“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

“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.

“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.

“spaced configuration are not confined to ferrite cores 32 and 3, and that at least a component of the flux lines will escape the cores. See Ex. 1032 ¶¶ 48–52; Ex. 1038 ¶ 54 Fig. 2. Indeed, the evidence suggests (and Dr. Horenstein acknowledges in his first declaration) that at least a component of flux will escape the core of even a traditional transformer. See Ex. 1032 ¶¶ 45–47; Ex. 1044, 6; Ex. 2001 ¶ 27. In his second declaration, Dr. Horenstein provides contrary testimony that in Odachi’s open configuration during alignment, cores 32 and 3 “act to confine or guide the magnetic flux lines, rather than radiate them into free space,” and “the flux lines would [not] leave the gap area and enter into the space distal to the magnetic circuit.” Ex. 2010 ¶ 69. But in view of Dr. Horenstein’s contrary position in his first declaration, and the lack of supporting evidence in his second, we do not find it credible. 37 C.F.R. § 42.65(a) (2022) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Apple Inc. v.

“(4) Analysis We are persuaded by Petitioner’s argument that during the alignment process in Odachi corresponding to claim 13, there is a “spaced distance between the primary inductive coupler [230] and the secondary inductive receptacle 2” which is “reduced gradually and electromagnetic induction occurs between the coupler to the receptacle when the former coupler comes close to the latter receptacle.” Ex. 1005, 6:1–6. Thus, prior to any contact or precise alignment between the two cores, “an electromotive force is induced in the secondary coil 4 and this induced force is increased with the decrease in the spaced distance.” Id. at 6:6–8. At least in that spaced configuration, the evidence of record suggests that primary coil 31 produces a near-field component of flux into free space (the air space between the coils where there is no intervening core material) that is intercepted by secondary coil 4 to effect resonant inductive coupling, and that secondary coil 4 intercepts and receives the near-field component of flux in free space that is generated by primary coil 31 to effect resonant inductive coupling. See Ex. 1032 ¶¶ 48–52, 55. Thus, we find that Odachi discloses a “transmitting antenna” (coil 31) and a “receiving antenna” (coil 4) under Patent Owner’s proposed construction. We would reach the same finding under Petitioner’s proposed broader construction because the evidence suggests that Odachi’s coils 31 and 4 would have been considered “antennas” under the parties’ uncontested definition of that term, which is “a device that radiates and/or receives radio waves.” See id. ¶¶ 43–47, 53–54; Ex. 1032 ¶ 15 (Dr. Allen agreeing with this definition of “antenna”); Ex. 2001 ¶ 25 (Dr. Horenstein agreeing with this definition of “antenna”)). In addition, Petitioner persuasively shows that the free space between Odachi’s coils in the spaced configuration includes the “near-field region,” which includes the induction field around primary coil 31.

“Petitioner argues that a person of ordinary skill in the art “would have had a bachelor’s degree, or equivalent, in electrical engineering, computer science, or a related field, and 2–3 years of experience researching, designing, or developing content delivery systems and related hardware, software, and firmware, or equivalent experience.” Pet. 4 (citing Ex. 1008 ¶¶ 36–40). Patent Owner does not dispute this. See PO Resp. 3 (citing Ex. 2001 ¶ 22).

