“29. In my opinion, the POSITA at the time of the alleged invention of the Asserted Patents would have had a (1) a Bachelor’s degree in a pertinent discipline, such as computer science, electric engineering, computer engineering, or a related field and (2) have 2–4 years of experience in working with computing devices and have an understanding of indexed search systems utilized by such computing devices. 30. I am aware that Petitioner has provided its own definition . . . . 31. I believe Petitioner’s definition is not meaningfully different from my definition of a POSITA. My opinions would not change regardless of which definition of POSITA is applied. Ex. 2001 ¶¶ 29–31. In our Decision on Institution, we adopted Mr. Haeberli’s formulation, finding it to be consistent with the evidence then of record, including the asserted prior art and the ’490 patent. Dec. 9. Following a review of the full record, we agree with Mr. Haeberli’s statement that Petitioner’s definition of one of ordinary skill in the art is “not meaningfully different” from Mr. Haeberli’s for the purposes of this proceeding.

“In our Decision on Institution, the only term that we found it necessary to construe was the term “string separator character” in claim 1. We preliminarily construed this term to mean “a single-character string separator.” Dec. 11, 30–31.

“Having reviewed the evidence of record, we find Mr. Haeberli’s testimony to be more persuasive and better supported by the evidence. According to Dr. Terveen, “[r]obust programming languages such as C and C++, together with well-developed operating system and UI frameworks, . . . allowed an ordinary programmer to build a UI that supported incremental searching, as evidenced by the numerous prior art systems that implemented such functionality, including Entourage, Eudora, Emacs, Canon Cat, SwyftWare, and others. Ex. 1100 ¶ 43 (citing Ex. 1004, 8–9, 161; Ex. 1021, 125, 127, 129; Ex. 1039, 102–103; Ex. 1043, 385–389). The relevant question, though, is not whether it would have been possible to build a user interface that supported incremental search, but whether it would have been “simple and straightforward” to execute an incremental search of multiple partial search strings on large, indexed multi-file databases such as those described in the Lotus Notes references, as Dr. Terveen alleges. None of the prior art discussed in the “State of the Art” section of Dr. Terveen’s initial declaration, taken individually or together, discloses incrementally searching a plurality of files using two partial search strings. See Ex. 1003 ¶¶ 32–33, 37, 40; Ex. 2001 ¶ 100. Thus, creating a user interface might be “simple,” but the evidence suggests that the back-end execution of an incremental search is not. See, e.g., Ex. 1021, 126 (Raskin, concluding that “almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches”).” slip op. at 23
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“different approach from that taken in Lotus Notes. The difference between Raskin’s sequential scanning method and the index-based system described in Wilcox is that sequential scanning by definition can only scan one document at a time as each document is loaded into a “buffer.” See, e.g., Ex. 2020 ¶ 35. Lotus Notes, however, only needs to load the index into memory for a user to be able to locate the single index entry identifying all instances of an indexed term across all indexed files. In fact, Raskin acknowledges that indexing may be necessary to maintain an acceptable response time. Ex. 1021, 132 n.10; see also id. at 129 (indexing speeds search times). Mr. Haeberli’s third and final reason for concluding that one of ordinary skill would not have been motivated to combine Raskin’s incremental search with Lotus Notes is that at the time using incremental searches would have presented “extreme technical difficulties.” Ex. 2001 ¶ 101. Here again we find Mr. Haeberli’s explanation more persuasive than Dr. Terveen’s opinion that combining the teachings from Raskin with Lotus Notes’ teachings “would have required only simple and straightforward software modifications.” Ex. 1003 ¶ 80. According to Mr. Haeberli, “there are serious technical challenges with implementing the complex search strategies of the challenged claims in the systems on which Dr. Terveen relies.” Id. ¶ 96. As Patent Owner argues: searching across a set of files to find specific files requires the system to identify which files are in the set, access those files (which are often not loaded in active memory), search their contents, determine which files contain matches to search criteria, and then present results to the user; all tasks that do not exist in the same way (or at all) for a search confined to text in a single open file already loaded into memory. Sur-Reply 9; see Ex. 2020 ¶¶ 15, 35–36. There would have been other challenges as well. For example, “[t]he type of sequential scanning typically employed to search a single open document is very time and resource intensive if employed to search a large set of documents.” Ex. 2020 ¶ 15. Also, “[i]mplementing incremental search in the Lotus Notes indexed system would necessarily require a larger index, which would slow down, rather than increase the search speed.” PO Resp. 23; see Ex. 2020 ¶ 33. Finally, Raskin itself concludes that “even if incremental searching is advantageous, ‘almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches.’” Ex. 2001 ¶ 96 (emphasis added by Mr. Haeberli) (quoting Ex. 1021, 126). In short, Mr. Haeberli presents three significant reasons why there would have been no motivation or expectation of success in combining the teachings of Wilcox with those of Raskin. Dr. Terveen’s opinion to the contrary, on the other hand, is not supported by evidence. Dr. Terveen testifies that “[a] POSITA would have been motivated to perform Lotus Notes’ multi-string search incrementally for the reasons stated by Raskin: speed, effectiveness, and ease of use.” Ex. 1003 ¶ 78 (citing Ex. 1021 ¶¶ 125–127). The evidence, however, not only fails to support Dr. Terveen’s testimony, but also demonstrates that one attempting to make the proposed combination would not have reasonably expected the proposed combination to result in greater speed or effectiveness.” slip op. at 27

