    “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

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

    “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

Petitioner also argues that “[a]dditional experience could substitute for a formal degree or formal training (and vice versa).” Id. Patent Owner proposes a slightly different level of skill, arguing that a person of ordinary skill in the art “would have had a bachelor’s degree in Mechanical Engineering, Computer Engineering, Chemical Engineering, Materials Science, or a comparable field and at least two years of experience related to 3D printing, with additional experience potentially being a substitute for a formal degree or training (and vice versa).” Prelim.

    “According to the ’713 patent, “[p]urge tower 24 itself may be . . . recycled or otherwise discarded as desired.” Ex. 1001, 8:27–28. This description provides some support for Patent Owner’s view, because a purge tower too intimately integrated with the part would be difficult or impossible to recycle or discard. This is further supported by the ’713 patent’s statement that “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Id. at 8:30–34. It also is supported by Dr. Hickner’s testimony that the ’713 patent “clearly shows . . . the 24 purge tower separated from the part” and that “the purge tower is a separate physical object.” Ex. 2016, 28:8–10, 64:1–9. On the other hand, there is evidence supporting Petitioner’s view that, as long as the purge tower is generally separate from the part and the support structure, it may still make contact with those portions of the print. As noted above, “purge tower 24 may be printed at any suitable location on build substrate 44 (i.e., at any location in the x-y build plane not occupied by 3D part 20 or support structure 22).” Ex. 1001, 8:30–34. This language does not exclude locations adjacent to or in contact with the part or the support structure. Thus, determine that a “purge tower,” as that term is used in the context of the ’713 patent, may not be an integrated portion of a printed part or support structure but need not be free of all contact with the printed part or support structure.” slip op. at 9

  • BurdenNot shown unpatentable

    “There is evidence of record to support both Petitioner’s view and Patent Owner’s view. On the record developed at trial, however, we cannot say that the preponderance of the evidence favors Petitioner, who bears the burden of proof. See 35 U.S.C. § 316(e). Accordingly, Petitioner has not shown by a preponderance of the evidence that KISSlicer teaches printing a layer of a purge tower each time the printer switches one extruder to the operating mode. Because proving the obviousness of claims 1 and 16 requires such a showing, Petitioner has not shown by a preponderance of the evidence that claims 1 and 16 would have been obvious over the combination of Priedeman and KISSlicer. 5. Analysis of Remaining Claims Claims 2, 6, 7, 9, and 17 all depend, directly or indirectly, from claim 1 or claim 16. Accordingly, they all include the limitations of either claim 1 or claim 16. Because, as discussed above, Petitioner has not shown that the combination of Priedeman and KISSlicer teaches or suggests all the limitations of claims 1 and 16, Petitioner also has not proven by a preponderance of the evidence that claims 2, 6, 7, 9, and 17 would have been obvious over that combination of references.” slip op. at 21

    “Based on the record before us, we agree with Petitioner that “on a surface” should be interpreted in line with the definition of “on” set forth in the ’711 patent. Ex. 1001, 4:1–6. We particularly note that the ’711 patent states that “‘on’ . . . should be interpreted in the broadest manner” and that “on” is not limited to “directly on.” Id. Instead, the ’711 patent states that “‘on’ also includes the meaning of ‘on’ something with an intermediate feature or layer therebetween.” Id. Patent Owner agrees that this definition controls the “standalone ‘on’” term such that A may be on B even if there is an intervening layer between them. Tr. 55:8–11 (“The standalone ‘on,’ we agree in the context of the patent, you can have intervening layers. I think the patent is clear about that.”). Claim 14 recites that the etch-stop layer is “on” something; i.e., “on a side surface and a top surface of each step.” Ex. 1001, 16:20–22. Patent Owner agrees that a surface is a “something.” Tr. 56:5–8 (“surface obviously is a something”). Substituting the “a “‘on’ something with an intermediate feature or layer therebetween” results in claim 14 reading as, “on a surface with an intermediate feature or layer therebetween.” Unlike “directly on,” which specifies the relation between two things, “a surface” may merely indicate the thing that something is “on,” particularly when “on” is “interpreted in the broadest manner” as expressly required by the ’711 patent.” slip op. at 7

