      “The parties agree that experience could substitute for a degree, and vice versa. Pet. 3; PO Resp. 10. The parties’ proposed levels of ordinary skill are substantially similar. For this decision, as in the Institution Decision, we adopt Petitioner’s proposed level, which is supported by credible testimonial evidence and is consistent with the problems addressed in the ’774 patent.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

      “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

      “We disagree that Petitioner’s arguments are based on impermissible hindsight, because they are based on the disclosures in Douglas and Mark, and Petitioner has articulated a persuasive reason to combine those references without referring to the ’774 patent itself, as we discuss below. 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”).” slip op. at 29

    • BurdenFwd all claims patentableNot shown unpatentable

      “4. Conclusion for the Prior Art Analysis In sum, we find that Zhou does not disclose the low-light high-pass parameter or the stickiness parameter. Petitioner’s grounds for both independent claims 1 and 16 rely on Zhou for teaching a low-light high-pass parameter or a stickiness parameter. Pet. 23–28, 64. Because we find Zhou does not teach these limitations, all of Petitioner’s grounds fall for this reason. III. CONCLUSION For the reasons given above, we determine that Petitioner has not established by a preponderance of the evidence that any claim of the ’840 patent would have been obvious in view of the prior art cited.” slip op. at 18

    • Expert testimonyPatent owner expert creditedPetitioner expert discountedDecided for patent owner

      “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

Thus, the control component requires a microprocessor and memory with algorithmic structure including a timing algorithm or similar coding for creating a control output signal that flips to control the direction of current flow through a coil (e.g., coil 514, Fig. 5, coil 626, Fig. 6), where the coil is structure that corresponds to the recited “driving component,” as noted above.10 We adopt the District Court’s conclusion in the Apple litigation that the “control component” structure itself does not require an H-bridge switch, but only requires that the processor generates the “d” inputs configured to operate a switch or other circuit; and further that the structure does not require does not require computing initial default values as specified in step 702 of Figure 7A (i.e., values not specified by a user).

The claims only require the control component to control the power supply to cause oscillation at a specified frequency and amplitude, but do not require the frequency value to be generated before the amplitude value, or vice versa.” slip op. at 17

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.

      “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 are persuaded by Patent Owner that the term “automatically” in “to automatically disengage the first and second catch structures” means that it is not just the force applied by the user that disengages the first and second catch structures, but also the bias of the mouthpiece that helps to disengage the first and second catch structures. In the first instance, we agree with Patent Owner that the claim itself recites that, upon actuation, the mouthpiece assembly is “release[d]” to “move via its bias from the stowed configuration to the dispensing configuration.” See Ex. 1001, 21:59–64. This meaning is supported by the Specification which states: “In some examples, the mouthpiece assembly is biased toward the dispensing configuration and thus moves automatically under its bias upon release by the user-release mechanism.” Ex. 1001, 1:64–67. We further agree with Patent Owner that the plain and ordinary meaning of “automatic” is that the user operation alone is not responsible for the action. For example, in one dictionary cited by Petitioner, “automatic” is defined as “2: having a self-acting or self-regulating mechanism.” See Ex. 2007, 1.11 The district court construction is consistent therewith. The district court identified two functions, the first of which is the same as that of the ’028 patent, i.e., “Automatically disengaging the first and second catch structures upon actuation of the user release mechanism and thereby releasing the mouthpiece assembly to move via its bias from the stowed configuration to the dispensing configuration.” See Section II.C.1, supra. In discussing that function, the district court states: “While a user may impart force upon user engagement portion 260 to release the mouthpiece, the bias of the mouthpiece towards the dispensing configuration causes the mouthpiece to move automatically, satisfying the requirements of Claim 1.” Ex. 2002, 16.

      “Institution of an inter partes review is authorized by statute when “the information presented in the petition filed under [35 U.S.C. §] 311 and any response filed under [35 U.S.C. §] 313 shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a) (2018). For the reasons set forth below, we determine that Petitioner has demonstrated that there is a reasonable likelihood that at least one of claims 1–18 of the ’250 patent is unpatentable, and we institute an inter partes review of claims 1–18 based on the grounds set forth in the Petition.” slip op. at 2