“Having considered all the evidence of record relating to Mr. Taniguchi’s activities during the relevant time frame, we find that Patent Owner has not produced sufficient corroborating evidence to show that Mr. Taniguchi’s work on reducing to practice the claimed invention was reasonably continuous during the critical period between September 19, 2008 (the filing date of Ueda), and November 18, 2008 (the filing date of the Japanese patent application). Although there is corroborating evidence of diligence beginning on November 6, 2008, when Mr. Taniguchi transmitted a draft application to the Baba law firm, there is no evidence of any diligence prior to that date, other than Mr. Taniguchi’s own testimony. We do not agree with Patent Owner that the evidence of Mr. Taniguchi’s other activities for NEC, or research relating to IPTV, corroborate Mr. Taniguchi’s reduction to practice of the claimed invention. Although these activities may have something to do with the general subject matter of IPTV, Patent Owner has not shown any nexus between these activities and the challenged claims. See Naber, 567 F.2d at 385 (“It is well settled that, to satisfy the ‘reasonable diligence’ requirement . . . , the work relied on must ordinarily be directly related to reduction to practice of the invention . . . in issue.” (citing cases)). Although Mr. Taniguchi doubtlessly spent substantial time preparing the application he completed on November 6, 2008 (see Ex. 2017), there is no corroborating evidence that this work was reasonably continuous during the critical period. As far as the corroborating evidence attests, Mr. Taniguchi could have done no work on the draft until early November, or he could have worked on the draft briefly in August and put it aside until early November. Considering all the evidence as to Mr. Taniguchi’s activities, we find that Patent Owner has not met its burden of producing corroborating evidence that the named inventors of the ’427 patent exercised reasonably continuous diligence during the critical period when Ueda was filed until the constructive reduction to practice that occurred on November 18, 2008. Therefore, we determine, by a preponderance of the evidence, that Ueda is prior art to the challenged claims.” slip op. at 24
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“In general, we disagree with Patent Owner that, in showing a reason to incorporate the SIP Standard’s teachings about proxy servers, Petitioner must necessarily show that Ueda’s system was deficient or inferior. A patent challenger “does not need to show that there was a known problem with the prior art system in order to articulate the required rational underpinning for the proposed combination.” Unwired Planet, LLC v. Google Inc., 841 F.3d 995, 1002–03 (Fed. Cir. 2016). Also, “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR, 550 U.S. at 416. For this reason and the specific reasons discussed below, we find Patent Owner’s arguments unpersuasive. The evidence of record suggests that it would have been within the ordinary skill in the art to modify Ueda’s system by replacing direct communication between content-providing device 150 and servers 191 or 192 with an indirect connection in the form of proxy servers using well-known, predictable techniques as described in the SIP Standard.” slip op. at 33

“Relying on the testimony of Dr. Hansen, AT&T argues the following: [a]s of the earliest claimed priority date, a person of ordinary skill in the art at the time of the alleged invention of the ’489 patent . . . would have had a [Bachelor of Science] in Electrical Engineering or a related field with at least three years of experience designing, developing, and/or testing telecommunication systems. A [person of ordinary skill in the art] would also have familiarity with the wireless standards and well-known protocols for accessing wireless networks. More education may supplement practical experience or vice versa. Pet. 14 (citing Ex. 1002 ¶ 368). In the Preliminary Response, Innovative Sonic does not address AT&T’s assessment of the level of skill in the art. See Prelim. Resp.

“issue fares no better. With one exception, Dr. Hansen, relies on the same disclosures of the Update for 3GPP TS 36.331 v.9.4.0 to support his testimony, which, as we explain above, does not account for the plain language of the disputed limitation. Compare Pet. 26–27, 43, with Ex. 1002 ¶¶ 87–90. In addition, Dr. Hansen testifies that a person of ordinary skill in the art would have understood that “the E-UTRAN configuring the UE with one or more SCells would necessarily include the configuring of at least one SCell by a source eNB to a UE.” Ex. 1002 ¶ 91 (emphasis added). But neither AT&T nor Dr. Hansen establish inherency in its obviousness analysis. See PAR Pharm., Inc. v TWI Pharms., Inc., 773 F.3d 1186, 1194– 95 (Fed Cir. 2014) (recognizing that “inherency may supply a missing claim limitation in an obviousness analysis,” but limiting the doctrine of inherency “only when the limitation at issue is the ‘natural result’ of the combination of prior art elements” (quoting In re Oelrich, 666 F.2d 578, 581 (C.C.P.A. 1981)). Apart from the conclusory assertion above, Dr. Hansen does not identify sufficient evidentiary support demonstrating that the requirement identically recited in each of independent claims 1 and 12 of “configuring at least one SCell by a source eNB to a User Equipment (UE)” would have been the “natural result” flowing from the Update for 3GPP TS 36.331 v.9.4.0’s disclosure of the E-UTRAN configuring the UE with at least one SCell. PAR Pharm., 773 F.3d at 1195. Accordingly, we do not credit Dr. Hansen’s testimony that implicates the doctrine of inherency because it not supported by evidence of record.” slip op. at 17

“In the Petition, AT&T contends that “the Board does not need to expressly construe any [claim] terms to resolve the arguments presented herein” because the asserted prior art “discloses all limitations under any plausible construction.” Pet. 14 (citing Ex. 1002 (Declaration of Dr. Christopher Hansen) ¶ 456).

