“Although we agree with Petitioner that the plain meaning of limitation 1.2 does not require the recited determination to occur at the first well, it does require the determination to be about the condition(s) of the fluid communicated to the first well by the manifold, regardless of where or how the information is gathered to make that determination. Limitation 1.2 recites plainly that the “determining” step is specifically about whether “the fluid communicated via the manifold has satisfied one or more conditions.” Ex. 1001, 22:38–39 (emphasis added). Considering the antecedents for “the fluid” and “the manifold”––i.e., “communicating fluid to a first well via a manifold” (id. at 22:35, limitation 1.1)––limitation 1.2 expressly identifies the fluid which “the manifold” has “communicated” to the first well to be exactly the fluid used for “determining” whether “one or more conditions” are “satisfied” to trigger the recited responses. Id. This is because “the fluid” refers to a fluid passing to a first well by way of a manifold and the past tense of “communicated via the manifold” indicates, more specifically, that it is the fluid passed by the manifold which must satisfy a condition(s). The Specification of ’770 patent illustrates this by checking the “frac rate” of the fluid discharged by a manifold to a first well to make the determination about whether to permit a regular swap or a continuous pumping swap (“CP swap”). Ex. 1001, 13:30–54, Fig. 12. Therefore, contrary to Petitioner’s representation that limitation 1.2 does not “requir[e] the fluid used for ‘determining’ to have been communicated to the first well” (Pet. Reply 3), the plain meaning of limitation 1.2 does require the fluid used” slip op. at 12

“anticipated by, or would have been obvious over, Krupa necessarily requires Krupa to be first qualified as prior art. See Tech. Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1327 (Fed. Cir. 2008) (party’s burden to prove anticipation of a patent includes initial burden of going forward with evidence that there is anticipating prior art). Under 35 U.S.C. § 102(a)(2)— the subsection under which Petitioner contends Krupa qualifies as prior art—when the reference patent document’s actual filing date is before the challenged patent’s filing date, a petitioner need only refer to the filing dates appearing on the challenged patent and reference patent document to make prima facie showing that the reference is prior art. 35 U.S.C. § 102(d)(1) (“For purposes of determining whether a patent or application for patent is prior art to a claimed invention under subsection (a)(2), such patent or application shall be considered to have been effectively filed, with respect to any subject matter described in the patent or application—(1) if paragraph (2) does not apply, as of the actual filing date of the patent or the application for patent.”).” slip op. at 16

“We determine that the Petition did not adequately present Petitioner’s contention that Tolman discloses or suggests a “master valve” that a skilled artisan would understand to be the claimed “first valve,” which is first introduced in the Reply. The issue is whether Petitioner’s identification of Tolman’s “tree valve” for the claimed first valve was particular enough to allow Petitioner to rely specifically on the “master valve” in the well tree to show Tolman discloses the first valve. We find that it is not. It is undisputed that a well tree include several different valves: (1) valves for communicating fluid to a well (e.g., for treatment or stimulation); (2) valves for communicating fluid from a well (e.g., for flowback); and (3) valves for communicating fluid both to and from a well (e.g., master valve). See Reply 19–20; Ex. 1002 ¶¶ 542–545; Ex. 1044 ¶¶ 33–34, 38–42; Tr. 33:12–18, 34:3–12, 36:8–37:18, 39:4–17; Ex. 2013, 85:4–86:19, 87:1–12, 89:2–11. And the opening/closing of these different valves are controlled independently of the other valves based on different parameters. Id. identifying a tree valve, generally, does not provide the particularity necessary to provide notice that the master valve is the particular valve being relied upon. Further compounding this problem is the fact that the Petition repeatedly refers to a plurality of valves, rather than a singular “master valve.” The variability of possible valves suggested by simply referring to a tree valve fails to provide a level of particularity that clearly identifies which specific structure is being relied upon to perform which part of the recited procedure. Ultimately, we agree with Patent Owner that because the Petition does not specifically identify the master valve in the Petition, which the Petitioner’s Reply suggest was the intention all along, Patent Owner was put at a disadvantage because its ability to fully develop a response was impeded. Therefore, Petitioner’s reliance particularly on the “master valve” of the well tree, and the newly introduced evidence associated therewith, was improper and may not be considered. Nevertheless, as discussed below, even if Petitioner were allowed to rely on the master valve, we still find the Tolman Grounds to be deficient.” slip op. at 56

