“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.

“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 Patent Owner points out, Petitioner has oversimplified the challenged claims. Prelim. Resp. 31. The challenged claims are not directed simply to the idea of providing money to an account holder or using trial-and-error until success is achieved. Rather, the claims are directed to particular methods of providing money to an account holder using an ATM via a POS transaction after an ATM transaction has failed. See Alice, 134 S. Ct. at 2354 (“Applications of such concepts to a new and useful end . . . remain eligible for patent protection.”) (internal quotation marks and brackets omitted). Further, Petitioner’s analysis omits any consideration of the elements of the claims as ordered combinations to determine whether the additional elements transform the nature of the claims into a patent-eligible application. It was Petitioner’s burden to do so. Petitioner has not shown that the claims are more likely than not patent-ineligible. Alice, 134 S.

- Novelty / Anticipation (§102) › Anticipation standard (single reference, every element)Not shown unpatentableNot shown unpatentable
“It is a petitioner’s burden to explain how a challenged claim should be construed and how, being so construed, it is unpatentable. 37 C.F.R. § 42.204(b)(3)–(4). Petitioner does not propose an express construction for “personal identification number” and does not show that its plain and ordinary meaning would include a password. Further, claim 1 requires entering a PIN into the terminal. In the context of the specification and surrounding claim language, this step is part of the claimed “method of providing money or an item of value to an account-holder.” The teaching on which Petitioner relies, however, relates to a system operator’s back-end access of the Akel system. See Ex. 1006, 6:58–62 (“Each system operator requires a password to access the system . . . .”) (emphasis added). Elsewhere, Akel describes a “customer” (distinct from a system operator) as using a kiosk to obtain cash. Id. at 2:56–3:11. But, Akel does not describe entering a password into a terminal, let alone a PIN, as part of that process. Thus, even if Akel’s password fell within the scope of the recited PIN, the Petition would still fail to show how its use by an operator “to access the system” (see Ex. 1006, 258–60) meets the recited “entering a personal identification number into the terminal” as part of the claimed “method of providing money or an item of value to an account-holder.” Petitioner has not shown that Akel teaches “entering a personal identification number into the terminal.” Accordingly, Petitioner has not shown that claim 1, or dependent claims 2–8, are more likely than not anticipated by Akel.” slip op. at 13

“The invention date of the ’792 patent is no later than its filing date, which is January 5, 1998. Although the Reeder application was filed, and thus privately known to Mr. Reeder, before the ’792 filing date, such private knowledge is not within the scope of § 102(a). See, e.g., Carella v. Starlight Archery & Pro Line Co., 804 F.2d 135, 139 (Fed. Cir. 1986) (“The statutory language, ‘known or used by others in this country’ (35 U.S.C. § 102(a)), means knowledge or use which is accessible to the public.”).

Because the application from which the ’792 patent issued was filed before that date, our citations to 35 U.S.C. § 102 are to its pre-AIA version. eventually patented of course but not until after the filing date of the ’792 patent. For these reasons, Reeder is not prior art under 35 U.S.C. § 102(a), which is the only provision under which the Petition asserted Reeder. Reeder presumptively is prior art to the ’792 patent under a different subsection of the statute, namely § 102(e). However, a reference that is prior art under only § 102(e) may not be asserted in a CBM patent review. Under the AIA, a Petition for a CBM patent review may challenge novelty or non-obviousness of a claim only on the basis of: (i) prior art that is described by section 102(a) . . . ; or (ii) prior art that— (I) discloses the invention more than 1 year before the date of the application for patent in the United States; and (II) would be described by section 102(a) . . . if the disclosure had been made by another before the invention thereof by the applicant for patent. AIA § 18(a)(1)(C). Because Petitioner has not shown that Reeder is prior art that may be asserted in a Petition for a CBM patent review, all of the grounds that rely on Reeder are denied.” slip op. at 15
