“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

RulingsFinal written decision- Patent Eligibility (§101) › Alice/Mayo step one — 'directed to'Step1 directed to exceptionUnpatentable
“all directed to “time-based trade analysis” “improperly describes the claims at too high a level of abstraction, as warned against in” Enfish, LLC v. Microsoft Corp., 822 F.3d 1327, 1335, 1337 (Fed. Cir. 2016). PO Resp. 5–6. We disagree. Petitioner’s articulation of the abstract idea to which claim 1 is allegedly directed is appropriately focused and tied to the specific language of the limitations of the claim. Petitioner explains how the recited “price data” and “current system position information” are the key inputs for time-based trade analysis and how calculating a trade recommendation using sub-models based on different times of day constitutes such analysis. See Pet. 31–34. Further, “time-based trade analysis” is not a general field, but rather a particular practice, namely the analysis of potential trades based on time. That type of analysis is reflected expressly in claim 1 via the use of a plurality of sub-models where each is based on “a different time of day.” Petitioner’s analysis is persuasive, as it is consistent with the language of claim 1 and supported by the testimony of Mr. Donefer, which we credit.6 Based on the full record developed during trial, we are persuaded that claim 1 recites time-based trade analysis. Doing so is a fundamental economic practice, which is one of the certain methods of organizing human activity identified in the Guidance, and, thus, an abstract idea.” slip op. at 21

“We disagree. Claim 1 does not recite a distributed system architecture, sub-model calculations executed concurrently in parallel, or real-time operation for a large number of users, all of which Patent Owner relies on to show a patent-eligible application of the alleged abstract idea. See Reply 6, 8; Ex. 1038 ¶¶ 22, 25–26. Claim 1 broadly recites “calculating trade recommendation information from each of a plurality of trading sub-models,” each “based on a different time of day,” and “calculating a trade recommendation . . . based on said trade recommendation information from each of said trading sub-models.” The claim does not specify how, when, or by what component the calculations are performed. Thus, Patent Owner’s contention that steps (d) and (e) do not represent well-understood, routine, and conventional activity is not commensurate with the language of the claim. With respect to what is actually recited in the claim, we are persuaded based on the full trial record that the calculations are the abstract idea itself (i.e., the fundamental economic practice of “time-based trade analysis”), rather than additional elements that could transform the claim into a patent-eligible application of an abstract idea. See supra Section II.F.1.b; BSG Tech LLC v. BuySeasons, Inc., 899 F.3d 1281, 1290 (Fed. Cir. 2018) (“[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.”). Regardless, though, Petitioner also has provided persuasive evidence regarding the conventionality of steps (d) and (e), particularly given the broad manner in which they are recited in the claim. See, e.g., Ex. 1004 ¶¶ 69–84; Ex. 1021, 115 (“It is widely documented that return volatility varies systematically over the trading day and that this pattern is highly correlated with the intraday variation of trading volume and bid-ask spreads.”); Ex. 1019, 13 (“Trading models offer a real-time analysis of foreign exchange movements and generate explicit trading recommendations. These models are based on the continuous collection and treatment of foreign exchange quotes by market makers around the clock at the tick-by-tick frequency level.”); Ex. 1031, 728–732 (describing modeling that accounts for time periods of different levels of activity, such as when particular FX markets are open, and using time intervals of “hours, days, weeks or years”). Petitioner also has provided a detailed explanation citing persuasive evidence that, even if claim 1 did require distributed parallel processing and real-time trading model calculations, both were well-understood, routine, and conventional at the time of the ’534 patent. See Reply 9–11, 15–17; Ex. 1038 ¶¶ 23 (citing, for example, Ex. 1031, 228–232), 29–35 (citing, for example, Ex. 1031, 718). We credit Mr. Donefer’s testimony, which is supported by evidence in the record and unrebutted—Patent Owner did not address the evidence discussed in the Petition and Mr. Donefer’s initial declaration in its Response, did not file a Sur-Reply addressing Mr. Donefer’s reply declaration and cited evidence, and did not provide any contrary evidence in the record.

“testimony of Mr. Donefer, for why a person of ordinary skill in the art would have had reason to combine Pictet’s teachings and arrive at the method of proposed substitute claim 13. Id. at 24–25 (citing Ex. 1031, 716–723; Ex. 1038 ¶¶ 52–58, 75–77). Petitioner argues that a person of ordinary skill in the art “would have recognized that Pictet’s data collection and storage steps (i.e., steps (a)-(c)) provide inputs for the subsequent calculations (i.e., steps (d)-[(e)]),” “would have understood Pictet as teaching that the distributed parallel processing . . . applies to the implementation of the trading models performing those calculations,” and would have had “reason to use at least five of the parameters discussed [in Pictet] when configuring the rules governing the ‘grand’ model.” Id. at 24. Petitioner further contends that numerous types of parameters were routinely used when designing and evaluating trade models, and Pictet’s moving average . . . is no different. Moreover, Pictet describes two categories of threshold values (i.e., trend and overbought/oversold) and expressly teaches using “several threshold values of both types,” which at a minimum suggests four such parameters. The voting scheme is also an integral part of the weighted moving average Pictet describes. A [person of ordinary skill in the art] also had reason to incorporate a time parameter setting the amount of time in the past that is considered, since a [person of ordinary skill in the art] would have understood that price data from the distant past is less 984, 990 (Fed. Cir. 2020) (non-precedential) (recognizing that “the Board need not address issues that are not necessary to the resolution of the proceeding”). relevant to a moving average. Pictet also teaches using stop-loss and stop-profit parameters as part of its model implementation. Id. at 24–25 (citations omitted). We have reviewed Petitioner’s analysis and find it persuasive. Petitioner’s reasoning is consistent with the disclosure of Pictet and supported by the testimony of Mr. Donefer, which we credit. For the reasons stated by Petitioner and Mr. Donefer, we find that a person of ordinary skill in the art would have had reason to combine the cited teachings of Pictet in the manner asserted with a reasonable expectation of success.” slip op. at 53

“3. Patentability Pursuant to 37 C.F.R. § 42.221(d)(2), Petitioner “bears the burden of persuasion to show, by a preponderance of the evidence,” that proposed substitute claim 13 is unpatentable. Petitioner argues that proposed substitute claim 13 fails to recite patent-eligible subject matter under 35 U.S.C. § 101, is indefinite under 35 U.S.C. § 112, second paragraph, and would have been obvious under 35 U.S.C. § 103(a). Opp. 3–25. For the reasons explained below, we determine that Petitioner has met its burden to show, by a preponderance of the evidence, that claim 13 is unpatentable as claiming patent-ineligible subject matter under 35 U.S.C. § 101 and obvious under 35 U.S.C. § 103(a), and need not reach Petitioner’s arguments regarding definiteness under 35 U.S.C. § 112, second paragraph.” slip op. at 39