    “Although Dr. Campbell testified in his deposition in response to Petitioner’s counsel that “on the surface” requires direct contact with the surface, his interpretation was based on “embodiments of” the patent rather than a general understanding of a person skilled in the art confronted with that term. Ex. 1027, 122:6–25, 124:6–23 (“I’m not sure if there are other sources for that, but it was on the ’711, so I’ve taken it there.”). Dr. Campbell, upon questioning from Patent Owner’s counsel, later stated that “an expert in semiconductor fabrication” would understand “on the surface” to mean “contact between one layer and another . . . with nothing in between.” Id. at 146:25–147:6. However, Dr. Campbell did not explain why such an interpretation is particular to the semiconductor fabrication art, or provide other explanation or support for this statement, which is in tension with the definition of “on” in the ’711 patent. Accordingly, we significantly discount the weight accorded to that statement. Phillips, 415 F.3d at 1318 (stating, “conclusory, unsupported assertions by experts as to the definition of a claim term are not useful to a court. Similarly, a court should discount any expert testimony ‘that is clearly at odds with the claim construction mandated by the claims themselves, the written description, and patent.’”). On balance, Dr. Campbell’s testimony is best understood as a description of certain Figures of the ’711 patent rather than a representation of an ordinarily skilled person’s understanding of the term “on the surface.” See Ex. 2009 ¶ 47 (describing Figs. 1, 3, and 4 as depicting layers in contact with the underlying layer or substrate). For example, Dr. Campbell describes Figure 9A as having a barrier layer “on and directly contacting the top and side surfaces of each step.” Id. ¶ 28 (emphasis added) (citing inter alia Ex. 1001, 7:6–67). Dr. Campbell does not explain why, beyond the fact that many Figures show layers as adjacent and in contact, a person of ordinary skill in the relevant art would understand those Figures to limit the claim language rather than illustrating particular embodiments that fall within a broader scope of claims 14 and 15. See Hill-Rom Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed.

    “We agree with Petitioner that Kim’s first and second section are described as compatible, not mutually exclusive, embodiments. Kim’s second section builds further layers upon the structure of its first section, and states: In these embodiments, the same elements as in the embodiments previously described with reference to FIGS. 5A through 14A and FIGS. 5B through 14B will be denoted by the same reference numbers therein, and for concise description, overlapping description of elements previously described with reference to FIGS. 5A through 14A and FIGS. 5B through 14B may be omitted. Ex. 1005 ¶ 184 (emphasis added). Patent Owner argues that only the embodiments in Figures 17A–22B describe an etch-stop layer and a barrier layer (as claimed), and that the language cited for a gate-stack-on-top configuration (e.g., Ex. 1005 ¶¶ 90, 91, and 240) is “conspicuously absent from the description of Figures 17A–22B.” PO Resp. 20 (citing Ex. 2009 ¶ 36). However, Figures 17A–22B do not further address the underlying staircase structure that was detailed in the descriptions of the Figures 4 through 15 embodiments. While Figures 17A–22B show a gate-stack-on-bottom configuration, this merely continues the gate-stack-on-bottom illustrations that were used in all of the previous Figures, even for those in which it is undisputed that a gate-stack-on-top configuration is a described alternative.