      “Petitioner asserts that a person of ordinary skill in the art (“POSITA”) would have had an undergraduate degree in mechanical engineering or equivalent coursework, and a year or more of experience in designing, prototyping, and/or manufacturing fluid containers or similar products. Pet. 15 (citing Ex. 1002 ¶ 25). Petitioner asserts that more work experience may substitute for a lower level of education, and vice versa. Id. Patent Owner admittedly sets forth “a similar, though slightly different, level of ordinary skill”: a bachelor’s degree in mechanical experience with liquid-containing devices, with more work experience substituting for less education and vice versa. Prelim. Resp. 28 (citing Ex. 2001 ¶ 50). Patent Owner discerns no material difference between the definitions provided by the parties for purposes of the Board’s decision on whether to institute this proceeding. Id. For purposes of this decision, we adopt Petitioner’s proposed level of skill as being consistent with the prior art, although our conclusion on whether to institute would be unchanged under either definition.” slip op. at 9

      “For purposes of this decision on institution, we adopt the proffered dictionary definition of “mouthpiece” as “a part (as of an instrument) that goes in the mouth or to which the mouth is applied” (see Ex. 2005), and we construe this as an intended use of this component of the apparatus, because this definition is consistent with the plain and ordinary meaning of the term which is a compound of “mouth” and “piece” and also because this definition is consistent with the Specification. For example, the Specification describes the use of the mouthpiece as follows: “In use, the mouthpiece is adapted to be configured to the dispensing configuration by a user placing the mouthpiece in the user’s mouth and biting upon or otherwise compressing the appropriate portions of sidewalls 92 of the mouthpiece.” Ex. 1001, 8:45–49. We note that, although the Specification refers to bite-actuation of the mouthpiece, for example in the field of the disclosure and certain embodiments (e.g., Ex. 1001, 1:25–27), the independent claims do not require bite-actuation. The Specification identifies the mouthpiece as item 72 (which is depicted, for example, in Figure 25, reproduced supra). Ex. 1001, 3:7‒8. 7 Exhibit 2005 appears to be from an online Merriam-Webster dictionary accessed March 13, 2025. Ex. 2005, 4. At this time, there is no argument in the preliminary record that this definition would have been different before the critical date of the patent.” slip op. at 12

      “Patent Owner argues that a POSITA would have “a bachelor’s degree in mechanical engineering or the equivalent coursework and approximately one year of experience with liquid-containing devices, with more work experience substituting for less education and vice versa.” Prelim. Resp. 23 (citing Ex. 2001 ¶¶ 56–65). Patent Owner also states that it “discerns no material difference between the definitions provided by the parties for purposes the Board’s decision on whether to institute this proceeding.” Id. We agree that there appears to be no material difference in the parties’ definitions of the level of ordinary skill in the art. For the purposes of this Decision, we apply Petitioner’s definition of the level of ordinary skill in the art. We determine that this definition is consistent with the prior art of record and the skill reflected in the Specification of the ’028 patent, based on our review of the limited record. Moreover, the prior art itself may be sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for petitioner

      “as a means-plus-function limitation under 35 U.S.C. § 112, sixth paragraph, because “mechanism” is a nonce word for performing the claimed function without reciting structure for performing that function, and a POSITA would not have understood the term to have “a sufficiently definite meaning as the name for a structure that performs the claimed function.” Pet. 16–17 (citing Ex. 1003 ¶ 39). For claim 1, Petitioner identifies two distinct structures described in the ’028 patent that correspond to the claimed “user release mechanism” for performing the claimed functions. Id. at 34. Specifically, Petitioner asserts that the ’028 patent describes a first embodiment in which the corresponding structure includes sliding member 238, and its component parts. Id. at 34– 35 (citing Ex. 1001, 12:50–13:25, 13:29–33). In the second embodiment, the corresponding structure includes user engagement portion 260 on rigid collar 170. Id. at 35–36 (citing Ex. 1001, 13:40–54). Petitioner does not separately address the structure corresponding to the “user release mechanism” as recited in claim 21. Id. at 53‒54 (relying on the same arguments presented for unpatentability of claim 1). court issued a claim construction order in the parallel litigation construing the term “user release mechanism” as a means-plus-function limitation under § 112, sixth paragraph. Prelim. Resp. 23 (citing Ex. 2002, 12–15). The district court ruled that the corresponding structure for claim 1 includes “[s]liding member 238, including its component parts,” or “[u]ser engagement portion 260.” Ex. 2002, 15. For claim 21, the district court ruled that the corresponding structure includes “[s]liding member 238, including its component parts” or “[u]ser engagement pad 240, planar portion 242, tabs 244, collar engagement portion 254, depression 256.” Id. at 17. Patent Owner indicates that, “[f]or purposes of this proceeding only,” it does not dispute that the claimed user release mechanisms are means-plusfunction limitations, and it does not dispute the corresponding structure identified by Petitioner, even though the district court did not specifically identify engagement portion 260 as corresponding structure for claim 21. Prelim. Resp. 25 (citing Ex. 2002, 15–19). Although Patent Owner does not dispute Petitioner’s proposed interpretation of the “user release mechanism,” because claim interpretation is a matter of law and the dispositive issue in this Decision turns on the interpretation of this claim limitation, we address it in this Decision. We agree with the parties that the “user release mechanism” elements recited in claims 1 and 21 are means-plus-function limitations governed by § 112, sixth paragraph. See 35 U.S.C. § 112 ¶ 6 (“An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.”). “means,” it uses the nonce word “mechanism” without reciting structure for performing the functions recited in the claims. See Williamson v. CitrixOnline, LLC, 792 F.3d 1339, 1350 (Fed. Cir. 2015) (“Generic terms such as ‘mechanism,’ ‘element,’ ‘device,’ and other nonce words that reflect nothing more than verbal constructs may be used in a claim in a manner that is tantamount to using the word “means” because they ‘typically do not connote sufficiently definite structure’ and therefore may invoke § 112, para. 6.”).” slip op. at 13

