“We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

“defined stoichiometry” (Ex. 2037, 527) but the word may also be a “generic term for phases . . . which may have a narrow or extended compositional stability range” (id.). The first glossary meaning is consistent with Patent Owner’s position. The second, broader, glossary meaning is consistent with Petitioner’s position. Some of the extrinsic sources before us support the broad definition, and some support the narrow definition. See PO Sur-Reply 3–4 (arguing that Dr. Miles admitted that various treatises distinguish intermetallic compounds from alloys and solid solutions). Thus, neither Dr. Miles or Dr. Raabe is “wrong scientifically” in how they use the term “intermetallic” in this proceeding. Id. at 2 (noting that Dr. Miles agreed that Dr. Raabe’s construction is not wrong scientifically). As explained below, however, only one of these meanings is appropriate here. To decide which possible meaning applies to the ’227 patent, we focus on the patent claims and specification. Claim 1 indicates that the intermetallic layer has a “mean composition” (emphasis added). Ex. 1001, 15:1–10. This indicates, albeit weakly, that iron composition across the layer may vary rather than having ordered stoichiometry—consistent with Petitioner’s position. The specification also indicates that “intermetallic alloying” is a possibility—again, consistent with Petitioner’s position. Ex. 1001, 2:47–50. Meanwhile, nothing in the ’227 specification explicitly (or implicitly) suggests that “intermetallic layer” must be limited to elements atomically joined with defined stoichiometry in an ordered crystal structure. We also find that Dr. Miles’s testimony regarding the meaning of “intermetallic” is more credible than Dr. Rabbe’s testimony. Dr. Rabbe, in deposition, stated that Figure 2 of the challenged patent “does not show a layer that meets [his] construction of intermetallic.” Ex. 1078, 129:21–24. The ’227 patent, however, states that Figure 2 includes an “Al-rich Intermetallic layer.” Ex. 1001, Fig. 2, 3:60–64 (“FIG 2. Illustrates a coating … which does not correspond to the invention. This succession of layers (interdiffusion layer and intermetallic layer) yields inferior results in resistance spot welding.”). Also, Dr. Raabe previously referred to a layer of Takagi as having “intermetallic phase layering and structure.” Pet. Reply 4 (citing Ex. 1076 ¶ 166; Ex ¶ 1075, 17) (emphasis omitted). Thus, Dr. Raabe’s construction of “intermetallic” for this proceeding does not fully account for the ’227 patent usage of the word “intermetallic” and does not fully account for Dr. Raabe’s prior usage of the word “intermetallic.” Patent Owner argues that Petitioner’s construction “erases the meaningful distinction” between the claimed layers. PO Resp. 11. Patent Owner further argues that Petitioner’s construction renders the word “intermetallic” superfluous because allowing the intermetallic layer to be “merely a multi-element alloy erases the meaningful distinction among these layers.” Id. We disagree. The word intermetallic serves to require that the layer be composed of two or more metals or a metal and a metalloid. The word intermetallic also serves as a label to differentiate each of the four claimed layers. For example, in claim 1, the word “intermetallic” is used much like the words “interdiffusion” and “intermediate” to give each of the four layers (each having differently mean compositions) different labels.” slip op. at 16

“have had reason to combine teachings of Takagi and Cornette with a reasonable expectation of success. Pet. 11–20 (citing, e.g., Ex. 1003 ¶¶ 28– 42; Ex. 1016 ¶ 35; Ex. 1014, 9; Ex. 1025, 5:17–20; Ex. 1026, 7; Ex. 1034 ¶ 13). In particular, Petitioner argues that Takagi discloses a pre-coating thickness of 10–20 µm but does not explicitly disclose a post hot-stamping coating thickness corresponding to the pre-coating thickness. Pet. 11. Cornette teaches that the hot-stamping thickness causes coating expansion from 25 µm to about 40 µm, an increase of 60%. Id. (citations omitted). Petitioner and Dr. Miles reason that, when hot stamping Takagi’s product, the thickness would be 32 µm. Id. (citing Ex. 1003 ¶ 32); see also Pet. Reply 20–21. Thus, Patent Owner argues that Cornette evidences Takagi’s finally coating thickness without requiring modification of Takagi. Petitioner further argues that Takagi and Cornette teach that post hot- stamping thickness could be varied and optimized as a result effective variable. Id. at 12–13; see also Pet. Reply 17–18. Cornette teaches, for example, that “[t]he average [pre-coating] layer thickness showing the best compromise between corrosion protection and weldability is 25 µm” and links this pre-coating thickness to a final thickness of “about 40 µm at the steel surface.” Ex. 1014, 9. Petitioner also argues that it would have been obvious to fill in other details of Takagi including, for example, selecting USIBOR 1500 steel, based on the teachings of Cornette. Pet. 14. Patent Owner argues that there is no reason to combine Takagi with the teachings of Cornette. PO Resp. 26. Patent Owner makes seven related arguments. Patent Owner first argues that the Petitioner’s position is speculative and lacks basis. Id. at 26–27. We disagree. Cornette evidences a final coating thickness for Takagi, and the references also suggest that final coating thickness is result effective. Second, Patent Owner argues that there would have been no incentive to seek a motivation to seek a thicker coating post-hot stamping. Id. at 28– 35. This argument does not undermine Petitioner’s position that Takagi, by itself, would have reached a thicker coating after stamping as evidenced by Cornette. Pet. 11–12. Petitioner takes the position, with evidence, that practice of Takagi alone would reach the recited thickness. No motivation to modify Takagi is required under this position.” slip op. at 25

“We find Patent Owner’s argument to be persuasive. Petitioner does not explain adequately how Bruner discloses the positional requirement of a subscriber access unit being coupled between the satellite dish and the router. Accordingly, Petitioner has not shown sufficiently for purposes of institution that Bruner anticipates independent claim 24. Although, for the obviousness challenge, Petitioner contends that Clark discloses a wireless router (for limitation 24c), Petitioner relies solely on Bruner for the “between” limitation. See Pet. 17 (“Bruner and/or Bruner in view of Clark both disclose each limitation of claim 24c, including a router (e.g., Bruner’s ‘ADS’ and Clark’s ‘wireless router’)”); id. at 18–19 (the discussion of the “between” limitation 24d asserting that “Bruner discloses claim 24d,” with no mention of Clark). Furthermore, Petitioner merely asserts that both Bruner and Clark disclose a router. See id. at 17–18. Petitioner, however, does not indicate clearly which is used in the proposed combination, does not describe the configuration of a proposed combination or a proposed modification of Bruner’s system, and fails to set forth an adequate and persuasive reason with rational underpinning as to why a person of ordinary skill in the art would have modified Bruner’s system to arrive at the positional requirement of the subscription access unit being coupled between the satellite dish and a router. See id. at 13–14 (motivation section for this ground); id. at 18–19 (addressing the “between” limitation 24d).

“CLAIM CONSTRUCTION B. In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

“At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed.

EX1002, ¶68. Such a person of ordinary skill would have at least a general understanding of general construction processes and materials used in the manufacturing process of fabric-based articles. For individuals with a lower educational level, a person could still be of ordinary skill in the art provided that person’s working experience compensates for any such lower educational level, or vice versa. See id. Pet. 23–24. Patent Owner states that, “[f]or purposes of this Preliminary Response, Nike applies Skechers’ definition for a person of ordinary skill in the art.” Prelim. Resp. 14.
