      “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

      “witnesses. See Elbit Systems of Am., LLC v. Thales Visionix, Inc., 881 F.3d 1354, 1358 (Fed. Cir. 2018) (citing Trs. of Columbia Univ. v. Illumina, Inc., 620 F. App’x 916, 922 (Fed. 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

      “In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

      “II. STANDARD OF REVIEW When rehearing a decision on institution, we do not review the merits of the decision de novo, but instead review the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may be determined “if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors.” Arnold Partnership v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004) (citing In re 1 US 2013/0108922 A1, published May 2, 2013 (Ex. 1004, “Shinozaki”). 2 G.

      “For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

      “Petitioner, however, does not adequately explain why a POSITA would have been motivated to modify Kim’s copper foil surface to have a Pc value of 19.2 as reported in Griesi. In particular, neither Petitioner nor Dr. Randall points us to, nor do we discern, any teaching in Griesi that a peak count of 19.2 provides any particular benefits or properties that would have lead a POSITA to modify Kim’s copper foil surface as Petitioner proposes. Instead, Petitioner’s arguments that a POSITA would have been motivated to modify Kim’s copper foil surface with Griesi’s peak count patent itself. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 421 (2007) (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”).

Yet Petitioner does not specify how such a webserver would be integrated with the other elements from Ellis and Spivey cited by Petitioner. At best, Petitioner provides a background section on the known use of webservers (see id. at 11 (citing Ex. 1001 ¶¶ 49–53, 127–134)), but this does not provide a rationale for integrating a webserver in the Ellis–Spivey combination. We also have considered Petitioner’s cited testimony from Dr. Wicker supporting this background section. The first cited portion, which is located at paragraphs 49–53 of Dr. Wicker’s declaration, supports the premises in the background section, but does not include a rationale for adding a webserver to the Ellis– Spivey combination. See Ex. 1001 ¶¶ 49–53.

      “c. Analysis We are not persuaded by Petitioner’s rationale for adding a facilitator- type webserver to the Ellis–Spivey combination based on “POSA’s Knowledge.” First, Petitioner’s combination of Spivey with Ellis is already allegedly based on improving latency issues via the incorporation of Spivey’s LDSD and MQSD in Ellis’s system. See Pet. 22–24. Petitioner touts that this modification would result in reduced latency to a time period “at least two orders of magnitude shorter than conventional time periods of legacy devices.” Id. at 23 (citing Ex. 1017 ¶ 96). But the Petition does not establish whether this latency improvement would or could be maintained when adding a separate webserver, as it has proposed. And Dr. Rubin testifies that the inclusion of an additional webserver—an additional component—is likely to create latency insofar as it must receive, process, and/or handle data. Ex. 2001 ¶ 305. We are persuaded by Dr. Rubin’s testimony, and we find that adding a webserver to Petitioner’s existing Ellis– Spivey combination tends to undermine Petitioner’s foundational rationale for combining these references, which is the reduction of latency.

Dr. Wicker’s supporting testimony stresses that “webservers were well-known components in streaming systems that were useful for facilitating communication between client devices and socket servers, and client devices and media sources.” Ex. 1001 ¶¶ 128–132.

On the present record, we are satisfied that this definition of the level of skill is consistent with the teachings of the ’088 patent and the asserted prior art. Notwithstanding, we would reach the same determination under Petitioner’s formulation of the level of skill.” slip op. at 11

      “Petitioner contends that all claim terms should be given their plain and ordinary meaning. Pet. 8. Petitioner also argues that an ordinarily skilled artisan would have known that a “socket” is “a uniquely addressable communication endpoint on a server where first event information is provided to a VCD [viewer client device].” Id. at 34 (citing Ex. 1001 ¶ 163). Thus, Petitioner argues that a “first event socket corresponding to the first event information” is “a socket where information about one sporting event is provided to VCDs.” Id. Patent Owner states that “[e]xcept for the ‘socket’ term for which Patent Owner applies Petitioner’s construction . . . for purposes of [its] preliminary response, Patent Owner agrees that no terms require construction and construes all other terms consistent with their plain and ordinary meaning.” Prelim. Resp. 20–21. For purposes of this Decision, we determine that no aspects of the challenged claims require explicit construction. See, e.g., Realtime Data, 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.