“Patent Owner does not contest Petitioner’s proffered definition of the level of ordinary skill in the art, but offers a definition of its own. PO Resp. 8. Patent Owner contends that a person having ordinary skill in the art at the time of the invention “would have had at least a bachelor’s or master’s degree in electrical engineering, computer engineering, electrical and computer engineering, computer science, or similar educational background; or equivalent on-the-job training, including approximately two to three years of experience in machine learning and/or pattern recognition.” Id. (citing Ex. 2008 ¶ 22). Patent Owner asserts that the “level of skill is approximate and more experience would compensate for less formal education and vice versa.” Id. We note that the differences between the parties’ descriptions are immaterial and find Petitioner’s description to be consistent with the problems and solutions disclosed in the ’985 patent and prior art of record, and adopt it as our own for purposes of this Decision, albeit without the two instances of “at least,” which introduce ambiguity.

“Chalom’s large RFC with Aslan’s teacher-student MLA pair would have rendered the ensuing system more complex, and thereby inefficient. As correctly noted by Petitioner, Chalom indicates that the RFC can be embodied in a mobile computing device. Id. at 15 (citing Ex. 1005, 22:33– 37, 19:65–20:6). And Dr. Karam persuasively explains that using the teacher model to train the student model is more efficient because the teacher’s knowledge allows the student model to converge faster. Id. at 17 (citing Ex. 2009, 178:14–24). Accordingly, we find that a POSITA would have found sufficient motivation to replace Chalom’s RFC with Aslan’s teacher-student models to enhance the efficiency of the MLA pair in a mobile computing environment. On this record, we agree with Petitioner that the proposed combination of Chalom and Aslan would predictably result in the teacher MLA generating motion vector fields for user gaze correction (i.e., first reference or editing instructions) that are passed to the student MLA, which subsequently generates motion vector fields (i.e., second reference or editing instructions) for further refining the received first reference data. Id. at 58. Consequently, we reiterate that because the proposed combination involves known elements performing their ordinary functions to produce a predictable result, a POSITA would have appreciated that the proposed combination is proper.4 After considering Patent Owner’s arguments, we find Petitioner has shown by a preponderance of the evidence that the proposed combination of Chalom and Aslan is sufficiently supported by the requisite motivation to teach limitations 1[D] and 1[E].” slip op. at 40

“Because Chalom explicitly indicates that its RFC can be trained using any suitable techniques(s) including compressing the classifier, we agree with Petitioner that a POSITA would have looked to Aslan’s teacher-student architecture that proposes compressing large models such as Chalom’s RFC into smaller models so they can be more readily deployed on computing devices with limited resources. Pet. Reply 11–12. As correctly noted by Petitioner, the experts of the parties agree that both Aslan and Chalom involve classifiers. More particularly, as acknowledged by Patent Owner’s representative during the hearing, compression is desirable for Chalom’s RFC. See Tr. 56:21–57:4. Accordingly, we agree with Petitioner that a POSITA would have looked to a similar compression operation of classifiers in Aslan for training a more compact MLA at runtime or offline. Pet. Reply 11–12. For these same reasons, we find unavailing Patent Owner’s argument that Chalom and Aslan are directed to different objectives or techniques. Further, we do not agree with Patent Owner’s argument that replacing Chalom’s large RFC with Aslan’s teacher-student MLA pair would have rendered the ensuing system more complex, and thereby inefficient. As correctly noted by Petitioner, Chalom indicates that the RFC can be embodied in a mobile computing device. Id. at 15 (citing Ex. 1005, 22:33– 37, 19:65–20:6).
