      “Petitioner argues that a person of ordinary skill in the art in the relevant field “would have a bachelor’s degree in engineering or computer science, or equivalent field, and two years of experience working on image or video processing, or digital cameras,” or alternatively “would have four years of experience working on image or video processing, or digital cameras.” Pet. 6. Petitioner further argues that an “advanced graduate degree” may “make up for the work experience.” Id. (citing Ex. 1002 ¶¶ 33–34). “Patent Owner applies Petitioner’s proposed level of skill.” PO Resp. 4–5 (citing Ex. 2027 ¶¶ 19–20).

      “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

      “Patent Owner’s arguments do not persuasively undermine Petitioner’s position. Sakamoto expressly discloses setting the ratio of negative to positive electrode active material in the range of 1.05 to 1.30. Ex. 1005 ¶ 8.

Id. ¶ 8 (providing a secondary battery with a capacity ratio between 1.05 and 1.30 and noting that by setting the ratio within this range the resulting secondary lithium battery is “safe due to low risk of heat being generated and an explosion occurring”). We also disagree that Sakamoto teaches away from elevated voltages or from increasing the amount of lithium in circulation. See PO Resp. 29. Contrary to Patent Owner’s arguments, Sakamoto provides no general teaching against using a charge cut-off voltage above 4.2 V, or against increasing the level of lithium in circulation. Nor does Sakamoto “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). Rather, Sakamoto warns against setting the reversible capacities of the positive and negative electrode substantially equal as this may result in excess lithium plating on the surface of the electrode.

      “Patent Owner’s argument is unpersuasive because the Krames declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 21 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52. One requirement of this apparatus is that it comprise “at least one semiconductor chip” (id. at 10:1) where the “at least one semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts.” Id. at EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction of “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as meaning “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 54 (quoting Ex. 1008, 10). Notably, claim 21 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim.

      “We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’961 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 19. The prior art of record, for example, Begemann, likewise reflects “a hybrid of the light bulb art and semiconductor art.” Id. (quoting Pet. 28). Petitioner’s expert, Dr. Lebby, agreed that a person having ordinary skill in the art would need to be “familiar with thermal issues.” Ex. 2015, 26:15– 28:16. While Petitioner’s proposed description of a person having ordinary skill in the art could, in some instances, be sufficient to qualify a person as having ordinary skill, Patent Owner’s proposal is a more complete and accurate description of the level of skill commensurate with the scope of the challenged ’961 patent claims. Patent Owner’s description appears consistent with the prior art and patent specification before us and is supported by witness testimony. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “A. Person of Ordinary Skill in the Art Petitioner argues that a person of ordinary skill in the art would have been a technical person having “a Bachelor’s degree in electrical engineering, computer engineering, applied physics, or a related field, and approximately two years of experience working in the design, development, and/or testing of memory circuits, related hardware design, or the equivalent, with additional education substituting for experience and vice versa.” Pet. 11. For purposes of this inter partes review, Patent Owner adopts Petitioner’s definition. Resp. 13. Based on the totality of the record including the ’429 patent specification, cited references, and expert testimony, we find that Petitioner’s definition for a person of skill in the art is appropriate.” slip op. at 8

      “amplifiers “by the strobe reset generator instead [of] by the strobe global word line (gwlstrobe) 52”). 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

    • Expert testimonyPetitioner expert creditedDecided for petitioner

      “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. Teleflex Inc., 550 U.S. 398, 401 (2007). 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.

      “We agree with Petitioner. Although Figures 4 and 5 of the ’960 patent show keys that are partially surrounded by shadowing or shading, there is no suggestion in the Specification that the “blended shadow” recited in the claims should be limited to only this shadowing. The claim language itself, referring to a blended shadow of the representation of at least one key and the main image (see claim 24), indicates explicitly that the blended shadow incorporates both the key image and the main image and, thus, should not be limited to the shadowing surrounding the keys. Accordingly, based on the full record, we adopt Petitioner’s proposed construction of “blended shadow” as “a portion of a composite image in which the main image is visible through the overlaid image as a result of combining the data from corresponding pixels from the main and overlaid images” for the purpose of this Final Written Decision.

      “We agree with Patent Owner. Petitioner does not explain adequately where the detailed analysis set forth in the Reply is made in the Petition, and, in any event, we do not find the arguments persuasive. “A patent claim is anticipated if a single prior art reference expressly or inherently discloses every limitation of the claim.” DDR Holdings, LLC v. Hotels.com, L.P., 773 F.3d 1245, 1252 (Fed. Cir. 2014). Here, Petitioner does not describe sufficiently how Gough expressly discloses using logical operators to accomplish the blending process.6 We do not agree that either Gough’s description of the blending process depicted in Figures 10a–10f (Ex. 1007, 10:23–41) or Gough’s description of using the color look-up table (id. at 14:9–19) expressly discloses using logical operators, and such express disclosure is required for anticipation. At best, Petitioner’s arguments suggest how Gough could be envisioned as using logical operators, but do not explain adequately where or how Gough expressly discloses using logical operators to carry out the blending process. For these reasons, we are not persuaded that Petitioner has shown, by a preponderance of the evidence, that independent claim 1, and claims 2, 3, 5, 7–10, and 12–14 depending therefrom, are anticipated by Gough.” slip op. at 15

