  • 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

    “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

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

Moreover, the cited extrinsic evidence––testimony by Patent Owner’s expert Dr. Lomp–– does not support Patent Owner’s proposed construction because it is internally inconsistent and also undermined by Dr. Lomp’s inconsistent deposition testimony. See Ex. 1036, 11:6–17, 12:9–12; Ex. 2010 ¶¶ 40, 48. Similarly, the extrinsic evidence cited by Petitioner (e.g., Exs. 1037, 1038, 2009) undermines Patent Owner’s position emphasizing the intended recipient devices of SIB1. In summary, we decline to adopt Patent Owner’s proposed claim construction because it is unsupported by the claim language, the ’670 Patent Specification, and the cited extrinsic evidence. with the ordinary and customary meaning which does not include limiting SIB1 to an ordinary legacy SIB and excluding MTC specific SIBs or SIBs intended for MTC devices.

See Dynamic Drinkware, 800 F.3d at 1379–1380.

Anascape, Ltd. v. Nintendo of Am. Inc., 601 F.3d 1333, 1337 (Fed. Cir. 2010). To satisfy the written description requirement, “a prior application itself must describe an invention, and do so in sufficient detail that one skilled in the art can clearly conclude that the inventor invented the claimed invention as of the filing date sought.” Lockwood v.

Petitioner implicitly acknowledges that Wallen does not expressly disclose a physical broadcast channel (PBCH), but relies on Berggren for confirming that the LTE standard specifies that a PBCH carries the MIB. See Pet. 42–43 (citing Ex. 1003 ¶ 74; Ex. 1007 ¶¶ 73–75). According to Petitioner, “a person of ordinary skill in the art would have been motivated to transmit Wallen’s MIB using a PBCH as taught by Berggren.” Pet. 43 (citing Pet. 33–38). In particular, Petitioner asserts that a person of ordinary skill in the art “would have been motivated for Wallen’s LTE system to utilize the LTE standard implementation details taught by Berggren,” and “it would have been predictable and beneficial for Wallen’s user equipment to receive the MIB in the [PBCH], as was standard in LTE.” Pet. 34 (citing Ex. 1003 ¶ 58), 37 (citing Ex. 1003 ¶ 63). According to Petitioner, “the combination is nothing more than ‘the predictable use of prior art elements according to their established functions.’” Pet. 38 (citing KSR, 550 U.S. at 417). Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Wallen’s broadcast MIB with Berggren’s teachings of using a PBCH for transmitting broadcast MIBs.

    “Petitioner thus proposes a Master’s degree with two years of experience, while Patent Owner proposes a Bachelor’s degree with five years of experience. At the institution stage, we did not see a material difference in the proposals given that both parties also indicate that more education could substitute for less experience and vice versa, and thus adopted Patent Owner’s proposal. Inst. Dec. 11. We requested that the parties address during trial if either believed that the choice of one proposal over the other would make a difference in the patentability analysis. Id.

Accordingly, because nothing in the record persuades us that our preliminary finding in the Institution Decision was incorrect, and because neither party has challenged our finding, we maintain our adoption of Patent Owner’s proposed level of ordinary skill in the art.” slip op. at 10

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

    “Here, as in the Director’s example, Petitioner advanced a narrower construction of the dynamic limitations before the district court, which the district court declined to adopt. Pet. 10; Ex. 2015; Ex. 2025, 31–47. Instead, the district court adopted a “plain-and-ordinary meaning” construction, which Patent Owner proposed. PO Resp. 36–38; PO Sur-reply 10 n.2; Ex. 2015; Ex. 2025, 31–47. In the Petition, Petitioner proposed applying the plain and ordinary meaning construction that had already been preliminarily adopted by the district court. Compare Pet. (filed May 1, 2024) with Ex. 2015 (preliminarily adopting plain and ordinary meaning construction on March 25, 2024). Applying Revvo, we find that Petitioner had a sufficient reason for advancing the broader, court-adopted construction in this IPR. Thus, we give the dynamic limitation its plain-and-ordinary meaning, which is “adjusting during operation based—at least in part—on information gained during operation.”” slip op. at 14

