collecting and analyzing information is ‘limited to particular content’ or a particular ‘source,’ that limitation does not make the collection and analysis other than abstract” (citation omitted)). Further, the last two clauses of claim 1 that recite how the transaction is viewed from the perspectives of the participant and vendor system, respectively, merely express the “non-physical result” of the information transfers and confirm the abstract nature of the claimed subject matter. See Pet. 57. In fact, as to the vendor system clause, the Specification indicates that the vendor system transfers information no differently than it would for any other transaction. See Ex. 1001, col. 7, ll. 15–18 (disclosing that vendor system 208 responds to purchase request 216 “in the same way that it would respond to any other purchase request from a consumer that presents a credit card”).” slip op. at 35