See id. at 48 (“[t]o the extent that these features may not be fully disclosed in Buxton, they are clearly disclosed in Harrison”). For purposes of this Final Written Decision, we determine the teachings of Harrison are cumulative to the teachings of Buxton, and therefore, do not address Harrison further.7 4. Claims 1–3, 5, 7–10, and 12–14 Petitioner argues that “Buxton discloses nearly all of the elements and limitations” of the challenged claims. Pet. 42. With respect to claim 1, Petitioner argues that Buxton discloses using alpha blending in accordance with the equation I = αI1 + (1-α)I2, where I is the resulting color intensity, I1 is the color intensity of the foreground image pixel, I2 is the color intensity of the background image pixel, and α is the specified transparency level between 0 and 1. Id. at 43–44 (citing Ex. 1009, 17:17–28). Petitioner argues that Buxton’s alpha blending “permits pixels to be ‘dedicated simultaneously’ to both images in order to produce a composite image” and is an “example of an operation using logical operators to provide different blending effects.” Id. at 44 (citing Ex. 1009, 16:63–17:4). Petitioner contends that although “Buxton may lack explicit disclosure of . . . a touchactivated device (required in claims 1 and 26),” Bier discloses that a touch screen is interchangeable with a mouse. Id. at 44–45. Petitioner also contends that Bier discloses a keyboard superimposed over a display.

      “After considering all evidence and arguments, we agree with Patent Owner. In particular, we determine that Petitioner’s arguments do not persuade us that Buxton’s alpha blending equation uses operators that manipulate binary values at the bit level, consistent with our construction of “logical operators.” The alpha blending equation unquestionably involves arithmetic operations, which we find differ from logical operations. Furthermore, Petitioner has not shown persuasively whether any logical operations overlap with any arithmetic operations. Therefore, we agree with Patent Owner’s contention that Buxton’s alpha blending equation does not use logical operators.” slip op. at 24

      “To remove Boehm as a prior art reference, the record must establish either: (1) a conception and reduction to practice before the filing date of Boehm; or (2) a conception before the filing date of the Boehm patent combined with diligence and reduction to practice after that date. See Taurus IP, LLC v. DaimlerChrysler Corp., 726 F.3d 1306, 1323 (Fed. Cir. 2013). Under either approach, however, it must be proven that conception occurred prior to November 4, 2002. See id. “Conception exists when a definite and permanent idea of an operative invention, including every feature of the subject matter sought to be patented, is known.” Sewall v. Walters, 21 F.3d 411, 415 (Fed. Cir. 1994). Furthermore, “[t]he conception analysis necessarily turns on the inventor’s ability to describe his invention with particularity. Until he can do so, he cannot prove possession of the complete mental picture of the invention.” Burroughs Wellcome Co. v. Barr Labs., Inc., 40 F.3d 1223, 1228 (Fed. Cir. 1994).

      “We agree with Patent Owner that Petitioner’s proposed construction does not take into account properly the “managing the data path” claim language, even given that Petitioner construes only the limitation “a Local Area Network (LAN) routing system” rather than the entire phrase. In any event, we decline to adopt Petitioner’s proposed construction because it erroneously equates a LAN routing system to “a local area network or equivalent circuitry.” We do not view a LAN routing system as being equivalent to a LAN itself or circuitry “equivalent” to a LAN, which Petitioner has not described. We also decline to adopt Patent Owner’s proposed construction, which is not supported adequately. Specifically, Patent Owner does not explain sufficiently why managing the data path necessarily is accomplished “by controlling client devices’ access to the Internet and by controlling access to the client devices from the Internet.” Patent Owner asserts that the Specification of the ’771 patent describes managing the data path “by controlling the client devices’ access to the Internet, such as by requiring authentication before permitting access” and preventing “unauthorized access in the opposite direction by ‘allow[ing] all client devices 30 to share a single external Internet address.’” PO Resp. 5–6 (citing Ex. 1001, 4:1–14); see also Tr. 43:10–14 (stating the Specification “talks about managing as controlling the client devices’ access to the Internet, things like authentication, and controlling access to client devices from the Internet, like sharing a single Internet address”). The Specification, however, does not describe “managing the data path” explicitly, and we are not persuaded that the “managing the data path” claim language necessarily includes the authentication and sharing functions described in the cited passages. As such, Patent Owner’s reliance on the cited passages in its construction seeks to improperly read limitations from the Specification into the claim. See In re Am. Acad. of Sci. Tech. Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). Dr. Tewfik testifies that “[i]n computer networking, routing systems allow data to be exchanged between networks by forwarding data to a recipient device in one network from a sending device in another network.” Ex. 2004 ¶ 10. Dr. Tewfik further testifies that, “[i]n the ’771 patent, the LAN routing system is the LAN [R]outer 16,” and the LAN routing system allows data to be exchanged between the short-range local network and the Internet. Id. ¶ 11. This testimony is not dissimilar to Dr. Roy’s testimony that a LAN routing system “routes (i.e. communicates) data between a client device that is accessible via a short-range wireless interface and the Internet that is accessible [via] a long range Internet access interface.” Ex. 1012 ¶ 18. Thus, Dr. Tewfik and Dr. Roy essentially are in agreement that a routing system directs (i.e., exchanges, routes, or communicates) data between networks. This meaning is consistent with the Specification of the ’771 patent, which describes LAN Router 16 as “direct[ing] traffic from the access point 12 to the Internet 20 via the fixed WAN interface 18.” Ex. 1001, 3:33–34. Therefore, applying the broadest reasonable interpretation of the claims in light of the Specification, we interpret the phrase “a Local Area Network (LAN) routing system managing the data path between said wireless access point and said Internet access interface” to mean “a system that directs data between a local area network and the Internet by managing the data path between a wireless access point and an Internet access interface.”” slip op. at 8