    “We are persuaded by Petitioner that the lower volume of Toyama’s dielectric fill portion teaches the isolation structure and the upper volume of Toyama’s dielectric fill portion teaches the dielectric structure. First, the structure may be the same material; i.e., SiO2. Ex. 1001, 10:37–40 (isolation structure 233 filled with SiO2), 10:46–47 (dielectric structure can include SiO2, and can include the same material as dielectric layer 230), 10:12–14 (dielectric layer 230 is formed of SiO2). Second, the ’378 patent indicates that the dielectric structure may be “aligned to” and “in contact with” the isolation structure. Id. at 10:30–36. Thus, the two structures of the ’378 patent may appear as two aligned and contacting structures; e.g., a single column of the same material. Third, the ’378 patent specification describes that the dielectric structure and a top portion of the isolation structure may be formed in the same deposition step. When etching the opening 600 that is to be filled with dielectric structure 232, “opening 600 may extend partially into STI structure 233;” i.e., “the etch process used to form opening 600 may also remove (recess) portion of the top surface of STI structure 233.” Id. at 15:12–20; Fig. 6. Then, “opening 600 can be filled with a dielectric layer 702,” which may be the same SiO2 material as the isolation structure, and “[a]s a result, dielectric structure 232 is formed.” Id. at 15:42–54. Thus, the ’378 patent describes a dielectric structure that partially replaces or re-forms, with the same material, its isolation structure. The ’378 patent does not mention whether this results in a dielectric structure that extends into the isolation structure or an isolation structure re-filled to its original height, and it would not appear to matter because both structures may be composed of the same material. The ’378 patent’s indifference to the exact boundary between dielectric structure 232 and isolation structure 233 during formation from the same material indicates that these structures need not be taught by distinct elements. applicable only if the ’378 patent describes that the isolation region and dielectric structure were formed as a single unitary structure.

Retractable Techs. looks to whether the specification suggests that the claim terms require separate structures. Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1232 (Fed. Cir. 2011). Patent Owner’s focus on whether the claimed structures were disclosed as being separately formed disregards the issue of whether the separately claimed structures require specific methods of forming those structures. Here, as in Retractable Techs. and Powell, the Specification does not indicate any particular structure or function for the structures that results from their separate steps of deposition. Thus, as held in Retractable Techs. and Powell, the two portions of Toyama “need not be two separate parts” to teach two separate claim limitations. Retractable Techs., 635 F.3d at 1303–04. Consequently, we determine that the claim language does not support a requirement that these structures be separate and distinct. Patent Owner’s further arguments are not availing.

Id. Nor have the parties indicated, in response to Board inquiry, that any relevant construction has occurred. See Paper 34. with Petitioner that Patent Owner does not dispute this aspect of the “a dielectric structure on the isolation structure” limitation in Petitioner’s assertions based on Toyama. PO Sur-reply 20–21. Patent Owner does dispute that Mushiga’s insulating spacer 586 is “on” the isolation structure. PO Resp. 70–72. However, because Petitioner relies upon a dielectric structure that includes other portions of Mushiga that Patent Owner does not dispute to be on the asserted isolation structure, the dispute is whether Petitioner is correct to include multiple components as part of a single dielectric structure, and not whether spacer 586 is on an isolation structure. Id. Because Petitioner’s assertions and our determination would be unaffected by its proposed construction, we need not construe this term. See Nidec Motor Corp. v.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “Patent Owner’s citations to the Specification do not support its proposed construction. Patent Owner relies on multiple embodiments, only one of which describes a substrate “with” an isolation structure. PO Resp. 21 (citing Ex. 1001, 22:27–28). For example, one of Patent Owner’s cited embodiments recites “on” an isolation region, but Patent Owner specifically argues that the “on” embodiment does not apply to the claimed “with” embodiment. Id. at 22 (denying that “the ‘with’ relationship encompasse[s] the ‘on’ relationship”). Only one of the embodiments cited is clearly within the scope of the “with” claim language, and that embodiment describes no more than the claim language itself. Ex. 1001, 22:27–28. Moreover, Figure 2, cited by Patent Owner, is an illustration “according to some embodiments,” but is not described as depicting all embodiments. Ex. 1001, 3:35–36. These other embodiments need not be included in claim 15’s “with” language because other claims (not at issue in this proceeding) specifically recite language from other embodiments. Ex. 1001, 23:20–21 (“a dielectric structure on an isolation region of the substrate”), 23:58 (“forming an isolation structure on a substrate”). Thus, the specification of the ’378 patent does not limit “a substrate with an isolation structure” in claim 15 to “part of” an isolation structure, such as in a shallow region or other partial-depth portion of the substrate. Because neither the language of claim 15 nor the Specification indicates a narrower meaning, we agree with Petitioner that the phrase “a Patent Owner argues that the plain meaning of “with” is “having” or “inclusive of.” PO Sur-reply 2 (citing Ex. 1038, 7).

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