- 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

“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

Petitioner asserts that Kouzani touts the benefits of fractal models and that it would have been obvious to use Kouzani’s fractal model as the object model in Zhou. Pet 44 (asserting that “[a] person of ordinary skill would have therefore been motivated to implement Kouzani’s techniques in Zhao’s system”); see also id. 42–45. (entire argument). Patent Owner argues that Kouzani’s fractals would not result in the claimed limitation. Prelim. Resp. 21–23. In particular, Patent Owner points out that Kouzani’s fractals use a block-based fractal system, which do not include “a representation of the object based on landmarks associated with the object” as required by claim 1. Id. at 21–22. Patent Owner’s argument is persuasive. Even if Kouzani teaches fractals, claim 1 is not broadly claiming any fractal, but rather one that is “based on landmarks” (e.g., eyes, nose, etc.). See Ex. 1001, 13:53–57. The block-based system of Kouzani is based on abstract, repeated patterns of pixels, without regard to what the pixels represent. See, e.g., Ex. 1006, 8 (describing a “search . . . through the domain pool to find a domain block whose contractive transformation best approximates the range block” and then storing all of the transformations that, together, “represent the compressed image of a person’s face”), Fig. 4 (showing example blocks). This is in contrast to looking for particular landmarks in the image. Thus, we find that Petitioner has not sufficiently established that Kouzani’s fractal is based on landmarks. In Petitioner’s ground, Petitioner asserts that Zhao already teaches the claimed landmarks (Pet. 39, citing Ex. 1003 ¶¶ 58, 65), but Petitioner’s ground replaces or modifies the object model of Zhao with the fractals of Kouzani, which are not based on landmarks. Petitioner does not explain how Zhao’s modified model, now using a block-based fractal system, would still have the landmarks of Zhao’s original model. Even if it were obvious to include fractals, we are persuaded that the fractals included by Kouzani are not based on landmarks. Alternatively, if Petitioner is asserting merely to use fractals in Zhao’s models, then Petitioner has not sufficiently accounted for the particular fractals claimed and explained persuasively how merely using fractals in Zhao would lead to the claimed subject matter, i.e., fractals based on landmarks. In either event, Petitioner has not sufficiently established that the proposed combination satisfies the “fractal includes a representation of the object based on landmarks” limitation of claim 1.” slip op. at 11

Petitioner asserts that a person of ordinary skill also would have been motivated to further combine these references with Landry. Pet. 33–35. Dr. Brogioli testifies that “Landry discloses a fault-tolerant boot process that dynamically designates a functional CPU as logical CPU0 that performs the unique functions of a boot processor.” Brogioli Decl. ¶ 147. He testifies further that “[a person of ordinary skill] would have understood Landry’s process would have been a suitable option for selecting a boot processor in Fox’s system consistent with the initialization protocol of the IA-32 multiprocessor system.” Id. He asserts that “[a person of ordinary skill] would have understood the benefits of implementing Landry’s boot processor selection process in Fox.” Id. ¶ 148.

“We are not inclined to adopt Patent Owner’s proposal to require a specific number of years (or a fully bounded range) in the definition of the level of ordinary skill in the art. First, Patent Owner has not offered any legal authority supporting or explaining its position. Second, using the term “at least [X] years” is common practice and generally understood to be an approximation regarding the minimum level of skill of a hypothetical person—in other words, no precision can truly be expected of the specific number of years in this context. In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (“The person of ordinary skill in the art is a hypothetical person.”). The point of the exercise is to provide context for a holistic obviousness analysis. See id. (setting out “various factors” used to analyze the level of ordinary skill); Ryko Mfg. Co. v. Nu-Star, Inc., 950 F.2d 714, 718 (Fed. Cir. 1991) (“The importance of resolving the level of ordinary skill in the art lies in the necessity of maintaining objectivity in the obviousness inquiry.”); Kimberly-Clark Corp. v. Johnson & Johnson, 745 F.2d 1437, 1453 (Fed. Cir. 1984) (the hypothetical person is an “an imaginary being possessing ‘ordinary skill in the art’ created by Congress to provide a standard of patentability”). We are not persuaded of a need for strict precision in the number of years of experience of a hypothetical person used in our analysis in this case. Third, Patent Owner asks for no particular relief based upon its argument. That is, even if we agreed to remove “at least,” Patent Owner does not argue that the outcome of the Decision would be any different.1 1 For example, setting the level of skill to exactly two years of experience would not serve to automatically disqualify an expert having ten years. Kyocera Senco Ind’l Tools v. Int’l Trade Com’n, 22 F.4th 1369, 1377 (Fed. Cir. 2022) (requiring that “a witness must at least have ordinary skill in the art” and stating that “it would be improper to require an expert witness to possess ordinary skill in the art and nothing more”). In conclusion, we apply Petitioner’s proposed level of ordinary skill because it is reasonably consistent with the level of skill implied in the disclosure of the ’588 patent and the cited prior art.” slip op. at 8