“However, Carr does not disclose or suggest: relying on the condition(s) of the fluid communicated by first isolated manifold path 122 to first well 140 to be the determinative factor for causing first and second valves 470 and 472 to perform a sequenced response that includes–– (1) opening second valve 472, (2) communicating fluid to second well 142 through second valve 472, and (3) after opening second valve 472, closing first valve 150 from communicating fluid to first well 140. At the time of the invention, when a first well is being operated individually using high pressure pumping, we find that skilled artisans would have considered concurrent operation of the second well’s valves to be hazardous and activities that can not occur. See Ex. 1031, 4 (“specifically identified activities that were restricted from occurring at the same time (i.e., CAN NOT OCCUR activities). As an example, if the operations on a well involved high pressure pumping . . . then manipulating manifold well valves and wellhead trees valves on another well were not allowed to be performed concurrently”); Ex. 2012 ¶ 148. would have had a reasonable expectation of being able to successfully avoid the unacceptable hazards known to be associated with opening second valve 472 and communicating fluid to second well 142, while individually operating on first well 140 using high pressure pumping.10 Furthermore, Petitioner provides no persuasive evidence that a skilled artisan would have known that those unacceptable hazards could be avoided (or acceptably minimized) by using a condition(s) of the fluid communicated by first isolated manifold path 122 to first well 140 as a trigger for opening second valve 472 and communicating fluid to second well 142, while first well 140 is being individually operated.” slip op. at 34

RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for patent owner
“In our Initial and Rehearing Decisions, we noted that Patent Owner did not contest Petitioner’s proffered level of ordinary skill in the art at that stage of the proceeding and we found “Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the ’308 patent and the prior art of record.” Initial Dec. 13 (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978)); Rehearing Dec. 16 (same). Therefore, we adopted Petitioner’s unopposed position as to the level of ordinary skill in the art. Initial Dec. 13; Rehearing Dec. 16. In its Patent Owner Response, Patent Owner states that “[f]or purposes of this proceeding, Patent Owner does not dispute Petitioner’s offered level of ordinary skill in the art.” PO Resp. 7. Accordingly, we maintain our preliminary finding by adopting Petitioner’s proposed level of ordinary skill in the art, as set forth above.” slip op. at 13

“received message 7102 and the header of the response message 7202 are not the same. PO Resp. 25 (citations omitted); Pet. Reply 14. In the Petition, Petitioner argued that “header information” was the same in each message (received and response). Pet. 32 (citations omitted), 36–37. Petitioner relies on Tables 58 and 63, which show “Header.” Id. at 32–33, 37. Petitioner also relies on paragraphs 102 and 118 of Mr. Andrews’s Declaration. Neither the Petition nor Mr. Andrews’s Declaration, however, provide any sufficient basis to find that even a portion of the header or header information is copied from the received message to the response message. Mr. Andrews states his opinion as though it were fact without providing the underlying factual support for his opinion. See Ex. 1003 ¶¶ 102, 118; see 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). In cross-examination, Mr. Andrews provided additional information explaining which portion of the headers he believes are the same, but he still does not provide any explanation as to why he believes the information is copied. See, e.g., Ex. 2007 at 111:3–25. The same is true of Petitioner’s Reply, which reiterates Mr. Andrews’s deposition testimony, but still fails to provide any reason as to why Coffee’s charts or Mr. Andrews’ testimony necessarily means that Coffee copies a portion of the header from the received message to the response message. See Continental Can Co. U.S.A., Inc. v. Monsanto Co., 948 F.2d 1264, 1269 (Fed. Cir. 1991) (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”). And, despite Petitioner’s identification of a “Header” listed in Tables 58 and 63, Coffee does not expressly describe the header or part of the header as being copied from the received message to the response message. The Petition and Mr. Andrews also state that “if Coffee did not employ such copying, the response message would not automatically include information extracted from the received message.” Pet. 38 (citing Ex. 1003 ¶ 118). But, Coffee does not expressly describe the header as being “extracted from the received message” or describe automatically including the header in a response message to make the leap argued by Petitioner and Mr. Andrews. Accordingly, on the full record before us, we find that Petitioner has not established that Coffee explicitly or inherently discloses copying the header or header information and we do not credit Mr. Andrews’ testimony, discussed above, because he fails to provide the underlying factual basis for the opinions offered.” slip op. at 43

