    “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.

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.

    “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.

Id. (citing Ex. 1004 ¶¶ 108–109; Ex. 1010 ¶ 419). Mr. Kasdorf’s declaration testimony is nearly verbatim to the Petition and similarly provides no indication as to what in CryptoKube constitutes a “mining processor” other than his conclusory opinion that one of ordinary skill in the art “would have understood that to mine bitcoin, the mining processors need to be connected to a network interface and adapted to mine transactions associated with the 19 We note that Mr. Kasdorf’s reliance on Kheterpal is limited to Kheterpal’s background discussion regarding the Bitcoin protocol inasmuch as it “defines a system in which the creation and distribution of the bitcoin cryptocurrency is governed by consensus among a peer-to-peer network” and includes “a public ledger in which new transactions are verified and recorded by members of the network via cryptography.” Ex. 1010 ¶ 4.

In determining whether an argument is a proper argument in reply, we look to see if the Reply argument is responsive to an argument from Patent Owner and expands on a position in the Petition. See Rembrandt Diagnostics, LP v. Alere, Inc., 76 F.4th 1376, 1384 (Fed.

We find that Petitioner’s argument in reply is closer to the later situation.

Rather, Petitioner supplements its conclusory assertion that a “mining processor” is necessarily present in CryptoKube’s spondooliestech SP35 servers (Pet. 23, 25 (citing Ex. 1006, 1–4)) with its new assertion that that “a combination of an ASIC chip and a controller would meet the ‘mining processor’ limitation.” Pet.

    “As can be seen from claim 1 above, all of the claimed method steps occur “at the mobile device” and the final step is to enable completion of a cashless transaction. Claim 1 does not recite completing the purchase. The ’833 patent describes that any commercial transaction is completed at the automatic retail machine, not at the mobile device. Ex. 1001, 11:5–9; see also id. at 21:4–11, 22:18–20, 23:53–61, 30:25–27. We, thus, agree with Patent Owner that the claimed method does not require completing or conducting the transaction, but only enabling the completion of the transaction. On this complete record, we are persuaded that the elements italicized above recite the concept of obtaining authorization for a purchase and enabling completion of a cashless transaction, prior to user selection of any items or services. See Pet. 22–23 (arguing that the claimed method “is effectively no different than a person entering a store, the store checking the customer’s available credit (or calling a bank to do so) and when the customer decides on the item, completing the purchase”); Pet. Reply 5–6 (arguing that the claim recites “obtaining payment authorization and performing a financial transaction, the same as a person entering a store, the store checking the customer’s available credit (or calling a bank to do so) and, when the customer decides on the item, allowing the purchase”). In particular, claim 1 recites steps for obtaining authorization prior to user selection of any items or services — steps of identifying the automatic retail machine, obtaining a request from the electronic payment device, sending the request to a server, and obtaining from the server an authorization grant. Claim 1 also recites steps for enabling the completion of a purchase (i.e., cashless transaction) — detecting a trigger condition and sending the authorization grant to the electronic payment device. Our slight revision of the abstract idea from what we previously stated in our Institution Decision does not impact the patentability analysis. Apple, Inc. v.

    “We are not persuaded. Patent Owner’s arguments rest on the alleged novelty of the abstract idea itself, not the “specific limitation beyond the judicial exception,” i.e., the additional elements. “[A] claimed invention’s use of the ineligible concept to which it is directed cannot supply the inventive concept that renders the invention ‘significantly more’ than that ineligible concept.” BSG Tech LLC v. Buyseasons, Inc., 899 F.3d 1281, 1290 (Fed. Cir. 2018). A novel and nonobvious claim directed to a purely abstract idea is, nonetheless, patent ineligible. See Mayo, 566 U.S. at 90. “The ‘novelty’ of any element or steps in a process, or even of the process itself, is of no relevance in determining whether the subject matter of a claim falls within the § 101 categories of possibly patentable subject matter.” Diehr, 450 U.S. at 188–89 (emphasis added). Patent Owner and Dr. Shamos do not identify, and we cannot find, anything in the claim suggesting that the mobile device, server, or automated retail device (i.e., the additional elements) are more than generic components. Indeed, the ’833 patent’s specification demonstrates that these elements were well-understood, routine, and conventional to the industry. Ex. 1001, 2:23–29, 37–42, 3:25–38 (explaining that Offer “teaches permitting the cashless utilization of a vending machines via a communications service, such as a cellular telephone;” Khan teaches an application on a user’s “personal trusted device” used to effectuate cashless purchases; and Carlson teaches “a system and a method for using a portable consumer device such as a mobile phone for payments and the like,” the method including prompting a user to select, from his mobile device, a product for purchase at a vending machine, after/if the user is authorized to make the purchase, and sending an authorization response to the vending machine from a “remote payment server”).” slip op. at 26

Claim Construction The Board interprets claims of unexpired patents using the broadest reasonable construction in light of the specification of the patent in which they appear. 37 C.F.R. § 42.300(b). Under the broadest reasonable construction standard, claim terms are given their ordinary and customary meaning, as would be understood by one of ordinary skill in the art in the context of the entire disclosure.

In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). In the absence of such a definition, limitations are not to be read from the specification into the claims. In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993). Prior to construing the relevant claim limitations, we turn to some initial matters raised by Patent Owner. First, Patent Owner argues that we must construe “the entirety of the challenged claims” (PO Resp. 31), and proposes constructions for some, but not all, limitations of the challenged claims (see id. at 34–36).