“The description of “mapping” in the ’588 patent makes clear to us that it is an association of an input value from a set of input values to a corresponding output value from a set of output values. Id. at 2:44–46 (describing “the mapping table that associates non-core domain operating frequencies and corresponding interconnect operating frequencies”) (emphases added). The “association” described here in the ’588 patent is not merely describing the fact that both exist, but that knowing the value of the first causes you to know the value of the second. This is also how it is described in the claims, wherein the “mapping” is “of selectable frequencies of the graphics processing circuitry to selectable frequencies of the interconnect.” Id. at 8:63–65 (emphasis added). Or more generally, the claim recites a mapping of a frequency to a frequency. In sum, although we agree with the parties that “mapping” should be given its plain and ordinary meaning in light of the specification, we note that the parties appear to dispute whether the prior art teaches the claimed “mapping” based on differing understandings of the plain and ordinary meaning. Based on our analysis above, we determine that a person of ordinary skill in the art reviewing the ’588 patent would understand that the “mapping” limitation requires (1) frequencies mapped to frequencies and (2) that a mapping is an association of one value to a corresponding value such that knowing the graphics frequency means that you know the corresponding interconnect frequency. Further, given that the corresponding frequencies are “selectable,” we understand that to mean that there is a set of possible frequencies that are defined from which to select. Ex. 2001, 21:19–22:2. With this understanding, we can turn to the dispute over whether the prior art teaches the limitations set forth in claims 5 and 12, as no other terms require construction at this time. Realtime, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms. . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).” slip op. at 12

“Given this disclosure, we agree with the testimony of Patent Owner’s expert that Shakkarwar’s empirical calculation, by looking up the frequencies of various devices and summing them up, is not the claimed mapping of frequencies to frequencies. Ex. 2002 ¶ 44 (citing Ex. 1006, 6:8– 16, 6:49–7:17). That is, rather than teaching the use of the graphics device frequency get a corresponding interconnect frequency, Shakkarwar calculates the interconnect frequency by adding up the frequencies of all of the devices using the interconnect. Ex. 1006, 6:63–7:30; Ex. 2002 ¶ 44 (“Considerations of the hardware are addressed through empirical calculation, by knowing the requested data bandwidth of each device.”). Based on the above, we find that Shakkarwar’s table does not map a set of frequencies to a set of frequencies, and we find that the alleged mapping in Shakkarwar is not what is required by the claim because knowing the non-core device frequency in Shakkarwar is insufficient to know the required interconnect frequency. Thus, we credit the testimony of Patent Owner’s expert that Shakkarwar does not teach the claimed mapping. Ex. 2002 ¶¶ 42–45. On the other hand, the testimony of Petitioner’s expert is conclusory on this point, and fails to grapple with these differences between the claims and prior art. Ex. 1003 ¶ 140. Thus, we credit the testimony of Patent Owner’s expert over Petitioner’s expert as to the teachings of Shakkarwar.” slip op. at 16

“that Petitioner has not shown sufficiently that Shakkarwar teaches the claimed mapping limitation, for the following reasons. The lookup table in Shakkarwar has a list of clock speeds (frequencies) for specific devices. Ex. 1006, 7:7–10. These clock speeds represent the bandwidth needs of each individual device. Id. at 7:10–13. By looking up the bandwidth needs of each individual device in use, the system can determine the total bandwidth need. Id. at 7:5–17. For example, if one device requires 20 Megabits of data and the second device requires 10 Megabits of data, then the data rate (bandwidth) required will be 30 Megabits of data. Id. at 7:13–17. If the required bandwidth is different from the current bandwidth, then the current bandwidth must be modified. Id. at 7:18–26. Given this disclosure, we agree with the testimony of Patent Owner’s expert that Shakkarwar’s empirical calculation, by looking up the frequencies of various devices and summing them up, is not the claimed mapping of frequencies to frequencies. Ex. 2002 ¶ 44 (citing Ex. 1006, 6:8– 16, 6:49–7:17).