    “Variable Bandpass Filter Block does not teach the recited “component” or “impedance” that is dynamically adjusted, and instead focus on why the low-pass and high-pass filter circuits do not teach the limitation, which is not Petitioner’s position. As stated above, we agree with Patent Owner’s plain reading of the claim language – i.e., that it “requires adjusting a variable impedance of a circuit or component thereof, while it is in the signal path.” See PO Resp. 49. However, Patent Owner’s reading of the claim does not persuasively address why the Variable Bandpass Filter Block does not teach the recited “circuit” or “component.” We have reviewed Dr. Larson’s cited testimony and disagree with Patent Owner that he provided “a well-supported opinion . . . as to why a [person of ordinary skill in the art] would not understand the entire bandpass box to be “a component,” “a circuit,” or “an impedance” in the claims.” Sur-reply 4 (citing Ex. 2020 ¶¶ 46–48, 71, 74–83). Dr. Larson testifies that the ’330 patent “teach[es] these adjustments [that dynamically change operating parameters] as changes effected in a single circuit block.” Ex. 2020 ¶ 46 (citing, e.g., Ex. 1001, Figs. 8A, 9A, 8:20–25, 8:36–39, 9:36–59, 10:1–18 (emphasis added)). Dr. Larson does not provide further explanation as to what he means by a “single circuit block,” but relies on Figures 8A and 9A, which show a “function block,” and other disclosures referring to a “function block.” Id. There is no dispute that the recited “circuit” or “component” in the receiver signal path is referring to these “function blocks.” See Tr. 22:20–23:4. The ’330 patent states that Figure 8A, which includes function block 820, is “an embodiment of the present invention” that describes a “possible power saving technique[].” Ex. 1001, 3:30–33, 8:20–25. Similarly, Figure 9A, which includes function block 920, “illustrate[s] one of the possible power saving techniques.” Id. at 3:33–34. The ’330 patent describes that “[f]unctional block 820 . . . may be a filter, mixer, amplifier, or other circuit or circuits in a wireless transceiver or other electronic circuits or system.” Ex. 1001, 8:22–25 (emphasis added). Based on these disclosures, we are not convinced that Function Block 820 or 920 cannot include multiple filters in a Variable Bandpass Filter Block, or that Behbahani’s Variable Bandpass Filter Block does not teach the recited “circuit,” “component,” or “impedance.”” slip op. at 42

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “The absence of meaningful disclosure of the implementation details of the circuit in the ’330 patent suggests that the circuit implementation details Patent Owner argues about now would have been within the understanding of a person of ordinary skill in the art. That is, Patent Owner did not provide in its own specification “the type of detail [it] now argues is necessary in prior art references,” which permits a “finding that one skilled in the art would have known how to implement the features of the references and would have concluded that the reference disclosures would have been enabling.” In re Epstein, 32 F.3d 1559, 1568 (Fed. Cir. 1994). When a patent specification does not “specifically describe[]” any “equipment or techniques to be used,” it may be deduced “that all of the equipment and technical knowledge required to perform the claimed method” is known to one of ordinary skill in the art. In re Fox, 471 F.2d 1405, 1407 (CCPA 1973); see also Southwire Co. v. Cerro Wire LLC, 870 F.3d 1306, 1312 (Fed. Cir. 2017) (without proof to the contrary, when there is no focus on a disputed claim limitation in the specification, the limitation is merely “an observed result of an old process”). To that end, Petitioner provides persuasive testimony from Dr. Abidi that signal strength measurement circuits were known in the art, and that a person of ordinary skill in the art would have understood how to implement a known technique for measuring signal strength, which is not disputed by Patent Owner. Ex. 1003 ¶¶ 180– 181; Ex. 1042 ¶¶ 12–16; see Pet. Reply 24–26; Pet. 60–62. Accordingly, we agree with Petitioner that Behbahani’s disclosure at least suggests circuitry for performing such a determination of signal strength. See Pet. Reply 24 (citing Pet. 60–61; Ex. 1003 ¶¶ 92–98, 179–181). Petitioner further argues that Tan “provides an example of circuitry used to detect signals at various points in the low-pass filter signal path as a means of implementing a prefilter automatic gain control.” Pet. 60–61 (citing Ex. 1006, 481); Ex. 1003 ¶ 180. The example in Tan is a peak detector circuit. Pet. 61; Ex. 1003 ¶ 180; Ex. 1006, Fig. 8. Dr. Abidi testifies that a person of ordinary skill in the art would have been motivated to use Tan’s signal strength measurement circuitry to measure nodes AI and AO. Ex. 1003 ¶ 180. In response to Patent Owner’s argument that Petitioner does not sufficiently explain how to use Tan’s peak detector in Behbahani (PO Resp. 70), Dr. Abidi provides testimony explaining how Tan’s peak detector circuit provides a measure of the signal strength, which we find persuasive, and is unrebutted by Patent Owner.

