“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.

“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

“In response, we conclude that the most natural reading of limitation [l] results from examination of the entire limitation: “locating encryption information that identifies encrypted portions of frames of video within the requested portions of the selected stream of protected video.” Ex. 1001, 27:54–57. The “within” most naturally connotes where the encrypted portions of frames of video occur, as opposed to determining where the encryption information may be located. Patent Owner’s interpretation is not wrong, i.e., the limitation could be read as Patent Owner suggests, leading to a narrower construction, but we are not persuaded that the construction of limitation [l] must be so limited, on the basis of the words themselves. We continue to reject Patent Owner’s interpretation that limitation [l] requires locating encryption information within the requested portions of the selected stream of protected video. See Inst. Dec. 27–30; 1st Final Dec. 8. Although it is apparent that encryption information can be found within the requested portions, we are not persuaded that the claim language or ’588 Patent implicitly or explicitly requires such a relationship. Likewise, although embodiments disclosed in the Specification of the ’588 Patent are consistent with Patent Owner’s more restrictive construction, the Specification also is consistent with the more grammatically correct construction as well. Thus, we construe limitation [l] as requiring that the encrypted portions of frames of video be within the requested portions of the selected stream of protected video, but we do not construe limitation [l] as requiring that the encryption information be within the requested portions of the selected stream of protected video.” slip op. at 15

Petitioner does not explain how filling in a gap between the isolator 100 and a substrate necessarily results in “each of the plurality of optical isolators [being] disposed substantially in parallel relative to each other,” as recited in claim 1. The cited portion in paragraph 43 references Figures 5 and 6, which depict Embodiment 1 of Wang and are reproduced below. Figures 5 and 6 of Wang depict isolators 100, base 311, and baffles 312. Although paragraph 44 of Wang states that “[t]he substrate includes a base 311, and baffles 312 and isolators 100 sequentially disposed on the base 311,” Petitioner does not sufficiently persuade us how Wang’s disclosure “sequentially disposed” isolators necessarily discloses that the isolators are “disposed substantially in parallel relative to each other” as recited in independent claim 1. Ex. 1006 ¶ 44. Although the cited portion in Figure 6 of Wang apparently shows a possibly parallel arrangement of Petitioner cites to Dr. Kirk’s Declaration, but Dr. Kirk does not opine on why cited portions of Wang necessarily disclose or depict the claimed “disposed substantially in parallel relative to each other” requirement.

“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

“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.

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. Cir. 2005) (en banc) (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments.”).” slip op. at 14
- 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

“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.

“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

“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
