    “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012). The Technical Data Sheets may support a finding that the Xirallic® products they describe existed as of the dates on the documents, but they do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.” slip op. at 20

Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

    “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

    “information, is not sufficient evidence to establish that Mori discloses the “volume concentration” recited in claim 1. Patent Owner does not dispute that there is some magnetic alloy present “in the magnetic layer” of Mori. The relevant question, however, is how much and how Mori’s disclosed values were determined. Unlike the term “volume concentration,” for which the parties offered undisputed evidence regarding accepted meanings of the term in the art (i.e., packing fraction and pigment volume concentration), we have not been directed to similar evidence regarding the phrase “fill rate”/“filling rate” in Mori. Thus, although Mori states “[t]he filling rate by volume of the strongly magnetic alloy powder in the magnetic layer can be equal to or higher than 30%” (Ex. 1003 ¶ 11 (emphasis added)), Petitioner has not offered sufficient evidence demonstrating that the term “filling rate” in Mori refers to a final product-based value. As a result, we find that this language in Mori does not establish, by a preponderance of evidence, that Mori discloses the “volume concentration” recited in claim 1.” slip op. at 21

    “Based on our analysis of the intrinsic and extrinsic evidence, we agree with Patent Owner that a person of ordinary skill in the art would understand the ’507 patent to speak in terms of effects, not molecules. See PO Resp. 4– 5; Tr. 41:8–16. We, therefore, construe the recitation “distilling [a mixture comprising water, acetic acid, methyl iodide, methyl acetate, methanol, and at least one PRC] to separate the mixture into a plurality of streams, at least one of said streams being a PRC enriched overhead stream comprising dimethyl ether” in step (a) of claim 42 as requiring the presence of dimethyl ether in the PRC enriched overhead stream in an amount that one of ordinary skill in the art would recognize as being more than trace or insubstantial. Such amount would be, for example, more than the amount produced in a conventional, prior art, low water carbonylation process that used the same initial reactor contents and conditions, and the same processing equipment. We further interpret this language as requiring the presence of DME in the PRC enriched overhead stream in an amount sufficient to cause (1) a reduction in the solubility of methyl iodide in water during the extraction of the PRC enriched overhead stream (claim 42, step (b)) and (2) an increase in the amount of methyl iodide recoverable during a subsequent extraction of the raffinate stream, which increase in recoverable methyl iodide would be recognized as more than insubstantial by the ordinary artisan.” slip op. at 42

See Ex. 1046, 281:14–22; Ex. 2029 ¶ 112. Dr. Porcelli testified that Mr. Jones’s estimates of DME content in the ’095 patent Example were based on numerous assumptions that rendered his estimations of reactor and distillation overhead DME concentrations meaningless. See Ex. 2029 ¶¶ 137, 140, 151.

Mr. Miura’s measured amount of DME present in the first overhead in Experiment 1 was less than half the amount Mr. Jones calculated would be present, supporting Dr. Porcelli’s testimony that the loss of DME via the vents would have had a marked impact on the actual amount of DME sent to distillation column 40 (from which the second overhead stream is produced) in the ’095 patent Example.

    “In sum, we determine Petitioner has failed to meet its burden to show, by a preponderance of the evidence, that the ’095 patent describes a process that inherently results in dimethyl ether in a PRC enriched overhead stream (produced by distilling a mixture comprising water, acetic acid, methyl iodide, methyl acetate, methanol, and at least one PRC) in an amount that is (1) more than trace or insubstantial, and (2) sufficient to cause (a) a reduction in the solubility of methyl iodide in water during extraction of the PRC enriched overhead stream and (b) an increase in the amount of methyl iodide recoverable during a subsequent extraction of the raffinate stream, as required by the broadest reasonable interpretation of claim 42. Absent from the record is any evidence that DME is present in the second overhead in the ’095 patent Example in the amount required by independent claim 42 and its dependent claims 43, 44, 47–51, 53, and 55–57. Petitioner’s challenge with respect to claim 57 is based on obviousness over the combination of the ’095 patent and JP ’712. Petitioner relies on JP ’712 for a teaching that “methyl iodide concentration can be controlled by extraction temperature, . . . and that the concentration[] recited in [claim 57 is] well known in the art.” Pet. 55. Petitioner has not explained how JP ’712 cures the deficiency in the ’095 patent’s failure to describe step (a) of claim 42. Accordingly, we likewise determine Petitioner has failed to meet its burden to show unpatentability of claim 57 by a preponderance of the evidence. We conclude Petitioner has failed to meet its burden to show unpatentability of claims 42–44, 47–51, 53, and 55–57 of the ’507 patent.” slip op. at 59