    “Thus, the parties do not dispute the meaning of “signal path,” and we adopt the district court’s construction of plain and ordinary meaning, as agreed by the parties. See PO Resp. 40–41; Pet. 9; Ex. 2025, 14. The dispute concerns the application of this and the surrounding claim language (i.e., “in the receiver signal path”) to the disclosures in Behbahani. See PO Resp. 40–42. Therefore, we will provide further discussion in the context of the parties’ arguments regarding Behbahani below. However, we agree with Patent Owner’s plain reading of the claim language in limitation 1(e) and the corresponding limitations in independent claims 3, 5, 7, and 8 – i.e., that “[t]he plain language requires adjusting a bias current, or a bias current and an impedance, in a circuit, while it is in the signal path.” See PO Resp. 48. We determine that it is not necessary to provide an express interpretation of any other claim terms for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

  • Settled expectationsNot reached

    “Owner’s] settled expectations in long-standing patent rights, and Office policies and efficiency.” Id.; see id. at 25–26. Patent Owner’s arguments essentially reassert the arguments made in the Preliminary Response that inter partes review should be discretionarily denied under 35 U.S.C. § 314(a) and 35 U.S.C. § 325(d). In the Institution Decision, we were not persuaded by these arguments. Inst. Dec. 15–22. Patent Owner argues that in Ecto World, LLC v. RAI Strategic Holdings, Inc., IPR2024-01280, Paper 13 (PTAB May 19, 2025) (§ A precedential) supports denial under 35 U.S.C. § 325(d). Sur-reply 25. However, Ecto World was designated precedential on May 19, 2025, and our Standard Operating Procedure 2 provides that “[a] precedential decision is binding Board authority in subsequent matters involving similar facts or issues.” SOP2, 7 (emphasis added). Therefore, re-evaluation under Ecto World does not appear to be appropriate under the circumstances here. Patent Owner also argues that proceedings can be properly dismissed post-institution in the Director’s discretion. Sur-reply 26. In support, Patent Owner cites to Hulu LLV v. Piranha Media Distribution, LLC, IPR2024- 01252, Paper 17, at 3 (PTAB April 17, 2025). Id. However, in Hulu, the patent owner timely sought Director Review after the institution decision, and upon Director Review, the institution decision was vacated and denied. IPR2024-01252, Papers 16, 19, 27. By contrast, here, Patent Owner raised this issue for the first time in the Sur-reply (filed August 5, 2025, nearly three months after Ecto World was designated precedential), approximately three weeks prior to oral argument. Patent Owner also did not file a motion to terminate the proceeding. Although we recognize that “that the Board has the inherent authority to reconsider institution decisions (beyond the regulatory time for a patentee’s entitlement to seek reconsideration),” Sling TV, L.L.C. v. Realtime Adaptive Streaming LLC, 840 F. App’x 598, 598–99 (Fed. Cir. 2021), we decline to do so at this late stage in the proceeding.” slip op. at 63