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “[U]nder § 112, ¶ 6 equivalence, functional identity is required” and “[s]tructural equivalence under § 112, ¶ 6 is met only if the differences are insubstantial, that is, if the assertedly equivalent structure performs the claimed function in substantially the same way to achieve substantially the same result as the corresponding structure described in the specification.” (citing Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308 (Fed. Cir. 1998)). Here, Petitioner states that Kiyota’s lock release buttons 40 “perform the claimed function in the same way to achieve the same result” as the ’028 patent’s sliding member 238, and its component parts (Pet. 37) without providing sufficient supporting explanation or evidence. Petitioner explains only that the two structures operate in “substantially the same way” by a user pressing an element that that slides towards the mouthpiece assembly to disengage the catch structures. Id. at 37–38 (citing Ex. 1003 ¶ 89). The Petition does not discuss any of the differences between Kiyota’s structure and the ’028 patent’s structure or provide an explanation of why these differences are insubstantial. Indeed, as Patent Owner persuasively explains, there are notable differences in the “way” the two structures perform the claimed function and the “result” they achieve. See Prelim. Resp. 39–40 (discussing the ’028 patent’s one-finger operation and indirect catch disengagement, versus Kiyota’s two-finger operation and direct catch disengagement). Moreover, the analysis in Dr. Vallee’s declaration substantially parallels the discussion in the Petition and does not provide any additional explanation or evidence to show that the differences between the “way” the two structures operate or the “result” they achieve are insubstantial. Compare Ex. 1003 ¶¶ 85–91, with Pet. 34–38. For these reasons, Petitioner fails to show sufficiently that Kiyota discloses an equivalent structure to the structure described in the ’028 patent corresponding to the “user release mechanism” recited in claim 1. Accordingly, Petitioner has not met its burden to show a reasonable likelihood that claim 1 is unpatentable as obvious over Kiyota. slip op. at 23

      “The ’494 patent is directed to locating a wireless mobile device in a geographic region. Ex. 1001, 1:20–27; PO Resp. 45.

    • BurdenDecided for petitioner

      “Patent Owner, however, has not identified any language in the Petition that explicitly incorporates by reference Dr. Sundaresan’s testimony. See generally PO Resp.; PO Sur-Reply. Nevertheless, to the extent that the Petition purportedly incorporates by reference Dr. Sundaresan’s testimony, we do not find such incorporation sufficiently extensive to merit disregarding the testimony. Typically, an incorporation by reference is deemed improper in instances in which large portions of a declaration are incorporated—particularly where the incorporation serves to circumvent a word-count limit. See, e.g., Cisco Systems, Inc. v. C-Cation Techs., LLC, IPR2014-00454, Paper 12 at 10 (PTAB Aug. 29, 2014) (informative). In this case, however, Dr. Sundaresan’s testimony describing the level of ordinary skill in the art is short. Ex. 1003 ¶ 8. The amount of testimony is not extensive and, thus, its purported incorporation into the Petition presents little or no imposition on Patent Owner or the Board.” slip op. at 12