      “We disagree with Patent Owner on this record. The language of claim 1 recites “location access rights of said device from said first wireless device.” The claim language does not limit the location access rights to be of only the one other device, at the exclusion of other devices. The ordinary and customary meaning of “location access rights of said device from said first wireless device” encompasses rights that allow other devices, in addition to the recited device, to access location information. The disclosure in the written description is consistent with the ordinary and customary meaning. Although the written description states that an object of the invention is to provide a security feature which allows a user to limit or deny access to a particular user, the written description discusses other purposes served by the assignment of access rights. For example, the written description discloses that “[u]sers may be added, individually or in groups, to a list of users with location access rights to a specific user by that specific user. A specific user may, at any time, modify, delete, or add users allowed to access his or her location.” Ex. 1001, 3:22- 26. The written description further discloses that “a user may organize his/her user list into groups and assign access rights to that group (e.g., family member user group, close friend user group).” Id. at 13:9–12. The fact that the written description of the ’039 patent sets forth multiple objectives to be served by the access rights confirms that these terms should not be construed as limited to a single device. Phillips, 415 F.3d at 1327. Further, because the written description here includes an embodiment where a user assigns access rights to a group, we are persuaded that the scope of the disputed claim terms encompasses a group permission. Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1583 (Fed. Cir. 1996) (holding that interpreting a claim to exclude an embodiment disclosed in the written description “is rarely, if ever, correct and would require highly persuasive evidentiary support, which is wholly absent in this case.”). At this stage, we interpret the scope of the “location access rights of said device from said first wireless device” to encompass at least the disclosed embodiment of assigning access rights to a group. Ex. 1001, 13:9– 12.” slip op. at 14

      “Petitioner argues that a person of ordinary skill in the art would have made Petitioner’s proposed combination of “Degnbol’s disclosure of both selection of location-based events and manual entry using the handset of the phone with Sheha, to improve user ease, given that such techniques were well-known and conventional to POSAs at the time of alleged invention.” Pet. 18 (citing Ex. 1003 ¶ 132). Degnbol describes that “[i]t is an advantage of the present invention that user ‘A’ can be alerted when user ‘B’ arrives or leaves the defined location(s) or area(s)” so as “to enable user ‘A’ to know in advance the proximity or approximate whereabouts of user ‘B’ before possibly acting upon this information by contacting user ‘B’ — or allowing ‘B’ to contact ‘A.’” Ex. 1035, 3:23–27. At this preliminary stage, we find that Petitioner provides sufficient rationale to combine the teachings of Sheha, Degnbol, and McNulty for purposes of institution. Based on the evidence and arguments currently of record, we find that Petitioner demonstrates sufficiently for purposes of institution that the Sheha, Degnbol, and McNulty combination teaches the features recited in claim elements [1D] through [1F] and Petitioner provides sufficient rationale to make its proposed combination. We find that Patent Owner’s arguments do not undermine Petitioner’s showing. c) Conclusion—Claim 1 After consideration of the arguments and the evidence of record at this early stage, we determine that Petitioner has shown sufficiently, for purposes of institution, that the combination of Sheha, Degnbol, and McNulty teaches or suggests all recitations in claim 1. Also, we find that Petitioner provides sufficient rationale to combine the teachings of Sheha, Degnbol, and McNulty for purposes of institution. We find that Patent Owner’s arguments do not undermine Petitioner’s showing. Based on the record at this preliminary stage, we conclude that Petitioner has demonstrated a reasonable likelihood that it would prevail in showing that claim 1 is unpatentable under 35 U.S.C. § 103 as obvious over the combination of Sheha, Degnbol, and McNulty.” slip op. at 28

      “On this record, in considering the background knowledge as well as the inferences that an ordinarily skilled artisan would draw from Sheha’s disclosure, we are sufficiently persuaded that a person of ordinary skill in the art would have caused the mobile telephone to display the map of Figure 5. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 418 (2007) (In an obviousness analysis, a court will “look to . . . the background knowledge possessed by a person having ordinary skill in the art” and “can take account of the inferences and creative steps that a person of ordinary skill in the art would employ.”). The references cited by Mr. Williams explicitly show what is already implicitly taught by Sheha, namely, that displaying the map of Figure 5 on a mobile telephone was within the background knowledge of a person of ordinary skill. Ex. 1003 ¶¶ 138–144; Ex. 1007 ¶¶ 2, 21, p. 85; Ex. 1016 ¶ 27; Ex. 1014, 3:28–31, 4:43–58; Fig. 4B; Ex. 1017, 4:38–57, 5:13–17, 6:14–27, 6:59–7:6, Fig. 2; Ex. 1018, 2:2–7, 3:59–67, 5:48–57, Fig. 4B. We agree with Mr. Williams, that a person of ordinary skill in the art, in light of the teachings of Sheha and his or her background knowledge, would have caused a mobile telephone to receive location information without initiating a telephone call and would have used the location information to display a map on the mobile telephone in a form similar to that shown in Figure 5 as taught by Sheha and as was well known in the art.

      “We disagree with Patent Owner on this record. The language of claim 1, quoted above, recites “changing, at the direction of said first wireless telephone, a list of users on said remote server for a profile associated with said first wireless telephone that are allowed to access said location, wherein each user of said list of users is representative of one of a plurality of wireless telephones.” Ex. 1001, 12:65–13:3. The recitation of “said location” derives antecedent basis from element [1A], which recites “obtaining a location of a first wireless telephone,” thus “said location” in element [1C] is the location of the first wireless telephone. Id. at 12:62.7 The claim language does not limit access to the location of the first telephone to one other device, at the exclusion of other devices. Indeed, the claim language specifically recites that “a list of users” are changed “for a profile associated with said first wireless telephone” and that “each user of said list of users is representative of one of a plurality of wireless telephones.” Ex. 1001, 12:65– 13:3 (emphases added).
