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.

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

“formation response data comprising data from one or more downhole sensors or surface sensors” and “selecting a representative system model based on the received formation response data and sequence of stimuli” are mental processes. We determine that the record supports that they are. The Background of the ’058 patent supports our finding that these steps are mental processes. In particular, the ’058 patent teaches that it was known that “a technician may review sensor data” and that “a representative system model may be used for determining pump settings based on sensor information; however, the representative system model is typically manually selected by a technician based on observed sensor data.” Id. at 22 (quoting Ex. 1001, 1:9–26); see also Dec. 23–24 (preliminarily finding these claimed patent). Regarding the claimed step of “controlling an electrical fracturing pump based on the representative system model,” Patent Owner does argue, and we agree, that it is not a mental process in that one of ordinary skill in the art would not have performed it in the human mind. PO Resp. 27. We also agree that the Petition does not expressly argue that the step of “generating a sequence of stimuli for application to a well environment” is a mental process. However, the ’058 patent explains that these two steps may be performed via a generic computer. Ex. 1001, 6:6–36, 6:65–7:33, 8:56–9:28. Requiring the use of a computer does not change the focus of the claim away from being directed towards an abstract idea. “[T]he inability for the human mind to perform each claim step does not alone confer patentability.” FairWarning IP, LLC v. Iatric Sys., 839 F.3d 1089, 1098 (Fed. Cir. 2016) (“As we have explained, ‘the fact that the required calculations could be performed more efficiently via a computer does not materially alter the patent eligibility of the claimed subject matter.’” (quoting Bancorp Servs. v. Sun Life Assur. Co., 687 F.3d 1266, 1278 (Fed. Cir. 2012)). See also Miller Mendel, Inc. v. City of Anna, Texas, 107 F.4th 1345, 1353 (Fed. Cir. 2024). (“We are not persuaded that claim 1 cannot be directed to an abstract idea even if certain steps cannot be completed in the mind or by pen and paper. . . . [R]equiring the use of a computer alone does not change the focus of a claim directed towards an abstract idea into one directed towards ‘a specific improvement to computer functionality.’ In re TLI Commc'ns LLC Pat.

Step 2B Under Step 2B, only if a claim (1) recites a judicial exception and (2) does not integrate that exception into a practical application, do we then look to whether the claim: (3) adds a specific limitation beyond the judicial exception that is not “well-understood, routine, [and] conventional” in the field; or (4) simply appends well-understood, routine, conventional activities previously known to the industry, specified at a high level of generality, to the judicial exception. 2019 Revised Guidance, 84 Fed. Reg. at 56. applying the … abstract idea using techniques that are, whether considered individually or as an ordered combination, well-understood, routine, and conventional.’ cxLoyalty Inc. v. Maritz Holdings Inc., 986 F.3d 1367, 1377 (Fed. Cir. 2021).” Pet. 97. The Petition cites the Background of the ’058 patent to support its argument that the specification admits that many of the claimed steps were known. Id. at 91. In the oil and gas industry, electric frac pumps are often controlled in order to achieve certain downhole environment responses. However, typically settings are performed manually based on manually appraised information retrieved from the downhole environment. For example, a technician may review sensor data and, based on experience, adjust various settings such as flow rate, pressure values, chemical compositions, etc., on an electric frac pump. In some cases, a representative system model may be used for determining pump settings based on sensor information; however, the representative system model is typically manually selected by a technician based on observed sensor data. Additionally, the representative system model may be a static construct and may not accurately reflect the well to which it has been deployed. Ex. 1001, 1:9–26 (emphasis added). From the above, it will be understood that much of claim 1 was well-understood, routine, and conventional, whether considered individually or as an ordered combination. The above paragraph makes clear that “controlling an electrical fracturing pump based on the representative system model” was known and conventional. In addition, adjusting settings on an electrical fracturing pump is also how the ’058 patent teaches to generate a sequence of stimuli. Ex. 1001, 2:25–33 (“A given stimulus of the sequence of stimuli can be achieved by adjusting . . . flow rates . . . . In some examples, a sequence can include a various amplitudes (e.g., high, medium, low, etc.).”). Thus, generating a sequence of stimuli is also acknowledged as being known in the Background. See also Dec. 22–23 (preliminarily finding that these limitations were known). Petitioner provides additional argument that other references also show that these limitations were known. See e.g., Pet. 94. However, it is not necessary for us to review these in view of the express acknowledgement of the state of the art in ’058 patent. Based on the record, we determine that claim 1 does not include any specific limitation beyond the judicial exception that is not “well-understood, routine, [and] conventional” in the field.” slip op. at 15