      “In reply, Petitioner argues that “under any reasonable read of the Sundaresan Declaration, Dr. Sundaresan implied agreement with the POSITA definition based on its inclusion in a signed declaration.” Pet. Reply 15. We agree with Petitioner. Although Dr. Sundaresan does not state explicitly that the proposed definition of the ordinary skill in the art is his opinion, we are persuaded that the manner in which the definition is set forth in his declaration indicates that he agrees with the definition. Patent Owner attempts to make much of Dr. Sundaresan’s statement that he had been informed of the qualifications of a person of ordinary skill in the art. See PO Resp. 41–43. Dr. Sundaresan’s testimony, however, set forth this understanding of the requisite level of skill in the art (Ex. 1003 9 Dr. Sundaresan has a doctoral degree in electrical and computer engineering and has extensive experience in wireless communications. Ex. 1003 ¶¶ 75–78. Dr. Sundaresan also has experience with navigation and geolocation systems such as development of wireless tracking systems, as evidenced by his experience in companies such as NavigateIO Inc. Id. at ¶¶ 77–78. Patent Owner does not argue that Dr. Sundaresan fails to meet requirements for the level of qualifications of one of ordinary skill in the art under its proposed qualifications, which we adopt here. See generally PO Resp.; PO Sur-reply. Based on a review of his qualifications, we determine that Dr. Sundaresan qualifies as a person of ordinary skill at the time of the invention. ¶ 8). In his supplemental declaration, Dr. Sundaresan testifies: I agreed with this POSITA definition when preparing the Declaration, and I continue to hold the opinion that the POSITA definition is both correct and appropriate based on the disclosures of the ’358 patent and the prior art analyzed in the Declaration. Ex. 1055 ¶ 17. Dr. Sundaresan further testifies that “[i]f I did not agree with the POSITA definition, then it would not have been included [] in paragraph 8 of the Declaration.” Id. ¶ 18. Dr. Sundaresan’s inclusion of the definition of the level of ordinary skill in his original declaration indicates that he agrees with the definition, as confirmed by his cited subsequent testimony. We note that, even with Patent Owner’s arguments, the record is clear that Patent Owner was on notice of Petitioner’s proposed definition of the level of ordinary skill at the time of the Petition. Pet. 6; cf. Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1006 (Fed.

      “parties, we do not find the merits to be particularly strong on the current record. For example, limitation [1-4] recites, in part, “a locking nut having . . . an external thread on an outside surface of the locking nut.” Ex. 1001, 9:46–47. In alleging obviousness based in part on Orphanos, Petitioner equates the claimed “locking nut” to Orphanos’s collet 230 in a first embodiment of Orphanos, or Orphanos’s collet portion 1052 in a second embodiment of Orphanos. Pet. 37–38. Petitioner acknowledges that the collet and collet portion do not have external threads, but rather are designed to have a snap-fit engagement with the inner sidewall of the baseplate’s central throughbore. Id. at 38. Petitioner argues that modifying the collet and collet portion to have external threads would have been obvious to the skilled artisan in view of Orphanos’s teachings and the knowledge of a person having ordinary skill in the art. Pet. 38–42 (arguing, inter alia, that it would have been “a substitution of a known part for a known problem” and “obvious as a matter of design choice”). Petitioner does not allege that replacing the snap-fit coupling with external threads would either: (1) result in any advantages; or (2) preserve any of Orphanos’s stated benefits of its snap-fit arrangement. See Pet. 34–37. That Petitioner describes no advantages to making its proposed modification potentially undermines Petitioner’s case that the skilled artisan would have done so. Cf. Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit . . . should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.”).” slip op. at 16

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITANot reached

      “Petitioner’s arguments regarding the central post and locking nut include an implicit claim construction argument that these components need not be separate structures. Pet. 74, 76–81. Patent Owner, on the other hand, would have us interpret the claim to require that they be separate structures. Patent Owner raises credible evidence to support its theory. Specifically, Patent Owner directs us to the language of claim 1, which separately recites “a central screw” and “a locking nut.” Prelim. Resp. 51; see Ex. 1001, 9:44–53. Patent Owner further contends, in view of the claim language, that the claimed central post and locking nut are separate and distinct components. According to Patent Owner, however, Lefebvre’s main head and anchor rod portions are parts of a single monolithic anchoring screw. Prelim. Resp. 53–58. Where a claim lists elements separately, there is a rebuttable presumption that these elements have separate and distinct physical structures. See Google LLC v. EcoFactor, Inc., 92 F.4th 1049, 1058 (Fed. Cir. 2024) (citing Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1231–1232 (Fed. Cir. 2011)). The presumption may be rebutted by the intrinsic record. Id. At this stage, however, Petitioner does not address that claim 1 appears to separately recite a central post and a locking nut, and does not direct us to any portion of the intrinsic record that might rebut the presumption that these elements are, therefore, separate and distinct structures. See Pet. 73–77. Petitioner also argues that the claim terms “baseplate central channel” and “central channel . . . configured to interface with the baseplate” are indefinite. Pet. 95–102. Patent Owner argues that the plain and ordinary meaning of the terms is clear and that Petitioner “had no problem” arguing how the asserted art purportedly rendered the claims obvious. Prelim.
