    “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

    “understanding that the claim term “from bottom to top” refers to the vertical arrangement of word lines in the memory portions from bottom to top and not from source end to drain end, as asserted by Petitioner. Inst. Dec. 17. In other words, the claim terms describing the first and second portions having word lines “from top to bottom” refer to the relative vertical location of the word lines within the memory portions and not to location of the word lines relative to the source or drain. Our construction is based on the plain and ordinary meaning of the express language of the independent claims, which states that the second memory portion is formed either above or below the first memory portion. The forming of one memory portion above or below another portion establishes a top and bottom in relation to those portions. For example, claim 5 is directed to a “program method of memory” that requires a second portion formed above the first portion. A second memory portion that is formed above a first memory portion is on top relative to the first portion. Similarly, claims 1 and 1 and 11, which recite a memory having a second portion formed below a first portion, establish that the second portion is on the bottom relative to the first portion. Thus, the claim language itself establishes the vertical locations of the memory portions relative to each other (e.g., a second memory portion that is above the first portion is on top, relative to the first portion). It follows that claim terms referring to the top and bottom of word lines within the memory portions also refer to relative vertical locations of the word lines within the memory portions.

Kim’s Figures 17A–22B do not further address the underlying staircase structure that was detailed in the descriptions of the Figures 4–15 embodiments.

However, as admitted by Patent Owner, all of Kim’s Figures show only a gate-stack-on-bottom structure. Tr. 41:6–7 (“For the first embodiment, it is true that figures show the gate stack on bottom.”). The fact that Kim’s Figures 17A–22B, which add etch-stop and barrier layers to the gate stack, are shown only as gate stack on bottom is merely consistent with the uniform use of gate-stack-on-bottom in Kim’s Figures, which show the layer-by-layer construction of its device. Like Figures 4–15, Figures 17A–22B exemplify rather than limit the description of the previously described memory stack, and do not exclude the gate-stack-onbottom description of the memory stack. Kim can be used for all it realistically teaches, including descriptions in its disclosure that are not represented by specific Figures.

As set forth above, Dr. Foty describes the three ground lines in Saint Figure 7-7 as “segmented rails” when discussing the combination of Saint and Haralabidis, thus equating the three ground lines in Saint Figure 7-7 with Haralabidis’ segmented ground rail. Ex. 1003 ¶ 368. Neither Petitioner nor Dr. Foty, however, adequately addresses how or why a POSITA would have understood that the three separate grounds lines in Saint Figure 7-7 were “segmented rails” like the segments of the single ground line described in Haralabidis. In contrast, Dr. Khatri credibly testifies: Haralabidis teaches the use of a “common ground rail” to connect “segmented ground rails.” Haralabidis, 3:9–22, 3:34– 40, 3:65–4:12. A POSITA would understand “segmented ground rails” to refer to a single ground signal that has been “segmented.” That is fundamentally different from the design of Saint’s Figure 7-7 that Dr. Foty relies on, which uses three different ground signals, GND1, GND2, and GND3—not a single ground signal that has been “segmented.” Because of that, a POSITA would not have been motivated to change the Figure 7-7 design completely to connect three separate signals (GND1, GND2, and GND3) together as Dr. Foty proposes. Ex. 1003 ¶ 368. Indeed, for these reasons, a POSITA would have understood Haralabidis’ teachings of a “common ground rail” are inapplicable to Saint’s Figure 7-7. Ex. 2010 ¶ 129.

Because all of Yoshinaga’s illustrated pads are power supply pads, Petitioner’s proposed reassignment of pads would not be a simple matter of rearrangement of an existing mixture of power supply and reference pads, but require that reference pads be imported from elsewhere, and power supply pads be moved to some unspecified location. Petitioner’s arguments and Dr. Foty’s testimony with respect to the modification of Yoshinaga Figure 6 leave an analytical gap that does not apprise us of why a POSITA would have modified Yoshinaga Figure 6 to include reference pads in the place of power supply pads 3, 4, and 58.

