“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

“Under the approach described in Alice and further explained in Enfish, Internet Patents, and Electric Power Group, we are persuaded by Petitioner’s argument and evidence that claims 1 and 11 are directed to an abstract idea. As discussed above, Petitioner has shown that the claims recite a process to “collect, store, and process information about consumer memberships, merchants, manufacturers, and sales transactions” (Pet. 34), a process that qualifies as an “abstract idea” (id. at 71) of “conventional information processing” in the retail industry (id. at 72), for which conventional components, such as a magnetic stripe scanner, computers, and databases, are merely invoked as tools used in their ordinary and conventional manner (Pet. Reply 8–11). In Electric Power Group, the Federal Circuit explained that the “the realm of abstract ideas” includes “collecting information, including when limited to particular content.” Elec. Power Grp., 830 F.3d at 1353. The court determined, therefore, that the claims at issue were directed to an abstract idea because “the focus of the asserted claims” is “on collecting information, analyzing it, and displaying certain results of the collection and analysis.” Id. We are persuaded that claims 1 and 11 in this case are similarly directed to an abstract idea because Petitioner’s argument and evidence shows that the focus of the claims, the claims’ “character as a whole,” is on conventional information processing in the context of membership discount programs that use generic computers and conventional devices as tools to provide discounts without coupons.” slip op. at 18

“As an initial matter, Patent Owner asserts that Petitioner has not met its burden of proof because Petitioner relies only on the ’115 patent and its prosecution history to argue unpatentability and does not present any other evidence, such as a witness. PO Resp. 6–7, 13–20. Patent Owner argues that Petitioner has presented no evidence of unpatentability because the ’115 patent and its file history “shows the Patent Owner has a valid, issued patent and nothing more.” Id. at 7. We are not persuaded because, as discussed below, in this case we need to look only to the ’115 patent and its prosecution history to support a finding of unpatentability under §§ 101 and 112. See In re TLI Comm. LLC Patent Litig., 823 F.3d 607, 613–14 (Fed. Cir. 2016) (the patent alone is sufficient to sustain a finding of unpatentability under § 101).” slip op. at 12

“with the Supreme Court and Federal Circuit precedents on step one analysis under the Alice framework. In step one of the Alice analysis, to determine whether the challenged claims are directed to an abstract idea, the inquiry is to ask, considered in light of the Specification, whether “their character as a whole” is directed to an abstract idea, not, as Patent Owner contends, identifying the “core invention” of the patent. See Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1335 (Fed. Cir. 2016) (quoting Internet Patents Corp. v. Active Network, Inc., 790 F.3d 1343, 1346 (Fed. Cir. 2015)). Relying on the distinction made in Alice between, on one hand, computer-functionality improvements and, on the other, uses of existing computers as tools in aid of processes focused on “abstract ideas,” the court in Enfish clarified that a relevant inquiry in step one of the Alice framework is to ask whether the “focus” of the claims is on the specific asserted improvement in computer capabilities or, instead, on a process that qualifies as an “abstract idea” for which computers are invoked merely as a tool. Enfish, 822 F.3d at 1335–36 (citing Alice, 134 S. Ct. at 2358–59). In this inquiry, claims “directed to an improvement in the functioning of a computer” are contrasted with claims “simply adding conventional computer components to well-known business practices” or “generalized steps to be performed on a computer using conventional computer activity.” See TLI, 823 F.3d at 612 (quoting Enfish, 822 F.3d at 1338). The Federal Circuit further clarified recently and described the first-stage inquiry as “looking at the ‘focus’ of the claims, their ‘character as a whole.’” Elec. Power Grp., LLC v.

“claims fail to recite any elements that individually or as an ordered combination transform the abstract idea of collecting and correlating information to provide personalized nutritional information of food products to shoppers into a patent-eligible application of that idea. It is well-settled that mere recitation of concrete, tangible components is insufficient to confer patent eligibility to an otherwise abstract idea. TLI, 823 F.3d at 613. Rather, the recited components must involve more than performance of “‘well- understood, routine, conventional activit[ies]’ previously known to the industry.” Alice, 134 S.