“proceeding and on the full record before us, we do not find that Coffee’s silence is sufficient to support Petitioner’s argument. See Campbell Soup Co. v. Gamon Plus, Inc., 787 Fed. Appx. 731, 739 (Fed. Cir. 2019) (“We do not find any error in the Board changing its understanding of the teachings of [a prior art reference] from the institution decision to the final written decision. ‘The Board is not bound by any findings made in its Institution Decision. At that point, the Board is considering the matter preliminarily without the benefit of a full record. The Board is free to change its view of the merits after further development of the record, and should do so if convinced that its inclinations were wrong.’” (quoting Trivascular, Inc. v. Samuels, 812 F.3d 1056, 1068 (Fed. Cir. 2016))). Coffee does not explain the process by which the IOD of the received message is included in the response message; rather, Coffee just states that the response message “contains the IOD of the message being answered.” See, e.g., Ex. 1005, 56:63–67 (see full text quoted above). In particular, although Coffee attributes certain actions to the operator, the lack of attribution to the operator does not necessitate that the only viable possibility remaining is that Coffee copies the IOD from the received message to the response message. Even if it may be said that Coffee probably (or possibly) copies the IOD, that probability is not sufficient to find that Coffee necessarily copies the IOD. See Continental Can, 948 F.2d at 1269 (“Inherency . . . may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”).7 Additionally, on the full record before us, we determine that Mr. Andrews’s testimony, as with his testimony as to copying of the header and selected response, fails to provide any factual or underlying support for his opinions expressed therein. See Ex. 1003 ¶¶ 100–102. In particular, the leap occurs in paragraph 102, where Mr. Andrews takes the fact that some information (at least the IOD) from the received formatted message is included with the response message to opine that this means the information is “copied over.” Id. ¶ 102. But, again, Coffee is silent. And because Mr. Andrews did not provide any underlying factual basis for his opinion, we do not credit his testimony as to copying the IOD. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”).” slip op. at 48

“generally, including the alleged benefits of such and reasons why one of ordinary skill in the art would have been prompted to include field-mapping information in Coffee’s MDT. See id. at 62–70. None of Petitioner’s discussion, however, explains how the combination of Coffee and Heijden remedies the deficiencies that we identified regarding Petitioner’s challenge based on Coffee. In particular, Petitioner does not assert or explain how the teachings of Heijden would be applied to Coffee such that Coffee would then copy or fill in the specific information from Coffee’s received message to Coffee’s response message, particularly as pertains to the header, Response, and IOD fields (which Petitioner relied on in the first ground), or any other information field from Coffee. The same is true of Mr. Andrews’s testimony. See Ex. 1003 ¶¶ 214–231. Additionally, it appears that Petitioner’s analysis of the combination of Heijden and Coffee maintains the position that Coffee copies information fields. See Pet. 70 (“Given that Coffee’s system already implements field mapping to copy information fields . . . .”). And, Mr. Andrews’s testimony similarly maintains that Coffee copies information fields. See Ex. 1003 ¶ 229 (“Coffee also discloses (at least inherently) field mapping by describing that data is copied from fields in request messages into corresponding fields in response message.”). But, as we explain in detail in the context of Petitioner’s challenge based on Coffee, Petitioner has not shown sufficiently that Coffee copies or fills in information from a received message to a response message. Thus, we do not find and Petitioner does not allege that Ground “1B” fills the gaps identified in Petitioner’s Ground “1A.”10 Accordingly, we determine that Petitioner has not established, by a preponderance of the evidence, that the combination of Coffee and Heijden would have rendered the subject matter of claims 1–4, 7–9, and 12 unpatentable.” slip op. at 60
