- 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

“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. 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

“Therefore, the specification clearly links the function of “control[ing] supply of power from the power supply to . . . cause the moveable component to oscillate at a frequency . . . specified by one or more stored values” at least to portions of steps 706 and 708 of the flow diagram algorithm of Figure 7A, as described above. Thus, the control component requires a microprocessor and memory with algorithmic structure including a timing algorithm or similar coding for creating a control output signal that flips to control the direction of current flow through a coil (e.g., coil 514, Fig. 5, coil 626, Fig. 6), where the coil is structure that corresponds to the recited “driving component,” as noted above.11 We adopt the District Court’s conclusion in the Apple litigation that the “control component” structure itself does not require an H-bridge switch, but only requires that the processor generates the “d” inputs to the switch; and further that the structure does not require does not require computing initial default values as specified in step 702 of Figure 7A (i.e., values not specified by a user). Ex. 3001, 30–33, 35. This is in accord with settled law 11 “Rather than using a formal timer mechanism, certain implementations may simply employ counted loops or other simple programming techniques for periodically carrying out tasks.” Ex. 1001, 7:17–20. that limits the structure to that necessary to perform the claimed function. 12 By the same token, we modify the District Court’s construction to the extent it would require, based on such steps as 706, 710, and 716, a specific order of the steps of generating the “p” and “d” values. The claims only require the control component to control the power supply to cause oscillation at a specified frequency and amplitude, but do not require the frequency value to be generated before the amplitude value, or vice versa.” slip op. at 18

Pet. 46–47 (citing Ex. 1006 ¶¶ 15, 25– 28, 37; Ex. 1003 ¶¶ 192–193). Petitioner argues that this combination would have been motivated by the desire to expand the functionalities of haptic devices to allow end users to create and customize haptic effects, to provide a fuller haptic experience, and to be able to store haptic effects to save processing power compared to real-time generated effects. Id. at 47–49 (citing Ex. 1006 ¶¶ 14–15, 30, 47, 53–57; Ex. 1003 ¶¶ 194–196). Petitioner argues that this making combination would have had a reasonable expectation of success given that both references deal with linear actuators, both disclose storing frequency and amplitude values, and the combination involves routine knowledge of software techniques.

Petitioner further argues that it would have been obvious to use the H-bridge switch of Rossi as part of the Gregorio actuator drive circuit 16 in the asserted Gregorio-Ramsay combination to periodically switch the polarity of drive signals to electric coil 28 of Gregorio, and thus oscillate magnet 27, under the control of a signal from processor 12 of Gregorio. Pet. 56 (citing Ex. 1003 ¶ 211). Petitioner argues that this combination would have been motivated because Gregorio does not disclose implementation details and therefore one of ordinary skill would have looked toward teachings like Rossi to fill in those details, and that an H-bridge switch was a well-known example circuit for implementing a change in “current flow direction/polarity” for “push” and “pull” actions in a system, and was a simple, cost-effective, and reliable circuit design.

Id. at 58 (citing Ex. 1003 ¶ 218). Petitioner further argues that it would have been obvious to modify the Gregorio-Ramsay-Rossi combination, using the control algorithm disclosed in Aldrich, to replace the monitoring technique of Gregorio with that of Aldrich to maintain a resonance frequency by incrementing or decrementing the drive frequency. Pet. 58–59 (citing Ex. 1004, 4:22–28, 4:42–48; Ex. 1021, 2; Ex. 1003 ¶ 219).

Id. at 59–60 (citing Ex. 1021, 2; Ex. 1003 ¶¶ 220–222).

“declaration addresses the Patent Owner Response and is relevant to the issues at hand.

“The facts above are evidence of the Krames reference’s publication as of June 29, 2000, because the facts tend to make the Krames reference’s publication as of June 29, 2000, more probable than it would be without the evidence. See Fed. R. Evid. 401(a) (defining evidence as relevant “if it has any tendency to make a fact more or less probable than it would be without the evidence”). The evidence is sufficient to support publication. Meanwhile, no evidence of record suggests that Krames was not a printed publication as of June 29, 2000. Thus, a preponderance of the evidence supports Krames’s prior art status. Patent Owner argues that Ms. Watters “never establishes a firm date when Krames was purportedly available to the relevant public.” Resp. 21.