Ex. 2029 ¶¶ 130–131. Mr. Jones conceded “some DME will be carbonylated in the reactor” (Ex. 1060 ¶ 45), and that the carbonylation of DME to make acetic acid under low water conditions is an irreversible reaction (Ex. 2026, 227:19–228:1). See also Ex. 1060 ¶ 27 (arguing Exhibits 2032, 2034 evidence DME formation in a batch reactor during methanol carbonylation, but admitting that as the water and methyl acetate start to diminish, DME concentration begins to drop and DME is eventually carbonylated into either acetic acid or acetic anhydride). Mr. Jones disagreed with Dr. Porcelli’s testimony that “carbonylation of DME is . . . known to have a fast reaction rate” and “would be consumed by carbonylation faster than it would be formed by methanol dehydration, especially under low water conditions” (Ex. 2029 ¶ 130). Ex. 1060 ¶ 44. Mr. Jones provided testimony explaining why he believes “the carbonylation of DME is not particularly fast.” Id.; see id. ¶¶ 45–48. Mr. Jones relied on a textbook by Gauthier-Lafaye (Ex. 1062), published in 1987, as evidence that the carbonylation of DME proceeds more slowly than the carbonylation of methyl acetate. Ex. 1060 ¶ 47. Mr. Jones testified that because the reaction liquid in the ’095 patent Example is reported to contain 1.6 wt% methyl acetate, and the carbonylation rate of DME is even slower than that of methyl acetate, then “it stands to reason that the carbonylation rate of DME is not going to be so fast as to ‘immediately’ react away any DME that is formed via the methanol dehydration equilibrium reaction.” Id. ¶ 48. Mr. Jones further testified that consideration of this competing side reaction was “irrelevant to calculating equilibrium concentration” of DME in the reactor in the ’095 patent Example. Id. ¶ 51. The disclosure in Gauthier-Lafaye relied upon by Mr. Jones relates to the carbonylation of methyl acetate into acetic anhydride (Ex. 1062, 9), i.e., a different reaction system than the ’095 and ’507 patents (see Paper 73, 8 (Observation #F.1)). This evidence, therefore, does not support Mr. Jones’s testimony that the carbonylation of DME in the ’095 patent reaction system was irrelevant to his calculation of equilibrium DME concentration. Rather we credit Dr. Porcelli’s testimony that removal of DME by rapid carbonylation would have had an effect on the presence, or at least the quantity, of DME in the ’095 patent Example, and that this factor should have been taken into consideration by Mr. Jones in his calculations. See Ex. 2029 ¶ 130. Mr. Jones testified that in view of the low boiling point of DME (-23.7 ºC), most of the DME will immediately flash from the reactor product . . . and be concentrated in the overhead streams. In view of the relatively low amount of DME in the reactor and overhead, DME’s very low boiling point, and the elevated temperatures in the reactor, special handling techniques would be needed to sample for such a compound in the reaction mixture. It is therefore not surprising that the presence of DME was not measured in the ’095 patent, despite the fact that it was undoubtedly present. Ex. 1060 ¶ 118. Given Mr. Miura’s testimony that he believed DME, if present, would have been detectable (Ex. 1046, 280:9–281:1), and Paulik’s disclosure that insubstantial amounts of DME were measurable as early as 1970 (see, e.g., Ex. 2037, 13:47–49, 15:32–34), Mr. Jones’s testimony (see, e.g., Ex. 1060 ¶ 101 (“It should be clear to someone skilled in the art that very dilute and trace components are frequently not reported in chemical analytical results or in listed process stream compositions.”)) does not show convincingly that DME was present in the second overhead in more than a trace quantity, if at all. See id. ¶ 90 (“[T]he only issue is whether some amount of DME exists (which clearly it does).”).” slip op. at 56