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

    “From the outset we note that the words of the claim recite “non- uniformly shift[ing] the pixels” and do not recite a “non-linear” transformation. This favors Petitioner’s position, which is based directly off the definition of “non-uniform,” over Patent Owner’s position, which substitutes “non-linear” for “non-uniform.” Generally, then, we would determine the ordinary and customary meaning of the claim term in the context of the entire Specification. Here, however, the ʼ413 patent does not mention “uniform” or “non-uniform” shifting of pixels anywhere except in the claims. The Specification, therefore, provides limited guidance, by itself, as to the ordinary and customary meaning of the term. Nonetheless, even reviewing the portions of the Specification cited by the parties, we see no clear or unambiguous effort to limit the challenged claims to require only non-linear transformations in which the pixels to which a transformation is applied do not have the same amount of shift. is not non-linear. Pet. Reply 1. Specifically, Petitioner argues that the center circle of Figure 2B maintains the original circular shape after the transformation is applied to the image which contradicts Patent Owner’s argument that no two pixels will have the same amount of shift. Pet. Reply 1–2. We agree. In Figure 2B of the ʼ413 patent, the center of the image is chosen to be the region of interest. Ex. 1001, 4:19–21. After the input image goes through linear scaling (step 204) and then non-linear warping (step 206) the circles become more vertically compressed as they approach the top and bottom edges and more horizontally stretched as they approach the left and right edges. Id. at 4:22–30. But “the center circle is fully corrected so that it maintains the original circular shape of the corresponding circle in the input image 212.” Id. at 4:23–25. This means that at least some pixels, such as those of the center circle, undergo the same amount of shift after being transformed.” slip op. at 11

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

    “readable instructions” of claims 1 and 2 must occur in a particular order. Specifically, Patent Owner argues that the step of “determine a portion within the input image” must occur after “obtain[ing] an image” and before “apply[ing] a transformation to the input image.” PO Resp. 17 (citing Ex. 2027 ¶ 59). Petitioner argues, on the other hand, that the specification does not require such an order and, in fact, describes an embodiment where such an order is not followed. Pet. 3. We determine that the “determine a portion within the input image” step does not need to occur after the “obtain an image” step and before the “apply a transformation to the input image” step. As Patent Owner itself points out, claims 1 and 2 are apparatus and system claims respectively, and an ordering of the limitations of such claims is not necessary. PO Resp. 17. Even if we were to treat the apparatus and system claims as reciting the steps of a method, “as a general rule the claim is not limited to performance of the steps in the order recited, unless the claim explicitly or implicitly requires a specific order.” Baldwin Graphic Systems, Inc. v. Siebert, Inc., 512 F.3d 1338, 1345 (Fed. Cir. 2008) (citing Interactive Gift Express, Inc. v. Compuserve Inc., 256 F.3d 1323, 1342–43 (Fed. Cir. 2001)). We see nothing in the claims that would cause us to break this general rule. Patent Owner argues that the claims imply a “specific order because the ‘determine a portion’ requirement operates on ‘the [obtained] input image’ and defines the ‘portion’ that is necessary for the 23; Ex. 2027 ¶ 59). Although the steps are recited in a specific order in the claim, as they necessarily must be, the claim does not expressly specify that the certain steps must occur before or after other instructions, nor does logic imply such a requirement. For example, if certain characteristics of the image are known before the image is obtained (e.g. the size, dimensions, resolution, aspect ratio, or content etc.) the determination of the portion of the image could be made before the image is obtained. These characteristics may be based on the specific device taking the image or the subject matter of the image, both of which may be known before the image is captured or obtained. It is, therefore, not necessary that the image be obtained in order for a portion of the image to be determined. Similarly, we do not find the written description to expressly or implicitly specify an order the claimed step of “determine a portion of the input image.” For example, the written description of the ʼ413 patent states that in Figure 2B “the center of the image is chosen to be the region of interest that is most fully corrected and the distortion increases in each direction as the frame boundary is approached.” Ex. 1001, 4:19–22. Patent Owner emphasizes that this disclosure implies that an input image is obtained before the center portion is chosen. PO Resp. 19 (citing Ex. 1001, 3:63–64, 4:19–22). But the description of this embodiment does not expressly recite an order. For example, the description of Figure 2A explains that “an input image is obtained” in step 202, “the image is then scaled” in step 204, and a “non-linear warping is then applied” in step 206. Ex. 1001, 3:63–4:3. This description does not mention “determin[ing] of a portion of the image” as a separate step or as part of the listed steps, and therefore, does not specify an order in which this step must occur. is configured so that some areas of the image are fully corrected geometrically, while some other areas are distorted. . . . [T]he center of the image is chosen to be the region of interest that is most fully corrected and the distortion increases in each direction.” Id. at 4:17–19. This excerpt from the ʼ413 patent, which the Patent Owner specifically relies on (PO Resp. 19), also does not specify an order in which the determination step (choosing of the region of interest) takes place. Moreover, because the ʼ413 patent states that the warp module is configured so that some areas are fully corrected while others are not, the determination step could take place at the time the warp module was configured, presumably before the image was obtained. Finally, the ʼ413 patent states that “in the case, of video, the area may dynamically change between images (e.g. to follow a moving object).” Ex. 1001, 4:34–36. Patent Owner argues that this description “requires first obtaining the image in order to locate the object that is being followed.” PO Resp. 19–20. This embodiment is related to the case of video or a moving object, which the challenged claims do not mention. We, therefore, decline to limit the scope of the claim based on this embodiment. Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed.