    “Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 3–5 (Director Nov. 3, 2025) (precedential), addressing situations where a petitioner takes different claim construction positions before the Board and a district court. In Revvo, the petitioner advanced its own proposed claim construction in a related district court litigation but adopted in the IPR a different proposed construction, which was advanced by the patent owner in the district court litigation. Revvo at 2. The Director acknowledged that “a petitioner is not necessarily precluded from arguing different claim construction positions before a district court and the Board,” but that if the petitioner does so, it “should explain sufficiently why the different positions are warranted.” Id. at 5. “For example,” the Director explained, “if a party advances a narrow construction in the district court and the district court declines to adopt the narrow construction, the party would have sufficient reason for advancing the broader, court-adopted construction in a proceeding before the Board.” Id. Here, as in the Director’s example, Petitioner advanced a narrower construction of “signal path” before the district court, which the district court declined to adopt. See Pet. 9; Ex. 2015. Instead, the district court adopted a “plain-and-ordinary meaning” construction, which Patent Owner proposed. See PO Resp. 38, 41; Ex. 2015; Ex. 2025, 5–14. In the Petition, Petitioner proposed applying the plain and ordinary meaning constructions that had already been preliminarily adopted by the district court. Compare Pet. (filed May 1, 2024) with Ex. 2015 (preliminarily adopting plain and ordinary meaning construction on March 25, 2024). Applying Revvo, we find that Petitioner had a sufficient reason for advancing the broader, courtadopted construction in this IPR. Thus, the parties do not dispute the meanings of “signal path,” and we adopt the district court’s construction of plain and ordinary meaning, as agreed by the parties. The “signal path” dispute concerns the application of this and the surrounding claim language (i.e., “in the receiver signal path”) to the disclosures in Behbahani. See PO Resp. 41–43. Therefore, we will provide further discussion in the context of the parties’ arguments regarding Behbahani below. However, we agree with Patent Owner that “plain language [of the claims] requires adjusting the impedance (or bias) of a circuit or component in the signal path.” PO Resp. 49. The parties also address the meaning of the terms “dynamically increasing/decreasing,” which Petitioner refers to as the “dynamic limitation.” See Pet. 9; PO Resp. 37–41. Petitioner proposes that the Board accept Patent Owner’s proposed construction, which was adopted by the district court in the related litigation, both preliminarily and following the Markman hearing. See Pet. 9–10; Ex. 2015, 2–3; Ex. 2025, 40. At Institution, we adopted the district court’s construction, that the term should be given its plain and ordinary meaning which is “varying during operation based, at least in part, on information gained during operation,”4 because there was no dispute between the parties. See Inst. Dec. 16. We continue to do so for purposes of this Decision, for the same reasons as set forth above. That is, applying Revvo, we find that Petitioner had a sufficient reason for advancing the broader, court-adopted construction in this IPR.” slip op. at 18

    “both parties have asserted in the Apple Litigation that the “control component” requirement is a means-plus-function limitation subject to 35 U.S.C. §112(f), despite the fact that the control component limitation does not recite “means for.” Pet. 3 (citing Ex. 1012, 3–8; Ex. 1013, 13); PO Resp. 6–7. Indeed, the court in the Apple Litigation has concluded that the control component requirement is subject to 35 U.S.C. § 112(f), and has construed that requirement accordingly: Function: receiving control signals input to the oscillating resonant module; receiving outputs from the one or more sensors; controlling oscillation of the mass to produce a vibration response according to the received control signals by generating, using one or more of the received sensor outputs, control outputs to an actuator that drives the mass to oscillate. Structure: a microcontroller, a processor, a microprocessor, or a CPU that performs the algorithm shown in Figure 45 or the algorithm described in the corresponding text.

  • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

    “(1) Analogous Art Our reviewing court has stated that “[t]wo separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations and internal quotes omitted). While these two criteria are helpful in many instances, we must not lose sight of the key question at hand: what is “prior art” as that term is used in 35 U.S.C. § 103(a)? References that are “too remote to be treated as ‘prior art’” are excluded from the obviousness analysis. In re Sovish, 769 F.2d 738, 741, 226 (Fed. Cir. 1985). The non-analogous art test provides helpful insight on the underlying question of what is “prior art” within the meaning of the statute; we should not, however, be blind to the reality of the circumstances of the case before us. In re Wood, 599 F.2d 1032, 1036 (CCPA (1979). Nor should we adhere to rigid and mandatory formulas that overly limit the inquiry. KSR Int’l Co., 550 U.S. at 419.” slip op. at 22