    “have been present in the distillation overhead in the ’095 patent Example in an amount sufficient to reduce solubility of methyl iodide in water during subsequent water extraction steps. Mr. Miura testified that 1.2 wt% DME was present in the second overhead in Experiment 1. Ex. 1005 ¶ 13, Table 1. Mr. Jones testified that he would expect the amount of DME in the second overhead in the ’095 patent process to be about three times the amount of DME in the overhead in Miura Experiment 1 (Ex. 2040, 289:10–– 298:7), because Mr. Miura’s experiment was carried out under conditions less favorable to DME formation as compared to the conditions in the ’095 patent Example (see Ex. 1060 ¶¶ 130, 139). A preponderance of the evidence, however, does not support a finding that DME was present, if at all, in more than a trace quantity/insubstantial amount in the second overhead of the ’095 patent Example, for the following reasons: Although Mr. Miura reported that the second overhead in his Experiment 1 contained 1.2% DME (Ex. 1005 ¶ 13, Table 1), he did not testify that this quantity would be present in the ’095 patent Example despite acknowledged differences in quantities of reaction components and operating conditions (see id. ¶ 21). Rather, Mr. Miura testified that Experiment 1 provided evidence that DME simply was present in some amount in the second overhead in the ’095 patent Example. Id. (“[T]he deviations would not affect the outcome with respect to the presence of DME in the first and second overheads.”). Mr. Miura testified that he supervised the ’095 patent Example and believed DME was present and accounted for in the 0.9 wt% reported as “others.” Ex. 1046, 241:17–242:9. Therefore, we are not persuaded by Mr. Jones’s testimony that the amount of DME in the second overhead in the ’095 patent process would be about three times the amount of DME in the overhead in Miura Experiment 1, i.e. 3.6 wt% (Ex. 2040, 289:10––298:7). See Tr. 70:3–8 (wherein Patent Owner’s counsel raises this inconsistency). We are not persuaded by Mr. Jones’s testimony that an amount as high as 3.6 wt% DME could have been present in the ’095 patent Example, but not reported (see Ex. 2040, 301:18–303:2; Paper 73, 5–6 (Observation #C.4)), since the prior art, e.g., Paulik, clearly indicates DME was considered an undesirable reaction byproduct in a carbonylation process. Mr. Miura did not testify as to what portion of the 0.9 wt% reported as “others” in the ’095 patent Example constituted DME, or whether the amount of DME would be considered more than a trace quantity/insubstantial amount. Nor is there any testimony or evidence that 0.9 wt% or less DME in the overhead/feed to the extractor would have been an amount sufficient to cause a reduction in the solubility of methyl iodide in water during extraction of the PRC enriched overhead stream and an increase in the amount of methyl iodide recoverable during the subsequent extraction of the first raffinate stream as required under the broadest reasonable interpretation of claim 58 of the ’507 patent. We are not persuaded that Mr. Jones’s calculations provide a reliable method of determining the amount of DME present in a methanol carbonylation process. Mr. Miura and Dr. Porcelli agreed that it is extremely difficult to anticipate the presence or amount of a component such as DME in a methanol carbonylation system such as the one described in the ’095 patent. See Ex. 1046, 281:14–22; Ex. 2029 ¶ 112. Dr. Porcelli testified that Mr. Jones’s estimates of DME content in the ’095 patent Example were based on numerous assumptions that rendered his estimations of reactor and distillation overhead DME concentrations meaningless. See Ex. 2029 ¶¶ 137, 140, 151. Dr. Porcelli testified, for example, that it was “improper and incorrect” for Mr. Jones “to fail to account for DME lost with the vent stream in the reactor, especially because of the high volatility of DME.” Id. ¶ 148. Mr. Miura’s measured amount of DME present in the first overhead in Experiment 1 was less than half the amount Mr. Jones calculated would be present, supporting Dr. Porcelli’s testimony that the loss of DME via the vents would have had a marked impact on the actual amount of DME sent to distillation column 40 (from which the second overhead stream is produced) in the ’095 patent Example. See Ex. 1060 ¶ 153 (“(103 ppm (calc.) vs. 48 ppm (actual)) is likely to due to loss of DME with the vent gas from the splitter condenser, due to the very low boiling point of DME”); see also Ex. 1039 ¶ 97; Ex. 1060 ¶ 121 (wherein Mr. Jones agreed that the loss of DME from the vent stream in the separator (or decanter) after splitter column 14 in the ’095 patent process would be substantial).” slip op. at 55

Patent Owner argues that Conwell teaches identifying a match using a look-up table, but the process is not disclosed to be non-exhaustive. Id. at 24 (citing Ex. 1009, 3:43–44, 5:59–61, Fig. 3; Ex. 2005 ¶¶ 364–366).