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

    “Having reviewed the parties’ arguments and cited evidence we determine Petitioner has established, by a preponderance of the evidence, that a POSITA would have been motivated to combine Meulen and Chao. For example, Petitioner argues that “[i]t would have been obvious that when performing image scaling, pixels from the input to output positions are shifted based on a scaling factor.” Pet. 91. Meulen teaches scaling but does not provide the details regarding scaling. E.g., Ex. 1007, 1:55–56, 4:37–49. We agree that in light of Meulen’s disclosure of scaling, a POSITA would have looked to other references, such as Chao, for further details on how to perform scaling. Dr. Katsaggelos provides credible support, testifying that “Meulen mentions ‘compression and/or scaling,’ and provides details on how to perform compression. But Meulen does not disclose the details of how to perform scaling. A POSITA when faced with Meulen and having the knowledge about scaling would have been motivated to turn to a prior art reference that discloses the details of scaling.” Ex. 1002 ¶ 262. Patent Owner argues that Petitioner provides no motivation to combine other than asserting that it involves combining prior art elements. PO Resp. 35 (quoting Pet. 92). As explained above, however, Petitioner does more than just assert that the motivation involves combining prior art elements. Instead, Petitioner explains that Meulen discusses both compression and scaling, and provides details regarding compression but does not provide details on how to scale. Pet. 91–92; Ex. 1002 ¶¶ 262–262. Thus, Meulen teaches that scaling was a known technique. See Hybritech, (“a patent need not teach, and preferably omits, what is well known in the art”). Dr. Katsaggelos testifies that, in this situation, a POSITA would have looked to Chao for details regarding scaling. Ex. 1002 ¶¶ 262–263. We determine this establishes, by a preponderance of the evidence, that a POSITA would have had reason to combine Meulen’s teachings with Chao. Patent Owner draws a distinction between Meulen and Chao, arguing that “Meulen is concerned with modifying content from a media source to be displayed on a device’s screen while Chao, by contrast, is directed to changing the aspect ratio of a document intended for printing.” Id. at 36 (citing Ex. 2027 ¶¶ 89–90). Patent Owner’s argument is contradicted, however, by Chao’s disclosure which states that “after all the background and foreground elements in the image have been resized . . . [t]he image may be output by displaying the image on or as part of: a display screen such as a computer monitor, camera screen, printer screen, printed page, projected image, or the like.” Ex. 1008 ¶ 32. Patent Owner argues that Meulen’s system avoids distortion near the middle where the user’s focus is more likely to be, while Chao, on the other hand, is directed to avoiding distortion of stylized borders on differently sized pages. PO Resp. 36–37 (citing Ex. 1006, 1:26–29; Ex. 1008 ¶¶ 1, 25; Ex. 2027 ¶¶ 91–92). This argument reads the prior art too narrowly and does not address Petitioner’s combination. Petitioner does not rely on Chao for its teaching of avoiding distortion near the borders of the image, but rather on its teaching of scaling the image while maintaining the design intent of the original image. Ex. 1008 ¶ 22; Ex. 1014 ¶ 67. Thus, Petitioner is applying Chao’s techniques of scaling (regardless of where the area of 92. Finally, Patent Owner argues that Chao’s approach of stretching/shrinking only the background and uniformly scaling entire foreground objects is suitable for graphic design but incompatible with Meulen which is concerned with adapting externally derived media source content for display on a fixed size screen. PO Resp. 37–38 (citing Ex. 2027 ¶ 93). We disagree with Patent Owner’s argument because it does not address Petitioner’s combination. Petitioner relies on Chao’s teaching of stretching/shrinking of background elements and applies that stretching/shrinking to Meulen’s images displayed on its screen. Pet. 91–92 (citing Ex. 1008 ¶¶ 28, 63; Ex. 1002 ¶ 263). The fact that Chao applies its teaching to graphic design does not prevent a POSITA from applying those teachings to Meulen’s media content displayed on its screen.” slip op. at 20

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

    “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

Given Sciencons AS’s representation that ARTBIO, Inc. is currently the exclusive licensee of the ’437 patent and is responsible for defending the ’437 patent, we grant Sciencons AS’s unopposed request that ARTBIO, Inc. be included in the caption. For convenience we refer to Sciencons AS and the purported exclusive licensee ARTBIO, Inc. collectively as “Patent Owner.” As stated supra, to the extent any party disputes ARTBIO, Inc.’s right to participate in this proceeding or to be included in the caption, the party shall request authorization to brief the issue within 10 business days of this Decision.” slip op. at 3

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