“In the Reply, Petitioner uses the Krames declaration (Ex. 1028) to argue, for example, that a person of ordinary skill in the art would have used a lower amperage than the 1.5 A dc that Patent Owner’s Response focuses on. Reply 8 (citing Ex. 1028 ¶ 22). This use of the Krames declaration is timely because it responds to an argument Patent Owner makes in the Patent Owner Response. 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in . . . patent owner response.”). As to relevancy and whether the Krames declaration is applicable to the facts of this case, the issues at hand are (1) whether or not a person having ordinary skill would have had reason to use the Krames LED with Begemann with a reasonable expectation of success and (2) whether or not the Krames LED is capable of outputting light at greater than about 40 milliwatts. Again, we emphasize that claim 21 does not recite a method where the LED within the recited semiconductor light source actually outputs greater than about 40 milliwatts. The Krames declaration is relevant to the facts of this case because the declaration has bearing on whether or not a person of ordinary skill in the art would have combined the Krames reference’s LED with Begemann’s lightbulb design. See, e.g., Ex. 1028 ¶ 22. Patent Owner argues that evidence must be relevant to motivation to combine “an LED chip from the Krames article (operating at 1.5 amps to produce 170 milliwatts of output)” but claim 21 has no “operating at 1.5 amps to produce 170 milliwatts of output” requirement. What is relevant is that Krames discloses a single chip that has the capability of outputting more or less light depending on operating conditions. Pet. Opp. 3; see also Ex. 1008, 8 (providing that Figure 12 of the Krames reference is described as illustrating “[l]ight output vs. current characteristic of a blue … 1x1 mm2 AlGaInN LED in a power package, compared to a conventional AlGaInN LED in a 5 mm lamp a package”). Because claim 21 does not require actually running the recited LED at any particular wattage or amperage, it is appropriate for the Krames declaration to rebut Patent Owner’s argument that a person of ordinary skill would not have considered using the Krames LED with Begemann at high amperage by explaining that a person of ordinary skill in the art would have considered using the exact same Krames LED with Begemann at a low amperage instead and that at this lower amperage the Krames LED would generate an amount of heat that would be easily dissipated by Begemann’s lamp while still providing an optical output of “greater than about 40 milliwatts” as recited by claim 21. Ex. 1028 ¶¶ 23–24 (citing Ex. 1008, 8). The fact that the Krames LED is configured to run at the high amperage if desired for a different application does not negate the rationale for combining the Krames LED to run at a lower amperage.” slip op. at 14

The Figure 1 apparatus, at the location of the purple oval, merely conveys a strobe signal (gwlstrbuf 20) on a line without substantially changing that signal. Id. Fig. 1. The Figure 2 apparatus, however, illustrates main amp strobe 60 generating output signal 88 by delaying the gwlstrbuf signal output by buffer 58. Id. at 4:6–9, Fig. 2. Given the context of the ’429 patent specification, we decline to construe “main amplifier strobe” in a manner that would fail to distinguish Figure 2’s main amplifier strobe from Figure 1’s unlabeled strobe-carrying line (identified with a purple oval above). See id. (identifying main amp strobe 60 as a “main amplifier strobe circuit 60”). If Figure 2’s identification of a “main amplifier strobe 60” is to be distinguishable from Figure 1’s lack of any identified main amplifier strobe 60, the main amplifier strobe has to be more than just a mere strobe signal or line that carries a strobe signal. The ’429 patent specification explains that “first main amplifier strobe circuit 60 delays the rising edge of the output of the buffer 58” to “ensure[] that the local amplifiers 82, 84, 86 stay on until the main amplifier 108 is on.” Id. at 4:6–9. While we decline to import this exact functionality from the specification into claim 1’s “main amplifier strobe,” based on the discussion above, the main amplifier strobe must affect the transmitted signal and it must affect the signal consistent with the word “strobe.” See Phillips, 415 F.3d at 1323 (“[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 13