    “As Patent Owner points out, the second search of the identified matches is performed exhaustively of Works A, C, D, and E. Tr. 40–43 (citing Ex. 1010 7:4–9; Ex. 2005 ¶ 288; Ex. 2006, 325:12–21, 336:12–22). If viewed as separate and independent searches, both would be exhaustive of the data set being searched, and if viewed as a single search, all of the initially input records of the data set (i.e., Works A–E) would be searched by that single search, making it exhaustive. As such, we agree that Ghias does not teach or suggest a non-exhaustive search, as recited in the independent claims. Petitioner responds that Ghias’s subsequent searches are non- exhaustive (Reply 13–14), but we have addressed the same in the prior paragraph, not finding it to be persuasive. Petitioner also argues that the queries from the “first” and “second” searches need not be the same, and in fact would likely be different, such that the results for the first query could exclude non-matches from the results, where those non-matches would be matches for the second query, so that the subsequent search for the second query would not consider these excluded references. Id. at 14. We are not persuaded, however, as the search would still be exhaustive to the dataset provided to the search algorithm. As discussed above, we construe “non-exhaustive search” as “a search that locates a match without a comparison of all possible matches.” We are not persuaded that simply because a search does not seek matches outside of its input records would make that search non-exhaustive; that would make every search non-exhaustive, because it is, by definition, limited to the records input or available to the search algorithm. Petitioner also argues that Ghias discloses that its string matching algorithms operate faster than a brute force search (Reply 14–15), but we are persuaded, as discussed above, that this disclosure is related to comparing a work with a single record in the database, and not with respect to all of the records in the database. Petitioner also argues that Ghias discloses that performance may be improved by “packing all the songs into one file,” whereby the non-exhaustive searching within a record would apply to all of the concatenated record, making the search of the records non-exhaustive. Id. at 15. With respect to this latter argument, we agree with Patent Owner that this represents a “new theory” of the ground than that established in the Petition. Paper 24, 1–2.

    “We are not persuaded by Petitioner’s argument or evidence. Petitioner’s conclusion does not follow logically and necessarily from Petitioner’s underlying premises. The system configuration described by Petitioner just as easily could be accomplished by sending on/off commands to the various input and output components so that the desired input device is powered on and the non-desired input device is powered off. The same can be said of the output devices. Thus, the entertainment system, as a whole, can be configured by sending power on/off commands to various devices and then passively routing the input and output signals through the VCR. Petitioner cites to no explicit disclosure in Dubil where the VCR actively switches between a plurality of inputs and a plurality outputs. We have reviewed Dubil and find no such explicit disclosure. Neither do we find that Dubil discloses active switching of the VCR inherently. While it may be possible that the VCR could switch between sources and destinations, we are not persuaded that such functionality is necessarily present in Dubil for it to operate. Inherency may not be established by probabilities or possibilities. See Agilent Tech., Inc. v. Affymetrix, Inc., 567 F.3d 1366, 1383 (Fed. Cir. 2009).

We are not persuaded that Dubil discloses a “configuration of the entertainment device” as we have construed the term. Petitioner’s evidence and argument focuses on Dubil’s entertainment system as a whole. However, “configuration of the entertainment device,” as it is used in claim 13, refers to a set of executable instructions and data stored in memory in the entertainment device that is first downloaded from a personal computer and is then accessed and used after the entertainment device receives a signal from the remote control that contains a command value that is associated with such configuration.

