The parties’ proposed levels of ordinary skill are substantially similar. Although we discern no difference in the outcome of this decision from choosing one over the other, we adopt Petitioner’s proposal for this decision. Only Petitioner’s proposed level is supported by testimonial evidence on the preliminary record, and it appears to be consistent with the problems addressed in the ’774 patent. See Ex. 1001, 1:16–52.

“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.

“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard.

“After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims. As we explain in Section III(G), infra, Petitioner’s challenges to the ’227 patent appear strong based on the current record, and Patent Owner’s present arguments to the contrary are weak.

CONCLUSION For the reasons above, we determine that the information presented in the Petition establishes that there is a reasonable likelihood that Petitioner would prevail with respect to challenged claims 1–30 of the ’602 patent. At this juncture in the proceeding, we have not made a final determination with respect to the patentability of the challenged claims, or with respect to claim construction. V. ORDER For the foregoing reasons, it is ORDERED that pursuant to 35 U.S.C. § 314(a), an inter partes review of claims 1–30 of the ’602 patent is hereby instituted with respect to all grounds of unpatentability set forth in the Petition; and” slip op. at 36

“efficiency and integrity of the system are best served by denying or instituting review.” Fintiv at 6. Here, Fintiv factors one and five are neutral, factors two and three favor discretionary denial, factor four strongly weighs against discretionary denial, and favor six weighs against discretionary denial. The integrity of the system will benefit from institution because of the strong merits the Petition presents (factor six), and the ITC Investigation will not resolve these merits (factor four). This outweighs any potential inefficiency as indicated by factors two and three. We further note that any inefficiency in resolving the grounds the Petition presents is mitigated by the stay of the district court action (factor one).

“After considering the record as a whole, we determine that Petitioner has adequately demonstrated that the Office erred in a manner material to the patentability of challenged claims.

“At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments. Patent Owner does not cite to evidence, such as expert testimony, to support its implied argument that Olson’s measured current is “fundamentally different” from the current received by the primary coil. See Prelim. Resp. 31–32. Petitioner’s declarant, Dr. Woods, on the other hand, testifies, inter alia, that “[t]he ‘[c]urrent measured by current measure block 226 is used in the calculation of power, which as depicted in FIG. 14, measures the ‘power in’ provided to transmit block 214/primary coil 54.” Ex. 1003 ¶ 37 (citing Ex. 1004 ¶¶ 74–75, Fig. 14) (first alteration added); see also, e.g., id. ¶ 42 (Dr. Woods testifying that the measured current to the power supply “is the current driving the external antenna 52, via the transmit block 214 and to the primary coil 54.” (citing Ex. 1004 ¶¶ 74–75, 112, Fig. 14)). Paragraph 75 of Olson, cited in support of that testimony, provides: “The power in is gauged by the power generated by charging unit 50 and is determined by multiplying the voltage of the internal voltage of charging unit 50, e.g., the voltage of a battery or batteries internal to charging unit 50, by the current driving external antenna 52.” Ex. 1004 ¶ 75 (emphasis added). We note that external antenna 52 includes primary coil 54. See, e.g., Fig. 14. Dr. Woods’ testimony is, at this stage, unrebutted. Patent Owner also argues that “Petitioner fails to provide any evidence regarding the function of Olson’s microprocessor 212 in relation to measuring input power,” and that, “[w]hile Olson describes a power calculation in paragraph [0075], Olson does not describe this power calculation as performed by microprocessor 212.” Prelim. Resp. 32 (citing Pet. 16; Ex. 1004 ¶ 72) (first alteration added). At this preliminary stage of the proceeding, we do not agree with Patent Owner’s arguments regarding the microprocessor. Although Patent Owner does not bear the burden to show patentability, we observe that Patent Owner does not suggest that there is another component in Olson’s external charging device that might perform the admittedly-disclosed power calculation. See Prelim. Resp. 32–33. Dr. Woods testifies that microprocessor 212 receives the measured current and the input voltage of the charging device, and, from those values, calculates power in. See Ex. 1003 ¶¶ 43–44 (citing, inter alia, Ex. 1004 ¶¶ 71–78, Fig. 14); see also Ex. 1004 ¶ 74, Fig. 14 (Olson stating that “[c]urrent measured by current measure block 226 is used in the calculation of power in along with the voltage of batteries 160,” and Figure 14 depicting the signal from measure block 226 as an input to microprocessor 212).

“b) Reason to Combine & Expectation of Success As explained earlier, Petitioner asserts that it would have been obvious to improve Zhou’s video stabilization techniques by using the techniques in Cai for using future frames to characterize the video as having zero motion or not. Pet. 36. Patent Owner first argues that neither reference “offers any hint or suggestion of combining such reactive systems to create a proactive stabilization solution.” Prelim. Resp. 17; see also id. at 17–19 (similar). Patent Owner has not offered a claim construction, or otherwise explained, how the claims require a “proactive stabilization solution.” Thus, this argument is unpersuasive. Patent Owner next argues that Zhou and Cai are technically incompatible. Id. at 20–23. In particular, Patent Owner argues that Zhou “uses buffering to adjust stabilization strength,” whereas Cai uses buffering “for trajectory adjustment and distinguishing jitter from zero-motion or lowspeed movements.” Id. at 21–22 (emphasis removed). On this record, however, we are not provided with sufficient technical reasoning explaining how using the buffer for one purpose precludes its use for another purpose. Patent Owner cites its declarant, Dr. Foroosh, but his testimony merely repeats Patent Owner’s arguments without any meaningful elucidation. Id. at 22 (citing Ex. 2001 ¶ 70); 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.”); Xerox Corp. v. Bytemark, Inc., IPR2022- 00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential).