“Petitioner argues that a person having ordinary skill in the art would have modified McClure’s memory core “such that each sense amplifier 602 is coupled to a pair of global read data lines as taught by Winograd, Merritt, Issa, and Kawasumi.” Pet. 66. The preponderance of the evidence supports this position at least as to Merritt, Issa, and Kawasumi. Petitioner’s declarant, Dr. Chmelar, states that a person of skill in the art would have modified McClure to “reduce power consumption, circuit areas, and/or readaccess time because the plurality of global data bus drivers 606 . . . could be eliminated.” Ex. 1003 ¶ 215. Dr. Chmelar’s testimony on this point is credible and well-supported by the evidence. As explained above, Merritt, Issa, and Kawasumi all teach local amplifiers coupled to global read data lines, and a person of skill in the art would have recognized the advantages of the global read data line configuration by studying those references. Petitioner’s position is further supported by the ’429 patent which admits that a structure of local amplifiers connected to global read data lines was known prior art. In particular, Figure 1 of the ’429 patent illustrates “conventional solution” prior art having local amplifiers 22, 24, and 26 connected to global read data lines 38 and 40. Ex. 1001, Fig. 1, 1:26–48 (“The local amplifiers 22, 24, 26 then drive the gdrd (global read data) lines 38, 40.”); see also Pet 8–9 (mapping claim elements to Figure 1). Patent Owner argues that Petitioner does not establish reason to combine the references’ teachings. Resp. 60–62. We disagree for the reasons explained above. The record as a whole, even if the ’429 patent’s disclosure were not considered, supports by a preponderance of the evidence that connecting local amplifiers to global read data lines was a well-known configuration. See supra 27–32. Connecting McClure’s local amplifiers to global read data lines is no more than use of a known method to yield predictable results. KSR Int'l Co. v.

Patent Owner also argues that Kawasumi criticizes its Figure 1 prior art “for its arrangement of having multiple amplifiers connected to global data lines.” Resp. 61–63; see also Ex. 2001 ¶ 176 (Patent Owner’s declarant Dr. Hassoum stating that Kawasumi says the Figure 1 arrangement is problematic). Patent Owner does not, however, persuasively dispute that use of main amplifiers with global read data lines was a known configuration or that implementation of such a configuration would have been within the abilities of a person of ordinary skill in the art. Reply 28–29. Instead, Kawasumi, for example, teaches that its arrangement of local sense amplifiers 1 providing data to the data bus 2 is a workable configuration. Ex. 1010, 1:49–63.

“Petitioner argues that a person having ordinary skill in the art would have modified McClure’s memory core “such that each sense amplifier 602 is coupled to a pair of global read data lines as taught by Winograd, Merritt, Issa, and Kawasumi.” Pet. 66. The preponderance of the evidence supports this position at least as to Merritt, Issa, and Kawasumi. Petitioner’s declarant, Dr. Chmelar, states that a person of skill in the art would have modified McClure to “reduce power consumption, circuit areas, and/or readaccess time because the plurality of global data bus drivers 606 . . . could be eliminated.” Ex. 1003 ¶ 215. Dr. Chmelar’s testimony on this point is credible and well-supported by the evidence. As explained above, Merritt, Issa, and Kawasumi all teach local amplifiers coupled to global read data lines, and a person of skill in the art would have recognized the advantages of the global read data line configuration by studying those references. Petitioner’s position is further supported by the ’429 patent which admits that a structure of local amplifiers connected to global read data lines was known prior art. In particular, Figure 1 of the ’429 patent illustrates “conventional solution” prior art having local amplifiers 22, 24, and 26 connected to global read data lines 38 and 40. Ex. 1001, Fig. 1, 1:26–48 (“The local amplifiers 22, 24, 26 then drive the gdrd (global read data) lines 38, 40.”); see also Pet 8–9 (mapping claim elements to Figure 1). Patent Owner argues that Petitioner does not establish reason to combine the references’ teachings. Resp. 60–62. We disagree for the reasons explained above. The record as a whole, even if the ’429 patent’s disclosure were not considered, supports by a preponderance of the evidence that connecting local amplifiers to global read data lines was a well-known configuration. See supra 27–32. Connecting McClure’s local amplifiers to global read data lines is no more than use of a known method to yield predictable results. KSR Int'l Co. v.