    “1. Level of Skill in the Art Petitioner contends that a person of ordinary skill in the art would have had at least a B.S. degree in Electrical Engineering, Computer Engineering, or the like, and at least three years of additional academic or industry experience. Pet. 11 (citing Ex. 1003 (Stark Decl.) ¶ 45). Dr. Wells “generally agree[s] with Dr. Stark in paragraph 45 of his declaration.” Ex. 2007 ¶ 20. We adopt the parties agreed statement of the level of skill of a person of ordinary skill in the art.” slip op. at 21

    “Dr. Stark’s testimony also is not supported by the description in the ’480 patent. In one example, Dr. Stark testifies that: For the case of the receiver side (dehopping) as shown is Fig. 3, the same logical channel would “hop” onto different RF channels each successive GSM TDMA frame. This would mean that for a particular TDMA frame, a given logical channel, e.g., channel 1 on slot 1, would be at a particular RF channel such as indicated by location “27” in the table in Fig. 3. But in the next TDMA frame, the same logical channel, would be placed onto a different RF channel, e.g., location “2” in the table in Fig. 3. By the controller supplying a new mapping signal (table) every TDMA frame, the samples from the correct RF channel for the associated logical channel could be placed onto the TDM bus for processing by the corresponding DSP 18. Ex. 1022 ¶ 17. This is inconsistent with the description in the ’480 patent. Locations “27” and “2” in DP RAM Enable 202 merely indicate whether data can be asserted into time slots 27 and 2. Ex. 1006, 9:46–10:3. Changing the mapping in DP RAM Enable 202 to enable slot “2” and disable slot “27,” without additional changes elsewhere in the system, would not result in different RF channels being switched to the same logical channel. In this example, and the others cited above, Dr. Stark repeatedly testifies that simply re-programming DP RAM Enable 202 will change the mapping of physical RF channels and logical channels. Nevertheless, as Patent Owner argues (PO Resp. 26–27), the ’480 patent does not support that testimony. Because Dr. Stark’s testimony is inconsistent with the description in the ’480 patent, we give his testimony little weight.5” slip op. at 28

    “(Ex. 1006, 5:4–17) describes a basestation’s exchange of RF signals with mobile subscriber terminals. Specifically, the passage is directed to the modulation of voice and data channels over RF carrier signals: “The RF carrier signals are modulated with voice and/or data (channel) signals which are to be coupled to the public switched telephone network (PSTN) by the basestation 10.” Ex. 1006, 5:6–9 (emphasis added). In that context, the ’480 patent explains that “[t]he particular modulation in use[] may be any one of a number of different wireless (air interface) standards such as the well known Advanced Mobile Phone Service (AMPS), time division multiple access (TDMA) such as IS-54B, code division multiple access (CDMA) such as IS-95, frequency hopping standards such as the European Groupe Speciale Mobile (GSM).” Id. at 5:9–17 (emphases added). We find that this passage states, at most, that the system described in the ’480 patent supports the modulation specified by the GSM standard. Petitioner admitted at the hearing that frequency hopping is not a modulation scheme and that GSM specifies the same modulation scheme whether or not frequency hopping is used. Tr. 62:17–63:23. The passage of column 5, lines 9–17, of the ’480 patent is consistent with the system of the ’480 patent being programmed to support the modulation scheme of GSM, without supporting the optional frequency hopping functionality. While GSM is referred to as a “frequency hopping standard[],” the frequency hopping functionality is inapposite to the modulation being discussed in the passage. Tr. 63:17–22 (“JUDGE McKONE: And you can use the same modulation regardless of whether you are using frequency hopping or not, is that right? MR. SPEARS: Exactly. Yeah, it’s the same slot. It’s the same framing. It’s the same TDMA frames. It is all the same.”). We find that the ’480 patent does not state, explicitly or implicitly, that the described system implements the optional frequency hopping functionality of GSM. We recognize that Dr. Stark testifies that “a [person of ordinary skill in the art] would have understood that explicit reference to GSM to include reference to the constituent part of the GSM standard that specifies frequency hopping, i.e., GSM 05.02, and thus a [person of ordinary skill in the art] would understand that the ʼ480 Patent discloses this limitation as described below.” Ex. 1003 ¶ 90. Dr. Stark’s testimony, however, relies on his assumption that frequency hopping is a type of modulation. Id. As noted above, Petitioner has conceded that frequency hopping is not a type of modulation. Accordingly, we do not credit Dr. Stark’s testimony on this point. At the hearing, Petitioner argued that “there is no reason to say you are doing frequency hopping unless you are frequency hopping.” Tr. 63:22– 23. We are not persuaded. The ’480 patent does not state that its system is “doing frequency hopping.” Rather, it characterizes GSM as a “frequency hopping standard[].” While this characterization may be relevant to obviousness (discussed below), it is not a statement explicitly showing that the system of the ’480 patent implements frequency hopping.” slip op. at 17
